Converting 30 FPS audio to 29.97 FPS audio in Audition or Premiere?

I recently shot a wedding using 7 video sources. Unfortunately the sound guy wasn't really the sound guy so after I set up my camera and checked the board audio he started playing around and surprise... my booth camera didn't get any soundboard audio. The only decent audio I got was from an iPhone I put in front of the speakers to get a specific shot.
Problem is the iPhone shoots at 30 FPS not 29.97. So when I try to edit, the sound doesn't sync correctly with the 29.97 footage.
I've tried playing with the speed in Premiere but continue to have sync issues later in the video. I started to manually go in and remove small clips from the audio timeline in Premiere to manually sync the audio but this is crazy for a 90 minute video.
Is there a way to convert the iPhone 30 fps audio to 29.97 audio in Audition or Premiere?

I had high hopes for Audition's Automatic Speech Alignment... but the audio is 48 minutes. Audition says I don't have enough memory even though I have 64GB of ram and over a 900 gb of free space on my cache drive. The only way it works is if I break into smaller clips less than 5 minutes each which is basically the same as me doing it manually in Premiere.
To other replies - yes I took the audio out separately to a .wav file and imported by itself. Still have the same sync issue. I thought for a brief minute that the sampling rate was the problem (41000 Hz vs 48000 Hz) or the bitrate (16 bit vs 32 bit) but when I corrected it so all were the same, it still has the same sync issue. I must be missing something really simple and on any other day would be obvious.
Guess I'll just go back and edit manually - there are enough silent moments to razor and shift the audio but it shouldn't be this difficult to fix what has to be a somewhat common issue.

VOB converted to AVI audio files imported to premiere play in different order than the video files

Hello there,
I extracted the VOB files from a burned dvd created with Adobe Premiere pro 1.5, I converted the files into AVI files, then I imported it to Premiere CS4. The video sequence on the timeline plays in the correct order but a very fast speed, and the audio sequence plays all the individual clips in a random order, not in the order that they were originally edited in.
What did I do wrong while importing or converting?
Elio38

Hi Elio,
What program, or utility did you use to convert the .vob files to .avi, and what was your target codec? I typically use SUPER Converter, which is free and very versatile, to convert program stream .vob files to a useable format that PPCS4 is compatible with. You can also directly import and edit a .vob file from a DVD in PPCS4 by simply changing the file extension to .mpg. However, doing so will eliminate the audio channel from the video clip in PPCS4.
I was able to recreate what I believe was your issue when I tried converting a .vob file to an .avi file, regardless of what codec I used. I had no issues what so ever when converting the .vob file to a .mov file using the DV codec, for example. It could be a bug with PPCS4 because the same .avi file I created with the DV codec played back fine in WMPlayer, and VLC, but played back almost in slow motion in PPCS4. It might be advantageous for you in the meantime to re-convert the .vob files to .mov files and just choose the standard DV codec.
Remember, you are trying to edit files that are intended for delivery and that were not originally designed to be edited. Attempting to edit inter-frame formats such as MPEG-2, MPEG-4, FLV, etc...has caused many a headache and even today, are not the easiest to work with.

Bad Header error importing Audio from Audition to Premiere Pro

Hey guys,
I'm not sure if anyone is experiencing a problem like this below, but recently, I have been up in arms trying to export a 90-minute feature film's audio (Ch. 1=Dialogue - Ch. 2=M+E - 5.1 Surround Mix) in a .wav file format, and every time I try to export it out, it PLAYS in Quicktime player, but it WON'T import into Premiere Pro (citing BAD HEADER ERROR) in file. I basically tried to utilize every file format there is for audio and such, but nothing is working (including .aif, but it kept cutting out at 13mins into the show). I separated the dialogue music and sfx in 3 submixes, but I needed to combine the Music and Submix into 1 submix to have ONE DIALOGUE Submix, and ONE M+E submix for our distributors. Any help to fix this would be great.

