SD Footage Upconversion on HDV Timeline

michaelshive wrote on 9/18/2006, 6:03 AM
I was working on a 720p project yesterday and threw some SD footage shot on my DVX-100 onto the timeline. Unlike Vegas 6, the new version of Vegas appeared to upconvert the SD footage so that it filled the screen vertically (black bars on each side) and it actually looked really good (no pixelation).

Am I missing something here? Is this just an anomaly or did Sony do something to enhance SD footage in HD timelines in Vegas 7?

If you've got a 16:9 project and put 4:3 media in it then you get the bars on the sides, always been that way with everything, certainly Vegas from V4 when I got on board.

If you're working in PAL then 720 isn't a whole lot more res so good SD doesn't look too shabby. However letterbox your 4:3 SD to 16:9 and things get a bit messy.

Yes but in previous versions it would also letterbox the top and bottom as SD footage is only 720px vertically and 720p footage is 1280px vertically. When I dropped this on the timeline it defaulted to stretching the 720 to 1280 and - myabe my eyes are just fooling me - it looked so good I thought there must be something going on in the upgrade to explain this.

Isn't there a "Stretch video to fill frame - do not letterbox" setting somewhere in Options?

I think you meant "horizontally." 720p footage has 720 lines and is 1280px wide. For SD footage the 720px is width, not vertical height.

yup

in event pan crop, u can stracth to fill frame. or not... u cal also match output aspect (which DOESNT mean the clips aspect is actually being changed.. it means the clip pan and crop is emulating that aspect... u dont want to change the actual aspect of the clip, just the OUTPUT of the clip... else youll get jaggies all over the joint...
