DVD9=>DVD5, DVDShrink@4.35GB, DVDFab@4.19GB

[CobraPilot]

Out of curiosity, on a DVD that DVDShrink would handle, I compared the resultant size of a full-disc DVD9 to DVD5 shrink size to that of the 30-day trial of DVDFab full-disc shrink size, with the results as in the title:

o DVDShrink produced a 4.35GB file, the typical maximum capacity of a DVD5 disc, which I've always assumed meant the program was making best use of available disc space.

o DVDFab produced a 4.19GB disc, considerably less than the maximum.

While the resultant video quality seems roughly the same (a "calibrated eyeball" opinion), it surprised me that there was what appears to be "overshrinking" with DVDFab, wasting available space on a DVD5.

Just a one-disc comparison . . . .

It's typical of conversion programs to undersize the output. DVD Shrink is somewhat unusual in being able to nail the output size. I have DVD Shrink set to output 4478 MB's. I doubt anyone could see a qaulity difference between 4.35 and 4.19.

You can go into the prefs of both programs and set the output to any specific size you want.
4400, 4390, ect

The "programmer" just set them as default to whatever size they are at install.

Some people like them a little undersized so the disc does not burn right to the outer edge, which is a problem with some cheap media.

What's the problem then?..Just b/c the disc is not completely filled, doesn't necessarily mean it's of a less quality copy..
Let your eyes be the judge..Which seems like you've already done..Two different but similar tools/apps..

Data errors are usually more prominent near the outer edge of the disc. I always prefer to go a little bit under the max capacity, just to minimize the chance of playback problems. A 4.19gb file size sounds mighty fine.

The point is kind of moot anyways seeing as you can change the exact output size in both programs

Sorry we're keeping you up, t0nee1! Feel free to ignore any of my posts you don't find intellectually stimulating! I promise not to take it personally . . .

My initial post wasn't to point out any sort of problem, just to share some observations of a little test I ran, hoping to learn from others' comments---which was the case most of the time. For example, I hadn't considered that errors on discs often are more prevalent near the edges.

Obviously, there might be a more noticeable degradation if the original video requires more compression, where that extra space might be put to better use. "Calibrated eyeballs" again . . . maybe . . .

Is someone baking brownies ?

Sounds like someone's taking it personally to me!..
I don't smell the brownies, but I'm smelling the egofarts...

T out, I'm bored, err tired!..

Cobrapilot, I have also noticed this as well and apprciate the post. I just stick with Shrink since it seems like more eficient use of space. I have never had issues with the outer edge, but I also try and stick with top notch media so that may be why. I liken it to finishing the last swig of beer in the bottle. Sure, i'll still catch a buzz but why waste that last drop!

Exactly!!
On all points
Except i drink straight Bourbon so i don't have that problem of the last swig of flat warm beer

I always use Verbatim and usually squeeze every last bit out of them with no problems.
There was a time just for fun i would even overburn dvdr's just to see if i could!!
LOL!!
Unless i am encoding a video myself and it's not long enough to fill up a disc at 8-9000Kbps.

If i remember correctly, DVD Rebuilder actually fills a dvdr by default more than either DVD Shrink or DVDFab, which is what i use with CCE when i want a really good DVDR copy of something & when it need's a good squeezing down.

bypassing personal stimuli.
straight to the point.

I never used DVDFab before so can not tell much.
I love using DVDShrink all the times, yeah in DVDShrink you can rip max. up to 4464MB = 4.53GB
plus DVDShrink offers a unique feature for Quality Enhancement for old DVDwith some built in profile.
This feature takes bit longer to rip DVD but quality is better for old movie dvd.

DVDFab produced a 4.19GB disc, while DVDShrink produces 4.365 GB DVD.
the difference approx 164 MB, does not result in much difference in video bit rates. Of course 4.19GB produces slightly less video bit rates (considering audio having same specs) but at a 23.976 or 29.97 FPS it is very difficult for human eyes to notice it.
