Too much mouse work
Replay timing suffers when the operator must search menus, click buttons, and drag controls during live action.
vMix Replay Solution
Build a faster replay workflow without forcing the operator to chase the mouse.
For sports, esports, venue events, and live shows, the replay bottleneck is rarely only software. It is the operator loop: mark the moment, find the angle, control speed, send replay, then return to live cleanly.
Replay LoopCapture -> Trim -> Select Angle -> Play -> Live
A good controller turns this into muscle memory, especially when the show is moving fast.
Common Problem
Where vMix replay setups usually slow down
Unclear control mode
Customers often do not know whether TCP or USB-MIDI is the right starting point, so setup becomes more confusing than it needs to be.
No rehearsed workflow
The system may be technically connected, but the operator has not practiced the exact replay rhythm used during the event.
Recommended Workflow
Use KD61B as the physical replay surface for vMix
1
Prepare vMix Replay
Create the replay inputs, confirm camera angles, set the replay output, and check that recording storage can keep up with the show.
2
Choose TCP Or USB-MIDI
Use TCP when the customer wants faster deployment over the network. Use USB-MIDI when the operator needs deeper custom mapping inside vMix.
3
Map The Operator Surface
Put high-frequency actions on physical controls: mark in, mark out, play last event, jump to live, camera select, jog, and speed control.
4
Rehearse The Replay Loop
Practice the actual rhythm: capture the moment, trim the clip, choose camera angle, send replay to output, then return to live cleanly.
Decision Point
TCP or USB-MIDI: choose by workflow maturity
This is a judgment problem, not just a cable problem. Start with the mode that matches the customer's current capability.
vMix TCP
Best when the replay station and controller are on the same network and the customer wants fewer configuration steps.
- Network control
- No direct USB cable required
- Good for clean desks and IP workflows
USB-MIDI
Best when the operator wants more custom button behavior and is comfortable configuring vMix shortcuts and activators.
- Flexible shortcut logic
- Good for advanced operators
- Requires more setup time
Product Fit
Why KD61B fits vMix replay control
KD61B is not positioned as a generic keyboard. It is a replay-oriented surface for operators who need fast, repeatable control during live production.
- Dedicated replay controls reduce mouse and keyboard dependency.
- Jog wheel and T-BAR support frame search and slow-motion playback.
- Camera buttons help operators switch replay angles quickly.
- TCP, USB-MIDI, PoE, and custom buttons make the same panel useful in different production layouts.
Best Fit / Not Ideal
Best fit
- Sports and school events that need highlight replay.
- Esports streams that need fast clip playback.
- Live production teams already using vMix Replay.
- Operators who want physical controls for repeat actions.
Not ideal if
- The production does not use vMix replay functions.
- The team only needs basic scene switching.
- No one is assigned to operate replay during the event.
- The customer expects hardware to replace workflow planning.

FAQ
vMix replay workflow questions
Is KD61B only for sports replay?
No. Sports is the clearest use case, but KD61B can also support esports, concerts, education events, venue screens, and live shows where replay or highlight playback matters.
Should a new customer choose TCP or USB-MIDI first?
Most new customers should start with TCP because it is easier to deploy. USB-MIDI is better when the operator needs deeper custom shortcut behavior.
Does this workflow replace a vMix operator?
No. It gives the operator a faster physical control surface. The operator still decides which event matters, which camera angle to use, and when to send replay to program output.
What should be prepared before buying a replay controller?
Confirm the number of cameras, replay channels, vMix edition, network layout, operator position, and whether the team prefers TCP simplicity or USB-MIDI customization.
