Captivate and Alpha channel video insertion black background


i have been trying in vain insert green screen video captivate presentation. used serif moviemaker5 export video ".mov" chroma key transparency. works great if want overlay .mov format file on video in other sw platforms, when run through "adobe media encoder" (ame), background ends black. importing captivate ends black box containing subject of video on top of slide.

 

i think i've tried every setting in ame no luck.

 

i've seen problem elswhere on adobe forums, haven't seen solution. why black background after encoding ame, , there setting have missed? need start different format...say .avi, output doesn't give me option transparent or alpha output. problem seens ame, don't know sure.

 

any ideas? i'm using captivate 5 , serif, moviemaker 5 editing sw. output seems work everywhere in ".mov" format, not when converted .f4v ame

i don't know "serif movemaker", isn't possible export flv / f4v directly instead of .mov? use adobe premier or adobe after effects , here can export flv/f4v alpha channel works in captivate.
