clips out of focus on one timeline but not another

I have a long project, several hours.

Some of the clips are out of focus on the timeline A

However, I re-imported the same clips into another project timeline B (1 hour) and they are NOT out of focus?

The clips from timeline A were rendered to a file and then imported to timeline A.

The clips on timeline B have not ever been rendered.

So maybe the clips are not clear on timeline A as they were rendered once?

I am also thinking I should just delete all of the out of focus clips on timeline A and re-import the fresh clips and see what happens.

Or

I was once told that clips might stutter on the timeline, but once rendered come out ok. I.e. high def files are so large, it seems the computer struggles as it takes a lot of resources to process and maybe that is why "some" of the clips on timeline A are out of focus. Hmm but only some of them.

So is it possible the clips on timeline A will look ok when rendered to a disk even though they are out of focus on timeline A?

Yes I know I can just try rendering them and see how it plays once it's on the blu ray disk but it's a long project so I have hesitated but maybe I will try that too but I wanted to ask for input here too.

Preview quality settings?
But then, "someone on another forum" already said that.

osw, your username is perfect for you cuz after reading your posts, I ask myself what is he saying?

Here's what I think is the key sentence:

The clips from timeline A were rendered to a file and then imported to timeline A.

You must have "messed" them up when you rendered them. You must have changed the resolution to soften them up.

and you have the answer: re-import the fresh clips

If they're out of focus on the timeline, they'll be out of focus in the rendered disc.

You've misinterpreted the intention here. Sometimes your computer isn't powerful enough to show the Vegas preview at full frame rate in real time, especially when using larger frames, heavy codecs, and effects, titles, compositing, overlays, etc. However, once all these things have been combined and "flattened" into an output file your computer can easily play the resulting file without stuttering.

Now, it is possible to use these rendered files back on your timeline, but the benefit comes from using an easier to process codec (like MXF instead of AVC) and having your effects & titles & such already combined so that you no longer have to apply them in your project anymore. The trade-offs are that you can no longer edit these effects & titles (if you've used them) because they are now part of the new clip on the timeline, and that if you use a lower resolution or lower bitrate for your new file then the quality will drop substantially.

"and maybe that is why "some" of the clips on timeline A are out of focus. Hmm but only some of them."

The general suspicion is that you've rendered to a much lower resolution file. Make sure your new file is at the same resolution as the original and you've used a high enough bitrate to avoid degradation due to recompression.

"So is it possible the clips on timeline A will look ok when rendered to a disk even though they are out of focus on timeline A?'

Highly unlikely. In fact i'd say flat out "no". The preview window is there to show you what the final output is going to look like.
