Output file #0 does not contain any stream I think one problem is that "%4" in a bat file is threated as argument number four. png format and convert to it automatically.Ĭode: H:\Q>D:\Multimedia\ffmpeg\bin\ffmpeg.exe 00025.MTS -ss 00:00:00 -ss 00:00:10 -fr png at the end of the filename, ffmpeg will understand you want the. in the above example, i am extracting 24 frames, im_0001 im_0002 im_0003. The -frames:v n (n) is the how many frames you want to extract from that -ss position and onward, up to the end of the video.
The %4d is the length of the padding for zeros sequentually, or else the sorting won't work correctly when opening/viewing the images in a folder or video timeline. if you exclude the -ss (or -t which is the duration or length you want to extract) you will only get the first frame and no more. for general extracting, i would say it doesn't matter.
this affects the accuracy (between i-frames) and/or speed. there are advantanges of when to use -ss. in the above example, i use two -ss commands.
