Hi Guys
Thought I would bring this issue to the Club of Knowledge
Has anyone any ideas, 5.1K video is jumpy and will not play on my pc properly tried 4K out but still a problem
Do you have to have a faster SD card I use V30 Extreme Pro
Any ideas would be appreciated thanks
Sounds to me like the card should be just fine for that. What about your PC? The H.265/HEVC can be pretty demanding, so if you don’t have decent CPU, GPU, & RAM, that can often lead to stuttering.
Thanks @KarMann it was maiden flight to be honest so need to re test as may just have had a setting wrong but thank you
How old is your pc?, as said above could be your pc just isn’t fast enough to deal with the file
Agree with above, sounds like the computer.
Are you playing it from the card, or have you copied it over to the hard drive, rather than the cloud?
Hi guys
Many thanks for your replies, just thought I am playing from an external hard drive ? Could that be an issue? 4 K always runs ok PC is a few years old but quite a top spec ex gaming computer
Could well be.
Copy it to the hdd and see if the problem remains.
Will do thank you 
Upload a file and let someone see if if plays on their setup ?
Will do later thanks Chris
Hdd too can be slow believe it or not. I only use hard drives for storage because SSD have become so affordable and the speed is exceptional.
Okay the physical drive rather than an external drive.
A lot depends on how it is connected. USB A v C is a world of difference
I agree, good point,
This is one of those things that could be any of the above.
If you want to test physical media, blackmagics disk speed test is a good tool for video (leave it going a few runs with large files to stress test).
(Disk Speed Test is part of the Desktop Video package)
This will let you know if there’s a storage bottleneck. A V30 sd card should fine though, read speeds generally being better than write speeds. Have had dodgy cards from certain retailers though, so worth checking.
As others mentioned, it could be h264/h265 encoding. It’s usually the player though. VLC often struggles, so worth trying a different player. I’ve experienced jittery VLC playback of files from mini 3 pro on a system that plays back RED raw and ProRes 4444 etc no problem.
If it’s a CPU or GPU bottleneck, you can run a resource monitor and see if anything is maxed.
If you’re working in an NLE, sometimes mixed project rates can cause issues, for example, if your footage is 60P and you’re working in a 24P timeline, because it’s working double time to decode the footage and conform to the different frame rate. Offline / proxy workflow can help with this.
Thanks all for your support a friend tried files on a powerful Mac , same issue so going to do a re test flight when weather permits but all this info is great will update
Just a thought if it was shot in 265 it doesn’t play well on Mac
I’m sure it was H264 but will do a retest as was first flight so will get all settings dialed in and feedback soon as @milkmanchris
If you open it with VLC, you can find out the info on the codec used …
