Transcoding is the process by which Encore converts your original, non-DVD-compliant or non-Blu-ray Disc-compliant video and audio asset files to the compliant elements that are burned to the disc. (Files that are already compliant do not require transcoding.) The transcoding feature of Encore is flexible enough for a variety of users. New users unfamiliar with transcoding can let the application manage the process entirely, while those with more experience can control it precisely. If you choose to manage transcoding yourself, Encore provides DVD-compliant and Blu-ray Disc-compliant transcode presets customized for several different quality and storage requirements. You can also create your own custom transcode presets.
You can work with your original, untranscoded files throughout the production process; Encore performs any required transcoding when you build the final project. If you want more control over transcoding, however, you can choose to transcode at any time on a per-item basis. If a transcoded version of a file is available, Encore uses that version for authoring, previewing, and building; if no transcoded version is available, the application uses the original file for authoring and previewing, and transcodes the files as necessary when building.
You can specify an item’s transcode settings (by using a preset) from the DVD Transcode Settings or Blu-ray Transcode Settings columns in the Project panel. (Separate columns, DVD Transcode Status, and Blu-ray Transcode Status, display either Transcoded or Untranscoded to show the item’s current state.) When you specify a preset, that preset’s data rate is used, not the data rate you calculated in bit budgeting.
Assets are designated as follows in the DVD Transcode Settings and Blu-ray Transcode Settings columns:
- Displayed for all non-DVD-compliant or non-Blu-ray Disc-compliant assets
by default. For assets with the Automatic designation, Encore determines the optimal settings for transcoding. Encore bases these settings on the number, length, and size of the assets and the available disc space. (See About bit budgeting.) You can override the Automatic data rate setting by specifying the Maximum Audio/Video Bitrate on the Advanced tab of the Project Settings dialog box. Alternatively, you can specify a transcode preset for any of these assets.Important: Set the encoding profile as Main for your H.264 video assets in your Blu-ray projects. You cannot burn a Blu-ray Disc if you set the encoding profile as High. See Preset options for video
- [A transcode preset name]
- Displayed for all non-DVD-compliant or non-Blu-ray Disc-compliant assets for which you have specified a Project Transcode Preset.
- Don’t Transcode
- Displayed for those assets that are already DVD-compliant
or Blu-ray Disc-compliant. You can override this setting and specify
Automatic or a transcode preset, if desired.Note: DVD/Blu-ray Disc-compliant, audio-only files that don’t match the audio encoding preference are the exception; Encore assigns these audio files a designation of Automatic. You can override this setting and specify either Don’t Transcode or a transcode preset. (Dolby® Digital 5.1 AC3 files retain the Don’t Transcode designation for quality purposes; this designation can also be overridden to transcode to Dolby® Stereo format.)
- Displayed for those items, such as menus and timelines, that don’t require transcoding.
Transcode assets from the Project panel
You can assign transcode settings and transcode individual assets directly from the Project panel. Upon transcoding a file, Encore updates the project link so that it points to the transcoded file. Consequently, unless you delete the original file, you can revert transcoded assets to their original version. Encore transcodes in the background, so you can continue to work while transcoding.
The data rate calculated for the Automatic transcode setting, determined by Encore, appears in the Bitrate column in the Project panel. You can specify the maximum automatic data rate using the Advanced tab in the Project Settings dialog box.
Assign a transcode setting to an asset
In the Project panel, right-click (Windows) or Control-click (Mac OS) the asset you want to transcode, and choose Transcode Settings.
In the Transcode Settings dialog box, choose a transcode preset from one of the Quality Preset menus for DVD Transcoding or Blu-ray Transcoding, and then click OK. (For information on editing the presets, see About project transcode presets.)
Override the Automatic data rate setting
To specify the maximum audio/video transcoding bit rate that Encore uses automatically, choose File > Project Settings, click the Advanced tab, choose the data rate limit from the Maximum Audio/Video Bitrate menu, and then click OK.
Transcode an asset
In the Project panel, right-click (Windows) or Control-click (Mac OS) the asset you want to transcode.
Choose Transcode Now. The asset is transcoded, and the Transcode Status column displays Transcoded. The transcoded asset is now used for authoring, previewing, and building.
Out of process transcoding enables you to transcode assets in the Adobe Media Encoder application in the Transcode Now workflow. When you enable out-of-process transcoding, the Adobe Media Encoder (AME) is launched as a separate process.
Out-of-process transcoding runs independent of the Encore process. The memory in the Encore process is not consumed when transcoding.
