Transferring clips

Hey everyone! I’m just now starting to mess with the clipping software on my steam deck and I don’t know what I’m doing wrong. No matter how I transfer them from my deck to my phone it speeds it up so my like 8 sec clip shrinks to 4sec. All of the clip is there it’s just sped up SUPER FAST and I don’t know how to fix it. If anyone has any suggestions please let me know! Thank you!
