[Galaxy Note 10.1 General] D4747:
What are the settings I can use so the writing is as smooth as say sketchbook pro for tablet or Snotes? If i enable the 'discared coordinates between android events' filter, the jittery goes away at the end of strokes, but loops and curvers are less smooth. I have the pressure setting at 5%, enforce lifting disabled (duno wat that does), and ramer-douglas filter off at the current time. I also find the lag between writing and seeing the ink on screen is least with Snote, more with sketchbook, and most with Lecture notes.

The one feature i just need is a large canvas I can scroll, S notes doesnt seem to allow that. Lecture notes is the only hope, plus it has the feature to remove the action bar and system bar so it is nicer. Issue with system bar is that on return, the background is gone until i restart my system.

Dev, can you tell me how to replicate the thinnest pen in Snote? With thickness, smoothness, and other settings? Try drawing circles and loops in Snote, very fast and smooth. Would be nice if that can be replicated.
[Galaxy Note 10.1 General] acadoid:
[MENTION=4489422]D4747[/MENTION]: I recommend to disable all filters but the pressure one and adjust the threshold to 5%. The option `enforce lifting the stylus´ requires you to lift the stylus between two strokes, increasing the pressure above threshold will not be sufficient with the option enabled.

Please double-check that you have not enabled `enforce GPU/hardware rendering´ in the device's developers settings, this slows down LectureNotes a lot.

That a static wallpaper is reset is a known issue in hiding the system bar on newer Android versions, to my knowledge there is no fix for that.

In case you need thinner pencils, use one of the custom pencils.

LectureNotes uses a running cubic interpolation, so that curves are smooth up to second derivative. It does, however, not replace your drawings with geometric shapes (for instance something that is close to a circle by a perfect circle).
[Galaxy Note 10.1 General] D4747:
Thanks for response. The second filter, disable between android events, is the only way I can get rid of squiggly trails at the end of letters. Without it, the bottom tip of say an 'e' is more 'zig zag'. I will try disabling the hardware acceleration thing and report back over the weekend.
[Galaxy Note 10.1 General] acadoid:
[MENTION=4489422]D4747[/MENTION]: So far, all users have reported that the pressure filter with a threshold 5% to 10% does best in removing the strange tails.
[Galaxy Note 10.1 General] D4747:
Attaching screens to show difference in smoothness on my device. Brown background is S note. White is lectures notes. Hardware accelerated GPU was already off. threshold set at 7% in these screen. With pressure (only used in the screen saying pressure), the squiggles are even more pronounced. Other screens use no pressure sensitive pens. Notice the strokes for t's, e's, and even straight lines in lecture notes aren't smooth compared to S note. End strokes for e's are especially unpleasant while writing.

Edit: it seems more minor looking at screenshots on the desktop, but while writing on the tablet, the inaccuracies are more bothersome than it might appear in screens. the writing is bigger on the tablet, jitterness more pronounced.
[Galaxy Note 10.1 General] acadoid:
[MENTION=4489422]D4747[/MENTION]: How does the result change if you increase pressure threshold to 10%?
[Galaxy Note 10.1 General] D4747:
Not any better. The only way I can get rid of those dips on the end strokes is by applying the 'discard between events' filter.

I think in Snote, it gets the input that produces those dips too, but it corrects for them. For instance, if I try to write as soon as I click edit in Snote to edit the current page, the dip will appear there too, as if it is not done yet switching completely to editing mode. But after it is ready, a second after clicking edit, the dips no longer occur.
[Galaxy Note 10.1 General] D4747:
Attached writing letters. 10% pressure filter. White bg is lecture notes. Notice the c, e, g, j, r, t, z all have problems compared to Snotes version.
[Galaxy Note 10.1 General] acadoid:
[MENTION=4489422]D4747[/MENTION]: Hmm, rather strange. It is difficult to see how the option `discard coordinates between Android events´ affects the tail of the line, as this option makes LectureNotes discards intermediate coordinates, not the last coordinate causing the tail, which comes from an actual Android event.

At the moment, LectureNotes applies a cubic interpolation between coordinates, so that the drawn line definitely goes through the coordinates. One user suggested in a different context to apply instead a fitting procedure such as the Savitzky–Golay filter, then the drawn line would not necessarily go through the coordinates anymore, but could be better smoothed. As adding such fit/filter affects the very core of LectureNotes, it needs quite a bit of thinking, so that I have to ask you for some patience.
[Galaxy Note 10.1 General] D4747:
Since it is Samsung's device and a critical feature for them, is it possible Samsung is willing to tell a developer like yourself how to get the writing as smooth as they did? It seems beneficial to them to just give the exact code they used for writing in Snote... Maybe it is in the SPen SDK but I assume you've already looked into that. Maybe you can ask them?
[Galaxy Note 10.1 General] acadoid:
[MENTION=4489422]D4747[/MENTION]: Samsung's SDKs are binary only, and I doubt whether they will share such information with me.

The problem is that unfortunately (or, luckily, depending on your point of view), I do not see these tails on my testing device (they occur only on some devices), this makes it hard to fix it.
[Galaxy Note 10.1 General] Canguy247:
Any way LectureNotes can do this automatically? (like once a day at night)
[Galaxy Note 10.1 General] acadoid:
[MENTION=4489422]D4747[/MENTION]: I added an adjustable Savitzky–Golay filter to LectureNotes, but for me it is a bit difficult to judge whether or not it will solve the problem that you reported. Would you be willing to test it on your device? If you contacted me by email, I could provide you with the APK of the trial version (to avoid interference with your full version) by email.

[MENTION=5144453]Canguy247[/MENTION]: In principle, this could be done, but such automatism comes with a couple of disadvantages, for instance it can easily drain your device battery.

I was thinking it would be awesome to run it nightly when charging...
[Galaxy Note 10.1 General] acadoid:
[MENTION=5144453]Canguy247[/MENTION]: OK, I put that on my to-do list.
[Galaxy Note 10.1 General] kminatta:
i am also getting the little squigglies at the end of my letters on a Note 10.1. i'm using the free version for now.
[Galaxy Note 10.1 General] acadoid:
[MENTION=957365]kminatta[/MENTION]: Have you tried to enable the pressure filter with a 5% to 10% threshold in the filter setup in the app's input settings? In the vast majority of cases, this removes the strange tails.

The Savitzky–Golay filter I mentioned is not yet part of the version in the app stores.
[Galaxy Note 10.1 General] acadoid:
[MENTION=4489422]D4747[/MENTION] & kminatta: I just uploaded v2.3.11 into the app stores in which there is a fourth filter, a Savitzky-Golay-filter of adjustable order (larger order means more smoothing).

Hi,

I have just got lecture notes but I'm not sure on how to go about certain functions.

1) Can I mass import pdf into the app?

2) Auto save as pdf file(additional separate file as the default format is ok) so that my dropsync can sync it with my Dropbox?

3) Any possible way of adding words, ppt etc too?

Thanks
[Galaxy Note 10.1 General] acadoid:
[MENTION=4644157]davidlondono[/MENTION]: That is still on my to-do-list. LectureNotes' user are quite creative as far as suggestions are concerned (my to-do-list contains presently more than 200 lines) so that it can take a moment until a specific suggestion gets added.

[MENTION=4463015]earthtk[/MENTION]: 1. No, not yet.

2. No, but I am considering automatic PDF export of modified notebooks.

3. No, you need to convert these files to PDF first.
[Galaxy Note 10.1 General] earthtk:
Hope you might consider the 1. and implement 2. too! Cause I'm new to this program and I have tons of notes to import. :D

I came from notability (ipad), was quite a powerful tool with simple UI. I know android has their own complexity and yours is the best so far.

Some UI improvement that I could suggest is to have, a "list" mode to view notes and a randomiser of colour/design of the notebook covers

Anyway I'm wondering is it normal for imports of 100 pages pdf to take about 10 minutes? I'm using 400 DPI as anything lower makes my notes look jittery. What would be the best resolution and dimension for a land scape A4 size?
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: I am not entirely sure what you refer to as `list mode´, but LectureNotes has an ultracompact variant of the notebooks board (notebooks board setup in the app's display settings), including a tree-like arrangement.

