First make sure you have FFmpeg installed. Follow this guide if you haven't already:
Running the CLI
To create a sample of a file using FFmpeg, use the following command:
ffmpeg -ss 00:00:0 -i "C:\Transcode\input.mkv" -t 00:00:30 -map 0:v? -map 0:a? -map 0:s? -map 0:d? -c copy "C:\Transcode\output.mkv"
You can set the start time of the sample using the
-ss flag. Set the duration of the sample using the
-t flag. For example, to have a sample which starts at the 11 second mark and runs for 43 seconds, use the following:
ffmpeg -ss 00:00:11 -i "C:\Transcode\input.mkv" -t 00:00:43 -map 0:v? -map 0:a? -map 0:s? -map 0:d? -c copy "C:\Transcode\output.mkv"
You can automate this process using Tdarr.
