Preview Quality Decreased in 424

Carl-G wrote on 7/14/2019, 11:30 AM

Since using 424, I have noticed a significant decrease in quality in the Preview, "Full Best" selection (both in main window and external monitor down to Draft quality. The first couple of seconds of a still image is fine but as the timeline zooms in on the still the quality of the Preview Full Best immediately degredates to about "Draft" quality!

It did *not* do that before this update. I updated from 307 directly to 424 via the download link. Was there something I missed? I'm running an i7 with 32GB RAM, intel onboard processor, Windows 10, build 1907.

It's tough showing clients a Full "Best" Preview that erroneously becomes a Draft Preview several seconds into any effect on a still. And as mentioned, the previous build I had on here (307) worked fine and Full "Best" Previews were great in 307.

Got some screenshots? This is an unknown issue.

Here's a comparison when the Full Preview snapshot looks like (on left) and then what it turns to (on the right) this really doesn't show the full extent of the degredation of quality, but it's the first sample I could grab.

Wow, that's pretty dramatic. Here's a quick suggestion that may be worth a try: Under Options->Preferences->Video, try turning Off this switch, as mine is.

"Make sure that you have "Adjust Size and quality for optimal playback" unchecked. If its checked it'll automatically vary the quality in playback, it won't necessarily stay at Best/full, maybe not what you want.

Right click the preview window to change.

When I unchecked "Adjust Size and quality for optimal playback" some (not all) video sections in the timeline then became wildly out of sync with audio (up to 1 second offset). When I checked the option back on the video/audio sync was perfect again.

WOW! I think this may be the ticket. I turned the option off (for version 424) and the pics are clear again but now they show jagged lines on diagonal objects in the stills.... which I think can be mitigated with another option maybe?? (Which one??) I'm running an Intel HD Graphics 4600 ... and it seemed to work fine with the GPU acceleration option ON in version 307. What has Changed??? I read somewhere that there were new problems with Intel on board graphics support in the later Vegas versions (true? Not True?).
