Why can't I send long videos in WhatsApp?

iPhone
If you choose to send an existing video, it is limited to 16 Megabytes. On most phones, this will equal about 90 seconds to three minutes of video. If you choose an existing video that is larger than 16 MB, then you will have the option to trim the length of the video before sending it. If you are trying to send a video that you have previously received, please use the Forward button to forward the video via WhatsApp. To forward a video:
  1. Open the chat containing the video.
  2. Tap and hold the video.
  3. Tap Forward.
  4. Tap the forward button in the bottom left corner and choose your recipient(s).
