Most editors have a sharpen filter but that will just exacerbate the issue with the blockiness. The blockiness is called macroblocking and is caused by a low bitrate. Essentially most of the video data is gone. you can't fix what's not there.

You can remove the blockiness by reencoding at a higher bitrate with a soften or a blur filter but that will result in more detail loss where there is no blockiness.

Nothing wrong with experimenting.... Just find a part that's bad and trim it so it's short and work on that. Save you a lot of time.

Double deinterlace and heavy NR.
But that'll soften it.

You can try the MSU Deblock filter before doing anything else to it.

You can try a filter chain on virtualdub. Then you judge if it is worth it

MSU_Deblocking to de-block
MSU_Smart Sharpen (overall & boarders) to sharp it
