You are in the right place, but you have to go through a lot of pages to finally get to the link.

thanks kkolbo. I get it now. I tried rendering a mainconcept AAC mp4 at 1440x1080 but it didnt turn out good. The colours went crazy or something.. seems to be missing one colour. any hints on the normal res u guys would pick for a HDV1440x1080i clip?

Rendering to smaller smaller at 720x576 25P made it looks bad too. A lot of pixalation.

Anyone know how to render a .mov like the trailers on Apple trailers with H.264 video & AAC 5.1 channel audio?

After viewing the info on the HD Quicktime (surround sound) trailers
I see that the trailers are using H.264 for video and AAC for 5.1 channel audio playback.

I have searched the net for a while but I can't seem to find an encoder doing that.

Thanks,

Yes, use Compressor. It's free in the box.

(The Final Cut Studio box. :O)

If your life is lacking one of those, have you tried QuickTime Pro ($29)?

Hi Coursedesign ,

Actually I was hoping to render via Vegas ;-))

Do you mean QuickTime 7 pro player?

I do have it, but how can I render a 5.1 surround .mov file using the player?

I suppose that I would have to render via Vegas a video file (avi?) and a multichannel audio file (ac3?) then render it out as .mov via quicktime player 7?

Or is there a standalone encoder from quicktime?

Btw: The 'Trailer J' 720p is a good example of a multichannel .mov

Yes, QT Pro "player."

It can do all kinds of conversions and encoding.

Craftech,
Where the *%&*($(#*% is the actual download link for that "super" software?
The site spouts on and on about how good the software is and that it's FREE, but I'll be damned if I can find the actual download link.
The joke's on me, right?
===========
Sorry Dan. I didn't notice this until someone bumped it back up to the front page. They hid the download really well. I went through the same thing.

Click Here to download it or go to this page , then go down to the bottom and click "Start Downloading Super", then scroll down about 1/3 of the next page and click "download and use", and FINALLY scroll to the bottom of the third page to find 4 download mirrors. One can link the actually download as I did, but one cannot link the actual download page.

Whew!

Hm.. it seems that QT 7 only accepts a single AV file for as input.
No use of rendering a seperate Avi and AC3 file.

I do see the AAC 5.1 + H.264 output.
But now the question is how do I get a single Video+ 5.1 audio file into Qt to render out that magical file?


Actually what I need is an AAC 5.1 channel codec which can be chosen in Vegas render menu when rendering a QT .mov file, instead of 'Outlaw, Alaw' audio codecs etc..

Any thoughts?
Thanks

You have a lot of control over the soundtracks in QT Pro.

I don't shoot surround, so unfortunately I don't have a simple recipe for you.

My experience with QT Pro is with multiple (alternate) audio tracks for other purposes.

Vegas has been a long time source of frustration for people who needed to make QT renders. It seemed like this was never a high priority, which at one time really was OK, because a long time ago QT was only used in a parallel universe.

Today it is difficult to be so insular. It creates more work for everyone involved, and it forced me to go multi-platform when I did not desire to do so.

You could try to see if Sorenson (http://www.sorensonmedia.com/) has a product that could help you.

I have found a good way for creating a multichannel H.264+AAC.5.1.mov

Here are the steps that I did to create my multichannel .mov.

1. Created multichannel audio project in Vegas 7 and outputted as
'.AC3'.

2. Converted the '.AC3' to 5.1 channel '.wave' with 'BeSweetGUI0.6b61'

3. Opened the 5.1 channel '.wave' in a QT window.

4. Using Vegas rendered an uncompressed '.avi' with the same length.

5. Opened the '.avi' in a new QT window copied the timeline via 'select
all' and 'copy'.

6. Back to the original QT window which has the (5.1 channel) '.wave'
and pasted it on the same timeline 'paste'.

7. Now I assigned the channels in QT so that the channels are routed
correctly to the speakers etc.
This can be done by
going to 'Window > Show Movie Properties menu item' there you can see
the properties of the individual AV files.

There I selected the the '.wave' file.

The maximum channels that the audio file has will be displayed there.
In my case it is 6, 5 + 1 for the subwoofer.

As default all the channels 1,2,3,4,5,6 are routed to 'mono' that means
that all channels are heard on all channels.

To assign the channels to the right speakers you have to manually route
them.

The original AC3 has channels ordered in its encryption.
After experimenting allot I found the right order for routing the
channels correctly.

1. Left
2. Right

3. Center
4. LFE

5. Left surround
6. Right surround

The titles 'Left', 'Right' etc can be chosen by a drop down menu beside
the channel numbers.

7. Now you can export the movie as H.264 ( Video) and AAC 5.1 (Audio)
with variable bitrate vs size vs quality etc.

Also you can save the current project as '.mov' but it will be quite
large.

I have made short video clip in 5.1 multichannel which you can view.
By synthesizing the designated channel names I could calibrate step 7 much more easier.

It's only 294 KB.

H.264+AAC.5.1.mov

Do not forget to set your audio system to 5.1.


Now I can finally make my own surround sound QT trailers! (big smile)
