I can’t make it any simpler than
[Craig Seeman] “Basic rule for all compression.
File size is data rate times duration.
“
Please explain what part of that is confusing. Honestly I’m keeping this very simple.
Using Firefox you can upload up to 20GB to YouTube.
[Erin McConnell] “When I attempted to send through the 7GB h.264 files created in the manner above, the recipients could stream it it in dropbox, but not download it.”
I’m going to guess they don’t know how to use dropbox then.
Given what’s going on I honestly think you should hire someone to do this for you and show you in the process. It really seems your in a deep quagmire (over your head) as a novice.
