Well, VHS capturing Mostly cartoons, having some questions:)

[zerowalker]

Sorry i must ask again, i am really bad at this stuff, sorry.
But how many Watts are needed for it to work?
I tried to convert 500ma to watt or something, but we have different volt, and i don´t understand the meaning of everything,
so thought it was better to let someone who may know handle it.

Thanks

[jagabo]

Oh, I screwed up. That adpater's output is 9V DC, not AC. The polarity of the adapter doesn't matter for AC devices. Any inverter you get will be sufficient to drive a 500 mA (4.5 watts) device.

[zerowalker]

Ehm, so i could buy an Adapter instead on inverter?
Or what;S?

and 4.5 watt well, that isn´t anything;O

Well i would like the cheapest solution, but not one that doesn´t work or has been proven to be less functional. as you said something about Noise etc?

Thanks!

[sanlyn]

The amplifier device you want requires a DC input of 9v at 500ma...I forget the exact figures, but it will be printed on the chassis, and the DC adapter that comes with the amp is one designed to physically fit its input slot and deliver the correct DC power output to the amplifier. That Ac/DC adapter is a North American unit that has to be plugged into a 100v/60Hz AC power source. It's the AC power source that you are trying to match with the 220v/110v down-converter device. That down-converter will take 220v AC from your locality and convert it to 110v AC. There's no math involved. These down-converters are standard units sold all over the world.

So a circuit from start to finish would look like:

Your 220v AC power source, outputs 220v AC ->
220v/110v down-converter, outputs 110v AC ->
AC/DC adapter that comes with amplifier outputs 9v or 10v DC at proper amps ->
amplifier

[zerowalker]

Ah i see, so for example this: http://www.legoelektronik.se/index.php/ac-ac-230-110v/230v-110v-ac-45w.html

Will work?
and then the power connector that comes with the amplifier connected to that.

EDIT: wait, with no math, do you mean there is down converters that does not get you strict to a certain amount of watt?

[sanlyn]

That device outputs more than enough for small appliances like the amp, or even a VCR or laptop. Probably not enough for a hair dryer, toaster oven, or washing machine.

[jagabo]

watts = volts * amps

The distribution amp's power supply can output 0.5 amps at 9 volts. 9 * 0.5 = 4.5 watts.

[zerowalker]

Yeah good thing you told me, or both of you, as Electronics and all that stuff is extremely confusing for me;P

But i have a question, this is of to the Restoration Part.

Is there a way to apply filter, then instead of dithering to 8bit, you dither to 10bit (As 10bit encoding is available)?

[sanlyn]

With the equipment and methods available to most consumers and hobbyists, you won't see any difference. A good 10-bit PC monitor to let you see what you're doing via computer will cost you about $3000 USD.

[zerowalker]

Yeah but, encoding to 10bit got some nice advantages. And if i filter it to 8bit just to upscale it to 10bit, i thought, if i can just filter it to 10bit i won´t lose a step.

[jagabo]

You could use an 8 bit dithering filter to produce a 10 bit dither pattern by creating a black video with 8 bit dither, converting it to 10 bit, dividing it by 4, then adding the dither pattern to your 10 bit video.

[zerowalker]

That was a bit to hard for me.
Wasn´t DitherPost() supposed to have 10bit implemented to it?
Sorry.

[jagabo]

I don't know what DitherPost() does. I was just describing how you could create a 10 bit dither with an 8 bit dither filter.

[zerowalker]

I think Ditherpost() just dither to 8bit, i may be wrong, will try to read more about it, there must be a simple way as 10bit is pretty favored this days.

[zerowalker]

How can i look up what Bit Depth the current video has in Avisynth?

[zerowalker]

Ah another question, more likely to be interesting.
I i have content that is Interlaced at some places and Progressive at some (though it´s all S-video/Composite) Transfered.
What settings should i use in QTGMC for Slower?

Maybe it doesn´t matter, but worth asking

EDIT: Also, the S-video (Cheap composite separation), does anyone get the artifacts on PS2, as i get it, PAL and NTSC.

QTGMC(preset="slower")?

[zerowalker]

Does it say the bit depth?
it always say 16, so guessing it´s the audio.

Yeah of course, but was wondering, should it be like that even if it´s progressive at some times?

[jagabo]

Does it say the bit depth?

YUY2 = 8 bit Y, 8 bit U, 8 bit V
YV12 = 8 bit Y, 8 bit U, 8 bit V
RGB24 = 8 bit R, 8 bit G, 8 bit B
RGB32 = 8 bit R, 87 big G, 8 bit B, 8 bit alpha (usually dummy)

Note that the sum of the bits per channel is not the same as the average bits per pixel. YUY2 is 16 bits per pixel, YV12 12 bits per pixel, but they both encode 24 bit color. And RGB32 encodes 24 bit color. I'm not sure what AviSynth 2.6 says with 10 bit per channel formats.

it always say 16, so guessing it´s the audio.

That's the audio.

