Composition preview speed

[neilkinnish]

Really interesting library. I've been playing in the same area with Web codecs for a while.

I have some questions (apologies if this is not the best place, but I couldn't see the answers in the docs).

Removing many sections of a composition via clips / tracks, can take a little time to update on the composition preview (I don't mean export) on for example a 10 minute video, is this expected?

For reference I've been playing with both subclips and split.

Have you built in functionality to fade the audio volume from 0 on a cut.

Happy to look at contributing, just trying to orientate my self first.

Thanks! Sorry for the late response.

Removing clips and tracks should be a fast operation, do you have an example to demonstrate this issue?

Audio fade is not implemented yet, but we will definitely support it in the near term.
