Chances are the reason Poser cant import gif..is due to legal issues with Compuserve who owns the gif format..they tend to get a bit annoyed if you use their format in commercial apps..maybe the same reaosn for other formats as well.. also theres that 256 color issue with gif avi is really a good choice anyhow.because it can be imported as raw data i/e no compression..so what you work with is the actual footage.. besides once you export..you can always find a converter to do the change format job :)
