I work in a projects with a lot of captions. I have timelines with 30 to 70 minutes with captions.
Zoomed out to the whole timeline and visible captions my timeline starts to lag BIG time. The timeline zoomed in works just fine. Hiding the captions is also ok.

I've noticed this as well and filed a bug while the feature was still in the public beta. Performance has definitely improved since then, but it definitely declines on super long timelines or even when you have multiple sequences open. I've also found that the solution is either zooming in or toggling the Caption track's visibilty off.

Thanks for both of you commenting on zooming in to a smaller section of the timeline or disabling the caption track to demonstrate the issue. I don't recall that in other posts about performance lagging with the new caption workflow.
I do not see a bug report in uservoice on this, but they are hard to find. If either of you file a bug report, please post a link here so we can upvote.
Hi BonteKoe Media,
We're sorry about the poor experience. We can get this checked. Please let us know if this is a UI lag that you are observing or is it a lag with the playback of the timeline? Also, is this happening with any specific caption type, or is it with all of them?
This playback performance with the captions visible and the timeline zoomed out is still present.
The workaround in Mac is to create a new profile and work fom there. However, ones you have an update, you have to create a new profile on your Mac because of lag with captions visible. Again and again.
I have been told by a Mac expert that its a matter of rights. Its an Adobe problem in my view. A Creative Cloud problem.
I've been keeping a close eye on this issue due to the amount time lost by the lag spikes
The lag spikes can be/are trigged by:
- clicks in the caption track timeline
- any text change or caption merging in text panel captions tab and or program window
- rolling the caption clips to adjust timing in the caption track in the timeline
The lag is present when both, the timeline has either multiple clips/edits that have been transcribed, or when an entire sequence is nested in the timeline and then transcribed.
with the time lost from editing, i've been able to google and read up on any work arounds to help with any kind performance improvement durring the caption editing phase of my workflow.
Workarounds I've found and done to help improve performance marginally are:
- zoom into timeline, showing only 2-5 caption clips at a time
- disable video track with video on it
- disabled "Show duplicate frame markers", as advised by is mac based user, who claims fixed his lag issues.
- disable caption track in timeline and making text changes through text panel caption tab
- lower playback quality to 1/4
- resetting my preferneces to default
but still, I am working through 20 minute edit, with about +700 caption clips with the lag spikes, because this is still faster then manually listing and typing out each caption as a text layer. Roughly takes almost 2-3hrs just to get through the caption editing with the lag.
