2D Cinema Triple-Flash Mode for movie playback

I'd like to suggest a movie-focused enhancement that builds on the existing requests for 24fps support and FFTB support. A useful addition would be a 2D Cinema Triple-Flash Mode designed to better emulate the temporal behavior of a traditional 35mm projector. In film projection, each 24fps frame is commonly shown multiple times using a mechanical shutter. This does not increase the underlying frame rate, but it does change the cadence of light on screen and gives film projection a more cinematic, less sample-and-hold digital character. If the goal is to approximate real 35mm triple-flash projection as closely as possible, the most direct target may be: - 24.000 fps content -> projector runs at 144.000 Hz, giving 6 slots per frame - 23.976 fps content -> projector runs at 143.856 Hz, also giving 6 slots per frame From there, each frame could be presented as 3 light pulses by rapidly switching the laser light source ON and OFF while the underlying video frame itself remains unchanged. A simple reference pattern would be 101010, where 1 = laser ON and 0 = laser OFF. This would not use motion interpolation or create extra frames. The content would remain 23.976/24fps, with only the laser light output being modulated to emulate the cadence of projected film. As a related option, it would be valuable to also support a 2-blade / double-flash mode (e.g. 96 Hz for 24.000 fps or 95.904 Hz for 23.976 fps, using a 1010 pattern), corresponding to the traditional 48 Hz cadence used by some 35mm projectors. I understand this would be a 1080p-only mode, since the necessary refresh rates are not available at higher resolutions. I still think that would be worthwhile, since there is a huge amount of 1080p movie and Blu-ray content. Why this would be valuable: - gives films a more theatrical and film-like presentation - takes meaningful advantage of high refresh capability for movie playback, not just gaming - pairs naturally with proper 24.000 / 23.976 frame-locked playback - offers a worthwhile movie-focused option for users who care about cinematic presentation as much as raw resolution

I think the spirit of what you’re describing is essentially black frame insertion (BFI)? Literally turning the laser on and off so frequently sounds like a problematic/strenuous idea from a hardware and software perspective, and there’s no precedent from any other manufacturer as to how to achieve that. Comparatively: Generating a black frame in between frames and fitting it all into a high refresh rate output is less strenuous and technically something already been done so that XGIMI can simply borrow/study competitors BFI implementation such as JVC’s.

Yes, very similar concept - the spirit of the request is essentially a film-shutter-style BFI mode. My reason for mentioning light modulation was to describe the target cadence: approximating the way a film projector interrupts light between flashes. But I agree there could be different implementation paths. In practice, frame-locked BFI may achieve the same goal. Conceptually, it seems similar to 3D timing, but instead of alternating left/right frames, it would alternate frame/black/frame/black in sync with 23.976/24fps content. The main question would be whether inserted black frames produce a sufficiently dark interval compared with light-source blanking. If the visual result is effectively the same, then BFI would be a perfectly reasonable implementation path.

Love the idea if it works! I was a cinema projectionist for over 35+ years in the days of 35mm/70mm. The 35mm projs had a twin blade shutter, each frame would stop in the gate and the two blades of the shutter would block the light twice per frame. If this could be done on the TNM as a separate function it would be great!

Fantastic feedback and having the twin blade option would be a really nice addition

Interesting addition!
