I just heard about ffdshow and how it has gotten quite a following. I am currently using a 1.3 Ghz machine for a htpc. It seems clear that this is not enough horsepower to use ffdshow. However, I still would like to see the results or even hear about them. I am now trying to see if building a new htpc with max power is worth the cost just to run ffdshow properly. Does anyone have any screenshots to display what ffdshow looks like in comparison to the standard filters?
ffdshow comparison screenshots??

The best way I can explain it is this. After testing it for a few minutes it was immediately noticed by my wife as she said (while I was testing Star Wars 2) and I quote “Wow it looks like I can walk into itâ€
Now I don’t know about most of you but my wife has never said anything about the PQ, NEVER, other that the first day we go the TV. She couldn’t tell the difference from a non progressive DVD player to an HDTV LOL (Until now)
Now onto what I think
First it gives a nice sharpening to the picture while not making it look edgy or noisy. (Basically it gives a nice POP to the picture without all the bad side effects that usually come with it) I also noticed that it seemed to give depth to the picture that wasn’t there before creating that walk it the picture look my wife was talking about.
Now on to how I'm using
I use ffdshow with the NvDVD filters with the Resize ( set to 1440 x 960 ) and the luma and chroma sharpening set to 1.30 ( I find anything above that to make it look to sharpened. ) then I use the ffdshows ( not DScalers ) Gradual denoise set to 40. That filter is used after I resize the picture.
My system is an 1800 Athlon with 512 PC2700 ram and it is maxed running at about 90 ~ 98 % but with no dropped frames

I apologize for my ignorance but this ffdshow still confuses me. You say it does a resize...does this mean that people with digital projectors cannot take advantage of it since our resolution must match that of our digital projector's native panel resolution?

Thanks Owen. However, I am still confused about the digital projector issue. I am quite sure that if I use a resolution any different than my native panel resolution on my projector the resulting image will suffer. Is this partly what ffdshow does or is something else going on here? Anyone out there using ffdshow with a digital projector?
JP:
The resize filter does not affect your outputting resolution. So whatever custom resolution you set for you projector in powerstrip will remain.
The trick is this ---
You are up scaling the video signal to a much higher resolution such as 1440 x 960 then you are sharpening the video at that resolution which allows a much finer sharpening, do to the increased resolution. Then you are removing any noise, at the much higher resolution and when ffdshow is done, it sends the signal to you video card, which then downsizes the resolution to the one you have set in powerstrip.

Some screenshots would be appreciated. It would be great to see if what I've been spending all of my (very limited) free time on is going to be worth it. 
I can host them if anyone wants to take some captures. That way they could be bigger than the forum allows.
Edit: if anyone wants to take me up on the offer, e-mail the images to [email protected]

Could someone explain what programs to use with ffdshow? I've tried finding a demo of theatertek with no luck, but is there any other program that I can use instead?

I find that using ffdshow without resize just creates a noisy and edgy picture when compared to ffdshow with resize. The thing I would try first is to change the resize from bicubic to experimental, then if that doesn’t help, move the noise reduction up above the resize and last but not least turn off the noise reduction.

I find it funny you should say that, considering that I'm using ffdshow set to 1440 x 960 on a system with an Athlon 1800 ( 1.53 GHz )
Didn't you say you had a thunderbird overclocked to 1.5 GHz??
Have you even tried it??
You could very easily upgrade to something similar for about the cost of three dvd's ~60 bucks

| Originally posted by Goi Well, that's all fine and good, but the thing about resize is that its extremely CPU intensive. Unless you have a 2+GHz machine, you pretty much can't do resize. |

yes, but I have as yet to here of anyone on this forum being able to push past 1440 x 960 with any CPU even the 3 GHz p4
| Originally posted by Skipper Is there a bigger gain if you resize to an even higher res before sharpening?? And if so. Aren't the PQ then limited to the size of our.......cpu's Just a thourght Skipper |
