Resize a Video
This lesson is part of Web Developer Tools · All levels
Summary
Resize the video pixel dimensions, for example from 1920 x 1080 to 1280 x 720. If the aspect ratio is not maintained, the image will appear flat or elongated. Reducing resolution reduces the file size and speeds up playback on weak devices, while increasing resolution does not add to the original detail. Choose the size that fits the video to be displayed.
Key points
- Resize changes width and height of the entire video frame
- Keep aspect ratio so that the image is not distorted
- Decreasing resolution reduces detail but saves space and process power
- Upscaling only magnifies pixels, not creates new details.
- Video 1280 x 720 is known as 720p, whereas 1920 x 1080 is 1080p
