H.264 for Blu-ray/AVCHD preset in Compressor

Preset summary

The top section of the inspector displays the preset name and transcoding format, as well as an estimated output file size and a summary of video properties. When you add a preset to a job or change the preset’s properties, this summary is automatically updated.

General Properties

• Name: Displays the name of the preset.

• Description: Displays the description of the preset.

• Extension: Displays the extension of the output file (.264).

• Allow export segmentation: This checkbox is dimmed because job segmenting is not available for this preset.

• Default location: Choose an item from the pop-up menu to set the default save location for transcoded files.

• Stream usage: Use the pop-up menu to set whether the output file is transcoded for Blu-ray Disc or AVCHD.

Retiming

Sets the processing algorithm used to adjust the frame rate during transcoding. Select one of the following options:

• Set to percent of source using: Modifies the output clip’s speed by a percentage of the source clip’s speed. Enter a value in the percentage field or choose a preset value from the adjacent pop-up menu (with a down arrow).

• Set to: Sets the duration of the clip. Enter a timecode duration in the field or click the arrows to increase or decrease the time.

• Set so source frames play at [frame rate] fps: Nondestructively changes the playback speed of the clip without discarding frames or creating new frames. This property has no effect unless the “Frame rate” value in the Video inspector is different from the source file’s frame rate. For example, if you add a 10-second source file with a frame rate of 24 fps to Compressor, set the “Frame rate” property in the Video inspector to 25 fps, and then select “Set so source frames play at 25 fps” in the General inspector, the resulting duration of the transcoded clip (at 25 fps) will be 9 seconds and 15 frames.

For more information, see Retime video and audio using Compressor.

Video Properties

• Frame size: Use the pop-up menu to set the frame size (resolution) for the output file. See Intro to modifying frame size in Compressor.

• Center crop for output aspect ratio: Select this checkbox to ensure that when changing the aspect ratio in the Frame size pop-up menu, the video remains centered in the new aspect ratio.

• Pixel aspect ratio: For presets that use the H.264 format, the pixel aspect ratio is automatically set to Square.

• Frame rate: Use this pop-up menu to set the playback rate (the number of images displayed per second) of the output file. See Retiming options in Compressor.

• Field order: For presets that use the H.264 format, the field order is automatically set to Progressive (in which complete frames are scanned).

• Color space: Use this pop-up menu to convert the source media to a new color space. The default preset is Automatic, which allows Compressor to choose the best color space based on the selected preset. You can also choose a manual preset to override the default.

• 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 preset 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 preset is enabled if the source is ProRes RAW and if “RAW to log” is set to a value other than None. This preset is also enabled if “Camera log” in video properties in the Job inspector is set to a value other than None.

• Stereoscopic: Use this pop-up menu—available for stereoscopic files or when you create a new stereoscopic preset—to choose how Compressor uses the left and right eye views in stereoscopic video:

  • Automatic: Automatically chooses a frame-packed or monoscopic output setting based on the source media. For monoscopic output, Compressor uses the hero eye if it can be determined from the file’s metadata; otherwise, the left eye is chosen.

  • Left Eye Monoscopic: Uses the left eye of the stereoscopic source to output a monoscopic video.

  • Right Eye Monoscopic: Uses the right eye of the stereoscopic source to output a monoscopic video.

• Cinematic: Use this pop-up menu—available for video recorded in Cinematic mode with the iPhone Camera app—to specify how to handle Cinematic metadata (requires macOS 12 or later). There are two options:

  • Ignore: The Cinematic mode effect is not rendered in the output.

  • Render: The Cinematic mode effect is rendered in the output.

  Note: This menu is only visible if the video file you imported has Cinematic mode metadata. You may need to adjust certain settings to ensure the metadata is retained when you import the file. For more information, see the Motion User Guide.

• Automatically select bit-rate: Select this checkbox to have Compressor automatically compute the best bit rate for the output file, based on the duration of the source file. If the checkbox is not selected, you can set the average and maximum bit rates by dragging the “Average bit rate” and “Maximum bit rate” sliders or entering values in the text fields.

• Multi-pass: Select this checkbox to turn on multi-pass encoding, which applies an analysis of video frames to produce a high-quality output file. For faster (single-pass) transcoding, deselect the checkbox.

  Note: Multi-pass encoding is not available on all hardware or with all preset configurations.

Cropping, Padding, and Rotation

Customize the final cropping, sizing, aspect ratio, and orientation of video in Compressor using the Cropping, Padding, Rotation, and Flip properties.

Cropping removes video content from an image. Padding scales the image to a smaller size while retaining the output image’s frame size. For more information about these properties, see Intro to modifying frame size in Compressor.

