![]() ![]() Select Soundflower as your main audio output in your sound system preferences so that all sound output from your computer will go to soundflower. Download Sound flower from here and install it.Ģ. This program is called Soundflower, and here is how to use sound flower with iShowU HD to capture the output from an application such as keynote.ġ. To capture the audio from a program such as QuickTime, you need an extra program to use with iShowU HD. How to capture a Keynote presentation to a Quicktime movie (I assume you could do this with PowerPoint as well) The instructions for IShowU on the Audacity wiki say: 'If you need to hear what you are recording (which will usually be the case), you need to set up a 'Multi-Output Device' in 'Audio MIDI Setup'. Check the boxes for Built-in Output & iShowU Audio Capture in the 'Use' column. Click the '+' button at the bottom left of the window. You can buy this product with payment of 24 only whereas the standard plus advanced package is priced at 58 only. A way round this is to capture the output from keynote with iShowU HD and then save it as a QuickTime movie. I am considering installing IShowU Audio Capture, prior to upgrading from High Sierra to Mojave, but I am confused about multi-output devices. Install iShowU Audio Capture (link in checklist) like you installed Soundflower. iShowU Instant: This is a advanced real time screen recorder tool with lots of easy to access features, impressive presets, super fast type of capture engine, timers, audio filters, time lapse support and retina support abilities. For those of you who have tried to do this from within Keynote using the ‘export movie’ command you will know that when you export a keynote presentation the timing can be different from when you play it live, so if you have lots of transitions sequenced to a soundtrack, and you try to export from keynote, it can get out of sync. One way that it can be quite useful is that it can convert a keynote presentation to a QuickTime movie. I like iSHowU HD because it captures from Keynote, it captures movies from Apple’s DVD player, it captures sound as well as audio, you can set it to capture the full screen or just a part of it or a window, and it’s only $29. You may want to try them both out – they have a free demo period. ![]() I trialled out a few including Snapzpro but ended up settling on iShowU HD as my favourite. There are a number of screen capture programs for the Macintosh, some of them are free, some of then you pay for. You can also use it to turn a keynote presentation into a Quicktime movie and avoid the sync problems of Keynote’s built in export movie command. It costs $29 and you can get it from here. "I get audio on mic/aux 2" doesn't tell anyone anything except you, without a logfile, because only you know what device you selected under mix/aux 2 in settings > audio.I’ve had a few people ask me how I did the screen casts for Dragon Dictate. It may help to keep track of things if you disable all captures in Settings > Audio and add audio sources directly to a scene, and after choosing a device assigned to that capture, rename the source with the name of the chosen device so you know where the audio is supposed to be coming from. The others either don't have proper permissions, or aren't specified properly. If only mic/aux shows motion in the mixer, then that's the only source that is working. ![]() Your monitoring device should not be the same as one of your captures, or else sources that have monitoring on will cause echo. (terminology on this screen has changed recently, so new versions say "monitor off" where it used to say "output only". Monitor means "send to the monitoring device as specified in Settings > Audio > Monitoring device In the Mixer, Output means "send to stream or recording" You can set the system sound in your mac settings to EqMac and then open EqMac and set that to your headphones (theres a drop down to select devices). The matrix allowing for multiple channels with each source assigned to one or more channels only applies to recording where you are allowed to have multiple discrete channels. Channel assignment in the mixer is only relevant to streaming insofar as your devices have to be assigned to the one channel chosen for stream output or else the stream won't get that device. ![]()
