Ali,
Thanks for your response. I tried changing those CODEC options in Vegas with no luck.
You mention “capturing”. Do you mean use the taped version of the event rather than that recorded to HDD by DV Rack HD, or is there a way to use the Vegas Capture utility to import the DV Rack created m2t?

Correct, there is one HDV (M2T) on the timeline. The HDV audio is 48 kHz. Whether I mute the audio or video track, the playback preview frame rate never exceeds 10m fps when Best(full) is selected.
Going to intermediates is a possibility, but it seems like a step backward to Vegas 6 in terms of my workflow. It would like to determine what the bootleneck is when using the Windows Secondary Display as an external preview monitor.

John (Frey),
Do you really think RAID is necessary for HDV content (MPEG2-TS), where the stream is limited to 25 Mbps? (some most modern 7200 RPM, SATA, drives are typically more than adequate to handle this data rate – as I understand)

Some additional experimentation indicates that if I do NOT select the “Preview on external monitor” button in the Video Preview, but rather drag the preview window to the secondary monitor and resize to fill screen of the secondary monitor, then I maintain 29.97 fps at Best (Full). Once I enable “Preview on external monitor” button in the Video Preview (with the Video Preview window docked on the primary monitor) the frame rate drops to 9 fps.
Could there be a Windows Secondary Display (Options=>Preferences=>Preview device tab) setting causing this decreased frame rate?
p.s., I did discover the audio properties of the project were 44 kHz and not 48 kHz, and hence did not match the HDV source. Although the frame rate playback improvement that resulted from matching the this project parameter to the source appears small (e.g., 1 fps).

JR,
Thanks for your “data point”. So my system could be doing better, which means more investigation is needed on my part.
The HDV is an m2t file straight off my Sony HDR-HC1, which sounds like it is equivalent to what your baseline used.
I might try pinging Sony Tech Support on this one.

Hi John,
Great advice, which I greatly appreciate as a newbie to DYI system building. The last thing I want is to be spending lots of time casing down troubles. An Intel-in-Intel approach does make a lot of sense from this perspective.
What about overclocking with Intel motherboards? Are they overclocking friendly, should I wish to dip my toe into the overclocking waters?
Finely, any informed speculation regarding possible 64-bit Vegas benefits of getting a (P45-based) motherboard that can grow up to 16 MB of RAM?
Thanks!

Steve,
Yes there are tons of post on this general topic, but none (that I could find) that specifically speak to my questions.
So again, input sought from **recent** system builders (as the technology changes least every 6 months) and specifically on choosing a Motherboard (P45-based vs x38/x48 based). Any other tips/recommendations for a first time system builder are welcome (I plan on a Quad Core Intel CPU, two 500 GB HDD, and 8 GB memory)
–Thanks

Thanks Gary. That did the trick!

Here are some additional details regarding the QuickTime formatted (H.264/AVC encoded media) file :
The “Movie Info” provided by the QuickTime 7.0 Player for the QuickTime formatted media in question is:
Format: AAC, Stereo (LR), 44.100 kHZ, H.264, 1264×720, Millions
Movie FPS: 24.57In Explorer tab within Vegas it correctly indicates the audio tack properties, but the Video states “stream attibutes could not be determined”.
Here’s a URL to the file. Click on the 720p button to download the clip, should anyone care to look at this directly.
https://www.apple.com/quicktime/guide/hd/bbc-andes.html
Again, I know the material is copyrighted. I’m just trying to understand the “in’s and out’s” of working with HD media (in this case QuickTime file formats) in Vegas v6. I’m never done much with QuickTime before.
Thanks!
