Thresh and Partframes I did not change yet - they were as you set them initially.

The following kiddiescript is nothing compared to StainlessS' professional work, but it is a simple way to get you 80% of the way there. Here's the output file containing flash frame numbers:

Flash Frame.txt

And here's the simple script:

Code:
#Script to find flash frames

filename = "e:\flash_frames.txt"
global flashthreshold=0.8

i=AVISource("E:\Documents\Dnload\UNPACK\join3.avi")

j=trim(i,1,0) #Previous frame

# Temporarily un-comment next line to display the average luma value on screen to help determine threshold value
#ScriptClip(i,"Subtitle(String(YDifferenceToNext(i) ))" )

#This finds the FIRST frame in a series that fall below the threshold
#WriteFileIf(i, filename,  "(YDifferenceToNext(i)>flashthreshold)&&YDifferenceToNext(j)<flashthreshold", "current_frame+1", append = false)

#This line below will output EVERY frame that is below threshold, which results in LOTS of frames
WriteFileIf(i, filename,  "(YDifferenceToNext(i)>flashthreshold)", "current_frame+1", append = false)

#The line below finds the LAST flash frame in a series
#WriteFileIf(i, filename,  "(YDifferenceToNext(i)<flashthreshold)&&YDifferenceToNext(j)>flashthreshold", "current_frame+1", append = false)

Getting speeds on 2.4Ghz Core Duo duel core of (53:00 Join3.Avi clip):
Code:
00000002    541.76666260    [3748] InitDB: Completed in 541.21 secs (9.02Mins) : 176.31 FPS 
00000003    623.11572266    [3748] SequenceDB: Completed in 81.35 secs (1.36Mins) : 1173.00 FPS 
00000004    690.96984863    [3748] PartitionDB: Completed in 67.85 secs (1.13Mins) : 1406.35 FPS
Although InitDB timing previously gave me about 220FPS with debugging switched on, can only assume that my machine was doing something else
in the background during InitDB.

EDIT:
Not having a clue how to open *.webm I used below ConvertToAVI.Bat file together with ffmpeg (output UTVideo codec)

Code:
setlocal

REM Where to Find ffmpeg
set FFMPEG="C:\BIN\ffmpeg.exe"

REM Where to get input file, No terminating Backslash, "." = current directory (ie same as dir .bat file)
set INDIR="."


REM Where to place output file, No terminating Backslash. "." would be same as .bat file
set OUTDIR="D:\AVS\AVI"

FOR %%A IN (*.vob *.wmv *.mpg *.avi *.flv *.mov *.mp4 *.m4v *.RAM *.RM *.mkv *.TS *.y4m *.yuv *.webm) DO (
  %FFMPEG% -i "%INDIR%\%%A" -vcodec utvideo -acodec pcm_s16le "%OUTDIR%\%%~nxA.AVI"

)

Pause
