Editing Recordings
Editing a recording allows you to specify a cut list, which will cause MythTV to automatically skip over some areas of the recording during playback. This allows you to edit out the areas before, after, and within the recorded program. Common areas to remove are parts of an unrelated earlier or later programme, and news or advertising breaks. Once you have created a cut list, you may also choose to transcode the recording to remove the cut areas from the recording file.

Editing without the MENU key
The above instructions show how to use the editor through the MENU key (by default, M), an approach that allows anyone to easily find the desired actions, even without spending time learning the editor interface. However, if you frequently edit recordings, you will find that nearly all actions can be performed more easily without using the MENU key.
- To delete an existing cut:
- Using SELECT:
- Move to any frame within the cut (for example, by using PREVCUT (by default, PgUp) and/or NEXTCUT (by default, PgDown)).
- Press SELECT (by default, Return, Enter, or Space) to bring up a menu.
- Select
Delete This Cut
- Using DELETE:
- Move to any frame within the cut (for example, by using PREVCUT (by default, PgUp) and/or NEXTCUT (by default, PgDown)).
- Press DELETE (by default, D).
- Using SELECT:
- To move the start or end of a cut:
- Extending a cut:
- Move to the frame where the cut start or end should be.
- Press SELECT (by default, Return, Enter, or Space) to add a new cut marker.
- Move to any frame within the cut (for example, by using PREVCUT (by default, PgUp) and/or NEXTCUT (by default, PgDown)).
- Press SELECT (by default, Return, Enter, or Space) to extend the cut from the previously-placed marker.
- Shortening a cut:
- Move to the frame where the cut start or end should be.
- Press SELECT (by default, Return, Enter, or Space) to bring up a menu.
- Select
Move Start of Cut Here
orMove End of Cut Here
.
- Extending a cut:
- To join two adjacent cuts:
- Move to any frame between the cuts (for example, by using PREVCUT (by default, PgUp) and/or NEXTCUT (by default, PgDown)), then LEFT (by default, Left arrow) or RIGHT (by default, Right arrow) to move off the marker and into the space between the cuts.
- Press DELETE (by default, D).
- The editor makes adding new cuts extremely easy. Therefore, it's often easier to remove "wrong" cuts than to move the ends of the cuts (see "To delete an existing cut", at the top of this section).
