Does rendering twice in the same format cause loss of quality?

[Terje A. bergesen]

If you render to MPEG-2 and then edit again adding effects, you will see a loss in quality, at the wipes etc, quite possibly a very noticeable loss in quality.

Is there any reason not to add the swipes before rendering to MPEG-2, this seems like a roundabout way of doing things where both work flow and end result would suffer.

yes

To expand on Fuddam’s response, the degradation is format-dependent. If you are working with say…DV AVI files, then rendering cuts-only won’t affect the format. If you’re rendering from MPEG, it’s going to be degraded. MPEG to MPEG will lose a lot of information. Try it and see if the amount of loss is acceptable to you.

Thanks for the input… Is there a better way to accomplish my task…

I have several interviews that are on my timeline but are out-of-order from where I need them to be for my finished project. This is why I planned on rendering each individually and then importing them in the correct order onto a new timeline.

These clips are in HDV 60i and will be burned to DVD (SD) for my finished project.

Is there a better way to do this where I won’t lose quality upon my second render?

Thanks in advance for your replies

More information is very helpful.
Since it’s HDV, you won’t need to worry about it.
but I don’t understand the “order” thing. Why not just take the clips and arrange them prior to rendering? This is exactly what an NLE is for.

um……….you happy making cuts using the ‘S’ key, at the cursor position on the timeline?

then shuffling the clips around?

am just trying to ascertain whether we’re starting on the same ground

DSE,

Thanks again for your reply. I’ve heard a lot of great things about you on the web regarding your knowledge of Vegas. It’s great to see you on this forum. I’m looking forward to ordering some of your Vegas training DVDs.

Interviews: The problem is that these interview clips average about three minutes long. They have a lot of “b-roll” footage above the actual interview footage and the interviews have also been edited to the point where I would need to move a lot of footage (average of 50-60 clips per interview) around to place them in the correct order on the timeline. Is there a way where I can copy and move the entire segment (all the pieces/clips before they have been rendered) as a whole to a new area on the timeline?

Thanks again for any info you can provide.

[Adam Rose esq.]

1) press D to change the cursor, until you get the area selection cursor

2) highlight all the A/B roll material in a partic interview, by dragging the cursor over it

3) change the cursor back to the normal arrow cursor, and drag that material to a new location. If you find that a bit iffy, first press ‘G’ to group it all, then moving it (whether ripple is on or not) will be as a single object

Could also cut/paste it, if you prefer

🙂

This is more or less the method I’d use, or if there is a lot of content to be cut, you might consider opening two instances of Vegas, cutting from one and pasting into the other, building an entirely new project in the second instance, with content from the timeline of the first instance. One instance of Vegas on each screen….

Wow! Thanks for the help. That really makes things easier.

How do I create a new “instance” in Vegas where I can post these interviews into a new project? If I open a new project, it makes me completely leave the other time-line.

Again, I really appreciated the info.
