Blu-ray Challenge: How to take a 30fps video to 24fps, encode in HD on Vegas 8 Pro, and burn Blu-ray on a Mac.

[Angelo Mike] “Like John said, you could de-select “disable resample” as well. I might disagree on him there, if only because for the last five months I’ve rendered out 24 fps footage from 30 fps by using “disable resample” before rendering, and the footage looked fine.”

It’s probably good to point out when you would and wouldn’t disable resample. If your pans are slow enough, you can disable resample and still get smooth motion. The problem with 24p is that it’s not a multiple of 30 so you can’t just drop every other frame and have the motion look consistent. You must drop every second frame, then every third frame, then every second frame, then every third frame, in a 2:3:2:3 pattern. This is what could make the motion seem jerky. Of course, the blending of resampling could look worse if there is high motion so it’s a judgement call. I like to keep Smart Resample on and only turn it off when it causes problems.

I wasn’t aware of that. Noted. I always did this on videos where I have a stationary camera and someone talking in front of it, so I never noticed any disruptions to motion.

Dunno if my last post went through. I tried ‘smart resample’ and my
render froze at 16%. Anyone know why? I’ve had to resort back
to ‘disable’, just so I can have a file to work with tomorrow.

Update on my update –

with settings listed in post, i tried a file with everything
set to ‘disable resample’ and that version crashed too! Stopped
at 61% – does anyone know why i’m having crashes when I try either
disable or smart resample?

(new info – wednesday evening, 13th) – was able to load my timeline into
a new .veg and render out another working copy of the movie with
‘disable resample’ checked. Tried ‘smart resample’ after and the
render got stuck again at 17%. So, I’m not able to test smart resample
yet. Anyone know why this is happening?

(in response to John’s settings)

I used all the settings that you recommended and got a pretty
good looking Blu-ray copy. Some footage still seemed a little extra bumpy than I remember it being when I screened the film SD on a projector last year, but I just watched it on a 20 foot theatre screen on Blu-ray, so that may be why i’m more sensitive to the bumps in my
camera movement. But i’m still investigating.

I left the disable resample on for the first render because some of
the pans are fast, and/or shaky. For tomorrow’s screening, i’m going
to have everything set to “smart resample” as you recommended and I’ll
note the difference (not able to yet…..)

Something I wasn’t sure on. My project properties are set to: Field Order: Upper Field First and the Render settings to: Field Order: none (progressive scan). Is this problematic, likely to cause any motion
issues? I left Upper on the project settings because you didn’t mention i should change it. nor did I change from Gaussian on project settings. Are these both correct settings for my particular project?
