Capturing two video streams via firewire simutaneously

I want to record two videos from two firewire cameras simutaneously to my hardrive directly. I have been able to record 1 stream into quicktime and one stream in imovie hd at the same time without any trouble. Just want to save the space the hd dv format video file takes up. Would buying another quicktime pro license allow me to set one quicktime for one camera and the other quicktime for the other camera. If i can do this would the record setting be best set on mp4 or h.264 if I am editing this in fcp. If this isn´t plausible, does anyone know of software out there that might solve my problem. Can you achieve this in FCP. Thanks Dave

Just click on the QuickTime Player icon in the Applications folder. Command-C to copy it then Command-V to paste it. You now have two copies of QuickTime Player. Open one, set it's input, then open the other and see if you can set it's input separately.

Record two video streams to disk simultaneously

I am recording long conference sessions, with each session up to 4 hours. I have two video cameras (FireWire Standard definition) connected to two computers. When a session begins I record each through QuickTime on each computer. This works beautifully, producing files of up to 50GB with no problem. (I am later combining these with SMIL.)
I am travelling, and I wondering if I can simplify the equipment by recording both streams on one computer. I know this is pushing it but I would like to give it a try. I am using fast LaCie hard disks. I could use two disks connected and put each stream on a different disk.
QT will not handle more than one stream at a time. Is there another application that I might run concurrently to achieve this? I particularly like the simplicity of QT which silently pours the DV format onto the disk.
I tried iMovie, but when I want to get the movie out it takes a while to convert. I am nervous that with big files it will crash out.

Recording video is one of QuickTime 7 (Mac version only) new tricks. It is a very CPU intensive process (capture and encode simultaneously) and even a very fast computer may drop frames.
Version 6 was not allowed to do more than one task at a time. For example you couldn't view a file while exporting another. Version 7 doesn't have these limitations. It can do multiple exports and view multiple files. But this comes at a price as exports would slow down and viewed files would start dropping frames during playback.
Back to your question. QuickTime 7 can only have one capture at a time.
But what if you used more than one instance of QuickTime 7?
Duplicate the QuickTime Player app (Option-drag the app from the Applications folder to your Desktop) to have two versions.
Rename the Desktop version so you don't get confused and open them both. You should be able to now open two recordings but I don't think you'll be able to have two different save locations or camera recoding settings (you might as I've never attempted this).
Don't attempt to use high quality (device native) and keep the capture size small dimensions and it might work.
But it would be easier to record to tape on the camera and edit using iMovie.

External (interlaced) video monitor via firewire?

DSP offers the option of previewing a project on an external (interlaced) videomonitor. But only through an s-video port, which my system is not equipped with... Is there a way to route the preview via firewire? If not, what other options are available?

Please don't take the following as contradictory with your wish, but the truth is that monitoring DVD content over Firewire DV wouldn't be a reliable way, since you would be looking at DV compression on top of MPEG-2 compression instead of a "final result". This may seem like exquisite semantics, but remember that DV NTSC has a 4:1:1 color grid and NTSC DVD is 4:2:0. You would get a very significative reduction in color information. It may or may not be "close enough" for your liking, but it wouldn't be really accurate.
Strange as it may seem, uncompressed boards (like AJA or Decklink) would be the ideal way. Because in this case uncompressed would mean no additional (or different) compression on top of the already compressed MPEG-2 streams.
But yes, both things should be possible. Ideally, MPEG-2 through uncompressed component or SDI. And Firewire DV as a quick and cheap workaround (amazingly, though, Decklink uncompressed I/O boards are cheaper than most DV gear!)
Did you guys send an enhancement request for this through the DVD Studio Pro feedback page on Apple's site? I did that with both hands

Capturing multiple video streams into a movie file

I am using QTKit to capture 3 media streams simultaneously: audio, video, and display (display is screen capture), and would like to capture them in a time-synchronized fashion to a single .mov file.
I have been able to successfully capture these three streams to 2 separate .mov files by using 2 QTCaptureSessions (one for audio/video, one for display video), but the problem here is that the 2 files are not time-synchronized (I have no idea how to synch them after the fact).
The more intuitively correct thing to do is to use a single QTCaptureSession instance with 3 inputs (2 video inputs and one audio) to do the capture, which should automatically synch all the streams. Furthermore, since the .mov file can support an arbitary number of streams, I figured wiring up the QTCaptureSession to output to a single .mov file would be easy. I was wrong.
The problem is that even though my QTCaptureSession has 3 nice input connections (2 video and 1 audio), when I wire up a QTCaptureMovieFileOutput to it, the resulting QTCaptureMovieFileOutput object has ONLY 2 connections: a single video and a single audio.
Here is snippets of what I am doing:
// add audio input: (type of media is QTMediaTypeAudio), succeeds
[qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtAudioDevice] error:&qtError]
// add video input: (type of media is QTMediaTypeVideo), succeeds
[qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtVideoDevice] error:&qtError]
// add display input: (type of media is QTMediaTypeVideo), succeeds
[qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtDisplayDevice] error:&qtError]
// create file output
QTCaptureMovieFileOutput * qtFile = [[QTCaptureMovieFileOutput alloc] init];
[qtSession addOutput:qtFile error:&qtError];
// PROBLEM: if I look at this array of connections, it has ONLY 2 connections
// 1 video, 1 audio!!!
NSArray *connections = [qtFile connections];
// start capture running
[qtSession startRunning];
// wire up to my file
[qtFileOutput recordToOutputFileURL:[NSURL fileURLWithPath:outputFileName]];
I desperately need help....my questions:
1. Since QTCaptureSession supports arbitary inputs, and QTMovie supports arbitrary # of streams, I can't believe it's not possible for me to simply "hook" all the inputs of QTCap to output connections that will write to streams in one movie file. Clearly, QTCaptureMovieFileOutput is not doing this...can anyone tell me how to do this? This can't be hard, right?
2. If I have to fall back on the ridiculous approach of capturing 2 unsynchronized .mov files and somehow synching them after the fact, can anyone provide a pointer on how to do that?
Thanks VERY much!
Steve

