Well, I have found myself with 5 hours of HDV m2t files to edit in Vegas, which I will then export to MPEG2 for DVD

But....

I am looking at chroma keying. The footage is of a building site (the new school being built), and I would like to take footage of a woman presenter in studio to overlay onto the building site as if she is there on site.

I read Alan Mills post and thought, yeah, I warm to idea that I have a HDV original I can export in future in format superior to mpg2 (especially since this is a presentation the scool might liekt o show on big screen one day), and then I read Marks reply about playing with HDV/ chroma keying and also wondered about my PC spec. Apart from taking a long time to load up the project files Ive not encountered any problems as yet. Please tell me, what kind of editing really hogs CPU bandwith? Things like chroma keying in particular? Or just a bundle of effects which MArk seems to work with loads?

This PC is 2.5 yrs old. Its Athlon 64 3000+ . It supports Dual channel but I know the CPU is Single CHannel 1.8MHz. 1Gb RAM. 256K Shared Video Adapter. My gut feeling is that Im on the edge with this spec for HDV editing. I am open to upgrading the PC and am interested to know what would do the job without going overboard.

Thanks
