Hello,
I'm trying to get an image-orthicon effect on a clip, but not having much success. In fact, no success. In other platforms, you can achieve it by turning up the brightness slightly, cutting down the contrast by half, and applying unsharp masking at full saturation; in VirtualDub, that procedure causes a crash. Is there a easier way? A better way? Or is there no way? |

Unsharp is banished from my Plugins32 folder because it crashed so often. Here are some possible (untested) workarounds:
1. Prior to Unsharp, crop the frame to "mod16" (height & width evenly divisible by 16)
(most easily done with resize filter)
2. Try converting to YV12 (4:2:0) if it's not already
3. Try converting to RGB...
4. Use half-size unsharp radius on half-size image (for the same apparent unsharp radius)
5. Remove any unused filters from Plugins32.

The Kagayaki filter can be tuned to create nice blooming highlights, but I don't know if this can be made to work for you.
Avisynth can certainly do a halo effect; the demo script below will need refining, as I'm not sure of the look you are going for: | CODE | AviSource("path\to\your\video.avi")
ConvertToYV12(matrix="PC.709", chromaresample="spline16")
NonlinUSM(str=1.0, rad=16.0)
Tweak(sat=0.5)

## just for visualisation (step mode), you don't want the function to do this

Bit of a late addition
If that's the unsharp filter from http://neuron2.net/unsharp/unsharp.html
Then the 1.3 version seems to work fine
(looking at the sources, I can't see how the 'optimized' version could NOT crash - it's awful coding)

If anyone's interested, I fixed UnSharp and gave it a 50% speedup from v1.3

Thanks for looking at this. Unfortunately I ran into a problem:
- Win XP
- download UnSharp13a.zip, copy Unsharp.vdf to Plugins32
- open Vdub 1.10.4
- don't see Unsharp in Add filter dialog
- attempt to Load manually; got Virtualdub error and the following log output: | CODE | [!] Plugins: Failed to load "C:\Program
Files\VirtualDub\VirtualDub_1-10-04\plugins32\Unsharp.vdf": Cannot load
plugin module "C:\Program
Files\VirtualDub\VirtualDub_1-10-04\plugins32\Unsharp.vdf": The specified
module could not be found.
[E] Error: Cannot load plugin module "C:\Program
Files\VirtualDub\VirtualDub_1-10-04\plugins32\Unsharp.vdf": The specified
module could not be found.

Ach that's VS2013 not compiling for xp by default, I know there's a setting in there somewhere and I'll try and find it

Trying again in a fresh VM, I get the error message "MSVCR120.dll was not found..." Okay, which runtime do I need? |

VS 2013 c++ runtimes from http://www.microsoft.com/en-gb/download/de...s.aspx?id=40784
But you don't need to, I just had to change an option
Can you tell I'm still getting to grips with vs2013? 
It's getting to be a pain migrating from old files, you have to convert them using a few previous versions of VS and the settings don't always stay the same when you do
Doesn't help that I'm not a real programmer, my language of choice is Delphi and I hate c++ with a passion
(lets hope this one works...)
