Audio rate 47.928 problem

Hello,
I'm importing some VHS tapes via the DAC-200 but the audio is not in sync. Especially when I capture large clips. I found the cause: the audio rate is not exactly 48.000 but 47.928 or 47766.8 or else so I tried to export the audio as a 48.000 aiff-file. But that doesn't help.
Even in quicktime the video is off-sync.
Can anybody help me with this?

Have you had good luck with the DAC-200 and VHS previously or is this the first time you've tried it? Do you have access to a timebase corrector that you could process the VHS video with prior to the analog to DV converter?
DV audio uses DV video as its sync source. If the timebase of the VHS is bad enough that the DAC-200 cannot make a stable video source from it, it won't be able to lock the audio at 48K.
Things you could try:
Adjust tracking on your VHS player (this may improve the clarity of the sync pulse enough to make it work).
Dub the VHS to mini-DV and capture that instead.
Put a TBC between the VHS and the DAC-200.
Have someone with an analog capture card capture for you and put clips on portable Firewire drive.

Audio rate problem? or tired MAC?

Hi everyone, I do hope that someone can help me..
in this (for me) important moment..!
I have an Final Cut project, which includes different versions (language,
length, with logos etc )of one movie.
Now I am finishing the English subtitled version and I
haven't yet backed up the finished movie in a tape.
But my Mac, which has continued doing editing for 1 year and half,
recently acts strange; the immage and the sound becomes unsyclonized.
Yes, it is not a new problem, but 4 times out of 5 the cassettes
don't come out perfectly, which seems to me too much.
The MAc also show the problem with Final Cut HD: the immage doesn't show
up in a conectted video camera, so I can't make a cassette at all.
The problem 1:
I have stupidly built the project
inside the computer not in external HD, so I can't reinstall
the operation.
(The free space now is 90Gb. Doesn't seem too small..)
The problem2:
Only now I have found that one of the long video clips that
I used for all the versions have a strange audio rate: 48.001 Khz.(Pricisly
it also shows 48000.8Hz in browser.)
When I see this clip in the Viewer it makes PI PI PI sounds,
but since I had finished editings before in Imovie, I didn't notice them.
Moreover, until now other versions from which I made cassettes didn't show
any strange problems even though the audio rate was also slightly different.
My question is:
1
In general, when you find a clip like this (with strange audio rate )
is it necessary to replace it with a new video clip? What is the cause??
Could it cause problems when I will make a DVD with
DVD studio Pro, exporting Quicktime mov. file into it?
2
To refresh my computer.. (it seems an only solution.. isn't it?)
will it be risky if I bring my Mac to a technical support to have it
reinstall, saving all date of Final cut project? Could it damage the project??
Could it be helpful makink a quicktime DV pal file to save the timeline,
so that I can reimport it in Final in the case of damaged project?
If someone has a good solution..I will appreciate it very much.
Thank you!

Hi Al, thank you for the post,
RAM is "1.5GB DDR2 SDRam".
The footage was originally captured into imovie; secondly
it was exported into a cassette. (The project was purely Imovie one
before I started subtitling it with various color and sound correction.)
And then I imported it into a Final. But the process was all complicated;
I had mixed several cassettes to compose one timeline..because
some cassettes from Imovie timeline had dropframes.
I wouldn't be able to refix it anymore..
Now I am trying to export the timeline into Quicktime DV-PAL file,
at least to be able to try making a DVD in DVD studio pro,
and to save the finished movie in someway.
(Isn't Quicktime DV-PAL file re-importable into Finalcut project? Or is ther
any other format that can be helpful for me? )
Grazie,
MInobu

SB Xtreme Audio Notebook optical out problem with Home TheaterSystem-HELP!

JSB Xtreme Audio Notebook optical out problem with Home TheaterSystem-HELP!, I have this sound card connected?(optical OUT) ?to my home?theater system's digital IN ?through the recommended /8in. optical miniplug-to-optical SPDIF cable. Theater system is set correctly to Digital-In mode. I have no sound!
The cable is a Velocity Toslink-to-Optical Mini Plug digital cable. I don't see any settings in the Creative Console Launcher. The notebook is a Dell XPS M730 (Vista 32).
I have a PS3, DirecTV, and the SB Xtreme Audio Notebook cable on a hub switch that connects to the system's?one Optical IN. The PS3 and DirecTV sound perfect!
The sound card works fine with standard PC speakers. I'm at a loss as?to what to try next. I set this whole system up myself, so I'm pretty good at working out the kinks, except this one!
Karen

OK. I just went to Control Panel - Sound - Playback - Digital Output Device (SB Xtreme Audio Notebook) - Properties - Advanced. I experimented with different sample rates and bit depths. Clicked the test button and lo and behold - sound from the HTS! I've tried iTunes, PowerDVD (configured to digital output) and YouTube - no sound! Am I missing something really obvious?
HA! Just backed out to Playback and selected Digital Output Device (SPDIF) and set as Default. Sound is emunating from HTS! Well, that mystery is solved! Who knew.
Thanks anyway! Any comments or advice will still be appreciated.

