Photoshop: Is there a way to make a video animation longer than 500 frames?

Question

Animation

I know how to make an animation longer than 500 frames using frame-by-frame animation (solutions are easily available on the Internet), but this one doesn’t suit me at all, and despite the fact that I managed to connect 2 video sequences together, when creating an animation, it still has a limit of 500 frames .
Maybe there are similar programs, but more developed in this regard?
Help who thread, it is very necessary.
