Claim: ARCore's Recording and Playback API records camera stream + IMU + custom metadata into an industry‑standard MP4 and then rewinds the file and treats it as a live session so tracking, depth and AR frames replay exactly. Works with ARCore and Unity; MP4 playback doesn’t require ARCore or Android if the player demuxes the custom tracks. Partners demo co‑editing apps (Voxplop) and carrier features (Jump AR); QA and iteration workflows drop repeat trips and device‑by‑device re‑captures, and the feature ships and runs end‑to‑end.
