Synching video with external audio source

We shot an interview, and somehow no audio was recorded...no worries, we had a little digital recorder going as a backup....
I synched the video with the audio, and all is good for about 10 seconds, but then, sure enough, the audio begins to go out of synch,...
I suspect this has to do with the whole 29.97 vs 30 fps issue, i did play around a bit, but couldn't figure it out...
any suggestions?
the video is regular DV...
audio is 32hrz WAV (converted to 48 hrtz AIFF, no help)
anyone?

This is a problem that comes up regularly around here so try searching.
The clips must be different lengths, yes?
The audio clip may be the same length but it must be clipped off.
The way I have dealt with this on a friend's system (using a Canon XL1 as the DV input) was to simply open the Speed window of the of the audio clip and enter a new time so it precisely matched the time of the video clip.
Say the event is exactly 60 seconds long from first frame to last frame. The audio drifts out of sync so it is slightly longer, say, 61 seconds. You control-click on the audio clip in the timeline and enter a new length. It may need to render.
sorry not to have the absolute answer. Double-system sound just doesn't come up very often in my life. Luck, let us know.

Is there any way i can record a video with 2 audio sources?

I want to be able to record a video with 2 audio sources (1 being a mic and the other being a guitar, both plugged in by usb's) while recording myself playing at the same time. I usually use an aucoustic but the sound is obviously much better when i plug straight in, is there any way i can do this without recording everything seperate? Im using a macbook pro.

Are you looking to do post recording adjustments to the separate tracks? That really determines now you do this.
If you not looking for multitrack recording (you just want to combine the two signal into one and record that) then probably the easiest thing to do would be to get an external mixer that would accept multiple inputs and output as USB . Then you could set the levels with the mixer and just worry about recording the one signal.
You could try using the MIDI Audio Setup app to create an aggregate device (one that will accept multiple inputs).
There is also the 3rd party app Soundflower. It's an app that takes audio signals and allows you to route them between apps and to combine audio signals. It is dated but still works in 10.8

How do I import AVI video with stereo audio (and keep it that way)?

Today I just discovered that all the AVI video with stereo audio I've ever imported into a Premiere Pro CS6 project has been mysteriously converted to mono. And I can't find any import setting anywhere that enable me to change this.
Here's the deal...
I've have an AVI file with stereo audio (the file is actually a stereo sound test that I downloaded to prove that I wasn't imagining things). On my hard drive, I right-click and view the properties:
Video
Length: 00:00:36
Frame width: 320
Frame height: 240
Frame rate: 25 frames/second
Audio
Bit rate: 128kbps
Channels: 2 (stereo)
Audio sample rate: 44 kHz
I click on it to play and listen with headphones--everything is playing in the correct part of the stereo spectrum. Then, I import it to Premiere, click the file name in the left content menu, and check the properties, suddenly they read:
Type: AVI Movie
File Size: 1.1 MB
Image Size: 320 x 240
Frame Rate: 25.00
Source Audio Format: 11025 Hz - 16 bit - Mono
Project Audio Format: 11025 Hz - 32 bit floating point - Mono
Total Duration: 00:00:36:15
Pixel Aspect Ratio: 1.0
Sure enough, I drag it into the sequence, listen to it, and it's indeed playing mono. Outside of Premiere, the original source file still reads and plays correctly with stereo sound.
When I import stereo WAVs and MP3s, it keeps the original stereo channels without me having to do anything special. I even just imported the same exact file as a MOV with stereo audio, and it showed up in Premiere as:
Source Audio Format: 44100 Hz - 16 bit - Stereo
Project Audio Format: 44100 Hz - 32 bit floating point - Stereo
What is going on here with AVIs? Am I doing something wrong? Are there settings I'm missing somewhere?
(And before anyone suggests I only use MOV in the future... that's not exactly the answer I'm looking for.)

Thank you for that info.
For video, the codec is MPEG-4 Video (XVID) and for audio it says MPEG Audio Layer 1/2/3 (mpga).
There are two issues with that file:
The first is the Xvid CODEC (not meant for editing), and then the MPEG Audio/MPGA. I would convert that file, to something that is more editable.
Good luck,
Hunt

Can I select an external audio source?

I have iMovie09 ver 8.0.6. I'm using a Panasonic video camera (it uses miniDV tapes) connected to my MacBook (white plastic 07) via firewire. When I have the cable from the mixer going into the camera and recording to tape; when I transfer the tape to MacBook, I get the external audio source great!!! However, when I plug the cable directly into the MacBook, it still gives me the audio (BUT) from the built-in mic of the camera. When I open GarabeBand and record the audio, its the external and its great. However, I don't want to have both recording at the same time only to overlay the GarageBand audio onto the video clip. Yes, I've selected the 'in-line' option from 'System Preferences'.
Is there a way that I can select the external source while in iMovie?? Looking at some other negative posts, I don't want to upgrade to iMovie 11 either.

