Re: [FFmpeg-user] How to change FPS without re-render

Hello, you want to speed down 24fps to 23.976 fps? I always need to speed up 23.976fps material to 25fps (PAL): I use this videofilter: -vf "setpts=0.95904*PTS" -r 25 (23.976/25=0.95904) So maybe for your case this should work: (24/23.976=1.001001001001) -vf "setpts=1.001001001001*PTS" -r 23.9

Re: [FFmpeg-user] IMX50 NTSC framesize differs to the SMPTE 356M-2001 Standard - why?

yes, this happens because 50mbit/sec is not correct a max framesize of 208541 results in a bit rate of max 49.999840 mbit/sec, IIUC thats what the spec means by 50mbit/sec The spec actually says "Up to 50Mb/s" and "Up to 208541" that being the highest value that comes out below the the 50Mb/s. So

Very, very generally: No, this is the reason why a decoder is needed: Some applications produce an incorrect framesize for a given resolution. But in the case of a given application, the framesize has to be constant for a given resolution: If it is not, the file cannot be read. (And the framesiz

You can manually specify these settings to force them being set with these parameters: -color_primaries 5 -color_trc 1 -colorspace 6 What does not work as far as I know in ffmpeg is to actually get these settings from the source video, even if ffprobe detects them. Regards, Marton Thank