Paul,
Sorry to hear about the PC -> Mac problem. Old 6.5 Mac Project opened fine in CS2 PC, after I added the file extensions.
As for the AVI, Curt is correct. There should be a utility for the Mac, like G-Spot, which will tell you everything about your AVI file. Unfortunatly, I do not know if G-Spot is ported for the Mac (www.headbands.com/gspot), so you might need to find similar for you platform. You can then identify the necessary CODEC and install it.
Last, you should be able to find an edit-shop that has CS3 on PC and get them to Import the old Project, then Export it in CS3, so you can open it on your Mac. If not a commercial shop, then maybe a friend with CS3 on PC? Next best thing might be to find a Mac with Premiere 6/6.5 (last Mac version, prior to CS3 ?) and try that route.
Good luck,
Hunt

Levels of audio drops (audition to premiere to final video)

Ok, I export from Premiere to Audition. Mix there and set the peaks to -6db.
When re-export to Premiere the peaks change to -9db.
And when export for final product (and mp4 file) the peaks change again to -12db.
So I am loosing 3db in every export.
Did anyone have this problem and found an explanation / solution?
thanks

"A Bars & Tone Clip in the Source Monitor displays XXdB in the Levels meter.
Same Clip displays XXdB-3dB from the Timeline in the levels meter."
Yes.
But I found what is wrong. My sequence is DNxHD 220x. That I chose to use the previews in export. And the audio tracks in this option are set by default in mono 48Hz and 16bits. And I have stereo 48Hz 32bits. Now I made a new sequence this time changing mono for standard and the problem disappeared.
A silly mistake on my part.
Thank you very much for the help.

Convert video to audio only

I'm looking to play video podcasts (classroom lectures) on my Nano6g - even as audio only.
My university classes (U. Florida) come as a podcast which Itunes puts in the Movies folder rather than the Podcast or ItunesU folder, perhaps because of the file format. I've tried to copy the files into other folders but that doesn't work.
Is there a way in Itunes 10 to convert these to audio only tracks?
It really ***** that my 5g had this functionality but now I have to carry my Classic and my Nano 6G to do what the 5G could.

Not in iTunes, ditto for QuickTime.
but I bet a google search would point you to some applications that can do it.
And you might check, some podcasts have both versions: video and audio.

How do i convert to acc audio files

How do i convert to acc audio files

Hello Red Teddy,
The following article contains steps for converting content from one format to another.
iTunes: How to convert a song to a different file format
http://support.apple.com/kb/HT1550
To convert a song's file format:
Open iTunes Preferences.
Windows: Choose Edit > Preferences.
Mac: Choose iTunes > Preferences.
Click the General button, then click the Importing Settings button in the second section of the window.
From the Import Using pop-up menu, choose the encoding format that you want to convert the song to, then click OK to save the settings.
Select one or more songs in your library, then from the Advanced menu, choose one of the following (The menu item changes to show what's selected in your Importing preferences):
Create MP3 version
Create AAC version
Create AIFF version
Create WAV version
Create Apple Lossless version
If you haven't imported some songs into iTunes yet, you can import and convert them at the same time. This will create a converted copy of the file in your iTunes Library based on your iTunes preferences. To convert all the songs in a folder or on a disk, hold down the Option key (Mac) or Shift key (Windows) and choose Advanced > ConvertImport preference setting. The Import preference setting will match what you chose in step 3. iTunes will prompt you for the location of the folder or disk you want to import and convert. All the songs in the folder or on the disk will be converted. Note: Some purchased songs are encoded using a protected AAC format that prevents them from being converted. iTunes Plus purchases are not protected and can be converted.
The song in its original format and the newly converted song appear in your library.
Cheers,
Allen

Converting 2 channel audio from AVCHD to 5.1 audio for bluray

Hello,
I am looking to put AVCHD video files (*.MTS) containing 5.1 audio and 2-channel (stereo) audio onto bluray. I would like to convert the 2 channel audio to 5.1 audio, so that all of the files can be encoded onto bluray with 5.1 audio in Encore. I am using Premiere Pro CS6 version 6.0.3. I have tried to bring the MTS files into Premiere Pro, and convert stereo audio to 5.1 using Audition. However when the file is exported to Encore, upon transcoding there is no audio. Please let me know what is the best way to resolve this. Also, would I require something like Surcode plugin, or are there other ways to get around this? Thanks.

