Did you really mean to call MCTD twice in fa()? You may be running out of memory.

yes

if i reduce the number of trims it works

how can i make it work ?

Using a random DVD MPEG2 video your script crashed on my computer too. But not after modifying it to use ReplaceFramesSimple():

Mpeg2Source(I:\VIDEO_TS.d2v", CPU2="ooooxx")

it works ! thanks

what does it do differently ?

my script basically tell use A or B in the different trimmed sections
your replaces or something ?

I think AviSynth creates a new video stream with each of your calls to fa() and fb(), 27 different streams, each calling memory intensive filters like MCTD and QTGMC. I'm my version fa() and fb() are called only once, so only two streams are created. If you modified your code to do something like:

Mpeg2Source("I:\VIDEO_TS.d2v", CPU2="ooooxx")
va = fa()
vb = fb()
return(va.Trim(0, 16785)
\ + vb.Trim(16786, 16817)
\ + va.Trim(16818, 17384)...

It probably would have worked.

It probably would have worked.

does your code does what my script intended? the parts with fa the default is applied to them and to fb the QTGMC...

it doesnt replace ALL of the trimmed sections with "fb" (QTGMC one) right?

Edit:nvm

[jagabo]

Why don't you just check it and find out?

[jagabo]

I had some time so I double checked my script in post 5. The last segment in ReplaceFramesSimple, [33980 37811], should be removed. The script in post 7 is obviously just a fragment -- you should be able to figure out the rest.

yes i figured it out myself and that you only used the "fb" frames

i already finished encoding

crap i forgot 2 sections that also has bad interlacing and need a fix.

[28819 28879][26199 26421]

the video is already encoded ...

what is the fastest way to fix this sections?

The best and easiest way is to add those two sections to the script and encode the whole video again.

what would be the downside by using something like this ?

LWLibavVideoSource("I:1.mkv") # "1" is the encoded video with the missing parts 
vb = fb()
ReplaceFramesSimple(vb, mappings="[28819 28879][26199 26421]")

Re-compressing the video will cause a loss of quality.
