Colour shifting on Exported video.

Thu Apr 08, 2021 8:19 pm

Hi,

Whenever I am exporting my videos, if I use a deep blue colour it doesn't export properly--instead it the colour shifts to more of a purple. I cant figure out why this is happening. Attached is an image that shows the video in Magic before exporting, and on the right is the video after being exported. You can see the blue at the top and bottom of each video, is different. I'm wondering how I could fix this or stop this from happening when I export?

Thanks,

Allinesik

Image showing the colour differences. The image on the left is before export, the one on the right is after.

I picked your blue and rendered it from Magic to MP4 and the colour shifted a bit (~ 3%). Have you tried different file formats?

I've never been too concerned about slight colour shifts since the projector and environment does a lot worse.

I am not 100% sure, but I know that the lower-quality codecs can do this to a certain extent, particularly the mp4's that use a 4:1:1 colorspace. They consolidate some colors in order to increase compression.

If you want better output quality, use Apple ProRes, or for 100% pixel-for-pixel perfection, use a PNG sequence.
