Audio and Video Capture, Live: Problems

I am trying to do a live capture of a demonstration using a video camera (DV) and a lavalier mic into a Griffin iMic. For speed's sake, I am trying to eliminate the TO TAPE step. I only want to capture. I can just edit the captured clips that way.
Audio is being picked up through the DV cam, and I cannot seem to force FCP to grab audio from the iMic source... I don't know where to change the audio source. Can someone help me do that? The camera is behind me, and so the sound it picks up is unacceptable.

That's a good idea.
This cam ($200 DV refurb Sony) does not have a mic in. I do have another cam with Mic in, but pluging the lav. mic (mono) into it generates a BUZZ on the other channel. So I have tried that, but it requires a lot of post editing.
My current solution is to record Audio using Sound Studio. I start the audio recording, switch to FCP, start the capture, then smack a couple of sticks together on camera (for my clapper board) and will sync the audio later. Loosk workable. I have two different drives recording data, and the Mac seems to be keeping up (gulp).
Would LOVE to be able to get FCP to only capture video from the DV cam, and audio from the usb iMic. That would be my fastest record-to-final option.
Thanks for the ideas.

How to stream audio and video captured from mic and webcam in sync.

I am working on a video chat project. I need to capture audio and video from mic and webcam and create rtp stream for them. How can I proceed for this. Any source code help will be highly appreciated. Otherwise just guide me how to do this and point to any good resource which is directly related to my need.

Synched Audio and Video Capture in JMF?

I am in the planning stages of developing a speaker's corner for our university television station. Essentially, a button pressed by the user and a JSamp will send serial data to the computer(PC) that will execute the capture program. Before I proceed further, will I be able to capture both audio and video so that they will be in synch so that I can later bring both into a commercial video editing platform? Also, does the JMF support capture by firwire or USB only? Most of the forums seem to indicate that it is USB. Thanks, and any other advice would be appreciated.

Synchronize audio and video over RTP

Hi all,
I am new in jmf. Please any one tell me, how to synchronize audio and video streams, when we capture thru audio and video capture devices and send it over network thru rtp protocol and receive at client side. How to syncnronize at client side? Please send me reply if any one have solution in jmf.
Thanks in advance.

Does anyone know about how this is done? I'm doing a videoconference thing with jmf, QoS is a required componenet! So if anyone knows about how this is done, plz share with discussion! All I know so far is that I can buffer the incoming streams to some extend then call syncStart() to start the video with the starting time of the video!

Audio and video out of sync on capture

I have been using the Canon HV20 and MacBook Pro for about a year now with no problems and for the first time today on capture the audio and video are out of sync. I have been using an external LaCie for capture and stoage but even using the internal HD, the same problem is occurring. I checked my preferences in FCE and used the disc utility to make sure my HD had no permission problems. I am not dropping any frames on capture. What do I do next to correct?

Hi - Thanks for you response.
It's a Canon XH A1 which is an HDV camera. As far as output is concerned when I play the camera it says HDV 24 and the sound is 16KB.

Audio and video out of sync after capture from Canon

Help for a newbie please? I have a Canon XHA1S and have a problem after capturing HD video. After capturing a 40 minute clip, the audio and video are out of sync. Seems like there is about a 3 second difference. The entire clip is like that in the source window; I made a couple of quick edits and have the same problem in the program window. Tried exiting and re-opening PP, but that didn't help. I'm running PP in CS6 on an iMac 3.4 GHz i7 with 8G of ram. Thanks!

I have NOT used it, but many say to try this for HDV capture http://strony.aster.pl/paviko/hdvsplit.htm

Capture audio and video files to seperate files

Forum,
Having suffered problems with OS 10.5 and Quicktime 7.4.1 I have done a clean install with 10. 4 .11.
When I select capture the following notice appears
"Audio only capture selected,video preview disabled"
In system settings "capture audio and video to seperate files " is NOT checked.
But that may not mean the same as the statement in in the capture window.
I have searched HELP and a book called" Optimizing your Final Cut Pro System" but can not find an answer.
Advice would be appreciated.
Thank you
Michael Craven

Hi,
Check this:
in Log & Capture window select Clip Settings tab and make sure video box is checked.
Cheers,
G.

Capture and streaming audio and video

JavaFX supports capture and record audio and video and need some streaming server as woonza, red5, flash media server to play the streaming?

JavaFX does not support flash streaming.
JavaFX does support http live streaming: http://en.wikipedia.org/wiki/HTTP_Live_Streaming
JavaFX does not support audio/video capture (there are other java/native libraries that do that).
See:
Video camera capture/streaming: example implementation "Thread: Video camera capture/streaming: example implementation"
http://javafx-jira.kenai.com/browse/RT-3458 "Camera and Microphone" (go vote for this jira to get some capture technology built into JavaFX).

