That is why I am searching for a Device that can ALLOW me to connect the LIVE VIDEO INPUT to the computer
And what TYPE of input would that be? What is your LIVE camera output?

I know i can plug directly to the projector. But I am trying to do a Picture to Picture effect. That is why all input has to go into the PC.

I have bought Avermedia USB TV tuner, it fails. Probably its because of USB 1.0

Anyone has any recommendation?

Live input is from a RCA jack.

You're not going to get DVD quality from RCA connections, I would imagine that any video output via Analog video camera>RCA>PC>Projector>400" screen is going to look like crap no matter what you do.

Any PCI capture card with composite video input should work OK to get the feed from your video camera into the PC. I don't understand the picture in picture you are describing however. Lets say video camera input is Picture #1....what is Picture #2 for your Picture in Picture? How are you connecting the PC to your Projector?

Can't you just plug this "source" straight into the projector?
Quoting myself because I think it got missed....
Why does it even have to go through the computer AT ALL? Are you recording it at the same time? Doing some nifty computer tricks at the same time? Unless you're doing something really nifty that NEEDS a computer, why not just hood up this RCA source up to the projector directly??

get a firewire or cardbus dvd drive. that way you'll get full quality dvd playback, full animorphic resolution.


with a tv tuner you'll get far less resolution, and garbled picture considering its been converted back and forth, plus tv cards aren't made for dvd quality, just broadcast quality. bad idea indeed.

He doesn't WANT a DVD drive... he's getting video from a camera and displaying it on a projector. We still don't know why it has to go through a computer at ALL. [shrug] But a video capture device would probably do better than a TV tuner would.... if going through the computer is required for some reason.

OK, the reason that i am doing this is because we want to put powerpoint presentation and live video feed on a very large screen at the same time.

By plugging directly to the projector, I would have to be at the projector and change the source with the remote every time I need to. And it takes a while for the projector to change source and plus, it would have a blue screen when it change.

That is why I need to divert the live video into my computer so that my powerpoint presentation would lies in the background while the live video feed would be on top of it. either full screen or a small screen.

sorry for not making clear. Thanks

I just bought another Pinacle PCTV. Its use USB 2.0 and allows Mpeg2 input, no idea yet would it work good or not, will post it later after i test. But please do make your recommendation if u have one. :)

thanks

The 2-3 seconds of blue screen during the change is not that big of a deal, especially if you can make the switch on the remote! What were you planning to do? Have a page in your powerpoint presentation link to a video "window"? I don't think that can be done live - PP just isn't that clever.

Mac has a presentation package that kicks the stuffing out of PowerPoint... I wish they'd bring it to PC! :(

Don't worry about the problem of linking live video to the PP. I have already put flash into my PP. and we already done one function base on the PC, just that the avermedia quality is too low.

In big function, having blue screen is a big problem. Furthermore, we are having rear projection while I am situated in the opposite side of the screen. Far away from having the ability to switch source. And worst, the projector has 3 input, it gave us problem when choosing Input 1 and input 2. meaning longer blue screen.

and the main reasons that we want to do this is to be able to put picture in picture effect.
picture 1, background Powerpoint.
picture 2, small window, live video feed.

What do you mean by video captures? The thing is, it need to have features like TV tuner in order for it to work as if I am not mistaken, the video captures that u are talking about is those which only works on editing software.

Somehow I don't think so... My friend used a video capture card for YEARS to hook up his video camera and use it as a really high quality webcam (better than any that yave yet to come out!) I can't see why your PowerPoint video window can't take live input from a video capture device - seeing as how you were able to get it to take in a TV tuner!

The video capture device will look better... then again, are you just chasing after a quality that won't really be noticed? If this is for a big audience, they'll be sitting at LEAST 10 feet away from any screen... so long as the quality doesn't *suck* it should be adequate.
Unless you're really, really trying to sell "quality" to these people... like a business meeting or a product selling demonstration.....

No, I am not selling quality.

U see, the video capture card must have a TV Tuner software to support what i need to do. Most video capture card they only work with editing software like adobe premier. any idea?
