How I can change some default settings in AVS script? For example, I want to use Spline36 instead Spline16, AssumeFPS(25) instead DG pulldown and add hard-coded subtitles before resize (subtitles look fat by default). There is also ConvertToYV12() even if video is already YV12. Don't know it that conversion degrade quality or reduce speed in this case, but I remove it everytime just to be sure.
These can be done manually but it is quite annoying to change them for each video.
Is it possible to do PAL 4% speed-up for audio inside AVS script which AVStoDVD accepts? For now, I convert audio tracks with audio editor and it is quite annoying task.
