Long-GOP Splicing for HDV Encoding
Your Avid editing application uses a technique called long-GOP splicing when encoding an
HDV MPEG-2 sequence for export. Your Avid editing application uses splicing to reconstruct
only the edited sections of the media, such as cut points, transitions, and segments that contain
effects. Other areas of the sequence are copied intact. The result is faster encoding at higher
quality.
Outputting HDV through Avid Input/Output Hardware
You can use Avid input/output hardware to output a sequence created with HDV media, but you
must transcode the sequence and then use the standard Digital Cut tool.
To perform a digital cut on a system using Avid input/output hardware:
1. Select the sequence or marked section.
2. Transcode the sequence as described in “Outputting HDV” on page 1529.
3. Select Output > Digital Cut
4. Proceed as with any digital cut.
See “Using the Digital Cut Tool” on page 1063.
Exporting an HDV Transport Stream
You can export an HDV transport stream for use in other applications.
