Save yourself the trouble and buy a BMPCC or BMMCC.
So how are these to my already bought still versions that I absolutely love?
This would only work seamlessly if Vimeo didn't render the footage for an hour. I use wetransfer or google drive to send a cut for comments right now and it works well because I only need to send like a small ProRes LT version say 100-250mb and then get comments within 15-20min depending on length. This would disrupt the flow for sure sadly.
