Frame Size for Imported Graphics

The table in this topic shows the frame sizes to use when creating and importing graphics and

sequences. The table includes sizes for both square and non-square pixels.

Computer displays, most graphic and animation programs, and most HD video formats use

square pixels. Standard-definition (SD) digital video does not use square pixels. The ITU-R 601

standard specifies a 720-pixel width for both NTSC and PAL. However, because NTSC and PAL

each has a different number of scan lines (486 for NTSC, 576 for PAL), digital video pixels are

stretched vertically for NTSC and horizontally for PAL. These stretched pixels are referred to as

non-square pixels.

Your Avid editing application stores SD video and DVCPRO HD video as non-square pixels and

stores other HD video as square pixels.

Some graphics programs can render a graphic or animation in either square or non-square pixels.

In general, you should render standard-definition animations and composites in non-square

pixels, but export static graphics in square pixels (your Avid editing application converts these

into non-square pixels during the import process).

The numbers in the following table describe the recommended width and height, in pixels, to

create a source image that displays full-screen after import. An image with smaller dimensions

takes up less of the screen or is distorted, while an image that exceeds these dimensions might

appear distorted, depending on your choices when importing. For more information, see “Import

Settings: Image Tab” on page 1414.
