Camera board • Re: camera module 3 slow video at beginning

Thanks for responding gordon77 and your help on this.
I ran the conversion command you provided and it did fix the timing issue. There are some inconsistencies that are listed during conversion. It lists fps as being 25, rather than 30 and puts up a warning about timestamps in the video being unset:

Input #0, h264, from 'video.h264':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: h264 (High), yuv420p(tv, bt709, progressive), 1920x1080, 25 fps, 60 tbr, 1200k tbn
Stream mapping:
Stream #0:0 -> #0:0 (copy)
Output #0, mp4, to 'video.mp4':
Metadata:
encoder : Lavf61.7.100
Stream #0:0: Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709, progressive), 1920x1080, q=2-31, 25 fps, 60 tbr, 1200k tbn
Press [q] to stop, [?] for help

[out#0/mp4 @ 0x5598afa3a0] video:17530KiB audio:0KiB subtitle:0KiB other streams:0KiB global headers:0KiB muxing overhead: 0.022712%
frame= 287 fps=0.0 q=-1.0 Lsize= 17534KiB time=N/A bitrate=N/A speed=N/A


Is there something in the camera2 module that I can use to correct the timestamps to begin with?
