Background
Why the limit bites, and what to do about it
- MB vs MiB, and why your 25MB file is not 25MB25MB means either 25,000,000 or 26,214,400 bytes depending on who is counting, and almost nobody says which. Here is how to be right either way.
- Why is my video file so big?A 30-second clip can be 4MB or 400MB. The difference is bitrate, resolution, frame rate and length — and only one of them is worth changing first.
