h.264

> I was under the impression that we had the latest codec. Could someone shed some light on this because Quicktime Pro uses it.

Unfortunately, Vegas does not use any of the codecs from Quicktime Pro. You need to use the Sony AVC or Main Concept AVC render types to get h.264. Alternately you can render to a lossless format and then encode in Quicktime Pro using h.264.

Thanks for your reply.

Would you elaborate on your last two sentences? Especially the latter one; which lossless format?

Thanks!

Sure. In the first sentence I was trying to say that if you use File | Render As… and look under the Save as type you will see MainConcept AVC/AAC (*.mp4) and Sony AVC (*.mp4;*.m2ts;*.avc) as types that you can render two. Both of these use the MPEG-4/h.264 codec. This will not be Quicktime format but it will be h.264.

In the second sentence, by lossless format I am refering to codecs that simply compress but don’t throw any information away. Rendering Uncompressed will, of course, be lossless. Also the Quicktime Animation codec is lossless, as is Huffyuv and Lagarith but these two do not ship with Vegas and you would have to download and install them.

So one solution might be to render as Quicktime Animation out of Vegas and then drop that into Quicktime Pro and render as h.264. This workflow will preserve the full quality coming out of Vegas and give you the h.264 file you want with Quicktime Pro.

John,

That is some very interesting information.

In addition, every render I have tried of my 1920×1080 AVCHD footage has given me black bars on the ends when played back in Quicktime Pro. The same was true when I tried the Animation render you suggested. I will continue to experiment but would like some help.

Jeff

P.S. I contacted Apple and they do not provide tech support for their $30 Quicktime Pro software. Incredible!

I successfully rendered a MainConcept AVC and it played with Quicktime! I don’t think I need to mess with Quicktime Pro now.

Question: The audio sync is off a few frames. Is there something that I can adjust in the render settings?

Not sure why the audio would be out of sync if it’s in sync on the timeline. I would try the Sony AVC or Quicktime Pro and see if it is any better.

I am also experiencing lagging from playback on the timeline.

Is this typical? Is it the AVCHD footage?

I have 8gbRAM with 1 TB hard drive but I just found out the graphics card is a cheap GeForce 9300GE. I also am running this on a Vista 64bit machine

Any one have any thoughts? I am at a crossroad here. I still can get a refund on this computer and have one customed built with XP 32bit and a better graphics card.

Anyone else have lagging playback problems?

Yes and yes.
You didn’t say what kind of a processor you have.
If it’s anything less than a quad core (and preferably an i7), then consider a CPU upgrade as that makes all the difference with Vegas.

You may want to consider a program like AVCHD UpShift (only $50) from NewBlue/VASST. It creates proxies that are easier for your computer to handle. A demo version is available.

Unless you’re using a program such as Magic Bullet Looks that takes advantage of the video card’s power, yours is probably OK.

AS long as you’re happy with Vista, I’d stick with it as more and more programs are going 64-bit so you’re ready for whatever comes along in the future.

[Jeff Mcguire]

My computer is a Quad core. I just am surprised that Vegas lags with a quad core, 8GB Ram computer. I really have to find a solution. I cannot edit in this environment.

But I am questioning the purchase of this HP computer that was supposed to be “high-end” with a nice 25.5″ monitor but with a low end video card and only integrated sound.

If you notice my earlier thread post, Vegas and Architect still do not recognize the drives. This is another reason to buy something else.

If I were to buy a custom built computer, can someone give me specs that would run Vegas rock solidly.

Jeff

Actually, mini-dv and AVCHD footage are mixed together and both lag, causing out of sync audio/video.

Would this affect the rendering because the MainConcept AVC video I rendered not only lagged on my editing computer but on another computer that I e-mail the rendered Quicktime file to.

Is there a frames setting in MainConceptAVC that I am not setting correctly.

Would someone share their MainConcept AVC export settings with 1920×1080 footage to get optimal results for the web?

Thanks!

Jeff
