Hello vMix Team and Community,

I’ve been a professional user of vMix Instant Replay for over two years in live sports production, and I greatly appreciate how stable and flexible the replay system is for multi-angle workflows.

I’d like to propose an enhancement that could significantly elevate vMix Replay’s capabilities:

🔹 Add AI-powered frame interpolation to generate super slow-motion replays from standard 50/60fps cameras, similar to what other systems offer, such as:
• e-Slomo by SimplyLive
• XtraMotion by EVS

This would enable smooth, detailed slow-motion playback from regular broadcast cameras, without requiring expensive HFR (High Frame Rate) equipment.

✅ Use Case
This feature would be incredibly useful in sports where dramatic replays (slo-mo goals, fouls, finishes) enhance storytelling and viewer engagement — even when operating on a limited budget.

✅ Technical Suggestion
AI-based frame generation could be handled:
• Internally in vMix, as a new effect in Replay
• Or exposed via the API to allow plugin developers to generate slow-motion clips using machine learning libraries like TensorFlow or NVIDIA Optical Flow SDK

🔄 Workflow Idea
• Replay operator marks IN/OUT as usual
• Presses “AI Slow-Mo” → vMix renders a slow-motion version using frame interpolation → saved as new camera angle or overlay

I believe this could open up a new frontier for vMix Replay users in professional sports and creative video production.

Looking forward to community feedback and hopefully vMix’s interest in implementing this.

You're asking vMix, a $700–$1200 software, to casually throw in a feature that systems like EVS XtraMotion and SimplyLive e-Slomo charge upwards of $13–18k for.
It’s like asking your Toyota to do 0–100 in 2 seconds like a Tesla Plaid, but still keep the fuel economy of a Prius.

Thanks for the feedback.

While it’s true there are standalone tools that generate slow motion externally, what I’m proposing is workflow-native, GPU-powered AI processing inside or alongside vMix.

The goal is seamless replay enhancement — not having to jump between software, re-import files, or rely on manual rendering.

With NVIDIA’s Optical Flow SDK and models like RIFE, we now have tools that run real-time on consumer GPUs, generating ultra-smooth motion even from standard 50/60fps content.

This becomes extremely useful in sports environments where adding emotional impact from basic camera sources is crucial — especially when true HFR cameras are cost-prohibitive.

And yes, HFR is great — but AI makes slow motion democratized, and I believe vMix could lead the way by integrating it smartly (even as a plugin or external module).
