Hi @kkxlkkxllb . I’m glad It compiled nicely. I have one more tip for you. You will need to upload the font file you want to use on your subtitles and then specify it on your command. I’m away from the computer, but as soon as possible, I’ll share some code to show how I’m doing.

Here is the example code:

ffmpeg.FS('writeFile', 'output.mp4', YourVideoFile);
ffmpeg.FS('writeFile', 'xxx.srt', YourSubtitleFile);
ffmpeg.FS('writeFile', `tmp/arial`, Arial.ttf); 

ffmepg.run('-i', 'output.mp4', '-vf', 'subtitles=xxx.srt:fontsdir=/tmp:force_style="Fontname=Arial"', this.output);
