I found kdenlive to be excellent. I selected a VGA NTSC project, as it has
the same 4:3 ratio that my original flv file has, even though it is 1/3
larger. I put my 2 video files on the tracks 0 and 1, deleted track 2, which
moved the audio tracks up to position 2 and deleted the new audio track 3
(each audio track is mono or stereo, depending on the source -- mine was
stereo).
All I had to do was to position the video and audio tracks by dragging them
to the right or left a bit while playing them in the project monitor on the
right of the screen. It was a bit of fiddling to get the audio and video to
align 100% (I feel I succeeded sufficiently). Unfortunately, as I determined
from the audio track, my 2 video tracks have a 2-second gap and I was not
able to figure out how to put in a transition, so my video has a 2-second
black screen gap (audio continues uninterrupted), but this is almost not an
issue when viewing the final result.
Once I had made these adjustments, I selected render from the menu,
destination file rendering, flash 1000k 2-pass, force progressive scanning,
rescale to 480x360 (the size of my original flv videos), and finally pressed
render to file and it all worked super well!
This is definitely a very nice GUI for video editing... And a first for
Linux, I believe (years back, I fiddled with cinelerra and some others, to no
avail and lots of headaches and crashes), but this really works)!!!
Or use avidemux for simple re-encoding and splicing needs. ;)
Avidemux can only create avi files, am I correct? Also, it displays a weird
message about the source video file using B frames. It asks whether one wants
to use a different safe but inaccurate mode. One is required to answer yes or
no, but it is unclear from the phrasing of the question which method one is
saying yes or no to. When one answers either yes or no (I tried both),
another message appears, stating that no audio decoder is found and that
saving the file will generate a bad avi, but that audio saving will work
(despite there not being an audio decoder!), but video will presumably not
work. At some point it crashes no matter what you do.
