Using The Correct Aspect Ratio & Video Sizes


Videos for the web should have an aspect ratio of 16:9. Videos with an aspect ratio of 4:3 will produce black bars if uploaded to social media platforms.

For websites best size is 1280 x 720 pixels with a lower frame. Anything higher could mean the video will be slower to open on lower specification devices and low Internet connection speeds.

For Social Media platforms you can use 1920 x 1080 which is an aspect ratio of 16:9.

We can produce 4K videos with a resolution of 3840 x 2160 which is an aspect ratio of 16:9.

Videos for viewing on TV should have a minimum resolution of 1920 x 1080.

We can produce video with custom dimension if needed with a variety of frame rates.

The first example shows what happens when neither of these aspect ratios is used - black bars will be produced. The second example is correct.

Starting the second video while the first is playing will paused the first. To restart the first video click / tap it. It will resume play while automatically pausing the second video.
