Split plan for a 2 GB limit

By the Potok teamUpdated ~1 min read

The split plan for a 2 GB limit tells into how many parts a long recording must be cut so that every file stays under 2 GB. 100 hours at 256 kbps is 11.52 GB, so the recording needs 6 parts to keep every file under 2 GB.

Facts that matter here

  • Formula: parts = ceil(hours × 3600 × kbps × 1000 ÷ 8 ÷ 2,000,000,000), applied to the numbers in the table below.
  • Assumption: the bitrate is constant, 1 GB is 1,000,000,000 bytes, and the number of parts is rounded up.
  • Cut at pauses between speakers, so that no sentence is split across two files.
  • Every number in the table follows from the formula above; none was measured on a real recording.

How to use the result

Take your own numbers, put them where the table has its example values and repeat the calculation by hand. Write down the result with its unit, so that nobody has to guess later whether it was minutes, megabytes or characters.

Frequently asked questions

How does the split plan for a 2 GB limit work?

It applies one rule: parts = ceil(hours × 3600 × kbps × 1000 ÷ 8 ÷ 2,000,000,000). 100 hours at 256 kbps is 11.52 GB, so the recording needs 6 parts to keep every file under 2 GB.

What does the split plan for a 2 GB limit assume?

It assumes that the bitrate is constant, 1 GB is 1,000,000,000 bytes, and the number of parts is rounded up. If your case differs, repeat the calculation by the same rule with your own numbers.

What does the table of the split plan for a 2 GB limit show?

It shows: Hours, Bitrate (kbps), Total size (GB), Parts under 2 GB. Values: 10 | 320 | 1.44 | 1; 24 | 128 | 1.38 | 1; 10 | 1411.2 | 6.35 | 4; 100 | 256 | 11.52 | 6.

Where do the definitions behind the split plan for a 2 GB limit come from?

Units, formats and rules are described in the sources listed at the bottom of this page. The numbers in the table are calculated here by the formula above and are not copied from those sources.

How do I avoid a mistake with the split plan for a 2 GB limit?

Cut at pauses between speakers, so that no sentence is split across two files. Use it when a recording is longer than one upload allows.
