Avid|DS 5.0 Release Notes • November 2001 12
Capture from File with Preserve Alpha Option Always Results in Filled Alpha
The media conversion modes in the Media Input/Output layout allows an image to be scaled during conversion.
If the resulting scaled image is smaller than the current sequence resolution (usually with modes supporting "keep
original size"), the difference is filled with black pixels. In this situation, when the Preserve Alpha option is selected,
you expect that the alpha would only cover the image and the black pixels would be considered transparent.
However, Avid|DS 5.0 marks the whole image as being covered by alpha, not just the non-transparent black portions
of the image. To work around this, link the image instead of capturing it and alpha will be correctly handled.
Paint and Titling
Import Limitations
§ You can import a subset of the Adobe Illustrator EPS format. Only the shape and color information is imported.
§ You can import HTML text and basic formatting information, such as font style, color, and tabulations (as
HTML tables). This does not, however, include other HTML tags, such as images, forms, or scripts. Recent
versions of word processing software, which add XML markup tags along with HTML, are not supported.
We recommend that you use earlier versions as XML is not yet supported.
Raster Paint Limitations
§ The .gen files generated when burning frames are managed on a per project basis, so deleting or not saving
sequences that contain burned frames may leave orphaned .gen files. To help track and delete these files, enter
a name in the Base Cache File Name text box in the Graphics property page, use the rastered frames tooltips in
the Graphic Object View (GOV), or use the Save option when right-clicking on the rastered frames in the GOV.
Deleting a project will also destroy all associated burned frames.
§ Presets of graphics sessions that contain burned frames cannot be reloaded in sequences that have a different
resolution or frame rate.
§ The burned frames of graphics sessions become opaque. Changes to any effect underneath a graphics session
will be ignored for those frames.
§ Burned frames are not visible when a paint sequence is used as a proxy (Alt-drop from browser). To work
around this, select the Non-real-time option and process.
Artifacts in Interactive Display of Effects
The interactive display of the following effects contain very noticeable artifacts:
§ Brushes: Bas Relief, Chrome, Glass, and Textured.
§ Keyer: HLS Keyer with the Fast Blur option selected.
These artifacts appear only during interactive display, not when the frames are processed. To work around this, exit
the graphics session, make sure the play cursor is not over the graphics session, purge memory caches, and process.
Display Quality May Decrease if Viewer Resized to Less Than D1 Resolution
If you resize the viewer to less than D1 resolution, the image in the viewer will also resize. This may decrease the
image quality. The viewer is resized if you edit the default layout and make the viewer smaller than D1, or if you
work in Non-square Pixels mode. In both cases, an exclamation point (!) is displayed at the bottom-right of the
viewer to indicate that you are not viewing the image at D1 quality.
