Very slow adding of markers

[Martin Baker]

This is not a new issue. 99% of the time, adding new markers to a sequence is very slow. You can actually see the markers being added in the UI at the rate of about 1 per second. The whole app locks up during this process and frequently needs to be force quit.

Is there a known reason for this? And any workarounds to avoid it?

Interestingly today I had one example where markers were added instantly, but can't replicate it and I don't know what was different.

thanks

Nobody else is seeing this? I have screen cap evidence.

That's bizarre; I haven't seen it.

PProPanel's "Add Sequence Markers" seems pretty snappy; any further specifics you can provide?

Hi Bruce

I've identified what's causing this now. The slow import happens if the target sequence is currently selected in the Project panel AND Metadata > Clip is visible.

• 43 sequence markers take 35 secs to import if sequence is selected in project panel and Metadata > Clip section is visible.
• With no item selected in Project panel, the same import to same sequence takes 6 seconds.

When users are importing hundreds of markers on a sequence, this difference has a big impact!

Excellent find; I can repro the behavior.

We're tracking this as DVAPR-4205892.

Reopening this because unfortunately it is back. This problem was definitely fixed in a previous version, but has resurfaced in a different guise.

I'm adding 200 markers onto a multicam sequence. The target sequence is not open anywhere:

• it is not selected in the project panel so is not being viewed in the Metadata or Markers panels.
• it is not open in the Source or Program monitors.

It takes 1m45s to add 200 markers onto this sequence. During that time the CPU usage rockets up to 100%, so the fans on the MacBook Pro start kicking in and PP locks up as "not responding" app.

Strange.

Send me the project with which you're testing, and we'll have a look.  [b b b at adobe dot com]

I did some more testing with this today and while it's odd that I saw slowness with no items selected in the Project panel, it is 100% replicable by having the target item (that markers are being added to), selected in the Project panel AND having the Metadata panel visible.

Adding 100 markers:

• Takes 11 seconds with another clip selected in the Project panel.
• Takes 3 minutes 50 seconds with the target sequence selected in the project panel.

As you can see on the slow version, the adding of markers starts fast and gets slower and slower. A recent customer's file had 900 markers which brings the system to its knees...

Also there seems to be lots of main thread action going on here. While markers are being imported, the spinnning beach ball shows and the app is "not responding".

Awesome! I've been having people mention this to me about my extension and I couldn't help finding out what is causing it. Thank you so much for testing.
