Vegas Pro 19 / Re-generates all the clip thumbnails

steliosfan wrote on 6/7/2022, 4:06 AM

Hi all,

I'm facing a strange problem, which i never had in previous versions.

While i'm editing, if I ctr-z (undo) then all the clips in the timeline which had previews (so that i can see which one i;m editing) goes black and vegas is restructuring their previews which is frustrating and takes a lot of time.

Is there a workaround for that?

 

Thank you !

I have not noticed what you are describing but, perhaps, you might want to show some screenshots so I can verify what I am thinking you are saying is actually what you are saying.

The problem is on the thumbnails (re-building them) on the timeline when i'm undoing something

Definitely not seen that...

Nor here either. Quite the opposite ... Ctrl-Z Undo has proven to be very quick in VP19 b636 on a 1 hour 4K no-proxy project.

It seems that it re-generates all the clip thumbnails, on both my machines.... I changed into head center tail (preferences, video tab) and loads faster now, but still remains an issue

Interesting. Is this particular to a type of media- what is on your timeline?

it's Canon EOS R6, 10bit, clog files

RogerS wrote on 6/10/2022, 3:28 AM

I just loaded some Canon R5 clog 3 HEVC footage and do see that the event where I made changes loses is thumbnails momentarily after undoing. I see it with head/center/tail as well.

Do others see this too? I wonder if it's an HEVC issue. I am using legacy HEVC in file io and Intel QSV for decoding.

Thank you for checking. This is exactly my problem and as far as i can understand its a problem for everyone as it keeps on happening to my both workstations as well as yours.

10bit(422) HEVC is a true nut for VEGAS to crack.

My observation is, Canon-AVC/HEVC are not very friendly with VEGAS.

Sony-AVC/XAVC are, same those of Panasonic.

However, in Vegas 18 it worked perfectly

Moreover, this happens to the proxies as well...

If the preferences are set to "show all thumbnails" (it appears they are from your screenshot) and you have split an event and then you "undo" that split, it *will* need to redraw the thumbnails for that event. I suppose, depending on the format of the video, this could take longer on some files than others. How much difference does it make if you change it to "Head center tail" or just "Head tail"? (I like "show all" too so that's what mine is set to as well).

RogerS wrote on 6/10/2022, 7:16 AM

I just did things like adding a fadeout at the end and reducing the length slightly. If it calculated all the thumbnails once for the frames why is it needed again? Head center tail was a quicker redraw period than all frames (and this is how I set Vegas generally to improve performance).

This is not a B636 bug. It's a common behavior.

Just open the V16-sample-project with many generated clips and see how the whole track refreshes itself - and that's why so many complains to Ctr+Z in the past.

Out of curiosity is your playback smooth? Mine is only smooth on 24fps not 60fps footage using Intel QSV on a 12900K