"Hi seaspray07,
"Hope this clarifies."
sorry it doesn't - it confuses me and I don't get why you want to do it this complicated way ;-)
1. If you have problems try to simplify your workflow. Why do you try to work with dynamic link in Encore? This isn't the classic route and I don't see why you need it in this case.
2. In a classical workflow you load final encoded audio and video files in Encore - in this case a .m4v and a .ac3 file encoded in Adobe Media Encoder.
3. To get this files you create a Premiere timeline with 5.1 master audio and load your clips onto it.
For all 5.1 clips Premiere will create a 5.1 audio track. For all stereo clips Premiere will create a stereo audio rack.
--> Keep in Mind you can't export a premiere audio track. That isn't possible even though this would be handy in a lot of situations. You alway only export the master audio track of a timeline. That master audio track get's it input from all audio tracks of a timeline. If there is a 5.1 audio track 6 channes are mixed to the master audio - if it's only a stereo track only L, R get's mixed up to the 5.1 master.
The master audio track is what you can hear if you play back a timeline.
4. Why do you want to convert stereo audio tracks into 5.1 audio tracks in the timeline? It needs much more filesize/ ram slows down your playback and gives you a unhandy viewing with lots of emty audio channels... Why dont store and view a stereo track as a stereo track?
5. If you have placed your stereo and 5.1 audio tracks on the timeline you can export the final mix via Adobe Media Encoder with the Surcode plugin as Dolby Digital 5.1 .ac3
"I sent the audio to Audition because I wanted to modify the audio file from stereo to 5.1, and bring it back into PrPro to combine with the video clip from the corresponding MTS file..."
That doesn't make any sense... because Premiere does it automatically for you without Audition. You simply have to do nothing - just place your stereo clip on the timeline and ready.
If you want to use Audition you have to have a real reason for it - for example do extensive audio work and mastering Tasks - conform it to R128 loudness or something like that.
Does this make sense to you? ;-)

I How to block iTunes option to auto convert in predetermined audio player

My PC have OS Windows XP and I use for years Windows Media Player and Media Player Classic to play my music and video files, so I know quite well their operation and all their options. The naughy problem is that every time when I connect the iPod to my PC or if I open iTunes automatically iTunes auto convert in the predetermined audio player without any advice or previous authorization, an also change the extension configuration of my favorite music players. This changes force me each time to uncheck the audio option of iTunes and reconfigurate the extensions configuration of my favorite players so I can use them as always to play the audio files.
My question is: What I can do to block definitively the option of iTunes to auto convert as predetermined audio player ,except the option is activated manually.
Thanks for any help.

You should be able to take care of this problem with your Windows XP settings.
Right-click the CD Drive in Windows Explorer, select Properties, go to the AutoPlay tab, select Audio CD in the drop-down menu and then choose the appropriate option from the Actions commands.

Converting an AVI/ Audio out of sinc

I need to use this clip and every time I try to convert it the audio is out of sinc. It's completely in sinc in the original format, which QT plays just fine. I know I might be able to use it without converting it. But I don't want to chance it. The original format is: Generic MPEG-4, 608 x 336, Unknown
MPEG Layer 3, Stereo, 48.000 kHz
I've used QT's export feature for an MP4, I've used DivX Doctor II, I've even used iSquint. All resulting in out of sinc sound. Any suggestions?

mpeg streamclip didn't work. Could it have something to do with the computer the file was made on? I think it was a PC. I know it was a rip from a dvd. But the only thing I can think of is some issue with a codec or two. This project is due in a couple of days! Any more suggestions?

