Interpolate 25p Canon files

[akkers]

I have 25p footage from a Canon 70D DSLR. I am trying to put it through the frame interpolation script discussed below but it keeps reporting 'out of memory'. I converted the footage to DNxHD format and tried to put that through the script but that keeps failing as well (it cannot open that file).

Try using SetMemoryMax(1024) or less at the start of the script.

No, that has not made any difference. Virtual dub opens the script ok and shows the first frame.But if you try to play, save as avi or preview it comes up with error 'Out of memory'.

If you're using a multithreaded build of AviSynth try using SetMtMode(5,1). If that works, work your way up from there.

If you're not using a multithreaded build you may have a version conflict with all the filters.

No, that did not work either. I am beginning to think this is a filter issue. I know that the Canon compression is a bit of a bitch and heavy on resources. Here is the info on clip:

Did you try SetMemoryMax with lower values? That setting is somewhat counter intuitive. it limits how much memory AviSynth and its internal filters use. It does not limit the memory usage of 3rd party filters or the program opening the script. So the solution to running out of memory is to reduce the amount AviSynth is using. So try SetMemoryMax(200) or something like that. 32 bit programs are limited to 2.5 to 3.5 GB of memory usage under both 32 and 64 bit Windows.

As an experiment, try reducing the frame size before calling DoubleFPS2:

WhateverSource()
BilinearResize(720,400)
DoublsFPS2()

If DoubleFPS2() is running out of memory that may eliminate the problem.

If you are using other memory hungry filters try removing them.

I don't think decoding of your source is a problem. But try using a different source filter. ffVideoSource(), DirectShowSource(), AVCSource(), etc.

If you try all that and still have problem you'll need to look at software versions. I'm using AviSynth 2.6 (a beta build) and MvTools 2.

I ran out of time and did not get to the bottom of this. However, I managed to frameserv the clip from AP to VDub running the script. Only problem now is that I cannot directly output to my preferred DNxHD format (VDub does not seem to pick up the codec). I have to put out to Lagraith lossles and then convert to DNxHD afterwards.
