In case this also may be something for a CinGG "dv50.mov" preset: Long time ago, Renomath "Video with Linux, Workflow Resources" by Eric Olson, catched my interest (then unobtainable) DV50 when I read Hi8 Tape to DVD Video Workflow with Linux <https://renomath.org/video/linux/hi8/> /If you have a faster system you may want to consider capturing using the DV50 codec using a 4:2:2 color space. In order to do this, libng from the xawtv project needs to be patched to recognize the dv50 codec. Using dv50 as the capture codec really allows the Linux solution to surpass a stand-along DVD recorder. It is also possible to capture the video using ffmpeg or lavrec. / Cinelerra Version 4.x yuv4mpeg Patch <https://renomath.org/video/linux/cinelerra/> /Patch for dnxhd and dv50 Quicktime Input, which add dnxhd and dv50 input to Cinelerra. The advantage of dnxhd and dv50 over mjpeg is native support of 1080i, 4:2:2 chroma and greater encoding quality due to more flexible quantization and compression methods. ------- /While ffv1.mkv often is suggested as preservation master file for migrating analog VHS materials, a mezzanin file has also been suggested using File Wrapper: QuickTime (.mov), Video Stream: DV50, Audio Stream: 48Khz/16-bit PCM https://memoriav.ch/wp-content/uploads/2014/07/VARRFP.pdf ---- FFmpeg documentation has little documentation about dv50, which seemingly is less used: https://ffmpeg.org/ffmpeg.html#Main-options https://ffmpeg.org/pipermail/ffmpeg-user/2023-June/056548.html     -target type (output) Specify target file type (vcd, svcd, dvd, dv, *dv50*). type may be prefixed with *pal-*, ntsc- or film- to use the corresponding standard. All the format options (bitrate, codecs, buffer sizes) are then set automatically. The dv50 target is identical to the dv target except that the pixel format set is *yuv422p* for all three standards. ---------- I have tried to experiment with dv50 encoding via my ms2130 capture and v4l2 driver. First with just "c:v dvvideo -target dv50" which resulted in "25fps" and 50Mbps, but this caused jumping video images. I expect that issue was due to a unsupported frame rate. Some AI search later told me that DVCPRO50 (aka DV50) possibly optional could shoot in 50fps, so I tried to add "-r 50" in the output, which resulted in twice as big output file with 50fps as follows, but steady video images. ffmpeg -hide_banner -f v4l2 -i /dev/video0 -f alsa -ch_layout stereo -i hw:CARD=UHD,DEV=0 -codec:v dvvideo -b:v 50M -minrate 50M -maxrate 50M -target pal-dv50 -r 50 -c:a copy -t 10 -f mov DV50p+pcm.mov Input #0, video4linux2,v4l2, from '/dev/video0':   Duration: N/A, start: 174.116728, bitrate: 1990656 kb/s   Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 1920x1080, 1990656 kb/s, 60 fps, 60 tbr, 1000k tbn Input #1, alsa, from 'hw:CARD=UHD,DEV=0':   Duration: N/A, start: 1749543254.028464, bitrate: 1536 kb/s   Stream #1:0: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s [vost#0:0/dvvideo @ 0x55ecffd02f80] Multiple -r options specified for stream 0, only the last option '-r 50' will be used.
