My DVD Shrink operates on an average of about 2,300 KB/s. Sometimes less and sometimes more.

My question is what decides this? Is it my hard drive speed, my memory, or DVD Shrink? I was hoping for some higher rates. Any info would be appreciated. Thanks!

Your processor and ram usually affects the speed at which dvd shrink analyzes and encodes. Faster processor,faster encoding. Your processor will run at max speed during both slow analyzing and encoding to your harddrive. You can free up some memory by not multi-tasking and shutting off all background programs.

I'm not sure about the Hard drive speed. Majority are 7200 rpms and newer ones are 10,000 rpms. I'm am curious about how that may affect the encoding speed.

The compression and quality enhancements are the ones affected by the speed. Higher the compression,the longer it takes to encode. Adding the enhancements of slow adaptive error compensation in the backup options can really slow down that backup.Your kbs per sec will be reduced. This is where those times will really be magnefied by the smaller processors.

To help speed you up, You can re-author,cut out extra audio streams,directors commentary,sub pictures,extra main movies when multiple main movies are on the dvd,beginning and ending credits. This reduces the compression=no need for the quality enhancements most of the time. Unfortunantly you lose the menu function,but speed will drastically increase.

I appreciate your input. Thank-you. Ya, I am still learning alot about DVD Shrink. I see all the sounds listed that I have the option of taking off but I am reluctant to remove anything due to not having the knowledge of what does what.

It's easy. Majority of my backups are Main-Movie only,AC3 5.1CH ENGLISH audio stream only,delete all the other crap,and can further reduce that compression by cutting off the ending credits,just enough so you can read the actors names with their characters.


After DVD Shrink does the initial analyzation and opens up the files:

Click the Re-Author tab

Find the Main movie file,there may be 2 or more-wide/full screens-
Click on the main movie you desire,drag to left side of screen.Use the view screen slide bar to see the main movie you want.

Click compression settings tab,untick subpicture and tick AC3 5.1CH English only.

Click the icon with 2 arrows,pointing in different directions. This is the frame start and frame end.You'll see 2 small viewscreens.Use the arrows or slide bar to set where you want to start and finish,cutting out ending credits/ click OK.

Click backup tab. Double check settings. Since you now have less compression:
In the quality tab of the backup options screen,if this screen is grayed out if no compression is on it.If it lit up-it is being compressed,untick the box that says High Quality Adaptive Error Compensation. That enhancement will slow you down big time.I only use it with max smoothness say about 20% compression or higher.
Double check the other targets and settings,click ok and you'll be on your way.

By reducing compression,you can increase the speed of backing up a dvd. The majority of the media I do is main movie only. Most of the bonus features and extra I rarely look at on my originals. Here's a few examples of my times at a 4x burn speed:

Main PC,specs are in my signature:

30% compressed/main movie/max smoothness quality enhancement-45 mins- 1 hr.

No compression on standard DVD-5 blank-20-25 minutes.


Backup pc: 598 mhz celeron,xp,256 mbs ram:

30% compressed/main movie only/max smoothness/ 6 hrs.

No compression/main movie only= 30-45 minutes.

That backup 598 mhz,despite the lower end of the spectrum for specs, isn't much slower at the re-authored main movie only,but with the more compression and adaptive error compensation quality enhancements,that time really increases. I did one at 45% compression and max smoothness and took 12 hrs.

What are your pc specs?
