Can QT 7 pro isolate audio from combined audio/video tracks?

I just upgraded to Pro to try to convert small video clips (.mov files) taken on an HP digital camera into an iMovie-compatible format- they will play fine in QT (both audio and video), but there is no separate audio track. No matter what format I save the clips in, they lose the audio portion. Can QT or iMovie solve this?

It sounds (no pun intended) like the file format from your camera is MPEG-1 (muxed). QT can play but not export or convert the audio. Same with iMovie.
Use MPEG Streamclip (free) to convert your .mpg files to QT formats.

Can a Macbook Pro Dualcore 2,4 ghz handle 8 track simultaneous recording in Garageband?

Can a Macbook Pro Dualcore 2,4 ghz handle 8 track simultaneous recording in Garageband?
I am looking to buy a used Macbook Pro Medio 2010, with a 2,4 Intel Core Duo, 6 GB Ram and a 120 Gb SSD harddrive.
I am mostly going to be recording drums, with 8 individual channels + midi (More likely only 6 channels at a time though)
Is this powerfull enough to record 8 tracks at the same time without any significant hicups?

How can I display & split the audio & video from the same digitized clip?

I digitized a scene into iMovie that I edited on a professional system which I don't have access to anymore. The whole scene is 1 clip. Now I see a few tweaks that I want to make, so I was hoping to do them in iMovie.
I want to "pull up" the audio in one section - meaning I want to take cut about 20 frames of audio from the end of a shot, and then move all the other audio up to fill the hole. To compensate for the missing 20 frames, I'll cut video off the head of the next shot. Some call this prelapping. Some call it an L-cut. Some call it asymmetrical trimming. Either way, I can't figure out how to do it in iMovie.
My clip appears in the timeline as one track - a single track that contains the video and 2 audio tracks. How can I display the audio that's tied to the video on its own track? Then I think I could split audio & video wherever I wanted and trim things up - but I can't figure out how to do it.
Am I asking too much of this software?
BTW, I never see the option to "Split audio clip at playhead". I'm not displaying clip volume or waveforms. Choosing to display waveforms doesn't show me anything. Maybe iMovie thinks I'd only want to see waveforms of audio that isn't tied to my video-and-audio clips?
Thanks in advance for any help...

Jordon,
"Am I asking too much of this software?"
No, you're not.
You first want to select your clip(s) and choose Advanced>Extract Audio.
This will copy the audio from the video clip and place it on one of the two separate audio tracks while lowering the audio level to zero in the original video track.
You can now edit and move the audio independently of the video.
With the audio clip selected, you'll find you now have access to Edit>Split Selected Audio Clip at Playhead.

In which steps of Logic E. can I make a stereo audio recording track with a right and left microphone?

I want to make a stereo recording with a microphone for left and one for right. Can someone tell me the Logic steps to record 2 tracks (mono left and
mono right?) at once, to make a stereo track from both tracks? I use Logic Express 7.

I think it is easy if you have an audio interface that has two mic imputs. You direct each of them to two different mono audio tracks. Then, at the time if playing it, you just pan one channel to the left and the other to the right.
I think this is what you are asking for,
hope it helps

Can i create a multi audio video CD in Encore 5 (CS5.5)?

Hi All,
I was wondering, is it possible to create a multi audio video cd in Encore 5 (CS 5.5)?
Basically i have 5 music tracks that i wish to be able to be played as normal in a CD player, but i would like to add a video to that that can be played on a PC.
I have a few commercial CD's which have this (ie when they are inserted in a PC they open additional pc content) but i have a project i need to finish which would require this.
Is it possible? And how do i go about doing it?
Thanks in Advance :-)

