CCE Basic CBR System Average Bit Rate Video Settings

[gkoz]

1. Does the average bit rate setting increase or decrease only in 500kb increments?

2. When I adjust the average bit rate setting down so that I can fit a large mpeg 2 file onto one 4.7gb DVD-R disc, approximately what should the file size be in kbs?


I currently use TMPGENC Plus and it's easy to fit a large file onto DVD because I adjust the file size to 96% -and there are no problems - BUT it's SO SLOW TO ENCODE!


Thanks for any advice.

Hi,

1. Does the average bit rate setting increase or decrease only in 500kb increments?

Well, yes, it is default and can be changed. I don't know how though. But you can type the bitrate from keyboard

2. When I adjust the average bit rate setting down so that I can fit a large mpeg 2 file onto one 4.7gb DVD-R disc, approximately what should the file size be in kbs?

I think it should be approximately 4.7 million kbs
And the last: if you need to adjust the size only with 96% it is not large.

I'm not sure I follow what you are saying. As mentioned, you should be able to type in whatever bitrate you want. I haven't used TMPG for a while though. Also as mentioned, you should set your total bitrate (including audio) up to where you don't exceed 4.7GB. A bitrate calculator will help you do this (leave some room for error). As you already learned, TMPG is a popular but slow encoder. CCE basic is in the same price range and is much faster. Unfortunately, it's less user friendly.

Thanks for replying.

I've done some investigating. I can't type in the bitrate I want after using a bit rate calculator but what I can do is alter the average bit rate by changing the file size.

So my question is what should be the maximum file size of what I've captured to fit onto a 4.7gb DVD-R.

I know the size of my captured file size can't be 4.7gb because it won't fit.

Captured or encoded? If you mean what should your final size be after encoding to fit on a DVD-R, don't forget about the authoring and menus. If you use very basic menus (still images) then you only need to reserve a few MB's (at most) for the authoring & menus. If you use complex menus then that may require several hundred MBs. Bottom line, get video + audio + menus as close to 4,700,000, 000 bytes as you can without going over.

If you know how long your movie is, and put that into the bitrate calculator, it will give the bitrate required to encode an mpeg-2 to the size required to fit on a DVD. If you can't get it exact, go to the largest increment under the size int he bitrate calculator and live with the spare space.

Sorry, I meant encoded. How large should the encoded file be to fit onto DVD-R before authoring.

Thank you. I think I know what to do now.

I only do basic authoring. Inserting 10 chapters or so into the file.
