About the scope:
I know that is it very usefull, but I don't usually use it with Vdub, although it would be really usefull in conjunction with the Levels filter.In fact being inside it would be a better way to go IMO.
Where I would really use a vectorscope would be to monitor a DV camera through firewire without the need of using Premiere of FCP in a Laptop, just the little application that transforms my laptop monitor into a Wavefrom and Vectorscope monitor.
Think about it, you could make it a commercial product and get some bucks!!... |

I actually do use it within the levels filter. Add Levels. Add WFM. Go back to levels and do a preview. You can see the WFM and adjust the levels. I'm going to add active preview next. I looked at this and it seems easy to do.
On the 'bucks' thing....  I'd say the best way to describe my programing skills is "don't quit your day job!"  I believe there is a product called VScope that may do this for you. It connects to a capture device and displays a few scopes of the signal. As I recall, firewire cams show up as devices in my directX capture app. I'm not sure how all of this works, but VScope may be usable with a firewire cam.
---------------------
Also, I did rework the code a little so that it works with avisynth. I posted a usage script at doom9.

The last time I tested Vscope it didn´t work with Firewire....just analog inputs... |

@trevlac: Although I've made a number of suggestions in the past, I'd like to circle the wagons a bit and revisit some suggestions (and new ones).
For some of the really tricky things I'm doing, it would be REALLY REALLY REALLY helpful to have the last settings saved somewhere. I'm having to add the filter many times, each to many simulaneous instances of Vdub. And each time, I have to turn off the R, G, and B, and turn on the WFM. Won't you please consider stashing them in the registry somewhere, or letting the user set up an .ini file or something like that??
Linking directly to the .vdf file is not a good idea. It really should be part of a zip file for several reasons. 1. It would ensure integrity of the .vdf file for those with less than perfect modem connections. 2. You could have a small readme file in it, which has your version number. This is important, as when someone goes to get your current version, they shouldn't have to download it, open Vdub, load a video file, and goto 'add a filter' in order to find out what the current version is. Or have version number as part of the zipfile's name. (But not the .vdf's name.)
And most importantly, we really need to somehow get your file out to the masses. Do you think you could submit your filter to Donald Graft for inclusion in his list of "other" filter sources? This is too important to keep buried away in this isolated message board thread. |

TC,
My work is crap. The more I do, the more I realize how little I know.
I'll see if I can do some updates. Anybody else want to do the code ? I did figure out how to hook into vdub and add the scope to the main menu. From there you could conceivably open a seperate preview window. But you gotta take care of a bunch of things. I'd like to be able to 'steal' avery's preview window. I'm still learning this coding thing.  Maybe I should switch jobs, cause I don't do that for a living. Just late at night when the family is all in bed.  |

Trevor,
NO NO NO! Your filter is NOT crap! I've haven't seen the code, so perhaps you're saying the code is written ugly or sloppy or with style that lends itself to bugs. But the concept of a WFM is NOT crap, and is terribly important to good video. And the fact that yours WORKS is what makes it worthy of this praise. Yes, maybe a seasoned C programmer could totally rewrite it in a cleaner fashion. Yes, he could make enhancements much easier. But NOBODY has written such a tool as your before. And now that you've done it, my video life has taken on new meaning! I don't have thousands for a real-time WFM, but ANYONE working with digital video NEEDS a WFM, even though most of them have never been exposed to the idea. One of your earlier posts said it well (from my memory), we gotta "see" what the levels are really doing. Eyeballing it is very nearly totally unreliable. And you said you couldn't understand why others didn't seem to need it. And I'm telling you (again) they DO need it, but are too ignorant to know it! (Granted, much video footage is okay and doesn't need black or white level adjustment, fortunately.)
I'm a programmer (more or less an obsolete ex-programmer), would like to learn C (owning Visual Studio 6), but haven't had the time to bury myself in it. And some of the things, like accessing the registry are not part of the C language itself. Most Vdub filter authors make the source a separate download. Maybe you could do that, if you haven't already. (And yes I got your kind email.) |

TC,
The source has always been out there. Perhaps I havn't pointed it out too much.
http://trevlac.us/colorCorrection/colorTools.html
That's a site I never finished. 
Also, I started to put together a guide on making a vdub filter. More basic than the filter sdk.
http://trevlac.us/vdubGuide/Overview.htm
I'd be happy to step you thru doing filters. Quite fun acutally.
Email me.

