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.

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,

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

Capturing Audio and Video of DVD

I need to convert sections of a DVD (audio and video) that I narrated on to mp3/mp4 so I can put it up on my website.
Is there a way to do that with Quicktime? Some plugin?
Thanks
G4 Powerbook Mac OS X (10.4.8)

Is there a way to do that with Quicktime? Some plugin?Not normally. While there is an MPEG-2 QT component for the video data, it ignores the audio. I would normally use MPEG Streamclip (free) to demux the audio data to AIFF. This is a very quick operation. Since the AIFF file is fully compatible, it can then be converted to other audio formats by QT Pro and/or iTunes.

Audio and video to different drives?

Hi
I have HD footage from Final Cut Pro on a RAID and want to mix the audio in Soundtrack Pro.
Is there any advantage in storing the audio on a seperate drive? This was not recommended for DV
(though I'm not sur why).
Thanks

I used to live in France and used LaCie firewire disks a lot. Now I use ICE & ALUICE which have the Oxford bridge.
Your 2 X 500GoFirewire in RAID 0 will only give you a theoretical 1.6 Gb/second,
so I think your occasional problem comes from that. Even with only one video track, if you have lots of audio, try keeping it well de-fraged.

Airplay both audio and video through different devices

When is it gonna be possible to airplay audio on my Bose Airplay Speaker and the video on my TV? Is it about the update of the iOS?

This is a user forum so no one can answer that. I wouldn't count on it though.

Capturing Audio and Video Directly to Mac Pro

Is it possible to create a video by recording directly to the Hard Drive via FireWire?
I have a Mac Pro - 10 gigs of Ram, Quicktime Pro, Final Cut Express, Imovie.
I need to make some training videos that will be posted to the web and would like to streamline the process and record directly to the computer. Would like to create best quality possible but still go direct to the computer.
Can you suggest a camera (need good audio too) and application.
Thanks

find a discontinued iSight or choose from any of these
regards,

I have old IPad and down load new software. It completely distort my ITune set up. I use to have audio and video in the ITune, now it's separated audio and video in different category. And I can not set group or alphabetical tap to pull out video.

If set them up in the group sush as; comedy,action,drama,ect. It would be nice.

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

QT audio and video clips on web site not playing

Hello,
I recently did a clean new install of Leopard 10.5.8 and since then there is a site I used to go on that played QT video and audio clips just fine, but now, although the QT symbols are present, neither the audio or the video clips operate.
The clips used to just load on the site automatically and they would operate when I clicked on PLAY before I did the new install.
I've downloaded the latest QT Player, Version 7.6.2 (518).
Here is a sample page, it's a Japanese language learning site - when I open this site I can only see the QT symbols where the video and audio clips usually load - but you will probably see the actual clips load just fine if your system is working OK.
http://www.dartmouth.edu/~kanji/kanji0301.html
It's a great site when the clips are working but it's not so useful when they don't.
I've written to the site's webmaster - they don't reply - tho' I don't think it's anything wrong with the site since it only went wrong after I did a new OSX install, I think there's a switch somewhere on my system that needs activating.
Can anyone help me get these clips working?
Thnx a lot.
Ann

You going to some how get in contact with the site's webmaster. I know you said you tried but the webmaster can only answer your question about the Qt videos. I tried to load the URL for the video into the Quicktime Player and all I get is ... The URL is not valid alert box. I even tried it in Firefox, didn't work.
It the site that's having problems and not something on your part. Installing your OS didn't cause this...

Audio and video clip lengths differ in encore timeline

Hi
I have been working to build a BD-R H.263 ac3 disk. I used AME from within Premiere Pro to export the M4V and (at the same time) AC3, using the present defualt parameters-no tweaking of any setting. The clips appear to play great on encore's monitor--everything in sync.And on the burned BD-R
However, I am getting the black screen between clips in the timeline when played in the standalone BD player, or (when I had one clip to a timeline) in a playlist. a previous poster made note of different length audio and video clips. I zoomed on the timeline and lo and behold--the the audio and video clips are different lengths.
This is with the timeline fully expand--each division is a frame. Note that break between the two audio clips is offset from the break between the two video clips by two frames. This offset is after several clips. I could find no information on what the one frame crosshatching at the end of the leading clips means. Can anyone explain this cross hatching? What do I do about it? the image below is after the first clip in the timeline:
In this image, the offset is less than a full frame??????
I tried using the trim tools to bring these together-but, the trim tool only lets it jump a full frame and then only to a GOP boundary, which doesn't help because the boundaries are obviously different fro the video and audio track.
I want to emphasize that these assets were created from the Premiere CS4 timeline (which had no offset between audio and video) using the default H.263 and AC3 presets in AME and the same presets selected in Encore.
The offsets do not appear to cause the actual audio and video to go out of sync when I play the burned disk. But, I get the 1-2 second wait between menus and chapters, or with items in a playlist.
The audio offset suggests that the player may not know what to do when faced with a chapter point that is different on the audio and video tracks, although, I will note that encore snapped to the joints in the video track not the audio track.
You can see from this listing that several of the clips audio and video lengths that differ by one frame. By the end of the timeline, the cummulative offset is 3 seconds (48 minute timeline)
Can anyone shed any light on this? Thanks

I don't think that I had the same problem that you do, but I thought I'd throw in my two cents just in case it might help. Encore would not build the output; it said something like the inpoint and the length did not match the endpoint. Actually, I think this happened in several different situations. In one case I simply adjusted the audio and video tracks to match endpoints. In the other case I went back to Premier and found that in some cases where I had added transitions it had shifted the endpoints of the audio and video tracks so they did not match. I removed the transitions. It didn't matter that much to me since I'm doing this for personal use. Is it possible those crosshatched lines you're seeing are transitions?
I am using CS 3 and editing HD. I have had many problems with encore. I read in the form someplace that it had a hard time handling H.264 so I changed to MPEG-2 and that fixed one problem. In another case it couldn't find some files and I found some advice not to use HD or wide menus, so I switched to standard 4:3 menus and it worked.

Multiplexing audio and video streams,,,,,,,,,,

hii frnds,,,,,,,,my proj is "Web Conference" ,suppose v capture audio and video streams separately from MIC and webcam respectively now how to multiplex this into a single stream so that i can later upload it to a server and from there clients can download as a single stream and later demultiplex at receiver side

I am programming the videoconference program using Java Media Framework API. I use two session to transmint and recieve the media, one for audio and one for video. Two players are opened to play both media. I would like to know if I can play both media using only one window.

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
