Working with DV Video Files

I’ve been working with Shotcut for a little while now. Experimenting with all it has to offer. Still, I feel like a beginner. If I am editing a DV Video file, what settings would be best when exporting it? I do want to keep it as a DV file without making any changes to the original file (apart from the editing). If I export it in another format, what format would be most compatible with virtually all devices - HD television, Android, iPhone, etc.? Thank you.
