Once the file(s) pass upload completion and post-upload validation they enter process state.
S3 Bucket Structure
All user uploads (and processed images) reside in a single S3 bucket.
The directory structure of the bucket is as follows:
this directory holds all raw uploaded files (jpg, mp4, 360)
DATETIME = datetime sequence was created
Processing steps are determined by filetype uploaded.
Until final image processing is complete, sequence is in Upload processing state.
If an error happens during processing, the sequence enters Upload processing failed state. Generally no errors should happen in this process due to input errors, as previous validations should have ruled out such errors
