Posted to DJI forum, but no one has attempted to replicate issue yet. Would appreciate others trying please...
PROBLEM EXPERIENCE
Wasted a whole afternoon shooting a commercial job, high res panoramas (to get big files) of 8 images x 5 AEB (tricky llighting) = 40 frames each panorama.
Downloaded the files and discovered numerous AEB sets missing? A wasted 300km round trip and 1/2 day of work. Very annoying.
TEST
Ran tests in studio shooting 5 frame AEB's as fast as possible for over 100 frames (20+ AEB sets) and discovered a problem.
RESULTS (5 frame AEB groups. 'x' = missing frame)
11111 - 22222 - xxxxx - 44444 - xxxxx - xxxxx - 77777 - xxxxx - xxxxx - 1010101010 - xxxxx - xxxxx - 1313131313 - xxxxx - xxxxx - xxxxx - 1717171717 - xxxxx - xxxxx - xxxxx - 2121212121 - xxxxx - xxxxx - xxxxx etc etc*
CONCLUSION
P4P DUMPS full sets of buffered AEB files in favour of NEWER AEB sets? This is a software failure
This is highly problematic as the controller gives audible feedback when frames are taken (click x 5 etc) but does not indicate when the buffer is full. Cameras mustl stop taking more images until there is buffer space (or files are written), but DJI chucks all of them out?! There is no way, that I know, to tell if you have images written to card memory except to wait a very conservative time between shots, otherwise you will have missing frames. Not good.
REQUESTS
1) Can others please try replicating this test and report results?
2) Can DJI please check that this bug? I can't imagine 5 shot RAW AEB buffering is commonly tested, and may have been overlooked?
*The card was a Sandisk Pro 64gb U3, but similar results with other cards. Image files 2:3 format RAWs.
** Before you suggest it, no, using jpegs instead of RAW wasn't an option.
