Working with Filters

You can treat your source media file with a variety of filters before you transcode it to help improve the output quality of your video and audio. The best way to assign these filter settings is to look at, and listen to, your source media file and choose the most suitable one based on its content.

Previewing Filters

You can preview a clip containing your current filter settings by clicking the target in the Batch window to open it in the Preview window. The Preview screen is split into original and transcoded versions of your media file so that you can see or hear the effects of your filter settings before processing the batch (as long as the checkbox for that particular filter is selected).

This can be helpful when you are applying multiple filters since it can be difficult to anticipate how the filters will interact with each other.

Important: The order of the filters in the filter list defines the order in which they are applied to the video or audio. Try changing the order of the filters if you are seeing unexpected results in the Preview window.

Once you are reasonably happy with your settings, it’s a good idea to scan through the whole movie to ensure that your changes are not too extreme for some scenes.

Note: Depending on your system, the source media file type, and the number of filters applied, the Preview window showing the filter settings may update at a lower frame rate than the source frame rate.

See Using the Preview Window for more information.

Color Spaces

Compressor supports the following color spaces: YUV (R408), 2VUY, RGBA, ARGB, and YUV (v210). Some filters require a color space conversion and some filters can handle various color spaces. For each media file, Compressor chooses the most suitable color space to provide the best output and performance results based on the color space of three attributes: the source media format, the output file format, and chosen filters. Optionally, you can use the Output Color Space pop-up menu (in the Color tab) to manually adjust the color space for the output media file.

For more information about how you can adjust color spaces, see Color Tab.
