While EXRs have been used by VFX houses internally for years, the adoption of delivering EXRs for final DI in my experience has been relatively new (meaning the past couple of years). For VFX vendors delivering OpenEXR, what compression types are supported under the ACES container?
I thought I had read somewhere that only three compression types were allowed as the ACES container is a subset of OpenEXR:
- NO_COMPRESSION (file is not compressed)
- PIZ_COMPRESSION (lossless)
- B44A_COMPRESSION (lossy)
A common form of compression used with Nuke and VFX facilities is ZIP (1 scanline). Some DI houses support this and others don’t.
Any concerns with delivering ACES2065 material as EXR with this type of compression?
