I've used VideoMach for most of my past stuff, and it lets you select frames
with different names, and apply a text overlay.

I usually use Format factory to convert to some other video format afterwards.

No guarantees, but they're what I use, free, and you give them a shot and see.

Yep, I still use that on occasion. I especially like it for spitting out all the
individual frames from a real-life video, to use as image_maps in a POV-Ray
animation, for whatever purpose.

For video editing and assembly, I've had very good results with AVIDEMUX (for
Windows). It's relatively easy to use, too. But like most free video
editors/assemblers out there, it has its own strange little quirks. I've managed
to work around most of them. When I can't, I load the video in VirtualDub first,
then re-save it with NO compression as a giant-sized .avi file, then import it
into Avidemux for final work (and transcoding to an .mp4 file.) Doing the final
editing this way is a breeze, because VirtualDub outputs its video as all
keyframes (by default, it seems.) So frame-by-frame edits are painless.

Avidemux is great for putting together POV-Ray animations too.

I use ffmpeg for extraction too. :)

"from 1999-12-08.mp2, starting at the 4.5 second mark, extract 3.75 
seconds of video as vidE*.png. 0 pad the frame number to 5 places"

ffmpeg -ss 00:04.5 -t 00:03.75 -i /MyVideo/Balaska199/1999-12-08.mp2 
vidE-%05d.png		# DA dancing 9shls famroom

Thanks for all your suggestions and ideas, I really appreciate it!

I found a program called OpenShot (Open Source) which can import the pngs
directly into a timeline editor and export to mp4.

And, as suspected, result was MUCH better:

(Now I just gotta figure out how to avoid the "snap" that occurs between each
scene)

Ok, I have to admit VideoMach was an even better suggestion than OpenShot.

Really easy to adjust each frame's delay.

Thanks!

Getting there... scenes are roughly where I want them now. Got some jagged lines
appearing in this version, but I will try to tweak it a bit.

Also... I need to do something about that water mark saying "unregistered
version"...

I think you are talking about a filler between the animation scene files. One
way to do this is to use ffmpeg to loop a still image for a certain number of
frames (e.g. 1 sec = 25).
e.g. for a couple of 3 second fillers, using the last frame of each scene..
$ ffmpeg  -loop 1 -i stillimg1.png -r 25  -frames 75 scene1a.mp4
$ ffmpeg  -loop 1 -i stillimg2.png -r 25  -frames 75 scene2a.mp4

then
$ cat filelist.txt
scene1.mp4
scene1a.mp4
scene2.mp4
scene2a.mp4
scene3.mp4

That's EXACTLY what I mean and need.
Thanks a lot!
