Audio de-synch on importing?

I'm trying to digitize some VHS tapes and iMovie is the only capture program I've got, but after a few minutes the audio starts to fall away from the video. Is there some way to fix this?

If it makes any difference, I'm working with SLP tapes (6 hours).

IDVD lack of audio on 12 bit import

Lots of coasters, (looked at articles deleted encoded etc.) but no audio to iDVD. The forums and articles talk about sound synchro problems with 12 bit. To me, a complete lack of audio is not a "synch" issue. Is it a matter of semantics or will iDVD 6.01 simplly not encode 12 bit audio?

I don't think 12-bit audio would effect having no sound at all. As you said, it is a sync issue, so I suspect what you are experiencing is something else. But it brings up some questions...
1) Is the missing audio only with 12-bit audio? Can you hear the audio fine if you import 16-bit audio?
2) What are you importing from? Is this a DV format camcorder or are you by any chance trying to import MPEG files? Multiplexed audio can be an issue with iMovie.
3) Did you check the audio settings of project? On the bottom you don't have volume set to 0 or something like that?

Where has the "recordings" options gone in imovie for the iphone? It used to be listed under the audio tab in the import icon.

there is NO "reload" button under "customize"!
how do I get my toolbars set back to pre-firefox4?

I have an iMovie that I created 10 years ago. I found the disk and imported. Everything is there except the sound! I converted in Wondershare to MPV4 but still no sound. There is an audio clip that was imported from an analog video camera.

A small update to this issue....
I have been trawling the forums to find an answer but to no avail...
And... I've tried exporting and bouncing individual stems and the full session, either by muting all bar the stem or soloing the stem.....and still nothing.
Same problems.....everything is audible in audition but nothing plays on playback.
Since the 'prelisten' channel strip is Solo safe this would indicate that you have a track or channel strip soloed somewhere else, out of sight. Are the Mute buttons on your channel strips blinking?
To view all objects in your mixer, click the button. You may have to scroll sideways to check the whole mixer.

Variable bit rate audio assets cannot be imported

Extracted some ac3 files from personal content DVDs I authored and burned myself (using DVDSP) to make a compilation. When I try to import these 5.1 ac3 assets, DVDSP is refusing stating: "Variable bit rate audio assets cannot be imported." These ac3 files play fine in QuickTime and other programs that handle ac3 files.
Can anyone help?

Hi:
Please give us some info about the original movie/audio formats and what encoding presets you used in Compressor.

Audio not synching during publish

Hello everyone. I'm working in Captivate 4, (purchased, not
trial). I'm relatively new user, but have been working intensely
for about a month developing my tutorial.
My project previews correctly, (entire file is 117 slides, 9
minutes long.)
However, after publishing to an AVI file, the audio does not
match up with the video - the audio playback is slightly slower,
and after 2 minutes, has lapped the slide.
I tried different publish settings, but have not found
anything to work, although changing some settings have improved the
output somewhat.
Does anyone have any suggestions for me?
This file will be published on YouTube. This is a
demonstration video only.
My audio was developed using text to speech, (so no music
quality sound is required) and each slide has one audio file per
slide, (nothing embedded.)
Settings I chose were:
Video Format: MJPEG Compressor (tried Indeo, but syncing was
worse)
Audio: PCM (only choice)
Encoding: FM Radio (64) and 11.025 KHz Frequency
Encoding Speed 5
I restarted, and do not have any other program actively
running (except Kasperski)
We recently reformatted the hard drive on this machine, took
every program off, defragmented, so the system is very lean and
clean.
Added more memory, so now we have 3 GIG of memory.
Running XP, the only installed programs are MS Office,
Kasperski, and Captivate.
Any help would be greatly appreciated!
Thanks!