Converting left channel audio into stereo file

I'm using an edirol ua 25 which has two inputs, 1 which is a left channel and 2 a right channel. As i'm using the first input, the recorded audio pans hard left, how do I go about converting the recorded audio into a central stereo file?

Why do you want to change it to stereo? It isn't a stereo (two-channel) recording, it's a mono, single-channel recording.
Mono is not somehow "worse" than stereo, don't feel that need that everything should be recorded to two channels, it's a waste of resources.
You can pan it anywhere in the stereo field - with the pan knob central, the mono track will be centered in the stereo field. You can pan it left or right accordingly.

Panasonic .MOV files only play audio no video in Premiere Elements 11??? Not Working Help

Panasonic .MOV files only play audio no video in Premiere Elements 11??? Not Working Help

It all depends on the codec the file uses, Karli.
What model of camcorder is this video coming from?
Are you working on a Mac or a PC? Have you got the latest version of Quicktime, per the program requirements? When you started your project, did you select the settings for a DSLR at 720p? This is a vital step since it will activate the components your computer will need to work with many of these types of files.
BY THE WAY, KARLI--
PLEASE do not post the same question more than once on this forum! You've already got a thread going with this same question and several responses posted. It's very confusing when you post the same question a second time and start a whole new discussion.

How do I get audio back on single clip that loses audio when imported into Premiere Pro CC?

I've got one clip out of many that for some reason won't play any audio when imported into Premiere Pro. I am new to Premiere Pro so am hoping it's something stupid I've done, but this is a problem with just a single clip exported the same way as all my others, the original audio is loud (not quiet) and none of the FAQ issues seem to apply (ie I haven't muted the audio or anything stupid like that)
The clip was exported from Plural Eyes into a "master" Premiere Pro project where the audio is fine. I exported it as a short MP4 clip and if I play the clip in Windows Media Player the audio is there loud and clear.
But when I import the clip into a fresh Preimiere Pro CC project this clip appears with just the "film strip" icon on the far left in the Timeline panel, unlike other clips which have an icon that shows "film strip" in the background and "audio wave" in the foreground.
I'm hitting so many glitches with the CC editions of Premiere Pro and After Effects which have annoying inconsistencies between them I'm tempted to just go back to Sony Vegas Pro (single program, no hassle) but hoping most of these issues are down to "newbie incompetence". Very hard to understand why this one clip out of many should be giving me this specific problem though. Any ideas?

I'm getting so many weird results. Most go away by simply closing the project and re-opening and I only have 6GB memory but even so, I'm disappointed by what I thought was supposed to be more "world class" video editing software than Sony Vegas Pro which I found to be a lot more stable. Also struggling with differences between Premiere and After Effects. Every time I want to do something in Pro I seem to need to go to After Effects and vice-versa. After Effects lets me do more of what I could "just do" in Vegas Pro timeline, but it's hideous for lining up audio and having to render anything in RAM to even get a clue as to what a change has done. Need to add Audition to the long list as well I suspect. Fun times!

Errors Sending Audio to Audition

The Issue
Selecting "Edit > Edit in Adobe Audition" from within B Video composition (which contains a video file) while in B Frame composition (which contains B Video composition) results in the following errors:
After Effects can't continue: damaged i/o structure.
( 39 :: 113 )
[OK]
=====
Clicking ok then says
=====
Before quitting, you have one chance to save your project (don't use the same
name as the original).
[OK]
=====
Which is quite terrifying
=====
Choosing to save or hitting cancel results in the application closing.
What I was trying to do
I'm just trying to send some audio to Audition for editing. I did it once and it brought over my in and out points based on how I cropped it, which was perfect. Doing it a second time on another video however, did not bring over the in and out points but the audio for the entire video file. What am I missing?

Well that explains the bug portion of my post, but in getting around that (doing it properly). I don't think AfterEffects imploding is the best way to inform the user that that's now how it should be done.
That said, doing it properly, I'm not getting the results I'm looking for. I'm not getting the in and out points of my video despite sending the cropped version of the video.
