[Marc] “Also, I still haven’t been able to figure out why my DVD Architect 24p (23.976 progressive frame) mpeg 2 file is nearly identical in size to my DVD Architect 30i (29.97 interlaced fields) mpeg 2 file. Any thoughts?!”
It’s usually best to create an entirely new post/thread when you have a question that is totally unrelated to the thread you are posting to.
To answer anyway… the size of the MPEG file is mostly related to the bit-rate you specifiy and NOT the frame rate. That’s likely why the file sizes are very similar. The point of going to 24p instead of 29.97 is that you can achieve a higher quality with a reduced bit-rate.

On DV Capture Vegas only does scene detection based upon time-code changes only. If you want “optical scene detection” then you’ll need to use another product (such as Scenalyzer Live).

That sounds about right. There is a LOT of data to copy. It was still a lot quicker than your original render right? So you did come out ahead. If ever you are up against a tight deadline… I have found that minutes can count!
-
and… just to be sure here… you ARE loading a DV-AVI file back onto the timeline right? Your original post mentioned you had rendered to MPEG… and later on you mentioned that you had rendered to DV AVI. Which is it?
If you load an MPEG file back onto the timeline… that is absolutely the worst thing to do.

In order to re-render that AVI file Vegas will need to “render” the entire timeline. That is normal. However… it should do the “rendering” (actually copying) of the unchanged parts of the timeline VERY quickly.
Usually we get worried about re-rendering times when the project we are working on has a lot of FX’s and other things added to the source video that significantly adds on to the render time. If your original project is pretty much just a “straight-cuts” sort of project then it would have likely just been as simple to make changes to your original Veg and render as before. The step of adding your original AVI back to the Vega and doing all that work was making an assumption (my assumption) that your original project took a long(ish) time to render.
How long did it take for your original 100 minute file to render?

Yes… render to a new AVI file…. the old AVI file is being used to generate the new AVI file. You can’t overwrite something that you are using (at that moment) as the source of your new AVI file (sort of a catch-22 – or your would be violating the laws of physics).
Once the final render has been done… THEN you can delete the old AVI file.
By the way… remember to either delete or MUTE the audio track which you probably added when you load the rendered AVI file back into the old Veg file. Otherwise you will get duplicated audio – and the levels will be way too high.

Despite trying to offer an alternative view to the solution – I certainly am nonetheless interested in the core problem that you encountered… and ways to make it work better.
I also apologize at being rather snappy in my posts….

I understand… now… what it is that you were looking for… and that my attempt to work around the problem was offensive to your senses. Unfortunately knowing the complete context of the question (and your prior posts were NOT explicit enough to see) helps in considering the answers one gives.
You seem ncapable of taking constructive questions/discussions around the problems you posed and intent therfore on being rude to the people who attempt to look around the problem somewhat.
Despite your own issues… having wider discussions around such problems (I find anyway) leads to a much deeper level of understanding of the issues… NOT JUST between you and I.. but in a way that benefits many others who participate (viewing and posting) in this forum.
I’ll certainly add a note for future reference that you do not appreciate someone using their brain to help respond to your questions.

Thanks mate…. cheers.

I didn’t miss your point… because until now you didn’t make it. You didn’t mention VHS in your prior posts.. just DVD.
How do cable companies and the like take widescreen formatted content then? Is it not possible to produce a native widescreen format on tape. I think you CAN… as that is how you got it off the DV tape in the first place right? There are also many broadcast cameras (Digibeta etc) that capture in widescreen format to whatever tape they work with.
Still not understanding (other than VHS tape – and who uses that now anyway) why keeping it in widescreen format will not be the best way to go.