PE7 " Unsupported Audio Rate in file " error

Hi
Here's hoping someone can help!
I have a little Fuji digital camera that also does short movies. We need to edit them together for my daughter's homeowrk project.
However when I try and read in the .avi film using Media downloader, Premiere elements 7 tells me that the Audio Rate is unsupported and therefore there is an error and they will not import.
By the way, they import into Windows Movie Maker just fine so there does not appear to be a problem with the files themselves.
This is driving me mad as I bought PE7 to do this and it won't work, didn't want to use WMM!
Thanks

For file format conversion, I use DigitalMedia Converter to do batch file conversions. It handles both the Audio and Video and outputs to DV-AVI Type II files with PCM/WAV 48KHz 16-bit Audio. I'll load it up, point it to an output folder, get a cup of coffee and when I get back, all is done. It is shareware, not freeware, but has worked perfectly for years and many thousands of files, of all sorts of CODEC's. Note that it requires that any necessary CODEC's be installed on the system, as it does not ship with any of its own, which is a good thing in my book. Some converters will add their own CODEC's, and a few will overwrite properly installed CODEC's with versions that are not the ultimate. I like the fact that it works well with all players and other utilities, that I have, so I do not need to install alternatives, or remove anything else, that works on my system. I have used DMC so much, that I have a copy of it on every one of my computers.
Also, check your camera to see if you can set the bit-depth to 16-bit, and the rate to at least 22KHz, for the Audio. Many cameras allow you to adjust this, and that might get your files (for next time) into spec. If you cannot change this setting, then conversion will be your only choice.
Good luck,

Unsupported Audio Rate Error

I stopped using PR4 for a couple of months due to being away etc, and came back to use it only to find that none of my existing projects work and any new vid file I try to add I get an 'Add Media Error' stating "Unsupported audio rate in file"
I didn't change anything, but it stopped working. I tried uninstalling and reinstalling and same error. I use XP Pro SP3.
This is a new one on me. Any ideas?

Alan,
I'd be interested in seeing what G-Spot shows for the CODEC on your AVI. The AVI extension indicates a "wrapper" only. It could contain material of all sorts with dozens, if not hundreds, of different CODECs. G-Spot is a tiny, freeware program (www.headbands.com/gspot), that will give a wealth of info on what is inside many AV format files. It works 100% with AVIs and about 95% with MPEGs. When one gets to WMV and MOV, it does fail to gather data with greater frequencey. G-Spot will also tell you the Audio CODEC used and all data on the sampling rate and bit-depth. (See below)
My *guess* is that you need a particular CODEC (maybe one of the DivX, or Xvid), that you once had on your system.
When something once worked, but no longer does, it usually indicates a change in the system. Many folk will upgrade their OS from say XP to Vista, and all of a sudden things do not play, that once did. It usually requires a download and install of some missing CODEC.
I don't know PE that well, but Pro, Soundbooth and Audition have no problem Importing 44.1KHz 16-bit and up-sampling to 48KHz 16-bit material - mono, or stereo. That *shold* not be a problem.
Try G-Spot and let us know what it says about your file(s), especially the CODECs used.
Hunt
PS if you upgraded from XP-SP2 to SP3 in the down-time, something could have become fritzed there. XP updates seem pretty good at not breaking existing settings, but one never knows. SP2 to SP3 didn't change anything for me on three systems, but that doesn't mean that it would have gone perfectly, if I had four systems.
PPS I don't know the answer to this, but Barb, or Steve, probably do. Can Alan start a new Project in PE, using the 1024 x 768 x 15fps with a custom setting? He could then Export to whatever his desired format was, after editing. If he's using a DV preset, PE has to do several things: re-code the AVI to DV-AVI, change the dimensions, the FPS and the Audio sampling to 48KHz. That is a lot of work. In Pro, one CAN set the Project to the Assets - I just don't know in PE. (Thanks)

