70d 720p 60fps hdr video recording

Issue #2300 new
Former user created an issue

when shooting 60fps with the 70d using ML current version, it seems to skip frames. Trying to align the hdr footage is extremely difficult due to the frames not alternating properly between iso's so it's not always every other frame. I'd guess (and hope) it's a problem with the SD card (scandisk ultra plus 64gb).
