Still image pixellation

[Devon Thomas treadwell]

I uploaded the video so you can take a look. The pixelated still images begin at 1:28.

Hmmm, maybe this is a clue… the pixelation seems to be triggered by fades and crossfades.

[Devon Thomas Treadwell] “The still image clip looks OK at first, but the longer it goes, the worse the pixelation.”

There’s quite a bit of noisy pixellation in all the images and motion is worse. Maybe it’s the encode?

Try this: Render the Still and THEN do the transition. I know, this shouldn’t be necessary, but maybe the transition you’ve chosen isn’t up to mustard in dealing with the pixellation from the video?

I think your issues commence earlier than the still sequence. There’s something more fundamental than the Stills, it’s just that the Stills are showing/revealing it to you.

The issue is definitely related to fades, dissolves and pans over still images. I ended up taking out all the dissolves between the stills and left only one pan and one fade at the end. Most of the stills are much better. Here’s another render:

You can still see pixelating in the still image at 1:41, just before the next clip, which is a pan over a still. And it’s bad also at 1:56, where the still fades to black.

BTW, I’m running Windows 8. Has anyone reported any issue like this with this OS?

Hmm.. Well it is related but it still doesn’t tell us “what” is making it happen?

One shouldn’t have to remove a creative decision ‘cos of an issue, and a task which is/should be meat ‘n drink to Vegas Pro12.

I completely agree! So what the heck is causing it and how do I fix it? 🙁

[Graham Bernard]

OK . . . .

Q1] Where did you get the Stills from?

Q2] What Template are you rendering to?

Q3] What is your Project Settings?

Q1] Where did you get the Stills from? I shot them with a D90 and converted the RAW files to .png (tried .jpgs first). Images are 1920×1080, 72 dpi

Q2] What Template are you rendering to? Slightly modified YouTube setting:

Q3] What is your Project Settings?

[Graham Bernard]

Try rendering out the Stills to the match format of the Video first. Meaning don’t rely on going straight to that YT Template. Just experiment and see. Also that’s a very high bitrate. Any reason for that? You might be making too much jump to the YT render and that could be the issue.

Have you tried using images of the original size or at least 2x greater than HD. If they were 3×2 (eg, DSLR image), then 3240 x 2160. If you want 16×9, then 3840 x 2160.
