How to deal with video sync at high buffer rate?

Hello community, I started writing for a video and all was going well until more instruments kicked in, so I had to raise the buffer from 64 to 1026, now all the music is completely out of sync with the video.

Any thoughts?

That’s interesting: I didn’t think that changing the buffer size would affect video sync, though changing the sample rate certainly can. Having changed the buffer size, try detaching the video, renaming the video’s filename so that it’s different than it was before, then re-attach the video; this will prompt Dorico to recreate the audio file for the video soundtrack. Does that help at all?

Yep, that did it thank you!
