# Which open-weight camera-controllable video or novel-view generators exist, and for each one does it take an arbitrary per-frame camera path, or only presets?

At the pinned revisions, all seven inspected systems take a camera trajectory as data; five accept free per-frame poses: CameraCtrl (16-pose RealEstate10K-style txt), MotionCtrl (one 12-float RT row per frame), CamI2V (RealEstate10K-style rows), Stable Virtual Camera (transforms.json, OpenGL convention, any number of target cameras) and GEN3C (per-frame world-to-camera matrices via NPZ or its GUI; the single-image CLI has presets only). ViewCrafter is different: it takes three short offset sequences (d_phi, d_theta, d_r, 2 to 25 values) and interpolates, so it is not a matrix-per-frame interface. Cosmos-Predict2.5 robot/multiview-agibot reads per-frame extrinsics and intrinsics for three fixed robot cameras, which is rig conditioning rather than a free camera path (the intrinsics files were not opened). Cosmos-Predict1 at the pinned commit has no file whose path names camera, gen3c, pose or trajectory (path scan only); GEN3C, built on it per its model card, is the camera-conditioned...

All statements describe released code/docs read at the pins; nothing was run.

Curator qualifications: All quoted excerpts located; seven systems take camera trajectories as data, five accept free per-frame poses (formats as listed). E13 is a bounded absence.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
