I have always been told that a capture should be done on a second hard drive. That helps avoid the situation where program/OS access to the system drive competes with the capture process for disk resources. A capture that works well at first, but deteriorates sounds to me like that sort of contention. I suspect your laptop has only one drive.

As I said, I always preprocess photos in Photoshop so that Vegas does not get involved in resizing, etc. However, if this pixelation only occurs in QT, it sounds like an Apple problem rather than a Vegas problem.

If you are using text, the text is probably pixelating when you reduce the resolution. Before changing the resolution, rasterize and/or flatten the image. Then use bicubic sharper to reduce the size.
Most video editors are more interested in the correct ratio between the horizontal and vertical dimensions than in an actual pixel count. That means you may not have to reduce the resolution if you simply adjust the horizontal and vertical dimensions to produce the desired ratio. with that said, I usually prefer to resize in Photoshop rather than depending on the video editor.

Pixelation can probably be expected on a 38 kbyte file. I just saved a 1920×1080 photo as a tif (3.8 mbytes) and as a jpeg (1.6 mbytes) with quality level 12. Thus, 38 kbytes is quite small, and can be expected to pixelate. On the other hand, 3-4 mbytes is a bit large. Rather than file size, it would be helpful to know the pixel dimensions and bit depth of the files. I assume that they are rgb. I always try to remember that Vegas is not a still photo editor. I try to give it still images that do not require much processing in Vegas.
Also, I don’t think anyone would see a few frames in a video if it is being viewed at normal speed.

Why are you not using Vegas for the capture? Nero is probably causing your problem.

You are probably looking for a Copystand. Check B&H Photo and Video for examples.

Don’t make it any larger than necessary to support the zoom. Large image files, in my experience, will quickly slow Vegas down. Also, when judging if the resolution is sufficient, be sure that the preview screen is set to “Best”. I usually use Best-Full.

Try dragging from the layers “box” (mine is on the lower right corner of the workspace). If all else fails, you can always copy and paste.

I am not defending QT. I am simply asking why Vegas continues to depend on it rather than relying on its own code. Although I may be mistaken, I am under the impression that Vegas will install QT if you do not already have it. My impression is also that Vegas cannot process certain file types, like tifs, without QT.

I would start with Color Curves. Curves allow selective changes to different tones. Shadows versus highlights for example.
