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.

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.

Lost my m2v and ac3 files and want to recosntruct from a final DVD

I lost the compressed files m2v and wav that I used to generate a menu driven DVD at the time I was using a Windows based PC (I used Pinnacle Impression with a menu to generate the final DVD.
Now I no longer use this PC and made the big step to the Mac world in buying a MacPro with FinaCutPro and DVD STudio Pro. The only thing I have left is the final DVD with its usual contents (VOB files).
Is it possible to find a way to import the VOB files (with the sound) into DVD Studio Pro, split it by Chapter and re-create a brand new menu ? Or using Compressor or FCP in intermediate steps before using DVD Studio Pro ?

You can use * MPEG Streamclip * to extract the original m2v and ac3 files from the VOB file without any quality loose, and use such files in a new DVDSP project. You'll have to rebuild your menus and navigation.
Hope that helps !

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.

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.

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.

Best way to burn m2v and ac3 files to DVD

I recently compressed an exported final cut movie into DVD files - an ac3 audio file and an m2v video file.
I used Toast to burn them to a DVD but it did not finish correctly. I can hear the audio, but there is no video on the disc...just some graphic.
What is the best app to use to burn these files to a DVD? DVD Studio Pro? I don't need a menu, all I need is for the disc to play when it's inserted. I find that DVDSP is somewhat complex for burning a simple DVD.
I am going to try doing everything in Toast this time, but I've read that Toast is slow when it comes to encoding. Compressor was able to encode my 1hr 40min video in under 30 minutes....

My guess is that you added the .ac3 file directly to Toast and ended up with a Toast music DVD. The setting to use in Toast is DVD video in the Video window. Add only the .m2v file. Toast automatically adds the matching .ac3 file if it has the same name except for the extension and is in the same folder. If Toast can't find the audio it asks you to locate it.
You can choose Save as Disc Image and then mount the disc image for preview in DVD Player. If all is good burn the disc image to DVD using the Image File setting in the Copy window.

How to directly burn .m2v and .ac3 files on a DVD?

I made a DVD movie processing on Compressor but I forgot to select the "Job Action" (Create DVD), so now I have the 2 files .m2v and .ac3 but I have to burn the DVD. How can I do without re-processing the original movie?
Thanks

If you have Toast or DVD Studio you can use these files. If not, you'll may need to re-encode the movie.
But try this if you saved the the Compressor project that made those elementary streams. Reopen it and slightly change the name of the output files (say, by adding a numeric prefix to each name). When you do the yellow warning triangle should go away. Change the job action to burn DVD and submit, If it works, you should get a near-complete progress bar in a matter of seconds. Then you should be able to burn your physical disk or make a disk image for multiple copies.
Good luck.

How to burn blu ray disc with H264 files and ac3 files?

Hello,
I have tried many times to burn a bluray disc with FCP and compressor and they always end up not successful. After spending days on testing different settings, I finally managed to only get it to work if I tried
1) outputting to Hard drive as opposed to burn to bluray
2) Turning the default bit rate down from 35Mbits to between 15-19Mbits.
Then I used either disk utility or toast to burn the disc image onto the Bluray disc.
I have however on a recent job forgotten to switch the setting on compressor to output to harddisk and instead set it to burn to Blu-ray. Big mistake. Again I end up with a h264 file and an ac3 file, and nothing I can do with them after 24 hours of rendering. Oddly, the compressor says "successful" but nothing is created but that 2 files.
My question is (before I restart the whole 24hr rendering process again) - is there anyone who can help me use the .264 file and the ac3 file and create the blu-ray disc with the menus again without having to re-render all over again? I have not been able to find anyone to provide me with a solution or find any where online that helps with that.
Desperately ...
Yee-wei

Hello,
Sorry but the instructions in the manual (online and offline) do not answer my question. Yes I do have a bluray burner, it is a matsushita BD-MLT SW-5584. I wrote in my post that when I set it to output to HardDrive, it will create a dmg file nicely for me to burn using disk utility or toast.
But when set it to burn to Bluray disc, nothing gets done. I just want to find out, with the h264 file and the ac3 file that gets created in the process of creating the dmg file, can I still burn the disc or create a dmg file from them without having to re-render the whole thing again.
Maybe you never tried burning a Blu-ray disc with FCP or compressor before. Let me explain how it works. When you submit the project to process, it will create 2 files - 1 ac3 audio file and a .264 file. After that 2 files are rendered (which takes 24hrs for my 2hr 30min HD clip), it will use that 2 files to create your Bluray disc or your dmg file. Problem occurs when it doesn't burn the disc and you are left with just the 2 files that cannot be used to burn the project again. My question is : is there anyone who knows how to set the compressor to see that the 2 files are already created and just continue to create a dmg file?
Hope my question is clearer now.