1080i60 video captured file has 3-13 sec. time diffrence, audio and video

capture from camera (mode HD 1080i60) to imac G5 1.8Ghz ( allocated disk space is 500G) for 4 hours audio and video has no longer syncronized, time differences are about 3 to maximum 13 second. this can be checked by quicktime, after captured.
disk has no error
this case is also proven apple japan technical center.
our case only FCP runs, no other application started.
FCP 5.1.4 os 10.4.11
if parson in charge in apple usa, please contact to apple japan for more details.
FCP might have serious problem on capture routine

Thank you for your kind reply, appreciated.
i operate two imac capture system same day for operation. specification for both system are identical.
from your advice, i checked .mov files by QT, which captured that day.
condition:
both system's FCP capture operation are closed 4 times by escape key for creating files, after created file. i again start for capturing the data. and no other application are initiated, except FCP
system A has time differences audio and video, but not always there are time it is good.

Premiere Pro CS6 importing/ audio and video problems

I recently recorded gameplay from my xbox, when i open this recording using windows media player it states that the video is 3 hours 30 minutes long, which is correct, when i then import this into premiere pro, premiere pro changes it to be 5 hours and 44 minutes long, when i then play this back it plays in slow motion and audio and video start to desync, i thought it may just be the source editor playing up so i made a clip and put it into the timeline and it still had the same outcome. The speed/duration are still on 100% so im not sure what to do, anyone have any idea as to what this is, or why it is happening?

What are the attributes of your PVR video...
specifically, is it variable frame rate?

If it is VFR, Premiere no-likey.

Capture Audio and Video to different disks or not?

I thought that capturing audio and video to separate disks was more efficient, now I see in the FCS 2 documentation it says that this is not recommended for any of the DV formats. But it does not say why, or what the consequences of doing this are...
Does anyone out there know?
Thanks,
Pete d.

Now, Is there any value in putting the render files on a drive that is separate from the Capture disks?
Pete D.
Absolutely. Listen to your drives while doing an intense render. The Capture drive is grabbing all of the video clips in the stack, the system drive is grabbing software. If you render to the Capture drive, that same drive has to write, too. Reduce the load by using a Render drive.
I have four drives: System, Capture, Render, Output. The last is used for all exports, encodes, and transcodes.

Audio and Video Out of Sync -AV sync problem

Edited a bunch of clips together from Canon T1i 720p, iPhone 3GS, Canon SX110, and Sony DSC-W70. About an hour long. Everything looks great when played within iMovie '11, but when exported, the audio and video get out of sync. It gets progressively worse the farther along you are in the sequence. AV is as much as 6 seconds off by the end!! Audio is ahead of the video. I've tried exporting in several different ways including: Export to iDVD, Export to Media Browser 720p, with the same results.
Anyone else having this problem? I know I've done this with success in the past with iMovie '09.

Im having the same issue I have a project that is 9 minutes long tried all before even looking at the forum but It will not sync. Some one even told me to repair the permissions so nothing worked. I went to the Mac store no body knew what I was talking about so they asked me to call Apple so I did and was hung up on 3 times not only that but I was advised since I just bought the product I did have 3 months of tech support.
I mean I'm having an issue and they tell me I have 90 days of free service? This has got to be a joke. I than asked well can I just take it back and instal my 09 back? I was advised nope you wont be able to do so and you cant get your money back.
After this whole mishap I did learned that the less snips and clips and editing is on the project the sync and video will be ok but if you have lots clips such as most of us than we will continue on having this issue.
We need a fix ASAP

How to fix problems between audio and video sync?

Hello, I have this old camera DSR 200P and I'm trying to import to my final cut pro x. The importation success well but at the end the syncro between audio and video doesn't work. How can I fix it?
It's possible my mac doesn't accept this kind of camera or should I change any options of final cut?
Thank you

I use to edit footage for a client that was recorded on a DSR-250 (successor of the DSR-200) and every time, every single time, the audio sampling rate would not match my Sequence settings of 48khz, 16bit. The sampling rate of the captured video was always off by a slight amount. It might be 47999.9 one time and 48000.1 the next time ... but it was never at 48000 as it should have been. I chalked it up to Sony using cheap synthesized crystals (frequency generator) to control the rate.
Anyway, the fix was to export the captured clip using QuickTime Pro with the export's audio settings to 48khz, 16 bit.

Audio and video not in sync. went back to previously finished projects and they too are not in sync. What could be the problem?

Audio and video not in sync. Went back to previously edited projects and they too are now not in sync. What could be the problem?

Um ... some useful data?
OS/CPU/RAM/GPU/vRAM ... version of PrPro ... and other programs or plugi-ins/3rd-party apps involved ... footage type/codec/wrapper ... such things would be very useful.

Capturing audio and video .....

Hello everybody, I'm new to the world of Adobe Premiere Elements, a source present. I have a pavilon pc hp m9040n, Windows Vista Premium 32-bit, Adobe Premiere Elements 3.0. I want to capture audio and video on a DVD, the pilot is set to DV / HDV and the HDV format in the acquisition and says that the peripheral acquicision is not online. The same happens when I connect a video camera Hi8 Sony. Can help to solve this?, Thank you very much.

It sounds like you are having problmes capturing from two separate cameras. What are the manufacturers and the exact model numbers please? Also, how are these cameras attached to the computer, i.e. FireWire cable into the corresponding FireWire port on the computer?
It sounds as though you are attempting to do the Capture from within PE3. Is this correct? If so, what is the order that you connect the cameras, turn them on, their settings and the order that you launch PE3, and also the Capture module of PE3? Might be something there.
Good luck,
Hunt
