For Windows:

Download:
youtube-dl
streamlink
ffmpeg

Put youtube-dl.exe and ffmpeg.exe in home folder.

Open PowerShell.

If YouTube:

./youtube-dl -o 'temp.mp4' -f 298/134 VIDEOSLUG

If Twitch:

streamlink VIDEOURL 720p60 --hls-prefer-ffmpeg -o temp.mp4

(change 720p60 to 360p if no 720p60 source)
((change 360p to best if no 360p source))

Apply frame count:

./ffmpeg -i temp.mp4 -vf "drawtext=text=%{n}: start_number=1: x=10: y=10: fontcolor=black: fontsize=24: box=1: boxcolor=white: boxborderw=5" -preset ultrafast -c:a copy tempframes.mp4
