Your program is still in beta version since 2012. Still has a 32 bit system. It’s already the summer of 2022, and the program has not been updated since 2015.

The essence of the petition is that the Valve company would pay attention to the creative community and take the following steps:

1 - Make the transition Source Filmmaker to a 64-bit system (The program does not accept more than 4 gigabytes)

2 - Transfer the program to the latest version of the source engine

3 - Make support for all languages

The program had and has great potential, but you decided to abandon it.

We understand that you are busy developing the Source 2 engine, but please don't forget about those who are still working on the Source 1 engine.
We hope for your understanding and solidarity.
