Factorio: Space Age - Trailer at 60fps uses 30fps footage with frame duplication, causing motion sickness

This is not a game bug, but I couldn't find a more appropriate place to report it.

The 60fps version of the "Factorio: Space Age - Trailer" is incorrectly encoded, making it painful to watch. It feels twitchy and causes motion sickness.

The trailer utilizes 30fps game footage and duplicates frames to 60fps without smoothing or intermediate frame generation.
This issue is particularly noticeable at the beginning of the trailer, where the 30fps footage after frame duplication is worsened by a zoom effect.

Attached files:
- 3 consecutive frames: frame1.png, frame2.png, frame3.png.
- The difference between the consecutive frames: diff12.png, diff23.png.

In the attached files, you can clearly see that frames 1 and 2 uses the identical game footage frame, with only a slight zoom applied.
In contrast, the difference between frames 2 and 3 is significant due to camera shifts and changes in the positions of fast-moving in-game entities.
As a result, due to the irregularity of changes between each pair of frames, while watching the trailer at 60fps, the frames appear to be constantly twitching.

Please fix the trailer. If there is no available 60fps footage, at minimum, consider re-uploading the trailer in 30fps without frame duplication so that video players can handle it more smoothly.

Yeah, the quality of the trailer wasn't good. The constant movement made it hard to actually see stuff, but didn't know why exactly. 30 fps would explain that.
