Defocus stepping
Posted by Steve Roberts on November 19, 2012 at 11:29 pmHi all,
So far Vegas 12 has been great. Only crashing that I’ve had I’m blaming on an old codec from previous work that I’ve recently been working on again.
QUESTION: I’m doing a defocus from 0.5 to 0 over 4 seconds and it’s noticably stepping. By this I mean I seeing the defocus effect only change about 5 times over this time period. Not smooth.
Is this something that Vegas has always done or is this a new “feature”.
Cheers,
Steve R.

November 20, 2012 at 1:40 amWhat is your previous non-stepping comparison to? Vegas 11? 10? Earlier? There are several possibilities here. If this is your first go round with an OFX version of Vegas you can be unaware of keyframes being inserted (i.e. the hard stops you are experiencing) because the new interface is slightly different and you were not visually aware that your messing with parameters created new keyframes. Sometimes this happens so close together that visually you only see one keyframe where there are two. The second possibility is that with each update and iteration a few more plugins are made compatible with GPU acceleration. Turning it off may revert defocus back to a CPU calculated gradual curve.

|What is your previous non-stepping comparison to? Vegas 11? 10? Earlier?
No comparison. Just started to notice it.
I’ve doubled checked the keyframes and all is good. There’s just 2 keyframes – the start and the end.
In Vegas 10, my last version, I had CUDA available but I don’t in Vegas 12 which is fine, so CUDA is not the issue. Which I understand you meaning with regards to the GPU ?
I could reload Vegas 10 and test it in that. Maybe one day.
Gaussian Blur is doing the job for me now. But it’s not as pretty !
Steve.

November 20, 2012 at 6:13 amYou answered my question about comparison… it was working fine for you in Vegas 10. That was the first version with OFX so back then it was probably the same plugin as it is now. The fact you had CUDA working for you in 10 and not now might be the problem (which would be the opposite of what I thought.) It might be that the CPU calculations of defocus are not as good as the CUDA version for whatever reason.

November 20, 2012 at 6:18 amSorry Matt. My simple answer was misleading regarding the Vegas versions. No I have not noticed this problem in any other versions of Vegas meaning I didn’t notice if the effect was working correctly or incorrectly. For all I know is that it’s the same in my previous version.

November 20, 2012 at 6:48 amI tried a 4 second clip with defocus 0.5 to 0 in both 8 bit and 32 bit pixel format project properties and both seemed smooth although 8 bit was a little fuzzier. I am assuming radius was the only parameter you changed? Do you have a way to post your clip to the forum?

September 4, 2013 at 7:59 pmHi,
I seem to be experiencing the exact same problem. Animating the Radius of the Defocus effect (other parameters left to default) leads to ugly stepping, using 8 bit as well as 32 bit pixel format. This doesn’t happen in Vegas Pro 9. Here is a comparison, rendered losslessly using CPU only.
Any idea what might be causing this?
