Thank you for this great image.

It would be nice to have the same edit feature as in VDR

copy/paste for vdr manual:

* Editing a Recording

While in Replay mode, the following keys can be used to manipulate editing
marks:

- 0 Toggles an editing mark. If the mark indicator shows a red triangle,
the current mark is deleted. Otherwise a new mark is set at the
current position.
- 4, 6 Move an editing mark back and forward. You need to first jump to
an editing mark for this to work.
- 7, 9 Jump back and forward between editing marks. Replay goes into still
mode after jumping to a mark.
- 8 Positions replay at a point 3 seconds before the current or next
"start" mark and starts replay.
- 2 Start the actual cutting process.

Editing marks are represented by black, vertical lines in the progress display.
A small black triangle at the top of the mark means that this is a "start"
mark, and a triangle at the bottom means that this is an "end" mark.
The cutting process will save all video data between "start" and "end" marks
into a new file (the original recording remains untouched). The new file will
have the same name as the original recording, preceded with a '%' character
(imagine the '%' somehow looking like a pair of scissors ;-). Red bars in the
progress display indicate which video sequences will be saved by the cutting
process.

The video sequences to be saved by the cutting process are determined by an
"even/odd" algorithm. This means that every odd numbered editing mark (i.e.
1, 3, 5,...) represents a "start" mark, while every even numbered mark (2, 4,
6,...) is an "end" mark. Inserting or toggling a mark on or off automatically
adjusts the sequence to the right side of that mark.

Use the keys described under "Replay Control" to position to, e.g., the
beginning and end of commercial breaks and press the '0' key to set the
necessary editing marks. After that you may want to use the '7' and '9'
keys to jump to each mark and maybe use the '4' and '6' keys to fine tune
them. Once all marks are in place, press '2' to start the actual cutting
process, which will run as a background process. When replaying the edited
version of the recording you can use the '8' key to jump to a point just
before the next cut and have a look at the resulting sequence.

Currently editing marks can only be set at I-frames, which typically is
every 12th frame. So editing can be done with a resolution of roughly half
a second. A "start" mark marks the first frame of a resulting video
sequence, and an "end" mark marks the last frame of that sequence.

An edited recording (indicated by the '%' character) will never be deleted
automatically in case the disk runs full (no matter what "lifetime" it has).
