Aliasing and edge cleaning

the MPG is a bad transfert from DV cam to dvd recorder (probably rca audio and 1/8 jack for video)

I can't reshoot this. i have lots of dvd transferd this way (not be me)

i know the whites are blown (IRE) (any alchemist are welcome if they can tranform lead into gold)

the Avi was made using this script -

OUT_SAR_X = 10
OUT_SAR_Y = 11

video = MPEG2Source("E:\DVD_VIDEO_RECORDER\DVD_RECORDER.in dex\DVD_RECORDER.d2v", cpu=6, info=3)
audio = NicAC3Source("E:\DVD_VIDEO_RECORDER\DVD_RECORDER.i ndex\DVD_RECORDER T80 2_0ch 256Kbps DELAY 0ms.ac3")
AudioDub(video, audio)

AssumeTFF()
ConvertToYV12(interlaced = true, matrix = "PC.601")

srestore(Frate=29.97)
ConvertToYUY2(ChromaInPlacement="MPEG2", matrix = "Rec601")
TemporalSoften(2, 5, 8, scenechange=15, mode=2)

Spline36Resize(720, 480)

i think it's a little over-filtred i'm loosing details (their isn't much)
i wanted to cleah up vertical and horizontal lines visibles around edges
i can see them well if i zoom to 400% (with virtualdub or aviuti)

my end goal is to make an edit-friendly file (probably prores422) for a 2 cam projet
i have another source that i've deshakened with enough succes

any suggestions?
