Severe Pixelation on PNG with Motion After Rendering (Premiere Pro)

[FOediting]

I'm experiencing severe pixelation on a PNG file after rendering in Premiere Pro.

• The PNG has motion graphics applied (Ease In/Out + Scale).
• In the timeline preview it looks perfectly fine.
• After rendering, the image becomes pixelated (see attached before/after).
• I tried exporting the PNG separately, nesting it, and re-importing — no difference.
• No additional effects applied, just basic motion.

No clue what is causing this....

The pixelation in my rendered PNG image was caused by the default low-resolution preview settings in my sequence.

After changing:

Preview File Format to QuickTime

Codec to Apple ProRes 422 LT

Preview resolution to match my timeline (3840x2160)

And enabling Maximum Bit Depth and Maximum Render Quality

...the issue was resolved. My preview renders are now sharp, and exports using "Use Previews" look clean.

Leaving this here in case others run into the same problem!
