Avid|DS 4.02 Release Notes • June 2001 7
Compositing and Effects
Incorrect Results/Errors with Depth of Field and 3D Fog Effects
Since the depth information is not timewarped, incorrect results are produced if you apply the Depth of Field or
3D Fog effect to a timewarped clip.
There must be a one-to-one mapping between depth files and frames in the clip. When a single rendered frame
is trimmed out in Avid|DS, the number of frames increase but a single .Zpic file remains, causing an error
message to appear. If you want to use a single frame image with the Depth of Field or 3D Fog effects, copy the
file as many times as you want it to be displayed, and number each file. For example: MyClip.1.pic,
MyClip.2.pic, etc.
Undo Limitations
If you change any parameter settings in the 3D Warp effect, you cannot undo the changes.
If you change a parameter after processing a tracked shot, undoing the action or entering the original value will
not recover the cache as it does for other effects or transitions. You must reprocess the effect.
Properties changed using the interactive tools of AVX plug-ins cannot be undone with the Ctrl+Z
keyboard shortcut.
Bypass Limitations
When two or more property editors are open in the Compositing layout, bypass may not work if it’s selected on
multiple property editors. If bypass doesn’t work, close one of the property editors or bypass the effect on a layer
by deselecting it.
When you select multiple nodes in the Effects Tree view, including a source generator, the bypass keyboard
shortcut (B) or Bypass command (on a node in the selection) will not always function. To work around this,
remove the source generator from your selection.
Source Generator Effects Require an Input when Used in Effects Tree
In the Effects Tree, some generated source clips, such as a gradient, timecode, or the 3D Warp, require an input.
To work around this, add a black source-generated clip as the input to these effects.
3D Warp May Cause System Failure when Using the Wave Scene
Copying or razoring clips using the 3D Warp Wave scene may cause a system failure in Avid|DS.
Ghosting in Viewer when Using DVE with Motion Blur
When using the Motion Blur option of the DVE, a ghosted image of the original position may sometimes appear in
the viewer. This is only a temporary refresh problem, which is corrected once you set a keyframe.
Flicker/Deflicker Effect Problem with Fast Flicker Rates
Since the reference regions of the black and white luminance levels are computed on a frame basis, there may be
problems when the flicker rates are faster than the frame rate. To work around this, deinterlace the source material
before you apply these effects.
