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.

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. The fundamental feasibility of such a feature requires thatġ. Great for rough processing of large video files taken from a video camera, GoPro, drone, etc. 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). LosslessCut is a simple, cross platform video editor for lossless trimming / cutting of videos. frames which allow to start playback without any broken, pixelated pictures spoiling the show. All keyframes can act as a seek point, i.e. In general, this is impossible without re-encoding at least a part of the video due to the very nature of video compression. Lossless cut is a GUI (Graphic User Interface) to FFMPEG - the command line compression backbone that is used everywhere, including YouTube. Is there any software that can cut video between the keyframes without rendering the video. Quote from: erkan_iii on March 30, 2020, 02:32:54 PM 'LosslessCut is based on Chromium and uses the HTML5 video player, not all ffmpeg supported formats will be supported directly' this means it does not support X265/HEVC or fairly common containers like.
