content: I just wasted a whole day of research and shooting video for my new Wayback Wednesday segment to find (once again) that my Canon HF G10 camera failed to record the video like it said it was doing by flashing the little red record icons.To say I'm angry is an understatement, and no the files are not recoverable, I've tried 3 different programs.Some of you may know this has happened before.I will not let this camera destroy my sanity again. I want a new camera.Suggestions please on a high end video camera to replace the Canon HF G10.But PLEASE do not mention a DSLR, they don't do the job properly for my purpose and I don't want one.

Or try fixing it with a big hammer?Quote from: pickle9000 on July 23, 2014, 07:21:21 amTypically you would want as flat image as possible to have more to work with in post? But Dave doesn't do any color correction/grading or fancy stuff...Quote from: EEVblog on July 23, 2014, 07:13:38 amnot much choice there.Canon XA25, same sensor, same lens thread, but same batteries will not work. Yes it has long 20x zoom, which might not be needed, but other things are also upgraded.more professional camera, maybe more durable and reliable?From what I've understood the camera has been used really hard and one SD card slot is already dead and now it has developed this issue of not recording. Using pro-sumer camera for so long, something has to give eventually. I think the important bit is that your camera is already partly faulty, yet you choose to use it and hope it functions correctly.

content: Quote from: wilfred on July 23, 2014, 08:29:19 amNope, brand new.QuoteNope, different slot.I believe it is an intermittent software bug caused by inserting the memory card when the camcorder is on.Almost all the time it works no problem, but very occasionally if you do this then you can encounter the bug where it then fails to record anything onto the card after it is inserted. It works and displays everything just as if you are recording (e.g. red record light, timers etc), but nothing gets written to the card. Or at least nothing that can be easily recovered.The camera will display empty clips on the playback screen.QuoteThere is a technical reason, this is not the first time I have lost a days worth of shooting to this bug. I'm pretty sure it's not a hardware fault.QuoteNot if you suspect it's software fault, in that case that's a very silly thing to do.The new G30 model is claimed to fix many nasty bugs inherent in the previous G10 and G20 models.

I've been using the 2nd slot for some time now.QuoteThat was entirely reasonable to assume that.I believe the first memory slot has developed a bad contact, and that to be expected after thousands of insertions.The 2nd slot was virtually unused, and I'm fairly certain this is an intermittent firmware bug at fault here. The HF G10 is known as having some bugs which Canon never fixed. They never released a new firmware update for it since it was released.

content: The G30/XA25 looks really good.Some new feature I don't have that would be very useful- wider angle lens- more zoom (not so handy, but ok)- 3.5" screen instead of 3" screen, with increased resolution (super important for a technical blogger looking at boards etc through the lens)- Much improved touch screen. The G10 is a dog to use, lots of pressure required.- WiFi that allows manual control from a smart phone. The G10 only allows rudimentary control via remote- MP4 recording (also simultaneous) which allows faster direct upload for non-edited stuff- Bigger sensor for lower light work. For those not aware, a typical office environmentislow light.- 50P. Meh, might come in handy for action stuff.- A real size shoe mountBut it's now over a year old? Maybe a new one in the works?This seems like a comprehensive review:http://tubeshooter.co.uk/2013/06/22/preview-canon-xa20-xa25-hf-g30/

Ironically though I think I'm better at this gig because of this limitation.

content: I was all set to get a locally available cheap consumer Panasonic camera, but I found that they cripple the ones sold in NZ (and therefore I assume AU as well) into only recording at 25 and 50 FPS, no 30 or 60Hz option.Their justification for this is based on some arcane analog TV format being 50Hz, but it makes video that judders massively when dropped into a 60Hz project.Only solution was to spring for a "pro" model at 10x the price.I again ended up getting a camera off amazon thru a reshipper because it was way cheaper than anything locally.

If you do decide on it, i'd recommend asking someone to buy it for you from US to get the 4k@30fps version.. the EU version only does 4k@25fps. 30fps is already a bit bad if you're doing lots of motion in 4k.

But that means my B-Roll camera will be 25P.Given that even with the canon G30 option I have to ditch all my batteries, I guess the option of getting two new cameras and selling both my current ones isn't off the table.

I meant to say you have a ring around the lens to which you can attach additional macro lens or filters (if the built in ones aren't good enough) and so on.

