Whenever I upload a video to YouTube, it deteriorates.
When you upload a video to YouTube, it will be automatically encoded. “Encoding” is the compression and conversion of video data, which changes it to a format that can be played on YouTube.
Depending on the size of the video, “compress” means that the uploaded video will be of lower quality than the original video.
Actually, even at the video editing stage, it will be encoded last, so there is a chance that it will deteriorate twice.
In particular, action games with intense movement tend to be easy to understand and the visuals tend to be crude.
It is recommended to record the highest quality video possible at the recording stage so that it will be fine if the image quality deteriorates a little later.
This blog introduces how to record game video on your smartphone and also introduces how to record in the highest quality possible. Try to reference.
What kind of video is “high image quality”?
There are three essential elements when it comes to “high quality” video: “resolution”, “frame rate” and “bit rate”. I think it is a value that is often seen when editing videos.
The details will be presented later, but it can be said that the higher the “resolution” and the “frame rate”, the higher the “bit rate” and the higher the image quality.

1. What is resolution?
It is a word that expresses the number of pixels (pixels) in the vertical and horizontal directions of a video. It is something like “1920 x 1080” or “720P” that you see often. HD, Full HD, 4K, etc. They are also common names that refer to resolution.
If the screen resolution is high, it will be expressed in many pixels, and it will be a clear and detailed video, that is, of high quality.

I think there are many opportunities to see the resolution when recording a video or when exporting after editing a video.
When you want to get a rough idea of the quality of your own recorded or edited videos, it’s a good idea to focus on resolution.
YouTube resolution (16: 9)
We recommend 1080p and 720p, but YouTube supports other resolutions as well. Basically let’s make a video that will be one of these.
resolution Known as comments
3840 x 2160 (2160p) 4K Transcendental beauty! Conventional TV picture quality
2560 x 1440 (1440p) WQHD Very beautiful! This is also the picture quality for TV.
1920 x 1080 (1080p) Full HD, Full High Definition, 2K It’s beautiful enough! The highest quality of videos recorded on smartphones.
1280 x 720 (720p) HD, high definition Everything is beautiful! If you record it with a small smartphone, this is what it is all about
854 x 480 (480p) full-width VGA It’s as beautiful as a DVD. The videos are tolerable, but each time they are more beautiful
Youtube Video recommends the aspect ratio of 16: 9. If you use a video with a different aspect ratio than this, a black frame will be displayed vertically and horizontally, so be careful.
2. What is the frame rate?
Frame rate is the number of still images (frames) displayed in a video per second. . The unit is “FPS (Frames Per Second)”. Basically I think it is often written in lower case (fps).
Please note that it is different from the “FPS (First Person Shooter)” shooting game genre! (It’s more complicated because conversations like “I want a monitor to do FPS at 120 fps” are also possible).
A movie is a series of still images. I think it is easy to understand if you imagine a flip book.

The smaller the number of still images displayed per second, the more inconspicuous the video will appear, and the higher the number, the more continuous it will appear. This is the difference in frame rate.
In other words, the higher the frame rate (= the higher the number of still images), the smoother the video will be. .
Frame rate is a numeric value that can be set at encoding time, and I think 30fps or 60fps is common.
If you also increase the fps, you will increase the file size of the video. If you want to stick to smoothness, like action videos, judge at 60fps, around 30fps otherwise.
