Time Lapse - some pointers and a question

Hi all,

I just joined (so I hope I'm posting OK).

I have been doing time lapse photography, "tapeless", by using the VX2000 along with a laptop. I've done excellently in getting as close to ideal "captures" and processing of 4:3 in native "rectangular pixel" 720x480 format still images. I've made a page with some tips (and a really small time lapse example here):

www.geocities.com/tracey_pooh/DumbBunnyProductions.htm

I indicate some good ways to get the stills in DVF format and all the way through Premiere and into AVI without leaving rectangular pixels.

My only stumped part is doing the same for 16:9 still images. I can get them as 720x480 DVFs, and get them as 720x480 BMPs into Premiere. However, my version of Premiere 6 LE doesn't seem to be interpretting them in "D1/DV NTSC Widescreen 16:9 (1.2)" pixel aspect ratio, and as the 4:3 "0.9" aspect instead. Any thoughts or help is greatly appreciated!

Answer! An answer in a related thread that got me down the right track...

For my 16:9 BMPs, my Premiere version defaults to think the BMPs are in 0.9 mode and not the correct "D1/DV NTSC Widescreen 16:9 (1.2)" pixel aspect ratio (where 1.2 I'm pretty sure refers to horizontal scaling 720==>852, where 852 / 720 = 1.1833333 (or about "1.2")).

Thus, they would get resampled and distorted. However, thanks to DV Forum hunting, I found the way to make Premiere interpret them correctly.

When stills are on the timeline, select all of them. Go to "clip" menu, "Advanced Options", "Pixel Aspect Ratio...". Select "D1/DV NTSC Widescreen 16:9 (1.2)"

There you go! Your entire "capture to export" workflow is now using 16:9 widescreen "rectangular pixels" and you are free to have as smart or not-so-smart AVI converter figure out where to go from there.

I have more thorough details, my setup, etc. here!
