This could be a huge deal for anyone working on video codecs or display tech. Finding legally clear, high-quality, uncompressed (or mezzanine) 4K HDR footage to test encoders against is surprisingly difficult. Most test footage you find online has already been stomped on by YouTube or Meta compression.

Having the raw EXR sequences and the IMF packages for Sol Levante and Meridian means researchers can finally benchmark AV1 vs HEVC vs VVC using source material that actually has the dynamic range to show the differences. The fact that they included the Dolby vision metadata is the cherry on top.

Don’t most camera manufacturers (like ARRI and BlackMagic) have test footage for their raw and/or log formats on their websites? Here’s ARRI’s (which includes ProRes in addition to their proprietary formats) https://www.arri.com/en/learn-help/learn-help-camera-system/...

I used to work at a company developing an independent H.264 decoder implementation. We would have killed for this kind of source content, especially if the license allowed showing it at trade shows.
