Is there any way to burn text into a video without re-encoding? I ask this because the re-encoding process goes at around 0.1x speed on my device when writing to WEBM. Alternatively, if there is a faster way to render high quality video quickly while still re-encoding that would be great. I vaguely remember someone writing to a temporary file to solve this problem.

Also small error in program, code attatched

    sound_input = ffmpeg.input(str(audio_path))
