Missing audio on AC3 encode

I have a small mix that plays fine in Soundtrack Pro. When I export the mix as an AC3 file 2 of the dialogue clips are missing. When I go back to my STP mix they are still in the mix but silent. If I reassign them to a different sub mix and then back to the original sub mix they play again. Unfortunatly there is no way to get them to play in the AC3 encoded mix. Does anyone have an inkling about how to fix this.

I'd start over with a new multitrack and place those files in it to try and track the problem.

Free AC3 encoding workflow

Like most of you, I was annoyed to find out I couldn't create AC3 surround sound files with my CS4 software, and also that we got downgraded from Audition to Soundbooth. We all paid a lot for it! I know many people have ranted about that already, so enough said.
Here is a workflow that gets around that problem without ponying up for the SurCode Plug-in, and/or buying Audition!
To convert your mixed 5.1 audio, or stereo audio, to the DVD standard AC3 file that Encore wants, download the latest version of Audacity here: http://audacity.sourceforge.net/ It is available for Mac OS X, Microsoft Windows, GNU/Linux, and other operating systems. If you don't know already, it's free!
Now, before I start getting flamed, about Audacity, it works great! The UI is not the most modern, but the quality is top-notch. I've used it for years and most complaints about it are unjustified.
You'll need to download the latest version: "Beta: 1.3x - for advanced users." There will soon, I hope, be an Audacity 2.0 stable release. Until then, use the Beta release for this workflow.
Note: I'll focus on Premiere Pro CS4, because that is where I originally troubleshooted this, but something similar will work for the other Adobe products that use sound.
Workflow:
Create your mixed 5.1 surround sound audio in Premiere, and output the audio only by going to File > Export > Media, and selecting "Windows Waveform" as the output. You should only have "Export Audio" checked. Verify the format in the Summary section. You should see something like: 48000 Hz, 5.1 Surround, 16 bit. Now under Audio codec, make sure "Uncompressed" is selected. Click Okay, and Adobe Media Encoder should launch. Click "Start Queue" and your audio file will be created. You'll get an interleaved 6 channel wave file. Not all applications will open it, but Audacity will.
Note: When you mix your surround sound in the Audio Mixer, you'll place your little "Puck" where you want the sound to come from. Picture yourself in the middle of the "dish," if it's a puck, isn't it in a rink, as in hockey rink...ah, but I digress. Anyway, you'll notice that volume meters in the 5.1 (6 channel) Master section are laid out in the following order: L,R,LS,RS,C,LFE. Also, if you open a 5.1 audio file in the Source panel, you'll see the same order from top to bottom: L,R,LS,RS,C,LFE.   Soundbooth also does it that way. Ahh....Adobe...nice try.
The actual channel order should be L,R,C,LFE,LS,RS. That's the order that you'll probably have to assign in the "Audio Output Mapping" section in the properties menu to get your channels to play correctly with your surround sound hardware. L,R,C,LFE,LS,RS is also the order that interleaved files use. So after you create your 5.1 file, and open it in another audio program that displays them in the "proper" order, like Audacity, you'll see your tracks laid out from top to bottom in that order. I'm not sure why Adobe does it that way, but oh well.
Surround sound primer:
The LFE channel is not, despite popular misconception, a subwoofer channel. Bass from all the channels in a surround sound Amplifier is summed and sent out to the Subwoofer. The LFE channel is supposed to be used only for very low frequencies, to create extra ...oomph. I think that is the technical term. It is not supposed to be used for bass frequencies from the other tracks. It is for explosions, dinosaur footsteps, ...etc.
Audacity will open DVD ".vob" files, and even let you select which stream (usually Language) to open. As an example, open up a movie with some action in it like Ironman (The movie starts at "VTS_03_1.vob") and look at the LFE channel. It's the 4th track from the top in Audacity. You'll see it's silent except at parts where there is thumping AC/DC music at the Intro, or explosions. It's not used as a subwoofer channel!
With that in mind, you may have noticed, unless I'm missing something, that there is no way in the Premiere Mixer to assign an audio track only to the LFE channel. Sure, you can dial up the "Bass Clef" knob to 0.00 db, and send a mono channel's audio to the LFE channel, but there is no place to put the "Puck" that only outputs to LFE. There is one for the center channel, but without someplace to put it, your 40 Hz dinosaur footprint "Thump" is going to also be assigned to some of the other channels. Which channels depends on your "Puck" placement. This is not correct. Again, unless I'm missing something, Adobe needs to correct this oversight. We'll get back to this problem with a solution later, but first let's continue with the AC3 issue.
At this point you should have your wave file. If you want to apply any global changes to all 6 channels, you can open it in Adobe Soundbooth and trim the beginning or end, and apply effects to the entire file. You cannot, however, make changes to individual channels. Audacity will! We'll get to that later.
Encode with Audacity:
