Compressor on Intel Macs create byte reversed AC3 files

A co-vendor's MUXing application is unable to recognize my .ac3 file created by Compressor. I have a file inspection application from Manzanita Systems that also fails to recognize the .ac3 file.
I found this on the web:
- - - - - - - - - - - QUOTE - - - - - - - - - - -
another user had a problem with an AC3 recently as well. In that case the file was created with a wrong (well, it's not actually wrong but it's unusual for Intel PCs) byte order which makes it impossible for ProEx to handle the file. DVD Studio Pro sees it just fine.
If you've got a hex viewer you could find out by yourself. The first two bytes of an AC3 must be 0B 77. If they are shown the other way around then the byte order has to be changed.
- - - - - - - - - - - QUOTE - - - - - - - - - - -
I looked at my .ac3 file with a hex editor and it starts with 77 0B.
Then I looked at an .ac3 file that I created with Compressor on a G5 in back in October '06. It began with 0B 77. It was also recognized by Manzanita's MPEG-ID application.
I can't find anything on Apple's website regarding this issue. No Knowledge Base article; no update; nothing.
Whiskey Tango Foxtrot?
Anyone using the latest version of Compressor on an Intel based Mac to create AC3 files having problems sending them out to people who are NOT using DVD Studio Pro to handle the files further?
THIS NEEDS TO BE FIXED NOW.

I'm afraid you're right.
I just created a brand new DVDSP test project. The three new files created with Compressor work. The same files that didn't work in the project where they were PPC created AC3 files.
I was lost in many possibilities, since I had also notice that if I go in DVD SP 4 Preferences, in "Simulator" (I'm french and I don't know its real name in english...) then in "output of player" (same for my french translation) in "Audio" and that I select "numerical output - sp/dif" I have no sound played. If I select "Integrated output" then I can hear back my ac3 created with Intel Compressor.
On this same computer, with my other project, AC3 PPC created or recently created on my Mac Pro with my old A.Pack software (from DVDStudio pro 2 or 3, I think), are read without difference between these two outputs.
Finally, Do you suggest me to re-encode all my files ? or should I use A.pack instead of Compressor - maybe Apple Developpers will correct it one day ?
I'm also upset because, I has a .DTS from a trailer that was accepted and perfectly integrated in my previous DVDSP version, and that I can't use anymore !

Re-burn a DVD from .m2v and .ac3 files

Can someone explain to me if one can re-burn a DVD from Compressor after you've created the .m2v (mpeg-2) and .AC3 (dolby audio) files?
Here is my problem. I create a DVD with Compressor and have both the .m2v and .ac3 files on my drive. I'd like to save these and not have to re-compress the original ProRes file all over again and just burn these again to another DVD in the future.
How do you do that? Do you need another program to do this?
Any help appreciated!

No. Compressor can't use the elementary streams to build a DVD.
To burn multiple DVDs, save to a disk image (Output Device = Hard Drive) and burn that from that in Disk Utility.

How to Add .m2v and .ac3 files in encore?

I am doing my HD post in FCP and creating .m2v and .ac3 files using compressor. I would like to burn my DVDs in encore to try out blu-ray DVDs. How do I add separate .ac3 and .m2v files in encore?
Thanks

They get created as separate files originally. Just Import both and add each to the timeline.

DVD SP 4 and AC3 Files

I've been fighting the problem of exporting directly from FC Express to Compressor 2 and ending up with silent AC3 files. In searching the previous discussions, people advise using A.pack to convert a .aiff file. As far as I can tell A.pack is not shipped with DVD4. Right or wrong?
How do you get to Apple Inc to tell them about this problem?
Will they bother fixing it?
Any other suggestions?

Calvin,
See my post here: Guy Rhodes, "AC3 files made in compressor don't play in DVDSP" #5, 02:07am Oct 11, 2005 CDT
I found a workaround using .AIFF's that works using just Compressor, no A.pack.

