Since many of you helped save me countless hours I wanted to share what took me hours to figure out to improve output quality. Trouble started when I output a current project to DVD and there was a tremendous amount of interlace flicker and some aliasing. The main problem is the fact that greenscreen footage was shot on a 4:3 camera and the project was destined for 16:9. Maybe this approach will work for you. You may disagree with my approach, but I spent many hours trying all sorts of different approaches, this worked best for this project.

You'll have to forgive me but I don't have time to write what the previous settings were. Additionally, I've added my export settings for a flash .flv.

Vegas (6a):

Make sure to uncheck “3 2 pulldown removal” in Vegas “Preferences”

Vegas Project should be 873x480, progressive, 24fps, 1.0 (square) pixel ratio, Quality Best, Blur Gausian, Field Blend

Note: Vegas Chroma Keyer setting, R=0 G=255 B=0, low threshold 0.690, 0.969, 0.060. However, this setting will be different for every shoot.

Note: The reason for the square pixel aspect ratio to produce a widescreen film is the quality loss when I place a 4:3 24p DV footage (from pro-sumer Panasonic camcorder) on a Vegas Widescreen project. I got lots of flicker, jaggies and artifacting. The video imagery was interpreted better with the project being 1.0 (square) than 1.21.

For DVD:

Render out of Vegas as DVDA 24p Widescreen 23fps 3+2

Render out AC3 audio

DVDA:

Make sure “allow 3 2 pulldown is checked in DVDA “Preferences”

Set project as Widescreen. Place video in project, double click it and make sure “reduce interlace flicker is” off

For Flash Web Video:

Render out from Vegas as Quicktime (Pro) .mov with same Vegas project settings

Then export .mov as .flv with settings:

VP6 Data Rate 550

15fps Resize

custom 600x338

60 32kbps (mono)

audio
