Transcode YUV 4:2:2 to uncompressed 10 bit .mov
on Jun 17, 2011 at 4:15:51 pm

Hi guys,

I've been given a .avi with the codec of yuv 4:2:2 and I really need to try and code it out as high res possible to work with inside of FCP.

So far I've been able to get ffmpegx to get it out but only to a .mov with .h264. I'm then transcoding this to work with in FCP as pro res 422HQ - which essentially I've been using as an offline.

Obviously I've got a step that is losing me massive quality in there. Does anyone know how to transcode the YUV in to 10 bit uncompressed? I've done a fair bit of research and haven't come up with much.

Any help will be greatly appreciated.

Thanks in advance,

Lawrie

I think I ran into something like that last year.

the workaround was to open it on a pc and export as 10-bit uncompressed .mov using black magic's 10-bit pc version of their codec.

Chris,

Thanks for such a quick response. What programme did you use for this and do you know where the BM codec can be obtained?

Thanks,

Lawrie

Also, if you're not squeamish about using the terminal, then the command line version of FFMPEG will encode to 8-bit and 10-bit uncompressed quicktimes.

But aren't there some plug-ins that will let Quicktime Player read these AVI files? Maybe I'm mis-remembering...

Hope this helps,

I did a google search on the codec and found a free pc codec.
there was no quicktime/mac version that I could find.

if you google the bm codec it should come up as well.

Doesn't MPEG streamclip open avi?

If not try perian + mpeg streamclip. Both free.

Hi guys,

Thanks for the ideas. Mpeg stream clip won't do it an pertain doesnt work either. Such an annoying codec.
As ffmpegx opens the file I wonder if anyone knows how I go about operating in the comand prompt to output to uncompressed 10 bit?

All other ideas, including how to get/use this illusive black magic codec are greatly appreciated.

Thanks,

Lawrie

[Lawrence Bowden] "I wonder if anyone knows how I go about operating in the comand prompt to output to uncompressed 10 bit?"

Google "os x ffmpeg install" to read up on how to install the command line version of ffmpeg .

The pro install of Quicktime Player on a PC will also write 10-bit uncompressed quicktimes. But if Quicktime Player on the PC won't open the AVI files, this isn't much help.

From what I recall, the BM, AJA and Apple 10-bit uncompressed codecs are all pretty much interchangeable, no?

Weird. I just opened an AVI in streamclip, but perhaps it's a different codec.

You can also use the free AJA uncompressed codec as well:

OK so after A LOT of pain I've got it working. For any one else who comes across this heres what to do...

Install ffmpeg by following these instructions:

It's all in the terminal but its not that scary really.

Put the video file you want to use in your "Home" folder.

in the terminal type the following...

ffmpeg -i .avi -acodec copy -vcodec copy .mov



replace the variables and the <,> symbols..

BOOM! Wish I had of read this post 5 days ago. I hope it helps someone in my situation.

Thanks to all that helped.

Cheers,

Lawrie

"FFmpeg" and "fmpegx" are quite diferent things.
