Video2commons own upload

If all these 3 conditions are true:

1. your device produces a file that contains a timestamp of the format 20260630 123456789,
2. that timestamp represents the starting time of the recording,
3. you use a filename 20260630 123456... for your own work via com:v2c,

using the following code block for the "file description page" will automatically set date to be {{other date|from|2026-06-30 12:34:56}}. The numbers 01, 04, 05, 06... indicate the positions of the filename string from left to right. Adjust the numbers if the timestamp is in a different position in your chosen filename format.

Adjust everything according to your needs.
