Can't Read File

I tried loading this file:
Complete name                            : E:\scratch\Newyear\00000000.avi

Display aspect ratio                     : 16:9
Frame rate                               : 23.976 fps

Stream size                              : 77.7 MiB (0%)
Interleave, duration                     : 42 ms (1.00 video frame)

and got a big green image that would not work at all.  Oddly it took no time to read, so it didn't actually go through the file?
I repackaged it as MKV (using mkvmerge) and tried again.  Now it showed the loading progress bar and took a few seconds, but the result was nearly the same:  a green frame, and playing it gave a fraction of a second of audio, though the correct time length was shown.

I'm running Windows x64.  I tried 2.6.1 and 2.6.7.

What I Really Want is to save from Resolve(Free) to an uncompressed file that I can then feed to Avidemux to filter and encode.  So if anyone can tell me what would be a better way to save the DaVinci Resolve output as, let me know.


Just something to try:
What happens if you change the 4CC code from HDYC to UYVY?

Could use fourcc changer (http://www.fourcc.org/changer/).


The command-line ffmpeg can read it.
So what should I tell it to output?  I'm wondering if it's the 10bit that Avidemux doesn't like?  And what format/codec specifies uncompressed frames?

I just wanted to see if changing the 4CC metadata would avoid that big green picture you get in avidemux. 
Why not try it?

Hopefully others can help with your aims.

The question about codec specifications for uncompressed frames seems to be an oxymoron.
Uncompressed frames are not subjected to any compression method.
The 4CC for uncompressed video relates to the pixel storage format / color space model.
Codecs are programs that let you compress and decompress to some compression standard like mpeg-4.
