Video and Audio documentation

Hi all,

I am getting ready for my annual redetermination - which I know should be just around the corner. In the past I have always submitted any extra documentation like photos, test results and the like by USPS Certified Mail with return receipt.

I have also wanted to be able to send video or audio documentation of to help support my case, in the past various caseworkers have told me they cannot open any external links sent via email to that rules out a cloud based option. And trying to submit by email in general will bounce back to to email limit size.

Does anyone have any experience with sending in documentation in the form of video and audio in a way that can be proven it was given to the caseworker?

Thanks in advance.
