Why would someone choose their video editor based on GPU support? Why would someone choose their still photo editor based on GPU support? Have many people forgotten that there is such a thing as a CPU? I have never used GPU support because I do not need it. My CPU is more than fast enough to support my editing needs when it comes to video. Vegas offers me a far better ability to edit my videos than Adobe does. Adobe is excellent for editing still photos. Vegas is excellent for editing video and sound. That is why I choose Adobe for still photos, and Vegas for video and audio. However, let’s take that a step farther. Izotope is far better for editing audio when you need to repair defects in the audio. So….you use the tool that works best to accomplish the end purpose. GPU is a consideration, but a minor one.
Go with Adobe, and pay ransomeware forever. I have CS6, and do not plan to upgrade beyond that point. Perhaps, Adobe will someday understand that its customers do not wish to be held captive to their desire for a permanent flow of revenue. Or, perhaps someday photographers will see a better alternative to Adobe. Video and audio people already have a better alternative.

Where, or what, is the Data Import Utility? I know about File -> Import and Device Explorer. Do you mean one of those?

If you simply copied the files from your SD card to the computer, you will have this kind of problem. It essentially means that a split file has not been properly imported. My HFG30’s manual describes the procedure for importing the files from the camera using the Canon software, and, although it has been awhile, I think I have used the procedure successfully.
I’m pretty sure there is a comparable capability in Vegas, but you have to go to “device explorer” to use it. Device explorer is located in the “View” tab.

OK, Tamron is the problem, and, yes, I think the jaggies you are seeing are part of the chromatic aberration. When a lens is not perfectly focused, it will produce this sort of distortion. As the article noted, reducing the contrast is one way to reduce the problem. A different background color should also help although some colors will work better than others.
One other thing to think about is the importance of the problem. I have noticed that many glitches that you can see in an image will not be noticed in a video. People will simply not see many of the things that you do because the image is changing quickly and we tend to sit much farther away from the screen.

In my opinion, that is chromatic aberration (also known as color fringing). It is not unusual, and is essentially a defect or limitation of the lens. Changing apertures will not help. Getting closer so that everything is enlarged will help. Yes, I have seen it in my photos where there is a strong backlight which creates a high contrast situation, and fairly well defined edges. There are many discussions of this on the internet. Here is one on Wikipedia;

I think you said you used a couple of lenses. Specifically, which ones? High quality lenses, “L” class or better for Canon, should reduce this problem substantially. Photoshop CS6 has the ability to reduce chromatic aberration within its raw format processor. I am not aware of anything like that for video.
-
Another possible explanation is chromatic aberration which is caused by the camera lens. However, without an image to see what you are talking about, we can only speculate. If a problem originates within the camera, it becomes much harder to overcome.

What software are you using to separate the smoke from the background? My suspicion is that your separation is not as good as you think it is. The imperfections are hidden by the black background. You are probably seeing the true selection in Vegas. It probably does not look as good because the original black background is no longer present.

Try the compressor that Vegas adds to all audio tracks.

I finally saw it. It looks like you need to log in to the profile, even though you are already logged in, before you see that item, or to update your profile.

Have you tried reverting to Microsoft Sound Mapper as your audio device? That’s what my copy of Vegas Pro drops back to when my outboard device is not powered up. Perhaps the problem is being caused by your RME Fireface 800 sound-card.
