MSU Smart Brightness & Contrast Filter released The most professional free Brightness & Contrast! Main features * The filter doesn't shine bright areas, and doesn't move dark areas to 0 brightness value, keeping details in them * Automatic brightness tuning mode, when contrast is set (useful for long mixed films). * Automatic brightness & contrast adjust mode (useful for long mixed professionally created films). * Color correction feature - usable for hard contrast correction of nearly black-and-white movies. * Adjustable intraframe contrast & brightness accuracy. * Controllable noise influence in final parameters in automatic parameters calculation. * Careful intrascene modification of parameters * Automatic detection of scene replacement (use to prevent brightness flicking during one scene) * Supports VirtualDub Job Control and AviSynth * Already speed up! http://compression.ru/video/smart_contrast/index_en.html Enjoy!

QUOTE LoadVirtualDubPlugin("...Virtual Dub\plugins\MSU_SmartBrightness.vdf","MSUSmartBrightness", 0)  clip=AVISource("D:\Video\Samples\MSU.avi", false, "RGB24") clip.ConvertToRGB32.MSUSmartBrightness(0, 150, 100, 0) So, this filter as well as some other MSU-filters (SmartSharpen, MSU Denoising, etc. - correct me, if i'm wrong) seem to require RGB-colorspace. On the other hand, both AviSynth and VDub (1.6.x) can handle YUV-colorspace... So, my question is: Does MSU have any plans to release native YUV-versions of these filters? ... of new ones? PS: MSU = Moscow State Univercity?

Nupodgi: filtering in VDub is still done in RGB32

QUOTE (stephanV @ Feb 17 2005, 03:17 AM) filtering in VDub is still done in RGB32 what for? actually, i see no reason... just to keep a compatibility with the old VDub filters? is there any other reason? anyway, operating in YUV-colorspace seems faster (RGB24 -> 24bits, YUY2 -> 16bits, YV12 -> 12bits) and, at least, AviSynth-version (i personally use mostly AviSynth-filtering) could be optimized for processing speed. Pro: much faster, do not need to convert YUV->RGB->Filter->YUV Contra: it might require to change a filtering algorithm (since it's probably based on the RGB-component processing)

QUOTE what for? actually, i see no reason... just to keep a compatibility with the old VDub filters? is there any other reason? Re-writing the filtering part requires work (and probably a lot of work), and phaeron seems to be more focussed on DS capturing now. So maybe in a later stage.

vdub would greatly profit (speed and variety of filters) from an option to natively load avs filters and do processing in yuv. putting avs filters to vdub filters dir, filters show up, and you enter parameters by hand (ie copy/paste them from existing avs scripts... ). this would probably require porting avs core to vdub, so avery won't be doing it.

I will try this filter right away. I have used Autolevel for old 8mm film but it sufferes from a blue cast sometimes. Keep the good work going. My next question is when the "Old Film Recovery Filter" is going to be released? richard photorecall.net

DmitriyV..............what have you done. I have been looking for a replacement for "AutoLevel", the one that was upgraded from the old " ADC See" plug-in. The problem that with "Autolevel" is the blue cast it adds to some scenes. Also it must be the first filter in the chain or it doesn't work. I have a project which contains 36 reels of the worst film I have ever digitized. If fact the folder is called BAD FILM. So here's the chance to see what your new free auto brightness-contrast plug-in would do. By it's self I was impressed with the control of the plugin, no artifacts were notice. However it did not have a white balance so what I did was to place the ADC See in second position. CRASH! CRASH! CRASH! MSU memory out abounds. So I just processed the clip with MSU alone first. Then again with "ADC See" and three other plug-ins. The results were fantastic, infact too sharp, but I redid it, and it was great. There was some blue casting but a good trade off. I had another project not as bad but really could use some help. On this workstation there no crashes but the "ADC See" combo did not give the results, plus there was a blue cast to some parts which made it unaceptable. I ended up making a Russian samwitch, two MSUs for bread and one ColorMill 2.1 for cheese. This yielded a great restoation using color mill for white balance and it's ability to remove yellow tinge from highlites. Thanks so much for this plug-in. richard photorecall.net
