Transcoded AVC-Intra Editing Workflow

When you ingest the AVC-Intra files for this workflow, you transcode the files to an Apple ProRes codec (or to DVCPRO HD). For the best-quality footage, use the Apple ProRes 422 (HQ) codec. However, if you’re doing an offline edit or producing an EDL, and footage quality for editing is not an issue, you can save disk space and bandwidth by editing with Apple ProRes 422 (LT) files or even Apple ProRes 422 (Proxy) files.

Figure. Diagram showing the four stages of the transcoding workflow: shooting, ingesting, editing (in an alternative format), and finishing.

The transcoded footage results in self-contained QuickTime movies that you can edit in the Final Cut Pro Timeline.

Before ingesting the AVC-Intra files, you must specify an Apple ProRes codec as the destination codec in the Log and Transfer window preferences. For more information, see Stage 2: Choosing an Apple ProRes Codec for Transcoding.

The transcoded AVC-Intra workflow follows the standard steps of ingesting file-based media using the Log and Transfer window.

Stage 1: Choosing an Apple ProRes Codec for Transcoding

Decoding native AVC-Intra footage for playback requires a lot of processing power. To reduce the processing demands on your computer, you can use the Log and Transfer window to transcode your AVC-Intra footage to the less processor-intensive Apple ProRes format. Your sequence settings then change to the default Apple ProRes settings appropriate to the ingested footage.

To choose the destination codec for transcoded AVC-Intra footage
  1. Mount the volumes that contain your AVC-Intra media.

  2. Open the Log and Transfer window, then choose Preferences from the Action pop-up menu (with a gear icon) in the upper-right corner of the Browse area.

  3. In the Import Preferences dialog, select P2 AVC-Intra in the Source Format column.

  4. Choose an Apple ProRes codec or choose DVCPRO HD from the pop-up menu in the Target Format column corresponding to the P2 AVC-Intra item in the list, then click OK.

    The recommended codec for high-quality media transcoded from AVC-Intra footage is Apple ProRes 422 (HQ).

Stage 2: Transcoding Your AVC-Intra Footage

You transfer AVC-Intra footage to your scratch disk using the Log and Transfer window in Final Cut Pro. In this workflow, the AVC-Intra footage is transcoded as it is transferred. For more information about using the Log and Transfer window, see “Overview of Transferring File-Based Media” and “About the Log and Transfer Window” in the Final Cut Pro 7 User Manual.

Important: Although it is possible to copy AVC-Intra files directly to your scratch disk, Final Cut Pro won’t recognize these files. You must use the Log and Transfer window to transfer and transcode AVC-Intra footage.

Stage 3: Editing Video Using Transcoded AVC-Intra Footage

Editing video transcoded to an Apple ProRes codec is the same as editing other formats in Final Cut Pro. However, you need to make sure your scratch disk supports the data rate.

For more information about the data rates of the Apple ProRes codecs, see Working with Apple ProRes.

After you have completed your edit in Final Cut Pro, you have a range of finishing and output options for your AVC-Intra project. For more information, see Finishing and Outputting AVC-Intra Projects.