Cover color randomizer is an interesting idea; one way to randomize the color is to randomly rotate the color wheel. Note that a click on the cover cycles through a couple of standard colors.

Which resolution is best for PDF import depends on paper size.

Let's say you have a notebook of 1280 times 1811 (which is an A4 portrait aspect ratio) and you import A4 portrait PDF. The width of A4 portrait is 21cm, which is 8.26772inch, and 1280dots divided by 8.26772inch yields 155dpi, so that the optimal resolution would be 155dpi.

Let's say you have a notebook of 1280 times 904 (which is an A4 landscape aspect ratio) and you import A4 landscape PDF. The width of A4 landscape is 29.7cm, which is 11.6929inch, and 1280dots divided by 11.6929inch yields 110dpi, so that the optimal resolution would be 110dpi.

If you have set margings, the optimal resolution changes accordingly.
[Galaxy Note 10.1 General] earthtk:
Alright thanks! Saw the list view. I'm not sure if it is because of my screen that causes the the lower quality as I'm using a note 10.1 2014.
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: On the Nexus 10 or the 2014 edition of the Galaxy Note 10.1, you should use notebooks of higher resolution. Click on the `?’ aside `paper size’, then LectureNotes gives recommendations based on the device orientation. For instance, 2560 times 1008 is recommended as A4 landcape on a device in landscape orientation, so that the optimal resolution is then 220dpi.
[Galaxy Note 10.1 General] earthtk:
Alright thanks! I found out that my imported pdf is around 9mb but exported about 50mb sized pdf. Is there any way to reduce the size without compromising the quality?
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: When you import a PDF file, it is converted to LectureNotes' own format; exporting the notebook in PDF can yield a smaller or a larger file size, dependent on content. One way to reduce the file size of PDF files exported from LectureNotes is to export in grayscale (I added such option in v2.3.11), this will reduce file size to about 1/3 (which would yield approx. 17MB in your case).
[Galaxy Note 10.1 General] earthtk:
Aright. thanks for your help.

Android takes quite long to process a PDF file.. I realize that on s note too.. I could import and export any PDF file in seconds on my ipad with no quality loss and similar size. Kinda regretting buying a note 10.1 :(. Anyway I will just make the best of it.

EDIT: I had some problems with lecturenotes with an error that pops up saying Lecture notes has stopped when I tried exporting notes into PDF. Any solutions?
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: Sorry to hear that. In case it occurs again, please click on the `report’ button, this will place a report in my developer console at Google Play/Amazon which will allow me to localize the problem.
[Galaxy Note 10.1 General] earthtk:
I have reported it. Thanks
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: Did you download LectureNotes from Google Play or from Amazon (and correspondingly upload the report to Google Play or Amazon)? I do not see any report, neither in the Google Play nor in the Amazon developer console.
[Galaxy Note 10.1 General] earthtk:
I have sent the report again. See if you can receive it. Its from google play.
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: Quite strange, still no report in my Google Play developer console. Reports usually show up within 10 minutes or so. Did you have internet connection when you clicked on `report´?

Do you know how to read the logs of your device?
[Galaxy Note 10.1 General] earthtk:
Yup mine is LTE so definitely I had Internet access when I hit the report button. Should we do pm instead? Im not sure how to check the log but you can tell me the directory
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: Quite weird, there is still no report in my developer console at Google Play.

The easiest way to read the logs is to connect the device to a `normal´ computer via USB and to use tools such as logcat.

I think that the Google Play app stores the report on the SD card inside a folder called `bugreports´ or similar. Could you please check whether there is such folder on your device and what is inside?
[Galaxy Note 10.1 General] earthtk:
Hmm nope. Mine is not rooted so probably I can't see that folder. I have reported again see if you can receive it
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: Very weird, I have not received any of your three reports.

