Video on Apple: File Requirements and Encoding

File requirements

What is the file size limit?

Video files must be under 10 GB.

👉 Learn how to stay within this limit:

What video format should I use?

Recommended:

  • Format: .mp4

  • Video codec: H.264

  • Audio codec: AAC

What resolution and quality should I use?

Recommended:

  • Resolution: 1080p (1920×1080)

  • Bitrate: 5–10 Mbps

  • Color: SDR (not HDR)

Can I upload a 4K video?

Yes, but it’s not recommended. 4K significantly increases file size with limited benefit for most viewers.

Is vertical video supported?

Yes, but it may appear with padding. For best results, use landscape (16:9).

Uploading & encoding

How long does it take to upload and process a video?

This depends on:

  • Your internet upload speed

  • File size

  • Processing time

Do I need to stay on the page while uploading?

Yes. You need to stay on the page until both:

  • Upload is complete

  • Encoding has finished

If you leave early, the video will not process correctly.

What is encoding?

Encoding prepares your video for playback and distribution.

This includes:

  • Converting formats

  • Optimising for streaming

  • Syncing audio and video

  • Preparing distribution
