Your computer doesn’t have an RS-232 port? I know some of the newer motherboards don’t have an external 9-pin anymore, but in that case most have an internal header that could be used with an appropriate adaptor. There are also RS-232 accessory cards, and probably USB to RS-232 converters.
You really want to capture from Beta with a RS-232 to RS-422 adaptor cable plugged into the Beta 9-pin remote, and using serial device control in Premiere. This will capture the beta tape’s original timecode with your clips.
Yes there is timecode in the ancient world of analog. All Betacam tapes have timecode.

Nice system. I just built a similar system with the 5460 processors and an Axio LE card. The speed that this thing cranks out Blu-Ray DVDs makes one giddy.
32-bit Windows kinda maxes out on 4 GB, so I think you are wasting your money on 6 GB unless you intend to upgrade to 64-bit in the near future.

Is this just for Macs? I don’t see 3.1.1 on my Windows machine.

Composite video (with 100% white levels) is 1 volt peak to peak, including sync. Sync goes from 0 volts (blanking level) to negative .3 volts. The actual video signal (including blanking) goes from 0 volts to positive .7 volts. Frequently this is expressed as IRE units, where blanking is zero, black is 7, white is 100, and sync is -40. So there are 140 IRE units in a 1 volt peak to peak composite video signal.
So you are correct. Adobe has gotten it wrong. They are assigning 0 volts to the sync tip (the correct value is -.3 volts) and black to .3 volts (the correct value is .05 volts – 7 ire units above blanking, which is 0 volts)
Perhaps they should stick to IRE units and forget about voltage.

That’s too bad, Steven. I was loking forward to your review, especially from the perspective of a long time Cineform advocate.
I have found that the RTX2 craves a quad core (or even dual quad Xeons). The export and render speed is quite astounding. It’s great to see eight cores going full tilt in task manager as your HD timeline (native HDV) downconverts and encodes to an SD DVD at around 5x real time. By the way, a great line of cases for the RTX2 are the InWin S-series (single CPU systems). Extremely quiet (and they will accept a full size card).
-
I-frame does encode each frame seperately. It’s IPB (or long GOP) that compresses over a series of frames; and yes, that can bog down in AE or Photoshop. Best to convert that material to a frame-based codec (which includes I-frame).
-
AE is not crazy about long GOP MPEG (HDV), so typically I would convert HDV source material destined for AE to a frame based codec, like Matrox I-frame MPEG, or DVCPRO HD. You could also do uncompressed or TGA/TIF/BMP sequences. I imagine it’s the same story with Particle Illusion.
The great thing about the Matrox effects working in both Premiere and AE is that you can import (copy and paste) from one to the other without losing filters. For example, I frequently use the Matrox DVE and Chroma Key in PPro; import into AE with effects intact; then replace keyer filter with Keylight (which requires a heck of a lot more tweaking, but ultimately will pull a better key). I have real time effects control for setting things like mask, size and positioning in PPro, and I dont have to reinvent the wheel when I bring the material into AE.

A couple of nice things about the Matrox RTX2:
It plays multiple streams of native HDV. No transcoding means the highest quality and no conversion during capture. File sizes are small, and file management is simplified. Plus you can see your video in the capture window.
You get a comprehensive set of real time effects that work in After Effects as well. The chroma key is superb.
A DVI output allows you to use a 1920×1200 computer monitor (#2 monitor) to monitor full screen (with no A/D conversion – super quality).
Renders and exports are greatly accelerated by the Matrox hardware.
You get analog SD and HD I/O.

[jiri vrozina] “my old 7 year Pana 910 has got better SD picture then HD picture from Sony XDCAM HD …..explain why.”
HD cameras suffer somewhat in SD mode because the image enhancement they apply is out of the SD bandwidth. SD cameras, of course, apply in-band enhancement, and tend to look “crisper” in SD. That’s why I’m not selling my Betacam yet.
Perhaps some high-end HD cameras are capable of applying in-band enhancement in SD mode, but none I’ve seen – including the 330, I believe.

If you want a higher resolution picture, go for the V1U. The HVX200 has a limiting resolution of only 500 lines. The V1U is around 800 lines. The upcoming EX1 is over 1000 lines. In a direct A-B comparison, there is significantly more detail in the V1U images as compared to the HVX200.
