![]() ![]() On the Controller tab, select the Produce with controller option. Select MP4 Smart Player (HTML5) and click Next. If nothing helped please check if your microphone is connected. Select Custom production settings from the dropdown and click Next. In some cases you will not see a line before making a relatively loud sound into the microphone. Choose External Microphone (in System Prefs), turn up volume and use noise reduction. To customize Smart Player and export your video as an MP4 file: Click Export > Legacy Local File.If you hear background buzz in your recordings, use Copernicus.On computers other than Copernicus, the microphone selections may be different (on my MacBook, System Preferences only listed External Microphone, and Camtasia only listed the Built-In Microphone). Make sure you have the correct devices selected. In Camtasia, however, the ModMic is referred to as the Built In Microphone (as opposed to Built in Input). You can select "reduce background" for that device, and turn up the volume. When pairing on Copernicus, System Preferences refers to the ModMic as the External Microphone. So, if you can pair the ModMic on your computer, listen to make sure there is no background buzz. Most Macs have built-in microphones, but if you prefer, you can also use an external USB microphone plugged into your Mac. On some Macbooks, even though it pairs correctly, the ModMic has a buzzing in the background. Some additional documentation on this issue: The bumpers have a vertical dimension of 720px, so this seems to be an acceptable resolution, but it may require that we recommend to anyone needing to borrow a laptop to go with the modmic should use Safari only for recording. Notably, recording on the Macbook Air results in lower resolution screen capture video (max 1024圆70 in Chrome or FF since the address bar can't be hidden max 1097x718 in Safari - and must hide the OSX Dock to save vertical space). If the buzzing sound persists after doing so, it might be an electrical noise emanating from the ground loop or USB hub. It's difficult to document a hardware model year after which the Macbooks will guaranteeably recognize this input (since the Airs seem to do so as early as 2010, while even a mid 2012 Macbook Pro 15" won't). Try to reduce the gain settings to a manageable level. Erdos and Bose are the same model year as Dirac, and Copernicus is an older model year, so is unlikely to work. Turing (same model as mine), Dirac, and Magnus do not. Of the currently available communal PhET devices, only the Macbook Airs (Jordan, Curie) recognize the input from this setup. ![]() Headphone jack splitter: Offers great audio quality but is only recognized by a limited number of Macbook models. USB: While the USB adapter offers higher compatibility (is recognized by more macs), there is, as reported, a continuous repeated beeping noise in the background as a result of how the USB port is powering the mic. ![]()
