You may also manually change the settings and save them as a custom template for future use. To create a new template, enter a name in the text box and click the Save Template button . The new custom template name is added to the drop-down list.

To set your project properties to match the properties of an existing media file, click the Match Media Settings button and browse to the file you want to use.

The maximum frame size is 4096×4096.

• None (progressive scan): Select this option when viewing the video on a computer. This option ignores interlacing.
• Upper field first: Select this option (also called odd or field A) for video that will be viewed on a television.
• Lower field first: Select this option (also called even or field B) for DV output or if Upper field first produces jittery or shaky output.

Computers display pixels as squares, or a ratio of 1.0. Televisions display pixels as rectangles (ratios other than 1.0).

Using the incorrect setting can result in distortion or stretching. Consult your capture/video output card’s manual for the proper settings.

In this example, the video was shot with the camera tripod rotated 90 degrees. However, with the project output unrotated, the video is pillarboxed within the standard landscape frame.

After choosing 90 clockwise° from the Output rotation drop-down list, the Video Preview window is rotated, and the video fills the frame.

If you want to rotate a media file’s orientation, you can use the Rotation drop-down list on the Media Properties dialog.

For more information, see “Creating rotated projects.”

The television frame rate in the US, North and Central America, parts of South America, and Japan (NTSC) is 29.97 frames per second (fps). In many parts of the world, including Europe and much of Asia, the television standard is PAL at 25 fps. France, Russia, and most of Eastern Europe use SECAM, which is a variation on PAL and also uses 25 fps.

By default, the project’s Stereoscopic 3D mode, Swap Left/Right, and crosstalk cancellation settings will also be used when previewing and rendering your project, but you can override the project settings if necessary.

For more information, see “Setting up your stereoscopic 3D project.”

• 8-bit: Performs video processing using 8-bit arithmetic and in the video (studio RGB, or 16-235) color space.
• 32-bit floating point (video levels): Performs video processing using 32-bit arithmetic and in the video color space.
• 32-bit floating point (full range): Performs video processing using 32-bit arithmetic and in the full-range color space.The 32-bit floating point settings allow greater precision for processing video, but require significantly more processing power than working with 8-bit video.

Tips:

• 32-bit floating point (video levels) is recommended when working with 10-bit YUV input/output or when using xvYCC/x.v.Color media.
• When using 8-bit input/output, the 32-bit floating point (video levels) setting can prevent banding from compositing that contains fades, feathered edges, or gradients.
• Video plug-ins and media generators that support floating-point processing are included in the 32-bit floating point folder in the Transitions, Video FX, Media Generators, Compositors, and Plug-In Manager windows.
• If you’re creating a 32-bit project, you can increase performance during editing and playback by using the 8-bit setting during editing and switching to 32-bit floating point (video levels) before rendering.

• 1.000 (Linear): The default setting when you choose 32-bit floating point (full range) from the Pixel format drop-down list.
• 2.222 (Video): Processing in 8-bit video is always performed using a setting of 2.222.

Unless you have specific performance problems, choose Good. Choosing Best can dramatically increase rendering times.

Good uses bilinear scaling without integration, while Best uses bicubic scaling with integration. If you’re using high-resolution stills (or video) that will be scaled down to the final output size, choosing Best can prevent artifacts.

Some file formats allow you to associate a video rendering quality setting with a custom rendering template. Final rendering template settings override the Full-resolution rendering quality setting in the Project Properties dialog. For more information, see “Custom rendering templates.”

Motion blurring creates the illusion of motion on individual frames (much like using a long exposure time) and can make computer-generated animation appear more smooth and natural.

• Gaussian: Gives more weight to the central frame in the blur and less weight to the outer frames. A bell-shaped curve is used between the central and outer frames. Gaussian blur is the best choice in most situations where blurring is required.
• Pyramid: Gives more weight to the central frame in the blur and the least weight to the outer frames. A linear slope is used between the central and outer frames.
• Box: Uses an equal weighting for all frames, essentially averaging the frames in the blur.

The Gaussian (asymmetric), Pyramid (asymmetric), and Box (asymmetric) settings use only the left half of each curve, from the central frame back. Asymmetric settings create a hard leading edge with a trailing blur behind the moving object.

• None: Performs no deinterlacing.
• Blend fields: Uses contents from both fields and works well for high-detail, low-motion video.
• Interpolate: Uses a single field at a time and works well for high-motion, low-detail video.

No deinterlacing occurs in the Draft and Preview video preview modes. The Good and Best modes apply the selected deinterlacing method.

This setting will correct for the following types of inconsistencies:

• DV media will be cropped for 320×240 Internet renders to prevent letterboxing.
• DV widescreen media will be cropped in HD projects.
• HD media will be cropped in DV widescreen projects.
• 486-line media will be cropped in 480-line projects.
• 480-line media will be padded in 486-line projects.

When the check box is cleared, source media files are processed with their native settings.

If you want to change the location of the folder, click the Browse button and choose a location. Ideally, this location should be on a different hard drive than the one where your operating system is installed.

Prerendered files can consume significant drive space. Select a folder on an a/v-capable drive with ample free space: DV requires approximately 228 MB per minute.