48 Khz Audio Rate with 12-bit Format

I'm capturing some old DV footage shot in 12bit format. However, when I capture, it is showing as 48KHz audio rate. As I understand it, 12-bit format should equal 32KHz rate.
I've got a Canon HV30
I've tried NTSC Firewire 32KHz in easy setup and also NTSC Firewire Basic 32KHz setup.
But the captured video Item Properties is still showing 48KHz.
Is this a problem?
Thanks,
Billy

Ian,
I think I figured out what happened. If you could verify this, it would be helpful.
As I went back through the video with the audio out of sync, I realized that it hit a spot in the tape where the timecode got out of sorts because I had a block that had no recorded info on it. In other words, I did not do as I should have and pre-recorded the tape to get the consistent timecode. The out of sync problem started happening immediately after that point where the "gap" occurred.
For some reason, iMovie seems to handle this problem better than FCE by essentially breaking the clip off at that point and starting a new clip when the new timecode comes into effect. FCE seems to "choke" on it a bit and then the audio goes out of sync thereafter.
That is my best guess as to what happened from what I'm seeing. Could what I describe cause the out of sync problem?
Thanks,
Billy

Audio Rate

I recently filmed the wedding of my nephew for the purpose of creating a record of the event for them and their overseas relatives.
I used 2 tapes (Fuji 80min) and filmed with my Panasonic DV camera. I've recorded plenty of footage on this camera that I have used to produce several different movies.
I have just captured the footage off both tapes. The first tape which was full (ie 80 minutes) and the second tape that only had 7 minutes both captured with any errors etc.
When I try to put them on the time line, I'm getting a problem I've not experienced before. The second tape works perfectly. The first tape (all clips) when put onto the time line produce the red line across the top meaning rendering is required. When I look at the properties of the problem clips I find that the audio rate is 48000.2Hz . The same check done on the clips from tape 2 reveal audio rate of 48.0kHz.
HELP!

Maybe your User Preferences>General>Audio Playback Quality is set to High. Change it to Low for normal editing. The Red Audio Render line may disappear if this is the case.
Re 48000.2 Hz: The camera must be set to record audio at 16 bit qaulity which matches 48kHz FCE Easy Setup Sequences.
Did you have a 48 kHz Easy Setup assigined before capturing?
Some cameras do not record at precisely 48 kHz, hence the small variance. FCE handles this automatically unless you are using Version 1.

Different Audio rates & audio formats = drop frames?

I´m getting a lot of drop frame errors during playback in the time line.
Now that I want to print my movie to tape the drop frames of course disturb this process, making it impossible.
I noticed that I have material with different audio rates and audio formats. Could this cause it and how do I make a conversion so that all of my audio is the same rate & format.
Audio captured with my camcorder is: 48KHz, 16-bit integer.
CD music in time line is: 44.1KHz, 16-bit integer.
Timeline is: 48KHz, 32-bit floating point
(The things that FCP suggests to do when drop frames occur; turning RT to Safe, buying a faster computer etc. havn´t helped, so the problem must be somewhere else)

You could try exporting your sequence as a self contained QuickTime Movie. This would give you one file with one set of rates and formats. Be sure to set up the export for 48Khz 16 bit. Once that's done, import the file back to your project, place it in a new sequence and try printing that to tape.
If you're just concerned with getting smooth playback in the timeline you could also try doing an audio mixdown. This is a good thing to do before printing to tape as well.

Unsupported audio rate in file during import

I have an XVID video I'm trying to import. Premiere stops and displays unsupported audio rate. I'm trying to use Virtualdub to get around this, but Premiere keeps reporting the same audio rate problem. I tried to copy the video with no audio (made a seperate wave file), but Premiere still reported unsupported audio rate.

I used virtualdub to uncompress both video and audio and that appears to be working.

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
ftp://ftp.hp.com/pub/softpaq/sp59001-59500/sp59291.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow thisand then proceed with the uninstall.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Start the notebook and let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.

PCI Express X-FI Xtreme Audio - Mic and mixer problems

6PCI Express X-FI Xtreme Audio - Mic and mixer problems' Trouble started two days ago when I updated to the latest X-FI drivers. Now I have no mixer and I can't figure out how to get my mic to work. The only thing that has changed is the updating of drivers. I am using senheiser headphones with mic for use on ventrillo. In the old set up I could go into the mixer and tell the software that the Line-In was a mic and it would work perfectly. Now I can't get the mic to work at all since there is no creative mixer. The windows mixer doesn't allow you to do anything worth wild.
I don't have the old software so I can't go back to the old setup. I am using Vista 64. What the heck am I doing wrong? Why won't the software now recognize that I am plugging in a mic!?!?!?
BAH!!!!
PLEASE HELP!

