I think the Hero 8 records 4k60 at close to 100,000 which pushes even the best of memory cards, so it does very much sound like a card speed issueIt was after bringing it into lumafusion from my SD, a lot in the community are blaming my SD saying its not fast enough to write 4K 60 footage quick enough. SIGH! apparently GoPro recommends certain SD cards for faster reading. I bought one but wont be able to try it till Monday. I should load the SD card back on my GoPro and watch the footage to see if its any different
Looking nowim not sure if the software you have has this, but is there a "create optimised media" option anywhere? i know davinci has it, takes something from an unusable unworkable mess to smooth n workable in the timeline, worth a shot.
if the footage itself is jumpy it wont be savable that way, id set your camera down to 1080 till you can get a faster card for it. its never fun loosing footage, but atleast there was a bit of a leson behind it.Looking now
