“Delayed write failure” might indicate that one of the drives is failing. Do they have external attached storage like USB or firewire drives? Often delayed write failures happen when USB or Firewire drives are improperly removed. Might be that a drive is spinning down unexpectantly due to failure.
Might want to do a little listen to see if you can hear any clicking or wind up/down noises from any of the drives.
You might really advise this client to back up anything important on this system, then run XP’s error checking or some other diagnostic utility on the drives.Erik

All of the above?
Though I would say if you could only upgrade one…go for the CPU. The more horsepower under the hood, the quicker your renders are going to be. Furthermore, if your motherboard supports multi-core processors, you can purchase apps like GridIron’s Nucleo that can speed up renders and previews dramatically.AE 7 can tap into your graphics card’s graphics processor (GPU) to speed up some rendering, you’ll need a graphics card that is supported though.
Adding more memory can help you load more frames at higher quality for RAM previews.Erik

Thanks Andrew….I just ordered it…

Yeah…some people just don’t understand that just importing it into Illustrator and saving it doesn’t make it vector without doing some work…

March 13, 2007 at 1:22 pm in reply to: where can i learn more about the tricks to keying, compositing and gradingI’d second Kramer’s DVD, very helpful since it is step by step tutorials.
Some books worth buying on the subject… “Digital Compositing for Film and Video” by Steve Wright; “After Effects Studio Techniques” by Mark Christiansen (there is a AE 6.5 and a 7.0 version) covers some good keying techniques. “Color Correction for Digital Video” by Steve Hullfish and Jaime Fowler, getting kind of dated now but the concepts are still the same. I can’t speak highly enough about the Trish & Chris Meyer books “Creating Motion Graphics with After Effects” vol. 1&2. Vol 2 covers more advanced techniques including keying.Erik

Our re-seller supposedly attempted to do it because of our interest and couldn’t get it to work. Based on the disasters that occur when deviating even a little bit from the specific requirements (say updating your Quicktime version or graphics driver) of Avid’s more entry level products, like Xpress, it’s no wonder they have such strict requirements for their flagship products.

“Creating Motion Graphics with After Effects, Vol. 2” by Trish & Chris Meyer has an entire chapter devoted to working with illustrator…in depth explanations on importing, continuous rasterization, collapsing transformations, etc… as well as example projects, files and tips. Both volumes are an invaluable resource.

As far as I know, Adrenalines are only available from an authorized reseller who will only configure the hardware with the qualified HP hardware. When we bought our adrenaline we specifically asked to see if we could get it on Dell hardware. They told us that (and I’m not sure if this is true or not) that the software had “hooks” in it that looked for specific characteristics of the system and would not run unless specific qualified hardware was found. I’ve also heard that the HP workstations have a segmented PCI bus that the Dell hardware does not…Why Dell hasn’t done something similar in order to enter that market is beyond me…

Try exporting with a “straight” alpha instead of the default “premultiplied” and turn the field renderer on set to lower field first.
If you are using an Avid NLE make sure that your import settings are set to invert alpha and lower field first.Erik