Install the software and go to Edit > Preferences > Libraries, and click on "Download" for the "FFmpeg Library." This is the library that Audacity will use to create the .AC3 file. Once installed, the library version should show up next to "FFmpeg Library Version" While the "Audacity Preferences" window is still open, select "Import/Export" and select "Use Custom Mix", this is used to export a 5.1 channel file. Now you're ready to open your .wave file from Premiere. Drag and drop it in the Audacity workspace and you should see 6 mono tracks laid out from top to bottom in the following order: L,R,C,LFE,LS,RS. Audacity will let you edit the individual tracks, unlike Soundbooth, thanks Adobe. But for now, we'll keep it simple. Set your "Project Rate" in audacity in the lower-left corner to what you want the AC3 file to be. For DVD, chose 48000 (Hz). If you leave it at 44100 (Hz) Encore won't import it.
Your almost done. Now let's export the file. Go to Files > Export... > and select "AC3 Files (FFmpeg)" in the "Save as type:" drop-down. Click the "Options..." button and set the "Bit Rate:" for your file. For 5.1 AC3 audio, probably 448. Now enter a file name and click "Save." This will open the "Advanced Mixing Options" window. This allows you to re-map the tracks to a different channel order. It should be correct, and it should show "Output Channels:" set to 6. Press "OK" and you're done.
Presto, you have a 5.1 channel AC3 file. Use that in Encore, or whatever DVD creation program you use, and when you play your DVD you'll have full 5.1 audio coming out your surround sound Amplifier. That is if you have one.
Test your file:
If you want to test your file, you can do a couple of things. Since Soundbooth and Adobe Bridge won't even open AC3 files, and Encore will open but only play the Left and Right channels in the preview, you'll have to either import the file into Premiere, or use another media player.
If you got Premiere to play your surround properly, then you can drag and drop the file into the "Project" panel and preview it from there. You will hear all 6 channels in the correct speakers, but I did notice that the quality is not very good. Maybe Premiere doesn't decode AC3 all that well. I heard some crackle that isn't in the file. How do I know it isn't just a bad encoding job by Audacity? Because I played the file with the VLC media player, and Cyberlink PowerDVD on the same computer, and also on a DVD in my home theater system with no artifacts. Maybe Premiere doesn't decode AC3 files well.
The VLC player, will play almost any file in the known universe, and at least on my computer, it automatically played the AC3 surround file, created by Audacity, with all the channels mapped correctly. That's right, full surround out my speakers with only default settings. It's a great player. Get it for free here: http://www.videolan.org/
Test with Encore:
So far so good. Now open Encore, drop the AC3 file in an empty project, throw it on a Timeline and build the project without Video, It will autoplay without a menu this way. If you set the End-Action to the same AC3 file it will repeat continuously. Either burn this to DVD-RW and test it in your DVD player, or better yet, Build the project to a DVD Image instead, and mount it in a virtual DVD   Drive with a program like "Virtual CloneDrive."
If you don't know what that is, or how to do it, it is very simple. Go to: http://www.slysoft.com/en/ and download "Virtual Clonedrive." It is free. It tricks your operating system into thinking you have another physical DVD drive. In fact, it can create up to 8 virtual drives. Now you don't have to waste time burning, and erasing DVD's every time you make a change to a project. You can build your project as a DVD Image from Encore, save the .iso file to your Desktop and "mount" it (load it) in Virtual Clonedrive. You're computer will now think you loaded a DVD into a physical drive, and launch whatever DVD player you have installed. Mine launches "Cyberlink PowerDVD" which plays the AC3 audio-only DVD in full surround sound on my computer.
Building and testing projects this way will save you endless hours. If you need to make a quick change, just "Unmount" the .iso in Virtual Clonedrive, rebuild your project to the same filename, and "Mount" it again. Instant testing!
Now, as promised, back to that LFE Channel problem with Premiere that I mentioned:
Audacity will let you modify the individual channels in your interleaved 6-Channel file. So don't put anything in that channel in your Premiere mixer. Leave the "Bass Clef" knobs at full CCW position ( -00 db ). The bass from the other channels will go to your subwoofer automatically in your Amplifier.
Now if you have some low frequency effects files, open them in Audacity. You can open multiple instances of Audacity at the same time by going to "File > New." Then, copy and paste them into the LFE Track at the correct point.
Audacity newbie Hint: Audacity doesn't yet have a "Mix-Paste" function, so to avoid altering the track length as you paste in your clips, do the following: Select the LFE track by clicking on it's info area. The info area should say something like "Mono, 48000Hz" Then press "Delete," That will remove everything from the track. Now copy and paste your clips into the track by clicking once with the "Selection Tool" where you want the clip to start, and selecting "Edit > Paste." If you need to fine tune the position of the pasted clip, use the "Time Shift Tool" to move it left or right. If you work from left to right, then you won't push clips over when you paste new ones in.
There is another way to do this by opening up new tracks, using the "Mix and Render" function, and re-ordering the tracks to maintain the L,R,C,LFE,LS,RS channel order. But that's for advanced users.
Where to get thumpy effects?:
Remember, Audacity will open DVD ".vob" files. Just remember to get permission from the copyright owner. HeHe.
PS If you can't get your surround sound to work with Premiere on your computer, see my other tutorial.

