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
qtrleand I get:Could not find tag for codec qtrle in stream #0, codec not currently supported in container. – Royi – 2017-03-14T11:16:06.833If this works, the
-codec copyparameter (which copies a stream without re-encoding it) is, I believe, overridden by the-c:v qtrleparameter, which re-encodes the stream (is lossy). In other words the-codec copyparameter does nothing and can be removed. – r_alex_hall – 2018-03-30T07:35:55.007@r_alex_hall:
-c copyapplies to audio and subtitle streams, too. So it's like-c:a copy -c:s copy -c:v qtrleThe ffmpeg man page uses this as an example:ffmpeg -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUTwill copy all streams (-map 0), except transcode the 2nd video and the 138th audio. The default for most containers is notcopyfor audio, it's some specific codec. – Peter Cordes – 2018-03-30T19:33:08.860
