Video Export Creates an Empty File

Same problem, @MC_Jut please advise.

Is there a solution for this issue? I have Windows 11 pro. Hoping to export a video for a client asap

I have the same problem. were you able to find solution?

Spent the whole day trying to convince Twinmotion tu use my RTX 4090 insead of RTX 3090. FAILED! 12 hours wasted. I resign myself to letting him use the 3090, I make the video, but surprise, after the rendering I find myself with only an empty file. Honestly, this is not a product, it’s a joke!

THis is April of 2025 and I have the same problem…
I have Windows 11 Pro
Exporting model from Revit 2025 (and 2023, have tried both) using Datasmith.
Thave tried both Twinmotion 2023.3 and 2024.1.
Using GeForce RTX 3080.
Have exported video in the past. Now getting 0 byte mpeg exports.
Will attempt to do a rollback on my video driver.
Any help will be appreciated. Client has seen the video exports in the past and is waiting for current video walkthrough.