After further research, there is a better AC3 encoder out there than the FFMPEG that Audacity uses. It is a more sophisticated implementation of the format. Unlike FFMPEG, it uses floating point numbers instead of integers internally, among other things. It is also updated periodically. Although the pace is glacial.
You can read about it here: http://aften.sourceforge.net/
The easiest way to use it is with a graphical front-end like "wavtoac3encoder" found here: http://code.google.com/p/wavtoac3encoder/
You don't need to change anything from the default settings.
Just follow my tutorial above and instead of using Audacity to create the AC3 file after you are done editing, output the multi-track file in .wav format uncompressed from Audacity. Then drag and drop it into "wavtoac3encoder"and create your file.
If you don't need to edit the multi-track .wav file from Premiere in Audacity, then just drag and drop that file into "wavtoac3encoder" and encode.
The quality, although probably not as good as SurCode, sounds good to me.

Ac3 encoded video, SPDIF but my receiver switches to ste

Hi all,
I've got this problem, I got a video witch says to have ac3 encoded audio. Once tested with Gspot codec information that seemed to be true. When I run the video an icon appears of Dolby digital bit stream out but my external receiver switches to digital stereo in stead of switching to 5. surround sound witch the receiver normally does when I run ac3 encoded files....
All the settings are set to SPDIF pass trough. Other ac3 encoded files give no problem, perfect 5. surround sound...
So whats wrong here... Is the video file a faker or what
Greetings and thanks in advance, Thomas Voortman

It says the following:
Audio:
Bit rate: 224 kbps
Audio format: AC-3 ACM decompressor
Off course it gives more info, but i guess that isn't necessary?
I already checked this summary but didn't knew how to change this settings. I guess that the audio format is the prob? Is it possible to change it's
Thanks in advance.
Greatings, Thomas Voortman

Mac alternatives for affordable 5.1 AC3 encoding?

