Comment (by edumj):
Ok, no error with full file!
But the 1000 fps thing...
I used this full command:
{{{
"ffmpeg" -i "%~1" -lavfi
[0:s:0][0:v]scale2ref[subs][video];[video][subs]overlay -map 0:a:1 -f avi
-c:v libxvid -b:v 1500k -vtag XVID -c:a libmp3lame -b:a 128k
"overlay+scale2ref -lavfi.avi"
}}}
And the resulting video is 1000 fps and very "pixelated" (low bitrate),
but if I add "-r 25" as output, it's Ok. Do I have to always especify
framerate for lavfi to work?
