I need to transcode video created using the Camstudio Lossless Codec into the QuickTime RLE format in order to get it to work with some other software.

What methods can I use to convert the video? I seem to have trouble finding software that will encode my video like this.

http://www.ffmpeg.org/ffmpeg-all.html#Video-and-Audio-file-format-conversion

ffmpeg -i input.mp4 -codec copy -c:v qtrle output.mov

That will copy any audio, subtitle, or other non-video streams, and transcode video with the specified video codec. For supported options specific to qtrle,
ffmpeg -h encoder=qtrle

  • What about the other way? I have FFMPEG and I try copy a MOV file which is encoded in qtrle and I get: Could not find tag for codec qtrle in stream #0, codec not currently supported in container. – Royi Mar 14 '17 at 11:16
  • If this works, the -codec copy parameter (which copies a stream without re-encoding it) is, I believe, overridden by the -c:v qtrle parameter, which re-encodes the stream (is lossy). In other words the -codec copy parameter does nothing and can be removed. – r_alex_hall Mar 30 '18 at 7:35
  • @r_alex_hall: -c copy applies to audio and subtitle streams, too. So it's like -c:a copy -c:s copy -c:v qtrle The ffmpeg man page uses this as an example: ffmpeg -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUT will copy all streams (-map 0), except transcode the 2nd video and the 138th audio. The default for most containers is not copy for audio, it's some specific codec. – Peter Cordes Mar 30 '18 at 19:33
