For anyone who does editing of anime and other videos that use

Well shit....editing the subtitle files themselves would be hell, I'd have to change the time for each line right?

Is there any way to offset the subtitles in two different locations? MKVToolnix comes with the option to offset subtitles, but only once (overall).

Well, first thing, use aegisub.

Second, work with frames, not milliseconds, it's just easier.

Load video and subs in aegisub

Then shift select the first chunk and shift the time (subtitle > shift times) however you want.

Do the same thing with second chunk.

Pay attention to the audio waveform, it helps you a lot

Aegisub lets you shift arbitrary blocks of lines by arbitrary numbers of frames and/or milliseconds. It also lets you then automatically resnap those shifted subs to nearby keyframes. So it's mostly automatable, especially when you ignore the audio altogether (since you probably don't know the original timer's leadin/leadout preferences and how much leadin/leadout is an autism tarpit) and retime by how many frames signs need to be shifted.

That said, I'd suggest you don't do it, because if you need to be told this you probably don't know how to tell when you've gotten it right. Find someone working on it who HAS timed before, it should be easy timers are absolute dime-a-dozen bottomfeeders, and offer to work with them.

I'm an ex fansubber. unit_zero_fun if it matters.
Do you have the BDMVs?
I've been thinking of doing a small BD project to get back into it.
