splash.pnghaving the same size as video resolution
video.mp4in 60 fps already encoded via
-vcodec h264 -crf 23 -acodec copy
I want to prepend (not overlay) video
video.mp4 with splashscreen
splash.png for 5 seconds.
If possible, I'd like to keep video without reencoding as otherwice additional artefacts may appear. Or maybe it's possible to reencode with the same codec without quality loss?
ffmpeg command I should use to achieve that?
