--- Comment #3 from Jens <jens-bugs.kde....@spamfreemail.de> ---
I was just about to report quite the same wishlist item.
Use case:
I have 5 videos of people singing the same song. I want to mix these to create
a chorus. But these people are just *so* slightly
a) out of time (sometimes faster, sometimes slower, one makes dramatic pauses
where they don't belong),
b) out of pitch, actually singing in different keys, and
c) generally not singing at the same speed.
Right now, I have to cut the tracks into multiple pieces and play these at
different pitch-compensated speeds. This is a lot of manual work, especially
because Kdenlive (current, 21.07.20, nightly Flatbak build) does not like
changing speeds in the same track, and sometimes loses video. Different bug.)
Also the sound sometimes stutters at the cut positions.
I would LOVE to create a keyframeable "speed curve" over each track, which is
optionally pitch compensated, so that I can slow down the track in some parts,
and speed it up in some others - and even stop it completely (still frame) when
one singer misses a pause and continues singing.
This should happen independantly of what original FPS the tracks were recorded
at. "100% speed" is always set to the FPS which the track originally had.
Do you think this is feasible? I'm willing to discuss and help brainstorm this,
since I think it's a major feature.
Thanks!
