Capturing S-vhs tapes using VirtualDub correctly - advice needed.

[Sharc]

Can I use Histogram whilst capturing in AmaRecTV ?

See here:
https://forum.videohelp.com/threads/401225-Histogram-for-Amarec-TV#post2614699

Example (capturing the menu of the ES15) with the histogram in real time, using
-MPC-HC
-Avisynth
-GraphStudioNext
-AmarecTV
(The capture device is GV USB2, similar should work with the USB-Live2. Instead of the histogram one can show the waveform monitor on the side or on top)

I get an error.

Copy again the code, I fixed a typo while writing, sorry

This time it crashed when I press F5 on avsPmod. Tried opening saved script on vdub and it crashed there too.

Maybe too heavy for your system. SPlit the processing in 3 parts. First file just stop after deinterlacing, create a HuffYUV output. Use this file as input fo rthe second script, where only denoising is present, and so on...

nah avsPmod just closes after f5 same with vdub aswel.

ignore last post, script is running now in vdub2...getting 6fps render rate. Thanks lollo.

Well, that's slow. If you split the script it will run much faster, but you need to generate intermediate (big) files

sure I give that a go, thanks. most videos I need to transfer are almost 2hrs in length at this rate they all take 10hrs roughly lol.

[Akuma786]

sorry correction, script only runs when i remove this line :

### de-interlacing
deinterlaced=video_org_crop.AssumeTFF().QTGMC(pres et="slow", matchpreset="slow", matchpreset2="slow", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1)

[lollo]

there is a spece in the word preset between s and e, I do not know if it's a bad cut and paste or a typo.

Try debug with a simple QTGMC() instead

[Akuma786]

Yeah still having issues with the script wont load. I'll revisit this thread after a week, wont have access to my computer until then. Thanks guys for all your help.

[rgr]

I can't confirm.
Quite the opposite -- VirtualDub performs better than AmarecTV.

Sharc, what's your code for ProcAmp_GV-USB2.avs?

Sharc, what's your code for ProcAmp_GV-USB2.avs?

Here we go:

DirectShowSource("GV-USB2.grf",audio=false,framecount=15000) 
converttoYV16(interlaced=true) #convert to planar

## uncomment one of the 4 options below as needed:
Histogram("levels")     # Histogram on the side
#Histogram("classic")   # vertical Waveform Monitor on the side
#TurnRight().Histogram("classic").TurnLeft()   # horizontal Waveform Monitor at the top of the frame
#Histogram("color2")    #Vectorscope

ConvertToRGB32(matrix="rec601")

Thanks Sharc. Found LAV Video decoder on VH download site.

[Alwyn]

Nah, couldn't crack it: "cannot render file" or error messages when trying to connect pins. Everything looks exactly like yours. What exact MPC version and bitness are you using?

All 32bit. MPC-HC 2.3.6 portable, Lav Filters 0.79.2.20

Try this filter graph. Opens here in Vdub32 and Vdub64.

P.S. You cannot run AmarecTV at the same time. This procedure is for real-time proc-amp adjustments only. Once the settings are done, save, close all this and start AmarecTV for capturing as usual. It will use those procamp settings.

Hi, So I'm trying to get the script to run, as suggested broken it up into 3 bits.

First part - Deinterlace:

AviSource("E:\Capture Files RAW\Tayyaba birthday.avi")converttoyv12()

# cropping 
crop_left=8	# | rimozione esatta delle bande nere sinistra, sopra, destra e del disturbo sotto	
	crop_top=0 # | 720-(8+12)x576-(2+8)=700x566
	crop_right=12
	crop_bottom=8
crop(crop_left,crop_top,-crop_right,-crop_bottom)

### de-interlacing
AssumeTFF()
QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1)
convertToYV16()

prefetch(24)

So this script wouldn't run at first. I had to add converttoyv12() at end of line 1 for script to work and then in crop section I had to change crop top to 0 from 2, otherwise I was getting an error ( YUV420 height must be multiple of 4). Just want to double check is this all correct now for me to proceed.

[rgr]

You don't have to reduce the top crop from 2 to 0, you can increase the bottom crop from 8 to 10 (or to 6).
And I don't know why you change the format to YUV420 from probably YUV422 at the beginning -- this is a mistake.

I don't know too, without the added (converttoyv12) in line 1, the script just ends up closing the AvsPmod after pressing F5. I cant seem to find any other way round it. Please let me know if there is any other way round this. Thanks

[rgr]

Use VirtualDub to edit the AviSynth script -- it's convenient.
After AviSource line type Info ( http://avisynth.nl/index.php/Info ) and paste the screenshot (remove the rest of the script)

[Akuma786]

and paste the screenshot (remove the rest of the script)

I don't understand what you mean by this. What screenshot are you referring too ?