The directory `bugreports´ should be in the root of the SD card; when you start a file manager app, they usually display the content of the root of the SD card, so that you should directly see it. No root permission required to read these files, you should be able to open them in a normal text editor app. These files might be pretty long, maybe better not to post them here, instead send them to my by email.
[Galaxy Note 10.1 General] earthtk:
There is no such folder =(... Anyway this problem happens when I try exporting files more than 100 pages.
[Galaxy Note 10.1 General] acadoid:
[MENTION=4463015]earthtk[/MENTION]: Hmm, maybe the non-existance of this directory indicates that no bug report is actually sent.

This message is for the developer of Lecturenotes.

This is a fantastic product and I'm really enjoying it with the Recordings and Videos addon but I'm having some issue with the video sharing.

When I share a video via email the only thing that plays is the audio, I don't see the video portion. If I try to share via YouTube, the YouTube upload screen appears but then shuts down before I can even set the title.

What am I doing wrong?

I have a Samsung Galaxy Note 8.0

thank you!

[MENTION=5517601]aaronjw76[/MENTION]: LectureVideos entirely relies on the Android MediaCodec and does neither contain any codecs nor any other encoding, decoding, multiplexing, or demultiplexing code (mainly to avoid legal problems). The Android MediaCodec APIs of Android 4.1 and 4.2 do not provide a multiplexer to create a container format such as MP4, AVI, or MKV. Therefore, LectureVideos produces two files per session, an H264 file containing the encoded video signal and a 3GP container file containing the encoded audio signal.

On devices running Android 4.1 and 4.2, you need an external tool such as FFmpeg to multiplex the video and audio signals into a container file. Lets say you have video1.h264 (the video stream) and video1.3gp (the audio stream), you can produce an MP4 file using the command

ffmpeg -r 12 -i video1.h264 -i video1.3gp -b 1.5M video1.mp4

where `-r 12´ states the frame rate (12 frames per second) and `-b 1.5M´ sets the output bit rate to 1.5Mbits per second. The resulting MP4 container file video1.mp4 can be viewed with all video viewers and uploaded to YouTube and other video platforms. There are graphical user interfaces available for essentially all OS, so that you do not need to worry about command line options.

There are FFmpeg ports for Android available in Google Play, but I would rather recommend to perform the multiplexing on a `normal´ computer.

There are alternatives to ffmpeg such as mkvmerge (which produces an MKV container file), one LectureNotes user published a short video on that, http://www.youtube.com/watch?v=kTTc-2EtPAw.

On devices running Android 4.3, you can still use an external tool to multiplex the video and audio signals into a container format (which can be advisable if you have specific optimization needs, for instance for streaming); furthermore, you can share the video as an MP4 container file in LectureNotes, and LectureVideos uses the Android MediaCodec API to multiplex the video and audio signals into the MP4 container format prior to sharing.
[Galaxy Note 10.1 General] aaronjw76:
Thanks acad for your reply! Seems like an annoyingly cumbersome process for now that I'm wondering why you'd provide the sharing option in the first place. Either way, great software.

I do a lot of teaching vids for kids I tutor (University level mathematics) and having a direct share option would be amazing. Alas I guess I'll need to wait for android 4.3 to be available!

One further question... is it possible to have a page scroll instead of having to add new pages? If I'm doing a video and I use the whole page it would be great to just scroll indefinitely If I didn't want to move to a new page. Any options for that?

Thanks!
[Galaxy Note 10.1 General] acadoid:
[MENTION=5517601]aaronjw76[/MENTION]: As you might know, video production is a legal minefield with a patent lawyer under every stone...

Multiplexing a video and an audio stream into an MP4 container is less complicated than it might sound. As I wrote, there are FFmpeg ports for Android, so that you can do that on your Android device.

