Twice Speed Playback


guido_67

Question

I am also a newbie, but have been using Roxio products in one form or another since version 5. I recently purchased a new DVD burner that had the Roxio EMC 7 software bundled with it. I love the software, and have already (in less than a week) become proficient in using the audio side of it. My problem is:

 

I have a Canon DV camcorder and want to generate DVDs from the tapes. Sounds easy. I read through the users information and help screen data, then started on my way. I performed the capture using the mpg setting to keep file size down. However, the files that were created play back on my machine, as well as on the resulting DVDs, at twice the "normal" speed. Is there a simple button I'm missing in the setup, or should I just be forgoing the mpg capture and using the avi capture route instead?

 

Any help would be greatly appreciated.

Capturing to avi format will give better quality in the end although you will create with much larger files initially.

Could you list your computer specs, especially your video/capture card and your DirectX version? Your twice normal speed problem could be related to the video card and/or your version of DirectX

Walt,

 

Thanks for the quick reply. Some of the quick & dirty on the computer:

Dell Dimension XPS T450 - Intel Pentium 3 450 mHz

768 MB RAM

Windows XP - SP2

 

The firewire card installed is an Adaptec FireConnect 4300

 

As far as I can tell, viewing the Directx.log file in the Windows directory, the version in the registry was listed as 4.09.00.0904.

 

Hope this helps.

 

Steve

All other things being equal, if I have a machine with a P4 running at 1.6 MHz or better, this problem should go away? I hope to have resolved the CPU issue, as I have purchased a P4 2.6 MHz machine earlier today. Given that the hard disks in my current machine are adequate in size, I'm basically going to transfer all of the hardware (master and slave HDD, master and slave DVD writer and CD ROM drives, fire wire, ethernet card, etc.) over to the faster machine and scrap the P3.

 

The Pentium 4 will be able to do the encoding and decoding necessary for mpeg2. The slower the P4, the more time you're going to spend waiting for the video to encode. With a 1.6 MHz, you'll probably have time for a round of golf while the machine is encoding.

 

Speed also matters when it comes to hard disks and the internal cables in the computer. You're going to have to do some research to make certain that everything will work properly in what you're building.

That Pentium 3 does not meet the minimum specs for the software. In short, it isn't going to work, even if you get the capture to the hard drive.

Bruce,

 

As the software came bundled, there was no minimum system requirements information posted on the outside of the box, nor did any information come up in a splash screen during install. My bad for putting the software on an older machine. The part that still doesn't sit with me is that I have completed small (2-3 minute) captures in DV/avi formats that worked fine. It's only the mpg captures that are playing at twice times speed. I was also able to capture a single 11 gig (57 minutes or so) manual capture avi on this machine. It seems like the software is working OK, that's why I figured I had a configuration setting messed up somewhere because it's only balling up on the mpg capture.

Its too bad that not all the requirements are listed on the software boxes.

This is the minimum requirement for real-time MPEG-2 capture and burning: 1.6 GHz Intel® Pentium 4 or equivalent AVI capture propably works since there is not much compression going on during capture
