Autosync - Sync Detection Problem with Video/Audio from different sources

Hi,
i've got the following problem:
I'm editing a feature film, where video comes from tape and audio from harddisc-recorder. The clips are combined/linked manually via in-point (slate).
If I cut this video/audio combined clip in the timeline, and move only the audio 3 frames to the right, sync detection informs me correct about the out of sync problem (3 frames). BUT: If I split the audio file in two pieces, the left clip still has the "out of sync" info in the timeline and remains "linked" to the video, but the right clip doesn't show his relation to the video anymore !!!
Is this a bug ?
Because, if I use video and audio from one "media-source", ex dv, the sync detection in the timeline is working correct with the above example ?
I'm lookin' for a similar way to sync clips like autosync with media-composer and thought combine audio and video clip to a new combined clip should do this....
Thanks for help !

I have my waveforms back! Thank you SO MUCH! I looked everywhere and just couldn't find a setting for this.
As for the sync, I guess that's OK - it's no worse than what I had before (and with the waveforms back, less of an issue to do manually). Would be nice if they'd add the ability to offset the audio track in the Modify Clip screen at some point (and it would open up the multi-cam sync feature to more users), but I can cope without for now.
Thanks again for your help.

Problem seeing video/audio from thumbnails

Hello,
I have an old iMovie '08 (7.1.4) with clips showing in the thumbnail section, but am unable to view/hear those clips in the preview section. There is a small yellow triangle with an exclamation mark in it in the lower left of the thumbnail. Can anyone tell me what that means, and what I need to to do actually be able to see/use the clips? Thank you for any help.
(oh, and I don't dare update the iMovie software again for fear of a) losing what video I have and b) being thoroughly confused for another three years!)

Hi
There is a small yellow triangle with an exclamation mark in it in the lower left of the thumbnail.
This means that iMovie can not locate the original raw material - most often due to that
folders named
• iMovie Projects - or -
• iMovie Events
been moved.
One must not move or alter anything in them !
Moving movie material - HAS TO BE DONE - Within iMovie application in Events window
(iM'08 only events can be moved) (in iM'09 or 11 projects too can be moved out to external
hard disks)
Try to move everything back to where it was and then do the move in the right way.
External Hard Disks !
• HAS to be - Mac OS Extended formatted (nothing else works for VIDEO)
• Should be a FireWire one - as USB/USB2 performs badly and slow

Recording just audio from a video DVD

I thought I was ordering a CD with the music of a Broadway show. It turns out to have been a DVD of the entire production.
How do I get just the audio from the DVD into iTunes? And while I'm at it, once I get the audio, I'll need to strip the dialogue, and I haven't got any idea how to do that, either!
Hope someone can help!
Jimper

You can use Audio Hijack to record the audio from the Apple DVD player, which can be sent directly to iTunes as an ACC or AIFF file.
http://www.rogueamoeba.com/audiohijack/
Stripping the "dialog" (assuming dialog is spoken commentary during the performance??) will be much more difficult. There are techniques to use a an audio editing program such as Audacity
http://audacity.sourceforge.net/
to invert a one side of a stereo track to remove vocals for Karaoke, but the sound quality will be greatly diminished, the bass and even the vocals may be removed.
So if there is "dialog" on all of the songs it may be cheaper to buy the CD.
Hope this helps.

Recording live audio from a Bus

Hey,
So what I'd like to do is record audio from a bus directly into an audio channel
I have a test oscillator in the input slot of an instrument channel
As you can see, the output is routed into bus 1
In order to process any audio that I have coming into bus 1, from any number of channels, I have bus one routed into an Aux channel, from which I can run any effects. Aux 1 (w/ Bus 1 in the input slot) is routed to Bus 2 (Bus 1 w/ effects from Aux 1)
As I said earlier, I'd like to record the audio from a bus, in this case Bus 2, into an audio channel so that I've got a continuous audio file. I figured the best way to do so was to create a record-enabled audio channel, with Bus 2 as the input, which I've done here
As the screenshot shows, the audio from Bus 2 is making it into the channel.
When I hit the record button, with "Audio 3", as the selected track no audio is recorded.
In other words, I can hear the audio, and I can run it through any processes, but I'm unable to record in a way that allows me to capture the live processing of the sound.
I tried googling the matter and some suggested bouncing the track the project, which should leave me with an audio file, in the bin, of the audio with any automated effects processing. Logic's stopped responding, with the mini "bouncing" window on the screen both times I've tried to do this- I'm not sure if this is a seperate problem, which I'll have to deal with at another time or if it's related to what I'm triyng to do.
In any event, has anyone come across a way to route the audio that would allow me to record this audio live, without resorting to recording only the effects parameters and bouncing?

