create thumbnails from big movies with FFmpeg takes too long

Question

I\'m using this shell command to make thumbnail from VIDEO_FILE from 123 second and save it to THUMBNAIL_FILE.

ffmpeg -i VIDEO_FILE  -r 1 -ss 123 -f image2 THUMB         


        

Answer 1

it has happened to me also, changing the argument order fixes this problem. tested on a 1.4GB 90 minute mp4 video - took about 1-2 seconds. before that it took MINUTES...

try this:

ffmpeg -ss 123 -i "VIDEO_FILE" "THUMBNAIL_FILE" -r 1 -vframes 1 -an -vcodec mjpeg
