My camcorder is a new Panasonic VX981. I was using Adobe Elements and had no issues using that. I have since started using a different computer (which is the one I provided specs on) and started using Vegas 15 on it and have experienced this issue.

As a test, I created a new project and added the video from my VX981. When I inserted the video, Vegas 15 asked me if I want to use the settings from this video for the project and I clicked yes. The preview was jerky still - I then created the project.- no change, still jerky with pixelations.

Hi @Marias-Dad is the source media from your Panasonic 4K? If you provide a screenshot or copy and paste the source media spec's here that is reported from Mediainfo as @Steve Grisetti suggested, it may help members help you.

Which Vegas product are you using and the build may also be helpful. There is Vegas Pro 15 and there is Vegas Movie Studio 15.

Other information you could post a screenshot of is your Project Properties and the render format Template you used for rendering.

The source media is not 4k. I am using Vegas Movie Studio 15. I have attempted to attach a PDF that has the responses you requested but this rich text editor won't accept it, so I uploaded the PDF to Google drive:

There's a number of things you can look into: for the preview, see if you can activate hardware support if you have a supported card; create video proxies; use draft or preview mode in preview unless you are checking focus and coloring. For the bounced video, MS can output in dozens of different qualities and formats and most likely you have accidentally chosen (or set up in your project) a low bitrate output, which will make a very small file with terrible quality. To remedy this, on "Make Movie", chose Advanced Option and select a better output configuration.

I never used Elements but I suspect it may be more oriented to casual users, with Vegas you have a little learning curve, but keep in mind that if something doesn't work it's almost invariably because something you haven't learned/discovered yet, so simply ask.

I resolved the poor output video issue - it was my video card. When I made my videos using Elements I was on a newer laptop but I wanted to use my desktop going forward. So when I received Vegas MS 15 Platinum I installed it on my older desktop, which was using just the VGA video adapter on the motherboard. I installed a new video card (using HDMI) and the difference is astonishing.

The videos I create are very good, but the preview in MS 15 Platinum is not smooth still. I tried changing the preview properties using Draft/Preview/Good/Best, Full/Half/Quarter/Auto but no matter what I do the video will render, pause, render, pause, etc even though the audio is smooth. How do I fix this?

You are aware of the fact that you may install, register and operate VMS on TWO computers? So also on your laptop!

To tell more about your preview problem, we need more details like Musicvid already pointed out.
