I want to overlay semi-transparent video over the image with blend filter. However when I use blend=all_mode='addition' video becomes pink. Here is the command, how can I improve it?
ffmpeg -i overlay_video.mp4 -i background_image.png -filter_complex "[0:v]setdar=dar=16/9,scale=1280:720,format=rgba[vid];[1:v]setdar=dar=16/9,scale=1280:720[img];[img][vid]blend=all_mode='addition':all_opacity=1,format=yuv420p10le" -c:v libx264 -c:a aac -strict -2 -ac 2 -b:a 256k -pix_fmt yuv420p -y output.mp4
