BD9 but space not completely used

[emilio99]

Quick question.

I tried to convert a full BD to BD9 (high quality; force 2-pass) but the result has only 7,09 GB (7.614.640.704 Bytes) (Bitrate 6312).

Target size is unchanged and set to:
TARGET_SIZE=8422162432

How can I improve the used space to increase the bitrate?

By default bd-rb leave some space at the end to compensate for errors caused by writing in outer layer of disk. It is also there to give cushion in case encoder does not stick to target.

You can overwrite it, but doing at your own risk. Choose custom size for output. Max you can go is 7.95 GB remaining is reserved and not accessible to user.

[RobertM]

You go to the 'settings>setup' screen in BD-RB, and define the 'custom target size' (bottom right corner) to whatever you want. Then select this custom target from the "Settings>Output options" dialogue. Remember that the default BD-9 size is 7.84 GB, or 8032 MB. If you want the output 10% larger than what you got initially then set the custom target size to 8032 + 10%, or 8835 MB.

Hi!

Unless your initial (converted to) BD-9 yields some specific visual deficiencies, I'd suggest that there is no purpose/benefit of altering your settings simply for the sake of using more disc space...

I had a similar issue with BD5 encodes. After some trial and error (lots), this simple formula does the trick.

We know the BD5/BD9 default TARGET SIZE, via the Setup section:
BD5 = 4469 (~4.36GB)
BD9 = 8032 (~7.84GB)

Ideally, the encodes would finish at or near the upper limit (BD5 ~ 4.37GB and BD9 ~7.95GB). They don't, which is fine. For the last few BD-RB versions, my BD5 encodes have generally been in the 4.22-4.25GB range...on the 1st try. This leaves approximately 100MB+ empty space...so it's about 97% full. Excellent, but is there a way to squeeze it even closer?

I've been able to consistently get my ISOs to within 0.1% of the max DVD+RW upper limit on 2nd try. Further down, I reveal the advanced formula for reaching that limit.

Just for information purposes:

1) I use DVD+RW for testing afterward, before burn to DVD-R. Sadly, there is no DVD+RW DL that I know of. In addition, DVD-R DL (BD9) are same price (or more) than BD-R (BD25). Otherwise, I'd be making BD9s and DVD-9s.

2) DVD+RW upper data limit is "slightly" smaller than DVD-R, but only by 0.147% (negligible).

See this link for more info:
http://en.wikipedia.org/wiki/DVD-R

The advanced formula is now revealed:

Lets say we encode a BD5 at default (shows "4469 Megabytes" in Custom Target Size of Setup) and it encodes to 4.25GB (folder, not ISO). To get it closer to the maximum size, try this:

For BD5:

C = Default Target Size (4469)
B = Actual Result (4.25GB * 10)
A = Factor
D = Desired Result (4.37GB * 10---can use 4.36GB if desired)
E = New Target Size

Step 1)

Formula: C/B = A

Example:
4469/425 = 10.51529411764706

Step 2)

Formula: A*D = E

Example:
10.51529411764706 * 437 = 4595 (new custom target size)

Notes:

1) Not exact, but very, very close...sometimes i estimate result between D = 436 and D = 437

2) Be sure to uncheck "Write to ISO" in BD-RB settings. Then you only create folder (not ISO). This helps, because now you can manually use ImgBurn to determine ISO size (prior to burn, ImgBurn shows total bytes in small popup box). If result is not as desired, edit custom target size in BD-RB and encode again.

3) I've only used this for BD5, not BD9...logically, it should work the same.

For BD9:

C = Default Target Size (8032)
B = Actual Result (7.09GB * 10)
A = Factor
D = Desired Result (7.95GB * 10---can use 7.84GB if desired)
E = New Target Size

Step 1)

Formula: C/B = A

Example:
8032/709 = 11.32863187588152

Step 2)

Formula: A*D = E

Example:
11.32863187588152 * 795 = 9006 (new custom target size)
11.32863187588152 * 784 = 8881

-------------------------------------------

As you can see, the formula is simple, not advanced :) It works like a charm on BD5 encodes. I hope it works on your BD9's also, but I cannot guaranty anything. Testing is the only way, and can get expensive with DVD-R DL or DVD+R DL discs.

Why, when you can never tell the difference regardless of any info that you can provide to say otherwise. The eyes don't lie.

Faster, more accurate method now...strictly for BD5 perfectionists with ADD, ADHD or nothing better to do.

How to reach the size limit for BD50 to BD5 using custom setting:

1. Create a BD5 in BD-RB using BD5 default target size (BD5 = 4469), but save to folder, not ISO (iso adds about 1MB to folder size).

2. When finished, right-click the BD5 folder, then click Properties to see the exact size in bits. Use the first 4 numbers and subtract them from 4695 (that's the goal i use, approx 4,695,000,000 bits, about 5MB less than the max size possible).

3. Example: (let's say that folder Properties show something like 4,421,345,678). Just use 4421 from that number. So, 4695 - 4421 = 274. Then add it to the default target size to get a new, more accurate custom size. Example: 4469 + 274 = 4743.

4. Use that number (e.g. 4473) in the custom target size to re-build your BD5 a second time. Output will be VERY close to your target, but not always perfect. If too high (or low), check folder > Properties again for the first 4 numbers.

5. Whatever the difference from your goal, subtract (or add) that difference to the BD-RB custom target size and try a 3rd time. Should be right on target.

6. Similar method should work for BD9 and BD25 also (just more time consuming, as if this wasn't way too time consuming to begin with). :D :eek:

Hope this all makes sense. I know most will say it's a waste of time and you could be right. All my BD5 ISOs are 4.37GB (roughly 4,594,000,000 to 4,598,000,000). Just saying....

PS: if anyone knows how to set a custom target size for DVD5, I'd love to hear about it. Like BD5, the output size is usually ok, but varies in size and is quite a bit smaller than max. The option to change the target size is grayed-out when creating DVD5.

Thanks,

Fine, but it has been said many times that it is not even advisable to fill a disc close to 100% because the outer range is most prone to burning errors and mechanical damage through disc handling.
But to each his own ....... :-)

[jdobbs]

Let me make it perfectly clear. DO NOT post bug reports if you change those settings. I consider it a self-inflicted problem. There are very good reasons why BD-RB uses the settings it does -- and when you change them, YOU are responsible for the results.
