AVX Plug-Ins
If your project contains AVX
™
plug-in effects and you are moving across platforms, make sure
the same plug-ins are available on both the Macintosh and Windows systems. If the same AVX
plug-in effect is not available, you can mix down or render the effect to a high-quality resolution
and then transfer it using an OMFI or an AAF file. However, you cannot change the parameters
of the effect.
Preparing Graphics for the Online Session
The most critical step when preparing graphics for online is to make sure that the elements you
are going to import are created correctly. The following table summarizes various requirements.
Aspect Requirement Notes
Frame size
(4:3)
Square pixels:
648 x 486 (NTSC)
640 x 480 (NTSC DV)
768 x 576 (PAL)
These are the preferred sizes for NTSC and PAL. You can also use
720 x 540, in some situations, for both NTSC and PAL. These are
stored by your Avid editing application as non-square pixels.
Frame size
(16:9)
Square pixels:
864 x 486 (NTSC
anamorphic)
1024 x 576 (PAL
anamorphic)
1280 x 720 (HD)
1920 x 1080 (HD)
Preferred sizes. SD media is stored by your Avid editing application
as non-square pixels.
Alpha channel White foreground
(transparent), black
background (opaque)
This is the standard used by graphics, animation, and compositing
packages. You need to invert the alpha channel of graphics on
import.
Color mode RGB
ITU-R 601
ITU-R 709
Other formats, including CMYK, might cause import errors.
ITU-R 601 is used for SD and ITU-R 709 is used for HD. In HD
projects, your Avid editing application automatically converts the
media.
File format Various Your Avid editing application accepts many file formats for input.
TIFF (.tif) and PICT (.pct) are commonly used formats. See “Import
Specifications for Supported Graphics File Formats” on page 1451.
