BluffTitler relies on hardware antialiasing when playing the animation in realtime.

No Antialiasing

Without antialiasing the jaggies are clearly visible, especially when using low resolutions, complementary colours and lines that are nearly horizontal or vertical.

Hardware Antialiasing

All modern graphics cards support hardware antialiasing. This picture has been rendered by a NVIDIA 6600 GT. Now, that looks a lot better!

You can turn on hardware antialiasing on by right clicking on the desktop and selecting properties > settings > advanced on XP and personalize > display settings > advanced on Vista. You will find a submenu where you can choose between performance and quality. When you choose quality the jaggies will be gone.

Update the driver of your graphics card

Make sure the driver of your graphics card is up-to-date. Failing to get hardware antialiasing to work can sometimes be fixed by updating the graphics driver.

You can download the latest driver from the website of your video card's manufacturer. For example if you own a GeForce card go to www.nvidia.com and if you have a Radeon visit www.amd.com. Do not forget to install the driver after downloading.

When exporting your animation as a picture or movie file you can choose between hardware, software and shader antialiasing. You can find the antialiasing quality dropdown list box in the File > Export as Picture... and File > Export as Movie... dialogs.

Hardware Antialiasing

Hardware antialiasing is fast and does not require much memory. It has however two limitations: you have to keep the render window completely visible and you can't create resolutions bigger than your desktop.

Software Antialiasing

Software antialiasing is slower and requires a lot of extra video memory, but offers better quality, you don't have to keep the render window completely visible and you can create resolutions bigger than your desktop.

Shader Antialiasing

Shader Antialiasing is super fast and matches the quality of software antialiasing, but requires a graphics card that supports shader version 3.0

Fighting video driver bugs

Antialiasing requires lots of memory that can confuse some video drivers. If your output is black or contains crap, your video driver is reckless and needs to be corrected manually: switch to Medium or Low Quality and the problem is fixed.

Free memory for better software/shader antialiasing quality

Antialiasing requires lots of memory, system memory and video memory. System memory is usually not a problem, but the available video memory can be a problem when exporting HD resolutions. You can free video memory in the following ways:

• Close all other applications
• Use a smaller BluffTitler render window (by setting the view value to 50% or 25% in the File > Set Show Resolution... dialog)
• Use a smaller desktop resolution
• Turn off hardware antialiasing
• Install a graphics card with more memory (HD resolutions in high quality require at least 256MB)

In the dialog that is presented after creating a picture or video file you can see the antialiasing quality. Depending on the choosen antialiasing quality and the available memory this value ranges from 16 samples per pixel (very good quality) to only 1 sample per pixel (no antialiasing).
