What is video coding? Explain how to generate video distribution and basic knowledge files. Part 2
What are the four points that must be checked before coding work?
Although the size of the video file becomes clearer when the encoding process is done, there are some things to consider, such as the quality of the video image becomes lower. From here, I will explain 5 points to be taken into account before coding work.
1. Convert to a compatible file format
The appropriate file format change depending on the purpose of use of the video. Generally, MP4 and FLV versatile are suitable for creating videos for distribution of videos.
If you already have a video distribution service you are considering using, we recommend that you check what file format is recommended.
2. Terminate coding rarely
If the encoding process is done, the quality of picture and sound quality will deteriorate as the amount of data becomes clearer, it will be impossible to restore the original quality. With experience, you can understand what bit rate and resolution should be used for conversion to get quality picture and sound appropriate.
If you are a beginner, you can leave the original data separately as a countermeasure, so even if a video is not code, you can start again, so you can be sure.
Bit rate represents the amount of data that can be sent and received per second. The higher the bit rate, the better the picture quality and sound. However, the higher the bit rate, the larger the file size, so we recommend changing the bit rate according to whether you want to encode the video must have a high image quality.
Resolution: shows the number of pixels called pixels contained in the video frame and is usually expressed as the number of horizontal pixels x vertical.
Example. 4K: 2160p (3840 x 2160) HD: 1080p (1,920 x 1,080), HD 720p (1,280 x 720), etc. The
the file size increases as you increase the resolution, which is adequate considering that. We recommend changing the resolution.
3. Note that coding time-consuming.
The time it takes to encode depends on many factors. Encoding time will vary with the frame rate, resolution, effects used for video, the encoder used and the use of encryption software, such as CPU performance computer.
For video files that have a time and a fixed delivery period, it is a good idea to codify enough time to prepare.
4. Do not lay too time video.
The longer the video is, the greater the data of the video file, which can affect encoding time. If possible, divide the video that is too long in two or cut unnecessary scenes for the video time is not too long.
If you try to encode a long video, it will be a heavy burden depending on the specifications of your PC, and there is the possibility that the work is not complete.
It is important to codify according to the purpose of the video.
Coding work is needed to create and distribute video with ease.
If the frame rate are emphasized, the resolution of the image quality, bit rate, etc., the size of the file will be huge, which will be a burden on both the side of the poster as that of the viewer, and the viewer can not play the video. comfortably and will go halfway. It is possible that you do.
However, the video encode, you can convert a video with quality picture and sound suitable.
This is a must for anyone who wants to make a video for training of the company or an open campus. We crastream recommend a platform video distribution system based on the cloud provided by us.
Crastream is a platform video distribution system high performance for limited objectives, members and employees. Thanks to high security, you can edit and post videos with ease without worrying about filtering external information to the outside. You can request materials for free, so do not hesitate to contact us if you are interested.
