Perrone, if you click option #1, the download file is called iTunesSetup.exe.
If you click option #2, the download file is called QuickTimeInstaller.exe.

Perrone Ford February 6th, 2009 12:36 PM

Fixed.

That was disturbing because I tried to be sure to download the non-itunes version the first time.

I think the answer has to be an irrational number, because it can't be done.

Or, looked at another way, as many vegas editors as you have is not enough, because you also need a magician.

Workflow as follows:
Click on a credible download link.
(then the magic happens)
Install quicktime.

PS. these darn computers really are a pain in the a*# sometimes, I'm looking for some magic as we speak...

Ok, I finally got the latest QT downloaded from a Windows machine, and then on here I saw Perrone's link! Anyway, uninstalled the old QT, installed the new QT, installed the NDxHD codec and restarted my machine. This time when exporting a 1 minute test area from the Vegas timeline, I see QT as an option (no warning this time) and within that, the avid DNxHD codec is available. Great. So I was able to make some tests. I thought some of the quality options of this codec might be a good choice for me to use for colour correction work, and I don't need to be able to play a file like that at full speed. But could I use the lower datarate as an alternative to native HDV editing? Here are my results:

1920 x 1080p25, DNxHD 36, 8-bit (file size = 280 MB for 1 minute) does not play full speed.
1280 x 720p25, DNxHD 60, 8-bit (file size = 444 MB for 1 minute) does not play full speed.

It's a shame the 1280 x 720 option is at 60 Mbps and not 36 Mbps, and actually makes a bigger file than the 1080p version. My old computer (3.0 Ghz Pentium 4, 2 GB RAM, 2x SATA1 drives, 256 MB onboard RAM graphics card) can play full speed m2t files for native HDV editing (25 Mbps). So there is not such a need for me to edit with the DNxHD codec, though if someone has any ideas about how I can change the settings to allow my modest machine to edit with this codec, I would like to know how.

Some curious behaviour I noticed with the codec dialogue box - just me or someone else get this? - which made it less easy to use:

The dialogue springs up slightly off the top of the screen (every time), so I have to drag it down. The dialogue is strangely too short, hiding most of the bottom drop-down field box to choose the particular DNxHD details of the codec you want. Luckily, clicking the very bottom of the barely visible field box enables it to drop down, so I was able to make choices. The ok button looks "rolled up" and only fully reveals itself when you hover the mouse over it so you can confirm your choices before returning to the Vegas codec dialogue again.

LOL,

Forgot to warn you about the dialog box. Yea, it's a bug but does not affect performance. Oddly, it works fine on the Mac. A number of people have complained so I suspect it will probably be fixed in an update. But hey, it's free, I wasn't about to complain.

It is too bad about the 720p not offering a 36Mbps option. That would really be helpful, but I think the codec was really aimed at filmmakers (and I mean celluloid film) so they'd be going to 1080 and not 720 anyway.

Do take note on how I use the codec on *modest* hardware. I don't try to cut with it and get full data rate. I master with it, I color with it, but do NOT try to cut with it. It's not the codec per se. It's the quicktime container in Vegas. ANY quicktime codec simply doesn't cut well. This is why I work with the proxy files. I can cut just fine with a quarter sized file just fine in about any codec, but tend to use the Blackmagic codecs because it is one of the few than can move between Vegas 8.0c and 8.1. On hot hardware, cutting with it is fine. Or cutting with it knowing you'll need to pre-render or render to RAM on more modest hardware is fine. Just don't expect to cut 1080p at full speed on hardware that's 2 generations old.

But anyway, I'm glad you have access to the codec now. A free multi-platform Pro-ResHQ as it were, with a proxy size. If you had a modern machine, I suspect you could cut just fine with that.

Cheers.

Perrone -- thanks for your help with using this codec. I thought editing with it would be beyond my old machine, so thanks for the confirmation. This codec will be useful for colour correction work. Take up less space than using sequence frames, and I can't afford an above-8-bit square-pixel version of CineForm anyway, so this fills a niche for me.

From the Vegas timeline rendering 1 minute on my machine takes 7 mins 45 secs (for the 10980p/25 36 mbps option). Which utility do you use to transcode to DNxHD? Is it noticeably faster?

Thanks.

On the ftp site, go to the avid folder. You'll see an xdcam_to_avid folder. Utility is there, and yes, it's faster than rendering on the timeline. However, I learned last night that it does not like 720/60p!

Thanks once again.

Quick time Captured in FCP in Vegas 8
 
I run into a trouble. Have got lot of footage captured in FCP 2 from Canon XH A1. My Mac went to hospital for a week. Now I got project at hand (deadline 18th Feb!) and need to process, edit the files in Vegas 8. When I drag the .mov file onto the time-line only stereo sound track appears no video track above it.

Would people please advice how this can be cured?

Many thanks,
Pavel
