I’m trying to trim a video and draw text on it. Although the command below “works” (source), there’s a 2-3 second delay at the beginning of the clip. Specifically, for example, if I want to trim “00:05:27”-“00:05:37”, the resulting clip seems to lag from “00:05:27”-“00:05:29”, then trim from “00:05:29″-00:05:37”.
When using -c copy, the lag/delay is gone, so I’m quite sure it’s caused by my -vf command below.
Full Command (minus paths):
ffmpeg -ss 00:05:27 -to 00:05:37 -i "..." -vf "drawtext=fontfile='OpenSans-VariableFont_wdth,wght.ttf':text='Clip 1 (00:05:27-00:05:37)':fontcolor=0xF
F0000:fontsize=40:box=1:boxcolor=black@0.5:boxborderw=15:x=w-tw-15:y=h-th-15" -c:v libx264 -c:a copy "..."