I highly doubt its software fault, it is writing to the card after all, just not all the bits are correct.But at this point I suspect Dave is too deep in the new toy phase to back down, plus spooked about the idea of wasting half a day with this particular camera.

content: Long time browser - first time poster.The Canon XA series cameras are great. We have the XA10 at work for backup and small shoots that don't require taking out our Sony production cameras. My gripe with the XA10 is the touch screen is terrible and clunky. I've read that Canon has improved the touch screen on the XA20/25 but I have not tried it. A complaint that I have seen in a few places with the XA20/25 is that the battery release button is blocked when using certain tripod plates. With those aside we have gotten great looking video out of the XA10 and once it's set up to our liking it is very easy to use. With that said I can only imagine that the new models are going to output an even better looking image than the XA10.The biggest plus to the the XA series are the dedicated XLR audio inputs and phantom power. This will give you better selection of mics to use, manual control of the audio levels, and better sound as the use higher quality preamps.^Just my 2 cents.

For a complex piece of equipment like a camera you need to know (as much as possible) that it's going to work. Same with test gear, sure if it's only being used once in a while maybe test before use.Dave's primary bit of gear for the blog is his camera gear. He uses it more than his test gear. Unless this is a known problem with an easy fix a professional needs to shelve it or sell it and get on with a replacement. Even though it sounds harsh gear is changed all the time for many reasons (other than failure). It's not a big deal when your livelihood depends on it.

content: There are some cameras with internal storage but they most always have removable storage options (XA10 for example) - just have to remember to set the camera to record to the right drive. I do remember some consumer Sony Handycams that had HDDs and they had high failure rates. One of the biggest issues with recording to internal memory besides running out of memory is with the post workflow as you either have to copy the footage over to the SD drive, which can takes more time, or you have to take your camera over to the computer and plug it in.

content: Cannon is good, but they too fall prey to "why is that a problem?" syndrome. Classic example is their pretend it doesn't exist attitude to the DSLR image writing problem that existed for years and across several generations of cameras. Put simply, if you took a picture or a series of pictures and happened to shut the camera off while they were still writing to storage.... *POOF* They were gone. Other camera makers simply put the logic in to keep that circuit alive until the buffer was flushed, but Cannon let it go on for quite awhile. I am sure the DSLR write is fixed now, but I would not make any assumption about them fixing a product flaw in newer generations anymore.Trust is like a cold glass of water in the desert, quickly gone and hard to get.

content: If the issue is lost work from failures, then you need to step up to a more professional camera IMHO. One that is built for more continuous use and has an SDI out so you can send the output to something like a Black Magic Hyperdeck. Actually I would use the Hyperdeck as the main recording device with a nice SSD you can swap to your computer for direct use and leave the cards in the camera unless you need to recover a failed recording on the Hyperdeck. I really think a jump up to a $4000USD camera plus the Hyperdeck would get rid of many headaches and make the workflow so much nicer, especially if the camera has true XLR inputs.If you make your living doing video, then buying the right tool is just the smart thing to do.Which camera in particular? Well, there are so many to choose from now. Find the one with the right features you want, lens range, light capability, storage media type, and with SDI out.

But they dropped 4k recording and they disabled XAVC-S and it uses only the plain standard AVCHD (xavc-s would retain more quality from that sensor at same bitrate) and some audio modes are gone.And it comes with the ligher NP-FV50 battery which typically lasts for 1h - 1 1/2h of recording time.$500 cheaper though.

I'd be taking step backwards.2) The hard drives might add noticeable noise to the audio3) Taking out an SD card and popping it in my machine is easier and more flexible than bringing the camera to the PC and sticking in a USB cable.QuoteI've done about 700 videos with SD cards without a single such issue, barring this bug which is not related to the contact.I've also done a ton of videos with waterproof HD camcorders in harsh physical conditions without a single issue either.How about those millions of GoPros?I know you love hard drives because you design them for a living, but really, for basic camcorder internal use they should relegated to the history bin.They still have a niche for external recording boxes for massive amounts of data of course. But other than that SD cards killed them long ago and rightly so.

content: My CX410VE came with the NP-FV50 as well, I can record about 90-110 minutes on battery, with lcd screen on. A bit less if I'm moving around a lot (the balanced optical stabilisation with servos and all that uses a bit of "juice". But that big ass sensor on the new cameras probably uses more power.There's a NP-FV70 battery which lasts about 2 and a half - 3 hours and a NP-FV100 that can do up to 5-6 hours. The NP-FV100 battery is about $90-100 on Sony's website.

CABAChttps://en.wikipedia.org/wiki/Context-adaptive_binary_arithmetic_codingI'm not saying this is the case, but it most likely will be. Would have to do a comparison what canon cameras use.

