Infoseite // DNxHD with ffmpeg or mencoder under Ubuntu



Frage von saemjamin:


Love slashCAM community

I do not like disturbing yes, but since I am now the entire World Wide Web, it seems to me to have searchable, in vain, but now I need a little attention.

My problem is that I have videos in h264 format, which are located in the. Mov container that will convert into a verlusstfreies format encode / in order to process it can.

And I'm s.DNxHD.

My question is: DNxHD under Ubuntu at all possible? And / or is there perhaps alternatives under Ubuntu?

Maybe someone knows next.

Lg

PS: Here's a clue:

Antwort von prime:

Yes is determined, have recently tested as synonymous AVCHD material in DNxHD (in mov) endowed with the 'normal' ffmpeg (win32 binary, SVN r24103).

Possibly. you need to compile it * just * only yourself if you do not find usable binary.

Antwort von pailes:

Yes goes, I've already made synonymous, but I have ffmpeg synonymous compiled from source, but was not a problem. However, I had the famous QuickTime Gamma problem, that is, the colors were faded with me not like the AVCHD clip, it worked somehow.

Antwort von saemjamin:

strange, so this is the command that I type:

ffmpeg-i-vcodec <input_file> DNxHD-b-<bitrate> s.output.mov

out and then comes an error:

"Video parameters incompatible with DNxHD"

as loud as your ffmpeg command?

Antwort von prime:

DNxHD encoding to go only with certain resolutions / bit rate combinations. See:
http://www.itbroadcastanddigitalcinema.com/ffmpeg_howto.html

is on the Page
Quote: - <bitrate> Can take the following values: 36Mb, 60Mb, 90Mb, 120MB, 185Mb (please refer to the following table).
For the command should look like-b-b 36M not 36Mb or the like.
