To create frames from video  ffmpeg ffmpeg -i  video  test thumb 04d jpg -hide banner  Optional  remove frames you don t want in output video  more accurate than trimming video with -ss  amp  -t  Then create video from image frames eg   ffmpeg ffmpeg -framerate 30 -start number 56 -i test thumb 04d jpg -vf format yuv420p test output mp4

See the Create a video slideshow from images     FFmpeg     If your video does not show the frames correctly If you encounter problems  such as the first image is skipped or only shows for one frame  then use the fps video filter instead of -r for the output framerate   ffmpeg -r 1 5 -i img 03d png -c v libx264 -vf fps 25 -pix fmt yuv420p out mp4      Alternatively the format video filter can be added to the filter chain to replace -pix fmt yuv420p like  fps 25 format yuv420p   The advantage of this method is that you can control which filter goes first   ffmpeg -r 1 5 -i img 03d png -c v libx264 -vf  fps 25 format yuv420p  out mp4   I tested below parameters  it worked for me   e  ffmpeg ffmpeg exe  -r 1 5 -start number 0 -i  E  images 01 padlock 3d png  -c v libx264 -vf  fps 25 format yuv420p  e  out mp4   below parameters also worked but it always skips the first image   e  ffmpeg ffmpeg exe  -r 1 5 -start number 0 -i  E  images 01 padlock 3d png  -c v libx264 -r 30 -pix fmt yuv420p e  out mp4   making a video from images placed in different folders  First  add image paths to imagepaths txt like below     this is a comment details https   trac ffmpeg org wiki Concatenate  file  E  images png images   3d jpg  file  E  images jpg images   3d jpg    Sample usage as follows    h  ffmpeg ffmpeg exe  -y -r 1 5 -f concat -safe 0 -i  E  images imagepaths txt  -c v libx264 -vf  fps 25 format yuv420p   e  out mp4    -safe 0 parameter prevents Unsafe file name error   Related links  FFmpeg making a video from images placed in different folders  FFMPEG An Intermediate Guide image sequence  Concatenate     FFmpeg
