transfer+videos+to+pc+without+losing+editing for example slow mo

Hello, I have downloaded the free version of this app to try as I am trying to find the best way to transfer edited videos to my PC without losing the editing or the editing transferring as file extension aae, separate from the original file. I have tried transferring a couple of videos with the app as I was told this was the best app to use specifically for this feature, yet, when I play the video once it has transferred, the editing (in this case slow motion) has been lost. Is this feature not available in the trial version or am I perhaps not transferring the files correctly? It may be worth noting that I am transferring these videos from within the 'slow mo' album on my iphone and not the camera roll itself. Not sure if that makes any difference. Thanks in advance!
