aspect ratio question(s)

Postby seasons » Wed Jul 07, 2010 3:46 pm

I'm having some problems with my video's aspect ratio, which I can't seem to control for some reason. I've tried to follow the guides as best as I could, but possibly due to the weird nature of my video, it doesn't seem to offer up any solutions. I guess I know how to control the aspect ratio just fine, it's just keeping everything inside the frame looking as it should be that's my problem.

I'm editing a 4:3 source, cropping it to 16:9, and then upscaling it to 848. I know, lots of editors hate this but I need to do it to make my video elligble for a MEP. So I'm not really looking for the pros and cons on upscaling, but rather, how to keep my aspect ratio correct. This is really one of the biggest n00b questions ever, I'm sure, but I'll go ahead and dump some screenshots anyway and hopefully someone can help.

Here's a screenshot my original video, still interlaced, in DGindex:

It's supposed to be a perfect circle, although due to PAR issues (?) it's more of a stretched-out oval shape. So I de-interlaced, cropped, and resized it with this script:
MPEG2Source("C:\Users\Preferred User\Desktop\DGIndexProjectFiles\CL3.d2v", CPU=4)
AMVDeint(mode=0)
Crop(0,60,-0,-60)
Spline36Resize(848,480)
ConvertToRGB32()


and it comes out looking much nicer:

Here's what it looks like while I'm editing in Premiere:

I finish my video, save and export it. My lossless file comes out looking like this:

What steps did I need to take in AVSP to get a final, lossless video with the correct AR? Or, what can I do after exporting to correct this, and still keep my video lossless?

Based on what I'm working with (a 4:3 source) and what I want the final product to be (16:9, 848x480), what should my project settings be in Premiere?

I've been editing on and off for over a year now and I thought I had a good grasp of the basics but the more I try to figure this out on my own, the more confused I find myself getting and the less enjoyable the whole project slowly becomes. I don't want to turn in what's at this point, still a flawed video if there's a chance that I can do it the right way first. Any help on this would be really appreciated.

You want to resize it like this:
Spline36Resize(848, 576)
Crop(0,48,-0,-48)

And make sure your editing stuff is set to square pixels.

Should there be a setting for it in Premiere? I'd look for it myself but I'm at work now. Ideally I'd like to always be editing with Premiere set to WYSIWYG, pixel-wise.

Thanks for that script, I'll try that tonight, too.

Yea, its both in the project settings and the export settings. If you dont make sure they are both set right, you can get some weird stuff. (and it DOESN'T do square pixels by default, im pretty sure)
