1: Nope, reencoding it and increase the bitrate wont help. With some filters you might get "better" quality, like deblock and sharpening filters.

2: Nope.

Best is to find a better video source and then reconvert to the higher bitrate.

Start with a nice flat shiny piece of aluminum foil, say 12x12 inches. Compress it down to a 1 inch ball. Uncompress it back to a flat sheet. Note all the wrinkles (compression artifacts). Compress it again, but this time only to a 2 inch ball (less compression). Uncompress it again. Does it have more or less wrinkles?

I know - less . . . . , no - more . . . , no . . . .

I love the analogy
