Dropped Frame Issue
Immediately after installing Premier 6.0 (and the 6.01 update), I went to capture my first segment of video. Boy was I disappointed when I dropped frames all over the place…. I searched around and found that I actually had 3-4 things that could easily be the culprit. As a Windows user, here is what I would suggest doing to stop the dropping of frames: Hard Drive Issues: Issue number one: If at all possible, you should be using a second hard drive to capture your audio and video clips. If you’re capturing to the same hard drive as the operating system or Premier 6.0, that hard drive has other jobs to do besides capturing and writing video to itself. When it goes to do those other jobs, it’s going to drop frames. Even if you have a second hard drive, it does not mean you’ve setup Premier to capture and write to that second hard drive. Here’s how to set Premier to capture to your second hard drive: 1. Go to “Edit” in the menu bar, select “Preferences” and then select “Scratch Disk and Device Control”. In the resulting dialog box, make sure the top drop-down list is set to “Scratch Disks and Device Control”. Then, set “Capture Movies”, “Video Previews” and “Audio Previews” to a file/location on your second hard drive. Now you’ve set Premier to write to your second hard drive! Issue number two: Make sure your hard drives are defragmented. If they’re not, your hard drive’s write needle has to jump around all over the place from non-contiguous write space to non-contiguous write space. To defragment a drive, double click on “My Computer”. Right click on the Drive that you want to defragment and select “Properties”. Select the “Tools” tab and then click “Defragment Now”. This process stores existing data on the hard drive into one contiguous space with no gaps. Issue number three: THIS IS IMPORTANT - Make sure your audio/video storage hard drive is set to “DMA” - doing so increases the disk’s access speed - due to some incompatibility issues with older drives, this is defaulted to off. To enable DMA, right click on your “My Computer” icon and select properties. Choose the “Device Manager Tab” and then double click on the “Disk Drives” listing. For the hard drive that you are capturing video to, double click it (for example, “Generic IDE Disk Type 2”). Now select the “Settings” tab. Make sure that the DMA check box is selected. Click OK. You’ve now turned on DMA. Note - the above directions apply to Windows 9.x and Windows ME. If you’re using an NT-based system, I’m not sure how to do this. Issue number four: I’ve read on this forum that, if your storage drive is more than half full, performance starts to degrade. I’m not sure how much this helps or hurts, but I thought I’d pass it along. Issue Number five: If you find you’re dropping frames at the beginning of your first capture, after starting up, or early in any movie captures - Check your “Power Options” - found in your control panel. Set “Turn off Hard Disks” to “Never”. If your hard drive, where you store video, spins down or powers off, it takes time to spin back up to capture video. You will drop frames early on. I’ve found that you can get the drive to spin-up to speed or turn on by accessing it prior to video capture (go to your file manager and select your storage drive. It will automatically spin up to speed (you can actually hear it turn on and spin up if it was off). Hardware and Software Driver updates: Make sure you have the latest drivers for your Firewire card, ATA controller (or other hard drive controller), Direct X drivers (PC only), Video card drivers, BIOS, etc, etc. Some tips that I found while searching for ways to solve my dropped frames problem” First: Make sure you have the latest Direct X Drivers. Go to: http://www.microsoft.com/directx/homeuser/downloads/default.asp download and install the latest. Second: Microsoft has a Direct X “video capture update” that can be found on the same page as the Direct X Drivers. Third: If you have an Intel-based Ultra ATA drive, install their updated drivers. Go to: http://support.intel.com/support/chipsets/storagedrivers/ultraATA/ and select “Download the Ultra ATA Driver”. Firewire cable/ Firewire Card Install Issues: Issue Number One: IRQ conflict is probably #1. Capture cards don't want to share their IRQ. If they do share an IRQ, it can cause problems. To check, right click on “My Computer” and select “Properties”. Select the “Device Manager Tab” and then click on “Computer”. Select “Properties” and you will see a list of IRQs, and the resource that is using each IRQ. If you’re sharing an IRQ with a device that is constantly active (a video card for example) this can cause problems. See your Firewire’s manufacturer’s instructions for details on solving IRQ conflicts. Issue Number two. Your Firewire cable could be the culprit. If you can switch cables with a friend or a store, try it. Other Suggestions: Turn off the "during capture, preview video and audio on desktop" setting. Go to project > project settings > capture. Click the DV settings button and uncheck both the boxes under the "during capture" section.
