Mixing ARs...

Vivaldi · Post by **Vivaldi** » Mon Jul 21, 2008 5:18 pm

Hello,

My problem (aside from ineptitude) is that I've got a source with different ARs. Now, I've got my DVDs, which should be 720x480. That's all well and good, however, there are a few cases where I need to use raws (series hasn't been fully released, and it's a fricken long series anyway.) The problem, one set of early 4:3 episodes is 640x480, and a later 16:9 portion is 1280x720, >_>

My question, is is there any effective way to make it all 16:9 without losing a vast amount of quality\footage. And if so, how would I need to crop\resize to make it work.

Now, I realize that this problem stems directly from using raws, so I understand if you wouldn't want to help. Do know though, that I'm doing it out of necessity, not apathy, and that I fully understand how much it's looked down upon.

since some of your source is 640X480

I'd probably suggest resizing the 16:9 footage directly to 640X352 (or 360 if must :\ )
LanczosResize(640,352)

And putting you project settings (this works in premiere) at 640X352 and then you can just move your 4:3 footage up or down (if needed) to get the most out of a picture.... this saves croping episodes individually.

You want to avoid upscaling that 4:3 footage if possible.

There are a lot of different ways to approach it tho, and it all depends on what you want the end product to look like (16:9 or 4:3)

if you were mixing PAL & NTSC ratios then I'd suggest something different.

What she said, but I guess 704x400 could be better... you get to loose less detail on your HD footage and it's not that big of an upscale for the 640x480 footage.
