How do I achieve good video quality?

There are many factors that can affect the quality of the video during your live shopping event. In this article, we'll cover optimal essentials.

As you check for an adequate internet connection, make sure you're choosing the right video quality for your event as well, which includes choosing the right video resolution, frame rate, and bandwidth

1. Choosing the right video resolution

Video resolution is the number of pixels contained in a single video frame. In other words, it determines the amount of detail in the video, or how "clear" it will appear in the final rendering. It is typically measured by an aspect ratio, which is the measurement of a video's width by height. In this case, the unit of measurement is pixels.

Here are some commonly used video resolutions:

Today, most devices can deliver FullHD resolution at least, from low-end LCD TV to less-than-100$ Android Smartphones.

When it comes to social networks, however, most of them deliver HD video quality but not all can go beyond that.

So, while the latest high-end smartphones (from Apple (iPhone 11 Pro) or Samsung (Galaxy S10) onwards) as well as the latest desktops, laptops and LED TVs support UltraHD resolution, they won't show the whole resolution during a social broadcast. Most of the time, it will be a 2.5K resolution, which is just above FullHD.  

2. Choosing the right video frame rate

Video frame rate is the number of frames that you will find in a second of video. The higher the frame rate, the smoother the video will look.

The video standard is 30 images per seconds (30fps), although 60fps is becoming more frequent, especially for FullHD and UltraHD, to avoid quality downgrades.

3. Choosing the right video bandwidth

Video bandwidth is the amount of information or data that can be transmitted per unit of time. The video bandwidth is a critical and logical parameter. The more "space" you have, the more data you can transfer, and the more detailed and precise your video will be. 

As you can imagine, video frame rate and bandwidth are directly correlated. The higher the video frame rate, the more video bandwidth you will need. 

Despite recent progress in video compression (such as MPEG4/H.264 and recently HEVC/H.265), you need sufficient bandwidth to stream your content. This is a critical consideration when you upload your video content to Livescale. The "bigger" your video is, the more compression your video will go through. But rest assured! We generate multiple streams of different resolution and bitrate for you, so that your viewers can enjoy seamless video no matter what happens.
