April 6, 2013 at 10:40 amOkay, thanks guys. That double %% did the trick and I also had to put path names in 8.3 format; e.g. “Program Files” became “Progra~1”.
I have some issues with output format/quality and cropping at the moment, but I’m sure I’ll get that sorted now I’m actually generating a movie.
Here’s the basic batch file entry I’m using at present:
ffmpeg -f image2 -r 24 -i C:\Progra~1\ffmpeg\frames\reel_1\frame-0%%05d.jpg -target pal-dvd movie.mpg
The -start_number option works, although I can’t find it mentioned anywhere. I was trying to find if there’s an equivalent -end_number option. I’ll have an experiment.
