PP CS4 Dropping Frames Randomly on Capture
Hi,
I’ve newely installed CS4 on a brand new computer. This computer isn’t connected to the net so I don’t have any firewalls or anti-viruses running. Its a Quad Core 2.5Ghz, 7Gb Ram and 1Gb Geforce 9800 Graphics. Sometimes when I’m capturing into Premiere Pro CS4 it starts dropping frames and you get the classic green or yellow squares on your footage. It usually happens after about half an hour of continuous capture, however sometime its happens straight away and other times not at all. Sometimes it’ll drop a couple and other times everyframe wont play back and their just a mess. It can happen when scrolling through the tapes to find in and outs too, not just when writing to disk. Its not the camera head as the tape is playing fine on the LCD. It fixes itself when I restart the computer but I need to capture some stuff from a live cam soon and I dont want this happening then.
Does anyone know what could be causing it? I was thinking maybe a dodgy firewire port, would that do this and fix on restart?
Thanks

Does Premiere tell you that you are dropping frames? Your description sounds more like corrupted data. If the LCD on the camera does not show anything unusual, then the firewire cable/card and camera’s 1394 controller are suspect as well as the PCI slot.

Yeh Premiere does say its dropping frames when its doing it while capturing. The Camera and cable works fine when Capturing to my old CS3 on another computer. The Firewire socket is built into the motherboard, I was thinking maybe buying a PCI firewire board might fix it?

Describe your hard drive configuration…size/free space and capture drive.

Theres one 750GB HDD in the computer thats partitioned into two 375GB sections that show up as two seperate drives. All the programs are installed on one part and I’m capturing to the other part. The part I’m capturing to has about 200GB free space, most of the space is used by single large video files that have been on there all the time, so I shouldnt be filling in fragmented space. They are NTFS Files system running from Windows 7 64 Bit. Not sure on the RPM, how would I find that out?
This afternoon I captured about an two and half hours continuously (changed a tape in the middle) without any problems, but I had to restart my machine before starting the first tape because it wouldnt even play it properly when I first tried. So random!!

A partitioned drive does not help capturing video. The system drive is often busy doing things that distract capturing, like checking for updates or Page file shuffling. While a one drive system can capture fine as you have found out, most here could not live with it.
For $99 you can plug in a new 1TB SATA drive. -
Cool, I’ll get a new dedicated HDD then see if that helps. Although it does it when playing through the tape aswell as capturing, so is it still using the HDD then?

[Phil Thomas] “Although it does it when playing through the tape”
Does what? Are you previewing on the cam’s LCD and seeing artifacts? OR are you seeing artifacts while previewing in the Capture window while just playing the tape??
-
I’m seeing artifacts while previewing the footage within the capture window while just playing the tape. But I can simultaneously look at the cams LCD and there are no artifacts. Sometimes its just a few green squares on one frame every now and again. Sometimes the whole footage wont play and its just artifacts.
-
You should see no artifacts anywhere, but it does seem to sound like more artifacts are being produced in the hardware pipe to Premiere’s capture window. You need to do an elimination process to find the culprit. Begin by connecting your camera to a different PC to eliminate or convict the camera. If no artifacts are seen, then try a different cable/card on your PC.

I found this thread while searching for a solution to my dropped frames and other issues while capturing, editing and rendering video in Premiere.
Currently, I only have a single hard drive, and the solution of purchasing another hard drive that would be dedicated to digital video appeals to me… but I know very little about hardware!
You briefly mentioned the 1 TB SATA drive, but I am hoping I will be able to get some more information/guidance, so that I can go out and buy with some confidence that I know what I need. Can someone here please help me?
