It allows you to control how the images of Scene Strips are displayed in the preview.
- OpenGL Preview
Use a quick OpenGL preview (see OpenGL render for more on this subject), otherwise a full render is used, which can be very slow.
- Sequencer Preview Shading
Method for rendering OpenGL renders. See the 3D View’s Viewport Shading options.
- Textured Solid
Display textures even when in solid mode.
Settings used by OpenGL Previews:
The anti-alias setting from the active scene is used for all scenes.
The alpha setting is taken from each scene strip Alpha Mode option.
- Show Overexposed
Shows overexposed (bright white) areas using a zebra pattern. The threshold can be adjust with the slider.
- Proxy Render Size
Size to display proxies at in the preview region. Using a smaller preview size will increase speed.
Shows guides used to position elements to ensure that the most important parts of the video can be seen across all screens.
