failed to encode the video frame

Hi guys I am having so much trouble with this "failed to encode the video frame". I have watched you tube vids and still having problems,
Most you tube vids that I can find on the subject just say put the frame rate to 24 and it will work but I am still having problems delivering can some one please point me to a good video explaining this or tell me the settings I should be using. I am using dji cameras IE drone p4p and dji osmo 4k to film.
I think I have both set to UHD 2160 at 30 fps. Now I have to admit I am new to editing and this kind of stuff. I was using filmora video editor but need to move up to something more advanced now. Thanks for any help guys

Is there no one on here can help out with this topic?

ok so now I can export using youtube or vimeo at 1080 but still get the error code if i export at 2160.
I still cannot export anything in custom setting. Any help please

I believe that Windows 7 is not supported by DR.

That, and 3 GB VRAM is quite short for 4K.
Try a HD timeline.

I can edit and export now I just cant edit in 2160 or in custom.

Hey guys does any one know where I can get a copy of DR14 iwant to go back to it till I get a new computer.

Just scroll down.
