in `create_overlays` the `text()` command takes about 40% of running time
Opened this issue · 2 comments
Using Rprof(), I identified that the function text() takes nearly 40% of the running time. Steps to do:
- confirm again
- try out using
ffmpegwith the filterdraw texthttps://ffmpeg.org/ffmpeg-filters.html#drawtext-1
Thew .ass subtitle format could be used for this. see https://fileformats.fandom.com/wiki/SubStation_Alpha and http://www.astro-electronic.de/FFmpeg_Book.pdf
ffmpeg -i background.avi -vf subtitles=overlay.ass -y final.avi
