Minutes to MegaBytes or Gigabytes ???

[ridave]

Ok, I'm sorry if this is located elsewhere --I just can't find it or figure out what to call it ... and have never been able to search for results using many variations of terms .... Somebody must have figured it out before ...so I hope your out there. I have never been able to pre-plan an edited DVD based on time ... I know everything is rendered in hours, minutes, seconds, and frames. But how many minutes (of edited video) ACTUALLY equals a DVD disk ... in saving edited project from AVI to Edited DVD ... sometimes a 30 minute project is too big for 4.7GB disk other times 50 minutes will fit ... but you never know till you try and save your project ... I've tried to stay below 4.5 GB but have never been ablet to figure out how many minutes that is ... to give some room but still everytime my project is either too small or too big ... mostly too big ... is there a rule of thumb someplace, somewhere --nobody else ever seems to need or reference time in their projects ... to me it seems all other bases are covered ... but ya don't know if your project will fit till it's too late ... help

Hi dave

Any video under 60 minutes should fit on a Dvd.

The size of the Mpeg file used to burn a dvd is mainly controlled by the Bit Rate.
The larger the Bit Rate the larger the file size.
Quality is also associated with the bit rate in the same way.

Is there a rule of thumb someplace, somewhere you ask

To fit up to 60 minutes on a disc use 8000kb/s
To fit up to 90 minutes on a disc use 6000kb/s
To fit up to 120 minutes on a disc use 4000kb/s

To understand a little more read and use this:-

Hope this Helps

I am using VS8. I have copied 1 hour and 48 minutes of VHS video as mpg2 which ends up being about 6.5GB.

I want to burn it to a DVD. I create a simple, Automatic chaptering scheme of 15 minutes per section. That is the only "effect" applied to the video. No menus, no nothing.

In "Create Disk" of Share, I change the project setting's MPEG setting to Fair Quality, enough it says for 120 minutes of video, which reduces the movie to 4.03GB which should be within the amount of space available on the DVD.

I am using 4.7GB 8X DVD-R in a Sony DVD-RW.
The "Required/Available Harddrive" numbers show as 8.3/30.5GB
The "Required/Available Disc" numbers show as 4.2/4.8GB

After 5 hours of rendering (twice! just to see if there was a glitch) I end up with an alert box message telling me there is not enough disk space. I try another disk as the alert suggests and get the same results.

What gives? Any help?

Hi
Please read the recommended procedure from this posting:-

http://phpbb.ulead.com.tw/EN/viewtopic.php?t=27


2 / Your capture / clip settings maybe incorrect I think.
What are they?
Right click a clip in the timeline select properties what are they?

You need to ‘create a video file’ prior to making a dvd.
(as the recomended proceedure)

If your footage is 1hr 48 min then the bitrate should be about 4000.kb/s

From the project timeline after editing .Share—Create Video File
Use custom Mpeg files
Options—change the compression to 4000
If you are in a Pal area select Mpeg audio.

I use the bitrate calculator to help set my capture properties.

Now using the new file(which should be under 4.3 Gb)
Start a new project alter the project settings to match the new clip settings.
Share Create Disc.
You should not have to render again, you should not see the info window 'this will take some time to render'

Read my quick guide to mpeg from the link below, read 4000 for bit rate.

Hope this Helps

thanks for the previous reply ... I now have a better understanding of bit rates ...In finding some of what a lot of that alphabet soup IS actually is --is not easy ... probably because of inexperience and not understanding the termenology...
but what about this piece of advice ...
if your mpeg ... or avi files are a bit too long to fit on a standard 4.7 GB dvd ... it was suggested that the free program ... available out there on the internet ... called SHRINK DVD .... would shrink the original to fit 4.7 limit ... is this just a program that keep quality or does it automatically change bit rates to fit....?? Probably some place I should'nt even be going because all the other advice seems to be working perfectly ... but just had to ask and maybe someone else would like to know
thanks in advance
