FILE TO BIG, NEED HELP

[Sosua]

I dont know what is wrong. I did do the conversion of a Divx file to svcd. The file size is 495mg, 5.0.3 codex divx, 624+352, 29.970 fps. I did the conversion with TMPGEnc. I think i did everything that i had to do but my problem is that the file is about 1.2 gonce is finish. What is very funny is that it does that every now and then. I did extract the sound using VirtualDub. Where do i go wrong?? Why is my file so big?? Please help

How long is the clip? The Mpeg file size depends on the bitrate (Bits/second) times the length in seconds. Avi file size is irrelevant and movies will take 2 disks or more in SVCD format. Bitrate can be adjusted to change the file size but quality will suffer if you go too low.

If you use the Project Wizard in TMPGEnc it tells you the file size, which you can adjust. You can use the source range function to select which part of the movie to encode, then you can batch encode for the second part. 8)

Thanks for answering. It's 55 minutes. It's a television program. I did some before with succes but sometimes it is just to long. Im i doing something wrong? When you talk about the bitrate do you meen frame per second? It's 29.970 ps. Can you tell me what to do because i am newbee to this.

As zippy said, file saize is dictated like this
Length in seconds X(multiplied by) bits allocated each second (bit rate)

so a 55 minute file is 3300 seconds. so if you allocate 1000kb video and 192kb per second (ps) the filesize will be 3933600 kilobits. divide by eight to make 491700 kilobytes and divide by 1024 to make 480 megabytes. that fits on a cd. a video bitrate of 1782kbps and an audio bit rate of 192kbps is perfect to fit 55 mins on a disc. if you don;t want to get involved in the maths, don't do (S,X)VC/DV/D

That was nice of flaninacupboard to do the math, but it is a little complicated esp. for noobs. There's a bitrate calculator in the Tools section to help calculate the size.

If you're using the wizard in TMPGEnce then screen 4 is the bitrate setting window. Can't get any easier than that.

If you want to know about bitrate (or any other terms) check the Glossary section. 8)

Thanks, but dont think you understood my problem. I have this file witch is 495mgs. When i use the wizard and do everything it fits very well on a cd but after it is converted it makes a file of 1.2gs. It's like it takes my file + the audio file and count both of them so at the end my file is way to big. 1.2g does fit in one cd. Why when i do others in the series, some will work and some will gave me an enormous file? The others that i did had the same size. Sorry if i dont get it but like i told you i am new to this. It makes me mad when i wait 5 hrs to get a file that is way to big to put on a cd.

Anybody knows the answer to my problem? Why does my file so big after conversion?

[flaninacupboard]

as we both told you, file size is ONLY dictated by length and bitrate. it could be possible you are using an older version of tmpgenc, some of them had problems with bitrate allocation. download the newest version and try again.

I will do that. Thanks for your help
