Hello ML,
Is it possible to record video at alternating exposure rates per frame (1 frame at 1/48 @ ISO 400, the next frame at 1/400 @ ISO 3200).
Recording the above should be at 48FPS - alternating between 24 frames @ 1/48 and 24 frames @ 1/400
The idea behind this is to capture the slower exposure frames to be used as the video source (24fps at 1/48 - or whatever), and use the intermediate 1/400 (or faster) frames to significantly help motion capture tracking programs (this is aimed towards faster moving objects/scenes that generate significant motion blur). The 1/400 frames are there to freeze the motion - not to be used in final production, so the quality can be less-than-perfect.
If the image files are imported into a NLE using odd/even file numbers to distinguish, the separate rates *should* load into the correct video track (dropped frames may cause issues, but the frame details are stored in the metadata so all is not lost)
Offset the fast exposure frames correctly and the motion tracking points should be able to overlay the video track to be used.
Kind Regards