LectureNotes uses notebook pages of fixed size. You could add a number of pages before starting the video (there is a `Append multiple pages´ item in the `hand´ menu), there is not too much difference then due to the continuous page view.
[Galaxy Note 10.1 General] aaronjw76:
Thanks for the explanation. I can't wait for 4.3 to be released because it would make video distribution a whole lot easier. I am knew to the Android world and only just bought this Note 8.0 a few weeks ago for the native writing recognition so an all in one ability for distribution using lecturenotes would be amazing :)

Another question since you post on the forums here... If I have a PDF with multiple pages like say 18, how do I import all ALL the pages? Right now it seems as though I can only import one instead of a whole document.

thanks very much :)
[Galaxy Note 10.1 General] acadoid:
[MENTION=5517601]aaronjw76[/MENTION]: To import multiple pages of a PDF file at once, open your notebook in notebook overview (either directly from the notebooks board by a long-click and selecting `Notebook overview´ in the popup, or by opening the notebook normally and selecting `Notebook overview´ in the main menu) and select `Import PDF file as new pages´ in the main menu. To create a new notebook based on a PDF file, select `Import PDF as new notebook´ in the notebooks board main menu. An alternative is to open (or to share) the PDF file and select LectureNotes in the list of viewer (or receiver) apps, then LectureNotes will ask you how you wish to import the PDF file. The resolution, margins, and alignment can be be adjusted in the app's import settings.
[Galaxy Note 10.1 General] D4747:
Sorry. I gave up on the app. Thanks for trying to help. The speed and smoothness in writing just doesn't come close enough to S note. Every other feature is better, but the writing is too bothersome for me. This is also considering the new filter you added. Even if you got smoothness to be the same as S note, if the lag in writing is still there compared to S note, i'll have to go with s note as I write fast and lag gets in the way.

Margins and Text Boxes

2 questions ...

1) How to set margins for keyboard text? They seem to be flush to the right and left and I cannot find the settings.

2) After creating and entering text into a text box, how do ylu go back and edit the box? I cannot long click nor select it after I have moved on to other stuff and come back.

Thanks!

ALG
[Galaxy Note 10.1 General] acadoid:
[MENTION=5425241]ALGshekou[/MENTION]: 1. The margins can be adjusted in the text layer setup in the app's handling settings; note that any change applies to all notebooks.

2. LectureNotes is bitmap-based, not object- or vector-based. Both approaches come with pros and cons. One con of a bitmap-based approach is that LectureNotes does not keep track of text boxes as objects, so that the text cannot be altered (besides erasing and redoing, of course).
[Galaxy Note 10.1 General] ALGshekou:
** Thanks! **

I found the margin settings. Much appreciated.

I understand the text box cannot be moved or edited. Not a problem ... I can adjust for this.

And a HUGE thanks for the quick reply!

FYI ... this is a great app ... makes my tablet SO much better!

Great point ... that makes it easy to adjust the page after writing ... makes the layer options more important as well ... especially with backgrounds ...

More questions ....

I want to export the LectureNotes notebook to Evernote.

It is quite easy with the "export to evernote" command.

The png image shows up nicely.

Any text in the notebook gets added as a .txt file.

Is there a way for this text to get added as text in the Evernote note?

FYI ... S-Notes can export via "text" to Evernote, this adds the text into the body of the Evernote note, then as a separate operation I can export the image (jpg) and attach it to the note. Very cumbersome but the text feature is nice.

ALG
[Galaxy Note 10.1 General] acadoid:
[MENTION=5425241]ALGshekou[/MENTION]: One can create a PNG of the text layer prior to export; interesting idea, I noted it down.

Note that LectureNotes can merge layers prior to export (if you disable `individual layers´ in the Evernote export settings) and that this merging includes the text layer.
[Galaxy Note 10.1 General] acadoid:
[MENTION=5425241]ALGshekou[/MENTION]: I just uploaded v2.3.15 into the app stores in which LectureNotes creates `evernoteX_text.png´ containing the text layer upon export to Evernote (and if you have enabled `individual layers´ in the setup, otherwise the text layer gets merged with the other layers as before).
[Galaxy Note 10.1 General] ALGshekou:
Great! Sometimes it's good to get the text as separate pngs.

One other thing .... text also arrives in Evernote as a .txt file attached to the note. Is it possible to have the text also inserted into the note? As if you had typed it in? So it would be edit-able when the note was opened?

What I will do with the current method is export to Evernote. Then open each attached .txt file, copy the text and insert it into the note. If the text was inserted during the export, I would not need to do this step.

ALG
