Right - now this is probably going to be just a little awkward for even the best at compression amongst you. I've got a player (for a piece of hardware) that has a file-size limit ~8mb... It could be slightly under, so for the sake of argument lets say 7. I'm aiming to encode about 25-30 mins of video into that - and heres the VERY tricky bit - using the old DivX 4.12 codec and only the 1-pass version at that (unless the new ver of virtualdub is bad at doing 2-pass, the player seems to be incompatible with that method). I've got it down so far to 17mb at 320x240 (decimated by 2)... Decimating by 3 might give me some extra space, but I'm guessing not a massive ammount. So I want to know optimal bitrates and settings for the non-quality based version, or filters that I could use with the quality based one (or the other, too), that might let me set the quality/bitrate down to somewhere near 20% or 300 without losing watchability.
Tricky?
I expect so
Audio also needs to be in there - any filters I could use (and guides on how to use them) to allow me to use 22050Hz or 24000Hz 32kbs mono and not have it sound like crap. Or lower bitrates, even... but it has to be 22050 or 24000; I can't go down to the one below it as I think the player doesn't support it. Although I'll try it out. I think it only works with MP3s too, but since that's prolly the best sort of compression anyway, I'm not too bothered about that.
I may also reduce the size by splitting the files, but I'd prefer to get each section as long as possible before I do that (~15mins at least) as to move to the next section involves a minute or so of renaming. Which is annoying in mid-film.
Any hints/guides on how to do it would be very much appreciated - even if it only means scraping the odd few kb... if I can get enough methods to scrape a few, I'll manage...
