9 juillet 2019, par Mohamed Adel El-BadryI am trying to cut part of a video from a remote location. Is it better to download the files locally first before start cutting it or this is a bad method ?

How can I burn in .ass file and a watermark to a video file using ffmpeg simultaneously ?
9 mai 2023, par CandourI want to add subtitles and a watermark to a video using ffmpeg. For now I'm using Handbrake to burn in the subtitles and later I execute an ffmpeg command to add a watermark from png file.


The watermark command :


ffmpeg -i F:\ffmpeg\bin\video.mp4 -i F:\ffmpeg\bin\logo.png -filter_complex "[1]format=rgba,colorchannelmixer=aa=0.4[logo];[logo][0]scale2ref=oh*mdar:ih*0.07[logo][video];[video][logo]overlay=(main_w-overlay_w)-10:10" output.mp4



I was wondering how a command would look like if I wanted to skip the Handbrake part and burn the subtitles in directly in the same command as the watermark.


Well, I understand the basics of ffmpeg commands and I tried to combine the commands but i got lost. I think the third input would be needed that somehow also goes in the overlay filter. I really hope someone can help
