File size limitation on 360 footage

Hello fellow contributors,

i upload 360 footage, but regularly hit the 5GB file size limitation. I stick to the recommendations from the blog (technical: https://help.pond5.com/hc/en-us/articles/211162903-Submitting-360-VR-Media content: https://blog.pond5.com/15974-shoot-brief-360-vr/).

Therefore my clips are typically:
GoPro Fusion
~45 sec. duration (recommendation 45sec. - 2 minutes)
Quicktime Cineform 10bit (highest quality level from fusion stitching software)
Tripod removal in AE
Export as Quicktime Cineform 10 bit Quality levels of 2 or 3 out of 5. If i go with higher quality the file sizes will be way too big.

How can i avoid file sizes larger than 5GB? The recommendation says 45 sec. up to 2 minutes duration, so i do not want to go shorter, however reducing quality levels seems untypical for stock footage too?!

best regards,
Markus

try uploading a clip above 5gb and adding a note for the curator explaining why, maybe message pond 5, i have uploaded clips above the limit by a bit and had no problem try converting to apple pro res 422 to see if the file will be under 4gb
