I want Virtualdub to remember settings for window size, and video preview size.
I want filters that have a preview window to be able to toggle the filter on/off so you can compare with the original.
I want the preview window that some filters have to be resizable or at least halved if required.
I want to be able to choose the range of frames a filter is applied to and I want to be able to have different filter settings for different ranges of frames without using a separate, complex filter to do it.
I want to be able to choose the frame that a filter with a 'sample frame' feature uses.
I want a filter that will apply auto colour/levels/thingy adjustments to a sample frame and display what settings have been applied so you can use the setings as is or modify them and apply them to a range of frames or the whole video.
I want it all, and I want it NOW!  |

Let's assume his last line is a bit of dry humor!
About that final request: you need Jim Leonard's White Balance filter. Here is the text from its help/description file:
==== clip =====
White Balance, Deinterlace, HSI, Brightness, Contrast
This filter started from a need to quickly/easily adjust white balance. Then I kept adding those color-content adjustments I frequently use so they could be accomplished from one filter using a single preview.
This filter does any of the following from one interface:
1. Deinterlace (interpolation)
2. White balance
a. Automatically attempts to figure out what should be white using 4 sampling algorithms
b. or accepts a custom RGB value that you want to force to white
c. Black adjust option attempts to compensate if dark colors are shifed too much
4. Hue, Saturation, Intensity using methods adapted from Donald Graft's excellent HSI filter.
5. Brightness
6. Contrast
=== clip ===
I second the request for the ability to toggle any filter on and off while looking at its preview window, in order to see what the video looks like with and without the filter applied. Currently you have to exit the entire filters area to do this.
I also second the request for a resizeable preview window for most filters that have one. I assume this is probably up to the filter developers, not the main man. |

I don't mind. $100/hr, 20 hr minimum.

Slight problem here... the filter config dialogs are modal, and they are created by filters themselves. I suppose a multithreaded hack could get around this, though.

No, this is a main program mod. Filters know that the preview is up but they can't control it and don't have a handle to the window; it's entirely managed by VirtualDub itself. Resizable preview windows are on The List™.

You can. It's the frame currently being displayed in the filter preview window....

Thanks, phaeron! I figured there were probably good reasons related to the current structure of the program, for why you had not implemented the two features that I was seconding.
The one about being able to on/off toggle a filter while looking at the preview window to see the video either with or without the filter's effect is REALLY important. I couldn't live with Photoshop, for example, if it did not have this basic ability in nearly all of its effects and filters. So one day I do hope that a hack or even a major alteration is made to allow this.
Additionally, what really has made Photoshop extremely powerful since version 5.5 or so is the ability to take the most recently applied filter and cut its effects by a percentage. In other words a program-level ability to alpha-blend the video stream before the filter ("dry") with the post-filter stream ("wet") by any percentage, chosen with a slider while looking at a preview frame. Furthermore, Photoshop allows you to do this not just in the ordinary RGB mode, but in your choice of ways including alpha-blending only those pixels that were lightened by the filter; only those pixels that were darkened; or many other modes that allow for a lot of creative possibilities. Just a thought... |

It's funny, I don't seem to be too bothered about those features now.
Thanks for the answers chaps. Of course, Virtualdub is fantastic as it is and I put these requests in a light-hearted way.
A couple of things though, I can't get the preview windows to show anything other than the first frame so I'm not sure what I'm doing there.
endorphin, I've already got that filter which is great for what it does, but I've tried the ACDseeEOD filter which is a nice quick way of improving colour balance and levels automatically, but it works on each frame individially and so the settings can shift during a clip depending on the content. I'd love to see a filter that works like this one but lets you freeze the auto settings for a range of frames. Or something like that anyway. Still, that's not really a virtaldub request more a filter request.
phaeron, how about remembering the maximized setting when opening virtualdub? Is that something you could slip-in in the future?
Also the preview window size. It's just a couple of things that need changing whenever Virtualdub is started that would be nice stored in a setting somewhere. Maybe it's my 15" 800x600 monitor that's the problem. Can't justify a new one at the moment.
Oh, please tell me if you know what I'm doing wrong to always get the first frame in a preview window. Thanks again.

If you want your VD window to always be maximised, try editing the shortcut itself. Bring up the shortcut properties. There's a drop-down list there called "run" that contains the value "normal window". Just change it to "maximized" and click OK. The next time you start VD through its shortcut, it'll be maximised on startup. |

Nice one Kippesoep! One of those things that seems so obvious once suggested but which I would never have though of. I can think of a few other programs I could try that on as well. Thanks. |

I see...
Good idea and now i see what you're asking for more clearly. But the White Balance filter does allow you to choose a single sample frame and then use the settings from that frame for the rest of the clip. What then are you still missing? The ability to adjust in color spaces other than RGB?
It would be great if the ACDseeEOD filter could be rewired so that it allowed the color balance parameters to be smoothed over an entire clip so that they changed gradually from frame to frame and never flickered. However I assume that would require either 2 passes or some sort of fancy mandatory preview + logfile writin, or a full non-linear-editing package. |

Well, as far as I understand it -- which may not be far enough -- the white balance filter lets you sample a frame and has presets to favour red, green, blue or luminance. These settings don't always have a desired effect You can enter the settings manually for what you want to be white, but that's back to manual settings again. Also -- and I'm not too sure of the technical side of it -- the ACDseeOED filter seems to correct the 'levels' settings as well. By this I mean the same as the levels filter in virtualdub where the darkest and lightest settings are expanded. I think that's what's happening though I'm not as clever with these things as other people here seem to be. I can only say what it looks like is happening to me.

Yes, that sort of thing would be great. Or averaged the settings and applied that to the whole clip with no change. I don't think anyone's working on this filter now though are they? I've no idea who wrote it.
Oh, does anyone know how to set the frame to be 'sampled' on filters like the white balance filter? I always get the first frame on the preview despite setting a different frame on the playback window.
Many thanks.
