For sure. You downgraded the video to half the size, then blew it back up again, converted the audio, set the apple mov headers, and spit that sucker out as an mp4 with probably half the resolution in pixel density but hey - it played.
I would try it again without the pix_fmt flag, the vf flag (and string). No idea what -level 3.0 is as it’s not in the docs anywhere (hallucination?). The video filter scaling definitely needs to go if you want it to be as close to the original resolution.
Cool part is, it worked. Even with a bad flag or two, ffmpeg said “Hold my beer”
- teraflop 1y ago> You downgraded the video to half the size, then blew it back up again No, that's not what that command does. It performs a single rescaling that resizes the video dimensions to the next lower multiple of 2. e.g. it will resize an 801x601 pixel video to 800x600. If the video size is already an even number of pixels, it's a no-op and doesn't lose any detail. If the video size isn't already even, then the rescaling is necessary because H.264 doesn't support odd dimensions. > No idea what -level 3.0 is as it’s not in the docs anywhere (hallucination?).
