Videoredo bringing quadcore to its knees

I have a pretty high end system including an Intel Q6600 quadcore but when I do a "Save As" for videoredo it brings my entire system to a crawl due to disk I/O. Is there a way to keep videoredo from doing that?
 
Since no one on staff has responded yet, I'll offer my thoughts.
Since VRD is disk I/O bound, you need to make sure all the drives are running in Ultra-DMA mode (not PIO). You should also read from one drive and write to a second physical drive for best performance. You should check the cluster size on the drives also. 4k is default, bigger is better for video, and 512 bytes indicates a need to start over, repartition, and reformat.

With your processing power, trying to read from and write back to the same drive is going to be a real bottleneck.

Of course, there is also a setting in the "Enhanced Features" options to "Reduce CPU Priority While Saving" you could try too. I don't know if that is likely to help in your case, however.

I've tried VRD on a Quad system and it's blazing fast. Even with source and destination folders on the same machine.

Do the checks Zaphod recommended.
 
It may be your antivirus software bringing your system to its knees. I disabled norton antivirus from reading my .tivo files because it was making my file open times unreasonable.

Sounds good. I did find that my system was much more responsive when I did it to a separate disk but I will take a look at the settings.

I did notice that CPU util was around 3% but disk IO was around 100% when the system would slow down.
 
Some more ideas.

There are a number of things that can occur at fixed intervals that can upset file processing.
Superfetch/Readyboost in Vista should be turned off.
Drive Indexing: can be turned off in drive properties in Window's Explorer.
Windows Messenger Service
Auto Inset Notification: optical drives - remove disks and/or turn off all autoplay options.
AntiVirus: ? on methods.
Network Pings: ? on methods.

Other problems can include Sound card drivers (SB-Live was notorious for hogging the PCI bus) and converted drives. (a drive converted from fat32 to NTFS ends up with 512 byte clusters. A drive running in PIO mode could also cause problems. (vs DMA)

All of the above occurrences will be magnified if the authoring program is re-encoding the file (clue - takes an hour or more to complete) but the abberations can occur at many places during the process but not show up until the final steps. Eliminating most of them is a slow trial and error process and it could be something completely different.

One thing to note. I recently went from an AMD X2 4200 to the Intel Q6600 without reinstalling windows. The computer was able to be used on the X2 so I am guessing either there is a driver issue or else the drives reverted to PIO mode which I will check tonight.

With major changes such as new mb or cpu, it's (rightly) advised by ms. To start again with a fresh install of xp or vista.

The machine itself is running really well other than this one glitch which may just be the drives in the wrong mode.

Vista went through redetecting all of the hardware when it came back up (I made sure to uninstall all of the old drivers first).

One disk test you can do with VideoReDo is to run Tools>Trim and copy. This is nothing more than a simple disk copy, read/write, read/write, etc. If your system stalls during that then there's a problem with the disk sub-system.

It slowed things down a bit but not to the same crawl that it had been at even though Im doing this on my OS disk. Things are much slower but Im guessing they should be since my OS disk is now tied up doing a 4.5Gig copy although I didn't have nearly the same slowdown when I copy a 4.5GB file via explorer.

Take the Hal or system registery, there is two very good reasons. To start afresh with a new os install.

Have done the same, had problems which manifested in time. Ended up with a fresh os install, never looked back. Ok it was years ago, but ms os's are just the same. Ok vista is different, ms will still advise the same procedure.

Create a short video file, preferably standard def, of about 1 min in duration. Then open the file in VRD and resave it. On the output complete dialog screen what are (a) frames / second and (b) average bit rate.

Repeat a 2nd time and let us know the results. We can then compare with our own machines here.

Sounds good and I think I may have found something slowing my system down. My nice highspeed SATA drive is running in IDE mode because I hadn't turned the AHCI bios on on the motherboard. I will play with that tonight.

Just tried this on my Q6600, 1 min mpeg pal dvb recording,

First run;
Video output frames: 1500
Audio output frames: 2501
Processing time (secs): 1
Processed frames/sec: 1313.49
Actual Video Bitrate: 4.50 Mbps

Second run;
Video output frames: 1500
Audio output frames: 2501
Processing time (secs): 1
Processed frames/sec: 1296.46
Actual Video Bitrate: 4.50 Mbps

Those numbers look pretty good to me. Your machine may not be responsive, but its processing video very quickly. Did the BIOS change improve things?

Ah, sorry for the confusion, I'm not the original poster.
Just thought I'd put my stats here for comparison :)
 
When I added a SATA storage drive (motherboard controller) to go with my IDE drives, I had to install the RAID software even though I was not running in RAID configuration to get the speed up to normal.