Daisy chain two external drives via Firewire, then connect one via USB to the TC?

Hi,
I have two external drives that have both Firewire and USB ports. My 1st generation 500 gb Time Capsule (maybe all of them?) only has USB ports so up til now, I have connected one or the other drive via USB. (I've tried to connect both to a powered USB hub but one drive has problems showing up. At this point I only use the one drive that shows up and connect it directly with no hub to the Time Capsue.)
My question is: Can I daisy chain the two drives via Firewire and then connect one of them (probably the one that has no problems connecting with USB) to the Time Capsule via USB?
Second, somewhat-related problem...
I don't know why one drive isn't connecting very well when directly connected to the Time Capsule. Both are Fantom drives. One is a 1TB, the one that has prblems connecting is a 250GB. I've tried connecting directly or through a powered hub. The 1B has no problems, the 250 gb won't show up most of the time and disconnects itself fairly quickly if it does connect. I've switched cables; that hasn't helped. The 1TB stays connected most of the time but sometimes it disconnects too. I suspect the Time Capsule just isn't able to deal with external drives so I don't puch it. It would be nice to be able to have both drives accessable through the TC though.
Thanks for any help.
Cheers,
John

Doing some experimentation, connecting the drives directly to the MBP:
- Neither of the two drives Firewire daisy-chained and going through the powered USB hub connected to the MBP mount. I was using old aliases on desktop.*They don't show up on network otherwise. (Each drive self-mounts with both Firewire and USB direct connections.)
*Even after making new aliases, neither drive will mount using their new aliases when directly connected (not through hub) with USB or Firewire (and Thunderbolt adapter.) That's weird.
- Both the 240 gb and the 1TB drives going through powered hub connected to MBP mount by themselves.
- Two drives daisy-chained via Firewire and one drive connected to the MBP via Firewire (and Thunderbolt adapter) self-mount. No surprise there but that doesn't help me as I want to have the drives further away from the MBP and connected to the Time Capsule, which doesn't have a Firewire port anyway...
- All of the USB and the Firewire cables work as does the Thunderbolt adapter. I tested them.
I wonder.... I have a Firewire to what appears to be an Ethernet connector. I wonder if that would be any good. I'm afraid to try it though...

Sending video OUT via Firewire to my Camcorder FROM my computer?

Hi all!
Can I send video OUT from my comp. to my camcorder via Firewire. I have a camcorder that has Passthrough to use it as a bridge which I have used to hook up a vcr with. But Im not sure if I can send video OUT to the camcorder and record it on the tape? Any help would be great!

Hi Retha!
Yes, you should be able to do this. Use the Export command in the File menu of iMovie, and you will see that Camera is one of the options.

Any chance of syncing my 5G video ipdod via firewire ?

If I was to get an older ipod firewire dock, and use the included adapter plate, can I sync (and charge) my 60G ipod/video via firewire ? I am running out of USB ports and don't have room for another hub, it's a pain plugging and unplugging. I do have an unused FW 400 port. Any advice would be appreciated, I do realize it is not officially supported. But will it work, has anyone tried ?
Thanks.

OOPS ! Wrong forum, I see my question is being rather hotly debated in another forum here. I am guessing the answer to my question is NO ! Sorry for the mis-post.

Video out via firewire

Is color capable of outputing preview video through my DVCam deck via firewire? The option in the video out preferences seems to be grey out as are the other options in there.

I had forgotten I'd posted this and I need to make a clarification.
At the time of this posting, I'd been assured by Blackmagic Designs that Color would preview externally through their Intensity Pro card although in 8-bit video. Since the time of this posting and upon further query with BM tech support, I was told the Intensity Pro could not be used in this function.
Sorry if there has been any confusion caused by my statement.

