Hey Folks,
I'm quickly falling head over heels for TwinMotion but I have run into a hiccup recently. I've taken a 15 second video and exported it but the results were kind of odd. It's warbly and stuttering and I'm wondering if there's a setting or something that I'm missing? Any assistance would be appreciated. Thanks!
HI ,
It looks like this is a video that is using Path Tracer for rendering. This behavior is actually the result of the denoiser trying to correct the noise generated from the Path Tracer render. Unfortunately, the denoiser isn't as effective with temporal noise in videos as it is with static images. This is something the team is working on improving in future updates to make the denoiser much better with videos.
For now, there are a few ways to try and get a much better-looking result. There are third party tools, such as Adobe Premiere, Neat Denoiser, and DaVinci Resolve that have fairly good denoisers that you can use. If you disable the denoiser for your exported video, you can then apply the denoiser in one of these third-party tools.
Inside Twinmotion, increasing the number of samples per pixel for Path Tracer can also decrease noise in videos, although this will also increase render times proportionally.
You may also find that exporting your video as a series of images (setting the format to .png, .jpeg, or .exr instead of .mp4) then stitching the frames together into a video might also give better results.

Hey Raghib,
Thank you for responding to me. I've tried exporting this video and stitching it back together as PNG files. That unfortunately produced the same results, same with increasing samples per pixel.
So as these options yield the same issue, I need to export videos with the denoiser tool turned off and then need to use a 3rd party to fix the rendering issue here. I'm curious if you have any suggestions for any online, low cost or possibly free software for denoising? Making videos with your software was one of the advertising tools that got me interested in the software but knowing that I now have to pay, and learn how to use, a 3rd party program to fix the more or less un-usable videos from Twinmotion seems a little peculiar.
I know you have mentioned that the team is working to improve this issue, do you know if that's something that will be updated in the near future? I'm just not too keen to spend time learning new software, and likely paying for it, when Twin might have solved the issue in the near future.
Thank you for your time. The still image renders are incredible so I'm happy with this improvement, but would love to be able to generate short videos that look as nice as the still images in a simple process. Have a great day!
Hi,
Regarding the improvements, the team is targeting some improvements to arrive when we update Twinmotion to utilize Unreal Engine 5.1 (currently expected around the end of Q1, though this may be subject to change), however these may not entirely eliminate the problem, and it may be some time before the denoiser works well enough that third party tools would be entirely unnecessary.
Right now, the third party denoisers that seem to offer the best results would be the Neat Denoiser, which is a plugin for several video editing software suites that includes a free demo version you can try. Davinci Resolve and Adobe Premiere also offer denoisers that work fairly well.
I hope that's of some help.
Best,
Raghib
