Any other programme is able to make raw to dng?
When i open the raw2dng.exe (win), it popped a second and closed. What is the reason of it?

Drop your raw file directly on the raw2dng file; it'll create .dng files.  You have some reading to do brother..

Any hints on how to do this?
Thanks,
Shawn

Well, I've pulled down a free hex editor (HxD) and replaced what I believed to be the footer from footage recorded just after the "big" one.  Only problem is I can only extract the same number of dng files that I can with the "new" raw file - meaning the new raw file was very short just to grab the footer.
Short of recording a really long video and grabbing it's footer, what else can I do?

I did a replace insert beginning with the line that looked like this (and everything after it):
@bYÈ($b†È:$L,,(LÂ

It already runs till your card fills on some resolutions.

PS. If you fill the card and your footer is missing, shoot a quick shot at the same settings and then copy pasta the footer from that file to the end of the huge file.

Any hints on how to do this?

And this is not changeable at all? If not, we have to live with it, if yes it makes sense to make it work.

For now I'm leaving the FPS override option on and doing a 103% time stretch in post.  It's at least close to good enough.

When I aligned the two files (audio) in After effects it seems that there were added spaces of time and/or gaps in the recorded audio.

I noticed this as well.

with the audi problem, you should give plural eyes a try. sure, it s not a perfect solution, but works pretty well

If I had a good reference track I'd already be using pluraleyes to sync it.  The problem is when you're not using an external audio device and just the onboard audio.  It's either off in the beginning, the middle, or the end.  I've had longer clips where the audio was "ahead" in the beginning, ok in the middle, and behind towards the end.

@Shield
this is the command to convert tiff sequence and wav to ProRes 422 with ffmpeg. Will do some more tests now if the Audio is in Sync.

Sounds like you have a separate step in your workflow - I import the dng sequence directly into AE.  Let me know if your time is synched up.

i have tried to record a clip with audio enabled, the wav was then recorded onto the sd card, the filename was like the raw filename, e.g. m00001.wav
so, i have tied to open the wav with several programs, none worked?
can someone please explain how the audio recording works when record with raw?
thx.

You have to put it on the timeline of your editor and remove the extra hours of data; shrink it down to be the same size as your video clip.  Or run it through an audio editor like Soundforge, Adobe Audition, or the free command line ffmpeg.  But it should at least have the same filename as your raw file.  Synching is a pain in the rear though.

Well, I've basically been up all night trying to get the audio sync working for the 5d3.  After much trial and error, I've found that about a 103% "time stretch" does a really great job.  It's between 103-104%; probably 103.2 would be damn near perfect.  Make sure you whack the end of the audio file off first before you do the stretch.
I tested this on a 4 minute clip and it's off by maybe a nanosecond all the way at the end.
Keep in mind this is with FPS override ENABLED, and set to 24p.  If I disable this, the video gets waaaaay ahead of the audio and then "catches up" and I lose even more sleep.    Hope this helps someone who shoots without an external recorder.  Workflow = Adobe after effects CS6.

You can trim the furthest point of the wav file in your composition by hitting the "alt" and ] keys (will remove everything to the right).

Also, if you're using a modern multiple core CPU, be sure to adjust your memory & processor settings in Adobe After effects.  Like a moron I was using the default and render times took forever - adjusted it so it uses 8 "cpus" now and it's flying.  Well, relatively speaking, of course.

Ctrl-M is the shortcut key to add a project to the render queue.

All for now.

Ted said the internal audio is off by up to 4 frames if I recall correctly, that's on the MK2 but it's probably the same with the MK3.

We're not talking 4 frames though on the 5d3 - I'm talking like 1 full second.

EDIT: I just see: ffmpeg to avi is in sync
ffmpeg -i %6d.tiff -i M0000000.WAV -acodec copy test.avi
but prores_kostya isn't...

EDIT 2: Forget the Audio thing, i think i solved it. Probably messed up some flags. This is working:
ffmpeg -i %6d.tiff -r 24 -i M0000000.WAV -async 1 -vsync 0 -vcodec prores_kostya -profile:v 3 -qscale:v 6 -vendor ap10 -pix_fmt yuv422p10le -r 24 -threads 4 -strict -2 -y Audio.mov

I don't understand either of these commands - what is %dt.tiff, and why output it to a .mov file?

Another issue i have is Audio. I try since several hours to get the Recorded Wav from the 5D III in Sync with Video in ffmpeg. No matter what i set on camera 23.976/24.001 Frames or in ffmpeg vsync, async, audio offset, 23.976, 24 frames - the Audio always goes out of sync pretty badly even after 7-8 sec. It appears the sound is faster than the Video.
So my questions (to start with):

Has anyone in any software being able to Sync Audio (recorded in Cam to Wav) with Raw footage?
If so, where and what and how, you know?

is 5D III Wav recorded in 48000 Rate? Any way to set this in Camera?

I've noticed the Audio Length is 00:00:14.76 while the Video length is 00:00:14.50 (according to ffmpeg)...

And another one - Bitrate setting for 5d III H.264 is not working? Nothing happens with h264.ini (or how it's called..)

thanks

I too am having trouble with the onboard recorded wav file synching up.  I realize someone replied to this talking about a 12 minute external recorder, but I'm talking about the internal audio that I need for reference, or when I don't shoot with an external recorder.
Will dig into this as well, and I'll try your ffmpeg settings.
According to Mediainfo, the recorded onboard mono .wav file is:
Audio
Format                                   : PCM
Format settings, Endianness              : Little
Bit rate mode                            : Constant
Bit rate                                 : 768 Kbps
Channel(s)                               : 1 channel
Sampling rate                            : 48.0 KHz
Bit depth                                : 16 bits
Stream size                              : 4.39 MiB (100%)

For reference, the audio recorded with a non-hacked 5d3 is:
Audio
ID                                       : 2
Format                                   : PCM
Format settings, Endianness              : Little
Bit rate mode                            : Constant
Bit rate                                 : 1 536 Kbps
Channel(s)                               : 2 channels
Channel positions                        : Front: L R
Sampling rate                            : 48.0 KHz
Bit depth                                : 16 bits
Delay relative to video                  : 42ms


Don't know if the "delay relative to video" means anything or not in the ML world, and I'm sure it's something they're aware of.

