Part 1. What Affects Video File Size

Before reducing the video size, it is important to know the factors that define whether the video is larger or small. There are many variables on which the size of the video depends on resolution, bitrate, video length, frame rate, encoding, and more. Some of the major ones are discussed below.

1. Resolution: It is measured by the pixels of the video and one of the main file size deciding factor. The higher the resolution, the higher will be the file size, and the better will be the quality.

2. Bitrate: A bitrate is generally measured in Mpbs and kbps, and it defines the measurement of the information that is transmitted in a second. If the bitrate is higher, more information needs to be transmitted, and thus the file size will be larger. Whether the bitrate is constant or variable also plays a major role in deciding the file size.

3. Video length: A longer video will have a larger size in comparison to a short video.

4. Frame Rate: Reducing the frame rate reduces the file size proportionally. Generally, a video is recorded in 30fps (frames per second) and so if the frame rate is reduced to half, the file size will also be reduced. The size also depends on the progressive or interlaced frames.

Additionally, audio sample rate, rendering quality, buffer size, and other similar factors also play a role in deciding the video file size.
