How is 4.2 gig output too much in TMPGEnc?

[jyeh74]

My total time for the mpgs that I wish to encode is 2 hrs 8 mins and 7 sec. Putting this into bitrate calc = 4531

When I put 4531 bitrate into TMPGEnc Xpress, output is 4405.78, BUT it shows this as 104.90% of capacity. It assumes it stops at 4.2 gig for some reason. How is this so if I have a 4.7 gig dvd-r?

4482MB is considered to be the maximum you can write to a single-layer DVD-R. TMPGEnc has always been wrong when calculating space. Some people say it's because they use 1000k instead of 1024k to represent a 1KB. The same as what hard drive manufacturers do. Just ignore the error and continue conversion. As long as it's below 4482MB you should be okay.

Now the TMPGEnc DVD Writing Tool that comes with DVD Author is another beast. It won't let you write anything greater than 4438MB to a single-layer disc. I use Nero to write the discs instead.

wile, why 4482. I tohught a dvd-r is 4.7 gig?

Check out "What is DVD" on the left





DVD-5, holds around 4 700 000 000 bytes and that is 4.37 computer GB where 1 kbyte is 1024 bytes* . DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Single Sided Single Layered. This is the most common DVD Media, often called 4.7 GB Media.

ok, i will assume 4482 is the highest I can go unless someone else lets me know. I dont see the math behind all this.

Why are people so obsessive about squeezing every last byte out of their DVDs? You won't see the difference between a 4.37 GB encode and a 4.2 GB encode. Do yourself a favor and leave a little extra space!

just trying to fit as many videos as i can on a dvd-r since i do not have double layer.

I think Nero will let me burn up to a 4.5 gigs max

Saying they hold 4.7GB is just marketing BS - as we all know, there are 1024 bytes in a kilobyte, not 1000.


A SL DVDR holds 4,700,000,000 bytes

4,700,000,000 / 1024 = 4589844 kilobytes

4589844 / 1024 = 4482 megabytes

4482 / 1024 = 4.377 gigabytes



TMPGEnc is just overly obsessive / conservative about exceeding capacity. 4405MB will be fine.

after i created the vob files using TDA, my 4405 became 4440 mb. I assume its due to the menus (even though I specified no menus?)

My question is how to use DVDShrink to burn it on a dvd-r?

[jimmalenko]

No need to use DVDShrink on anything less than 4482MB. Just burn using any burning software - Nero, RecordNow, ImgTools / DVDDecrypter, <gulp> roxio, etc etc ....

I never knew that it got so intricate on exactly how a computer calculated this. Now this is buggin me. I highlighted all of my files that I am experimenting with, control right and "properties" the total size = 4.28 GB. Now, using what jim stated 4.28 X 1024 = should give me 4382.72 MB.

When I "add" these files into TDA, the total comes out to 4444 MB. Where is the extra 4444- 4382.72 = 61.28? Just wondering why the numbers aren't matching up.

Cause 4444/1024 = 4.34 GB, not 4.28 GB.
Sorry for being so curious, I am just trying to see how these work out exactly.
