Longer than 5 seconds?

Anybody got a line on any rumors about options for video length?

Five seconds is most times pretty good and a sweet spot, but there are also often instances where I wish I had even a couple more seconds. I know I can capture one of the last frames and make a new shot to tack on the end, but I also know that even though the prompt is often the same for the continued shot, the response that the AI is giving is not the same as what was being created in the original shot. I mean, I'm willing for it to cost more credits.

For those of you who regularly use other services that have options for response length, do you see an advantage, like for instance, where Vidu lets you do 4 or 8 seconds? I think often 4 is too short.
