how many MB equal GB/ how many episodes can i fit on disc?

[janeydoll]

I have a few questions.

How many MB equal a GB? each episode i have is around 700mb

They were recorded on my standalone harddrive on SP so I can fit only 5 on a disc.

Is there a way I can reduce the size to maybe fit a few more on a disc, I would love 8 on a disc, but anything would be better than 5, without losing quality? they are recorded on nick at nite and look absolutely flawless.

they show the video data rate is 9558 (if that matters) audio bit rate is 256 kbps.

i use Ulead video studio and i can change the quality from 70 percent all the way up to 100 percent if that matters also.

if someone could help me tonight that would be awesome, i am needing to figure out how many i will be able to fit on a disc.

thanks so much

let's see...1000mb is 1gb
try a bitrate calculator in the tools department

1000MB=1GB. If your bitrate is 9558kbps, they probably do look good. That's a very high bitrate. Try dropping that down to about 7000kbps. Encode a short representative clip of about 5 minutes to see how it looks.

But there is an easier way to figure this all out. Use a bitrate calculator. You will find them in 'Tools' to the left. You set the total running time of all your videos that you want on the disc and the size of your disc. It will tell you the bitrate needed to fit them on the disc. If your bitrate gets down to about 2500kbps to 3000kbps, you might want to think about using 1/2 D1 frame size. If you look to the upper left in 'What is' DVD you will see Full D1 and 1/2 D1. 1/2 D1 makes better use of the lower bitrates. If your original source is TV, you will likely not see much difference in quality between the two sizes.

I'm assuming you are looking to encode to MPEG-2 video and make a standard DVD that will play on a settop player.

1024 MB = 1 GB
1000 MB = 0.97656 GB

Some convertors:

Hard drive and DVD manufactureres (and not some other people) round off to 1000 MB (in the case of hard drives and DVDs they do it because they can make the HD or disc sound bigger than it really is.

There are several ways you can reduce the size to fit on disk. You could just author a disk with 5 (or 6, 7, or 8) episodes on a disk, then use DVDShrink to reduce the author files to fit on 1 disk.

You could reencode the files to fit more on a disk.

Anything you do to reduce the file size will affect quality. The question (which only you can answer) is whether it reduces the quality noticably or whether the reduced quality is acceptable. Generally, if I record something on SP on my standalone, I can reduce it 10-20% when I reauthor and don't notice the difference. If I reencode to 1/2 D-1 then I'll go even lower and it's acceptable to me (I can't see the difference on my TV).

It's not uncommon for files recorded on a standalone recorder to show a bitrate of 9500+ when you bring them into the computer regardless of what they were recorded at.

If each episode is around 700 MB then you can fit 6 episodes on one single layer DVD or 11 episodes on a dual layer DVD without reencoding to a lower bitrate.

6*700 = 4200 MB
11*700 = 7700 MB

A single layer DVD holds 4482 MB and a double layer DVD holds 8144 MB (when a MB = 1024 KB and a KB = 1024 byte).

How many minutes is each episode? If each episode is 30 minutes then 6 episodes would be 3 hours and then the bitrate would be something like 3000 kbit/s which is very low for full D1 and good for half D1 resolution. In that case I would not bother reducing bitrate any more to fit more episodes per disc. Use more discs instead. Personally I never put more than 3 hours per disc at halfD1 resolution from analog captured video because I want good quality.

1 Byte = 8 bits
1 kiloByte ( kb ) = 1 024 Bytes
1 megaByte (Mb) = 1 024 kb = 1 048 576 Bytes
1 gigaByte (Gb) = 1 024 Mb = 1 073 741 824 Bytes
1 teraByte (Tb) = 1 024 Gb = 1 099 511 627 776 Bytes
1 petaByte (Pb) = 1 024 Tb = 1 125 899 906 842 624 Bytes

Hope it hepls

If your player supports it you can use a more efficient video codec.

For instance, if your original files are MPEG2, you can get similar quality with Xvid (in an AVI file) in 1/2 or 1/3 the size.
If you can use x264 (in MKV) you can reduce the size by another 30-50%.

You can also save some MB if you compress the audio more.

You have to experiment to see what settings give the result you like.