(a side note:)
I just wiggled around with the vectorscope -filter
last night. I tested it on various materials -
VHS (Original), TV, (Nth copy of a) VHS etc.
I was very curious about this filter, since I've worked
with Vectorscopes before, but this went over my
head! I had reference cards (yeah, the dull color bars)
for recordings, but they never quite settled in the
target boxes (ie noise, etc).
But your filter was not that picky and with only a
few clicks on Hue/Sat -filter, I got what I wanted.
I also took a few seconds of live feed from our TV-
station and adjusted my TV Card with your scope.
(dat wuz a lodd of wolk) And the image is much
more natural than with the "preferred" -settings!
So on a scale from 4 to 10 I give this filter a certified
11.
( from "This Is Spinal Tap!": )
"Our amps got to eleven. Yeah, the other bands get it to
ten - but ours goes to eleven."
Interviewer:
"Well, why don't you just adjust your amplifiers to play it
louder than the other bands? I mean ... you know?"
(pause)
"Our amps go to eleven."

Hey ... how did you do this? Can you get vdub to run this filter from the capture area so you can adjust the driver proc amp live? Or did you record a little, check a little, tweak the driver, record a little, check a little, etc ....
I'd love to be able to use the filter to get the proc amp adjustment without recording 1st and doing the fixes post. |

Hey TC,
I figured out how to save stuff to the registry. Now if you make changes thru the dialog box (without a cancel) they will be saved. The next time add the filter to the chain, they will be restored from the registry.
I didn't really think out what would happen if you have multiple copies of the filter at the same time, but it should work.
Batch should also work seeing that it does not use the dialog.
http://trevlac.us/colorCorrection/clrtools_1_5.rar
I did not test much, so consider it one of those greek letters.
PS: The cancel in the dialog does not work properly. Some of the values are saved (internally not to the registry) regardless if you cancel or ok.

Any progress on this filter?
In my opinion, it is impossible to do good editing without it. 
This filter should be standard build in into Virtual Dub.
The preview is the problem 
We need both the histogram and the edited picture preview... at the same time!
Trevlac,
Is it not possible to draw the histogram over the picture, transparant maybe?
Maybe others have found a solution for the preview problem?
Together with the curves filter, this filter is the MOST important of them all!
This is realy about the basics of good video editing.
Without RGB histogram... no good editing.

Is there anyway to scroll within the image of the scope? I have my monitor at 800X600 for eyesight and since my monitor is older. Would there be a way to separate the output windows into a separate window for viewing?
I have noticed something but it is more of an issue on my side:
On some of the previews with plugins, including the scope filter, the output window will jump out from Vdub and go all over the place when the sizing of the output window is adjusted. There is no other way to rid of this phenomenon when it happens, only to close Vdub and do a desktop refresh. I have checked my graphics adapter and hardware acceleration is at full. I also tried disabling/reenabling directX viewing but I get this jump out and painting issue. Is there anything I might have missed?
I can't wait to get the new computer built. I'm just waiting for the anti-static materials to arrive before I do anything. |

I know this effect...
I have the same on my old computer, too.
Are you working with high resolution files?
Adding the resizing filter at the top of the filter chain helps.
I have no problems with 720x576 files...

This computer is older than rotten cheese. It's a Comcrap pissario 5822. Intel II - 500mghz processer - max processor capable is 600mghz, 96 megs of ram - upgraded to 256, 4 meg internal video, pc-solo 16 bit sound blaster card - 24 bit card won't work, USB 2.0? what is that? Nope not on this board.
I'm going to be putting together an Intel lga775 board, Intel 3.0 ghz processor, 2 ghrz ram - might need to get an external fan since I have been reading that the fans that come with intel processors are noisy and not that great, sound card - haven't decided whether to go internal or external, video card built-in should suffice for now, better than what I probably got, lol.
When I get the new one built this will be a major upgrade for me, lol. I think I will be able to go beyond 4 fps processing 
I have an Ultrabox microfly case. Came with a 400 watt power supply and cables and has two fans for circulating air flow by default. The case can be quickly disassembled and motherboard tray slides right out. It even has its own carry handle.
What the cases look like:

I got mine for $55.00 with the rebate  |