Live Capture from GL2 Camera via Firewire

Image quality when capturing live video into iMovie from a Canon GL2 is very very grainy and poor quality. It used to work fine capturing into iMovie HD, but that no longer works correctly with Snow Leopard (transport controls and other buttons don't show up). The footage is totally unusable.
I've heard that image quality in iMovie is a bit less than FCE, but this is no minor difference. Is there a setting that should be changed?

t used to work fine capturing into iMovie HD
iMovie 09 uses 'single field processing' meaning every other horizontal line of the video is thrown out, which reduces the sharpness of the footage.
iMovie 06 (iMovie HD) uses ALL of the image to form the video.
no longer works correctly with Snow Leopard (transport controls and other buttons don't show up).
I use both iMovie 09 and iMovie 06 with OS 10.6 (Snow Leopard). (But when I need better quality I use iMovie 06.)
I've heard that image quality in iMovie is a bit less than FCE, but this is no minor difference.
iMovie 06 and FCE have the same image quality. iMovie 09 uses 'single field processing' so you have a bit lower quality.
Is there a setting that should be changed?
No.

Video Streamer Via Internet

Hi, I scoured the forums and couldn't find anything that really satisfied my question: Can I stream videos over the internet without encoding anything?
For example, I want to stream my library of about .75 TB from my computer at my college apartment to pretty much any other place I'm at, with no (or minimal) encoding. On the fly encoding would be possible to do since my computer is pretty beefy and should be able to handle it.
Linux to Windows would probably be preferable.

Video camcorder via firewire

I am looking to buy a camcorder as a christmas gift for myself but am stuck deciding which to get. My main concern is that it must have a firewire connection. Price is not an issue ... I just need one that will connect via my firewire port on my G5.
suggestions ... anyone?

Get the sony handy cam dcr-trv460. It records on tape, but you can also (with a memory stick) Take digital photos. You can use iMovie to view the video recorded on the tape and all you need is the firewire cable. (It doesn't come with a firewire cable.) I purchased this camcorder last year and it is a good camera. It's easy to use, and it has good picture quality. It's a bit expensive though. about $350 in the US. I paid $400 for it two years ago. (august 2004) Hope you consider this camcorder as I'm an experienced camcorder user. P.S. You can get any brand camcorder you like, just not JVC. They get Terrible reviews on all their video products, mainly camcorders. -Trevor129

Live Capture with a camera via firewire and usb audio interface

I am trying to do a live capture through Final Cut 7.
I want the video feed through the firewire from my HVX200 and the audio feed from a 4 channel usb audio interface (Alesis iO4).
When I have both audio and video input coming in from the HVX200, the live capture works fine.
However, when I change the audio input so that it is coming from the usb audio interface, final cut has an error message saying "Video is not available."
During the preview, I see the video clearly and am getting levels from the iO4.
But when I try to capture, I get the error message.
Is it a processor issue (I've attached my specs below) with problems handling 2 separate inputs?
I'm not quite sure what the problem is.
Any input is greatly appreciated.
Thanks!

Hi MtD,
Yes I am changing the Capture preset to iO4. Once that happens, it lets me run both the camera and the iO4 into the laptop but then an error message pops up the moment I try to capture it.
I was only trying to use 3 out of the 4 channels of the iO4.
Thanks!

Video input via firewire

This seems to be a common question with only expensive solutions.
It cost me $40.00 (Canadian) to export video from iBook to TV via 'Apples Video Adapter Kit'. But it's going to cost about $200.00 to get video into my iBook via 'MyTV' or 'EyeTV' type products?
There's got to be a cheaper way but I can't find it.
As far as I understand it's even more expensive, about $350.00 or $400.00 to input video through Firewire, but appearantly that's the only way to record live to iMovie.
I bought an iSight, and it's wonderful, but it's not like I can take it camping without the iBook. lol
Anybody have a cheap solution? I'd settle for video in USB at this point and worry about Firewire later.
Or simply correct my ignorance.

Hi Q_ball,
What exactly are you trying to do? Do you have a video camera that you want to put the media on the iBook? Are you trying to get TV on your iBook?
"It cost me $40.00 (Canadian) to export video from iBook to TV"
Yes, this to mirror your iBooks display on a TV. The eyeTV is to take TV shows from the TV (analog, cable, etc) and put it on your iBook. The newest models let you also hook up your game console.
"As far as I understand it's even more expensive, about $350.00 or $400.00 to input video through Firewire, but appearantly that's the only way to record live to iMovie."
I am sorry, what are you talking about? Where do you get these figures? Are you talking about getting it from a video camera? Most video cameras have both FireWire and USB 2.0. iMovie works seamlessly with FireWire camcorders, but USB is a different story. Do you have a camcorder or are you in the market of buying one? I hope I don't sound rude, I just don't understand what you want. What are you trying to accomplish exactly?

Missing video device via firewire

hey all,
my fc 5.0 has a weird problem.
yesterday, i was batch capturing from my panasonic nv-gs280 (connected via the front fw port), and everything went fine. but as i was trying to edit the final version to video, suddenly, final cut didn't find my camera (missing video device). i tried plug/unplug, restart, etc. several times, but it just didn't work. i also tried print to tape, but the camera didn't get the signal. i also made an attempt to capture, but it failed (same problem).
could anybody please help me?
thanks,
b
