rtuite Posted May 22, 2017 Share Posted May 22, 2017 I am getting the "building preview" when trying to preview to make sure my text animations and transitions look right. My machine is a year-old core i5 with 16 GB of RAM and a Samsung SSD, and none of these resources are being stressed at all. Is there some setting I'm unaware of to allow VP to use more of my system's available resources, or is it just this laggy? Link to comment Share on other sites More sharing options...
borate Posted May 22, 2017 Share Posted May 22, 2017 Three things to try... In OPTIONS, under the EDITING tab, toggle the "use hardware-accelerated video effects" checkbox to the opposite choice. Right-click in the preview window, click CHANGE PREVIEW SETTINGS and choose a lower resolution. Install the latest VP version. Link to comment Share on other sites More sharing options...
Nationalsolo Posted May 22, 2017 Share Posted May 22, 2017 Hi Check the Preview Format pane Preset box under Tools/Options/Display and reset it to 512 x 288 (16:9) You may have yours set too high for your PC to have the time to generate all the thumbnail and preview images etc. If this is the case and you are trying to preview your edit it can produce the "Building Preview" message Nat Link to comment Share on other sites More sharing options...
Aresby Posted May 23, 2017 Share Posted May 23, 2017 But the question remains, why does it say (on my videos, at least) that it's "Building Preview" each time I try and preview past some transitions? Not all transitions, but on the ones where it does state this, it stubbornly refuses to ever let me preview that bit of the video in real time (I just hope, and review the final exported video). I've found that once I've been editing for about 20 minutes (in which time I've probably got several dozen cross-fade transitions where I remove "Erm" and "Ums" and other such mutterings) this is when it all goes a bit "Building Preview" crazy. I've (sort of) learned to live with this constraint but it's still quite annoying. I've downgraded the preview resolution past the point where I can read any on printed matter, such as eBay listings (so that's not acceptable) but it made no difference anyway. I realise that my graphics card is bottom of the list but there's no upgrade path for me there in my Ultra Small Form Factor PC. (sad face).

borate Posted May 23, 2017 Share Posted May 23, 2017 Does clearing the CACHE help or hinder? Link to comment Share on other sites More sharing options...
rtuite Posted May 23, 2017 Author Share Posted May 23, 2017 My preview resolution is already at 512 x 288 and I tried clearing the cache as well with no effect. Link to comment Share on other sites More sharing options...

To be honest, although I occasionally clear out unused cache files (by clicking that button) I find that if I clear the cache it takes forever just to build all the preview timeline snapshots again so I tend to avoid doing this. I'm 90% certain I tried this in the past (probably as a result of someone here suggesting it!) and it made no difference. Link to comment Share on other sites More sharing options...
borate Posted May 23, 2017 Share Posted May 23, 2017 And what about the "use hardware-accelerated video effects" ? Did switching that ON or OFF make any difference? Have you cleared Windows TEMP files lately? Here's a handy free utility. Link to comment Share on other sites More sharing options...

It's probably more likely on a zoom (I zoom into a portion of the screen in about 1 second, stay zoomed in for maybe 10 seconds, then back out again). However, even on pretty standard crossfades it can happen. I don't use that many effects so if it's going to happen it will happen on a very limited set anyway.

I've not cleared out the TEMP file but I'm confused why that is relevant? I use a special folder for all VP files for temporary cache files.
