HD Video Material - Long Term Storage
The more I think about the long-term storage of video material the more confused I get and the more difficult it seems to be to preserve the very high-quality original files that are generated by recording in 1920x1080p resolution. The problem to me seems to be that the original files aren't really that large but you can't satisfactorily edit with them and the working files that you have to generate in order to edit the material properly are extremely large and essentially impossible to store for the amateur user. I overcomplicate things even more for myself by having this desire to always to be able to go back to the original material if I want to re-edit it for some reason and this gives me added storage complications.
For some while now in my HD video camera I have been using 16 GB capacity cards and this allows me to store well over two hours of material on a single card, this is actually far more than I ever practically need for a single project.
Given that any standard DVD will hold over 4 GB of material I am seriously considering switching to using 4 GB memory cards, each of which will hold about 25 minutes worth of original compressed HD video. My theory is that if I go down this route I can simply keep all the original files from a particular project on a DVD, I can then generate the working files from that and do whatever editing I want to do, and finally I can delete the working files and still retain my original reference DVD and recreate the working files from that in the future should I need to do so.
This may sound like a long winded approach but at least it will always allow me to go back to the original material and will satisfy my desire to not throw anything away!
