We can tell from the formula that, for a raw video of a certain length, its size was determined by the frame rate, the resolution, and the bit depth. Video file size = Time (sec) x Frames per Second (fps) x Pixels per Frame (resolution) x Bit Depth

Factors That Determine Video File Size and Quality In the first place, to get a better understanding of how to reduce file size without losing quality, we should figure out what factors are affecting the size and quality of a video. What we can do is to minimize the quality loss while decreasing the file size. So when we want to release the storage or share a video via Instagram, Facebook, or Twitter, we have to compress it into a smaller size.īut here comes another headache - How to compress video files without losing quality? Actually, compression is a process to reduce data stored in the file, thus, unavoidably, causes quality loss. A 10-min 4K video shot by iPhone 11 takes up 3.9GB. But we all know it is at the cost of sacrificing much storage space. Select the “Start Encode” button (“Start” on a Mac) to finish the process.With the fast growth of 8K and UHD 4K DSLRs, drones, action cameras, and smartphones, it is not rocket science for average people to capture high-quality videos.Edit the file name and desired destination in the Save As area at the bottom of the screen.Once the video is open, you can select the “Very fast 720p30” under the Preset>General menu.If you are working on a Mac, the Open Source button will open the file selection menu where you can navigate and select the desired files.

If your refer, you can also select the “File” button, and find the desired video to add to you project.
