I needed a single ffmpeg command that will trim a video by 8 frames from beginning and 8 frames from the end of the video. Is there a way to do this. I'm on windows 10

If there is a single command to get this done it will really speed up my work, current option is to take it to premiere and trim and then export.

If you know the frame rate (to calculate the frame duration) you should be able to use following code, assuming 8 frames = 0.333s (the 24FPS video)

#!/usr/bin/env powershell

$inputFile="input.mp4"
$outputFile="output.mp4"
$trimSeconds=0.333 # frames / FPS


$videoDuration=ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 ${inputFile}
Write-Host videoDuration=${videoDuration}


$endPosition=(($videoDuration -as [double]) - ($trimSeconds -as [double])) -as [string]


ffmpeg -ss ${trimSeconds}s -to ${endPosition} -i "${inputFile}" -c:v copy -c:a copy ${outputFile}
