Convert 1440x1080 to 640x480

[gkbandit]

2 cameras, one was set for 640x480 4:3, 30fps, and the video camera was set to 1440x1080 (1.3333) 29.97fps. The goal is to get build them as into one video clip without stretching the clips out of proportion and without letterboxing. The end product will be DVD or DVD widescreen if possible. Can anyone offer guidance on how to accomplish is?
Thanks

any modern editing software. what are you using?

The goal is to get build them as into one video clip without stretching the clips out of proportion and without letterboxing. The end product will be DVD or DVD widescreen if possible.

I'm confused. How do you propose to display them widescreen (16:9 I presume) without either pillarboxing or cropping them top and bottom if you want to maintain the original pixel aspect ratio?

Can I use Adobe Premiere Pro CS6?

[aedipuss]

sure but like slipster said all your wishes can't come true. widescreen and fullscreen can't mix without black bars.

1440x1080 is an alternate HD imaging resolution to 1920x1080. Whereas the former has a PAR of 4:3, the latter has a PAR of 1:1. Both have a DAR of 16:9.
And like what was mentioned above, you can't combine this with your 640x480 4:3DAR footage without having one or the other either cropped, padded (letterboxed/pillarboxed), or stretched/shrunk anamorphically.
You also will have to make a compromise about the resolution - you will either have to compose for HD or for SD.

If I understand correctly I need to crop the 1440x1080 to 640x480 and save that cropped footage as 4:3fps. Can I do the cropping and converting with Premiere Pro?

[smrpix]

You can do all sorts of resizing in premiere pro, crop, pad, change aspect ratio. A lot of it will produce artifacts (such as downscaling the probably interlaced 1440x1080.) The other issue you have to deal with is mixed frame rates. Is the 30fps material truly 30 or 29.97?

Premiere can mix and match but the results often aren't pretty.

You can do it in premiere. Essentially what you are doing is cutting out left and right sections of the active picture area - you will lose some field of view (making 16:9 to 4:3) , then scaling it down fit SD dimensions

Use a 720x480 NTSC DV Sequence timeline settings (4:3) . You're making a 4:3 DVD, not 16:9 widescreen.

For 1440x1080 clips, use the scale parameter (in the effects control panel, twirl down the menu under "motion") and scale it down until it fits the window without borders . If you have "uniform scale" checked, it will do it
proportionately .

640x480 clips are already 4:3 and should "fit" perfectly already

Use the same settings for DVD export in Adobe Media Encoder (NTSC DVD 4:3) , then use those assets in your authoring program, encore or whatever you are using to make the DVD




16:9 clips are likely from interlaced HDV camera (you can confirm this) . Note older versions of premiere did very poor quality interlaced scaling. It's improved in CS5.5 -CS6, but it's still not stellar . Many people use avisynth and the HD2SD script from Dan Issac (use search, it can be found on Adobe forums) . Or other interlaced scaling methods either through avisynth or vdub

Yes poisondeathray following your instructions works...thanks for the info. As far as whether the footage is interlaced I'm not sure how to check that.

[poisondeathray]

It should tell you in the clip properties . It's not going to affect what you do if you're happy so far

But if you're curious as to what you might be missing , use those search terms, there are a bunch of comparisons and articles discussing premiere's poor scaling (especially interlaced scaling)
