More help with Multidecimate
Posted: Mon Jun 17, 2013 9:26 am
I use this lovely filter a lot, mainly to remove duplicate frames from 8mm telecine files prior to stabilising, and have arranged a smooth and efficient workflow.
I am having problems with a file which is not working properly in pass #1: mfile has missing frames at the beginning or the end.
The 8mm scan is done by Cinepost, with a Rank Turbo (truly high-end scanning!), is in DV-AVI PAL, but is interlaced with mismatched fields in VD. Your telecide filter fixes that, and I make and save a DV-AVI file (Cedocida 023) in VD.
I use this saved file in a simple script
avisource("C:\Users\me\Videos\Avisynth\yy12.avi")
converttoyuy2
multidecimate (pass=1)
load into a virgin VD then press Enter or "run video analysis pass", then immediately quit VD.
If I "dub", then mfile has the first few frames after 0 missing, e.g. 1-3 or 1-6. (Then of course the wrong frames are removed)
If I do a video analysis pass instead, the last few frames (e.g. 100 frames!) are missing. (The output stops before the end). VD's "progress" window indicates that these last frames are actually processed.
I thought I'd found a workaround by putting the selection markers at the beginning and end: worked once but now no difference.
Bit mysterious? To do with the Telecide? Be grateful for your help.
