My recommendation would be to minimally sort your photos into various categories...family; vacations; special events; whatever fits your life. As you are going through that process, toss out the bad photos that we have all been convinced we need to keep. You know, heads chopped off; big old blobs of flash. Just toss them.
You really don't need to 'scrapbook' if that is not your thing. If you can, write on the back of the photo who is in them; where it was taken; when; whatever you know. You can get photo background paper already cut to most photo-ready sizes - a bit oversize. i.e., 4x6 photo would go on a 5x7 sheet. If you are worried about archival quality, you can mount the photos on those sheets with archival safe adhesives. If not, a glue stick on the corners of the photo works. Transfer whatever you've written on the backs of the photos to the back of the sheet it's mounted to. Or make that one process. But if you at least get some basics on the back of the photos, you've passed on the info to future generations without making a total production out of it.
Get some photo-style decorative boxes (or other size-appropriate decorative boxes) and toss the mounted photos in there with a label on the box as to it's initial category.
You could even type up the photo info onto adhesive labels to use on either the back of the photo or the sheet you've mounted it to if you feel your handwriting might be difficult for others to read.
And, frankly, I'd bite the bullet and have all the videos transferred to DVD whatever the cost. If DH is still working, it's not likely he'll get to that in the near future. If you at least get everything onto DVD, when those go the way of the dodo, you (or your heirs) will likely be able to get them transferred to the next generation of video file.
My dad did that with all the home movies (and had copies made for each of the siblings) after trying to view them on the old family projector and having the bulb start melting the film due to it's age.
Just my thoughts. Yes, it can be daunting and time consuming. It's like eating an elephant...just do it one bite at a time.
