I have a 30 second video for testing.

Steps on what I did:
1. Cut the first 10 seconds at an I-Frame of the video in Copy mode and save.
2. Cut to the 10 second to 20 second mark (in I-Frames) and encode Video Output: Mpeg4 AVC (x264) with the same bitrate as the original 30 second video.
3. Cut the last 10 seconds at an I-Frame of the video in Copy mode and save.

When I appended everything, the video was saved successfully. I played the first 10 seconds of the video and it was fine, after reaching to the 2nd appended video, there were green blocks in my vlc player. Everything was a mess but the audio is fine playing after the 10second mark.

I researched that there was this partial mode in Filters but it's not here anymore in the lastest avidemux. But to save time in encoding, I thought of just encoding the part of the video that needed the image and copy mode the rest so it will be faster.
