LR6 will not import, and tells me my gopro mp4 videos have no audio or video component, yet they play ok and can be edited ok if I manually copy them onto my computer so they must be ok !
They worked with LR4, but not v6..... tried on 2 computers, Windows 8 and 10. Gopro jpgs import ok, but not mp4 videos ( from Hero 4, although that should not matter) MP4s from my other cameras are fine.
Same issue, used to work, now it doesn't. Did you ever find a fix?
Have the same issue, Windows 10, Lightroom 6.6.1. From reading a bunch of other resources, it seems to be related to codecs that LR relies from QuickTime. I have QuickTime 7.7.6.
Playing the video in QuickTime works well, but cannot import, or play mp4s anymore.
This is a pretty frustrating bug that hasn't been solved for months. Is there a way to contact Adobe Support directly to solve this issue?
Having the same problem with .mp4 files that played fine in an earlier version. Did anyone find a fix for this?
