I need a simple script that will batch trim a specified number of frames off the beginning and/or end of each video clip in a folder and then reserve each file. This will mostly likely need to use FFmpeg. This needs to run natively on a Mac and be fast. For example, it should not take longer than 5 minutes to complete a folder of 200 4k .mov video files on a 4.2 GHz iMac. After the frames are trimmed off, each video file needs to be saved without losing any quality or bitrate amount of the original video files, or dropping any frames.
Hi. I can write this script easy. But i should to tell that speed depend only from ffmpeg. There are no magic and cant be adjusted. Hope to working together.
