If you break apart an 8GB file with Xenon, do you run into issues playing back files larger than 2GB? I've always noticed whether it's a divx file or mkv file, anything larger than 2GB won't let you seek properly and the video tends to slow down and doesn't stay in sync with the audio.
[Xoom General] alias_neo:
Fantastic, I'll try it out on my mkv collection tonight when I get home, does it support batch processing?
[Xoom General] keitht:
There is an option to convert a single file or entire folder. Haven't tried the entire folder yet.
[Xoom General] Digital Man:
Very little change in file size - remember this app is not re-encoding the video, so there isn't any change in terms of bit rate or compression - whatever video you started with is what you get in the output. The only thing that is changing is the audio track and the container. It's just dis-assembling the video and audio. Then it re-encodes only the audio to a XOOM-compatible format ie AAC (thats where the change in file size occurs) and then it puts the whole thing back together in a container that the XOOM can play.

As for 1080p I don't see why it wouldn't convert a 1080p video - will try it out soon and see. But whether the XOOM will play it will depend on the profile of the video ie whether the XOOM can natively play the 1080p video file itself - and the XOOM is not as good at high profile 1080p as it now is at 720p. Again this program isn't converting video - its only taking advantage of the fact that HC 3.1 now seems able to handle most 720p h264 video files without conversion.

Yes it does support batch processing. Sometimes though, you may want to set the options to pause at the start of each file to manually select options like aspect ratio or audio track. I found that in one case, left on the automatic mode, it got the aspect ratio of my videos wrong, and setting it manually for each file corrected the problem. What the program does is it just pops up a prompt on the screen at the start of each file and asks you what aspect ratio or audio track you would like for each file - again this is optional. You can also have it automatically select language-tracks and aspect ratio if you want.

Thanks for the tip. I've been thinking of trying out and listing some of the alternatives, in case anyone has trouble installing or using XenonMKV. Might be something even better out there. Though XenonMKV does seem to do the job pretty well.
[Xoom General] keitht:
Digital Man: Really appreciate your efforts on this and sharing your experience. I think it would be a good idea to consolidate what has been learned into one post (OP) for a sticky here, basically a dummies guide. This issue with video conversions has been a sour spot for me from day one. Thanks again!

Took a little over a minute to convert on my desktop.
[Xoom General] Lakota:
Cracking bit of programming

What a fab bit of software.

I've just converted the Smallville series finale from MKV to mp4 using this program on my laptop. Took just over 12 minutes to complete the 2.3Gb file. It converted to 2.16Gb and plays just great on my Xoom using either the built in Videoplayer or RockPlayer.

This is a much needed bit of software. Thanks.
[Xoom General] e.mote:
@alias_neo

If you would, please cut a clip from the original movie (not the output) and post it. Make the clip long enough so that the problem still exists when converting.

Since the orig clip already has AAC audio, it should be a simple remux with no audio processing.
[Xoom General] Digital Man:
alias_neo Try setting the fps/frame-rate manually if AV is out of sync, don't trust the default setting. (Edit - sorry alias_neo disregard this - forgot you don't have access to the fps settings in Xenon - only in the manual tools) I've gotten a few videos that didn't convert as well. But not many. I noticed that the original appeared to have AAC audio and was relatively low res. I kind of think that video should have played even as an MKV without converting maybe even in Rockplayer or Mobo in software mode. The only thing that Xenon would have done is change the container.

Yes I've been using it for lots of downloaded TV show MKV's as well. Has worked for all of them. Its been a little more hit and miss with movies. A couple have failed in Xenon, but then have worked when I used the separte tools and manually converted.

Oh - and on the Smallville series finale - Plot was kind of choppy and rushed but there sure was a lot of setup at the end - wonder if there is a movie in the works - and not a single closeup of Clark in his Superman getup! - guess they figured imagination is more powerful.
[Xoom General] thor17:
I got similiar results with gotsent, but I like the GUI of XenonMKV better - it's easier to tell the current progress (gotsent opens and closes a bunch of cmd windows).

If your sourcefile is 1080p main or high profile, then you will have similar results as e.mote's other thread. Your xoom will say that the file is not playable.
[Xoom General] thor17:
after you unzip the file, click on xenonMKV.exe
[Xoom General] Digital Man:
Yes, I kind of figured that. This solution is only useful for 720p MKV. Still going to need DVDcat or Handbrake when dealing with most 1080p files.
[Xoom General] DroidHam:
Isn't it just better to use a 720p source than use a 1080p in DVDCat? Isnt a virgin 720p image better than a re-encoded 1080p, plus all the time saved?
[Xoom General] Digital Man:
For me it would be preferable to use the original 720p source hands down. That's why I like this software so much. People say "why not just use DVDcat or handbrake rather than this?" But this lets you watch the original video and the quality is usuall really good on the XOOM - a lot better than a fast re-encoded video full of aberrations.

But there are cases where you might not have a 720p source, like a downloaded video in 1080p high profile. And there are some 720p videos that just won't convert with this method for whatever reason. In these situations your only option is to re-encode the video in something like DVDcat or handbrake.

