Exporting from a YUV codec (DvcProHD 720p) into Animation, causes the white point to clip.

Lowered it before export to prevent clipping: [

Exported it with a lower white point and colored it in case the RGB mapping was confused with having too much similar colors, but this still clipped at a lower white point of around 70% on the scopes: [

I was curious and decided to lower the shot down to 50%: [

Work around to this is to color correct it to broadcast safe, export it in Uncompressed 10 bit (to keep within YUV space), and reimport it into the timeline, then export it as Animation.
Similar issues exporting via QT conversion or Compressor. Switching the timeline to Animation clips the footage instantaneously.
