Ok, people please listen to me

+I don't want to know the minimum ram i just need to know how many Megabytes per second need to be written to harddrive for the DV format


+It still drops frames (usually about 300 out of 1000 frames) even when i have it set up to not show a preview window or anything while capturing



Thankyou, please just answer that :P hehehe

Megabytes per second is around 3.7. One thing I would check: Is DMA active on both drives? If not, make sure it becomes active!

I only need 3.7 megabytes per second? Ok so its not the harddrives then if thats true...

DMA is enabled but its only transfer mode is at : DMA ULTRA TRANSFER 2

Any ideas? Because in the tutorial it shows it being DMA ULTRA TRANSFER5
not 2...


Hmm just making sure you guys get this not being an asshole but...
DMA ULTRA TRANSFER 2
DMA ULTRA TRANSFER 2
DMA ULTRA TRANSFER 2
DMA ULTRA TRANSFER 2

Just making sure you get it, because people dont seem to be reading hehe except for a select few

There's definitely something in there slowing down the drives and/or eating CPU time. Do you have any USB devices connected? Try disconnecting those and see what happens.

My modem is USB, and my mouse is USB, i disconnected modem and tried it:I proceeded to drop 512 out of 623 frames...

Ok i tried exporting again, and now that i plugged my Cable modem back in im back to normal, losing about 50 out of 400 frames

Back again. Just out of curiousity, do you have Windows Moviemaker still onboard? Can you try capturing with that app? Darryl

Yup, and it lags like a mofo as well

This is the information you left for everybody to go on.

Ok, In order toexport to pc, I recently bought the following items: WINDOWSXP pro, 80gb 7200rpm 8mb cache hd, Firewire port

My camera is a canon zr60

However, in vegas when i capture it drops about half of all the frames, which is very unsettling :()

SPECS
1.8ghz p4
256mb sdram
gforce 2 mx 32mb

Just what kind of computer is this? Your video card is a Gforce 2 MX 32mb. I thought those were ancient. Is your computer a Dell or some other 'already put together for you' type of computer? You give us minimal information and then get mad because your questions can't be answered. We're all spending a lot of time trying to help you and your acting like were all to dumb to understand you. If all your stuff is brand new, give yourself a couple of months to work all the bugs out before you go crazy wondering why things don't work. I just barely noticed your video card, because it was written at the very bottom of your 2nd post. I don't even know about that card, I thought I heard that the G Force 2s were from a few years ago. Again, I'm just guessing, but I am trying to help you.

OK, 2 capture apps are producing the same result and two hardrives are as well (os C & ext E). What's left? The camera, the cable and connections, and the computer hardware.

What's the pc (get specific)? Have you tried another camera? Have you cleaned the heads lately? Have you tried another tape? Have you tried another cable? Can you capture this camera and tape on another computer? Darryl

When I had a problem with LOTS of dropped frames and had turned off antivirus and all the other backgrounds, and it STILL didn't solve the problem - what finally did was to resize my preview window to the smallest and I had no more problem.
I found this out by accident, but have since learned that it is a known solution in some instances.

* Yes I can export with camera to a different pc, that was awhile ago though (maybe 3 months ago, havn't really used it much since)
However, it wasn't with this cable nor was it with this firewire board...

That leaves the option of that its either the firewire or the firewire chipset, because when i try to preview it on the screen (Playing off the camera, not capturing) it still drops frames

-----
Yes, I dont even HAVE the preview window open, so that wouldnt help ...

Another thing i just thought of, cou8ld it be slowdown caused by ram?
My specific specs... i am not sure what you mean by this

So it had to be something external, the camera perhaps? Hmm ... nope, i went over to a friends and tried on his mac, perfect

That leaves only the cable and the firewire board

I inspeccted the board and the little yellow lines that connect it into the port arnt all the way in, like i think they should be... correct?

That means theres not enough spacee in my case (motherboard for p4 takes up 85% of the case, to give you an idea of size)

If that is the case, then I have to buy a bigger case... god

I think you're closing in on it. If you can, take your external drive to a friend with a PC (not mac) and windows movie maker, capture your files and bring it back and get to work on your project. In the meantime, sounds like a hardware issue to me. Get some pro advice. Good luck. Darryl

Do you have both hard drives connected to the same IDE channel? If so, any application that accesses your Operating System will interrupt data transfers to either drive.

The reason for this is that the PCI bus can only "talk" to one device on a given IDE channel at a time. If your OS ("C") drive is configured as master on IDE 1 and your data drive is configured as slave on IDE1 it doesn't matter which drive you are capturing to. Any running process that accesses the OS will interrupt data flow to either drive.

Try this. Disable "Autoplay" in Windows XP. My old machine was a 450 MHZ P3 with 256 M ram and one 40 M hard drive. I was able to successfully capture and Print to Tape once Autoplay was disabled.

If that doesn't help, connect your data drive as slave on IDE 2 (your CD drive should already by connected as master on this channel).

While you're at it, make sure that your IDE cables are the 80 conductor variety. Using 40 conductor cables on fast hard drives will generally work but may cause the need for substantial error correction operations. These error corrections will interrupt a DV data stream.

Figured it out, the damn firewire cable was faulty, god... just my luck too

Awwwlllll Right! Way to stick with it. Congrats, Darryl