External Audio recording to be imported & used in FCE

Hi there,
I am thinking of using this audio interface to record some vocals. It is a Focusrite Saffire 6 USB. It comes with a software called Ableton Live that can record the sound in wav or aiff format.
http://www.focusrite.com/products/audiointerfaces/saffire_6usb
According to this spec, it uses a *24bit 96kHz a/d covertor*.
http://www.htfr.com/more-info/MR326826
+TECHNICAL SPECIFICATIONS:+
+2 channel USB audio & MIDI recording interface+
*+24bit 96kHz a/d & d/a converters+*
I am using a standard defintion miniDV tape video camera and in my FCE, in the Easy setup, I have selected DV-PAL 32kHZ Amorphic.
My question is, will the sound recorded using this Focusrite Saffire audio interface be imported into FCE4 for editing together to mix together with my video clips (recorded in my standard defintion video camera) ?
Thanks you.
Cheers

QUESTION 1:
I also discovered something strange when I check the settings of all the previous video & audio clips imported into FCE4. Those that imported in from video camera, the values are 16 bit 32 kHz (How come ? My video camera is set to 12 bit 32 kHz)
Despite the material is recorded in 32 bit, the capture process with 48kHz setting are allowed, but on long shot, you can expect a audio drift from video if sequence's audio is not the same as original sources.
QUESTION 2:
Then, I look into all the audio clips I bought from iTunes & imported into FCE4, they are all listed as 16 bit 48 kHz.
The funny thing is that both these type of different clips (ie, 16bit/32kHz & 16bit/48kHz) can be rendered without problem. How come ? FCE4 can mix clips of different audio types ?
BTW, importing iTune purchased song into FCE is prohibited by iTune EUA. Any non-natively supported media can be rendered in FCE, but as explained in question 1, you can expect audio drift on long clip. This problem is not relevant with music track audio which is it not part of a video footage.
QUESTION 3:
If I set the Ableton software output to 16bit 48 kHz, does that mean that I actually cannot make use of the hardware abilities to produce sound of 24 bit 96 kHz ? Is there much difference ?
96 kHz is used for professionnal multi-track audio editing. You have to use high-end audio monitors to ear the difference... if you can. Usually only audio engineers can ear the difference.
Audio CD use 44 kHz and the quality is pristine on hi-fi deck. 48 kHz is the standard in video production and even used in dolby 5.1 home theater configuration.
QUESTION 4:
In the Easy Setup, I cannot find 16 bit 48 kHz. I only have the following option in the Easy Setup of FCE4:
a) DV-PAL
b) DV-PAL 32 kHz
c) DV-PAL 32 kHz Anamorphic
d) DV-PAL 32 kHz Anamorphic Basic
e) DV-PAL 32 kHz FireWire Basic
f) DV-PAL Anamporphic
g) DV-PAL Anamorphic Basic
h) DV-PAL DV Convertor
i) DV-PAL FireWire Basic
So, which one do I chose ?
Use DV-PAL.

No audio on playback of imported mpg2 video clip while editing

I was assisted yesterday by your technical support team to install the photoshop elements 12 & premiere elements 12 which I purchased e few minutes prior.
while trying to work with the premiere elements 12, I realised that I have no audio on playback of imported mpg2 video clip while editing.
How can I solve this audio setting problem?

Audio wont play after importing from camcorder

I import video fine via the camcorder, the audio plays fine while importing but when I went to edit it, the audio track stops playing after about a mintue or two.
It shows up in the timeline, I have it checked to play, but for some reason it does not play, any ideas why this happens? I extracted a small clip of audio, and it still wont play. Any help is appreciated!

I'll double check at home the cam is there, I was messing with the settings at one point, new cam but don't think I changed any audio settings, just put it to stereo....

PE3 - Audio & Video out of synch on imported VOB files

I have tried adding some footage imported from DVD & is saved in a folder on the PC (by the PE process).
The file is stored as VOB 1 & VOB 2. When I import this file into the PE project the first half plays OK. When it plays onto the second file, the audio is lagging behind the video by a considerable amount.
If I view the file separately (where it is stored) with Windows Media Player, it plays back fine.
When I view the file in PE in the preview window, the out of synch fault occurs.
Something is happening in the import process to the PE project.
Anyone, have any ideas on the problem?

