How do I estimate the amount of storage my video file will use up on my ZenVideo account?

Both weekly upload quota and total storage usage are determined by the size of the original source file at the time of upload. For example, a 200MB source file will use 200MB of the weekly upload quota or total storage limit. Plans that are measured by video usage are not impacted by video file size.

We understand you may want to try to calculate your video’s file size before exporting or compressing it. To get an almost accurate calculation of the video file size, it can be approximately determined by the bitrate rather than just the video resolution.

Bitrate is the most important factor in determining a video file size. Technically speaking, you can have a 4K video with a lower bitrate than a 720p video. However, in this instance, the 4K video quality would appear poor but take less space when compared to a 720p video. If your video contains audio, that track has its own bitrate as well.

Here is a chart for your reference:

The above table is for heuristic estimation and references only. There are a lot of other factors that influence the actual video file size such as compression ratio, variable bitrate, and color depth.

Video length alone isn’t a reliable determinant of how many GB it’ll use up. It can be impacted by:

• The quality of the footage.
• Whether the footage files have supplementary metadata files attached to them.
• The amount and quality of audio tracks in the editing timeline prior to export as a singular file.
• The size of a video file itself is largely impacted by how it’s being edited and exported. Each video editing software has a myriad of different export settings, all of which have complex impacts on the quality, size, and playback speed of the final file that is ultimately exported.
