1. High-Speed mode can only be used with AVI and MP4 files. (We will support MKV, FLV, TS, MPG files in the future.)
2. Some AVI/MP4 files which have an unsupported codec are not able to use the High-Speed mode.
3. If you can't use [High-speed mode], you have to use [Encoding mode].
- To cut a WMV file, you'd better convert the whole video file to an AVI file format through the [Encoding mode], and then cut the AVI file through the [High-speed] mode. It will allow you to cut WMV files without the audio/video sync problem.
1. Video files of which the index is damaged
2. Video files without a keyframe or index
3. Video files of which the index is not available for analysis
1. A file without video (not playable due to no video information or codec support)
(File without audio information available for playback and conversion).
Bandicam can precisely cut videos by "Frame" while keeping the original video quality in High-Speed mode.
However, some MP4 video files can only be cut by "Keyframe" instead of "Frame" in High-Speed mode.
- If you use High-Speed mode and you see the error message above, the start time of this file may change because of a codec issue.
- If you use the free version of Bandicut, you can only use Encoding mode in the above case.
- Frame: A frame is a single shot of a series of still transparent pictures that form a video. (A frame contains partial information of a still scene.)
- Keyframe: A video file has a limited number of keyframes - not every frame is a keyframe. A keyframe is a frame used to indicate the beginning or end of a change made to the signal. (A keyframe contains full information of a still scene.)
(If there is a 30 FPS video, it will have 30 "Frames" and may have 1~5 (?) "Keyframes" per second.)
