OPEN SOURCE CONTENT
At Netflix, we are always exploring ways to make our content look and sound even better. To provide a common reference for prototyping bleeding-edge technologies within entertainment, technology and academic circles without compromising the security of our original and licensed programming, we've developed test titles oriented around documentary, live action, and animation.
Many open source assets are available from each project listed below. Our hope is this will encourage more experimentation, learning, and discovery that will benefit the whole industry. Many of these titles are also streaming on Netflix and are best enjoyed with any HDR configured device with your Premium subscription.
You can download single files directly through your web browser, but for large files and long frame sequences, you may wish to use command line tools. Guidance is included below. Ad Blockers may cause errors in your downloading process, so try turning it off if you have issues.

Sol Levante (2020)
We’ve had great success remastering titles like Knights of Sidonia, Flavours of Youth and Godzilla from SDR to HDR over the last few years. But what if we increase the resolution and create anime with HDR in mind from conception? Working with Japan's Production I.G, we set out to create the first 4K HDR Atmos anime short and discover what would need to change in anime workflows.

A live action test piece, Nocturne was shot at 120fps and sought to investigate footage with spatially complex scenes that mimic other professionally generated content to challenge codecs on both the encoding and decoding sides. This piece was also mastered in Dolby Vision and Atmos.

Upon noticing the contrast in dark shadows against the bright sky and sparks from a welder working on a new Netflix building, the encoding team acquired a Sony PMW-F55 and the AXS-R5 RAW recorder to shoot 16-bit RAW SQ and produce Sparks.
Sparks was shot 4K HFR and finished at 4000 nits using ACES. Read more about Sparks on the Netflix Tech Blog.

Following the industry shift from “more pixels” to “better pixels,” we produced Meridian, our first test title to tell a story. Meridian was mastered in Dolby Vision high dynamic range (HDR) with a P3-D65 color space and PQ (perceptual quantizer) transfer function. It also contained a Dolby Atmos mix, multiple language tracks, and subtitles. You can read more about Meridian on Variety.

Cosmos Laundromat (2016)
We felt a need to include animated content in our test title library, so we partnered with the Open Movie Project and Fotokem’s Keep Me Posted to re-grade Cosmos Laundromat, an award-winning short film in Dolby Vision HDR.
This open source 3D animation was created by French artist Mathieu Auvray in Blender, an open source 3D tool.

Chimera is technically comparable to El Fuente, but its scenes are more representative of existing titles on Netflix. The dinner scene attempts to recreate a codec-challenging sequence from House of Cards.
Prior to Chimera, there wasn’t any open source 4K test material that exhibited real world live action material.

El Fuente (2013)
As the demand for more pixels increased, so did appropriate test content. Documentary short El Fuente was shot in Mexico by a local DP at 4K at both 48 and 59.94 fps to meet increasing resolution and frame rate requirements.
