OBS Studio was developed by a worldwide community of volunteers. The project was started in 2011 by a German developer named Sebastian Mauer, who other developers from different countries later joined. The project’s source code is hosted on GitHub, allowing anyone to contribute to the software or report bugs. OBS Studio has been downloaded millions of times since its release in 2012 and has been translated into more than 40 languages. To use OBS Studio, open the software and click the plus button in Sources: one can choose from RTMP Encoders under StreamingVideoProvider Live Studio. After opening settings, go to Stream and select Custom from Service drop-down after switching to Stream. Go to StreamingVideoProvider: live Studio, copy the RTMP URL and Stream Key and go back to OBS Settings. Next, click “OK” on the settings, and the live stream preview will be visible in the Streaming Video Provider: Live Studio. In the final step, one will only need to click “Start Broadcast” and start the stream.ĬamTwist Studio is a free software that allows users to record and stream videos in high quality. The software is available for Windows, Mac OS X, and Linux operating systems. #Camtwist compatability for androidĬamTwist also has a mobile app for Android and iOS devices.ĬamTwist is a highly interactive live streaming application. It looks like a promising cross-platform solution, but we have yet to evaluate how it fits our need.The software supports 720p resolution if CamTwist has an input card and can function with the 1080i level. If you prefer an operating system other than Mac OS X you might want to have a look at the Open Broadcaster Software project. If you prefer to record it yourself just use your streaming and recording software on the same sources in parallel. We usually rely on Google Hangouts on Air, which also offers a recording of your live stream after the broadcast has ended. If you instead want to live stream your presentation head over to your favorite streaming software and select CamTwist as video and the USB sound card as audio input there. So instead of your HDMI grabber select CamTwists virtual camera as video device and the USB sound card as audio device in your recording software and click record, then manage the video composition in CamTwists studio screen. It not only accepts video and audio signals but also lets you add digital on-screen graphics (DOG/bug) and offers various effects to dissolve and fade signals. CamTwist is a free software available for Mac OS X that lets you manage and compose several input signals to create a single output signal, registered as a virtual camera device. To compose both video feeds and the audio feed into one stream, we recommend CamTwist. Instead of recording the presenter on a separate camera, use a high quality webcam and connect it to your recording computer. So you want to minimize the time needed for post production or you even want to stream your presentation live over the internet? We got you covered: For ways to integrate a video feed right into the recording refer to the next chapter.Īdvanced video recording and live streaming The video of the presenter is recorded separately on a regular video camera and later edited into the video, e.g. If the wireless microphone is tuned correctly you shouldn’t have to change anything, but in case it isn’t you might want to test the interface’s settings before starting the actual recording. In your favorite video recording software select the grabber as the camera and the interface as your microphone-we used Quicktime on a MacBook and it worked like a charm. With the presenter’s computer plugged in, connect the USB Audio interface and the HDMI grabber to your recording computer. Now that we got everything we need, let’s start recording. There are several output ports, one of which is wired to our speaker system, so we don’t have to worry about getting an audio splitter, too. To record the audio from our wireless microphones we bought a USB Audio Interface and plugged it into the output of our wireless receiver. We also got an HDMI Splitter, so we could grab the video on one laptop and loop it through to the projector at the same time. The dongle doesn’t require any drivers and registers itself as a camera on Windows and Mac OS X. So we decided to get a video grabber-Magewell’s XI100DUSB-HDMI Video Capture Dongle has quite a reputation with VJs, so we got it on Amazon. However, we had no way to actually grab the signals without interfering with the presentation itself or installing software on the presenter’s computer. Our starting situation wasn’t the worst: The office already had 2 projectors, 1 Screen and 2 wireless microphones wired to a Crestron system which provided us with a single place to grab audio and video output.