It's impossible to create Enhanced Podcasts on Intel Macs. Please read.

After vast amounts of frustration trying to create an Enhanced Podcast on my MacBook Pro, I tracked down the source of the problem:
$ file /Applications/GarageBand.app/Contents/MacOS/ChapterTool
/Applications/GarageBand.app/Contents/MacOS/ChapterTool: Mach-O executable ppc
GarageBand uses ChapterTool to add the artwork and chapter stops to the AAC file, and ChapterTool is PPC only. Command-line applications do not run under Rosetta. Simply put, there's no way to author enhanced podcasts if you're using an Intel Mac. None. Every other tool out there to do so needs ChapterTool, too.
Pathetic. If you, like me, are an Intel Mac user who'd like to create Enhanced Podcasts, provide some feedback to Apple: http://www.apple.com/feedback/garageband.html

Simply put, there's no way to author enhanced podcasts if you're using an Intel Mac.
Sorry, but I don't buy this. Just created an Enhanced Podcast without any problems. And given that the whole podcast stuff was introduced together with the Intel Macs, we would have heard a lot of complaints here in the forum during the last 10 months. You're the first.

I have moved from a G5 Powermac to an Intel Mac Pro and am porting over Items from a Backup HDD. How can I access and use drawings and documents created on the PC computer on the Intel computer ?

Clarisworks, you need Appleworks, which will only work with Mac OS X10.6.8 or earlier. See this tip if you must go newer. Mac Pros with newer hardware configuration than July 20, 2011 can't use Mac OS X 10.6.8 or earlier without this tip and then it would be Mac OS X Server. I'm not sure if the new black Mac Pro supports that configuration or not.
iPhoto, there is an iPhoto for all versions of Mac OS X.
iTunes, there is an iTunes for all versions of Mac OS X. Note with iTunes versions 11 and later, which are needed for syncing with iOS 7 or or later, you will lose coverflow, if you liked that feature. Sadly you can't run an older version of iTunes from within Mac OS X 10.9 or later.
Sketchup: http://help.sketchup.com/en/article/60107 shows the versions that will work with intermediate Mac OS X versions, and this shows the latest version: http://help.sketchup.com/en/article/36208 be sure to click on the operating system you choose to use.
GIF - Viewing GIFs Apple's Preview can do that. Editing them, I like http://www.lemkesoft.com/ Graphicconverter.
DMG is able to be opened by all versions of Mac OS X. This are just "disk images" which store programs on a virtual disk that will open when double clicked. Frequently you'll find the installer of the said program inside. To find out if the program itself is compatible with 10.7 through 10.9, see http://www.roaringapps.com/
Otherwise see the resources on:

Compressor network rendering from Intel Mac to PowerPC Macs

Has anyone had any experience utilizing a Power PC G5 render farm for Compressor? I have the option of setting up a render farm utilizing up to 15 PowerPC G5s from an Intel Mac. Due to system limitations the Intel Mac will be running FCP 7 with Compressor 3.5 while the G5s are to be running FCP 6 with Compressor 3.0.
These 15 G5s are going to be sent to surplus if I don't take advantage. But I don't want to have 15 computers sitting around that won't render.
Any suggestions or experiences with such a situation?

I've had some experience using both Intels and PowerPCs in a QCluster. The hardware doesn't matter much, as long as all of the software is the same. Since you're using 2 different versions of Compressor and QMaster in this particular cluster, you will have compatibility problems. Also, depending on how you're connecting these machines, distributed encoding may not be a good solution.
A couple of weeks ago, I was testing a similar setup for a work group here. They had some extra iMacs that they wanted to network together to encode some Image Sequences. I ran some tests, and found that encoding without a cluster and with just a local cluster inside of just one MacPro was twice as fast as adding other nodes via ethernet.
But the basic answer to your question is that all service and controller nodes must have matching software versions. This is explained in greater detail in .

