FBX & CSV Camera Path Viewer

CONFIRMED FLAIR CLASSIC + FLAIR 7

Summary

A free browser-based tool created by Tom D (Robotface Studios, Australia) that lets you drag-and-drop an .FBX camera file or a .CSV export from the MRMC Tracker App to instantly visualise the camera path in 3D and play it back in real time — no Maya, no Flair, no installation required.

Beyond basic path visualisation, the tool also corrects for iOS device nodal offset: if the Tracker App was mounted on a camera (rather than exactly at the lens nodal point), you enter the physical offset distance, and the tool recalculates the true lens node positions and outputs a fresh corrected CSV ready for import into Flair.

Access the tool: https://tomdavid.com.au/FLAIR_FBX_CSV_Offsets_Checker.html

Offline version available

A downloadable single-file HTML version is linked at the bottom of the tool page. This runs in any modern browser on an offline Flair PC without needing an internet connection.

What It Does

Feature Description
3D path visualisation Drag-and-drop an FBX or CSV file to see the camera path rendered in a 3D viewport immediately
Real-time playback Play back the path in real time, or scrub along the timeline frame by frame
Bug and anomaly detection Spot unexpected camera jumps, axis glitches, or corruption in the data before importing
Offset import planning Visually understand where the path sits in 3D space and think through the translation offsets needed for Flair import
Nodal offset correction Enter X/Y/Z measurements (distance from iOS device to lens nodal point), recalculate the corrected path, and download as a new CSV
Video sync playback Load the associated video file recorded by the Tracker App; it plays side-by-side with the 3D camera path visualisation
Offline use Download as a single HTML file; runs in any browser on any machine, including an offline Flair PC

Why It's Useful

When working on set with the MRMC Tracker App, there is no quick way to verify that the exported CSV or FBX file actually contains sensible data without opening Maya or Flair. Field operators often discover move errors only after importing — wasting time.

This tool gives you an instant field check in any browser:

  • Confirm the move was captured correctly before leaving the location.
  • Identify axis flips, scale errors, or corrupted frames.
  • Understand how the path relates to the robot's coordinate system before you commit to import settings.
  • Correct for iPhone/iOS mounting offset without needing to open any software.

The nodal offset correction also solves a practical problem that has no clean solution in Flair itself: the Tracker App iOS device physically cannot be placed at the exact lens nodal point. If it is mounted on top of a camera or on a cage, every recorded position includes an error equal to the offset distance. This tool removes that error mathematically and produces a corrected file.

How to Use

Basic path inspection

  1. Open the tool at tomdavid.com.au/FLAIR_FBX_CSV_Offsets_Checker.html
  2. Drag and drop your .FBX camera export or your Tracker App .CSV file into the drop zone.
  3. The camera path appears immediately in a 3D viewport.
  4. Use the playback controls to play the move or scrub through it.

Nodal offset correction (Tracker App CSV)

Use this when the iOS Tracker App was mounted on the camera at a known physical distance from the lens nodal point:

  1. Record the move in the MRMC Tracker App and export the CSV.
  2. Drag the CSV into the tool.
  3. Measure the physical offset of the iOS device from the actual lens nodal point:
  4. Example: phone mounted on top of camera body — +23 cm in Y (height), +14 cm in Z (forward/back).
  5. Enter those offset values into the tool's offset fields.
  6. The tool recalculates the corrected camera path showing true lens node positions.
  7. Click Download to get a fresh corrected CSV.
  8. Import the corrected CSV into Flair.

Adding video playback

If you have the video file recorded alongside the Tracker App session:

  1. Load the CSV into the tool as above.
  2. Load the associated video file using the video input.
  3. The video and 3D path playback in sync, side by side — useful for confirming the move matches the original camera action.

Evidence

"For anyone interested, I've built this tool that allows you to drag and drop an .FBX camera or a .CSV file output from the MRMC tracker app and instantly see the camera path in 3D and play it back in realtime or scroll along the path. A quick way to look for bugs, unexpected camera movement and to assist you plan your import into flair and get you thinking about import offsets etc. The App runs in your web browser and you just drag and drop your CSV or FBX file into the box." — Tom D, WhatsApp community chat, 17 March 2026

"It is also a tool to remove false translation from an iOS motion-sensor offset and outputs true Lens Node positions into a fresh downloadable CSV file. For example, a specific scenario popped up recently when a DP wanted to shoot a scene with ARRI camera on shoulder, but have the robot repeat the moves for plates. So we mounted the iOS device to the camera and I used this app to translate the movement of the iOS app back to the position of the actual lens node (ie, tracker was mounted on top of camera, so it was 23cm above the lens node, and 14cm behind it). You enter your offsets into the app, it calculated the new camera path and you can download the revised CSV so that robot receives the actual lens node positions, not the position the iOS was mounted." — Tom D, WhatsApp community chat, 17 March 2026

"This is awesome!! I tried something similar by importing the move into Blender, attaching a camera to it as a child, putting in the offsets, and exporting the new camera path. Definitely going to try this out!" — Ben Myers, WhatsApp community chat, 17 March 2026

"Wow, that could be very helpful!" — Heiko Matting, WhatsApp community chat, 17 March 2026

"I've added playback of the associated video file (shot within the tracker app) alongside the csv file. This plays back side-by-side with your camera path visualisation. Also added a download link at bottom for anyone who wants to run this on their offline system. Its built as a single HTML file, so should run on your offline browser just fine." — Tom D, WhatsApp community chat, 18 March 2026

"check it out @assaff @matthew" — Gordon Eschke (MRMC), Talk.MrMoco forum, 17 March 2026

"That's really good Tom. Thank you for sharing. I am sure it will come in handy for a lot of people as and when needed for different projects. Well done!" — assaff, Talk.MrMoco forum, 17 March 2026

About the Author

This tool was created by Tom D from Robotface Studios, Australia — a Bolt operator and active member of the Flair community chat since 2020. Tom built the tool to solve a practical field problem he encountered on his own shoots, and released it to the community for free in March 2026 as a browser-based web app. The forum post was acknowledged by MRMC Admin (Gordon Eschke).
