I have looked around and there are a TON of used/refurbished ipads for a C-note and thereabouts . . . very affordable, AND I have the leisure and comfort to record when I please . . . and maintain relative continuity.
I know nothing of what the RAM is capable of, but 32gb seems to be a standard.
Can 32 gb record the equivalent of an hour's worth of viewing? . . . I'd want to carry the thing around and record as I'm struck with a memory which should make for more interesting viewing/listening.
If this works out, I can purchase 5 (children) units and when it's all done (on my deathbed ? . . .why not? . . hmmm) . . . the one master will then be transcribed to the other 5.
.mpg was introduced in 1991. You can still play them with free add-on or convert them to MPEG-4 with free converters.
Even if the iPad doesn’t have the horsepower, to store everything, you can get yourself a USB connected one terabyte or 2 TB drive,, and offload everything to those. Just make sure you put a label on them to let your people know what they are for when you’re gone.
It’s a good thing to do, your family will appreciate it.
