The Letterbox Area of Source option detects image edges and automatically enters crop values to match them. This is useful if you want to crop out the letterbox area the black bars above and below a widescreen image of a source media file. The custom option allows you to enter your own scaling dimensions in the fields; other options use predetermined dimensions. The following properties determine how Compressor resizes, retimes, and otherwise adjusts the video when transcoded:.

Nearest Pixel Fastest : Samples the nearest neighboring pixel when resizing an image. This option provides the fastest processing time, but it is 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. 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. Choosing this item disables all the other Quality controls.

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. 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. 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. For a list of available video effects in Compressor, and instructions on how to add a video effect to a setting, see Add and remove effects in Compressor.

Enable audio pass-through: Select this checkbox to copy the source audio unmodified to the destination file. When this checkbox is selected, all the other settings in the Audio Properties area are disabled. Channel layout: Use the pop-up menu to set the audio channel layout. See Audio channel layouts in Compressor. Sample rate: Use this pop-up menu to set the number of times per second that music waveforms samples are captured digitally.

The higher the sample rate, the higher the audio quality and the larger the file size. Sample size: Use the pop-up menu to manually set the sample size of the audio signal. To manually change the codec used in your setting, use this pop-up menu. Bit rate: If you have selected AAC as an audio codec, use this pop-up menu to set the bit rate for the encoded audio.

Converting amongst file formats is simple in procedure but may require some detailed knowledge of the formats involved to obtain good results.

Reply I have this question too 34 I have this question too Me too 34 Me too. Answer: A: Answer: A: I'm just wondering when you say Do you mean press the Command key and capital I key at the same time or the command key and 1? Am referring to the system's "Finder Information" feature here.

Sorry, I tend to assume everyone is familiar with this Finder feature since I use it so often to check dates, compare files sizes, check the formats of media files that will not open in the QT Player, create custom Finder icons, etc. View answer in context.
