You probably can load a sequence/stack of .png or .jpg files instead of an animated .gif maybe? (didn't try that myself in Avenue, but it was possible in res 2.41)
What is the difference between an animated .gif and a clip anyway? (I know the difference, but what are you trying to achieve?)
desktop: Windows 7 home premium 64 bit, MSI 870A-G54, AMD Phenom II X4 955 Black Edition, 4Gb RAM (GVP34GB1600C9DC), NVidia GTX 560

If you use PNG in losless mode the image quality will be the same as BMP.
We don't support animated GIFS's and loading multiple pictures in one clip is not possible a.t.m.
