Sony Vegas Radial Blur (Proportional) BUG ISSUE - PLEASE HELP!

james-b wrote on 10/15/2016, 6:24 AM

Hi, I'm writing on behalf of a friend of mine who has no internet at the moment.

He's been making Videos on a game for a while and has been using Sony Vegas to edit. He recently upgraded (after years of using version 9) to SV14. And now whenever he tries to use the Radial Blur (Proportional) effect, it doesn't come out like it should. It appears both pixelated, and as if the "Radial" and the "Blur" are seperate from eachother - the effect doesn't blend into the radial centre.

Here is how it should look: https://gyazo.com/e027597dc448c1070269d67d5ef65ed4

Here is how it currently looks: https://gyazo.com/fbe9d8cc1ac7eada687405e99242a20f

Notice that in the first pic (even though there's colour corrections in it), the radial blur effects blends well and you can't specifically see the oval lines anywhere. Whereas in the 2nd pic, there simply appears to be an oval (which pixelates the entire clip) with blurs that are detatched and un-blended around it.

He says this bug is only evident in the "Proportional" version of the Radial Blur - all other effects work as they should.

I've had the same issue to this in the past, but can't remember how I fixed it (I remember changing some sort of setting or something in SV, but that was years ago and can't remember what I did).

Cheers for reading :) hopefully you guys can help him out!

same links 😉

BTW you can upload your pictures here direkt

Oops lol. Attached it below. But yeah, quite clearly something is wrong.. It appears the pixelation occurs closer to the edge of the Oval (the text box for example is pixelated, which isn't usually so).

I've deleted it
This was wrong sorry

No worries - I've deleted mine as well. Also have edited my original post with an example of how it should be.

Can you upload a picture from this original scene without FX?

Will need to ask my friend to provide a specific one - he's sleeping now so will get back to you in the morning.

But here's a similar one that's unedited (they'll look exactly the same):

The result of the effect depends on the picture content

Not in this case. In the morning I'll send him that original photo, so you can see the difference between YOUR effect on that photo vs his, and you'll notice a substancial difference despite the same image.

And that difference is simply exactly what I stated above.

Ok, let's see

here is a test with another pic

Here it is. You can clearly see that in yours, there appears to be no "Oval" cut-off, and the blurs blend in with the radius nicely giving a full effect. Whereas in his photo, there appears to be an unusual cut-off in the shape of an Oval where the radial blurs disconnect.

He has also sent me a GIF further illustrating this issue through animation of this effect (where normally animating this effect gives the illusion of stronger/weaker radial blurs, but for him it simply changes the size of the Oval - which makes it appear quite pixelated and glitched, which is the case - and animating it makes it more obvious).

does GPU on or off make a difference?

Not sure - how does one do this?

Options > Preferences > Video. Change it and restart Vegas.

Here the result (GPU ON) left is yours in trimmer

Settings: Default/Proportional/Strengh:650

AWESOME. That fixed it :). Thanks so much for your help!

Also, will turning off that GPU setting slow down the rendering or processing times at all? If so, by how much (estimate), and is there any way to turn that setting on without getting that glitch? Or will we have to wait for an update to fix it?

it depends of the video card you are using
here is a good explaining:

Some things behave slightly differently if you have GPU acceleration of video processing on or off. The gaussian blur FX is one of them. This was the case in VP13 and VP14 renders with exactly the same difference. You can verify this like this:

Put a "small tiles" generated media checkerboard on the timeline
Add a gaussian blur FX with the "soften" preset
Switch off GPU acceleration and restart if necessary
Render an uncompressed or lossless AVI file
Repeat with GPU acceleration on
Put the rendered files back on the timeline and compare the tracks by muting them while viewing the video scopes. You can see the scopes change slightly between versions that were rendered with and without GPU on.