I have a camcorder with Sd card. bump it while filing and you have corrupted files. the problem is the edge wiping contact of SD cards.I've done about 700 videos with SD cards without a single such issue, barring this bug which is not related to the contact.I've also done a ton of videos with waterproof HD camcorders in harsh physical conditions without a single issue either.How about those millions of GoPros? i have a sony actioncam (the latest and greatest that records in micro sd). Nothing but trouble. When mounted on the car and hitting a pothole the image file is sometimes corrupted. If the card is not exactly the right speed you get buffer overruns .Nothing beats a factory installed memory as it will always be the correct speed and format. I had to try at least 3 different cards to get one that could mainatain 1920x1080 at fastest rate for longer than 5 minutes. Most of them would overrun. And then there is fragmentation of the flash.I don't like those things. Nothing but trouble. Far less hassle to have a turnkey system with the correct memory factory installed.

content: Dave:I think you need to look a bit more into my suggestion. My suggested workflow is no more complicated than, not that much anyway, than what you do now. The difference is you pull out an SSD instead of an SD and put it into your computer drive dock. The Black Magic Hyperdrive starts and stops automatically with the camera and gives yu a much faster workflow right from the beginning. It can also be mounted directly on the tripod or another plate with the camera.OK, I do understand that right now you fire up a small handheld camcorder and that is it. The added size and weight of what I am talking about sounds like it is not to your liking. I also understand that. I am just trying to propose a higher end setup that gives you the best of both worlds. Connect the Hyperdrive when you can't be let down, or don't connect it when you want a light hand held setup.Yes the price of all of the higher end equipment is a bit of a slap in the face, but that's the cost of stepping up to the next level. My kit probably cost me in the neighborhood of $20,000USD and more but you don't need to spend that. A really major step up in work flow speed and reliability will cost you around $5K, I think. If you just want a camera without bugs then good luck, especially with Canon. They really seem to give no care to what they fix or don't fix.

content: Quote from: bwat on July 24, 2014, 07:08:27 amMain difference is in persistence of mapping between physical spot in space/time continuum where your data is stored, and a virtual sector number.Hard drives/ raw flash/ CompactFlash / SmartMedia / I think also xD - all of those map more or less 1:1, and let You, the user, choose physical spot on the medium. Hard drives over time gained ability to remap bad sectors, but they do it only when encountering unrecoverable error, and you can still get physical address from the Service Area (g-list, p-list).Secure Digital / Memory Stick / SSD - those ones keep virtual mapping that is dynamic and constantly changing, they also run housekeeping jobs in the background sorting/shuffling data around, erasing continuous regions to optimize write speed etc. Youm never know where your data is stored exactly (unless you know particular flash controller used and its mapping algorithm).Back to Daves camera. SD card spec does have CRC32, but vendors notoriously ignore it or simply dont implement in the first place. This can cause a situation where camera thinks its writing data when one of the 4 data pins is randomly glitched. Then you have bugs in fat implementations in embedded firmware, all camera vendors want you to format card inside the camera, because firmware might not be able to deal with fragmentation, unusual filesystem layout etc.Edit: they are also rather adamant about deleting files ONLY inside camera. Card that was inserted into a pc, files deleted there, and inserted back into camera is _NOT GUARANTEED TO WORK RELIABLY_ because of said filesystem handling bugs. This might be what Dave is experiencing.Yes, this is stupid in 2014, 27 years into Fat lifecycle. But so is over 10000 global variables in Toyota car computer controlling fly-by-wire throttle.

content: One reason to consider sticking with Canon is if you plan to use the new camera and at the same time capturing additional B-Roll with the older Canon as their images will be similar in look, tone, and coloring. The only other brand that comes close to the "Canon Look" is JVC - but their current offerings aren't impressive.If you are fine with another brand then I suggest the Panasonic AG-AC90AEN (50Hz version). It seems to have most of what you are looking for - simultaneous recording to both SD slots, a high res LCD at 1,152 k dot, audio input mixing, a decently wide lens at 2.84mm which on this camera is equal to a 35mm format equivalent of 29.8mm and the ability to use macro adapters. You may be able to use your current macro lenses by using step-up/down rings but that will require some experimentation. The only drawback is the power consumption is quite high at 12.9W, however they include a 5,400mAh battery that is stated to give up to 6 hours of recording time. Realistically with lots of zooming and using the best recording quality you are looking at around 5 hours. From experience with Panasonic's professional cameras their battery life is actually decent. I know it's not a big deal for you but it also has XLR inputs and a removable shotgun mic holder. Personally, I really like the look of Panasonic's images.As far as life-cycle goes for camera models it varies between a year and two years. Most professional cameras will run for 2 years before they announce the next version. The camera I mentioned above was just released so I wouldn't expect a new model for 2 years. As for the Canon's that are 16 months old you would have to wait for the industry trade shows that take place in February through April before any new cameras will be announced and then several months beyond that before they start shipping. So realistically you could be waiting another year.It is frustrating researching cameras and pro AV gear. We go through it every May when we are told within a few days that we need to spend the remaining budget.

content: Modern florescent lighting uses electronic ballast, rather than magnetic, so the 50/60hz flicker is no more on new fixtures. It's more like 30,000Hz anymore, old setups notwithstanding, of course.I'm glad I got new fixtures, though. LOTS brighter, AND less electricity usage... win/win.