You cannot do this in Encore, AFAIK - but I will have a look in case I am mistaken.
VideoCD uses MPEG encvoding but this is roughly where the similarity ends - VideoCD uses 44.1KHz audio, not 48KHz.
Commercial CD that have additional PC content are again different animals - the way these discs (which are called "CD-Extra" or "CD+") are normally created is in a multi-session CD creation tool. You create the audio content first, then when you write the disc you do not close or finalize the session but leave it open - then you go into CD-ROM mode and add the additional content, this time closing the session.
Such discs can be created quite easily in GEAR Pro Mastering Edition, or WaveLab. What OS are you running please?
You would need to prepare the content outside of the final authoring tool, and commercial CD can (and often do) use Director created content or Flash created content - the down side to Flash is that it will not work on a Mac. You can also create the videos in Quicktime Pro - simply load into it your regular full scale version, and then export for web - this will create 3 separate versions at varying quality (Smart Phone, iPhone & iPad are the references although all will work on your CD-Extra disc.
Please post back if you need more assistance

I have an Iphone 4. I have a video I took with the built in camera. Is there a way I can edit it to isolate a part of the video that I can print a single frame?

I am looking fo someone who can tell me how to edit a video taken with my Iphone 4 so i can copy/print a single frame from that video rather than the entire video. Thanks in advance

What you can do is play back the video in the Photos app, then pause it. Tap the screen to make the controls go away. Then you can take a screenshot: Quickly press then release the home and power buttons at the same time.

Split audio video tracks on iMovie on iPad 3

This has probably been asked before but I'm having trouble navigating through this new support interface to find the answers.
I have a new iPad 3 with Retina display. When I bought it I downloaded the latest version of iMovie for this iPad.
When I drop a video clip (with audio) into the timeline the video and audio are synced. (linked)
So......
How can I easily unlink (split) the video and audio so that I can shift the audio and have that audio play over a different video clip?
How can I split the video and audio so that I can carry over the audio into the next clip in an L cut?
How can I drop in only the camera audio without any video?
How can I drop in the audio and have it play under a still photo?
These all seem like basic operations needed to have a polished little video.
I KNOW iMovie is not Final Cut but I don't want a movie made by
iMovie on this iPad to be just straight video clips married to the original audio.
There must be a way to do this but it doesn't seem obvious so I hope you can tell me how.
Thanks
Steve

You cannot do any of this in iMovie iOS.
It is just a basic editor that does not have any advanced audio tools.

That is all you can do on the iPad sorry.
It's not built for compex editing.
You could try Avid on iPad.

Does Flash Access support encrypting the specific audio/video track in a multirate video file?

Hi,
It seams that Flash Access supports encrypting the multirated mp4 file. By setting encrypt.contents.video=true, encrypt.contents.audio=true, the encryption process will encrypt all the video tracks and audio tracks inside this mp4 file.
I am wondering:
Does Flash Access support encrypting the specific audio track or video track by giving the trackID for a specific bitrate inside this multirated mp4 file?
Thanks in advance,
Xia Hui

I am not aware of existing or new feature which allows to encrypt particular track. You can encrypt all audio, all video or both.

Exporting MPEG 2 files with audio & video tracks COMBINED?

I want to post a film on Google Video. I'm told they like MPEG2 files, but with the audio and video combined.
How can I create an MPEG2 with the video and audio combined?
I've also been told I can change the .m2v extension to .mpg after I've encoded, without causing problems. Their 'uploader application' doesn't like the .m2v extension.
Thanks,
Ben

Compressor's standard mpeg2 export presets are set up to create separate audio and video files. Changing a m2v extension to mpg does nothing. You still have a file with only video.
However, deeper in Compressor is the means to create muxed (mixed audio and video) files. Do a search here, it has been discussed a few times.
Still, why not send them an mpeg4 file?

Can I add a separate audio commentary track?

I would love to add a separate audio track with a running commentary to my movie. Something that would be an option to play, like some DVD's have with directors comments, etc. Is this possible with iMovie or iDVD?

You can add an audio track with your comments: select the Audio tab and you have there a Record button. You need to have a microphone plugged.
But the final movie will have only one audio track. Also iDVD can not handle two (or more) audio tracks.
You need DVD Studio Pro for that.

Can't get good quality audio/video.

I'm creating a video chat application, and no matter what combination of Camera/Microphone/NetStream properties and functions I use, I cannot get high quality video/audio. I get occasional audio latency, pixelated video, occasional frozen video and the degree of each depends on the combination of properties/functions I set/call.
Others such as TokBox, TinyChat, Chat Roulette, etc. have achieved great video/audio quality with FMS, what is the secret? At least point me in the right direction, because right now I'm not impressed with FMS ability to provide a good video/audio experience.
BTW, I'm using a P2P mesh using a group specifier, not NetStream.DIRECT_CONNECTIONS.
Thanks in advance!