I came across a much older post which I believe solved my issue. I connected everything up first, then booted up the MacBook; then I selected 'built-in audio' from the 'voice-over' option within iMovie. It recognized it right immediately. However, now I'm not sure that the audio is in fact coming from the 'hot' microphones that I'm receiving from the mixer. But that's just troubleshooting.

Why video with two audio tracks imports like one track (main)?

Ok, lets face one simple thing that is incredibly stupid in Premiere CC:
- I make video with two audio tracks (screencast with system sounds and microphone, separated)
- Import it to Premiere CC and see only one audio track, system sounds!
- What should I do to see both of them?
- Why Sony Vegas don't make me to go to support forums and make them both visible without extra actoins?

Great first post!
Ok, lets face one simple thing that is incredibly stupid in Premiere CC:
Channel Map the Audio to do what you want it to do with t e source clip.

You could have read the Premiere Manual or watched the Adobe TV Tutorials or gone to edit school instead ...

Equium L20-197: No line-in jack - How to record from an external audio source

Hi,
I'm generally very pleased with my Equium L20, but am now finding a few annoyances that I guess are cost-cutting issues. For instance, there's no onboard mic, so need to buy one for Voip purposes. And I would like to use this laptop to record from an external audio source, but now discover that there is no line-in jack, and it seems the microphone jack is mono only, even if it was possible to configure the audo card to use this for line-in source.
I'd be very grateful if anyone has any ideas for a workaround perhaps using a USB port.
TIA
Keith

Hi R2D2,
Thanks for your quick reply - it set me on the right track and I've been googling for similar solutions available in the UK. I've since found this product - http://www.dolphinmusic.co.uk/page/shop/flypage/product_id/9326 and redhawk has pointed me at something by Creative Labs which I'll try and track down.

I have new hard drive in macbook pro(08) and have SATA cable with external power source to old hard drive (10.5.8)via. USB port and newer drive(10.6.8) will not recognize older drive..Do I need to partition newer drive with older disk to recover data?

I have new HD 750GB Hybrid in 2008 Macbook Pro 17" w/ Snow Leopard 10.6.8 connected to old Hard drive(250GB that had 10.5.8 on it at time of failure) via SATA cable to USB port with external power source.. Computer not acknowledging old HD at all in Disk Utility or otherwise (that I'm aware of)..Do I need to partition New HD and load old(10.5.8) onto partition to recognize older drive for data recovery? Thanks Wayno08

You do not need to load 10.5.8 onto your new drive in order for a 10.6.8 system to see the contents of a 10.5.8 system.
You might want to check out the hard drive troubleshooting bootk in the downloads section of this web site:
http://scsc-online.com
They also sell a product named Phoenix that can do OS extraction and volume copying/cloning, but to be honest I don't know if it's appropriate in this case.
I would suggest the following:
Open up Terminal.app (under utilities) and type "diskutil list" without the quotes. This is the command line version of Disk Utility. If the external drive doesn't show up at all, then it's likely not connected properly, not getting power, or just plain dead. If it shows up with only a devce name like disk0s16 but no volume it means the drive is seen, the OS just can't make sense of it.
Assuming the drive shows up, I would try to boot off the original installl disks for the system and run Disk Utility from that. I'm assuming the drive will show up. You'll want to select the option to repair the drive and then perform the option to repair the permissions.
If the unit isn't showing up, as per step 1, try a different USB port. More importantly with your unit, try it on another side of the unit if possible. If you read the book I referenced above, some of those units have I/O boards that are separated from the logic board. If the cable from the logic board to the I/O card goes bad or has problems, which isn't all that uncommon, some or all of the ports on the I/O card may appear to be bad as well. If you use a USB port on another side, it would be routing out of a completely different I/O path, so that's a potential problem.
If the drive is only seen with a device name such as disk0s16, it's likely either the index files are corrupt beyond Disk Utility's ability to see them. The only thing that I think would help would be a product named DIsk Warrior, but I can't guarantee that.
Disk Warrior can be found at:
http://www.alsoft.com/diskwarrior/
The company that I linked in the first link above also makes a product named Scannerz that does HD and system testing. The Scannerz/Disk Warrior combination make a good pair because the complement each other....Scannerz does what Disk Warriror can't and Disk Warrior does what Scannerz can't. However, at this point I'm not too sure getting a tool like Scannerz would be of much use because it sounds like the damage has already been done.
Let us know what happens.

