I took a 4k video on my z5 and it played back in great quality on my phone and on whatsapp when I sent it to someone. I checked on whatsapp from my laptop as well and it looked good but not great which I expected. Then when I tried to upload it to my google drive it took an hour and then the playback quality was really poor. It's only a 1 minute video of around 350mb. Is there a way to fix this? thanks