A musician, I was looking into DVDSP 4 so I could get into adding 5.1 audio created in Cubase SX to video. I have FCPE, which has more than plenty of video production features for me, so obviously I don't want to spend $1300 just for 5.1 AC3 encoding.
Is there an alternative for 5.1 dolby encoding for mac users under the $500 mark? Do I need to go over to the dark side for this? (I've seen a couple apps for Windows).

Hi again-
Okay, about DVD-A: you asked about playback options, specifically the cable issue (six analog or one optical specifically.) It depends...how's that for an answer! Actually, it depends on your player and preamp/receiver. I take it since you knew enough to ask the question in the first place, you're familiar with the copy protection involved with both DVD-Audio and SACD for that matter. They were originally not allowed to be sent digitally from the player to the preamp. I believe it's the way the labels wanted to try to put the copy genie back in the bottle that they lost from CDs. Anyways, unless you've got something like D-Link from Denon (for only their DVD and receiver) or even some FireWire units that talk the same encryption on both ends for digital it won't work. Me, I have to rely on the six audio RCA cables to get the signal from my Denon DVD player to the Outlaw Audio preamp. The normal digital cable I've got connected will not pass the DVD-Audio or SACD stream along from the player. Another case of me, the end user, being treated as guilty until proven innocent. But that's another story.
DTS CDs: I've found that the medium I use, either DVD or redbook CD, is rather irrelevant when it comes to providing a DTS stream to my preamp- it likes both equally well, and recognizes them identically as DTS. The most important thing is the digital steam that's DTS encoded- once it leaves the player, it looks the same going across the wire. At least that's been my experience. That's why DTS originally could release DTS CDs- as long as their was a digital connection to a preamp that can decode DTS, a normal CD player works fine. In fact, I can also use the six channel input to play it back as my DVD player decodes the DTS stream internally and often do. My 14 year old CD player won't decode DTS, but with the digital out it can only pass the stream along to an outboard decoder.
As an aside, I can expand on this a bit. To augment my modest home studio monitors (two Event 20/20's), I bought an okay 5.1 speaker setup, the Alesis ProActive one that is more or less a rebranded Logitech but with six analog 5.1 inputs (important to me for mixing from my MOTU 828) and detachable speaker wire because I'm a prude that way. Anyway, out of the box and connected via one optical cable from my G5, I could get it to play anything except my DTS encoded tracks. Actually it played them- think white noise. Not good. I did some Googles and found out that the volume coming from the Mac had to be pretty much pegged to the max for the DTS decoder in the ProActive brain to recognize the digital stream. Once I did that, I got the DTS 5.1 soundtrack just fine.
Too bad about IM not being prompt. Like I said, I like the product and I've had no issues and I've needed no support as the product is self-documenting. It does one thing and does it well for me. Hopefully someone from their sales team will find this thread and convince the company to arrange at least a basic sales page with the website. As I said earlier, I did many Googles over the course of maybe a month and never found the right query to hit IM's page, and it was DTS that finally pointed me to their website.
DVD Studio Pro is worth it, if only to allow you to share your recordings to create DD mixes with pretty menus and the such. If IM ever gets off their butt it's worth at least a demo since you could encode and burn both DD and DTS tracks to the same DVD and see what you'd like better.
DVD-Audio is (was?) a good format (pet peeve- let me leave the TV off please- I hate having to navigate a menu to start track 1!!!) Of course there's enough confusion in the home theater world now that explaining to someone that you'll need six more cables isn't easy. Chicken and egg too- the software titles never panned out for the masses. And don't get me going with Sony screwing up yet again by not releasing stuff like the entire Pink Floyd catalog in SACD at launch of that format. I've heard enough 5.1 mixes of both classic and new recordings to know that I'm completely sold on the notion of surround music. Unless you like classical music, the choices are a bit thin of course. I do agree with you- hopefully the HD versions of DD and DTS will give the industry a kick in the backside to release more multichannel music.
Hmmm...encoding DTS via Virtual PC, eh? Shouldn't be too bad. Then again, if enough people from Apple who have the power to do something realizes that you, me, and at least a few others are interested but have to resort to a Windows solution for a multi-media codec, maybe they'll release such a beast. Then again, I'm one of the many waiting for a decent alternative to Quicken since Intuit screwed up the initial OS X version and never quite fixed it...
Cheers!
Marty

