All of the rendered frames in 4k, as 16 bits TIFF files, are now available here:

You can also find the HD scaled down png files there for encoding fun!

It is awesome these are available. I’m spending my 4th of July playing around with making some UHD and HDR encodes from them.
However re-graded TIFF files aren’t tagged with a color space, which would be useful in trying to generate HDR content from the sequence. Are they just the standard sRGB IEC61966-2.1? That is what the re-graded 1080p PNG files are set to.
Also, they don’t appear to have even LZW compression applied; exporting graded_edit_00893.tif to LZW TIFF via Photoshop yielded a reduction from 125 MB to just 45 MB. Apply that basic compression could save Xiph.org a *LOT* of bandwidth!
Hi Ben,
It’s all standard sRGB.
The TIFFs were saved using Blender, I should inspect if this has compression even… will do next time :)
Hi Guys,
do you know any commandline tool(or just any tool) to convert TIF images into YUV video file?
FFMPEG can convert a TIF image sequence to YUV.
The command syntax would be something like…
ffmpeg -i c:\Tears4K\graded_edit_%05d.tif -pix_fmt yuv420p Tears4K.YUV
