If you have any Apple device like iPad, iPhone, iPod touch, or Apple TV, you can make full use of them using AirPlay. You can use AirPlay to stream videos, music wirelessly from your iPhone, iPad, iPod touch, or iTunes on your computer, to your HDTV and speakers via Apple TV (2nd and 3rd generation), or to your AirPlay speakers or receivers, including AirPort Express. Here in this page, we will show you how to stream videos, music to Apple TV 3 via AirPlay on Mac.

PartⅠ: Make all your videos AirPlay-Compatible
In order to stream media files to HDTV via ATV 3 using Airplay successfully, you need to make all your video compatible with Airplay in advance. Here's how to convert your video collection to play over AirPlay with good video quality on Mac.

Required tool:
Brorsoft Video Converter for Mac

With the best Video Converter for Mac, you can convert/re-encode any video files like AVI, WMV, AVCHD, VOB, MOD, FLV, XviD, etc to the AirPlay friendly format on Mac effortlessly. Apple's specifications allow for both the MPEG4 and H.264 codecs, but H.264 is a better choice we find. Below is the step-by-step guide.

Step 1: Import AVI/WMV/AVCHD/VOB/MOD/FLV/XviD files to the recommended software.
Run Brorsoft Video Converter for Mac. Click the button “File” to add video files to it. If it is necessary, you can double click the each file to have a preview.

Step 2: Select H.264 MP4 as the best video format for AirPlay and set the output folder.
Click on the dropdown menu of “Format” and then move your pointer to “HD video > “H.264 HD Video (*.mp4)”. You can also choose the “Apple TV H.264 1280*720(*.mp4)” from the “Apple TV” sublist. By using this format, you can expect the best playback performance when airplay videos to your HDTV via ATV 3.

Step 3: Click “Settings” icon to adjust audio and video parameters.
Click the “Settings” icon and you can adjust codec, aspect ratio, bit rate, frame rate, sample rate and audio channel in the interface to optimize the output file quality. Then set the output folder by clicking “Browse” icon.
PS: Airplay doesn't do anything to resolution, because that would mean real-time re-encoding. It just sends the already-compressed file over the air. If it's 1080p to begin with it'll stay at 1080p on the ATV3. Thus, you can set the video size as 1920*1080, it should play that 1080p Airplay stream.

Step 4: Start converting AVI/WMV/AVCHD/VOB/MOD/FLV/XviD to the best Airplay supported format on Mac.
Click the “Convert” button; it will convert AVI/WMV/AVCHD/VOB/MOD/FLV/XviD to H.264 MP4 on Mac immediately. You can find the process in the “Conversion” interface. Once the conversion is done, you will be able to get the output files effortlessly.

PartⅡ: Stream videos, music to Apple TV 3 via AirPlay on Mac
