16:9 HD to 4:3 SD?
Hi All,
I have rather large .avi files that I am trying to make into mpeg2-dvd files. The .avi files have the following specs:
.avi, mjpeg codec, 16:9, 1920×1080
These .avi files are actually 4:3 movies that have been letterboxed. So I want to export 720×480, 4:3, mpeg2 video files, removing the letterboxing for the final DVD. (most of these DVDs are being watched on older, CRT television monitors)
It seems that when I crop the sidebars off the video in the media exporter in Premiere and change the aspect ration to 4:3, the video becomes really small in the output (it appears both letterboxed and pillarboxed). I have to check the “fit to scale” box for the video to re-fill the screen. This doesn’t seem right because it appears that Premiere is somehow down-resing the video and then up-resing it again at a lower quality.
I guess my question is, why would I have to check the “fit to scale” box if my original image is 1920×1080? Shouldn’t the media exporter be cropping the video to 1440×1080 and then scaling it down to 720×480 and hence make checking that “fit to scale” box unnecessary?
Thanks Jack

Are the videos letterboxed or pillarboxed?
Either way, uncheck “fit to scale” and do the resize manually with Effect/Distort/Transform.
At export, make sure to change Recompress: Maintain Data Rate to Recompress: Always.I like to control every setting I can.
Make sure you’re in a Full Screen DV project file. If you’re not, just create one and import your original project into it.
I think “fit to scale” might be a default, but I wouldn’t recommend using it. It just uses basic rendering to proportionately scale whatever you drop into the timeline, so it fits in the projects dimensions.
Effect/Distort/Transform resizes with a higher quality.This is all assuming you don’t need to deinterlace anything.

Thank you!
You are making me think the problem is with my initial project presets. Even though the video is 1920×1080 (the image is a 4:3 pillarboxed image), should my presets for the project be NTSC – DV > Standard 48khz? That way, when I import the 1920×1080 asset, I can manually scale it down using Effect/Distort/Transform to fit the NTSC – DV preset. I was using project presets that matched the specs of the original file. Instead should I use presets that more closely match my desired project output?Are the videos letterboxed or pillarboxed?

I always create a project that matches my desired output, even when I need additional renders at smaller sizes. Different size, different project file. That’s just how I do it.
It’s good that you have a project file at full resolution, just drop it into a DV project, resize it, output for DVD.
As long as you’re in an NTSC region, then yes, NTSC DV. The audio sampling rate also depends what you need in your workflow.

I’m doing something similar. I shoot on a Canon 5D but my client asks for 1440×1080, which I know is backwards but it’s going into a mobile app interface.
I easily figured this out in AE and really like the way it works and can be moved around easily but the rendering is so slow.
If I can do it all in Premiere, I’d be happy.I’ve noticed in FCP, it just does that gross smushy thing.
thx

Hello everyone!
This is my first post, please forgive me if this is not the right place to write this:
I just recently had an issue that was quite pesky with a client who needed to edit video for an installation piece. The original material was shot on a Canon 5D Mark III and the final output needed to be in Apple ProRes (LT) 1440×1080 with 4:3 aspect ratio. I work in Adobe Premiere Pro CC and for the life of me couldn’t understand how to export it correctly. The videos always showed up in VLC and Quicktime as 1440×1080 (1920 x 1080) maintaining the 16:9 aspect ratio even though I chose Anamorphic 1.333 (under the assumption that was correct for 1440×1080)
I went over this many times and finally it hit me that in the export dialogue to change the aspect ratio from 1.333 to square pixel and then “scale to fill” and then it all worked out.
