Hi,
I know this thread is rally old, but I finally got passable results
with:
ffmpeg -f image2 -r 60 -i frame%d.png -mbd rd -trellis 2 -cmp 2 -subcmp 2
-pass 1/2 -r 59 video.mpg
Thanks all,
Ian
It may help that SDL has a wav audio driver that writes all sound
output to an uncompressed .wav. Unfortunately it will take some magic to
get it synced with the video you've assembled.

hi ya,
if you have spare cpu/memory bandwidth, then screen casting software
may be easier.
There's some good free ones here:

How does it work?

You should be able to make a set of images into a movie but the image
quality is not gonna be perfect (because once you go to a video file
then it's compressed. there's no getting around that.)
You could just display the frames yourself, at a specific frame rate,
or you could just automate your

Righto--that's
You can use ffmpeg. A quick sample line I found is this:
ffmpeg -f image2 -i frame%d.jpg video.mpg
Explore the ffmpeg options and you will find the way to include an
audio file for sound.

Alrighty, I've got my first (ever) ffmpeg movie sorta working.
I'm using the command:
ffmpeg -f image2 -i frame%d.png -r 59 video.mpg
As you'll see, I've added a framerate thingie as best as I understand it.
However, the resultant movie is much slower than the original program (which

I figured out I have to set the input file's framerate too:
ffmpeg -f image2 -r 60 -i frame%d.png -r 59 video.mpg
The image speed looks perfect now.
Now, I need to figure out how to add sound to the movie. In my program,
there are several sounds that are played at different times. As I
