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.
Today is Sep 18, 2025 and Twinmotion 2023.2.3 is still exporting an empty file when exporting MP3 video. Exporting video as PNG works, but it’s a hassle to compile 1000s of images into a video.
This TM build was exporting MP3 videos BEFORE I upgraded from Windows 10 to Windows 11 Pro.
@MC_Jut or any other nice people at Twinmotion Support, can you advise a fix for this bug?
Thank you!!!
I used https://obsproject.com/ to screencapture the video as it played in TM. The resolution is not as good as a native TM video export, but that’s my workaround.
Oktober 2025 and I have the same problem. I have Windows 11 and im using Twinmotion 23 for revit 24. Is there any solution already?
