Capture to 2nd Hard Disk ("D:\\" disk) is Choppy

Post by mrf »

Capture to Primary "C:\\" is fine but I only have 15 G left there. Capture to Storage disk "D:\\" yeilds choppy audio and video. I have double checked all capture settings and done hours of research, trial and error - mostly error. Help. Thanks.

Hi MRF,

Several users have multiple HDD, and capture to a secondary drive without problems. In fact should be smoother, because the heads on a single drive is working less. Instead of reading and writing, one drive reads while the secondary (capture drive) writes.

How are you capturing, Firewire (iLink iEEE1394, or USB)? What format are you capturing, DV-AVI type 1 or type2, MPEG1 or 2, other AVI such as Xvid, DivX?

What applications are running in the background while capturing? Are you experiencing dropped frames while capturing? Go to the File Menu>Preferences, on the Capture Tab, check Show Drop Frame Information.

When you say it yeilds choppy audio and video, how are you viewing the video files, in VS9 in Project Mode, or clip mode? Is the choppy product a rendered file, ie; a DVD-Compliant file, or some other format such as WMV, MOV, MPEG1?

I know that's not much help right now, but the more we know about your process/workflow, your project and video properties the quicker we will be able to find a solution..

You call drive D:\ a storage drive. Do you mean it is an internal or external drive? If external, how is it connected -- Firewire or USB? And if it is USB, is it USB 1.0 or 2.0? (Latter probably required to maintain speed/volume of high quality video transfer...)

IF you are talking about an internal IDE drive and IF you are capturing correctly eg. by firewire, then I had a similar problem a few months ago where the computer appeared to be otherwise fine.
It had the same video capture problems you have described.

In my case the problem was that an IDE cable connection had become loose. visually the connection looked intact but by simply giving it a good press with my thumbs the problem was cured.

Tricky!

I had the same problem (internal IDE) drive and firewire. It drops a frame or two per second. I never solved it, so I just have to capture to C: then move the file to my D: drive where I keep all my video files.

You could try stopping all other unnecessary processes (broadband, virus checker etc).

Let us know how you solve it ! :D

Not exactly the same, but I had performance problems in analog capture to AVI until I changed my swapfile from the target disk (like your D:) to the main disk (your C:).
IDE often defaults to drive 0 for hard disks and drive 1 for DVD players. Then your capture and Windows fight for the controller's attention.

IF you have IDE interface and your swapfile to D: you could try changing the swap file to C:, it shouldn't be 15GB.
Your existing cable length permitting, you could have your D: as master on drive 1 and your DVD(s) as slave(s). Generally helps performance of the whole computer I/O subsystem.

I don't know the relevance with SATA disks, but it is irrelevant with SCSI.