Doesn't Vista have some sort of automatic checkpointing feature that gives you a way to back up to a point before you updated the drivers?

Audio stuttering dropouts-capture problem

Problem: Intermittent audio dropouts when playing back a capture
from within FCP. It can be fine for many minutes, and then sections
where the audio sounds like quick and repeated missing information—
like a CD that is skipping. The video always looks fine, even in
these problematic sections
My equipment: Powerbook G4 17”, 2megsRam, FCP 5.04. OSX 10.4.7,
Cannon XL2 camera.
In order to solve, we just bought from Tekserve: G-Raid 500megb,
hooked up to the internal firewire 800 port, and a new Iogear
Firewire Cardbus adapter—so the camera can be hooked up to this
separate Firewire bus.
Software settings: the video tape (miniDV) was shot in 30p mode. I
have duplicated the FCP stock DV NTSC preset settings, and duplicated
them so that the scanning is set to Progressive, instead of
Interlaced. This is the only change. The camera was set to just
record channels 1&2 (as is the FCP capture presets), so it is not an
issue of the channel 3&4 audio.
The audio plays back fine from the camera itself. It is just the FCP
capture that has the problem. No other devices were hooked up to the
laptop at the time of capture, except for a wireless Microsoft
Mouse. The problem does exist even after we transferred a copy of
the media files to another computer—so it is the file itself.
Any thoughts?

Thanks for your suggestion, but I’m afraid it didn’t help. A render-only Mixdown of audio still had the problem. In fact, you hear the problem consistently at he same place on the master captured file, playing in the viewer. It seems to only happen on long master clips. (I typically capture in 15 minute blocks, then subclip from here). To solve the problem, I have been creating another subclip of the problem area, making it offline, then recapturing just this small clip where the problem lies. I’m missing my work deadlines because of this.
Any other ideas? Could it be my camera—which is still fairly new—needs a professional cleaning? Could it just be a problem with Canon and Firewire? Would a Powerbook Pro help?

Realtek high definition audio has a driver problem in windows7(32bit)

Hi...
I am installed realtek hd audio drivers in windows7 32bit for no sound(red x mark at sound icon taskbar). Its installed successfully, but it showing error like.. 'realtek high definition audio has a driver
problem'.
Please help me! how to fix the problem(Intel P4(Model-D101GGC)).
Thank u

The support page for Intel D101GGC Desktop Board is here:
http://www.intel.com/p/en_US/support/highlights/dsktpboards/d101ggc
The audio driver listed is the Realtek ALC Audio Driver. You can download the Vista/Windows7 driver here:
https://downloadcenter.intel.com/Detail_Desc.aspx?ProductID=2229&DwnldID=19472&lang=eng&iid=dc_rss
Is this the driver you are having problems with? If not, suggest you uninstall current non-functioning driver package and install this one instead.

Audio rates apparently don't match FCE and recording Is there a cure?

I am using a Panasonic DVX100A to transfer a miniDV tape shot on an inexpensive consumer DV Camera into FCE-HD, but at the conclusion of the capture I get an error message that I need to set the audio rate to match that of the camera. I'm new to editing so I'm not sure what that means or how I find out what the audio rate of the camera is so I can set FCE-HD to that rate---or does it mean the audio rate at which the tape was originally recorded on the consumer DV Camera? If so, is there a way to know that audio rate without having access to that camera?
thanks.

I'm going to venture a guess that the video was recorded as 12-bit audio (usually the default setting in miniDV camcorders) ... and you're probably using the DV-NTSC easy setup in FCE. The DV-NTSC easy setup expects 16-bit audio. Try changing your easy setup to DV NTSC 32KHz and then recapture the material into a new sequence.
Also check your DVX settings - is it set for 12-bit or 16-bit audio?
And contact whoever shot the video and ask them to check the settings in their camcorder & let you know what audio setting it was or is set for. (12-bit = 32KHz, 16-bit = 48KHz). If it's 12-bit, they should change it to 16-bit for future shoots.

Audio rate doesn't match

So I figured out I could capture video with my old Hi8 camera through a firewire. I use easy set-up with DV-NTSC. The camera gets controled by the capture window, looks for time code, everything is smooth. However, it tells me that my audio might be out of synch because the audio rate doesn't match. What is the standard audio for a Hi8 tape?

It's probably simplest to check your FCE Easy Setup, which will be either 48kHz (not necessarily specified) or 32kHz. Switch to whichever one is not your current selection and recapture.
