Hardware

There are multiple capture device options to choose from. Here is a list of currently known choices:

• Elgato Video Capture
• Intensity by Black Magic Design: Intensity Pro (internal card for Mac Pro), Shuttle (USB 3.0 version is Windows only, you need Thunderbolt), and Extreme
• EasyCAP
• Dazzle for Mac (this seems to be really hard to find.)
• Dazzle DVC 100 (Windows only, but guides on YouTube explain how it can be used on OS X.)
• Hauppauge HDPVR
• AVerCapture M
• Game Capture HD
• Game Capture HD 2
• Elgato Game Capture HD

Elgato Video Capture

(To do: Need Elgato users to explain details here.)

Intensity

Intensity users will likely capture their streams using Black Magic Media Express. This software comes with the Intensity, and supports QuickTime codecs. However, by default it will only offer uncompressed video for maximum quality recording. This is not optimal for disk space of performance, so it's a good idea to install the ProRes codecs (using unpkg if necessary to get to the individual codecs) in order to have more options. Quoth CMiller:

There are several variations of ProRes:

• ProRes 4444: Used primarily for 4K work or feature film finishing.

• ProRes 422 (HQ): High quality used for HD finishing. Same as 422 but with higher datarate.

• ProRes 422: Used for HD editing. Broadcast quality.

• ProRes 422 LT: 2/3 the datarate of 422. Used for proxy work mostly.

• ProRes 422 (proxy) - 1/3 the datarate of 422. Used for proxy work.

Capturing in 422 (HQ) and 422 both work wonderfully for 720p capture.

EasyCAP

There are 3 known applications that will capture video from this device: Norichan, EasyCapViewer, and VideoGlide. Norichan will only capture from the Stk1160 model (go to System Information -> USB. It should be called "USB 2.0 Video Capture Controller" and the manufacturer is Syntek Semiconducter). EasyCapViewer supports multiple models (check its site to see which ones), but its recording features are not on par with Norichan's (so no SDA submissions; needs confirmation). VideoGlide also supports specific models only, and is supposedly harder to setup properly (users with more knowledge can elaborate on this).

Software

Refer to the Mac Recording and Streaming page for more on software and how to use them.

Capturing

The software used for capturing can vary with the capture hardware used. See above.

Editing

iMovie is a free and preinstalled option. From here it's pretty easy; just import whatever you want, then edit your clips so they start and end when you want them to.

(TODO: verify the following two paragraphs. I suspect a workflow of iMovie to Handbrake is more useful. Verify this.)

Once you have your clips ready to go, export them one at a time. If you want to, you can end your capturing adventures here by exporting to MPEG-4, the highest quality Internet-friendly format offered with QuickTime (choose "Expert Settings" when you go to Share your movie). Make sure that "Hinting" is turned off. Feel free to play around with the bit rates to find a level of quality you feel is satisfactory.

If you want to create a 60 FPS file it is recommended that you use ScreenFlow, which offers low CPU, lossless screen recording, post-productions features, and multiple encoding choices including x264.

Streaming while Recording

Refer to Mac Recording and Streaming for a list of software that can accomplish this.