Thanks CCT,
Checked the prefs and switched them to built in and it cleared it right up, but it did bring up another issue, because I don't remember ever switching it into the "none" position.
I'm working with a USB audio interface that I remove when not in use; possible that logic automatically reverts to "none" rather than "built-in" when I remove it, and can I make it so reverts directly to "built-in" when the interface is removed?

I stream video/audio from my iPhone to AppleTV and it works fine. I want to use headphones on the iPhone so I can stream the video and listen on the headphones, but Airplay will not allow me to select both AppleTV and headphones, I can only select one.

I stream video/audio from my iPhone to AppleTV (like YouTube) and it works fine. I want to use headphones on the iPhone so I can stream the video to AppleTV and listen on the headphones, but Airplay will not allow me to select both AppleTV and headphones, I can only select one. How can I watch AppleTV and listen on the headphones?
Thank you.

have the same problem. Im using iPad 3 and Apple TV. id like to use the ipad as wireless earphones while i watch the video on the tv. is that even possible?

Brutal error message OSStatus error 2003332927 Can not record video/audio

I have QT pro 7.6 and since a couple of weeks ago, I have been unable to record video or audio.
Any Ideas what this error code means and how I can fix it?
thanks everyone!

Hi there.
After further testing I have found that the reason I was receiving the Brutal Error, was because of my DigiDesign Core Audio Driver.
If I am using the MBox, and Digi Core Audio, (i.e Mbox I/O is active) Quicktime Pro will not record video/Audio.
If however I switch back to the Mac audio out (disconnect the MBox), Quicktime Pro works fine.
I havent had time to "fix" the problem in the Digi Core Audio, but this was the source of my Brutal Error Code.
Hope this helps.

Does Premier Elements allow me to record video streaming from the internet?

Does Premier Elements allow me to record video streaming from the internet? If so which version and how?

kc42k
Although Premiere Elements is not going to record streaming video from the Internet but there are other programs that can, you should consider the terms of service for the web site that is the source for the streaming video.
Online, there are very comprehensive articles on numerous programs that will do the recording.
But, even those articles point out that many of the Internet web sites that you target for their videos have terms of service that would legally prohibit the recording of streaming video from the named web sites, one example, YouTube, if no download button and depending on the terms of service.
Please consider. Any questions about the above, I can point you to the appropriate documentation on the matter.
Thank you.

Recording video/audio files using Flash Meida Server through rmtp, and allow users to access the recorded files through http.

As titled, what is the way to record video/audio files using Flash Meida Server through rmtp, and allow users to access the recorded files through http?
What I am trying to do, is to record a user's microphone's input and save it to the server. Afterwards, I would like other users to be able to access the recorded files and mainuplating the audio data, by computeSpectrum(), to do some visualization of the audio. As I know computeSpectrum() cannot work on streaming files, so I think I need to access the recorded files using http instead of rmtp. Is that true?
How can I redirect the http request to the files I was recorded into my applications/appName folder? Or I need to somehow moved the recorded files to the /webroot folder?
Thanks!

I probably have asked a stupid question.
My recorded streams are still saved in the applications/appName/streams folder.
And I redirect the www.mydomain.com/streams to point to the applications/appName/streams folder.
And the rmtp recorded streams are abled to connect through http now.

Can you record the audio from a Video embedded in a pdf?

I can't seem to find anything on this, so I will ask. A client sent us a company produced interactive pdf and wants us to use the audio from a video clip that is in the pdf. We asked for the audio clip but they don't know who to get it from and just keep saying it is in the pdf. While others try to explain that a pdf and an mp3 are not the same thing. I get to look into a fall back position of trying to extract the audio (or video). There is no copyright issue here. Client peon just can't/won't get the proper file.
Maybe some one can help or point me to info that says it is not possible.
Thanks.

WireTap Studio did the trick. I downloaded a free Trial version and bob's yer uncle.
Thanks Michael

Can you record system audio from a video??

I am trying to simply record a video but there is no options for recording system audio, therefore it will not recrod the sound. Is there anyway to do this?

Hello,
Welcome to Adobe Forums.
You have option of Audio Recording in Adobe Captivate while using Software Simulation or Video Demo (Captivate 6.0)
You can move the Microphone (For Audio Recording) closer to Computer's speaker.

