Note 2: Best Video Settings to Reduce Video File Size without Losing Quality
The size of a video file involves various video audio parameters. To help users to further shrink video file size with the editing functions provided by the video size reducer above, you are also suggested to check the simple guide on the factors that affect the file size and select the best video settings to compress video size without quality loss.
1. Resolution. Resolution refers to the number of pixels in an image. Currently, there are standard video (SD) 720 X 480 pixels and HD video 1,920 X 1,080, 4k UHD 4096 x 2160 and 8K FUHD 7680 X 4320 pixels. Generally, the higher the resolution is, the larger the file size will be. In other words, the downloaded 4k movie videos, or 4K clips recorded by camera or iPhone 6s may require file size reduction.

2.Frame rate. To reduce video file size without losing quality, frame rate is also a factor to concern. The higher number of frames will bring smoother motion effect. This means that video in 60fps will result in higher video quality compared with video in 24fps. However, 60fps is not as common as 24fps, and this is because the more frames in a video will significantly increase the file size.
3. Sampling rate. sampling rate is the number of samples of audio carried per second. Simply put, the higher sampling rate will result in higher audio quality. However, the higher quality means more samples are required, which will increase the file size. Therefore, the higher the sampling rate is, the larger the file size will be.
