Since zones don't work with 10-bit in x264, I decided to encode credits at lower bitrate and then join the two up but it's not working. I used the same encoding settings for both except the lower bitrate. Why can't I join them?

Marsia MarinerGuest
Two things:
-- (not so important) you forgot to define the pixel aspect ratio
-- (important) you forgot to use the --stitchable switch
Anyway: I could demux the elementary streams with ffmpeg and then I concatenated them with the olde and goode copy /b.
Then I remuxed the full-length video with mkvmerge. The new MKV file plays fine in both MPlayer and MPC-HC. -
Since zones don't work with 10-bit in x264
Why can't I join them?
The track number 0 from the file '... sav.mkv' can probably not be appended correctly to the track number 0 from the file ' ... SavCds.mkv': The codec's private data does not match (lengths: 43 and 44). Please make sure that the resulting file plays correctly the whole time. The author of this program will probably not give support for playback issues with the resulting file.
Code:--stitchable Don't optimize headers based on video content Ensures ability to recombine a segmented encode

Well, it didn't work for me with megui.
I've joined MKVs before this way without problems and I don't remember having to use --stichable, this is the first time I hear of such a setting.
what is the exact ffmpeg commandline?Code:ffmpeg -i "path to input .mkv" -vcodec copy -an -bsf:v h264_mp4toannexb "path to output .264"
Code:copy /b "path to part1.264" + "path to part2.264" + "path to part3.264" "path to output .264"

No scripts, just two command line calls.
1st call is the ffmpeg call meant to extract the raw .264 stream from a .mkv file. (see: https://www.ffmpeg.org/ffmpeg-all.html)
2nd script shows how to concatenate multiple raw streams (in my example case three) into on file raw .264 output file. If you only have two files use:
Code:copy /b "path to part1.264" + "path to part2.264" "path to output .264"
Code:copy /b "path to part1.264" + "path to part2.264" + "path to part3.264" + "path to part4.264" "path to output .264"

Wait a minute, this copy function is without ffmpeg?
So it's literally joining the files bit-by-bit?
I never knew H264 streams were that simple.
-> The proper solution is to use '--stitchable' using those two options is a workaround that should work assuming the streams are compatible and just the headers are 'off'.
