Black overlay appears when merging a transparent video to another video
13 juin 2012, par RakeshSThis is what I have done so far :
Command to create a transparent PNG image :
convert -size 640x480 -background transparent -fill blue \
-gravity South label:ROCK image1-0.pngCommand to create a transparent video :
ffmpeg -loop 1 -f image2 -i image1-0.png -r 20 -vframes 100 \
-vcodec png -pix_fmt bgra mov-1.mov(as per this post) - I expect this video to be a transparent video.
Command to overlay a video with another :
ffmpeg -i final-video.mov -sameq -ar 44100 \
-vf "movie=mov-1.mov [logo];[in][logo] overlay=0:0 [out]" \
-strict experimental final-video.movAbove commands works perfect and I have not faced any problem, but I don't get what I expect which is kinda watermarking effect, I want mov-1.mov to be transparent with final-video.mov.
Questions :
- Is there any way to verify if the generated video is transparent ? other than merging ?
- Not sure why the above mov-1.mov is not transparent when it is merged with final-video.mov, any info to solve this problem would be great.
Please help.