Using External Boot Drive with New Intel Mac Mini

I have a 1st Gen MacMini and use an external 7200 RPM Lacie drive as the system boot drive along with all the applications.
If I were to purchase a new Intel Mac Mini, is it possible to use the current external drive as the system drive or is there some conversion steps that would be necessary ?
Thank you.

You can use the hardware, but will have to repartition and reinstall the OS from the disk shipped with the new Mac Mini.
http://docs.info.apple.com/article.html?artnum=303220
If you create a disk image of the Lacie on your Mini, you can later use setup assistant to restore users and applications from that image.

How can I tell if I have the right restore disks for Intel Mac Mini

I have an "early 2006" (confirmed by S/N YM609***) Intel Mac Mini 1.66mhz Core Duo. I bought it used and the hard drive had been wiped. Both the HD and the DVD drive seem to work fine; hard drive passes SMART tests. I was able to boot using "Drive Genius" and can access the pre-install items like Disk Utility (and know that I need to use GUID formatting to create a bootable disk). Not knowing I could order restore disks from Apple I bought a set on eBay, p/n AHT VERSION 3A102 DISC VERSION 1.1 2Z691-5828-A, copyright 2006 on disks and included documentation (OS 10.4.6), but the install always fails 10-15 minutes along. I got the same results when trying to install via internal optical drive to a FW or USB external HD (told it to use GUID for the external HD), or external FW optical drive both to internal HD and to external USB hard drive. A friend tried to install full retail versions of 10.5 and even 10.6 for diagnostic purposes, using the built in HD and DVD drives, but those installs did not complete either; they did not try external drives. Is that the wrong restore version for this model, or even if the right "generation", does a set of restore disks only work with the specific Mac mini they were issued for like for example XP restore disks would? I've been told I can provide my s/n to Apple and for about $30 they will send me the "right" restore disks... anyone know anything about this? Could there be a hardware/firmware explanation for why the install fails like that? PS ran the extended version of the Apple Hardware Test with that restore disk set and it reported "no problems."
<Edited by Host>

Thanks. Actually I got the Mini from a computer recycling company I work with so I knew it might have problems and that I was taking an "as-is" risk. If the original disks were turned in with it, they'd been lost (that outfit took in huge piles of stuff every day; it was often luck of the draw for me to find something before it would be buried, damaged, etc., and not everyone who worked there had any idea of the possible value of things they received) for me to find things. The disks I got on eBay apparently were separated from the mini they'd been packaged for. An Apple Store rep said I could order restore direct from Apple just by providing my serial number; just wish I'd known that before I went to eBay. Since posting this I've seen another seller specifically claiming that the same-part-numbered-as-mine disc set they are selling will work with my specific type of Mac mini. I have an appointment tomorrow morning at the Genius Bar at an Apple store near me in case they have more suggestions. Will share what I know as things develop.

No "PDF Portfolio task pane" on Intel Mac!!!

Acrobat 9 Pro has different behaviors between Intel Mac and PowerPC Mac !!!
On Intel Mac, I cannot change the default layout of any PDF Portfolios, because the "PDF Portfolio task pane" doesn't show, so there's no way to touch the "CHOOSE A LAYOUT" button.
But on PowerPC Mac, everything is fine.
I think it's a serious bug which only affect Intel Mac. Please confirm this.
Thanks.
(I attached screenshot of new created PDF Portfolio window under Intel Mac and PowerPC Mac)

Hi, Steve
I just found the key to trigger this "bug". In Acrobat or Reader's Preferences, choose "International", and there's a "Choose Font" option. I can choose between "Application Default Font" and "GB18030 compliant Font" (I don't know if this later GB18030 option shows in non-Chinese environment).
If I choose the GB18030 option, I won't see the "PDF Portfolio task pane". I think I don't need this option, so I recover the old settings. (Obviously my Acrobat system files are not broken, but I cannot explain why simply delete all preferences in my home directory didn't work -- maybe this option are not stored in my home directory).

TUTORIAL: How to make PPC Plug-Ins work on Intel Macs!