Importing Video with AC3 encoding

Hi,
I am completely new to FCE 4.0. For years, I've been using my Sony DVD Camcorder (DCR-DVD403) to capture my raw footage. The camcorder an onboard Dolby Digital AC3 encoder which I use all the time. I import the video to my PC since using the Sony Picture Perfect software to preserve the AC3 encoding. However, when I import it into FCE 4.0, the video plays fine but I get now audio whatsoever.
Any ideas how to fix this?
Thanks,
Randy

Thanks for the tip. I ended up using the MPEG Streamclip function "DEMUX to M2V and AC3" to divide the original video file into a discrete video (.m2v) and audio (.ac3) file. I then imported into FCE 4. I was not sure how to load the two files into the Preview window, so I instead chose to drag each file separately into the Sequence window. To get all 6 audio channels I had to add 2 more audio channels prior to loading. FCE requires that you render the entire clip first after completing the render, I was able to replay the clip with full 6 channel Dolby Digital.
There is still one thing that I cannot figure out. Which audio channel corresponds to its respective audio output (ie. A1 = Front Left, A2 = Right Left, A3 = Centre, ...).
Anyone know the answer?
Thanks,
Randy

AC3 encoding is impredictable in Compressor 2

The Dolby AC3 encoding in Compressor has some major volume problems. Normally when using Dialog normalization at -31 (for instance in A.pack), the level would be the same as my DTS encodings.In Compressor 2.02 my 5.1 was 4 dB's to soft (looks like it went for -27 instead of -31) and my stereo way to loud.
Is there a way to install A.pack on a system with DVD studio Pro 4 installed?

I've seen one unconfirmed report that A.Pack would not work under QuickTime 7. However, I have A.Pack installed on my Tiger system (which uses QT7) and it seems to be okay. I've not tried any long audio encodings and under Tiger I have not yet burned a DVD with Dobly/AC-3 audio but A.Pack does run under my Tiger/QuickTime 7 setup.
Given that, I would expect that the files output from A.Pack would still work with DVDSP 4. However, I can't confirm that since I'm still using DVDSP 2.
In Compressor 2.02 ...
Where did you find Compressor 2.02? To the best of my knowledge the latest version of Compressor is 2.0.1.

Missing Audio in iDVD burns

Okay, I have seen several posts and suggestions on how to get the sound back on the dvd with iDVD, but nothing seems to work. I have tried EVERYTHING, except for the option that I am doing right now, but if that's how it has to work, I don't NEED itunes.
iMovie project, sounds great
exports to my iPOD just fine (with audio)
no audio when it reaches my DVD
Equipment used:
933 mhz PowerMac G4
LaCie DVD±RW Double Layer (which replaced my no longer compatible superdrive)
Plenty of Hard Drive space
maxed out 1.5GB Ram
OS X 10.4.8
I get the video, but no audio
I have already tried going into ADVANCE and clicking [Delete Encoded Assets]
I have also taken any Quicktime modifications off my computer (Flip 4 Mac)
I am now in the process of burning a Disc Image and testing it, with 933mhz, this takes a while.
Any other suggestions?
Thanks, and I know this is a frequent question, I just couldn't find the answer.

