Should I be able to edit an already saved curve? When I import an .amp file I drawed earlier and switch the curve type on the right side, the filter resets the curve.
The problem with an .amp file is, that it does not store the coordinates, only the raw data. When importing later it will switch to freehand mode. For a later version an interpolation when going from freehand to spline is planed, but even then it is not certain, that you will get the original curve and coordinates. If you want to store the coordinates, you can export to .acv. This format stores the coordinates only. So if you work with coordinates you should export to acv and amp. Or you can store the processing settings in VirtualDub (vcf). There all data is stored. The crv and map formats from Corel Draw are much more complete, but currently only import is possible. To the csv export I will probably add all the other data (coordinates/drawing mode...) in a later version. Currently it only stores the raw data in text format. The gimp format is somewhat borked also. Raw Data is never stored, so if you store a freehand curve and import it back in you will get a differnt curve. They also changed the interpolation from 2.2 to 2.4.

Regarding the bug, I got it nearly fixed...

For me, one of the by-products (to a greater or lesser degree) of bob-deinterlaced DV that most detracts from a 'filmic-look' is the flicker (shimmer, 'inter-line twitter', 'moire') on high contrast edges and patterns (stripes etc). Once again, Didee has come up with a marvellous function (TempGaussMC) that deals very effectively with this. Check it out:

Probably you're trying to load the .AMP file without "photoshop=true".

Try this:
GiCoCU("curve.amp",photoshop=true)

A bit late to mention this, but I just stumbled across a great paper from the BBC which discusses "the film look" in detail...

http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP053.pdf

It goes through transfer characteristics in great detail, also MTF, motion judder, depth of field, and aperture correction.

Cheers,
David.

If, anyone is (still) interested in 'film looks', I've put together this script for 'Bleach Bypass'. All processing in YV12.