SPM : Integration with External Data Sources

Dear Experts,
Can you let me know with your comments or by sharing any link or documentation, as to how to Integrate SPM with External Data Sources.
And how many or what all external Data Sources, can SPM Connect with ?
Regards
Pankaj

Hi Pankaj,
There are no limitations of external data you can bring into BW and visualise in the SPM UI - you can expose custom bex queries as "datasources" in the user interface, and these can show anything you like. Its just a question about what makes sense to show in SPM.
Are you looking to bring in anything specific?
Thanks

Video with Multiple Audio Tracks-- IOS 4.2 Removes Way to Select Them

After upgrading to IOS 4.2 on my iPhone 4, I've found it no longer lets me select from among multiple audio tracks. The option and button is completely gone.
I encode my videos with AC3 audio as the first track (for my home media devices), and stereo audio as the second track (for the iPhone). Now the iPhone will just play the video, with no audio, and no way to select another track. This is extremely frustrating as I've encoded all my DVDs this way, and never had any issue with playback like this on any IOS device going back to the first gen iPod Touch.
Anyone else have this issue, and know of a work around? Thanks!

I too have the exact same problem for the exact same reason. Did you ever figure out a workaround (other than reencoding all your videos)?

Broadcasting MPEG 2 video with multichannel audio

Dear sir
Using PrPro 2 or CS4 I want to export MPEG 2 video with multichannel audio ( 2 separated stereo channels ) for broadcasting purposes .
As you know there are some TV channels that allows you to switch between two audio tracks , which I am looking to accomplish
This is some of specifications that I use for video production :
1. Primer DV PAL preset .
2. AVI format
3. Canopus Grass Valley ProCoder 3 ( to convert video from AVI to MPEG 2 ) according to the Broadcasting standers .
As you see I'm not able to separate the 2 Audio tracks when I try to export the video file.
So If you have specific method or steps to apply ( 2 separated stereo channels ) for one video file , please be kind to inform me with it .
also please let me know if I missed any details .
Best wishes

Very very very nice that is all what I am asking for .
I tried and it worked perfectly but the file has a .VOB extinction … I changed it to .mpg and now I can play it in Windows Media Player too .
Ok , so far so good, your advise was very helpful so thank you very much but what abut broadcasting ? is it going to mach the broadcasting standers ?
I know.. these are lots of stupid questions but I am asking if you know any thing about it or some resources that can be used.
When I converted it using The ( Procoder ) to mach the broadcasting standers I got only one audio track .
I appreciate the generosity and your attention .
Best wishes

Synching External Audio Source. TC In/Out of Camera?

A guy I know wants to record 6 seperate channles of audio on an external deck and somehow have it synched with timecode to the video on his camera. The camera is an HVX200. Is there a way to get the timecode of the video to match the timecode of the audio so it's easy to synch in FCP?
What kind of equipment is needed for this. Is it audio side or video side that generates the code?
I'm not so up on my external audio. Thanks in advance.

What was the question?
Your choice of recording system is critical, you'll need timecode and RS232 or 422 control. Suggest you find an FCP operator locally who has had success with mutlitrack sources.
If you have more specific questions, post 'em.
page 294 of volume 1:
Capturing Audio From an Audio Deck Using Device Control
Final Cut Pro allows you to capture audio from a device-controllable audio deck such as
a professional DAT (digital audio tape) decks or a digital multitrack recorder. This is
mainly useful when capturing audio that was acquired via dual system recording, in
which video and audio were recorded simultaneously to different devices.
As with capturing video, your audio tapes must have timecode recorded on them or
you cannot set In and Out points for capture. Audio decks may be controllable if they
use one of the standard device control protocols (typically, RS-422) supported by
Final Cut Pro.
If you’re planning to capture dual system audio using device control, make sure that your
audio deck is genlocked with the audio or video interface you are using for capture. For
more information on connecting a device-controllable audio deck to your computer, see
“Connecting Audio Devices” on page 204. For more information on capturing
synchronized audio, see Volume IV, Chapter 24, “Capture Settings and Presets.”
page 296:
If you are editing material acquired via dual system recording, meaning that video and
audio are recorded simultaneously to different devices, you need to capture your audio
and video separately and then synchronize them together in Final Cut Pro. After
capturing, you can combine the corresponding video and audio clips into a merged
clip. Merged clips work in the same way as other clips in Final Cut Pro, but they refer to
separate video and audio media files (whereas most other clips, such as clips captured
from DV tape, refer only to a single media file that contains both video and audio). For
more information about merged clips, see Volume II, Chapter 3, “Merging Clips From
Dual System Video and Audio.”

