hello i have several WMV movies with very good quality. When i import them to After Effects in my timeline and create my project, i export the movie again to WMV. However i do not get the same quality results. The final movie is less quality than the original one. Does this have to do anything with my WMV settings? If yes how can i get the best possible results?
Windows Media spec has 1 pass Quality rather than bit rate based encoding. 1 pass Quality 100 is "archival" (or as archival as WMV gets). It allows the encoder, rather than you, assign the bit for 100% quality. If you target a bit rate as is required in 2 pass encoding, there's no way for you to know assuredly you are getting the best quality. In 2 pass the encoder is targeting the bit rate you've assigned. In 1 pass Quality 100 you're telling the encoder you want maximum needed for best quality.
With WMV 1 pass VBR is Quality based encoding. 2 pass VBR is Bit Rate targeted encoding.
