Editing Recordings
Explained
●
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. 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 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 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).
