SINCE RB 0.93.2 - Video Always oversized

[humax]

Hi
Im using RB 0.93.2 - Pro Version.
Since this Version ervery Backup is to big.
In Special Options i have Target Sectors 226000 but its always 8-25 MB Oversized.
Using Avisynth 2.55
and CCE 2.70
Anyone can help ??

thx

with targetsectors at 226000 you should get the opposite, a severely undersized output. try taking that line out or any other sectors settings you have (cce,hc,etc.) and see if you still get oversized. I myself use 2261000 and it works well 99% of the time.

sorry forget a 0
its 2260000 but oversized.

Same for me on pro. If I use 2260000 it's oversized.
I have changed it to 2256000 and it's better, but still
a little big. Next time I will drop it some more.

It's not always the same though for every movie. Some larger then others.
So it has been a constant tweak.
I use CCE 2.70.02.00 and Avisynth 2.55.

If you are using a Matrix other than the default you can get very different outputs depending on which one you are using.

I have encoded the same movie with different Matrices and get vastly different outputs.

I've recently imported some wild Matrices with the NEW Rockas Rebuilder Matrix Editor. It now supports direct import of .CQM and .XCM Matrices.

The default is 2236400. If you don't want to oversize you should leave it at the default. If you change it, you aren't "getting oversizing" --> you have to accept the risk of oversizing with your decision to change it.

I added that hidden option at the request of someone here on the forum and have regretted it ever since.

OK

with 2255000 its perfect. So i will use this target sectors.

lol it's amazing how often these issues keep coming up as 'problems' when they've tweaked the targetsectors. Doesn't anyone research anymore before they post?

Just an idea, but it may save you some headaches in the future.

Have a "Reset TargetSectors to Default" setting in the interface.

Just a thought.

I keep 4 different target sector sizes in my rebuilder.ini file and have to comment out the ones i don't use. It would be great if the gui could have a select output size option. Most of my backups are in CVD format (half-D) and I can compress a 6-7 gig vid to about 1.6 gigs (the same as a 2 CD SVCD rip) so long as the run time is less than 2 hrs. 20 mins. For longer vids (i.e. 3 hr porn vids, I have to up the output size to either 2 gigs or 2.4 gigs), and for vids that I do not need to transfer via the net, I use the default size. These are my settings:

[Video Sizes]
x-TargetSectors=2236400
x-TargetSectors=1228800
x-TargetSectors=1024000
TargetSectors=819200

As shown, that is for a 1.6 gig video. Still, I have to open the rebuilder.ini file and make the change before I can open the program. That's not a lot of fun compared to just clicking on the icon on my desktop. Maybe that could be a pro option. I would gladly support that change with another contribution.

I understand your pain jdobbs...but some of us contributors appreciate you adding our suggestions. Maybe documenting the hidden options and how they work like AutoGK does might be a solution. You could even use links to threads about them here to Doom9.

Thanks :D

My confusion is over the huge difference one video can be over another with the same setting.
If each sector is a certain size then shouldn't the output size be the same?
Or is it that each sector has different compression levels and thus you can end up with a larger or smaller file?

I have one video that with 2260000 it comes out right at 4.37, but on another with the same targetsector size it comes out at 4.22. If I leave it at default it's less then 4.

I am not asking for a change in the program, but an explanation of why that might help me to make more informed choices on what to use, if that is possible.

Thanks,
Mark

I would wager that the difficulty you are experiencing in getting to the targetsizes is due to differing Q values in your sources.

[jdobbs]

The accuracy of the output differs considerably from one encoder to another. It can even shift based upon the complexity of the source. Also, if you are using one-pass encoding the sizing is inherently inaccurate. To make it even more difficult is the fact that CCE can limit the sizing of an output to a point at which the quality has reached what it considers perfect (Q = 1).

You would think that the same bitrate would always come out to the same size -- but sometimes it just doesn't.

[markrb]

Just to clarify I have used both CCE 2.50 and 2.70.02.
All with default matrix's and 4 pass VBR.
There seems to be no difference in the final size based on the version
of encoder give or take a MB.

Thanks,
Mark

[jdobbs]

Now do the same source with QuEnc or HC -- you will see a difference in size even though the source and bitrates are all exactly the same. Then do another source that has the exact same number of frames with the same exact bitrates on the same encoder... it will be different again...

If you use the same encoder engine (e.g. CCE) on the same source you'll get no change at all except the tiny bit related to version changes.

The changes aren't huge -- but are sometimes in the 1-2% range, which is about where you will see the default TargeSectors fall...

i just did my first rip using rebuilder. I use the newest free version. It was a multiangled pal music dvd and ended up oversized with about 100MB. So this isnt just a problem if you are playing with the settings cause i havent.

how big were the angles? if too big rebuilder might not be able to compress enough to even get to dvd5 b/c of minimum bitrate requirements

also what was your encoder? as many have said all rebuilder can do is request a bitrate, the encoder determines how close it can get.

I used CCE version 2.67.00.23. I dont know how big the angles where, but main movie with angels where 5.97GB and the extras where 1.53GB. I had max compression on extras.

Good thing i dont care about extras so i can just strip them and get a burnable dvd.