XVid and AC3 file (no sound)

I have done a search for an answer to this but nothing has really been useful so I figured I would try again.
I have a large video that is in XVID format with AC3 sound. It plays the video fine but has no audio. When I first started up the video it told me that Quicktime was missing required software. I didnt follow the link and it hasnt given it to me again. Is there a way to play the audio and the video?
Any help would be greatly appreciated.
Jamey

It plays the video fine but has no audio.
The QT structure does not support AC3 audio "natively" nor does it support a "pass through" option like the Apple DVD Player.
Is there a way to play the audio and the video?
You can add the A52 QT component, but this only supports stereo playback via core audio.

How do I merge a 264 file and ac3 file exported from compressor?

I am trying to create an .mts file from these two streams.
Anyone?

You make the transport stream in Compressor. You should try the Compressor forum and give the version number. I haven't used the current version and don't know if the functionality is available in it.

How do I combine an .m2v file and an .ac3 file into a .mov file ??

Hello,
I had a question regarding Demuxing M2V and AC3 files so that they can be combined into a .mov file.
A few years ago I converted a .mov file into an .m2v and an .AC3 using Final Cut Pro. I lost the FCP Project and .mov files and only have the .m2v and .ac3 files left. When I tried to combine them together in FCP, the audio did not match up anymore even though it matches on DVD Studio Pro. I was told that I needed demux the files. How do you do that ???
Thanks so much for your time !!!
Happy New Year!

Doug,
Am posting the workflow discussed in my last email here in the event others might be interested.
Best workflow I've found to resync and convert the M2V/AC3 elementary stream files to an MOV ProRes422/AIFF file are as follows:
1) Convert the AC3 audio file to AIFF. (My system is configured for AC3 so I used QT 7 Pro here. My only compaint at this point is that my original AC3 file was DD5.1 and my QT 7 Pro component only supports stereo conversions.)
2) Simultaneously drop-import the original M2V file along with the converted AIFF file to MPEG Streamclip (requires the QT MPEG-2 Playback component be installed).
3) Sample playback of the combined data to ensure audio and video are correctly in sync throughout the file.
4) Use the MPEG Streamclip "Export to QuickTime" File menu option to export the current date to the target Apple ProRes422 video target you want and pass the AIFF PCM audio through to the MOV file container without further processing.
5) Import the ProRes422/AIFF MOV file to your FCP bin and reset project default codec use to match imported file when asked so you don't have to do any re-rendering for final output.
6) I re-checked file playback in the Preview window to ensure A/V was still in sync before beginning edits in the project timeline.
All went well for me using this workflow. You may want to give it a try and let us know if it worked as well for you.
Good luck!

PAL dvd Menu not accepting audio files

I need some help!
I am converting an NTSC DVD to PAL.
My menu is a short video loop with audio. But I cannot seem to find an audio format that the menu will accept.
I tried to make a .wav and a .ac3 audio file so far but neither is working.
I have .m2v and .ac3 files in my Timelines and they all play their audio.
How is the Menu different?
Any suggestions?
W

Sorry about this but more information is needed here.
1 - What is your OS and system spec?
2 - How are you doing the conversion from NTSC to PAL?
3 - Are you sure that the frame rates match?
4 - Is either the menu M2V file or the menu AC3 file carrying a different frame rate - they should both be the same - 29.97 drop frame or non-drop (drop frame is more usual but as long as both match it should be okay)

Grey screen on final burned DVD, used Compressor and DVD Studio Pro 4

Trying to create a standard dvd from a 2 hour and 8 minute 720x480 mov file. I have used compressor to create a mpeg2 as well as an ac3 audio file. After looking at other posts, I feel that what i've done in compressor is ready to be imported into DVD Studio Pro. I changed my preferences in DVD Studio Pro to support my mpeg2 and ac3 files coming in from compressor. After I import, they import very quickly. The playhead lets me scrub through the video fine, but when I go to the simulator, I get a grey screen.
I'm trying to output this file onto a dual layered Standard DVD. The fact that my video was originally an HD mp4, converted into .mov should not matter once it's converted into an mpeg2, correct? Mpeg2 is the standard DVD format.
I've also messed with the markers in DVD Studio Pro because I've read that the Automatic settings for the "break layer point" are not that "Automatic" I've seen other posters saying to add markers in the gap where the DVD laser should switch from layer to layer, but still my output burned DVD and simulator remain a grey screen!. Please help, I've referred to many posts and I believe that I've done everything right except maybe one or two things. So Close! Help! Thanks!

What were the chamges you made?
Does the m2v file that Compressor output play OK in QuickTime?