[rgr]

http://avisynth.nl/index.php/Info
Gives clip property information as a text overlay in the upper-left corner.
You should have YUY2 and stick with it.

[Akuma786]

Got it Thanks, rgr. So in info it showing as Bottom field first but in my script I have AssumeTFF. Do I need to change this ?
See screenshot:

[rgr]

Change it to AssumeBFF and after a few frames you will see what setting is correct

[Akuma786]

Okay so I've made some progress with the script, It's almost running but I have to delete last two lines:

.MergeChroma(upscaled)

return(sharpened)

The above two lines I must delete from script and only then video loads in VDub2. If I include them two lines I get error messages.


Error message i get are:
1st error - It doesnt know what upscaled means - so i delete (upscaled) from script and then the next error message i get is - Invalid arguments to function 'MergeChroma'. Then I delete MergeChroma from script and error i get is - I dont know what 'sharpened' means. So I delete that too and I get syntax error and have to delete return() from script and then the video loads.

I guess I need them last two lines to get same output quality as lollo's sample. Can anyone help me out please.

Here is the script I have working:

AVISource("E:\Capture Files RAW\Zishan Birthday.avi")

# cropping 
	crop_left=8	# | rimozione esatta delle bande nere sinistra, sopra, destra e del disturbo sotto	
	crop_top=2	# | 720-(8+12)x576-(2+8)=700x566
	crop_right=12
	crop_bottom=8
crop(crop_left,crop_top,-crop_right,-crop_bottom)

### de-interlacing
AssumeTFF()
QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1)
convertToYV16()

### denoising
TemporalDegrain2(degrainTR=3)
### convert to YUY2
convertToYUY2()

### change color matrix
Colormatrix("Rec.601->Rec.709")

### add borders
addborders((crop_left+crop_right)/2,(crop_top+crop_bottom)/2,(crop_left+crop_right)/2,(crop_top+crop_bottom)/2)

### upscale
nnedi3_rpow2(rfactor=2, nns=4, qual=2, cshift="Spline36Resize", fwidth=1440, fheight=1080)

### convert to YV12
convertToYV12()
### sharpening
LSFmod(defaults="slow")
### convert to YUY2 with chroma from YUY2 color space

convertToYUY2()



prefetch(24)

Also the strange thing is the script wont open anywhere for me unless I add : convertToYV16() end of first line. Without this it doesn't open. Once open, then in vdub2 I can edit the script and remove 'convertToYV16()' and it will work if you know what I mean.

There is no point in the recent conversion to YUV422 since you previously degraded the quality by converting to YUV420. Replace lsfmod with lsfplus and throw away the conversions.

Sorry my knowledge of Avisnyth is beginners level, I don't know what you mean by I degraded the quality by converting to YUV420. All I would like is to use the script lollo provided to work on my computer, so I can get the same exact final output from my captured avi. I have kept the script exactly the same I think and its just the last 2 lines of the script I like to get working without errors.

[Sharc]

Sorry my knowledge of Avisnyth is beginners level, ....

It is always problematic when users just copy scripts, not understanding its implications.
Anyway, you may want to try this simplified version to begin with which should avoid your conversion conflicts:

AVISource("Zishan Birthday.avi")
assumeTFF()
QTGMC()
crop(8,2,-12,-8)
Colormatrix("Rec.601->Rec.709")
addborders(2,4,2,6)
nnedi3_rpow2(rfactor=2, nns=4, qual=2, cshift="Spline36Resize", fwidth=1440, fheight=1080)

[rgr]

A line with Temporaldegrain2 is missing.

Intentional. As I wrote: Simplifying (and speeding up) the script. Avoiding his conversion issues shedding unnecessary burden in a first step. The source isn't even very noisy or grainy, and QTGMC() already denoises. Personally I don't strive for overdenoised plastic skins of "natural" videos. But here we go:

AVISource("Zishan Birthday.avi")
assumeTFF()
QTGMC()
crop(8,2,-12,-8)
Colormatrix("Rec.601->Rec.709")
ConverttoYV16().Temporaldegrain2()
addborders(2,4,2,6)
nnedi3_rpow2(rfactor=2, nns=4, qual=2, cshift="Spline36Resize", fwidth=1440, fheight=1080)
#cas(1.0)   #enable for sharpening

Hi Sharc, I tried your script, it doesnt load on AvsPmod when pressing F5, just shuts down the software. Again to make video open in AvsPmod, I must add 'ConvertToYV16' end of line 1, only then it opens. I cant figure out why though. I tried googling it.