Hi guys, I wanted to share this brillant method with you all, collect ideas and create a list of Plug-Ins, you have succeeded to make work (I guess nearly all PPc Plugs will work this way but lets better stick to facts). Maybe there is a way to work with more than 1 Plug - Feel free to report and contribute! Kudos goes to a dear friend of mine... Let' share some power...
"I noticed some people complaining about not being able to use Trilogy and Atmosphere on Intel Macs. There's a tricky way to do it that takes about ten minutes to set up the first time and after that is easy. It probably works for other PPC-only instruments as well.
Here's the outline: OSX for Intel contains a layer called Rosetta, which runs PPC software that hasn't been updated. (You might run Microsoft Word via Rosetta and not even know it.) In general, Rosetta is no good for audio software: you can't use it for a sequencer or a recording application. But it's good enough for a lightweight plugin host like Rax, which does nothing but serve as a host for Atmosphere. So you can load Atmosphere into Rax via Rosetta, then run it alongside a UB sequencer like Live or Logic.
The only tricky part is connecting the two together. You need to get MIDI out of your sequencer and into Rax, and you need to get audio out of Rax and back into the sequencer. The MIDI can go via an internal IAC bus. The audio can go via the handy freeware audio-routing utility Soundflower.
Here's how to set up:
-- download Rax version 1.2.3. (Version 2 and up won't work.) You can find it at http://macmusic.org/software/view.php?id=395 . Use the serial in SerialBox to install.
-- download and install Soundflower from http://www.cycling74.com/downloads/soundflower
-- in Audio MIDI Setup, create a new IAC bus. Instructions on how to do this are at http://www.spectrasonics.net/news/Creating-an-IAC-Bus.html . Name it Rhino. (You can name it whatever you want, but in these instructions I'm going to call it Rhino.)
Now you're ready to go.
-- Open your sequencer and create a MIDI track and an audio track. Set the MIDI track's output to Rhino. Set the audio track's input to Soundflower 2ch.
-- Open Rax and load Atmosphere. In the Preferences, go to the Audio tab and set Audio Device to Soundflower 2ch. Now go to the MIDI tab and, under MIDI Inputs, make sure Rhino is the only thing checked.
You should now be able to send MIDI from your sequencer to Atmosphere, and then hear the audio through the sequencer. One last stage is to sync Atmosphere to your sequencer's MIDI clock, so that tempo-synched effects will work properly.
-- Still in Rax Preferences, on the MIDI tab, set the MIDI Clock dropdown menu to Rhino. Close the Preferences window. At the top of the main Rax window, make sure the Ext. Sync box is checked. The Tempo window should say 0, which means Rax is following the sequencer's master tempo.
And you're done. Save the Rax document and you can open Atmosphere with a single click. Trilogy works the exact same way, obviously.
If you want to use multiple instruments from Rax, you'll need to use SoundFlower 16ch and send MIDI on a different MIDI channel for each instrument (using the same IAC bus).
Anyone who's tried this, please post your results in this thread. Especially, try out other PPC instruments, and try using multiple instruments at the same time, and let us know how it works for you."
Maybe one of the Admins wants to sticky this
With my very best,
Vic.

There's another shortcut I've used successfully in order to access 'old' PlugIns on an Intel MBP :
Just use Logic 6 - and take full advantage o' that ole rotatin' rosetta
Meaning : Other than with native Logic versions 7 and 8, Logic 6 has to be fully emulated by the rosetta engine, and if your intel mac is fast enough, it does so very well - thus including all PPC PlugIns you still may have installed. Also works fine for PlugIns that were converted via FXpansion's VST-AU manager.

IUnitOfMeasure returns wrong format on Intel Mac -- CS2 SDK !!

