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 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.
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: Click the “Convert” button; it will convert AVI/WMV/AVCHD/VOB/MOD/FLV/XviD to Apple TV H.264 MP4 on Mac immediately.
Once the conversion is done, you will be able to get the output files effortlessly.