You mention that if Flash Player is used for encoding you cannot achieve very high qaulity as of now, just wondering how else the encoding would happen, as users of this video chat app would be broadcasting via their web cams. In that case does FP handle the encoding, and what else are my options other than FP?
I think we are using FMS in its default configuration after installation (we use the Amazon Web Services FMS).
How can I "disable aggregate messages or totally disable the queues on the FMS that reduce latency, especially for live video chat applications". I'm very interested in hearing more about that.
Typically there will be up to 8-12 people in the group video chat room, with video pod size of about 147x110 px.
We are using Speex for audio currently.
Hoping more info might move us forward.
Thanks very much.

Can't multitrack with M-audio Fast Track and a Mac Mini

I can't consistently record the two Fast Track channels, vocal and an acoustic/electric, simultaneously. I'm always able to record the channels independently just fine and they both come through if I create a stereo track. Every so often, after a random process of GB re-starts, track record button re-selections, and cable re-insertion, I'm able to get both to record at the same time but it's not a repeatable process. I've already done a permission repair. Any help or recommendations is greatly appreciated.

Hi Jay,
Welcome to Apple Discussions!
One of 2 things come to mind. I couldn't find any decent information but
1. The Fast Track USB might only be able to record either guitar/line in or XLR one at a time. Not simultainiously. I don't know, can't really say as I don't have this box.
2. And this would be my guess. You may need to download the latest driver from M-Audio.
It's been my experience (I had a MobilePre USB at one time) that an updated driver from M-Audio may not solve your problem. They aren't the best at supplying functioning drivers.

Can mac book pro quadcore playout uncompressed full raster video?

Hello, I' ve a MBP quad core, 2,1 mhz, 500 GB HD, 7200 rpm, 8 GB RAM.
I'd like buying a AJA IO HD for video signals' connections and up-down conversions. IOHD can connect MBP by FW800. AJA claims chance to import-export (from/to laptop) uncompressed full raster 10 bit HD video by FW800, but it seems difficult for me to believe it, for FW800 low data rate (800 MB/s), respect HD uncompressed data rate (1,5 GB/s).
Thanks for your answers
Amedeo

dont know what to say ... it works fine on mine
try trashing prefs, repairing permissions, re-booting, and all that jazz
try creating a new user account and see if it works there

How can I make a mixed audio/video playlist?

I would like to make a playlist of music videos. iTunes seems to consider "music videos" as a separate type than video files. The problem is that some of my music videos are detected by iTunes as formal "music videos" while others are detected as "movies". While I can add them all to the same playlist, I can only play the playlist as one of the two types, and it will ignore the files of the other type. For example, if I access the playlist through my music playlists on my iPhone, it will only play the music videos that iTunes thinks are actual "music videos" and will not play the ones that iTunes thinks are "movies". Same problem in the opposite direction if I play the playlist through the movie/video interface.
How can I get them all to play together? They are ALL videos, and all in the same format (.mp4), so I'm not sure why iTunes is so confused.

Well, good news and bad news. I found out how to tell iTunes that all my music videos are, in fact, actual "music videos" and categorize them as such. In the "Get Info" screen for a track, there is a dropdown selector where you can pick the "meta" type, such as "Music Video", "Home Video", "Movie", "TV Show", etc. This allows iTunes and iOS to think they are all music videos and play them in the same list.
Unfortunately, this is not compatable with my third party device, which is now refusing to play my music videos in a playlist and will only play them one at a time (in a single-track infinite loop no less). Very frustrating!

Can you make a quicktime movie from a uTube video?

I can watch a particular UTube video on my computers (iMac, Macbook), but not on my iOS devices ('not available on this platform').
Is there a way to download this video in Quicktime, or .MOV etc. format? I'd like to be able to share it with those who have iOS devices.
Thanks for any help of advice!

As I thought. Thank you for the reply Dan. I thought I'd ask in case I'd missed some hidden setting.
