Compression problem

[Angel-from-hell]

I'm making a video (home-made video with my camera) with pinnacle studio's 8. I combine video with photo.
Unless I don't use 'DV Video Encoder', the quality of my video is not good when there is a video-part (the photo parts are normally good).
Unfortunatly the video (who's only 30 minutes long), is 6,4 Gb.

I tried to use Xvid or DivX encoders to make the video; the quality is not much less, but it's still 3,5 Gb to make the movie of 30 minutes. If I lower the quality very much, it's only 600MB.
I don't understand how a popular movie hacked from the internet (ex: James bond), can be 700MB with a quality much higher then mine (30 minutes and 3,5Gb).
Does somebody know what's the most important for the quality? (the amount of images in a second, the kb/sec ...?) And maybe how I would become a 'smaller' size but still a good quality?

Tnx, Greetings

quality depends on many factors, but in your case codec settings, bitrate and probably deinterlacing (or lack thereof?). what i suggest is to encode to DV with all transitions etc with pinnacle studio then encode to xvid afterwards.

do a 2-pass xvid encode, max motion search and VHQ, enable qpel & GMC. you could deinterlace (preferred) or keep it interlaced if using xvid. set bitrate ~1500kbps
