I am looking at building a PC just for video editing. However I haven't bought a digital video cam. yet and was wondering what the size (mb/sec) of like standard digital video from a nice home camera would be. Any help is appreicated.
 
i have a 640x480 clip that i brought into premier from my sony dv cam using the 'DV-NTSC Standard 32khz audio' setting. its 107 seconds long and 384megs in size. thats about 3.5MB/s with audio.

width * height * color bit depth / 8 = size of one frame in bytes. For 640x480 with 32-bit color, that's 1,228,800 bytes/frame. At 30fps, that would come out to 36,864,000 bytes/sec, or about 35MB/sec uncompressed. MPEG-2 or MPEG-4 compression can cut that down quite a bit, though.

Uncompressed CD-quality audio (44khz, 16-bit, stereo) is about 10MB/minute. Lower-quality uncompressed audio (22khz, 12-bit, mono) is about 2MB/minute. 128kbps MP3 files are just about 1MB/minute.
