ok 1920x1080 as png.... omg that's huge even if only for a 10 second anim at 30 fps. You're talking 300 images in PNG format at 1920x1080 each, have you seen the size of that? You're not going to want to upload that. You can render at that size if your computer doesn't mind, but sharing and showing needs to be in reason  lol... put the image sequence into a WMV or mp4 or AVI with a decent algorithm for good compression (at least 50:1 ratio) without too much loss of detail, in fact for AVI there's a free codec called Lagarith, I use that one because not only is it well compressed and fast to do so, it' is in fact lossless.

 

PNG as an image sequence is good because it's lossless, so it's good when that matters. Not so good when size and time maters for uploading. Although there are some scenarios where PNG will excell with regards to compression ratio, such as with run-length scenarios, similar to when Gifs do well, you know, when there's only a few colors and many consecutive pixels at the same color, not every other pixel a different color.  In the latter case, PNG can be sure. SO if you render something with a lot of color noise, such as  grass, where every helm of grass makes the colors of nearby pixels quickly change from light to dark to shaded to highlight grey and green and flowers etc... it's noisy and thus png doesn't compress well, and files are big.

 

That said, I don't think I answered your question - sorry it's too early and the caffeine is just setting in.
