  Writing to Blu-Ray – Color Issues

  Posted by Yaz Rabadi on February 8, 2012 at 1:06 pm

  Hi all,

  I’m experiencing some colour issues while burning a short film to Blu-ray – hoping you guys can help me out! I’ve tried two methods – here are the workflows I used:

  In both cases, I exported out a 10-bit uncompressed QT file from Adobe After Effects (Format: Apple FCP Uncompressed 10-bit 4:2:2, 1920 x 1038, Millions, 16-bit Integer (Little Endian), Stereo (L R), 48.000 kHz). In After Effects I was working with a 10-bit uncompressed QT source on a 32-bit sequence. Rendered the 10-bit out in full quality at Trillions of colours – as a QT on the mac, the rendered file holds up very nicely.

  Here are the workflows I used for creating the blu-ray files:

  WORKFLOW 1: Using Adobe Media Encoder, I exported to Blu-ray H264. Average bit-rate at 33 and max at 35. I used the max quality render settings and ended up with a .m4v file and .wav file. Burned these to Blu-ray using Adobe Encore.

  WORKFLOW 2: Using Compressor, stream usage Blu-Ray with a format of MPEG-2. Average bit-rate set at 33 with max set at 38. Used Dolby Digital Professional (auto) for audio. Once again, I used Adobe Encore to burn the blu-ray.

  With Workflow 1 I found lot’s of colour issues while playing the disc. Mainly I found faces to contain a lot of red pigment and colour patches on certain images – it didn’t look to pretty. I tried Workflow 2 since it was MPEG 2, and felt this worked a bit better – less patches colour patches and things held up a bit better, but still found lot’s of red/warm pigment in skin tones.

  Is this natural? I’m new to the world of blu-ray writing, so maybe I’m just not familiar with all this. I’m just trying to achieve the best quality I can with the blu-ray outputs.

  Any suggestions, ideas or tips would be greatly appreciated.

  Thank you.

  Here’s a still I snapped off the blu-ray playback. Apologies for not being able to get better quality, but you can see the red banding all over his face. I’m not sure what the deal is – tried exporting through compressor and AE with various Blu-Ray formats, and am still getting this every single time. It’s not present in the source file, so I’m really puzzled as to where this is coming from.