Here is a reply that I posted to a past thread that will give you options for fixing the Out-of-Sync issues when trying to use VOB files within PE.
In all cases it is better to not import VOB directly to PE, but convert to DV-AVI via one of these methods and then use the AVI format.
The last bullet below sends you to a Muvipix link describing how to combine multiple VOB's from one disc to a single file, this will cure the Sync problem, then convert this file to DV-AVI for import to PE:
I take the min-DVD directly from camcorder to my PC, and capture the disk via Power Director.
PD will convert the VOB's directly to DV-AVI Type 2 on one pass.
I then load this DV-AVI into PE7.
(PD v7 was pre-installed on my new PC from HP, or it can be purchased from Cyberlink).
Other options to try:
Copy the VOB's directly from the mini-DVD to your PC and use Prism to convert these to AVI.
Prism is a free convert utility and can be found here:
http://forums.adobe.com/thread/415317?tstart=0
Or load the VOB or Mpeg into PE, then use that to convert to AVI.
(Export to DV-AVI with PE8 is done with SHARE/PC, not Export under the File Menu, which is greyed out).
I've had many issues trying to work with Mpeg's and VOB's when loaded directly to PE with limited success.
So if you can get it converted successfully to AVI outside of PE, I've found this to be a better approach.
Post results, if any of this works for you...
Note: One other thing, if you are working directly with VOB's to PE, especially multiple VOB's from a single DVD, you can encounter out-of-sync issues between video and audio. If this occurs, review this link from Muvipix:

Audio and Video not synched on import

I am trying to import a video shot on a Canon XH-A1 in HDV. WHen I import it into IMovie in HDV it previews at 1/2-real time and the audio is off by 2-4 seconds. When I import it in DV it imports correctly with the sound being synched however I lose the definintion of HDV.... Can anyone help me, is this a Canon issue or an IMovie issue???? Thanks in advance..

Welcome to discussions, Prescottphotog
Have you tried importing the HDV to imovie, then saving, closing and relaunching imovie? It may be that the audio will be in sync once iMovie has had time to cache it properly.
That's a lot of information for it to take in.

Audio not in synch when importing from passthrough

I am trying to transfer some old home movies from VHS to DVD. I am using the passthrough on my Sony TRV-120 to connect the VCR to my Mac.
For some reason the audio is not synchronized with the video after import, however, when watching from the VHS tape it is fine.
Any help is appreciated.
My specs are as follows:
MacPro Quad Core 2.8 Ghz
FinalCut Pro Studio 2
OSX 10.5.4

I see this question on forums all the time and I see bonehead crap telling people to buy new hardware or software or other trivia. There are real-time, easily implemented things you can do that will fix the problem, immediately and without fail
1. Convert small as small a chunk as you can at a time. If its a concert, do it one song at a time. If a tv show, go commercial to commercial. The shorter the chunk, the less frames dropped and the less lag time and potential for getting really out of synch.
2. This is the most important factor: frame rate. The most likely reason you are getting out of synch is that your computer is not fast enough to keep up with the frame rate. Most set the rate at 30fps. Try tweaking it down to 20, then watch how many frames you drop as it's converting: most decent conversion software has a read-out telling you. I use Blaze Media Pro myself. If you are getting almost no dropped frames, you can probably bump it up some, if still too many, knock it down a little. There is very little noticeable difference in 15 to 30 fps, in fact, if you plan on uploading it to YouTube or otherwise converting it, the framerate is going to be sharply reduced anyway.
This is an almost foolproof way to avoid video/audio synching problems when converting from VHS. I took the time to post this because I was tired of seeing all the useless advice posted on this subject.
Video editing and conversion takes a lot of CPU power. If you really intend on getting into it in a big way, you'll need a strong CPU capable of handling the load. Other than that, framerate is probably your best bet in making do with what you have.

Import audio and synch to screencast?

I inherited (and have been asked to fix) a Captivate presentation whose audio quality is dreadful. I do not want to re-record the screencast, I'd just like to re-record it in synch with whats on the screen. Is that possible? Conversely, can I import audio and somehow modify the screencast to synch up with the audio?
I am new to captivate.
Best,
Janet

That depends largely on how the original recording was done. If it was done screen capture by screen capture with added objects such as captions, text entry boxes etc. Then it should be reasonably simple to add new voiceover audio and time the elements to sync with it.
However, if the original capture was video demo or full motion recording (FMR) then you can't do a lot about the sequencing of the actions.
