VRL Link is a two-way link between a remote performer and VTOKU Cam. The performer drives the avatar on your phone with their motion and voice, while you operate the camera in the real world. You can send your program back over the same link, so a VTuber performing from home can appear in a shot you are filming somewhere else.
Pricing. VRL Link is free to use right now, during the launch period. Planned pricing is US $14.99 a month, or included with Pro (US $149.99 a year) along with a commercial-use license. See pricing. The service is still in beta and setup may change as it develops.
VRL Link for Windows
VRL Link has two halves: the app on your phone, and the VRL Link desktop app on the performer's PC. The desktop app sits between Warudo (motion and voice) and the room the phone joins, and routes the returning program video and audio into OBS. The performer runs it on their PC; the camera operator only needs the phone.
You'll need: Windows 10 or 11, Warudo with a character loaded, and OBS for the return video.
VRL Link for Windows is in private beta. Email support@vtoku.com and we'll send you the installer and setup steps.
Once VRL Link is installed on the PC and connected to the same room, set up the phone side under Settings › VRL Link.
1. Pair the two ends
Both ends connect with a shared secret. On the phone, tap Generate to create one, then Copy it and share it with the remote performer over a private channel. They enter the same secret on their end. Anyone with the secret can join, so keep it private and regenerate it if it leaks.
No PC on the other end? A performer can also send just their face from any webcam with the VRL Link web sender, free browser tracking that joins with the same room key.
2. Connect and receive the performance
Turn on Connect. The phone receives the remote performer's motion and voice, and the avatar lip-syncs to it. Two controls smooth the incoming motion:
- Offset, adds delay (up to 600 ms) to line the motion up with audio or a switcher.
- Smoothing, evens out jitter on a less stable connection.
To hear the remote audio on the room speakers or an interface, turn on Monitor PC audio and pick the output device.
3. Send your program back (optional)
Once connected, return this phone's program to the remote end:
- Send video, sends the composited camera view back, with resolution (540p, 720p, 1080p) and bitrate controls.
- Send camera, sends the camera move so the remote scene matches your shot. VRL Link carries this over VMC.
- Send audio, sends a microphone back to the performer, with a mic picker and bitrate control.
4. Show the return video in OBS
On Windows, VRL Link hands the returning program video to OBS over Spout, a local GPU texture share, so it stays on the one machine with no extra network. You need the Spout2 plugin for OBS to receive it:
- Install the OBS Spout2 plugin (Off-World-Live), then restart OBS.
- In OBS, add a Spout2 Capture source.
- Set its sender to the VRL Link program output (listed as "VRL Bridge Program").
Return audio (the performer's voice and your operator mic) is sent to separate output devices that you capture in OBS, so you can balance the mix in your own software.
Remote OBS? Spout is Windows-only and same-machine. If OBS runs on another computer, switch the video output to NDI and add a DistroAV NDI source instead.
When to use VRL Link vs. Warudo
Use Warudo when the performer and the PC are on your local network. Use VRL Link when the performer is somewhere else entirely: it carries motion, voice, camera, and video over the internet in both directions, with no shared LAN required.
Troubleshooting
- Avatar doesn't move: confirm both ends entered the exact same secret and that Connect is on.
- Motion lags or jitters: raise Smoothing, and use Offset to realign it with the audio.
- No remote audio: turn on Monitor PC audio and check the selected output device.