Hi, I am trying to convert the Point value to the current document measurement system and it is working fine on other Macs except Intel Mac. It is returning some weired trailing decimal values when run on an Intel Mac. Any ideas how to fix that. On Intel mac the returned value is something like "4.180599999999999 in" when expected is "4.1805 in: InterfacePtr<IUnitOfMeasureSettings> iMeasurePrefs(docWorkspaceRef, IID_IUNITOFMEASURESETTINGS); int16 vUnitIndex = iMeasurePrefs->GetYUnitOfMeasureIndex(); InterfacePtr<IMeasurementSystem> ms(gSession, IID_IMEASUREMENTSYSTEM); InterfacePtr<IUnitOfMeasure> vCurrentUnit(ms->QueryUnitOfMeasure(vUnitIndex)); vCurrentUnit->Format(vCurrentUnit->PointsToUnits(pointY), result); Any clues !! thanks shwetag

Roger--
Thanks for the reply. According to the man page for hdiutil, the parameters I'm using should allow me to create a bootable Intel ISO file on the PPC. For example, I've created a work directory with the files to be burned inside it. The command I've used is:
*+hdiutil makehybrid -o new.iso work/ -iso -eltorito-boot work/isolinux.bin -no-emul-boot+*
But, no workee. That's what puzzles me. If it's the same OS version, why doesn't it work? Unless there's some code in the command that's tied specifically to the hardware type that the command is running on...

How do I create a DVD from existing M2V and AC3 files?

I have previously used Compressor 4 to render a M2V file and an AC3 file from which I burned a DVD 'job'. Now, a week later, I wish to go back and burn another DVD from these files, (without rendering them again). How do I use these EXISTING files to create another DVD (using Compressor 4)?
Thanks,
Geoff

If you anticipate that you may need multiple disks, the way to do it is to select Hard Drive as your output device/ That makes a disk image, from which you can burn multiple copies.
WIth the separate files already created, you could bring them into an authoring program like Toast. But if you want to re-use them in Compressor, I think your only option is to multiplex them in something like MPEG STreamclip and bring the new file back into Compressor.
Probably easier to redo the Compressor job with the original source.

Running an Intel Mac on a Wireless Network with other Power PC Macs

I know changing the Airport to WPA encryption will allow an intel Mac with either Mac OS or WinXP OS to access the airport.
If you have powerPC Macs also, what encryption will allow both Mac (intel and powerPC) and WinXP to access the airport?
Right now either WEP for all Macas or WPA for intel Mac (Mac & WinXP).

Mac Mini (Intel), iMac, eMac, iBook, G4, & Powerbook (all powerPC) Mac OS X (10.3.9) also 10.4+

Hi Sherwood!
If I recall correctly, an update to Windows XP (assuming you're using Windows XP) added WPA support to the existing WEP support. The same applies to Mac OS X.
Regardless, if both OSes are up-to-date they can use either WEP or WPA. But WEP and WPA should not be used at the same time for the same wireless network. Choose one and set your Airport first (create your infrastructure) and then set all computers to connect using that same security (add computers to your infrastructure). I suggest using WPA becuase it is more secure than WEP.
This link indicates when you can use WPA on your Mac and this link indicates when you can use WPA on your Windows system.
Hope this helps! bill

OK, I have a .mov and .ac3 file output by Compressor. How do I make a DVD from these?

I'd like to use Toast 8 but I don't know where to drag the files...Toast help is no help at all...

First off, you should have compressor turn your .mov into an mpeg-2 file with an .ac3 file. Once you've done this, you simply select the Video button in Toast (I'm on Toast 10, but I think 8 was the same). Next select your Menu style from Toast and type in your DVD name. Finally drag your mpeg-2 file over into the Toast window. It will then ask you "do you have audio for this file?". Drag the .ac3 file over and have it burn the DVD. If you've done everything correctly it shouldn't re-encode your video, but simply add the menu to your already encoded files.
As an alternative, you could have Toast do the encoding as well. If you choose this route, you simply drag your original .mov video file over to the Video window. At this point there are some choices you need to make about how Toast will do the encoding. This way takes longer as Toast has to encode both your video and the menu you created.
