also 8 bit RGB and YUV formats with alpha to allowed input formats.
If the input has alpha then only alpha levels are altered.
Typical simple cmmand might be:
./ffmpeg -i background.mov -vf
"movie=strap.mov,fade=in:0:25,fade=out:99:25 [strap];[in][strap]
overlay=0:0:rgb=1 [out]" -vframes 125 -vcodec [...] out.mov
