  Why do I have a different result in my final render out compared to my Camera view in Digital Pro? (Export)

DP0007: Why do I have different result in my final render out comparing to my camera view in Digital Pro? (Export)


Difference between Camera view and Render view

GLOSSARY
Camera view: OpenGL display view that provides the quick display for sceneplanning.

Render view: Quick preview of how your final render will look. Use this to to check your effects.

There are many reasons for a different result between the Camera view and final render out, especially when you have effects (Cutter, Blur, Transparency) that do not show correctly in the Camera view, but appear correctly in the Render view.
Different results occur depending if you render a scene or if you view it in the Camera view.  This is because when you use the Camera view, Digital Pro makes use of a quick display which, to save time, does not render every effect.  Because of this it is important to check the effects in the render view, as this is exactly the same as the final rendered image/movie.


Difference between SWF, Quick Time movie, OpenGL frames and Render network.

GLOSSARY

Display module: Use this to see the result of the art work that is attached in the Network view. Using multiple display modules allows you to see many different aspects independent from the Camera view. 


Write Module: Use this to render individual image files or create a QuickTime movie on you system. Connect several write modules connected to render in different resolutions or file formats at the same time.

Export: The four export (render) options rely on Display (Display all) or Write modules..

The situation sometimes happens when you export with QuickTime movie as opposed to the  Render network.  Exporting to QuickTime uses the Display module while the exporting to the Render network uses the Write module. In other words, the Display module you have chosen can be connected in a different location from where the Write module is connected. When this happens, this may result in the  Render output file being different from SWF, QuickTime movie, or OpenGL frames.

Here is an example of which option uses which module.
  • Display Module: SWF, QuickTime movie, OpenGL frames
  • Write Module: Render Network
All SWF, Quick Time movie and OpenGL frames has an option to select which display (display all) you want to use to render. However, unlike the Render network option, you only can select one display.
The Render network option let you render multiple formats at the same time by adding extra write module. This is very helpful when you export two different resolutions (ex, NTSC and low-res for the fast view).

NOTE:
Rendering multiple formats at the same time requires significant hardware resources which will crash if the memory limit is exceeded. This will be more critical depending on the complexity of the scene. Using the  ‘Enable External Read Image is bigger than [ ] times the final Resolution’ option from Preferences > Network tab will let you render in a separate memory location and help alleviate the memory full crash problem