Saving video stream from webcam periodically!!!

Hi there, I want to catch every 1 minute video stream from the webcam, or video file, and save it into separate files. Of course I woudl like to have possibility to save many streams simultaneously. Any idea?
Best regards

Hi,
I want to do the same thing ... I was able to stream audio through the socket but could not stream video.
I posted my question at http://forum.java.sun.com/thread.jspa?threadID=674676&tstart=15
and presented a sketch of my implementation design. But until now no one has answered my question.
This is how you should hook up the components on the transmitter side
Webcam --> Processor --> Custom DataSink --> PushBufferStream --> PushBufferHandler --> Socket --> Network.
You can implement the transferData() method of the PushBufferHandler to write to a socket.
And on the Receiver side the components should be hooked up like this
Network --> Socket --> PullBufferStream --> custom DataSource --> Player
Now as I mentioned in
http://forum.java.sun.com/thread.jspa?threadID=674676&tstart=15
the audio works fine but the video does not. The video does not render on the receiver side.
Note: I tried TCP sockets with audio and it is terrible (not practical at all) so I reverted to UDP datagrams and the result was better than I expected. I didn't take care of the ordering of received packet at the receiver but it still worked fine.
I am still looking waiting for some help in why video is not rendering and how can I sovle this problem.
I am workning on a project and time is running out.
Any help?

Problems Recording Video with Photo Booth

Macbook Details:
OS X Yosemite
Version 10.10.2
MacBook Pro (15-inch, Late 2011)
Processor 2.2 GHz Intel Core i7
Memory 4 GB 1333 MHz DDR3
Photo Booth: Version 7.0 (724)
Some background: It all started going downhill for my laptop when I got a "Service Battery" warning back in December. Thought it could possibly be a glitch from the new OS. In any case, they told me to wait it out till the Full Charge Capacity reaches the 2000s. It's currently at around 4225 and slowly steadily decreasing. I can't keep many applications open at one given time.
The problem: Built-in camera is working fine with Skype, FaceTime, etc. Photo Booth pictures are fine as well. Simply unable to record any video with PB. It will sometimes record, but during recording, the image freezes. Upon playback, the image is frozen for the entire video, and audio lags or skips around. Today it froze and actually sat frozen all day while I continued to use other applications.
Is there anything I can do??

You can't record video with PhotoBooth, you can record video with iMovie, or you can record with Quicktime if you have the Pro version. I would suggest using iMovie, create an MPEG-4 project, record your footage, drag your recorded clips into the timeline, then choose the Share menu and choose Email.
Baby footage will be on its way to the grandparents in no time!

Problem when exporting audio from Premiere Pro v4.2.1 into wave 5.1 format

Hello to Adobe experts!
After installing of last updates for Adobe Premiere Pro (v4.2.1) and for Media Encoder (v4.2.0.006) the was a problem:
Now I cannot to export audio from adobe sequence into uncompressed wave format with 5.1 channels settings. Source m2ts video files in sequence are with 5.1 audio.
What I doing:
1) in Premiere I execute "File\Export\Media"
2) Export settings are:
- format: Windows Waveform
- audio codec: Ucompressed
- basic audio settings: 44100Hz, Channels: 5.1, Sample Type 16bit
3) After OK button it opens Adobe Media Encoder.
4) After pressing Start Queue in Adobe Media Encoder there is a message "Error compiling movie. Unknown error"
In earlier versions it worked fine.
Can you help me with this problem?
Alexander

Here are the options, from a sequence with 5.1 master track:
and with Surcode:
Notice that first one does only give stereo as an option. Nothing more. With Surcode it gives you 5.1 sound.

Is it possible to stream live video & audio from device cameras & mics to a server?

I would like to know if I can use flash builder to stream live video and audio from Android & IOS device cameras and mics to a media streaming server such as Flash Media Server or Wowza? I know the Android & IOS APIs allow for this but can it be done using Flex/Actionscript? The key here is "live" so you wouldn't want to have to wait for video and audio files to complete on the disk before sending it out. Ideally you would send it out via RTMP or HTTP streaming to stream out but any stream would do since once it gets to the server you can encode it.

Hi
Yes, It's can do but There is a problem on IOS 8 when Switch Camera, Microphone is muted and Sound return when I press home button from my iphone out and press app again for few second
You can use as same as flash desktop video streaming for coding in mobile.
Good luck
