Output Settings area Format: Specifies the exporter, which broadly determines the type of output. DirectShow: AVI container QuickTime: MOV container Frame Sequence: A series of individual still image files, one per frame, rather than a single video clip. Codec: Specifies the encoder used to encode and compress the output file. The options that are available in this list depend on the format that's selected. If you select DirectShow AVI, then the list of codecs depends on what's installed on the computer independently of Ultra. Configure: Opens the configuration panel for the selected codec. This button is disabled for codecs that do not have any configuration options available. 24-bit / 32-bit Keyed Source: These options are available if you set the format and codec to QuickTime and Apple None or one of the other file formats that supports an alpha channel. 24-bit: Creates an output file with no alpha channel. 32-bit Keyed Source: Creates an output file with an alpha channel for use in another compositing application. The extra 8 bits per pixel is for the transparency information. Invert Alpha: This option is available if you select 32-bit Keyed Source. When enabled, Ultra reverses how it encodes the alpha channel data. This is for compatibility with applications that interpret the alpha channel as film alpha, in which a value of 0 indicates complete opacity. Type 1 and Type 2: These options are available if you set the format to DirectShow and set the codec to DV Video Encoder. Type 1 DV: Saves a single stream containing both the video and audio. Type 2 DV: The output consists of two streams: one stream for the audio and one stream for the video. This format is compatible with more applications than the Type 1 DV format. Resolution: Specifies the dimensions of the frame for the output movie, in pixels. You cannot change the resolution for some codecs. Frame Rate: Specifies the frame rate, in frames per second (fps), for the output movie. Field Order: Specifies whether the output movie is progressive or interlaced. If the output movie is interlaced, this setting specifies which field is first. Flicker Filter: If the output video has sharp lines of contrast and will be viewed on a television, reduces flickering or strobing along those lines. File Information area Folder: Displays the path where the output movie is saved. 46 Product overview
