Capture problems

Hey there,

Got the ADVC100 and went to capture, got plenty of dropped frames instantly. Searched the forums and tried a few things. Got it to work without dropping any frames, well once anyways.

Any suggestions? Further articles to read? As of right now when I capture, (analog) it captures without problem for about 2 seconds and then just starts dropping frames like crazy. vipCap in VV5

Are you capturing to a seperate drive (not your system drive)? Got anything else running in the background during capture?

In general you should have a separate physical hard drive for capture. Not just a second partition, but a second physical device so that there is no contention with the system drive. It also helps if this drive is a master device on a different IDE channel than your system drive. If it is on the same IDE channel writes will be serialized between the two drive.

Next, depending on how much memory you have (or rather don’t have) Windows may be swapping to the swap file. You should probably override Windows control of the swap file and set a permanent swap file so that it can be accessed quickly. Try and unload any non esencial applications including anti-virus that might be checking the drive while your capturing.

Lastly, make sure your capture hard drive is defraged. You don’t want Windows to be searching for free space when it should be writing frames.

Those are the three biggest things. For more tweaking tips go to Videoguys.com techsupprt. In the Quick Nav bar on the left is a topic called “OS Tweaks for NLE” with a list of operating systems. Just select the operating system you're using. They are also a great place to buy hardware and software.

I am on a seperate drive, 120Gb used just for capture, 60% free space there and defragged. 1Gb memory. Nothing running in the bg other than Vegas. Heading ove tot hat link now to check them out.