Yeah of course, but was wondering, should it be like that even if it´s progressive at some times?

You can simply double the frames in the progressive sections with ChangeFPS(). Or ConvertFPS() if you like blended frames. Or use motion interpolation if you can stand the artifacts.

src=WhateverSource()
v1 = Trim(src, 0, a).ChangeFPS(2x) #progressive section
v2 = Trim(src, a, b).QTGMC() #interlaced section
v3 = Trim(src, b, 0).ChangeFPS(2x) #progressive section
return(v1+v2+v3)

[Gavino]

I'm not sure what AviSynth 2.6 says with 10 bit per channel formats.

Avisynth itself supports only 8-bit formats. Higher bit-depth video can be handled via various utilities and plugins, but Avisynth itself will always report the bit depth as 8.
See http://avisynth.org/mediawiki/High_bit-depth_Support_with_Avisynth.

src=WhateverSource()
v1 = Trim(src, 0, a).ChangeFPS(2x) #progressive section
v2 = Trim(src, a, b).QTGMC() #interlaced section
v3 = Trim(src, b, 0).ChangeFPS(2x) #progressive section
return(v1+v2+v3)

Should be a+1 and b+1.

[jagabo]

I'm not sure what AviSynth 2.6 says with 10 bit per channel formats.

Avisynth itself supports only 8-bit formats.

Oh, I thought 10 bit support had already been added to 2.6 (I'm still using 2.5.7). Guess, not.

src=WhateverSource()
v1 = Trim(src, 0, a).ChangeFPS(2x) #progressive section
v2 = Trim(src, a, b).QTGMC() #interlaced section
v3 = Trim(src, b, 0).ChangeFPS(2x) #progressive section
return(v1+v2+v3)

Should be a+1 and b+1.

Ah, yes, It's VirtualDub that doesn't include the last frame in a range.

[zerowalker]

Yeah thought too, well hope they add it
And well i use QTGMC() and SelectEven(), so i don´t get the double framerate,
And it´s complicated as it changed alot between progressive and interlaced, so was more wondering, does it hurt the quality with QTGMC() on progressive?
Or does it sense that there is no interlace?


Thanks!

[jagabo]

QTGMC() doesn't hurt progressive frames too much. The default settings will remove a little noise and small details, and sharpen a bit.

[zerowalker]

Ah nice!
there is not any mode i should set it too?
Or any recommendations?

Thanks

[zerowalker]

What is VFW?
As if i go VFW it lags alot with my capture card, but i can change saturation and sharpness with it?
Is there anyway to fix the lag or is it some kind of filter running above that just add the sharpness or something?

When i capture it goes fine it seems;O
Though, i can´t select the audio source;S

EDIT: It was possible if i set Audio Line In as Default Device.

EDIT 2: looks like i can change shapness and Saturation etc, then change back to the original capture mode, and the settings or left

[sanlyn]

Start here:
1. Open the VirtualDub main window.
2. Press the "F1" key on your keyboard.
The Contents window will say version "1.5". Don't worry about it. Just keep reading.

[zerowalker]

So it´s some old windows device drivers?
Well it says that virtualdub can´t save restore or control thse, but i can;O
And it´s good as that is the only place i can control the other settings except Bright and Contrast


PS: Was wondering if there is some way to Force my card into supporting pal 60, as my card supports NTSC = 60hz, and PAL M which is similar to pal 60 but grayscale(i think?).

So maybe there is a way to make it go NTSC mode, but still use PAL mhz for color?

[sanlyn]

While you're adjusting Brightness and Contrast during capture, be mindful of the luma and color range limitations required by the format of your final output. It's difficult to judge by eye, if not impossible. Unless you're interested in sharpening your video's noise and then trying to clean it later, you normally wouldn't sharpen during capture. After capture there's only one way to change capture settings you didn't want and which cause processing or render problems: you have to capture again.

No.

PAL-M signals are identical to North American NTSC signals, except for the encoding of the colour carrier. Therefore PAL-M will display in monochrome with sound on an NTSC set and vice versa.
PAL-M is incompatible with 625-line based versions of PAL, because its frame rate, scan line, colour subcarrier and sound carrier specifications are different. It will therefore usually give a rolling and/or squashed monochrome picture with no sound on a native European PAL television, as do NTSC signals.

VFW might be "old", but it's still in use. VirtualDub, for example.

[jagabo]

You can use GraphEdit to adjust the video with realtime feedback in VirtualDub. Start VirtualDub's capture module. With the preview active start GraphEdit. In GraphEdit select Graph -> Insert Filter. Find the video capture device and add it. Back at the main GraphEdit window right click on the capture filter and select Properties. Go to the Proc Amp tab. As you move the sliders on the proc amp you can see the video changing in VirtualDub. You can use VirtualDub's Histrogram feature to help get the levels correct.

Windows has two video systems, the older VFW (Video For Windows), and the newer DirectShow. VFW is deprecated by Microsoft but many programs still use it.
