Try trimming the video by a few frames or a few seconds and try to render the effect again.
A helpful trick: If you are not able to render a particular effect, or a Scene is not appearing in your bin after it has rendered, try switching projects, switching back, and then trying the render again. You might even try a brief shut down of the system and then reboot. Otherwise, try these tricks:

1. Make sure the hard drive is not full. Check your Project Settings menu to be sure the space used is not above the high 90 percent. We usually recommend having at least 10% of the drive available for rendering space. If the space is too full, you won't be able to render properly.

2. If you are in Dual Monitor mode or VGA mode, try switching to single video monitor mode.

3. Try moving the clips that won't accept a rendered filter to another project (using the clipboard function) and rendering in the new project. If its successful, move the effect back to the original project.

4. If all else fails send your video out to a DV tape and load it into an empty project. Replace the effects and render them in the new project.

TIPS:

-The Deshaker software is found in the "Special" in the main Edit menu. It cannot be used with Smart Rendering. If this function is active, the effect won't build.

-There is no printed manual for the program. Please use the "I" or Information button to get on screen descriptions about each mode.

-The different settings you can use will greatly affect how you stabilize an image. Changes can affect the border edge or the rendering speed of the filter. If some settings are changed to a higher level, a longer rendering period is needed. Please note that a clip with more violent shaking will be impossible to correct. Here is a good setup for a scene with minimal shake and having quicker rendering. Select a 5 second scene in the Edit Menu that has minimal shaking. Find "Deshaker" in the Special menu above the white line and choose these Settings:

DETECTION>Good
CORRECTION>Standard
BORDER CORRECTION> Reconstruction
DESHAKING>Medium

Then hit "OK" to close special and build the Deshaker filer on your clip. A new scene will appear in the scene bin that has the corrections.

-You can compare the new scene against the old one. Here's how you can see the difference.
1. Add the original scene to the storyboard.
2. Add the new scene copy with the Deshaker filer applied to it after the original clip on the storyboard.
3. Go to the main Transitions menu.
4. In Transitions, select the filer called "Split Screen" from the effects bin (Split Screen comes free with your Bonus Effects pack once you have registered your unit).
5. Click on "Add" to add the Split Screen filter onto the original scene and the Deshaker scene.
6. Set the Timer from 1:00 to the maximum allowable time. In this case, 5 seconds. This way the Split Screen effect will last the full duration of the two scenes.
7. Click on "Create" to render the Split Screen effect.
8. Then hit the Play arrow to playback the rendered filter. You can now compare how much more you stabilized the clip from the original

After clicking on Print, in the Print Label screen of Caladan, you can adjust the placement of the printed image on the paper or label. On the offset settings, 0,0mm means 0.0 millimeters. They use a comma instead of a period for the decimal point. So, to move the printed image 5mm to the left, set the horizontal offset to -5.0mm or -5,0mm. A positive number in the horizontal offset would move the image to the right. To move the image down 2mm, set the vertical offset at 2.0mm or 2,0mm. A negative number on the vertical offset would move the image up on the page
