Confused on file sizes!

[sdr]

As a newbie I am trying to get to grips with sizes. If I capture 1 hr of Video, it roughly is 12Gb of AVI or 4Gb of MPEG format. If I want to put this on one CD (VCD say) which is 650mb, how will it fit on 1 CD? I have come accross 1.5hrs of film on 2 VCDs. Is there a table/formula to calculate this please?

Also as a newbie I came up with the same problem. I had 1 hour of the movie encoding as a 2.5Gb mpeg file. Then I found where I made my mistake. When I loaded a template in TMPCEnc I loaded the wrong one. I had clicked on the NTSCFilm template. After re-encoding the movie with the NTSC template now it comes out around 600 mb for about a hour of the movie.
You might want to check what template you had used.

Good question.

A standard VCD will use about 10Meg/Minute at 352*288, 15 frames per second. So this means you can fit 60-65 minutes on a 650MB CD, but if you start upping the data rate from 1150 to, for example, 1500 or more, you are going to get a better picture, but also less on a CD. Also, an increase in resolution will also dramatically reduce the available length per CD.

Modifying settings to produce an XVCD can suit some people, and give excellent results... but don't forget they wont always play on all DVD players.

Standard VCD PAL is 352x288 25fps MPEG-1 1150kbps Mpeg-1 Audio Layer-2 224kbps
Standard VCD NTSC is 352x240 29,97 fps MPEG-1 1150kbps MPEG-1 Audio Layer-2 224 kbps
This means, you can fit 74 minutes on a 650MB CD (because a VCD is burnt in MODE2)
A higher resolution does not effect the filesize.
Don't hesitate to read the "what is.." and "how to.." sections.
