New with upload : export otion

Hi there I'm new with video stock , so I have few clips edited in Final cut pro , now it's time to export those and upload on pond5 via Cyberduck .
The question is : how do I should export the footage from FCP ?
So far I'm using Quicktime video codec , 854x480 , ....is it right ? or should I go higher resolution as 1280x720 ?

Am I doin right ?

Process it in the same size as the camera shot it. If the original is 1280x720 keep it that way. If it shoots in anything small than that ya really need to go buy a new camera and get one that shoots at least 1920x1080 HD. Really anything less than that is in very low demand. SO you really didn't give enough information for anyone to help much. Good Luck.

Yeah you're right , I did not give enough information : so I'm shooting with a Sony A6000 camera which shoot 1920x1080 , that's the resolution I normally use ....but there are so many otpion about exporting in FCPX that I'm getting lost , so I thought better ask here , and what the better format I should use since I'm uploading in Pond5 via FTP and on some other agency too

Thanks

Some one who uses FCPX can help with details but you want to process as 1920x1080 HD at 29.97 fps. Progressive, Quicktime at about 90% quality and either Photo JPEG or ProRes HD depending on what FCPX allows.

Maybe someone who uses that program can help better. Good Luck.
