Quote from: conhelio on October 03, 2020, 04:30:20 PMFrom my limited understanding of video editing until now, is it correct that encoding mode might be simpler, but it would take considerably more time to produce the final result, especially if you are dealing with long videos (2 hours, 900 MB mp4 file)? (edited, forgot to mention that marker B must be set before saving) If you get errors: please don't hesitate to ask. Please note: this frame doesn't need to be a keyframe, but it is not a keyframe, the real last frame in the output may be slightly different, depending on stream properties. Navigate to the keyframe where you would like the video to end. Navigate to the keyframe where you would like to start the output.ġ2.
If you need more cuts within the video, repeat Steps 4-8 accordingly.ġ0. If you get a warning that the stream is using non-IDR frames as keyframes TAKE IT VERY SERIOUSLY, don't override it and try to find a combination of start and end point which doesn't trigger this warning.ĩ. Repeat Step 4 to find the suitable keyframe to place the end point of the cut. Drag the navigation slider approximately to the location where you would like to start to cut away a piece of the video, refine the position with UP and DOWN arrows (both the navigation slider and the UP and DOWN arrow keys seek to keyframes – the type of frames where cut points in case of cutting in copy mode must be placed).Ħ. Is the video displayed in the right orientation? If it is on the side or upside-down, press the button to open the configuration dialog for the output format and set Rotation to the right angle.Ĥ. Make sure that "MP4 Muxer" is selected as output format and both video codec and audio codec are set to "Copy".ģ. It doesn't matter much which one you use unless you need VapourSynth support which is possible only with native builds – if you don't know what VapourSynth is, you don't need to care, just grab the newest.Ģ.
The most important thing: please use the latest Avidemux nightly, it has got a lot of important fixes, not present in the last release.Īt the moment of writing the 64-bit build from the former directory is more recent. I'll go ahead and provide a walk-through for the case of cutting in copy mode (re-encoding is simpler).Ġ.
