Single-pass limits are short: CameraCtrl 16 frames at 256x384 (AnimateDiffV3 build); MotionCtrl 16 frames at 256x256 (VideoCrafter main branch; its UI text says 14, a documentation inconsistency within one file) and 14 frames on SVD; CamI2V 16 frames at 256x256 or 512x320; Stable Virtual Camera 21 frames per pass at 576x576 default, with the authors reporting 80 to 134 frame sequences via chunking; GEN3C 121 frames per pass (121*N-1 autoregressive), example at 704x1280 while its model card says 720*1080; ViewCrafter 25 frames at 576x1024 (or 16 frames, or 25 at 320x512); Cosmos-Predict2.5 agibot 93 frames. Timings and memory in READMEs are the authors' statements (A100 40G for ViewCrafter; ~43GB for GEN3C with offloading) and were not reproduced. A 5 to 10 second previs shot therefore needs chunking or autoregression for every system except possibly GEN3C and SVC, and only SVC and GEN3C document how to do so.

Curator qualifications: Curator confirmed MotionCtrl mc-app.py builds n = 16 poses and a 16-frame noise shape while its UI text (L414) says 'A total of 14 lines'; GEN3C README vs card resolution difference kept.
