.. to improve the quality in Virtual Dub you would need a lot of prep-work on the Videos long before encoding the final product.
.. yeah, it can be done but .. yeah, not knowing the Codec you are using can totally distroy any amount of Filtering that Virtual Dub might have cleared-up!
Almost any NLE editor/finisher can Optimize any codec when compared to Virtual Dub, and AviSynth can do a much better job with Video than any NLE editor/finisher.
.. Virtual Dub had its day of glory `years ago ... all we ever asked of it was to become a twin video line and tri-audio line editor and the creator would not do it .. let the old dog die .. AviSynth/TC is the new talk of the town
