Image sequence interpolation, how?

So, you have an image for every single frame? And you only want to show
every 10th frame? Assuming that is what you want, try this: After
importing the image sequence. Drop the clip on the timeline and right click
(clip properties). Change the speed of the clip to a faster speed, and it
should make the clip much shorter... by skipping frames. Let me know how
that works.

Thanks,
-Jonathan

Dear Jonathan,

Thanks for your reply. What you propose is the opposite of what I'm trying to do.I want to add frames between images. Say I have a sequence of 10 pictures taken 10 seconds apart, I would like to have, say, 10 times more pictures in the movie by interpolation between each of the original 10 pictures.

I found a way to do that using yuvmotionfps.
http://jcornet.free.fr/linux/yuvmotionfps.html
It can be used to interpolate between frames using a command line such as:
/usr/bin/ffmpeg -i inputmovie.avi -f yuv4mpegpipe -vcodec pgmyuv - | yuvmotionfps -r 10:1 > outputmovie.yuv

All the best,

Ok, how about this. Same as before, but this time, after you import the
clip, change the speed to a slower speed, which will increase the length of
the clip. Effectively this will duplicate each frame many times, depending
on the slowness. Let me know if that works. Good luck!

Jonathan,

What you propose will produce an unpleasant saccadic output and therefore no improvement.

If yuvmotionfps code were included into OpenShot, it would probably be the only Linux/Open Source GUI software to do smooth frame interpolation.

Cheers,

-Thomas

Thomas,
I understand what you are wanting now. That feature does not exist in
OpenShot yet. Ideally, if this is a useful feature to alot of people, it
would be great if MLT integrated yuvmotionfps. You might pitch the idea to
the MLT developer mailing list. Just a thought. =)

Thanks!
-Jonathan
