Thanks Dan – that is close, but not quite right – maybe because of the y-rotation which is also occurring?

I have a little experience with it, but not tons… what kind of info are you looking for?

I assume you mean muxing errors in DVDSP? I’ve had the same issues.
I personally really like using BitVice – it gives very nice results at relatively low bitrates – but have found that it isn’t worth using unless you have a lot of material that you need to squeeze on one disc and/or have lots of time to turn on extra features and render (overnight, usually).

As far as cost vs. performance, the 7800 is well worth it – you will see nice speed improvements in all OpenGL applications. TheQuadro is a hi-end workstation card, which is very very expensive. According to benchmarks and articles I’ve seen, it is not worth the extra $$ unless you are doing hi-end 3D work, such as Maya. Even for gaming, the quadra doesn’t really offer any significant improvements over the 7800. Here’s hoping the new Intel “mac pro’s” offer SLI!

Thanks johan, but that didn’t work – still distorted…
After much fussing around, I came up with these settings that seem to work:
In encoder (MPEG4) I chose 16:9
In resize, I chose custom, then set the aspect to 16:9 – I could then input anything I wanted for the width and it fills in the height for me.
also in resize, I set pixel aspect to “assume 16:9”This works very well!
Thanks for your input, and I hope this can help someone else down the line!

BitVice can be very fast or very slow…
To explain – it has some very impressive features, especially the Dynamic Video Noise Cancelling – which allow for very high quality at somewhat low bitrates. It will allow you to get 2 hours or more on a DVD-R without much sacrifice in quality. But what you DO sacrifice is encoding time. The DVNC looks really great, but it take a LOOOONNNGG time to process. It is up to you whether it is worth the tradeoff.
Also, the FIRST pass runs in realtime (or near realtime) – even with DVNC turned on. It is the second pass that slows you down. Without any special features turned on, it encodes pretty fast (comparable to compressor) with very good quality. But with the features turned on, you can get AWESOME results, but at the cost of encoding time.
Personally, I’d go with BitVice, but don’t be fooled by the real time thing – at least not yet!

I’m pretty sure the Newtek VT is a PCI based system – and I think for PC… the MacBook does not have PCI slots, being a laptop.
I don’t think you’re going to be able to get both the alpha (matte) and the graphic out at the same time (ie. to go live with). Even in the full-sized trucks (for live sports TV – which I do sometimes) we get tapes with the graphics, then the matte (a black and white video of the alpha) one after another – which we then have to feed to the TD one at a time to put in the ‘board’ (switcher) and do his magic with. The switcher uses the B&W matte to punch out the alpha for the graphics. Occasionally, we’ll feed them both to the “elvis” (LSM) and then have the Elvis output both to the TD at one time, but that’s an extra step, so most don’t do it that way. Good luck,

I have it and it works great! I think the listing mentioned above means x700 THROUGH 850. It allows all OpenGL features except for Motion Blur and Antialiasing (which means it allows All Blending Modes, Adjustment Layers, Track Mattes, Accelerated Effects, Lights and Shadows). Pretty fast too.

OK – thanks for the info…
But it seems like a fault in the application – not the machine. An app that just plays movies shouldn’t take that much CPU should it? Especially if it is designed so that you can follow along with the training. I guess it has to do with the HD video, but still – it makes following along with certain sections pretty much impossible.
Thanks for the replies.
