Hi Ted! Thanks for your reply and pointing me in the right direction!
Now i use os.system('ffmpeg -i ' + workdir2 + '%d.jpg -r 120 -vcodec mpeg4 -qscale 1 -y -filter:v '" setpts=0.23*PTS"' ' + destinationdir + videofile) thats ffmpeg -i /mnt/ramdisk3g/workdir/%d.jpg -r 120 -vcodec mpeg4 -qsale 1 -y -filter:v " setpts=0.23*PTS"'' /mnt/ramdisk/mp4/ And the result is this https://drive.google.com/file/d/1acRm7vWwJAXz1jEU66nuD7Db9mrtPuz-/view?usp=sharing In workdir i have multiplied every image 6 times with python counter loop and total number of files are 1374 when there is only 229 Iam pretty happy to results now. Not sure how that minterpolate works but i will try use that too. Still images i use are from Raspberry Pi + Meteotux PI program and they are 120s stacked images. You can check more about that from https://www.meteotuxpi.com Thanks again!
