Yes, that's exactly my finding too. And I fixed the mediadata Atom manually in the Hex editor and added the missing meta data at the end (moov box). Now it opens:

attempted repair 24fps-maybe.mov
(as promised yesterday)

Jay, thanks for your technical specifications - without it I could have never gotten it to actually load. However, in my programs (Quicktime, VLC and TMPEG Enc.) it still doesn't play back any content (just as if it didn't have the codec). Could someone please check in Premiere, Cineform, Vegas and Virtual Dub again? Also, could someone send me a 10 sec file right from the camera so I can give it the perfect meta information?


Well, I will try to get mine down again. Btw, a crazy but possibly constructive idea I wanted to share with you. What about keeping the timebase as it is but freezing all camera processes for 1/180th of a second, 30 times a second just after sensor readout. Some kind of "thread.sleep" or "delay" function. You get a 30p file that would play back real time when slowed to 25p.

Thomas I will check it with with the tools I use at the commercial production facility I am senior editor at (After Effects, FCP, Avid and MPEG streamclip). Not the ones you requested but valid apps to give it a go.

Attempted Repair Clip
 

OK. It does open...and all apps report a H.264, 1920 x 1080, 4:27 sec., 30 FPS clip.
BUT, it comes up black in After Effects , Quicktime Pro , FCP and in MPEG streamclip
it opens up green. It does play back, but only the reported colors are evident.

Yes, exactly my findings. Shame, I thought better players may do the trick. There are two possibilities:

1) the media data Atom is completely broken (nothing can be done then, as far as I know)

2) my meta data (moov box) is wrong. I don't own a 5DII, so I used the meta header from a supposedly "raw" 5DII file instead. I am not certain it really is raw, unmodified 5DII output.

Once I get a real, 10 - 12 sec long/ ca. 40 mb large original 5DII file, I can use that instead. I think this repair option is still promising.

I tried 3 times to send you a 45.5 mb 5D file (10 sec,) but the site kept giving me a fatal error message after a 15 min. upload. Sorry. Maybe someone else will have better luck

Hi Tom,

thanks so much for your efforts. Attached a little tool I coded to extract just the Moov Box from a .mov so it becomes small enough to simply email. Please upload the moov box file here or send it to me via mail.

In case we will have to fix files on a regular basis to continue the framerate experiments I can just expand the tool to do whatever we need.

Thomas. I am on a Mac Pro. I unzipped the Moov box extractor. How am I supposed to utilize it? When I try to run the exe file it says "The contents of the file Moov Box Extractor.exe can not be extracted with this program." How do I tell it to extract the H.264 file. Its a little obtuse. Tried several approaches to use it, but none worked. Is this meant for the PC?

Tom,

sorry. I never thought about Mac OS actually. The little application was written in Microsoft C# (part of the .Net framework) and needs Windows.

Thanks for trying. I think we will leave it here. If someone else wants to provide a different Moov Box for me to try, I'll give it another go. For now I think we have to conclude Tramm's settings must have created a totally corrupt file.

Let's hope Tramm finds some non-corrupting framerate settings inside his wizard hat one day :D

Thomas

Thomas,
Sounds good.

Found an original 10 second 5D II clip on the web and used its meta data to fix Tramms file.

However, I get a black picture and just loud noise on the audio track. I think there is nothing more to fix. Unfortunately.