Just thought I'd share my experiences so far; if this helps out anyone that's great.
The following assumes you're using a 5d3 + Adobe after effects for importing.

Tip 1 - If you use a Sigma or Tamron lens, you can fix the vignette in the Adobe Raw importer if you select a Canon lens.  If you pick the actual lens you have it may not work (my Tamron 24-70 didn't).

Tip 2 - In Adobe after effects, you can import all of your DNG sequences and queue them up for rendering - just make sure you have 1 movie and at least one "composition"  Meaning if you drag/drop one movie to a composition and hit "add to render queue" and then try to add another one, it'll only render the LAST movie you added to that composition.  I manually create new compositions and get them all in the render queue so I don't have to sit and wait for each one.  If you know of a better way, I'm all ears.  So if I'm doing 6 raw sequences I'll have 12 files - 6 imported DNG sequences, 6 .wav files, and 6 compositions.  One per "movie".  The only reason I mention this is Adobe Premiere works a little differently; you can swap files out and keep adding to a render queue and it'll render correctly.

Tip 3 - Get a USB3 reader - it makes a WORLD of difference copying .raw files back over.  I picked one up tonight along with a PCIx - USB 3 4 port device and it's about 5x as fast copying files back over.

Tip 4 - If you want to record 1920x1080 with audio, insert an SD card in your other slot and it will automatically (assuming you have changed it from the default "beep").

That is all for now.

Same here... I had received 2 64gb Komputerbay 1000x cards this week and only 1 worked in my 5d3.  The other worked only on the pc but not in the 5d3.  Returning that one and getting a replacement.  Has already returned the 128gb due to slow write speeds.  These cards are hit and miss.  The good 64gb card however is pretty fast and 1080p works well.

Did you buy them on Amazon or ebay?

Mine worked fine straight out of the box. All I can offer is maybe install the card in the camera and tether it to the pc?

Even when tethered it says "unable to use card".  I did a full low level format, same thing.  Now doing a full exFAT format in Windows 7 64.  Not looking good.

Just got in a 64GB Komputerbay 1000x card.  Works fine in a PC but the 5d3 cannot see or format the card.  Doing a low level format now and going to re-format with exFat (windows shows it already WAS exFat).  Anyone have this problem?

Thanks - had no idea where to put it.

One "bummer" about this lens is the vignetting wide open.  Once stopped down to about F/4 you're fine if you don't like the vignette.  My workflow with the 5d3 + raw has been Adobe After effects - I noticed that when you import the first DNG file and go to the "lens profile" tab and select the correct Tamron lens, the vignette slider has no effect.

However, if you select "Canon" as the lens model (I chose 24-70 2.8 as the Canon lens) you can then get rid of your vignette, even at F/2.8.

Great news!  Not sure if this was thread worthy but I just had to share.

This was posted in the "Raw video on 5DMK2" thread, but I thought it was well worth mentioning in case it hasn't been seen by all.

If you have RAW selected as your photo type and record, say you get 100 frames at any given resolution and fps.

If you then change your photo settings to disable RAW and shoot only Small JPG, you'll get MANY more frames of RAW video.

It seems like there was 2-3 more *'s worth of buffer when I did this.

Benchmarks are the same, so it appears it just opens up some more buffer room.

In my tests, I went from 150-170 frames to 290 just like that!

So the resultant dng files are the same size too?  Have you tried jpg small?  I'm about to.

[audio does not get recorded]

I had already checked that.  There are 2 repeatable scenarios which cause audio issues in H.264 video recording...

FPS overide is NOT enabled in either scenario...

Scenario 1
- Enable raw video mode with "Sync beep" option.
- Record raw video
- Disable raw video option
- Record H264 video... audio does not get recorded

Scenario 2
- Enable raw video mode with "Separate WAV" option.
- Record raw video
- Disable raw video option
- Record H264 video... audio gets recorded but is distorted (sped up like chimpmunk)
- Record H264 video again... audio gets recorded normally from now on

I hope this helps.

I've just been removing the CF with ML on it and shooting H264 on my SD card for now.  When I don't want to do amazing raw video, that is.

Well I just shot 32 gigs of raw movies in 3 files.  I immediately switched over to the SD card (my wav drive) and snapped a raw pic.]
Examining the exif info, the camera temperature was 43C.

I've seen it warmer than that shooting outdoors without any hacks with the standard firmware.  I'm not worried about overheating this 5d3 at all.

+1

My tamron 24-70 vc is now 24-70 2.8 and 120-350 2.8!!!

I thought this was really a 3x crop?  So wouldn't your 24-70 (I have that lens too; great lens!) be 72-210?

Well guys I was skeptical until I tried this for myself - it's brilliant!

I am using the 32GB 1000x Lexar CF card - has anyone formatted the card for exFAT and enabled the greater than 4GB recording and gotten it to work?  What's the longest continual recording that anyone has gotten in which raw2dng will still work?

*Edit* To answer my own question, apparently the raw2dng.exe for Windows doesn't work with files >4GB.  Only works in Linux so far from what I've read.

Also, I couldn't get the audio to work until I stuck a SD card in the other slot, then I was fine.
