That depends on how much room you would like to use to rehearse in, and how many collaborators you would like to see on screen at once.
Unlike physical spaces, CdnStudio is only restricted by the number of pixels in your studio. While creating a realistic blend of full-body performers is one way to use CdnStudio, we’ve also had success blending users sitting in chairs, using a mix of puppetry with real-life performers, and other creative arrangements!
If you want a realistic blend of full-scale performers, you will want to allocate identical amounts of space at each participant’s location. In addition, we would recommend that:
- The camera you use at each location be similar in resolution and angle of view
- The green or blue screen you use should fill the camera view entirely
- The camera, background and space be positioned in similar or identical ways.
Latency or delay is the time it takes for video and audio to travel from you to our servers, and back to each participant in the studio.
If you have ever used Skype or FaceTime to communicate online, CdnStudio can experience latency in similar ways, where the response times are not as immediate such as in a landline phone call.
A number of factors contribute to the overall latency in your CdnStudio call. While there are some inherent delay times in the encoding, transmission, decoding, chromakeying, blending and return path of the communication, there are some things you can do to achieve best results.
- Avoid using Bluetooth or other wireless headsets in a CdnStudio call. We found Bluetooth devices can add up to a full second or more of audio delay to a conversation.
- Skip the WiFi, if you can. Using a wired connection directly to your internet connection will achieve best results. If you must use WiFI, try connecting to a 5GHz network instead of 2.4 Ghz network. Consult your network administrator or router manual for assistance.
- Check your connection, for network latency using SpeedOf.me. Ideal latency is less than 50ms Some connections like satellite, fixed wireless and cellular networks do not provide low latency connections ideal for CdnStudio.
- Keep your studios small. The more participants you have in a studio, the more latency is compounded as our servers wait for each user’s audio and video to arrive before they can send out the resulting mixed session. If one collaborator’s connection is poor, the entire session will be poor as well.
Any webcam is supported, including built-in webcams. You may, however, wish to use an external webcam or video source to have better control over where your camera is positioned and controlled.
Depending on how much space you are hoping to occupy with your studio, you may want to use an external webcam or video camera mounted to a tripod to have better control over the framing of each studio participant.
External webcams are also often bundled with software that allow you to control the colour temperature, auto focus and exposure settings of your webcam, which can be very useful. If you are using a Mac, you can check out Sight Control ($6.99) or iGlasses ($19.99) to control settings on your built-in iSight camera.
To use the HD feature on your PRO account, all participants must be using a 720p webcam or better to achieve an HD studio session. Links to HD webcams are listed below.
Click the Browse… button in the Studio Control Bar and select a PNG or JPG under 2MB file on your computer. Click upload, and wait for your background to appear. It takes a few moment for CdnStudio to prepare your background and apply it in your studio session.
Backgrounds are automatically sized to fit into your studio.
The standard resolution is 640×480. This is for performance reasons but also to ensure compatibility with a wide variety of devices. Not all devices can do higher or wider resolutions and we have to use the lowest common denominator to make sure the frames stack correctly with similar “scale”. Anything larger will be sized to fit inside this resolution, with black bars on sides that are not within this aspect ratio.
For a solid background, we’re looking for the pink candy stripe to be even and strong throughout the entire background to ensure the best quality of video and background. The more evenly lit, with less shadows, the better.
We recommend using a green screen, but you can also use any bright coloured wall. Blue and green work best, as red and other warm colours can conflict with skin tones.
Creative use of shower curtains, bed sheets and towels also work well, although brighter colours work better than darker shades.
You can order a green screen kit on Amazon, such the ones below.
