FFMPEG wont keep the frame rate and duration
28 avril 2018, par macprodukshunzI have a .mov video that is 53.15 fps, I need to convert it with the same duration and frame rate to a mp4. When I do it it gives me a 60 fps mp4. How do I tell it to keep the same framerate ?
I tried :ffmpeg -i input.mov -r 53.15 output.mp4
That works with framerate but the duration changes and the output looses one second. I want the video to have the exact same basic attributes after conversion.
Im using the Terminal on macOS Sierra, if that matters.

Retrieving metadata from x264 ?
29 février 2012, par BlenderI am trying to exctract the meta data from x264-encoded video files. First priority is to map the IDR-frames structure. The work seams to be harder than expected and I am trying to find command line applications that I can control from my code.
Mp4box has an option "-dump-xml" or similar but I can't figure out how it works. Not much help available on the net on this option.
Anyone who can give me a hint on this or any other alternative ?
Thank you.
