Avid DNxHD Notes
The bit rates listed in the Codec Profile dropdown are the bit rates for 1080p at 29.97 fps EXCEPT for 36 fps (which is actually 45 Mbps @ 29.97fps). You should look at the codec format (422/444, 8/10-bit). Note: Hiero only supports 1080p and 720p. Non-HD resolutions are scaled to 1080p before writing. This leads to a set of 1080p bit rates: • 1080p/29.97 440x, 220x, 220, 145, 45 • 1080p/60 N/A, N/A, 440, 290, 90 (same at 59.94) • 1080p/50 N/A, N/A, 367, 242, 75 • 1080p/25 365x, 185x, 185, 120, 36 • 1080p/24 350x, 175x, 175, 115, 36 (same at 23.976) At 720p, the Codec Profile dropdown has a different interpretation. The bit rate is taken as the bit rate at 720p at 59.94fps. This leads to another set of bit rates: • 720p/59.94 N/A, 220x, 220, 145, N/A • 720p/50 N/A, 175x, 175, 115, N/A • 720p/29.97 N/A, 110x, 110, 75, N/A • 720p/25 N/A, 90x, 90, 60, N/A • 720p/23.976 N/A, 90x, 90, 60, N/A Note: Since the bit rates are for 1080p at 29.97 fps AND 720p at 59.94 fps (except for 36 Mbit which should read 45 Mbit). It is possible to calculate the bandwidth for all the other frame rates by: BandWidth@1080p = fps/29.97 * NominalBandWidth, or BandWidth@720p = fps/59094 * NominalBandWidth where NominalBandWidth is the bandwidth listed in the codec profile knob OR 45 if the bandwidth listed is 36 Mbit. (Avid labels the codec profile names by the approximate bandwidth.)
OpenEXR and OpenEXR 3.1.6 | 16, 32 | read and write | exr | OpenEXR handles 16- and 32-bit float. This 16 is also called "half float" and is different from the 16-bit integer that all the other formats that support 16-bit use. Hiero supports multi-part OpenEXR files. For more information, see the Hiero User Guide.
EXR Compression
EXR file metadata contains a compression key/value pair detailing the compression type used to write the .exr file. The value is expressed as the name of the compression type or an integer referencing the compression used: 0 - no compression 1 - RLE compression, run length encoding 2 - Zip compression, one scan line at a time 3 - Zip compression, in blocks of 16 scan lines 4 - PIZ-based wavelet compression, in blocks of 32 scan lines 5 - PXR24 compression, lossy 24-bit float 6 - B44 compression, lossy 4-by-4 pixel block, fixed rate 7 - B44A compression, lossy 4-by-4 pixel block, flat fields are compressed more 8 - DWAA compression, lossy DCT based compression, in blocks of 32 scan lines 9 - DWAB compression, lossy DCT based compression, in blocks of 256 scan lines

PSD | 8, 16 | read only | psd | While Hiero reads standard Photoshop® blend modes, it doesn't read Photoshop layer comps or recognize group blend modes. Photoshop layers are read into separate Hiero layers and anything that doesn't map into that is ignored.

RAW | n/a | read only | n/a | DSLR raw data files, such as Canon .CR2 files. These are only supported via the dcraw command line program, which you can download from the dcraw website. Bit depth and other specifications depend on the device. Some devices may not be supported.

XPM | 8 | read and write | xpm | This is the text-based format in which Hiero’s interface elements are stored.
YUV | 8 | read and write | yuv | This format does not specify resolution, so Hiero assumes a width of 720 pixels.
