Even if it would, the success would greatly depend on the particular source video and thus cause a lot of confusion. Many sources like digital television insert very few IDR frames into their streams, almost all keyframes are just seek points which doesn't allow a clean cut.Īvidemux doesn't support such "smart copy". The second point is very difficult to achieve (it is very difficult to find a matching encoder configuration), the first one depends on the particular sort of stream you've got to edit. At least the frames starting from the cut point and up to before the next keyframe. On the other hand, if the cut point is frame accurate, and the cut point is not a keyframe, there will always be quality loss.
However, the cut point will never be frame accurate.

the keyframe following the cut point is an IDR and.Ģ.we can re-encode the part of the GOP after the cut point with exactly the same decoder parameter sets (the information which is supplied along the compressed image data and tells the decoder how to interpret this information) as used by the source video. LosslessCut cuts video based on keyframes. The fundamental feasibility of such a feature requires thatġ. This is very fast and easy, it takes only a few seconds and I've. But only so-called IDR (instantaneous decoder refresh) keyframes allow to make a clean cut in a sense that no single frame following such a keyframe may depend on any frame preceding the IDR frame in stream order (you should know that in modern codecs like H.264 and HEVC, the display order of decoded pictures may be different from their order in the data stream). With Losslesscut you can combine videos into one, provided they have the same resolution, framerate and codec, without re-encoding. frames which allow to start playback without any broken, pixelated pictures spoiling the show. Make a selection with the A and B controls at the bottom of the video view. All keyframes can act as a seek point, i.e. Lossless cut a video file Open the video in Avidemux through File - Open. Anyway, merging multiple clips from one video would be a nice feature too. In general, this is impossible without re-encoding at least a part of the video due to the very nature of video compression. Original question was about merging multiple videos.

Is there any software that can cut video between the keyframes without rendering the video.
