1. depends on the source and your filters but if the source becomes less noisy then encoding might be faster though I guess less than 10% faster
2. surely

1. First read about noise patterns, then you may try googling for appropriate filters
2. This really depends on your source which might be a lot different than what others have posted on the net, so trialing might be a necessity. To save time you could take one clip, and encode a short part of it using different filters/filters parameters/encoding settings. If you're content with the results, you can proceed to encode the entire clip.
