Why does movie time not equal to CD time??

[Lewzo]

I captured a movie from VDO tape player. It takes about 56 minutes but it get larger than 1 GB of harddisk.When I record the file it take more than 80 mins. How can I make a time match VCD file??

what format are u recording to .... vcd, svcd or dvd ???
what's the bitrate set at ... length of movie does not matter its the size that count
22.5 min dvd format
44-50 min svcd format
74-80 min vcd format ........per 700mb disk depending on bitrate & action in movie
a good rule of thumb is never try to burn more than the media ur burning to
even though u can fit 795mb per 700mb disk of media most authoring software use about 100mb of overhead so ur back to the original size of the disk
the only eception is ezcd creator (vcd only) it uses between 3-5mb of overhead

A lot of playback devices will display time counters based on the assumption that a CD is 74 min. long, regardless of the content. When I play my high bitrate XVCDs on my DVD player, for example, its seconds are shorter than real seconds, since its spinning faster than 1x to pull the data.

Forgot to mention this in my last post. Authoring software does not require 100MB overhead, unless you are formatting your disc as a packetCD, which is not playable in standalone devices. If it is requiring that much overhead, you're doing something wrong, or your authoring software is definitely not producing the CD to spec.

sorry ......most authoring software has a 15% overhead... assuming ur burning a full 700mb of media to your disk this would translate to 801mb file. but if you were only burning ..let say 35mb media it would be about 43mb file
sorry if i confused anyone, i always go on the upside to stay within limits.
the next time you burn (i use nero) ckeck to see what the output file is (it will say while ur burning (on the top right))
