I don't know why it happens, but I know how to solve it, let's see if I can
explain it to you with a video.

I was trying to write a tutorial on speed changes in cinelerra ... but I am
encountering many errors with the speed line. Another problem is the one
that occurs if you paste or insert a clip in a track with the modified
speed, the result is what one expects. For example, in the video clip a
clip that lasts an exact minute on a track where the speed is at x2 and
this should cause the clip to last only 30 seconds, but no, it lasts 1
minute, but with the last frame frozen . And with the copy and paste of a
fragment the same thing happens, the clip lengthens, which makes the use of
the speed change line very puzzling.

It should be something simple to modify the speed, but in cinelerra it is
not. The only way I don't get errors in its result is by varying the speed
once the clip is inserted. It is very difficult to do a composition job in
this way, for the only thing that I see very optimal its use is once the
assembly is done, changing the speed.
