• Top First: The video is interlaced and displayed as two separate interleaved fields.
The field containing the top line (even lines) is sampled at an earlier instant in time
than the field containing the bottom line (odd lines). This field order is commonly
used for high-definition video and standard-definition PAL video.
• Bottom First: The video is interlaced and displayed as two separate interleaved
fields. The field containing the bottom line (odd lines) is sampled at an earlier
instant in time than the field containing the top line (even lines). This field order is
commonly used for standard-definition NTSC video.
• Color space: Use this pop-up menu to convert the source media to a new color space,
including wide color gamut. Choose Automatic to allow Compressor to choose the best
color space based on the selected preset. You can also choose a manual setting to
override the default. For more information about wide color gamut, see Intro to wide
color gamut and HDR in Compressor.
• RAW to log: Use this pop-up menu to select how ProRes RAW conversion is done.
Choose Automatic to allow Compressor to choose the conversion method. You can
also choose a manual setting to override the default. This option is available only if the
source is ProRes RAW.
• Camera LUT: Use this pop-up menu to select the camera lookup table (LUT) applied
to the source. Select a custom LUT to transform your video from one color space to
another. This setting is enabled if the source is ProRes RAW and if “RAW to log” is
set to a value other than None. This setting is also enabled if “Camera log” in video
properties in the Job inspector is set to a value other than None.
• Codec: Choose one of two available transcoding formats, H.264 or HEVC.
• Encoder type: Use this pop-up menu to set the type of encoder. This pop-up menu is
enabled when Codec is set to HEVC. Choose from two options:
• Faster (standard quality): Encodes the output file using a faster codec, with standard
quality.
• Slower (higher quality): Encodes the output file using a slower codec, with higher
quality.
Important: Not all options are available on all hardware.
• Profile: Use this pop-up menu to set the quality of compression used in the output file.
When Codec is set to H.264, this pop-up menu offers three options:
• High: Provides high-quality output, which may not be compatible with older H.264
playback devices.
• Main: Similar to the Baseline profile, with additional support for standard-definition
(SD) video requirements.
• Baseline: Primarily for video conferencing and mobile applications.
When Codec is set to HEVC, the Profile pop-up menu sets the color depth of the output
file (the number of bits used to represent color in each color channel—red, green, and
blue). There are two options:
• 8-Bit Color: Provides a good balance between picture quality and file size. (This
option is available only on recent Mac computers that support hardware encoding
of HEVC.)
• 10-Bit Color: Provides better picture quality but with larger file sizes. (Because this
option uses software encoding, performance may be significantly slower than 8-bit
hardware encoding.)
