Cut AVI using VirtualDUB

[manub]

I've captured an Huffyuv AVI with my capture card (PCM Audio 44.1Khz 16 bit Stereo) and using VirtualDUB. Now I need to cut something. Two questions :

1 - Work for Video and Audio is to be set at Direct Copy Stream ? (I will compress later)

2 - Since the file is sized almost 50GB I haven't got disk space to make a copy. Can I cut it and then save by overwriting existing file ?

1. yes.

2. no.

RE #2:

If you're converting to mpeg then I suggest frameserving. No filesaving required, look it up in the guides.
