If I was able to cut with external audio, I wouldn't need to save the mpeg2 video. I think this is the simplest way as far as I know. lets say the video is 100 frames long, if I use Trim(0,49) the video will be 50 frames long, but audio will still be 100 frames long and the encoded video will play for 100 frames. add the already cut audio as external track and encode them together
load mpeg2 video thru avisynth script without audio save copy of mpeg2 video and mp2 audio track as audio file load the original TS material with its original audio and cut them together If you pass 0 for lastframe it means 'end of clip.' A negative value of lastframe returns the frames from firstframe to firstframe + (- lastframe-1). Trim trims a video clip so that it includes only the frames firstframe through lastframe.The audio is similarly trimmed so that it stays synchronized. Really cant imagine a scenario which needs to cut a video material to an already existed audio which is already in desired cut state before that somehow and need to add as an external track to video after cut it.Īt the moment I have to do more sessions to achieve the desired result with avisynth. Trim (clip, int firstframe, int lastframe, bool padaudio). It would be way better if avidemux was able to handle external audio track as a muxed one. I think its more realistic scenario that people would like to cut video and audio in same time together, and don't have an already cut audio which needs video part to adjust to with the same cut points as audio. AvsP provides a trim selection editor to simplify this task.

However, it can get a bit unwieldy when you are trying to trim several sections of video (for example, cutting out commercials from a tv recording). Therefore, please always mux an external audio track into the video first, save the video, load the result, then perform any editing steps. Trimming video is fairly straightforward in AviSynth with the Trim() command. What should happen? Should the external audio track get a gap? There is a good reason not to have one: imagine, you delete a portion of video loaded in Avidemux first, add an external audio track second, then you undo the deletion. I told it to start at frame 1000 (in other words, trim out everything before that frame) and go until the end of the file - 0 is a special value for the Trim filter which means 'the last frame of the clip. It takes two arguments, a start frame, and an end frame. External audio tracks are special as they are by nature independent from video tracks and thus don't have the segment handling logic which is available for internal audio tracks. Trim takes the current stream and trims bits off the ends. script selection is Trim(10, 100) ++ Trim(120, 200).Reverse(), insert selection 10-100 and 120-200 Fixed: The video slider was highlighted after closing the trim editor and a bookmark was selected.
