What video editor do Linux users of mencoder recommend?
I have LIVES. For clips of more than about 1000 frames it is unbearably
slow.
A fast simple editor that can only delete segments, and encode the
result, would be useful.
mencoder can already do this, but an interactive front-end that shows
the first and last frames of the region to be deleted, and allows to
browse frames as easily as LIVES does, would be helpful.
For those who don't have LIVES, here is a description of the simple
functionality described above.
LIVES has two regions where it displays frames. The left one is the
first frame of a selection. The right one is the last frame of a
selection. When a clip is loaded, the left one is the first frame of
the clip and the right one is the last frame of the clip. Below each
region is a widget displaying the frame number. One can adjust the
frame number either by typing a new one into it, by selecting up- or
down-arrow parts of the widget, or by dragging one or the other end of a
slider that extends across the LIVES window below both regions.
After one selects a region, LIVES allows one to do many things with it,
but the interesting one for this simple job is simply to delete it. At
that instant, LIVES deletes the selection, which can take an hour on a
dual-core 3.0 GHz computer with 2GB of memory for a clip of only 20
minutes duration. It also renumbers the frames, which is unhandy if one
wants to repeat the editing session with slightly different requirements.
It would be better to batch the "delete" requests and apply them
together, preferably by invoking "mencoder" with an "edl" file listing
the frame regions to be deleted, when an "apply" action is specified.
Perhaps "apply" should be coupled to "encode."
Ideally, this should be coupled to mencoder by a modification of
mencoder that allows to specify skip regions in the "edl" file using
either frame numbers or seconds.
"undo" and "redo" features would be nice, but the bare-bones
functionality of deleting unwanted parts of clips doesn't really need this.
