What is the standard bitrate for smartphone videos? Part 3
Estimated audio bit rate
In the case of audio bit rate, “128 kbps” is basically a guide.
Generally, for lossy codecs like MP3, AAC, WMA, AC3, Vorbis, a voice bit rate of around 128 kbps is sufficient. On the other hand, if the video is geared towards sound quality, it should be around “192-320kbps”.
Three Points to Consider When Considering the Bitrate of Smartphone Videos
There are a few things to keep in mind when considering the bitrate of your smartphone video.
When creating a video, you should use the appropriate bitrate for factors like size, but when considering bitrate, you need to keep three points in mind.
Here, we will introduce three points to keep in mind when considering the bitrate of smartphone videos, so why not refer to what kind of points to keep in mind?
Bit rate notes 1: The numbers are just a guide.
The proper bitrate for smartphone videos is just a guide.
The bitrate of a video involves multiple factors, not just the size of the image. For example, if you want to save a video with a lot of movement in high quality and a video with little movement that you want to save in medium quality, the appropriate bit rate will be different even if the image size is the same.
So, consider the bitrate you need as a guide only.
Bit rate note 2: consider the resolution according to your purpose
Let’s decide the optimal resolution according to the purpose of the smartphone video.
Even if you call it a smartphone video, it does not mean that a video with almost no motion and a video with high motion should have the same resolution. It is important to select the one that suits your purpose, such as high resolution for videos showing precise movements and low resolution for videos with little movement.
Therefore, when considering the resolution of a video, consider what the video is about.
For seminar videos
Since the seminar video is almost motionless, no high resolution is required.
The seminars and training videos aren’t particularly poignant videos, so lower resolutions won’t be a problem. For example, there is not a big difference between a low image quality of about 300 kbps and a high image quality of about 1500 Kbps, so it is recommended to make a light and low quality video.
For promotional videos
For promotional videos, it is a good idea to have a certain resolution.
It is not attractive that the resolution is low and that the video does not look beautiful in the video for internal promotion. However, it depends on the content of the video itself, so if you are not sure about the resolution, it is recommended to prepare a higher resolution and a slightly lower resolution and compare them.
For sports videos
High resolution is best for sports videos.
The bit rate has the characteristic that it is required since the difference with the previous frame is greater, and it is necessary to set it higher for videos with a lot of movement.
Therefore, if the resolution of the sports video is low, the outline will be broken and the color will fade, resulting in a stressful video.
Bit rate note 3: consider file size
The higher the bit rate, the larger the file size.
Of course, it depends on the content of the video, but as the bitrate increases, so does the file size, so this needs to be taken into account.
