24p effect in Vegas??
I rave about Vegas constantly, especially when compared to Avid Xpress. However, in addition to having a much better titling tool, support for Boris plugins (and others), and playing sound out with firewire preview…. it has one effect that Vegas seems to be missing: 24p conversion of 60i video. Avid has the “Fluidfilm pulldown” effect that does a very nice job of converting 60i video to 24p cadence. I have 30 minutes worth of symphony concert footage edited together that I want to apply this effect to. Right now I have to render an AVI, import into Avid, apply the effect, render effect (and HOPE I don’t get error messages), print effected video to tape, capture in Vegas, and apply to timeline. I’ve read that some say to change the “undersample rate” on the clip to .8 and turn on “reduce interlace flicker.” Another setting to change would be the clip properties to progressive. But this produces very bad unusable results. There has to be an actual effect that would do this. Anyone have any clues about this? Thanks!

Unless I am missing something in your question, the answer would seem to be that you render using one of the several 24p options under avi.

Good suggestion. I just tried this a moment ago, and while it does yield a 24p file, it’s not quite the effect I’m going for. With this method, there seems to be way too much blurring or field blending (especially with fast motion in the frame). The Avid effect has nice sharp frames with no blending or blurring. In some ways, the output looks better than our DSR-450 camera on its 24p mode. It’s hard to describe, but it really adds a richness to the picture without causing any interlacing, blurring, or blending issues. It does have its drawbacks though. Sometimes there’s a bit of distortion during a cut or dissolve, and other times there may be a bright spot in the picture that becomes pixelated. Not sure why this is.. just the nature of the filter I guess.
Any other thoughts? Surely there are folks out there that want the film cadence of 24p applied to 60i video. I have the Magic Bullet effects, and as great as they are, it still looks like 60i video when it’s done. Thanks for the suggestion though. I’ll keep fiddling with it as well.

You’ll want to shoot with your shutter at 1/60 of a second. This translates beautifully to a 24p cadence. Vegas will easily convert 29.97 fps footage (commonly referred to as 60i) to 24p, which is actually 23.976 fps. This creates the cadence of film, where during the process essentially 6 frames/12 half-frames per second are removed from the stream. Before starting your project, open the File>Properties dialog, and choose the NTSC 24p option in the dropdown. Press Apply to close the dialog and apply your changes.
Now import your 50i or 60i media to the timeline and begin editing as you normally would. Rendering titles, generated media, etc will all be correct with the new algorithms. No longer is the uncompressed intermediary needed! In case it’s not immediately obvious, to print this to tape requires a camera or deck capable of receiving a 24P stream. You’ll want to render by going to File>Render As> and choosing the NTSC-DV 24p (inserting 2:3:3:2 pulldown) Be sure to use BEST mode when rendering! (default is “good”)
This technique is most valuable for printing to DVD, Render the project out using the Vegas 24P NTSC or PAL template, you can render as a DVD Architect NTSC/PAL video stream if you intend on rendering an AC3 file for the audio, or render as a 24P NTSC/PAL file where the audio will be packaged with the video stream.Thanks to a well known Vegas Guru for this info.
