Description

--download-sections doesn't cut the video at exact point, specified by --download-sections.
The video (https://www.youtube.com/watch?v=3LkcDrcoJ80) has the opening for the first 2 seconds, and I was trying to trim it off.

Resulting file here: https://cdn.discordapp.com/attachments/807247901981016094/991331113693884476/3-4_KGH-439_3LkcDrcoJ80.opus
You can hear the opening part, which has lower volume than the following part.

Video files cannot be cut at exact timestamps without re-encoding. --download-sections do not re-encode by default. To make it do so, use --force-keyframes-at-cuts
