AviSynth or Other De-interlaced method?

Post by xnamkcor » Fri Jan 23, 2009 11:15 pm

There was a certain way I've been de-interlacing my video game footage, and I was wondering if I could use a script to achieve it.

1) Record AVI
2) Discard Field 1
3) Export Frames as Images to Folder 1
4) Reload original video
5) Discard Field 2
6) Export Frames as Images to Folder 2
7) Batch rename Folder 1 Images (Start 1, Step 2)
8) Batch rename Folder 1 Images (Start 2, Step 2)
9) Copy Images from Folder 1 and 2 to Folder 3
A) Sort by name and drag into VDM
B) set appropriate Frame Rate and save

i don't understand what steps 7/8 are accomplishing... the way i'm reading it you are going to end up with twice the number of frames?

what are you using the capture the video in the first place?

S-Video
ATI AIW 2006
WM9CAP
VDM

If you don't rename them alternating filenames, they overwrite each other and you lose half your frames. When you discard a field you are left with a half height set of frames. Make a set of frames for both fields and you are left with twice the frames and only half the height. In my experience, I like how stretching 640x240 to 640x480 or compressing it to 320x240 in the player looks than using normal de-interlacing methods.
