Means your Nvidia driver is out of date. Update your Nvidia driver
Can i use MotionGen on Nvidia 2070 and similar?
Technically, yes, but do not expect a fast process. It can be up to 10x slower with 8GB of VRAM, and it will fall back on RAM.

That means the video format you are using is not acceptable, WebM. This is not an actual video it's some kind of image sequence. Please use a proper file format MP4, MOV, AVI. Some MP4s have another codec you can use HandBrake to convert them to standard mp4 format. https://handbrake.fr/
When i want to activate the license i got the error activation limit reach 1/1 ?
You already activated MotionGen on one PC and cannot transfer it to another PC, you can not see it on the same machine. This can only happen if a single license is tried to be activated on more than one PC. Note: the Ultimate version can be activated on up to 10 PC and it is prone to such issues.
How many times i can activate the license on same PC?
Unlimited times, you can remove and reactivate your license unlimited time as long as you activate it on the same machine.
If i change my windows can i reactive the MotionGen?
Yes, the MotionGen license is not use Windows or Blender fingerprint, and changing Windows will not have any effect on the license at all.
Can i transfer the license to another PC?
No, the license is tied to the hardware fingerprints and can not be transferred or activated on another PC.
Can i use MotionGen with multiple blender on same PC
Yes, you can use MotionGen with as many Blender versions as you want, as long as you use it on the same PC

Go to the MotionGen preferences and click on "Fix File is not a Zip file" then, after the process is finished, restart the engine and try again