MacGreen:
I had a similar situation. There were 2 separate iMovie6 projects (both 16 bit audio) that were brought into a single iDVD6 project. When I mounted/viewed generated image file, one movie had audio and the other did not. Somehow audio was not included in encoded video files for the 2nd movie.
Problem might be related to fact that total size of encoded video files (in VIDEO_TS) was approaching limit of single sided DVD (4+ GB). I noticed that if I did trick of exporting/importing full DV in iMovie, then bringing back into iDVD, for some reason, the total size of encoded video files was now less that 4GB. Maybe that gave room for audio in 2nd movie.
Or maybe its not related. I did not have any missing audio problems like this using iMovie5/iDVD5 combo (and earlier versions) and I made a bunch of DVDs of varying sizes using those packages. Seems like a bug somewhere. I know you are using FCE. Can you export edited projects as DV and bring back into iMovie6 then into iDVD6?
Let us all know if you get your project working properly.
Good Luck.

How do you convert audio to ac3 in DVD SP 4 without a.pack

how do you convert audio to ac3 in DVD SP 4 without a.pack
thanks
Josh

NO. If you let DVDSP make your encoding you'll get uncompressed audio (AIFF/PCM) what means most probably high bitrate issues during building/playback and a lot of the space of your disc.

Video bit rate too high when try to build and burn. Audio is AC3

I am trying to burn a dual layer DVD and when I go to build/format the DVD it says that the video bit rate is too high. I am confused by this because this DVD was burned previously without a problem. Changes had to be made to the project and the files were compressed in compressor with the same settings and now they do not work. The audio is AC3 dolby. Is there some setting that needs to be changed in DVDSP? What am I missing here...
I am using FC Studio 2.
Thanks!
Natalie

I don't know exactly what the total length of the video is in minutes, but I do know that it is 6.8GB for a dual layer. Probably at least 3 hours. I don't know what the target bit rate is? Is what you are referring is to what the compression I used in compressor?
I am using the setting DVD Best Quality 150 minutes 3.7mbps for video and the AC3 for the audio.
I am recompressing all the videos again just in case there was a problem with one of the compressions. I don't understand why it isn't working this time when none of the settings or compression had changed.
Thanks!!

Why doesnt X-Fi have on-the-fly AC3 encodi

I dont understand why Creative didnt add on-the-fly AC3 encoding on the X-Fi - considering the cost of the card, and 5million transistors? Surely it could at least be done in Software (drivers) with a bit of help from the CPU?
HDA X-Mystique 7. Gold is only a $80 sound card and has a C-Media 8768 8channel chip that encodes all audio (stereo, games, DVD's, etc..) in the PC to Dolby Digital 7. and outputs it as SPDIF - no analog inputs, no confusing DigitalDIN connectors. Just one optical connector
http://www.nvnews.net/reviews/x-mystique/
And considering all creative cards have major PCI Latency problems on various PC's (my SBLi've cuts out when passthroughing AC3 via Digital TV Tuner software, yet my onboard realtek AC97 chip works perfectly - changed the PCI latencies with no luck), I think I'm totally losing faith in Creatives workmanship Message Edited by Anarchi on 0-24-2005 0:50 PM

Partly because Creative have their heads up their rear ends when it comes to using a digital connection. They're more concerned with analog and do very little with the digital out which Dolby Digital Li've uses. I'm sure most are aware that only the advantage of using the digital out on a sound card and having speakers capable of decoding dd and dts is for movie watching.
Other activities will be limited to stereo which is fine for me I don't need my other speakers around me outputting the same thing. I will however be purchasing a set of speakers without a decoder next time probably Klipschs because I have horrible problems playing dvds in Windows XP MCE 05 with the digital out on(Logitech Z-680 decoding the dd or dts stream).
I didn't have the problems before with my SB Audigy 2 zs, but after responding to my email I sent Creative thinks it's MCE which is hogwash. FYI my problems are out of sync audio/video and glitchy audio when playing dvds I have to sometimes rewind or use the skip chapter button to correct the audio.

