Tips to Resizing a Video

Keevi provides plenty of file formats to export your final video. Consider the effect of the file type you choose on video quality and size.

  • The MP4 file type is the best for maintaining video quality while keeping the file size small.
  • A MOV file type provides a video format of high quality while also being significantly large.
  • WMV is a small file size with better compression than MP4. But it’s incompatible with Apple devices.
  • An FLV file is easy to download and relatively small. But it's incompatible with most mobile devices.
  • An AVI file tends to be of a very large size. It might not be a great choice when trying to save on space.
  • It’s best to choose the resolution based on your type of project. But keep in mind a larger resolution equals a larger file size. A 720p video, for instance, will have a smaller file size than a 1080p video.
  • If you are recording a video or using our screen recorder, minimize movements and transitions to keep your file size small.
  • Aspect ratio refers to the relationship between the height and the width of the video. Get the right aspect ratio for your social media videos. It is vital in preventing inconsistencies as the videos display on your audience’s devices. 
  • As you create your videos, always keep important features, such as text and image overlays away from the edges. This will make it easier to crop your videos without losing important information.
