@renroy-b You can transfer the videos digitally via FireWire (but this usually works only with old computers which have such a connection) or via an USB S-Video/Cinch-Videograbber which converts the analog video signal to a digital signal.
Install the adapter on your computer, then start the program, select the video/audio inputs and recording quality, start the playback and record it.

To answer your question, there are various options, all of which are reasonably complicated. If you have only a few tapes, I would suggest you find a friend or company which will do the conversion for you.
Re the cellphone, the basic process involves getting the video onto your computer, converting it to and MP4 file type, then transferring to your phone.
The options are:
1. Firewire transfer. This is the ideal process as it merely transfers video as opposed to capture, which involves recoding your video. Your computer needs a Firewire card installed, or your camcorder may allow transfer over USB, or you could buy a converter box. I have a detailed analysis of the DV/Firewire options on my website here.
2. Analogue capture using a digitiser such as the "Rescue Your VideoTapes" dongle that you have (I assume). In this case, you'd connect your camcorder to the dongle, then capture into Videoeasy as per the manual. For the video signal, using an S-Video cable will yield better results than the yellow Composite cable.
This is a user to user forum, not Magix support, responses to your post will depend on who is online and has the experience of importing video using the appropriate Magix software
With the little information you have given and assuming you have Rescue your Video Tapes and the video converter dongle - see this tutorial.
If you require more information then we need to know the camera make and model number, which output cables you have for it, and the full name and version number of the Magix program you have.
