    So what's teh community's opinion on this topic. Personally i was going to go with PPMD on the best settign but then it was predicting 101% compression D:. So what's everyone's view? PPMD, LMZA, Bzip2, Winrar, what?

    Also time to compress is not a factor that's that large here. If it takes an hour but saves me 2gb i'm happy. I'll be making ~20-60GB archives here. And will be doing this till i can use my second hdd then i'll probably just put them over there and keep on rolling.

    Most video files are already highly optimized and do not compress further. I don't believe you'll see any significant difference between different compression algorithms (and the original file sizes).

    Well....the only thing I can really think of that can save lots of space is to reencode the videos with a lower bitrate.

    That would only not sacrifice too much quality if the bitrate was crazy high before but other than that.....not much

    videos aren't compressible... only way to make it smaller is to lose data, or use a more efficient codec

    i think h.264 is one of the codecs in the top range: high quality with low file sizes... trade off is that you need something relatively modern to decode them...

    Lower the bit rate by about 3/4, it will bring the video down to a lower size and still look as good.

    Also, check the compression settings and read up on video compression, there are many things you can tweak to get the file sizes lower and look just as good. I have uploaded videos on youtube less than 150mb in size and the quality is amazing. Check out the channel, Stay Well and Fire Your Doctor on youtube, most of the videos are in high def and lower than 150mb in size.
