Adds support for Apple ProRes 4444 and Apple ProRes 422 on Mac, Linux, and Windows using the mov64 reader.

Apple ProRes 4444 includes the SD, HD, 2K, UHD, and XQ formats. Apple ProRes 422 includes the HQ, LT, and Proxy formats.

AVI files can be supported by default or via Hiero’s reader/writer that is based on the FFmpeg open source library. If you get an error when using AVI files in Read nodes, you may need to use the prefix mov64: before the file path and file name, for example:

mov64:z:/job/FILM/IMG/final_comp_v01.####.avi

When working with Write nodes, you can also select mov64 from the file type dropdown menu and use avi as the file extension.

On Windows, in order to support more codecs, the AVI reader uses the DirectShow multimedia architecture. When decoding .avi files, DirectShow tries to find the appropriate codec on the system. If the codec is not available, DirectShow and Hiero are unable to open the .avi file. Note that the 64-bit version of Hiero can only use 64-bit DirectShow codecs. If you only have a 32-bit codec installed, the 64-bit version of Hiero cannot use it to open .avi files.

Includes RAW 2.5K CinemaDNG

YCbCr encoded DPX files are not supported on the timeline.

This format stores an 8-bit mantissa for each of r, g, and b and an additional 8-bit exponent that is shared by all three, which packs the floating point RGB triplet into 32 bits per pixel.

Adjust compression levels using the quality slider in the Write node’s properties panel.

Note:  Currently, only 'complete' MXF files are supported.

Supported codecs include:

• Uncompressed 4:2:2 YCbCr 8-/10-bit

• Uncompressed 4:4:4:4 RGBA 8-/10-bit

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 Nuke User Guide.

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

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.

QuickTime is only supported by default on Windows and Mac. To use QuickTime files on Linux, you need to use the prefix mov64: before the file path and file name, for example,
mov64:/z:/job/FILM/IMG/final_comp_v01.####.mov

The mov64 writer supports the following codecs:

• Apple ProRes 4444

• Apple ProRes 4444 XQ

• Apple ProRes 422 HQ

• Apple ProRes 422

• Apple ProRes 422 LT

• Apple ProRes 422 Proxy

• Avid DNxHD (1080p and 720p 1920x1080 and 1280x720, 4:4:4:4 and 4:2:2) 36, 115, 120, 145, 175, 185, 220, 220x

Note:  Interlaced writing is not supported. See Avid DNxHD Notes for more information.

• Photo - JPEG

• MPEG-1 Video

• MPEG-4 Video

• PNG

• Animation

• Uncompressed 10-bit 4:2:2

The bit rates listed in the codec profile dropdown are the bit rates for 1080p at 29.97 fps EXCEPT for 36 (which is actually 45 Mbps @ 29.97fps). You should look at the codec format (422/444, 8/10-bit).

Note:  Nuke 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

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.

Note that .r3d files may look different in Hiero compared to various versions of RED applications, like RED ALERT or REDCINE. Unlike most other file formats Hiero reads, the .r3d REDCODE files must be processed to convert from a raw format to an RGB color image. From time to time, a new version of the RED SDK that Hiero uses improves this processing and due to the timing of release cycles, Hiero may sometimes be using a different version than the RED applications.

If utilized, the compression schema on imported TIFF sequences must be LZW®.

This is the text-based format in which Hiero’s interface elements are stored.
