I frequently render 2-3 hours long interviews sessions for clients without any problem. This is from AVCHD rushs to SD DVD however. I did not yet done it for HD-DVD.

I would never go to the hassle of breaking everything in short parts.

Shure, very long SD to SD renders do not cause any problems also.

~2 hours. but normally long stuff is more editing vs FX. The short stuff normally is more work.

Mike the couple could be divorced and the clip is still rendering

What I want to know is how many changes back and forth for a 30 second TV billboard PAL after sign off in one day, mine is…. 5
And 2 days later the clincher …the client was running it in cinema's.. ..hey its cool but like it’s a bit blurry and blocky???

I've done a few 8 hour long projects, but do 4hr projects more regularly. Haven't done anything longer than 2 hours since moving to Vegas 9 though.

Just for the heck of it one time i combined three movies i enjoy into one single file. They actually run as a continuous story so i wanted to cut out the credits & titles inbetween so that i could experience it as one continuous running sequence. The result was about 7 hours. No hitch at all, though that was probably back in Vegas 3.

A lot of the local theatre productions can run about 2.5 to 2.75 hours. There's never any issue with those. Of course, in these cases i tend to have fewer than a half-dozen events on the timeline. I've done these will all versions of Vegas, up through 9.0b (haven't had one since 9.0c came out). The longest one was about 4 hours, which was edited in Vegas 7.

More complex projects with hundreds of events probably tend to be under an hour for me, but even still that's way over 15 minutes.

I think it has more to do with the complexity of the project than the length .I did a couple of plays for people, easy edits and about 1 hour and a half, no problem. Lots of edits, different sources, plenty of CC and my ability to render stuff that is 10 mins long or so goes out the window.

Until....
I tried Blink's memory hack. Made my most complex renders go smoothly, and I have not noticed any other adverse side effects. Yet....

My personal experience is this:

1. If a currently used Vegas version/OS version combination is stable for my single clips of the format I'm currently using (like the XDCAM EX 1080/25p),

2. Then I have no problems whatsoever editing and rendering even a 2hour + project, with quite a lot CC, compositing, titling, etc etc.

The big problem is the "if" part in point 1, though:(

Vegas can handle long renders with no problem, I have done 2 plus hours several times with a variety of different levels of vfx, cuts, media types etc.

Over the years if there was a hang up, I discovered that it was a RAM issue (fixed) and if you remember the old single core Athalons, they used to have a heating issue.

Just my two cents,

I routinely go 3+ hours with multicam and up to five audio tracks.

I have found if I save, close, and re-open every couple of hours during editing, and again before rendering, the process goes quite smoothly, and free of "surprises." Having the recent project backups doesn't hurt a bit, either.

Just worked on a seminar project where each day has about 12 hours of HD video on a multi-camera shoot edited in Vegas 9c down to 7 hours.

I work on projects every week from 2 hrs to 8hrs long. I have had no problems with 64bit V9.

The longest project I ever did was a seminar that was 8 hours long but it was an easy multicam edit.

The longest render I ever had was 3 days and some change and it was when I was using 3d track motion extensively in a project along with some pretty lengthy fx chains.
