AWS s3 upload + api too long

Question

I am currently using amazon s3 to store all objects such as images and videos. I am using the iOS AWS SDK to load objects.

Stream my application

• The user takes a picture or records a video.
• The user adds additional form information, something like Instagram Headline (using Alamofire)
• user clicks continue and then AWS will start uploading images and videos to S3 using the iOS AWS SDK
• After the object has been successfully uploaded to S3, S3 will respond with a link
• Finally, using Alamofire to send information, including a link from S3 as POST API parameters

The problem I am facing is that it takes quite a lot to complete the AWS + loading API call. This is a really bad user experience. Most images are less than 5 MB.

My decision

• Resizing an image, but what about the video?

• After the user clicks the Continue button, instead of loading the AWS + API call, why not do it as a background on another screen, so users don’t have to wait for the download indicator

What approach is suitable to solve this problem? Thanks

Resizing

You can simply show a warning that the file is too large (if> 10 MB for a photo or 100 MB for a video). Later, if you have enough time, you can always try resizing images / videos before uploading - not a bad idea.
