In order to do effects which involve alpha channels, a colormodel with an alpha channel must be selected. These are RGBA-8 bit, YUVA-8 bit, and RGBA-Float. - The 4 channel colormodels are slower than 3 channel colormodels, with the slowest being RGBA-Float. + The 4 channel colormodels are slower than 3\,channel colormodels, with the slowest being RGBA-Float. Some effects, like fade, work around the need for alpha channels while other effects, like chromakey, require an alpha channel in order to be functional. So in order to get faster results, it is always a good idea to try the effect without alpha channels to see if it works before settling on an alpha channel and slowing it down.