Export Video with Multiple Audio Tracks

I need to be able to export video with audio on multiple tracks. I have moved to CS6 from FCP 7 where this was rather easy to do. I can make a preset in AME with more than enough mono tracks but after the encode the video is always smashed to one mono track. I am not doing a 5.1 mix, there are different mic's on each track that need to remain independant of one another and mixing them down within Premiere is not feasable. Are there no options to just have the audio 'pass through' like Compressor? Sorry if there are other posts but I have been searching forever and can not find a simple answer on this topic.
Also, is there no way to have the source timecode burn in? Putting a filter on the video in a sequence is unacceptable, I am very displeased to find that this doesn's seem possible in AME or Premiere, it has been part of Apple's suite for years.
Example of my preset from Compressor:

Hi James,
For exporting a multitrack .wav file, you have to start a project with a multichannel audiomaster (3-16 tracks).
Copy and paste your complete edit to the new editsetting.
Now in the audiomixer you can route your audiolayers to the multichannel you like.
(CH1+2 pan to left is channel 1, pan to right is channel 2 and for a stereo track pan to center : channel 1 for left and channel 2 for right.)
Then you export your project to a 3-16 tracks multitrack .wav file.
When you need mono tracks you can import your multitrack .wav file in premiere. Then send it to Audition (edit in Audition) and then adobe will convert the file into mono tracks.
You'll find the mono tracks in your audio capture folder or can premiere search for then by 'reveal in explorer'.
The multi track .wav file has got timecode within the file.
When exporting in QT you can also choose for a multitrack audio file. It also contains your timeline timecode.
.avi or .mp4 video files cannot be exported with more than 5.1 channels of audio
MXF OP1a in XDCAMHD can also be exported with max. 16 channels of audio. It also contains your timeline timecode.
Hopefully you can get further with Premiere Pro with this info.
Succes with it!!

Locking / Grouping Video and External Audio

I have video I recorded and it's in my timeline.
I have audio I recorded from my DAW and mixed down to a stereo mix (for a music video) and I've synced them up via a sync point.
When I grab the video file, I want the audio to move with it ... for them to be locked or grouped. I tried to "LOCK" them together but it's not working.
What am I doing wrong?

2 things ...
1. Even when I drag the video file (which still has audio from the camera for syncing purposes) into the timeline, the audio in that video file won't LINK correctly. Meaning, even when I press CMD L it will underline the clips name as if it were "locked" but if I click and drag just the video clip, the audio won't drag with it. When I splice the video file, the audio won't splice with it. What's interesting is that FCP used to do this with older projects I was working on but maybe I hit a setting that somehow altered this feature?
2. I'm creating multiclips from 2 camera angles, the "LINK" feature is greyed out when I want to "LINK" the multiclip and the external audio I've mixed down in ProTools. It's not even an option to select when I highlite my multiclip and my external audio.
Re: Studio X, I appreciate the suggestion ... but TBH I'm not a video expert and not sure what "nesting" is. I just googled it. What I've done is created a multiclip using my SYNC IN POINTS I created and now I want to edit/cut this piece together. I still have color correction and things to do so "nesting" might be a bit premature for my abilities at this point.
any other thoughts on why the audio/video aren't linking correctly and how I can get EDITS and MOVING clips to happen together with just one mouse click?

Final Cut 7 audio sync issue with external audio

Ok, I've seached around a lot and still haven't found the solution for this common issue, which is sync between video and audio wich were recorded in two different devices.
My video is from a conference (a lady speaking all the time) ProRess 29.97 and my audio is wav recorded at 44.1 Khz. I have already converted my external audio to a fine AIFF 48 Khz, and I have already re-imported it with the correct 29.97 easy setup, as it shows on this video www.youtube.com/watch?v=Nt-nfelM8KA. That helped a lot but audio still goes out on sync when playback goes further (not that much, but it shows).
On Premiere Pro, that wav file a correctly in sync, and I have had this issue before with FCP and now it has come back! help!
Anyone found a real solution for this issue?

Why not just use Premier? FCP is going to slowly die out anyways....
Anyhow, a work around... using the speed change tool (sss) adjust the audio to be the same length of the video so it is in sync... Press command-J, make note of the percentage you sped up your audio. Now open your audio in STP, select all of your audio go to Process>Timestretch and adjust the audio and apply the same percentage.
Listen to your audio. STP's time stretch is excellent because it adjusts the speed without changing the pitch.
Save as, re-import your audio.
