FFMPEG best quality image extraction possible
13 janvier 2021, par sci_12I would like to extract pictures (png) out of a video for a 3D-modelling task. They should be in the best possible quality.
Video is : 1920x1080, 60 fps, 24 bit depth, mp4 .. I have now tried different approaches and feel like I should go with :

ffmpeg -i input.mp4 -vf "select=eq(pict_type\,I)" -vsync vfr thumb%04d.png -hide_banner

but I am not sure if I could get even a higher quality out. Zooming in will be really important.
Thanks for every help.
