Recording High def and projecting analog

[Nicksterblessed]

My pastor has informed me that he wants to utilized the big screen behind him used for worship lyrics to project his image to make sermons a little more personal. we are currently using Songshow as a media software and i am not aware that this software has the ability to record life and project live (video) at the same time. Any suggestions?

I just glanced at the feature set for SSP and did not see a live interface for video content.

Depending on how you want to do your live video, you have a few options. The most complex and probably expensive would be to do a multi camera shoot with a nice switcher. Panasonic has a 4 input switcher that would work nicely for this and still be reasonably priced.

You could change your presentations software to one that includes a live interface. You should be aware that there are usually latency issues with this kind of solution.

The last solution is to run a dedicated video line to your projector for your camera and do the switching at the projector. It ain't pretty, but it works and it is usually the least expensive option.

Hope that helps, or at least gets some discussion going.

I'm not aware of a computer solution that does this well. The only solutions I have seen that actually work always utilize live switchers.

[Nicksterblessed]

Well I think that i have come up with a no cost solution. SSP allows for live broadcast with text overlay. The camera that we are utilizing is a tape record camera. So we will be recording and broadcasting at the same time with these features. I have found that in the past 24 hours and in talking to 2 major software manufactures that it is very expensive to get a capture card and module(Software)to add to SSP. So I think that I will do it in a old fashioned way. Seems that the old fashioned way is the cheapest way as well. God Bless ya!

P.s any more comments are welcome as i like to read input from everyone.

How are you going to get the live video into the SSP computer?

[Nicksterblessed]

Petereit: via firewire

[petereit]

Do you realize that video through firewire is not "live"?

[[Admin] osborn4]

If you want to use SSP with no latency video, you should look at their DeckLink support.

Using firewire, as perereit inferred, will produce a bit of lag.

[shortcircuitcg]

I have tried the FireWire route and can verify a 1 to 2 second lag.

[Nicksterblessed]

I have determined that firewire is not the way to go for live broadcast on the screen behind the pastor. Thanks for all your input. petereit: I understand the lag now and with the research I have done I need to upgrade my whole system. The camera I am using now has a firewire output and analog output This is the camera that i am using now...Sony Handycam HDR-HC1. osborn4: Depending on the kind of slots that I have available in my computer I am going to purchase a decklink intensity pro. If I dont have that slots available then I will build another PC. My question to you all is, What kind of camera do you recommend. The camera that I will purchase has to have 3 things at least(unless you suggest something else) 1. HDMI output 2. 120 zoom as the camera is mounted 50 from the stage. 3. Mic input from the sound board to the camera. My price range is about 1500.00 for the camera.

PS. Do I need some kind of compressor/limiter to go inbetween the sound board and the camera? Please suggest.

I'll share my story as it may help you... going from SD to HD while preserving latency is not trivial... our church decided to upgrade from analog NTSC Sony PTZ cameras to a full HD system.

I purchased:

4 Canon XH-G1 cameras (with GENLOCK and HD-SDI out)
1 Datavideo SE-2000 (HD-SDI mixer)
1 Blackmagic Multibridge Pro (HD-SDI capture device)
2 Benq 4000 lumen HD 16:9 projectors (HDMI input)
a few AJA HD-SDI to HDMI converter boxes HA5 / HI5 etc


... the stuff is in my living room right now I am still troubleshooting with it because there is noticeable lag/delay/latency whatever you want to call it... between the camera and the projector.

For IMAG (live presentation of your camera feed) purposes you don't want this delay.

At first I thought it was the video mixer or the converter boxes or possibly even the 1080p Sony TV I was using to output to... so I decided to eliminate all the possibilities and go Canon XH-G1 camera straight to TV / PROJECTOR etc... and there is still a noticeable delay (approximately 150ms ... I timed it)

I started doing some more digging on these XH-G1 cameras and it is a shame... they take such amazing shots and record soooo well but for HD LIVE needs... don't seem to do so well... even with a $30K broadcast pix slate system there is still delay... not sure how to resolve the problem... I am currently looking into different camera options... hoping to find the lowest latency HD camcorder on the market...

Good luck with the build... like I said going from SD to HD and preserving end to end latency is not trivial.

We have great response from our JVC GY-HD250Us. They were designed to be used as a live studio camera. Even frame-buffered through our Panasonic AV-HS300 switcher, converted through an AJA SDI-to-HDMI converter and scaled in our projectors, we get virtually no latency. There's some, but you pretty much have to be a video professional to notice it.