Edit: Just re-read your original question. I think what you were asking was why was I suggesting to re-encode from 1080p and was I implying that this might be better? That wasn't the reason for re-encoding from 1080p. Its because the XOOM simply can't play most of these even after converting audio and container in Xenon, and so you are forced to convert. But if you have an alternate 720p version of your video, watching the original, without re-encoding would certainly be my preference.
[Xoom General] wite:
I have tried to convert several mkv files now and they all end up unplayable on my xoom, when I checked the details on my converted files in windows it says frame rate 23980 frames/second and I´m guessing this is why the files wont play. Can I specify the framerate in xenonmkv somewhere? Or how can I fix this?
[Xoom General] cantellay:
Works good Thanks

Thanks for the application, I am know watching Game of Thrones on the Xoom :)

Sean
[Xoom General] Digital Man:
Unfortunately no. That's why I left the manual tools at the bottom of the original post. Mp4BoxGUI when used separately does allow you to set framerate and in a few cases I had to do it manually because the automatic setting wasn't correct. But when the muxing tool was included in XenonMKV, it lost that option and you are apparently stuck with the automatic setting.

I might point out that the wrong framerate should not make it unplayable, would more likely just put the audio out of sync. If it is truly unplayable, there is likely something else going on.
[Xoom General] tsunami1609:
Problem

I've tried this as well as m4v files, and while the stock video player supports both, my Xoom seems to have issues playing them, particularly in scene's with large content (fast paced action scenes or even slow ones with a lot of detail). I've tried Inception (the easiest to notice problems with), Scott Pilgrim vs the World, and Iron Man 2 and each of them brings up these issues. They're all 720p, so I don't know what the problem is. I have a Xoom non-rooted running 3.1

Can someone else try any of these movies and tell me if they're having the same problem? In Inception, the first 30 seconds are easily noticeable (just play it on your xoom side by side with your computer). I just want to know if it's a common issue, or my particular xoom, in which case FML. Thanks
[Xoom General] yao847zi:
That's really great information. No conversion, a great idea:D
[Xoom General] DroidHam:
I just converted a 720p rip of Kill The Irishman...

it converted it into 2 files, the 1st smaller than the 2nd.

it skipped/froze on my Xoom 2 minutes in.

put it on a external HD and played on my bluray player, it ran but skipped alot too. Any ideas?
[Xoom General] Epedemic:
Im having strange issues with xenon.... on my work pc with xp it works fine... but on both my home pcs with win7x64 the same videos just turn into a very narrow horizontal bar in the center of the screen when played on my xoom
[Xoom General] tsunami1609:
Better Playback

I have a non-rooted Xoom and the playback on some of these videos is sub-par. If I overclocked it, would there be an increase in video playback performance?
[Xoom General] Epedemic:
Tried with win7 32 bit... same result... strage...
[Xoom General] Digital Man:
Try this: Under options/tracks select: Prompt me to provide a cusotom display aspect ratio DAR for each file

When you convert your video and the prompt comes up select: 16x10 if that doesn't work try 16x9
[Xoom General] Epedemic:
Now i tried that, and that fixes the aspect... (stupid me...) But now i have a problem that it just plays the first ½ second, and then just the audio... Frustrating...
[Xoom General] mug2k:
Is there any way to keep 5.1 audio track when converting with Xenonmkv ?. The reason I ask is because I want to convert my current library but still have the 5.1 to use when watching movies via my HTPC.
[Xoom General] e.mote:
Per Xenon's homepage, no.

http://xenonmkv.ev98.net/

The purpose of remuxing to MP4 is to avoid software decoding. 5.1 AAC (or anything) in MP4 container isn't natively supported by HC 3.x, and would incur SW decode. If you want 5.1 audio, just keep the MKV and run it in software mode.
[Xoom General] mug2k:
It won't play like that because its high profile. So it seems like I'll have to have a separate library for the tablet :(
[Xoom General] e.mote:
See if the clip below plays smoothly on your Xoom:

http://mediafire.com/?909217fe7z4272p Avatar clip 720p HP w/ 2.0 AAC, 5.1 AAC

It has two audio tracks, first is 2.0 AAC, second is 5.1 AAC. If the Xoom can handle dual-audio MP4, then it should correctly play the first track. For your HTPC, select the 2nd track for surround.
[Xoom General] mug2k:
Worked fine on my Asus Tranformer, just slowed down a tad when the beast was shot in the eye and I was able to watch it fine with both audio tracks on my HTPC. How hard is it to reencode the files to have 2 audio tracks ?, does it add much time to the conversion process ?.

I converted Battle: Los Angeles earlier in Xenonmkv and it took around 19 minutes but unfortunately I lost the 5.1 track. Do these converted clips definitely not work when only a 5.1 track is present ?.
[Xoom General] e.mote:
I had a test MP4 (same clip) w/ 5.1 AAC track in the video survey thread, and those who've tried it said 5.1 can't play correctly in native model.

