Trimming videos with MPEG StreamClip

Note: MPEG StreamClip no longer appears to be actively maintained.  In addition, the Windows version depends on QuickTime, which is no longer supported, and may have security vulnerabilities. Lossless Cut is another alternative under active development that may be worth trying.

MPEG StreamClip is a handy piece of software that can be used to trim videos quickly without needing to re-encode them.

You can download the free software for macOS or Windows here.
