By scripting all your filters in AVISynth you can avoid many color conversions. The optimal scenario involves only 2 colorspace conversions: MPEG2 from DVD in YV12, processed with Avisynth in YV12 and then converted to RGB32 ready for editing. RGB export form editing program using Huffyuv in RGB mode and then converted to YV12 ready for the final video compressor. By doing this you not only save time but also quality by avoiding colorspace conversions.
Many people once used YUY2 mode in HuffYUV all the time thinking it was lossless - so they would import into Premiere, edit, export to YUY2, import again, edit, export again and each time it went into Premiere it was being converted into RGB and each time it was compressed to HuffYUV it was being converted to YUY2. This has lead to many faded-looking videos in the past.

When converting it displayed the output for audio as 25meg, is that normal? and is there a way I could decrease it?