Even the LED panels Dave is using show up on measurements regularly.I have banned all florescent electronic ballasts arround my working bench. Constant current driven LEDs are much less nosy (both electrical and optical).

content: So if you are considering a monitor, how about a monitor recorder?Like this:In case you have not watched any "Film Riot" it's entertaining / funny and educational when it comes to film. The quality of the show is amazing (professional) when you consider it's done in the guys home most of the time. Highly recommended.

content: Quote from: EEVblog on July 29, 2014, 09:04:55 amFor the content you make and what you do there isn't any real advantage to going to a 30fps/60fps system. If you were doing more motion intensive videos then you could switch over for slightly better motion handling with the 5/10 gain in fps.As for the YouTube encoder converting 50/25 PAL material to 30fps - There was a known error that caused 50p/i material to be wrongfully converted to 30fps since YouTube doesn't handle higher fps natively. Not sure if that was ever fixed or if YouTube has since allowed 50/60p footage but I doubt it since 50/60 fps footage is overkill for standard web video. So far YouTube has preserved all of my footage at the original frame rate - I shoot mostly at 24p.Any opinion on the camera I mentioned last week?

content: Quote from: Rigby on July 29, 2014, 04:35:58 pmShielding would help, but is not always possible, especially for Dave who has to be able to film everything.Having a fluorescent tube with an electronic ballast near a scope (~ 50cm) can show a signal in the range of 1V on the screen. Compared to other EMI sources, a nearby electronic ballast produces a really strong signal. The most practical solution is to simply avoid it and go for some (non pwm driven) led lighting.

content: Quote from: RyanAMT on July 29, 2014, 07:06:17 pmThe AG-AC90A looks pretty neat, but ultimately the Canon is as good or better for much less cost, albeit slightly less versatile.And I didn't see a real dB audio meter on it either. But I liked it's ability to delete the last clip. Seems like it has the same last scene preview limitation as the Canon.The Canon is more compact, has a wider angle, more zoom, WiFi control, cheaper, and is familiar. I can almost buy two Canons for the price of the Panasonic.

content: Quote from: Eliminateur on July 30, 2014, 12:26:40 pmWell, yeah, there's that!In the end I figured that regardless of which camera, I should be formatting the card in-camera before each shoot (as I currently try to do to), and should be using the backup dual SD card recording option.So in the end I wasn't really trying to fix the big as such, I simply got duped by the extra functionality of a new modelBut considering that I'll be running a dual camera setup more often with the extra bench, a new cam was a good investment either way.

content: Quote from: wilfred on July 30, 2014, 12:44:21 pmYes it does, just like many other cameras do.QuoteIt's got nothing to do with the size, it's the convenience. I can take the SD card out back to the PC at any time and check footage and audio in detail without interrupting my setup. Can't do that with built in memory unless you dick around with big full HD HDMI monitors and headphones on your rig etc.

content: Quote from: EEVblog on July 30, 2014, 12:31:35 pmI kind of figured it might be a bit overkill. It has a db meter, although it doesn't display a numeric value just two little lines in the sweet spot of either -20 to -12 for digital or -12 to 0 for analog.The last scene preview is something that camera manufacturers never seem to care too much about in regards to making it more useful. The only camera that I've used where they got it right is our Sony PMW200 - you only have to press the Thumbnail button and you can play any clip on the card or you can press another button to go back to back to the live view all without having to put the camera into an entirely different mode through some sort of a reboot.Going with what is familiar is almost always the best option with video gear.

content: OK, got it.My VU meter is digital then obviously. 0dB is hits clipping. I've got the auto attenuator switched on which allows me to get closer to the 0dB clipping level on the meter without worrying about big transients kicking into clipping. Although it's still possible to clip if you drive it fast enough to beat the auto attenuator.I usually aim for about -6dB on the meter. My Canon shows a green sweet spot marker at -12dB, but I never operate below for regular work I ensure my audio is at least hitting that point.BTW, there is no "off" for the Auto Attenuator feature, only a fixed "ON" attenuator.

The Canon G30 just seems nicer and more professional to use in many regards.The G30 is really quite awesome.Not sure if I'll keep the Sony or resell it, need to play with it a bit more.No idea about the bug yet, as that was always a rare intermittent thing.Full G30 review shot and coming soon.I now have 4 decent blogging cams:

content: Hey Dave.I had a similar problem with my 7 years old Pentax Optio E30 that also didn't write the files properly. Turned out that the fault was a SD card (512Mb - as old as the camera itself, over 7000 pictures-videos) that was simply getting old. Got new 8Gb card for 5 euros and the camera started to work again. Although the shutter button is starting to fail now. One problem ends with another...
