At first I tried to run it on Leap 15.5, but its glibc 2.31 was too old. On Tumbleweed-Slowroll the cin-aom-38_svt.AppImage started ok.
Thanks for the test. So it is useless to create appimage from one rolling because they only work on other rolling.
But unhappily it was a bit even slower on my machine than the previous aom. And continued playback Video with aspect ratio 4:3 and scratch sound on the Audio. smpte170m colors seems for me to be for NTSC, and not for PAL video. Rendering took 0:41:08, almost 6 times the clip duration
I too have a lot of confusion about how CinGG treats colors in specific cases. See the notions on Kernel.org if they can help you: https://www.kernel.org/doc/html/latest/userspace-api/media/v4l/colorspaces-d... In the meantime, I'll post the ffprobes from my tests (project's size 1920x1080; 16:9. source1: DNxHR, 1080p; source2: h264, 2160p; source3: VP9, 640x480): AOM_3.8.0: $ ffprobe -hide_banner test_aom_38.webm [libdav1d @ 0x5619aeb26140] libdav1d 1.3.0 Input #0, matroska,webm, from 'test_aom_38.webm': Metadata: ENCODER : Lavf60.16.100 Duration: 00:01:12.17, start: 0.000000, bitrate: 1266 kb/s Stream #0:0: Video: av1 (Main), yuv420p(pc, bt2020nc/unknown/unknown, progressive), 1920x1080, SAR 1:1 DAR 16:9, 24 fps, 24 tbr, 1k tbn Metadata: DURATION : 00:01:12.128000000 Stream #0:1(ita): Audio: vorbis, 48000 Hz, stereo, fltp Metadata: DURATION : 00:01:12.170000000 [libdav1d @ 0x5619aeb62400] libdav1d 1.3.0 (12.5 fps; 10.9 MB,) AOM-SVT: $ ffprobe -hide_banner test_aom_svt.webm [libdav1d @ 0x55b740a0a140] libdav1d 1.3.0 Input #0, matroska,webm, from 'test_aom_svt.webm': Metadata: ENCODER : Lavf60.16.100 Duration: 00:01:12.17, start: 0.000000, bitrate: 1369 kb/s Stream #0:0: Video: av1 (Main), yuv420p(pc, bt2020nc/unknown/unknown, progressive), 1920x1080, SAR 1:1 DAR 16:9, 24 fps, 24 tbr, 1k tbn Metadata: DURATION : 00:01:12.128000000 Stream #0:1(ita): Audio: vorbis, 48000 Hz, stereo, fltp Metadata: DURATION : 00:01:12.170000000 [libdav1d @ 0x55b740a46400] libdav1d 1.3.0 (11.8 MB; 58 fps) The video, but especially the audio, seem to me to be of slightly lower quality than the original sources.
If SVT-AV1 1.8.0 rendering is possible with cin-aom-38_svt.AppImage, where do you select this? Among the webm presets should also appear av1-svt.webm, the profile created by Andrew; see image:
