2. QTGMC (Avisynth) set "refined"
3. Press Avisynth Preview + 'Filter view enabled'
My config
Avisynth 32 bit
No Avisynth during CropView: enable
No Avisynth during Preview: disable

1. Starting Hybrid
   
2. Changing 'Filtering->Support' to 'Avisynth'
   
3. Loading a an interlaced source (using Base->Open File)
   
4. Setting 'Filtering->(De-)Interlace/Telecine->QTGMC Avisynth->Preset' to 'Custom'
   
5. Setting 'Filtering->(De-)Interlace/Telecine->QTGMC Avisynth->Source matching' to 'refined'
   
6. Enabling 'Filtering->Filter view'
   
7. Pressing the 'Filtering->Avisynth preview'-button and waiting,...
   
8. Avisynth Preview didn't open and the normal log showed:
   
   Avisynth preview error: -> Could not allocate video frame. Out of memory. memory_max = 1073741824, memory_used = 1046798796 Request=13187072 -> Could not allocate video frame.

9. Disabling 'Filtering->Filter view' and pressing the 'Filtering->Avisynth preview'-button while looking at the windows taks manager showed that avisynth was using ~1.8GB of RAM.
   Using Avisynth 64bit with 'Filtering->Filter view' enabled showed that avsViewer requires 47010,4MB of RAM.
   -> Nothing I can do about this 32bit applications simply can't use those settings and allocate that much RAM.
   So, how about changing the settings?
   Settings EdiThreads to 1 didn't lower the RAM usage, so that probably doesn't really help.
   Disabling MT lowered RAM usage to 2GB on 64bit and to 1GB on 32bit. (1.2 GB with EdiThreads at 2)
   => Disabling MT by enabling 'Filtering->Avisynth->Misc->Miscellaneous->Disable MT' works fine here.
   (there might be other ways to lower the RAM usage by changing other options)
   
   Good thing is I did find that I forgot to copy some files to the 64bit avisynthPlugins folder.
   -> I'll compile a new dev version (+ send you a link via PM once the build is ready an uploaded).
   So, you can either use 64bit Avisynth (which lacks a few filters which are not available as 64bit versions) or stick with 32bit Avisynth and disable MT.
