Sone385engsub Convert020002 - Min Hot
Open the video in VLC or MPC-HC. Jump to 02:00:02 (type Ctrl+T, enter 02:00:02). Confirm that this is indeed the "hot" scene you want.
If "hot" implies fast motion or high complexity, increase bitrate: sone385engsub convert020002 min hot
ffmpeg -i hot_clip.mkv -c:v libx264 -crf 18 -preset slow -c:a aac -b:a 320k sone385_hot_highqual.mp4
Pro tip: To fix exactly at 02:00:02, split the video at that point, shift subs for the second half only. Open the video in VLC or MPC-HC
