This fixes

  • An old clip will not play on a phone or browser.
  • The file came from an old camera, phone, or archive.
  • You need a more durable MP4 copy.

How to handle it

  1. Identify the old source format.
  2. Convert to MP4 for modern compatibility.
  3. Play the MP4 and keep the archive original.

Before you submit

  • Expect old videos to keep their original resolution limits.
  • Check audio sync after conversion.
  • Keep the original if the archive matters.

Choose the right output

Check 1

Use MP4 when old clips need to play on phones, browsers, or upload forms.

Check 2

Keep the legacy source file if the archive has personal, legal, or historical value.

Check 3

Check audio sync and resolution after conversion because old files vary widely.
