Help rendering render 1440x1080 properly

I am having a lot of trouble with my 1440x1080 footage and I'm desperate for help.

My camera accidentally recorded at 1440x1080 instead of the 1920x1080 that I usually use. The original footage looks fine, but I am having a terrible time figuring out how to export my footage so it doesn't end up looking like garbage. I've tried tons of advice I've found on the internet (and in this forum) but none of it results in footage that looks anything like the original.

In order to show the problem, I used VLC to take snapshots of the footage. They both look okay! I had to take an actual screenshot for the difference to be visible.

Original footage:

Screenshot of footage exporeted from Premiere Pro:

When the video is in motion, there is a weird pixelization around people when they move. The edges are all rough and blocky.

I have tried exporting this in so many ways. What am I doing wrong?

Also, here are snippets on YouTube of both the raw footage and rendered using the "Match Highest Bitrate".

Any help would be amazing. This has confused me for hours.

Repyling to myself with a new idea:

Here is a short clip of test footage we ran when setting up. Maybe someone can fiddle with it and figure out what I'm doing wrong.

Thanks again to everyone with their help. I can't tell you how much I appreciate it.

Ok, based on this, I made a mistake in that earlier preset I sent. I neglected to change the output to Progressive (as opposed to upper field first). Here's a link that has a revised preset, and an output of the "00000.MTS" file run through Media Encoder with that applied. If the MOV file I've uploaded exports ok from your edit, you should be able to just run all of your footage through Media Encoder with that preset applied. (Reminder that you'll likely need to change your sequence settings to match up with the settings of the MOV; or just create a new sequence from clip to see if it works).
Theoretically should resolve issues with the 1.333 pixel aspect ratio and interlacing.

There has to be something wrong with my system, either my Premiere or my actual system.

Your render came over 100% fine. Looks just like the raw footage. I used your preset to do the same thing and I get this:

It's so frustrating.

To troubleshoot things, I rendered a new video from your output and it came out perfect. I also rendered a video from a prior year (it's an annual event) and it came out perfect. There really is something about this video format and my system or version of Premiere.

This seems like an absurd question, but would any like to help convert these for me? I'm at the end of the rope. I did these for a nonprofit event I care a lot about and I can't upload this mess. It's awful.

In total, I have 16 videos, running 18.2 GB, and a total length of almost 5 hrs. It's a lot.

If no one can help, please know I really do appreciate everything everone has done. I'm sorry we couldn't figure it out.

You don't say what framesize you used for both the sequence and the export. As if you are changing framesize, then the method of interpolation/blending is something to be aware of.

So ... what are the actual specs?

First, thanks for replying!

Next, framesize. Please let me know if this helps. When I check the properties of the raw footage in Premiere, here what I get:

Type: MPEG Movie
File Size: 1.06 GB
Image Size: 1440 x 1080
Frame Rate: 29.97
Source Audio Format: 48000 Hz - Compressed - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Total Duration: 00:16:20:15
Pixel Aspect Ratio: 1.3333
Alpha: None
Color Space: Rec. 709
Color Space Override: Off
Input LUT: None
Video Codec Type: AVCHD H.264 4:2:0

I've tried exporting it in about five or so formats, both to specific presets and modified presets, and they all turn out similar to the sample video. Let me know if you need any of those details, as well.

Again, thanks!

PAR of 1.33 is not surprising with that framesize. Gave you checked that the PAR out is the same?