You can also rotate and flip the final output image in Compressor using the Rotation and Flip properties. These allow you to rotate a widescreen image to be vertical, or to reverse the image horizontally, vertically, or both.

• Cropping: Use this pop-up menu to set the dimensions of the output image. The default setting is None, but you can choose a cropping preset in the menu to change the dimensions of the output image. Choose Letterbox Area of Source to have Compressor detect image edges and automatically apply crop values. This is useful if you want to remove a source file’s letterbox area by cropping out the black bars above and below the widescreen image. Choose “Center crop for output ratio” to ensure that the video remains centered in the new aspect ratio when you modify the frame size of the output. For custom cropping, choose None, then enter pixel values into the Top, Bottom, Left, and Right text fields below.

• Padding: Use this pop-up menu to set the scaling of the output image while retaining the size of the frame. This is particularly useful when you’re creating a pillarbox (black bars on the sides of the frame) or a letterbox (bars above and below the frame) around your source material. The default padding is Preserve Source Aspect Ratio, which ensures that the aspect ratio remains unchanged as you modify the frame size of the output. You can select one of the predetermined presets in the menu to add a standard padding preset, or you can enter custom pixel values into the Top, Bottom, Left, and Right text fields below the menu to create your own custom padding.

• Rotation: Use this pop-up menu to set the rotation of the output image. The default rotation is None, but you can choose to rotate your image 90 degrees, 180 degrees, or 270 degrees. This is useful in situations when a camera was oriented incorrectly when capturing the video.

• Flip: Use this pop-up menu to flip the output image. The default setting is None, but you can choose Horizontal, Vertical, or Horizontal and Vertical. This is useful if you want the output image to mirror the input image horizontally, vertically, or both.

  Note: The Rotation property is always applied before the Flip property.

Quality

The following properties set the processing algorithm used by Compressor during the transcoding process. For more information about using these controls, see Retime video and audio using Compressor and Modify timing and frame rate in Compressor.

• Resize filter: This pop-up menu sets the resizing method. There are several options:

  • Nearest Pixel (Fastest): Samples the nearest neighboring pixel when resizing an image. This option provides the fastest processing time, but it’s more likely to show aliasing artifacts and jagged edges.

  • Linear: Adjacent pixel values are averaged using a linear distribution of weights. Produces fewer aliasing artifacts than Nearest Pixel, with a small increase in processing time.

  • Gaussian: Adjacent pixel values are averaged using a Gaussian distribution of weights. This provides a medium trade-off between processing time and output quality.

  • Lanczos 2: Adjacent pixel values are averaged using a truncated sinc function. This option is slower than Gaussian but provides sharper results.

  • Lanczos 3: Similar to Lanczos 2 but averages more pixel values. This option is slower than Lanczos 2 but may produce better results.

  • Bicubic: Adjacent pixel values are averaged using a bicubic function. The processing time and output are most similar to Lanczos 2 and Lanczos 3.

  • Anti-aliased (Best): Provides the highest output quality, but can take substantially longer to process.

• Retiming quality: This pop-up menu sets the retiming method. There are four options:

  • Fast (Nearest Frame): Linearly interpolates frames using nearest neighbor frames.

  • Good (Frame Blending): Blends neighboring frames using a filter to produce good-quality interpolation.

  • Best (Motion Compensated): Uses optical flow to interpolate using areas of movement between neighboring frames to produce high-quality output.

  • Reverse Telecine: Removes the extra fields added during the telecine process to convert the film’s 24 fps to NTSC’s 29.97 fps. See Use reverse telecine in Compressor.

• Adaptive details: Select this checkbox to use advanced image analysis to distinguish between noise and edge areas during output.

• Anti-aliasing level: Sets the softness level in the output image. Double-click the value and then manually enter a new value or drag the slider to the right to increase softness. This property improves the quality of conversions when you’re scaling media up. For example, when transcoding SD video to HD, anti-aliasing smooths jagged edges that might appear in the image.

• Details level: Sets the amount of detail in the output image. Double-click the value and then manually enter a new value or drag the slider to set the value. This sharpening control lets you add detail back to an image being enlarged. Unlike other sharpening operations, the “Details level” property distinguishes between noise and feature details, and generally doesn’t increase unwanted grain. Increasing this value may introduce jagged edges, however, which can be eliminated by increasing the “Anti-aliasing level” slider.

• Dithering: When selected, adds a certain type of noise to images to prevent large-scale distracting patterns such as color banding. If your image has excessive noise after rendering, deselect this checkbox.
