i don't know if is a question for cineform or adobe developers

if i have a 3d cineform file, and i try to use the tool Project manager, i cannot create a new project with cut, be cause premiere simple copy the entire clip, and not do a cut only the used part of clip in editing.

i tested it also in the last premiere cs.5.5 and it copy full file, it not cut it.

i verified that a free utility like virtual dub can cut easely the file in direct stream way, that keep all quality of original clip, i think that is an adobe limits, but i ask here to know if i do some error.

but in a big editing session is complex to cut all part with virtual dub.
