Dropped frames no matter what

[clothesburner626]

Processor = Intel 2.6 Ghz with Hyperthreading and 800 FSB
MBO = Asus P4C800-E Deluxe
RAM = 1 GB DDR 400
Primary Master = 80GB Maxtor 8mb Cache
Secondary Master = 80GB Maxtor 8mb Cache
RAID = (2) Western Digital Raptor 10,000 RPM Drives


Hard drive fully defragmented, no programs running in the background... I don't get it. WTF? Dropped frames occurs about an hour into an hour and a half recording. For the first hour, it'll say zero dropped frames, then, towards the end, it'll say something ridiculous like 746 dropped frames. What am I doing wrong? It's even worse when I capture to the RAID drive which as you can see above, are 10,000 RPM raptors.

It may not be a system problem. It's possible the video source is losing sync and causing the dropped frames. A TBC might help.

Sounds like you're running out of hard drive space. You may also want to remove any unused registies as well. Run only the programs you need during capturing, turn off the IE, because surfing's not allowed.

What's A TBC?

[Tommyknocker]

Time-Based Corrector. A circuit on a computer card or inside a box that cleans up video signals.

I'm using a Canopus ADVC 100. Still need a TBC?

[Tommyknocker]

I would follow the advice on my first post. Since the first hour you had no problems, unless the tape became degraded after a certain, you can hold off on getting the TBC for a little while. If you have a video camera with pass through, you may not even need one.

I don't have that problem with mine. Your hardware is 3x more than you need on every spec.

Did you answer the disk space issue? Frame drops happen as the disk seeks space.

What is the source of the video?

Sorry. What's the IE? Internet Explorer? This computer is not connected to the internet nor will it ever see the internet.

Also, make sure you are capturing to a separate partition from windows. Better yet a separate drive and IDE channel.

This keeps windows from taking priority on the capture drive. If you do that you will have no problems with IE.

To make your system work better for video editing, get a third drive for windows and keep the RAID separate.

Also make sure all your buffers and scratch files go to the RAID, not the windows partition.

I'm reformatting an 80GB Maxtor drive with 8mb cache as we speak. The drive will be my secondary drive, 100% seperate from Windows. Source of video = JVC Video/DVD Player.

You shouldn't "need" a TBC except for making best quality VHS-SVHS dubs.

The ADVC works well for VHS dubs and keeps audio in sync.

I'm getting clicks and pops in my audio... is that common with the ADVC or when pulling footage off of video tapes in general?

[edDV]

Are the clicks and pops random or do they match edit points or some other event?

Random... not apparent when video tape is played through vcr, but when played through vcr into canopus, out of canopus into computer, clicks and pops throughout. M-audio delta 1010 soundcard, built in sound card disabled. Your thoughts?

[edDV]

I've never experienced that. I' m trying to think of possible causes.

Try this if you have a DV camcorder. Record from the Canopus into the camcorder via IEEE-1394 and see if the pops are there. If not, the problem is in the computer.

I use to drop frames like you until I purchased a second HD and began transferring the video to the HD that windows isnt on. Now I never drop frames.

Try using a different source and see if you still drop frames?

[FulciLives]

My guess is that the RAID setup has something to do with your dropped frames problem.

The audio problem is rather odd though

I know this is going to sound counter-intuitive, but turn off Hyperthreading. Try it if you've run out of ideas.
