I made a little video for Vimeo a while back that covers this for a general audience and it’s got some background on the topic:
More specifically, in Vegas:
* Interpolate means you toss away one interlaced field and duplicate the other to create your progressive frame (at the cost of half of your resolution).
* Blend means the two fields are averaged together into the progressive frame.
* None means the two fields are just glued together as-is into the progressive frame. This is probably what you get if you just upload interlaced video to Vimeo. This is definitely not necessarily the disaster it sounds like and is, for the most part, good enough.
Conventional wisdom says that you should use Interpolate on high-motion video (it’ll create sharper edges on fast moving objects) and Blend on relatively static shots. That’s not terrible advice. Honestly though, you can use whatever you want. Sure, blend will result in a softer, blurred look on high-motion, but isn’t that apart of the 24p Magical Mystical Film Look that everyone is obsessed with? So maybe you DO want to Blend high motion. Really the choice is yours. And you can make it at the very end of your project before rendering, but once you settle on a technique, it’s probably better to start with your project using your chosen method.
Some caveats:
1. Toggle the Preview Window to “Best (Full)” to actually see the output frames when fooling around with interlacing settings, however…
2. Do NOT make your deinterlacing decision based on still frames. The only way you can judge is by watching the video in full motion, so Shift+B a section of video to see the results. -
Theoretically: the speaking is probably between 80-250Hz, but, unfortunately, the waves might span everything from very high sand particles tinkling about to the subsonic rumbling crash. I do not envy you your task.
But I would like to hear the non-theoretical real-world practical answer you arrive at.

A 7.2x render does seem a bit long, but there are so many variables, it’s hard to say if it’s broken. What are you rendering out to, for example? 2-pass VBR (which means almost 2x render time)?
I’m popping in here right this minute because I’m rendering something: 00:6:15 project that is going to take 25 minutes to render (single pass to QT-ANI archive), which is about 4x render time. I’m on the same system as you, with 2GB more RAM (which won’t make a difference) and the processor OC’d to 3.0GHz (which will make some difference, but nothing radical).
So I’m not certain anything is wrong, but in any case, I’d definitely not mind waiting overnight for a best quality 2-pass VBR render on a 100 minute file. [oldmanvoice]Why, back in my day, we walked to the studio through waist deep snow and a one minute file took 10 hours to render…[/oldmanvoice]

Not too shabby at all, I love it!
I’m unclear how you pulled it off: How are you masking in Track 1 (i.e., How is the yellow in Track 2 showing through to Track 1)? And how is Track 3 showing through both tracks (if it is)?
-
That’s a great point, John. The whole nested project thing is killer, for certain, and endlessly useful (I use it for all of my program graphics, overlays and whatnot). So, yea, read my response more as a workaround for those times when Vegas is giving you a hard time (crashing on a complex composite, hanging in the middle of long render).

That way might work Graham, but I can’t tell without more details.
And I don’t have an easier way, but a much harder method (which seems to be how I do things in life!). See the attached image, but a basic summary is:
1. Do your secondary-color-correct inverted mask desaturate trick for one color – Let’s say BLUE. (I assume from the OP that this is what you are doing. Whole slew of details glossed here in step one – I can elaborate if anyone cares.)
2. Create a mask: Duplicate the track and, in the higher track, go back into the Secondary Color Corrector and de-select the Invert item and select Show mask only.
3. Change the Compositing Mode on the new mask track to Multiply (Mask) and then hit the Make Compositing Child button on the lower of the two tracks.
4. Re-add the clip to your project, repeat 1-3 for another color, say GREEN.
5. Re-add the clip to the lowest track and desaturate it completely.So we’ve got:
Track 1: Mask and Parent to…
–Track 2: Secondary Color Corrector BLUE
Track 3: Mask and Parent to…
–Track 4: Secondary Color Corrector GREEN
Track 5: Black & White clip__________
Imagine what it would be like if TV actually were good.

Yes. QuickTime ANI. Yes.
Hehe.
You can definitely pre-render chunks to a lossless codec (like QuickTime ANI or PNG (24-bit)). I do it all of the time on complex projects, since it seems like if anything is going to make Vegas cranky, it’s a complex project + a modern H.264 VBR distribution codec. I usually bring my pre-render video-only files into my main project on top (not sure if you’ll have enough tracks to do this in the trial version), save a new version of the project and use the original audio track. This gives me some flexibility to make changes (e.g., you can always poke holes in the “raw” files to get at lower layers to fix/adjust something). You’ll get humongous files, but in this age of 10-cent/GB HDDs, that’s usually not a problem. And, yea, your trial version VEG files will open in the retail version.

Hehe, yea, well, if it’s any consolation, I’m not entirely sure scrolling would make subtitles any more readable and might have even made them less readable. I can’t remember the study right now, but I seem to remember scrolling text taking twice as long to register in the brain and being something like 15% less readable overall. Or something. Don’t quote me on that. Anyhow, you wouldn’t have known if you liked it until you tried and that’s a moot point now!

True subtitle overlays (and menu overlays for that matter) as a part of the DVD-Video spec are very limited and really can’t be very fancy, so it’s not really a feature that can/can’t be in an authoring app. In other words, sure, you can add scrolling subtitles to the video in Vegas like you would any other titles, but hot when adding true subtitles to a DVD-Video disc of the sort that can be toggled on and off.
I think you can add a CC signal to the video on a DVD, however, although I have no idea how to do that.

I haven’t tried Blu-ray, but I have a close personal friend (*ahem*) that pulls clips from DVDs often enough (to cite as examples in videos) that your symptoms sound familiar. I agree that it seems like at least part of the problem is the duration of the clips: even 1GB MPEG-2 files can take a minute or more to load and will sometimes crash. I’d also guess that the audio is often the problem, more times than not (multiple language channels, etc.). My pal has even discovered that Vegas 8 under WinXP is the most reliable combo for this task (Vegas 8 or 9 (32 or 64) + Vista64 just won’t open some VOB files).
* BTW, not to derail the conversation too much and without speaking to specific cases, using clips as examples and remixing can be covered by Fair Use. It is, however, unquestionably a violation of the DMCA to rip Blu-ray and defeat CSS on DVD-Video discs. The MPAA recommends that you use your camcorder to record the screen, which will unquestionable work in your situation: here’s the MPAA’s video explaining how to do it.
