Flair FBX/CSV Offsets Checker — Browser Tool for Camera Path Visualisation and Nodal Correction

Summary

Tom D (tmd@tomdavid.com.au) built a browser-based tool that lets you drag-and-drop an .FBX camera file or .CSV export from the MRMC Tracker App to instantly visualise the camera path in 3D and play it back in real time. Beyond path inspection, the tool can remove false translation caused by an iOS device offset from the lens nodal point — recalculating and outputting a fresh downloadable CSV with corrected nodal positions. The tool runs entirely in the browser (no install, no server), and a standalone offline-capable HTML version can also be downloaded.

[RESOLVED] Tool Capabilities

Community — Tom D — March 2026

Tom D: "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."

Key features: 1. 3D path visualisation — drag-and-drop FBX or CSV, see the camera path instantly in 3D. 2. Real-time playback — play back the path and scrub along the timeline. 3. Nodal offset correction — enter X/Y/Z offset values (distance from iOS device to lens nodal point), recalculate the corrected path, and download as a fresh CSV. 4. Video sync playback — also plays back the associated video file (recorded by the Tracker App) alongside the CSV path in a side-by-side view. 5. Offline use — download the tool as a single HTML file and run it on any browser, including on an offline Flair PC.

[RESOLVED] The Nodal Offset Correction Use Case

Community — Tom D — March 2026

Tom D: "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). This way we record the data, but as we can never get the actual iOS device sitting exactly at the lens node (because it would be inside the lens!) this seemed to do the trick. 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."

Workflow:

  1. Record a move in the MRMC Tracker App and export the CSV.
  2. Open the tool in a web browser: https://tomdavid.com.au/FLAIR_FBX_CSV_Offsets_Checker.html
  3. Drag and drop the CSV into the tool.
  4. Inspect the path for any unexpected motion or bugs.
  5. Enter the measured physical offset of the iOS device from the true lens nodal point (e.g. +23cm Y, +14cm Z for a phone mounted on top of the camera).
  6. Download the corrected CSV with true lens node positions.
  7. Import the corrected CSV into Flair.

[INFORMATIONAL] Community Reception

Ben Myers: "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!"

Heiko Matting: "Wow, that could be very helpful!"
