Conclusion In this article, we introduced how to set up an online class using learningBOX and the video sharing site Vimeo. By using Vimeo, you can not only distinguish between public and private videos (password-protected or open only to those you wish), but you can also set detailed privacy settings for each video. The domain name of the video can also be specified, which is useful for making videos available only on the company's own website or on closed member sites.

This is Kidaoka, Marketing Manager. In this article, we will explain the relationship between video file size and image quality, and show you how to set a smaller video file size. When uploading video materials on learningBOX, the file size of the video file exceeds the capacity of the file, so you cannot register the video file you have taken and have to re-take it again! Please refer to this article to find out how to compress your video files.

Since many images are stored in a single video file, the file size naturally becomes larger. The size (capacity) of a video depends on three main factors: bit rate, resolution, and codec. Let's take a closer look at them one by one. Bit Rate The bit rate is the amount of data that can be sent and received in one second. The unit is bps (Bit Per Second), which indicates how many bits can be transmitted in one second (Per Second). In simple terms, it is a unit that expresses "how much data can be transferred. The higher the bit rate number, the higher the image quality and the larger the video file size. Resolution Resolution is a numerical value that expresses the density of pixels in a video. In digital video, it is expressed as "a collection of very small colored dots (pixels). The unit of "dpi" or "ppi" is used. The higher the resolution, the higher the density of dots, and the smaller the resolution, the smaller the video capacity. Codec A codec is a device or software that performs the encoding (compression) and decoding (playback) of data. Handling large-sized videos uncompressed requires large memory, hard disks, etc., or compressing the video capacity to reduce its size. Calculation Method for Video Files The data capacity of a video file is calculated as follows ▶Here is the calculation formula Bit rate of video × Length (seconds) ÷ 8 (convert bits to bytes) Since the amount of data per second is the bit rate, multiply the time and convert it to bytes to find the video file size. Exercise For a 10-minute video at 2.5 Mbps, what is the file size? →2.5Mbps × 600 (seconds) ÷ 8 = 187.5MB (megabytes) ▼Here is a quick table on video capacity. Please use it as a guide when uploading your video. The actual capacity may go up or down slightly when audio is added, but this will give you a rough idea of the capacity of your video. Here is how to compress your video using FFMPEG FFMPEG is a command line tool to convert audio or video formats. In this article, we will show you how you can easily compress videos using this tool. (Works on Windows 7 or later) If you have any problems such as audio skipping or overlapping when uploading videos using the newer version, please use the older version here.

STEP②: Extract the downloaded zip file. Compress the video using the unzipped Encoder STEP ③: Open the extracted zip file and click on Encoder.exe. STEP④: Select the quality of the video if necessary. STEP⑤：Drag and drop the video you wish to compress. STEP⑥: Encoding of the video will begin. Please wait for a while until the encoding is finished. When encoding is complete, the video will be compressed and saved in a smaller size. *Please note that some images, audio, and video files may not be reduced in size even if the video is compressed. Conclusion In this article, we explained the relationship between video file size and image quality, and introduced how to set the size of video files smaller. Shooting and editing videos is a really time-consuming process. If you are worried about uploading your videos due to their large size, please refer to this article to learn how to compress your video files! LearningBOX has plans that can handle large videos. By using the standard plan, the file size limit per video is relaxed, as well as the total amount of content that can be uploaded. For more information on video capacity per plan, please see About Video Capacity. Thank you for your patience with this paper. We also recommend this article!

Regarding the size of video files when creating e-learning materials I am Nagai🎮 of Quality Control, suffering from a cold that is not completely gone. This time, I would like to share with you a question that we have received many inquiries from our customers: "When uploading e-learning materials, how long is a video file and how much space does it take? This article is an explanation and a small piece of information in response to this question. Thank you for your understanding and cooperation. Click here for Table of Contents 1. what is a video file 2. how to calculate a video file 3. how to upload a video file to learningBOX 4. summary What is a video file? A video file uses the same principle as a flip book to show a series of still images one after the other to make the picture appear to be moving. A single video file contains a number of image files, and the file size naturally becomes large. The size (capacity) of a video file depends mainly on the numerical values of factors such as bit rate, resolution, codec, etc. Let's take a look at each of these factors in detail. Let's take a look at them one by one in detail. Relationship between file size and image quality Bit rate This is a unit of rate at which data is transferred. In simple terms, it is a unit that expresses "how much data can be transferred. The higher the bit rate number, the higher the image quality and the larger the video file size. Resolution Resolution is a numerical value that expresses the density of pixels in a video. In digital video, it is expressed as "a collection of very small colored dots (pixels). The unit of "dpi" or "ppi" is used. The higher the resolution, the higher the density of dots, and the smaller the resolution, the smaller the video capacity. Codec A codec is a device or software that performs the encoding (compression) and decoding (playback) of data. Handling large-sized videos uncompressed requires large memory, hard disks, etc., or compressing the video capacity to reduce its size. POINT Generally, to improve video quality, it is necessary to increase the resolution (fineness) of the video, and to increase the resolution of the video, it is necessary to increase the file size of the video. In particular, the size of the bit rate, which represents the file size per second of video, will greatly affect the quality of the image. However, if the bit rate is too large, the performance of the communication line and terminal will be greatly burdened when the video is transmitted over the Internet, causing the video to not play smoothly. Video File Calculation Method You can calculate how much the file size of a video file will be. The data capacity is calculated as follows. ▷Here is the calculation formula Video bit rate x length (seconds) ÷ 8 (convert bits to bytes) Since the amount of data per second is the bit rate, multiplying the time and converting it to bytes will give you the video file size. Exercise For a 10-minute video at 2.5 Mbps, what is the file size? →2.5Mbps × 600 (seconds) ÷ 8 = 187.5MB (megabytes) ▼Here is a quick table on video capacity. Please use it as a guide when uploading your video. The actual capacity may go up or down slightly when audio is added, but this will give you a rough idea of the capacity of your video. How to upload a video file to learningBOX When uploading a video file, the size of the file may vary depending on the settings used at the time of shooting and the performance of the equipment used at the time of shooting.
