Capacity question for participant live video

The marketing for Adobe Connect shows 15 people online with video at the same time. However, an administrator at my institution says that having more than 5 or 6 people can become problematic. What are your experiences with capacity, clarity of voice, noise in background, etc.? How many people can I expect to have live at the same time on video?
thanks

It all comes down to bandwidth. Since there is no limit on how many individuals can be sharing their camera and audio, you should be able to share as many as the internet connection can handle. However, there is a line between possible and reasonable.
You should be able to accommodate more concurrent live videos than concurrent live audio streams.
When breaking the 5-6 number for live video, I'd switch down to the lowest quality video, so that I have a better chance of getting the clean videos delivered to everyone. Consider whether or not everyone needs to be on a live video stream. Do you need to see people sitting there drinking water, picking their nose, or looking bored? Usually only the individuals that are actively speaking justify a live video.
Audio through VoIP is like audio through radios. There is a single audio stream and everyone's audio gets compressed into that single stream. So if you have more than 3-5 individuals talking, it will just sound like noise with no easy way to distinguish one person from another. If the group is well behaved you can get more people to have hot mics at once, but only one or two people should be talking at any given time. Additionally, multiple hot mics will increase the likelihood of an echo or a feedback loop. Like the video, only the individuals who are speaking should have their mic on and broadcasting. This is why the raise hand feature is in Connect, so other individuals can indicate that they have something to say, and the host can give them the ability to do so at the appropriate time.

Can I connect an external video camera to a mac book pro for viewing live video so I don't have to use the little screen on the camera?

• Only if your video camera supports it. Depending on how your camera works, you may need to add preview software to your Mac to use this feature.
• Alternatively, your camera may also be able to record directly into your Mac while you are monitoring the Mac's display.
• If you are using a consumer camcorder that supports HDMI monitoring, a small HDTV might be an simpler solution than your Mac. For an example of how this is done, see http://youtu.be/GVpSkZD6qE4.
• The retailer who sold you your video camera may have other suggestions.
• If you need more professional results, an external preview monitor will offer more capability on compatible cameras.

New Sequence Question - for slow motion video

Hi,
I'm a very new user of Premier. I've recently had issues with choppy playback of my preview videos. After much research I believe the issue was down to two things. Firstly my sequence did not match my input clip, I had it set to my desired output. Secondly, I was editing video across my network, rather than bringing it locally to my PC. I've fixed the latter issue by copying video files to my local machine and then moving them back onto the network once I've finished editing.
The advice out there essentially seems to be to match your sequence to your primary input video. I've done that and it helps. However, it's raised a big question for me. My input video is from a GoPro and is at 1080p 50fps. I ultimately want my output video to be slowed down to 25fps (resulting in a constant slow motion effect throughout the entire sequence).
If my sequence settings are set to match the input clip (50fps) and I slow the video down by 50%, will that result in an unsmooth video? My basic understanding is that if I slow 50fps video down by 50% then Premier will have to double the amount of frames. Where as previously, if I slowed it down by 50% Premier had enough frames to play with as the output video was 25fps.
Hopefully my question makes sense! Any advice on what the best approach is? Or is this a complete non-issue when it comes to exporting the video (providing I export to a 25fps formart)?
Thanks,

I think you said it OK, you are just missing the right words to do what you want. Let's walk through this for you, and for others that might read it later.
If you take a 50 frame per second video and put it into a sequence created from it, then slow it down 50% it doubles up each frame to achieve slow motion. Not what you want.
If you take a 50 frame per second video and put it into a 25 fps sequence, it drops half the frames to play at normal speed. Not what you want.
What you want to do is interpret the 50 fps video to 25 fps, then drop it into a 25 fps sequence. Each frame will play at 25 fps and generally be smooth as silk.
I don't have any 50 fps clips handy, but here are examples of taking 60 fps to 30 fps. (Excuse the idiot way that we Americans do things. Our 30 is actually 29.97 etc)
First, right click on the clip in the Project Panel, select Modify, and Interpret Footage. Then change the 50 to 25 - similar to this image:

Question about Steaming Live Video...

I am developing an app that streams a live video feed from one of our basic webcams... Would this work well if the other user was on a dial-up connection, or a slower connection?
How is the video buffering and loading supported in flex... ??

The streaming process is handled your the streaming server, usually
the streaming server has several algorithms to detect bandwith and
lower the packages or increase the packages that are send to the user.
Sincerely,
Michael

Please help me with this urgent viewing and editing question for a long video clip.

