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, preceeded 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. + * Programming the Timer Use the "Timer" menu to maintain your list of timer controlled recordings. |
