why are my MOV file so incredibly huge?

[Bansaw]

I am using Sony Vegas 6.0, and am wanting to creat quicktime MOV files for display on the web.

I was, for example, converting a 100MB video file into MOV and adjusted the dimensions to:

320x240
Quality: Preview 50%
32bpp color
NTSC
Audio uncompressed 44,100 16b

This creates a 1GB (!) file.

Why the perplexingly huge MOV file?

Because you didn't select an appropriate compression codec or you picked a high bitrate.

Uncompressed RGB32 at 320x240, 25 fps would be about 460 MB/min. Plus audio.

There is a "video format" pull down box.
At the moment I have "None", but theres a whole list of them such as:
Animation
H.261
H.264
JPEG 2000
PHOTOJPG
Planar RGB
PNG
Sorensen
TGA
TIFF
etc etc

Which one is the best (for web)?

[Soopafresh]

1) h264 (best compression vs quality ratio)

2) Sorensen

Vegas makes a LOUSY H264 file
Use sorensen or get PREMIERE PRO or QUICKTIME PRO ($20) to make .H264
