The Proper Way to Encode Video on a Mac
To ensure an optimal upload and playback experience, videos uploaded to Cast It & Cast It Talent from a Mac computer should be encoded in Quicktime as either .mov or .mp4 files only.
Files that do not meet our requirements may not play correctly on the site, so be sure to always encode video with the following general settings.
Quicktime
  • File Type: MOV or MPEG-4
  • Codec: Mpeg-4 video
  • Frame Rate: 24
  • Key Frames: Every 300
  • Data Rate: 768 Kbps
  • Video Size: 640 x 480 VGA
  • Audio Format: AAC
  • Audio Channels: Mono
  • Audio Rate: 32.000 KHz
  • Audio Target Bit Rate: 32
Note : The size of an individual video file should not exceed 50 megabytes. You can check the size of your video file by following these steps:
1) Find the file on your computer, then click the file to highlight it.
2) Go up to File, then click on Get Info.
3) When the info box appears, look under the Size heading.
If your file does exceed the 50-megabyte limit, you will need to shorten the clip or edit it into multiple parts before uploading.
Which program should I use to create and encode my video files?
There are many editing programs that can encode files to our recommended settings. Below are the step-by-step instructions for iMovie, which is the most commonly used editing program on Mac computers.
Make sure to check which version of these programs you have on your computer, and read the corresponding instructions for that version below.

      Note: we recommend that you capture each individual take for an actor’s audition separately. This will keep file sizes to a minimum. As a reminder, do not upload files larger than 50 MB.
