Then, I randomly play the trimmed videos on my Kodi HTPC to create my own custom pseudo music video channel that is free from ads and overly long intros/outros.

Sometimes, the videos have really long intros and outros that I want to trim off. I like using this method when I download music videos from YouTube. Check to make sure it's the way you wanted it.Open the newly trimmed video in your favorite media player.Give the new video a unique name, so you don't overwrite the original.

I suppose you can choose a different 'Output Format', but for compatibility's sake, I like MP4v2 which most modern devices can play.

Under 'Output Format' choose 'MP4v2 Muxer'.

Make sure 'Audio Output' is set to 'Copy'.

Make sure 'Video Output' is set to 'Copy'.

Press 'Delete' and it will remove everything between Marker A and Marker B which would be the end of the video.

This time, press the 'Set Marker A' button and Avidemux will automatically 'Set Marker B' to the end of the video.

Again, use the 'Previous Intra Frame' button and 'Next Intra Frame' button to find an I‑frame to cut on.

To trim the end, scrub the video near where you want to make the next cut.

Press 'Delete' and it will remove everything between Marker A and Marker B which would be the beginning of the video.

Press the 'Set Marker B' button and Avidemux will automatically 'Set Marker A' to the beginning of the video.

Use the 'Previous Intra Frame' button and 'Next Intra Frame' button to find an I‑frame to cut on.

To trim the beginning, scrub the video near where you want to make the initial cut.
