Generally speaking, it is more common to add srt subtitles to a video. Here is how to add subtitles to youtube videos. The first thing to do is to download video subtitles, here you can use a chrome extension: YouTube™ Dual Subtitles, you can download your Required subtitle file. If you have a more convenient way to download, please let us know. Next, re-burn the subtitles and video. MKVToolNix can only do that kind of separated subtitles, but some video sites such as Bilibili need to upload and burn it. For better compatibility, it is recommended to always re-burn the video and file. Do it with ffmpeg:

ffmpeg -i input.mp4 -vf subtitles=input.srt output.mp4

If you need to make bilingual subtitles (display at the same time, instead of subtitle tracks), after youtube selects automatic translation, click Chinese, if the video supports, the file download of bilingual subtitles will appear. If the video does not support bilingual subtitle download, you can use the ffmpeg command twice, the first to add the main subtitle and the second to add the subtitle. The first operation uses MarginV for vertical differentiation. For more parameters, you can refer to the ffmpeg documentation yourself.

ffmpeg -i hack.mp4 -strict -2 -vf subtitles=hack_en.srt:force_style='Fontsize=20\,Fontname=FZYBKSJW--GB1-0\,MarginV=30\,Bold=-1\,BorderStyle=1 ' -qscale:v 3 hack_with_en.mp4
ffmpeg -i hack_with_en.mp4 -strict -2 -vf subtitles=hack_en.srt:force_style
='Fontsize=15\,Fontname=FZYBKSJW--GB1-0\,Bold=-1\,BorderStyle=1' -qscale:v 3 hack_with_double_subtitles.mp4