Quiet audio with ac3

Is it just me or is my audio level reduced when compressing for DVD using the "DVD: Best Quality 90 Minutes"? Seems I had this issue with Encore and there was a fix for it, but I have no idea what I had to do to maintain audio levels.
Thanks.

To keep your audio levels while encoding to AC3 you must change the following settings in the preset:
- Compression preset: None
- Dialog Normalization: -31
Save the changes as a new preset and use it in the future.
Hope that helps !

H.264 export, randomly missing audio tracks

Came across a strange issue when exporting a 1080p timeline using the H.264 export option. The first export had some strange video flickering issue, but the audio was fine. So I re-exported and switched to CBR instead of 2 pass VBR. On the 2nd export, the footage looked fine but for some reason tracks 3 and 4 which contained background audio, were not in the exported file, just silence. The thing that concerns me is the only encoding option I changed was the bitrate, and going from VBR to CBR, everything else stayed the same in the 2 exports. I have no idea why Premiere would mysteriously drop 2 of my audio tracks. Has this happened to anyone else? This problem has happened to me before, both with the flickering and missing audio. I've tried the usual updating to current version of Premiere, clearing preferences, etc. and still running into this.

I work in Broadcasting and we use Quicktime HD 1080i h264 with no problems. Plus the file sizes are just amazing (Less than 100mg for a 30 seconds)

MPEG-2 option missing from Adobe Media Encoder (ver7.2.0.43)

Hi all,
Having an issue getting the MPEG-2 option for our Creative Cloud installation, specifically in Media Encoder's presets.
The following steps were recommended on another Adobe forum addressing this issue:
1.Uninstall Adobe Premiere Pro or the Creative Suite.
2.Run the cleanup script found here: http://www.adobe.com/support/contact/cscleanertool.html
3.Reinstall Adobe Premiere Pro or the Creative Suite.
4.Launch Adobe Premiere Pro.
5.When prompted for activation during launch, ensure that the computer is online and complete activation.
If the computer cannot be brought online, complete the offline activation during the first launch of the software. Do not choose to activate later.
6.After Activation, close and restart Adobe Premiere Pro.
We have been able to run through steps1 to 4, however the Activation option in #5 does not appear at all (must be activation is included as part of our CC license).
Without the option to deactivate/activate Premiere how can we go about getting the MPEG-2 option to appear?
Thanks again

Hi Jim,
I'm having the same problem of the mpeg 2 codecs missing from adobe media encoder. I have 2 computers and on both of them the mpeg 2 options for encoding have disappeared today. Can you please help?

Video- missing audio sound

missing audio content when I record video on ipad. Any ideas on how to fix?

Judyqw3-
Have you verified that your iPad microphone is working? One way would be to install the free Skype iPad App, which has an on-line audio test capability.
If the microphone is not working, contact Apple. If you can demonstrate the problem to the Apple Store Genius, you may get a new iPad on the spot.

Pro Tools Missing audio file message syndrom exists on Logic

I come from Pro tools and i am a bit traumatised by this fkn Pro Tools missing audio file message for those who know what i mean..
Is it something possible and frequent in logic when we work on a daily basis ?

No, you simply copy the entire project folder to a flash drive and bring it home. If you have included the audio files in the project folder, which logic does by default, logic will find them just fine at home. If it asks where they are, you just hit "search" and if they're there, If you've copied the song file to your drive without including the audio files ("pilot error") then the program can't find them. Often, I get protools sessions from clients with missing files. Sometimes the entire audio files folder is missing, but more often the missing files are out-takes that are no longer part of the arrangement, and were still in the audio file list of the song, but were not included in the folder when the project was copied and brought to me. How or why, I cannot tell you.