I can't speak for XenonMKV, but it basically doubles the audio processing time, since it has to be encoded twice. Audio processing is 10X speed, so instead of 9min for a 90min video, it'd take 18min. I may add this as an option to my script.
[Xoom General] mug2k:
Is the audio processing time fixed at 10x ?. How long is the average film conversion using your scripts ?.
[Xoom General] e.mote:
It depends. Youtube FLVs and most Apple videos convert in seconds since nothing is converted, just a remux. If audio is converted, then typically 10X. If audio & video, then 1-5X, depending on host PC and resolution selected.
[Xoom General] e.mote:
BTW, an alternative is to use Handbrake. It allows for multiple audio tracks in MP4. Its drawback is that it always recode both audio & video, and will take substantially longer than a remuxer.

If you're going to use HB, no need to look for "special" Xoom presets. Use the AppleTV2 preset, and change the audio setting to suit your needs.
[Xoom General] mug2k:
Rather convert my whole library I'm just gonna bulk convert as and when I need to such as taking some films with me when going on holiday etc for now I'll just use plex whilst at home.

Is Xenonmkv the fastest option if I'm just looking for simple conversions ?.
[Xoom General] e.mote:
I've no experience with other "remuxing" or converting solutions, as I cobble my own solutions via scripts, a couple of which were posted on this forum. There are others mentioned in this thread. GotSent, Videora Xbox Converter, etc. You can try them and see.

I think your solution is best, to convert as needed, and keep separate copies for the interim. A better media player with native support for MKV will come along, as will a better SoC that can handle a fuller range of content.
[Xoom General] sierra77:
Hello All,

I could use some help with this...First of all i'm not using a xoom but a transformer. The problems already start whem playing back converted files on my win7 x64.

When a file was converted I tried it with;

1: VLC--> Garbled / Scrambled frozen picture with good sound

2: Quicktime: 1 second picture then all white with good sound

3: Win Media player: good sound, good picture but framerate is waaay too high, so its like looking at fast forward with normal rate sound

When I send the file to my transformer it shows one frozen frame which does not appear to be the first frame of the file, the soundd continues to plays well from the beginning.

The above happens when I convert to 16:10 as well as 16:9

Thanks :) I'd love this to work...

PS I tried the Avatar clip posted e.mote and it worked fine on the transformer..
[Xoom General] stefan.li:
I can't get this to work the output files wont even play on my PC. I don't get promted to set aspect ratio or nothing. Tries different mkv files.
[Xoom General] evernn:
all i did was

1. select the presets to normal or custom made one for my ps vita

video tab

2. change the video codex to H.264(x264)

3. frame rate to same as source

4. Quality to RF 20(Those two option determine your video quality 0 means lossless and meaning a bigger file size the the original unless the original is lossless already)

and advance is default and video filter tab off everything eles should be default

For our freedom...

- replace the bootloader itself with an unlocked version suitable for milestone (no one knows if this piece of code even exists)

- the private key for signing custom images which would allow to work in harmony with existing bootcode (this key for sure exists)

Perhaps you might join an internship at motorola :D

Good luck!!!

[Motorola Droid and Milestone General] HinotoriBR:
Usually, decent companies have the keys stored in a safe place and those can't be accessed by employees, they only have means to access it remotely to request something to be signed by that key. In that safe place, that could either be owned by the owner of the key or leased in some specific digital security company (like Verisign), security measures are taken that only few people have access and those are properly identified, so, any leak would be easily spotted and that person would be charged.

But, is Motorola a decent company? :p There is always some hope that they have the signing application lying around in a network share that is not logged, but, I would imagine if that was true, that piece of software/keys would already be released by someone.

Ok so in my room I have one of the older Hitachi plasma tv's that was made before they started putting HDMI in as standard. Still in great working condition so I really see no need to upgrade it for now. Now my question is.. it does have these OTHER ports that look kinda like HDMI ports but I know they arent. Anyone know of like some sort of special cable or adapter I could use to go HDMI direct from the phone to the tv?
[EVO 4G Q&A, Help & Troubleshooting] Cares:
You can get something like this:

http://www.amazon.com/GefenTV-HDMI-to-Composite-Scaler/dp/B0013LTNF8

Obviously this is a pretty expensive option. I did a 10 second Google search and found this. I'm sure there are cheaper methods.
[EVO 4G Q&A, Help & Troubleshooting] rugedraw:
If it's an HDTV, then it either has a DVI input or component inputs. If your TV had DVI, you can use something like this with the regular EVO HDMI cable:

http://cgi.ebay.com/DVI-D-HDMI-Adap...836?pt=LH_DefaultDomain_0&hash=item20b96e20fc

If your TV only has component inputs, then you need an actual converter box like this:

http://cgi.ebay.com/HDMI-5-RCA-Comp...024?pt=LH_DefaultDomain_0&hash=item2a0d942cc0

What Cares posted is a scaler that actually converts an analog signal into digital. You already have a digital signal being sent from your phone via HDMI to a digital TV, so all you need is a converter/adapter.....you don't need upscaling.

Hope that helps..........
