Config Dialog: Keyframes

MMP provides excellent audio and video editing facilities

• for the user, editing is really fast and non-fiddly
• you can edit and export the finished product without even stopping playback
• editing is "lossless" and doesn't require that the exported audio/video be re-encoded
• in effect, you are doing a copy/paste from your original file to the edited file
• consequently, the quality of the exported file is identical to the original

• press Ctrl-[E] to open the Audio & Video Timeline Editor
• for general editing purposes, the "rough cut" approach is often enough
• for videos, if you want to be more specific about where an included segment starts, you should use Keyframes

Keyframes

• to toggle keyframe processing on/off, use [F]
• keyframe processing is now so fast that it is viable to leave keyframe processing turned on by default in the Config Dialog
• with keyframes turned on, the vertical cursor will change color to indicate how accurate a cut will be if you start a segment at the cursor position
• the vertical cursor coincides with the currently viewed position of the video file
• a segment will always contain at least the video content you require, give or take a few frames - keyframes are not a factor in where segments end
• whether or not a segment might also include some content just prior to where you want the segment to start will be indicated by the vertical cursor:

• a white cursor (rough cut) indicates that the exported segment will start at least 1.0 seconds prior to where your segment starts
• a yellow cursor (good cut) indicates that the exported segment will start 0.5 seconds to 1.0 seconds prior to where your segment starts
• a purple cursor (best cut) indicates that the exported segment will start 0.0 to 0.5 seconds prior to where you segment starts
