I, too, am having this problem. I thought I had it sorted by copying the project from SVP12 back into SVP 11, but sadly, the problem persists. Mine’s a multicam shoot using Vasst Ultimate S, so it will be a pain to re-do in SVP11. Unfortunately I could not copy any of the markers across from SVP 12 to SVP 11, so I am unable to regenerate the master video track in SVP 11, so whatever is in the master video track FX persists.

The flickering is happening in my DVDA bluray and DVD PAL templates output from SVP12. It is definitely not in the source, but it is present in the rendered file before I bring it into DVDA.

I did notice my render template in SVP12 was set to render quality = best, so I am re-rendering to render quality = good. The output in my test render was slightly softer, but I did not do enough to see if the flicker had been eliminated.

The FX I am using are Colour Curves, Brightness and Contrast and Colour Corrector.

I have also noticed that the SVP 12 render templates do not allow you to select Include Audio stream and render audio as an elementary stream anymore.

I spent 1 day editing a 2 hour 12 minute multicam shoot and my computer has been running non-stop Monday night with me trying to find a workaround for this flicker issue. It is getting frustrating. I can live with SVP instability issues, but when the output is being affected by a flicker such as this, the only option seems to regress to SVP11 and start all over again.

Roger, my earlier post received zero responses. Hopefully someone will read your post. I don’t know if the problem lies in the Vasst Ultimate S Quadcam or Sony Vegas. I strongly suspect the latter as earlier versions of SVP12 were causing me grief with the Color Curve OFX plugin not being transferred properly to the master track. John Rofrano reported that issue after I raised it with Vasst support.

With this issue, it is not clear cut what the problem may be.

I can’t recall if you used Ultimate S Pro. If not, we can eliminate Ultimate S and focus on SVP12.

I regularly use a mix of 1920 AVCHD and 1440 HDV in my projects. My project properties are set to the lower of the two i.e. 1440, including my bluray renders

Copied the entire project into SVP11 and rendered it out. Flickering has gone, talk about a crazy workaround!

At least I can give the client something watchable.

I did not know about the phase cancellation issue. Good to know.

I have never actually combined L+R, I just set up my cameras to record separately to the XLR channels for later selection and isolation.

Where I have 1 camera and 1 mic, I typically leave the audio separated as is.

Your old specs look good. I actually started with that setup about 18 months ago, and upgraded the CPU to a 970. I upgraded my video card from a GT2000 to a GTX 570 and was sorely disappointed at the lack of improvement in preview performance. I spent $700 for what appeared to be next to no improvement in preview performance. I was expecting my preview to blaze along. What a let down.

I jumped off Vista 64 Ultimate as soon as Windows 7 Ultimate was released, and followed the upgrade path. I have not regretted that decision one iota. Vista 64 was a slow, unstable resource hog.

You might benefit from a faster graphics card, but with SVP11 and SVP12, a lot of stability and rendering issues have been resolving by switching off GPU acceleration in Vegas. Kinda defeats the purpose of those 1024 CUDA cores on your graphics card just sitting idle. Go figure :-).

Having said that, I have so far found SVP12 to be the most stable release of Vegas since version 10c. It has not crashed on me yet. SVP11 used to crash all the time. I still have SVP9 thru to SVP12 on my system.

With SVP12 there appears to be the odd issue, but it appears the testers and the coders are on a roll with the latest build. Finally, after 3 years!

I don’t burn from inside DVDA any more. I get too many coasters. I now use Nero or Imgburn.

It is possible to record L & R channels separately i.e. XLR and mic inputs, on cameras such as the Sony Z1P. One gets a feed from the sound desk and the other records ambient audio. You can then use left or right channel only to isolate the better or preferred audio source, or use the fader to adjust the balance or loudness between the two.

In your case, selecting combine or left channel only or right channel only should still result in mono audio being sent to both L and R on your headset.

It should not affect your DVD audio output. I prefer to use mono for dialogue as it adds to clarity and sounds more natural. To my ears anyway 😛

I don’t believe Vegas 5 would be compatible with the operating system. I am guessing it is Windows 8.

Might be time to upgrade your version of Vegas by 7 generations 🙂

CPL – reduce reflection and light, around 1.5 or 2 stop, typically when shooting landscape or water
ND – reduce light by 1 or 2 stops, prevents overblown highlights.

You can get inexpensive ND filters in sheet form to test out their effectiveness and hold them out in front of the lens

[Nigel O’neill]

Probably in your case an ND filter will achieve the best results. Depending on your camera, it may have one built in.

A CPL is most effective when you can get the light at 90 degrees to the filter. It’s great when shooting through glare off water or when you want to enhance clear blue sky. In your situation an ND1 or ND2 filter will have the most impact. You will need a bit of trial and error experimentation to get it right.
