@jason.burich Just had to pipe up to say Chunking FTW!
I have a slightly different scenario where there was a need to have a pretty small file that I needed to continually append to, which adds up to a lot of data transfer.
Instead, I went with immutable, multiple attachments and never looked back. In theory, there shouldn’t be much of a hit from using multiple attachments versus a single one… However, I don’t know how long it takes to chunk and combine your videos.