Hi, I have never used this software before and when I imported a 2 hours and 12 minute video clip of my sister's wedding into the system and added it as one sequence into the program it would only allow me to watch and edit the first 2 minutes.
Why is that and how can I rectify this so that I can watch and edit the whole clip?
Also, can such a long video clip be edited by trimming it and creating transitions where I see fit?
Thanks so much for your advice as I am feeling really stuck right now.

Driver question for SoundBlaser Live 5.1 card installed in D

Greetings:
I have just completed a clean install of WXP and SP2. Is it better to use the SoundBlaster 5. driver on the Dell site or the one on the Creative Labs site? It looks like there are several to choose from on the Creative Labs site. Can someone please indicate the proper choice?
Thank you.

Thanks Shingo-Y:
I saw a driver on the Creative Lab site listed as SoundBlaster 5. Li've for Dell and thought this might work but perhaps I should play it safe and just install my original driver from the Dell CD.
Thanks for your reply.

Using FCP for live video feed

Hi,
I'm currently shooting with the new HVX200 Panasonic camera. We're using a small, 7" hand-held HD monitor to use for focus-pulling, but I'd like to be able to use a computer monitor or laptop for a live video feed. (director's monitor)
We've considered using the component-out to go into a Component-VGA adapter for a computer monitor, but I'm wondering if we can do a direct feed using FireWire into FCP or something.
Anyone have any experience doing a computer-monitor setup for use with these kinds of cameras?
Thanks for the help!

hey there RI,
if you've tried something similar on your iMac & had no problems it's reasonable to think/believe it will work on your MBP, w/ this caveat: the 400 & 800 ports are actually on the same buss, so the 800 port will handle it's data at the lower(400) rate if there is a device on each port. shouldn't affect any editing w/ the drive once the cam is removed from the MBP. it should the run @ the higher rate.
good luck.

Streaming Live Video to I-Phone

Are there specifications for streaming live video to I-Phones?
I work for a webcasting co. and we would like to offer our webcasts to our clients via their cell phones. I haven't been able to find any documentation relative to live video streaming to an I-Phone.

Hi,
Since the iPhone browser can play MPEG-4 movies, it should be able to play streamed MPEG-4. Flash and Windows Media isn't an option.
Fortunately QuickTime Broadcaster is free, but you'd need a QuickTime Streaming Server to "bounce" the stream off. Setup Broadcaster to do an MPEG-4 video that's within the playable specs (given that it's a live stream, you'd want something as small as possible, so I'm sure the iPhone could handle it). If you're wanting your clients to access the stream over 3G as well as WiFi then you'd need to keep that in mind when determining the video size/bandwidth.

Selecting the best live video production set up!

I am currently an art director but have worked with television and video depts. in the past. I have been asked to head up a new dept. at my church. I am looking for the best set-up for doing live video to record and do all the media, lighting, projection and sound also. This would fall under the current "House of worship" industry but I also will be doing full video and short film, and instructional video.
I would really like to be at a professional level but keep the budget at a doable amount.
I have been having trouble searching this online.
I would really appreciate the opinions of any professionals in video production at this level.
I will be giving recommendations to purchase the necessary equipment and software for this endeavor.
Thanks.

I simply meant configurations that include Apple as the CPU and software of choice. I realize the other components involved basically but I am trying to get the biggest bang for the buck.
I am having trouble finding a consultant in my area.
My concern is buying into something that will become obsolete and not be scalable.
With Mac I know scalability is no an issue. With the other needed equipment I'm not so sure. I have to start fairly small and add to the set up as I go.
I need to start with the ability to switch between 3-4 cameras. We are using old Canon XL1's at the moment so most likely we'll run analog cable. We are looking at a Videonic M4 digital switcher. (I'm not sure of it because it's prosumer and maxes out on sources fast. What I would like to do is be able to switch between 4-6 cameras and have a worship music presenter with the ability to run mpegs and control lighting.
Any ideas on getting this up and running at a smaller level and then working up? I could start with 3 cams but would like to do the rest as stated.
Thanks.

Live video for presentations

Hey guys,
i hope you understand my question:
I know, that the Socialize webcam got a feature, you are able to create live videos while a picture / (powerpoint) presentation is running. So you can talk next to the presentation and everybody see you in a small window in the right edge of the video. Does this function run with theOptia AF II, too?
Thanks for help.
Greets, misorx

Even if I have a HDMI output port and a\v output?
If so what kind of equipment do I need to do the job properly?
