Why You Need to Compress Videos?
Video compression reduces file size, making videos easier to store, share, and stream. Here are some situations where you might want to compress your video:
- Sharing video files: There are limits on the size of files that can be shared via email or some instant messaging apps. Compressing videos makes it easier to share files.
- Storing files: By reducing video size, you can save storage space on your computer, phone, or cloud storage like Google Drive.
- Streaming videos: Compressing videos makes them easier to share on streaming platforms and reduces buffering. Without compression, some online platforms and devices cannot handle large video files.
- Editing videos: Editing high-resolution videos can be resource-intensive. Compressing videos can make the editing process smoother.
Factors that Affect Video Size
Many factors affect the size of video files, among which the most influential are video length, frame rate, resolution, and bitrate. In addition, the audio bitrate also affects the size of the video. Below, I will explain these factors one by one:
- Resolution: A video’s resolution determines the number of pixels in each frame. A higher resolution results in a larger file size.
- Frame Rate: Frames represent the number of individual static images displayed on the screen per second. The higher the frame rate, the smoother the video and the larger the file size.
- Bitrate: Bitrate refers to the amount of data used to encode the video per unit time. A higher bitrate results in better video quality and a larger file size.
- Length: The longer the video, the more data it contains and the larger the file size.
- Audio Bitrate: The audio bitrate indicates the amount of data contained in one second of audio. A higher audio bitrate means better sound quality, but a larger video file size.
