Hello there, It's possible. For a single image every 240 frames, assuming a frame rate of 60, you can exploit the select filter as shown: ffmpeg -i input -filter:v 'select=not(mod(n\,240))' image%02d.png To use time-based selection which will also include the first frame: ffmpeg -i input -filter:v 'select=isnan(prev_selected_t)+gte(t-prev_selected_t\,4),setpts=N/(60*TB)' image%02d.png For documentation, see the select and the setpts filters: 1. Select: http://ffmpeg.org/ffmpeg-filters.html#select_002c-aselect 2. setpts filter: http://ffmpeg.org/ffmpeg-filters.html#asetpts_002c-setpts _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
