Issue rendering - odd behavior

Adam L. wrote on 7/25/2015, 8:38 PM
I'm having a problem with rendering in Vegas Pro 12. Source is greenscreen, using New Blue v6 Chroma Key Pro. Source has a tiny bit of cropping applied using Vegas crop tool. There's an animated loop in the background that repeats for the duration of the video. Video is a little over 20 minutes in length.

The problem I am experiencing is random flickering during render, the chroma key dropping for many frames showing the raw footage, and even the entire frames being flipped vertically. This happens regardless if the video card is being used or software render only. I've been using New Blue for a while, and this happens sometime, and I'm wondering if anyone else has had these types of problems. My hardware stats are up to date in my profile.

Do you think this is a problem with New Blue, or Vegas? I'm wondering if others have seen this who aren't using New Blue.

Here's a video with the problem:

Are you sure you have disabled the GPU in rendering (not in playback/preview) cause that looks like a hardware render problem.

There are two places for the GPU to be turned off/on. One is in preferences and one is associated with the selected codes for rendering.

Yes, I just double checked to make sure - it's under Video and the option is "GPU acceleration of video processing" and the value is "off".

Wrong one.

When you select your render options, there is a under CUSTOMIZE, a drop down to select RENDER MODE.

I recently ran into a render problem with new blue colorfast. I always leave Vegas GPU off but it turns out that the Newblue effect also has it's own GPU on/off setting. Once I turn that off it rendered ok. It's accessible in the about section of the new blue effect once applied.

Donald:
Are we talking about the same version of Vegas? There isn't any "customize" drop down for rendering. There's a "customize template" button, but there's no "render mode" anywhere in there.

Marc:
Thank you Marc, I switched it off and it seems to be rendering without error. However, this is a completely unacceptable configuration. It's taken over 4 hours so far on a 20 minute clip, and it says it still has over 3 hours to go. The clip only has chroma key and a small bit of cropping, so it's not like it's trying to render Star Wars or anything crazy. This machine isn't a slow one, either. I think it's because I had GPU acceleration off for Vegas on top of it being off for NewBlue. I turned Vegas back on and I'll see what happens. Expected render time is around an hour now.

Yes, CUSTOMIZE TEMPLATE. After you select that, there is a drop down for RENDER MODE CPU or GPU

There are only two codecs where you can select CPU/GPU rendering; Sony AVC and MainConcept AVC.

Yes it definitely takes much longer to render. I've never had any luck with GPU rendering so I just bite the bullet and live with it. Adobe CS6 on the other hand has zero problems with GPU rendering. Working on a project right now in Premiere and After Effects and the quality/reliability/render speed is refreshing. FYI: I'm using a Nvidea 570 card.

Marc: very depressing. I really like Vegas' layout, and it seems so much more intuitive than Premiere. But between the issues with crashing (I have another thread on this), and having to disable GPU on this PC, I'm beginning to think maybe Premiere might be where I'm going to go. I guess the upside is Premiere has an incredible amount of 3rd party offerings that Vegas simply cannot even come close. Just sucks that I'm way more familiar with this product.

Anyway, I have a new PC that I usually only use to compose music on, but I installed Vegas and my plugins on it. It worked just fine with GPU enabled on everything. Rendered it all in about an hour and without any problems. This machine is *still* rendering the 20 minute clip, and says it has almost 4 and a half hours left (and two hours ago it said it had around 4 hours left, so who the hell knows how long it's really going to take). Cancelling the render on this one, obviously.

I use both. I actually prefer Premiere for certain types of projects now. I used to hate it but I forced myself to become familiar with it and it actually works well for certain projects. After Effects integration and text/graphic quality is also amazing.

I do prefer Vegas for many types of projects and it's timeline fluidity is great but it really chokes for me on large projects. The same computer runs Premiere CS6 without a hitch. Working on a corporate training video now that I started in Vegas and had to switch to Premiere because of crashing.

Not sure what I'll do in the future. I really dislike the Cloud model so I'm keeping my eye on Resolve 12, Vegas 14? and whatever else comes down the pike. CS6 is already outdated by not supporting XAVC.
