After Effects + Media Encoder, MP4 Colour bug

Hi Guys, 

There is a Colouration Bug we have noticed when it comes to composition sizes. This has been been an issue for every MP4 / MOV we export. Most Noticeably MP4 Conversions rendered from After effects & rendered from Media Encoder.

The Colour bug we noticed is anything exported at a Pixel height of 500px exports a different colour. However when we enlarge this aspect ration by 2x/3x it exports the right colour.

PLEASE NOTE , Both exports are the same colour profiles, same colour management, same everything.

We tried sRGB Setting, ROC 709 Setting, Exporting through AE, Exporting through ME,

Exporting as a MOV through ME (fixed the colour but stretched the banner to fit 1920x1080)

We exported put 600x500 & 1600x1000 on a 1920x1080 composition and exported which fixed the colour however when we take it into photoshop to crop the video to its original size (600x500 & 1600x1000) it saves out this off orangish again.

So far the only thing that works so far is if we expand the composition size 18-20% above the 500px height threshold. (same aspect ratio)

Please find the Examples attached.

This was an Issue in After Effects and Media encoder 2022 & is still an issue in AE/ME 2023 Versions.
