How to upload slo-mo videos?

I have a big problem when I record with my iPhone 5s with the feature of the slo-mo when I want to upload to Instagram, Facebook, Vimeo, or sending on WhatsApp it appears like a normal video not as a slo-mo video.

Trying to convert itunes song to ringtone, file name not showing up with.m4a?

I make the song 30 seconds, create an aac version, hit show in windows explorer, but then the next step says change the ".m4a" in the song title file name to ".m4r".

How to get old photos from old iphone to my computer?

I have an iphone that is deactivated, does not sync with my computer or with itunes, doesn't have icloud for backup and I want to get my old photos from it before it explodes. It is an old 3gs phone with an outdated IOS.

I have tried the following:
- Connect iphone to computer to access hard drive
- Connect iphone to itunes
- Emailing photos to myself
- Uploading to cloud storage

ALL have failed and i'm running out of ideas. I don't think the proble has anything to do with wires/cables or my computer, it is just purely the old phone.

Please if you have any suggestions that has been proven to work, it would be much appreciated. I Really need those pictures.
