Capturing VHS

[amxcs]

Hello, I want to digitize my childhood VHS.
I have a Sharp VC-A30BP, a Schneider SVC200 and a Supra SV 95DK. I know they are consumer goods, but I will use one of them. I guess Sharp is better?
Video Capture - AverMedia DVD EZMaker 7
The system is PAL.

I read several threads and saw that with VitrualDub they can be digitized very well.
I watched a tutorial on YouTube I'm thinking of using this codec (Lagarith Lossless Codec) with the settings from the tutorial. Is 720x576px and YUY2 correct?

However, I want to ask if any of the other codecs are better and with what settings?

Thanks!

I have the Avermedia EZ maker 7 as well and will say that it works better than the Hauppauge USB Live-2.

I'm in the same boat as you and ended up capturing in AmarecTV using Lagarith to a lossless avi 720x480 . Deinterlacing and noise removal via QTGMC commands in avisynth+ run through virtual dub 2, resizing to 640x480 and then final encoding in handbrake H264 (no resizing, no noise reduction) at a healthy file bitrate size and slowest encoding you can stand.

I would recommend capturing to a SSD or even better NVMe, or you risk studder.

capturing and/or deinterlacing in virtualdub2 was noticeably worse picture quality to me.

Is that beacuse tha audio glitches you reported recently with the USB-Live 2?

[Forenzik]

Yes, either I just happened to get two bad devices direct from Hauppauge or they have a widespread manufacturing issue. Even it on different machines with the same result. Since I'm not seeing any difference in video quality, my vote goes to avermedia.

[lollo]

Ok thanks

Deinterlacing and noise removal via QTGMC commands in avisynth+ run through virtual dub 2, resizing to 640x480

Capture all tapes in lossless quality.
Now it should be deinterlaced. Can you have a guide or a video tutorial on how to do it?

[amxcs]

I saw this tutorial.
Which script should I use for deinterlacing and noise reduction?
Is the one from the tutorial enough?

SetFilterMTMode ("QTGMC", 2)
FFMPEGSource2("videofile.avi", atrack=1)
AssumeBFF()
QTGMC(preset="Slower")
BilinearResize(720,540)
Prefetch(10)

[lollo]

Post a sample of your capture...

[Bwaak]

I saw this tutorial.
Which script should I use for deinterlacing and noise reduction?
Is the one from the tutorial enough? Или той е само за деинтерлейсинг?

SetFilterMTMode ("QTGMC", 2)
FFMPEGSource2("videofile.avi", atrack=1)
AssumeBFF()
QTGMC(preset="Slower")
BilinearResize(720,540)
Prefetch(10)

Why MPEG2 is BFF? Why bilinear? Why 720x540? What is your target platform?

[amxcs]

VirtualDub 1.10.4
Lagarith Lossless Codec with YUY2 mode
Format 720x576px and YUY2
Audio 44.10khz, 16bit

Your capture suffers of "flagging(tearing)". You need a TBC correction, if you can't have a high-end S-VHS machine with T.B.C, add a DVD-Recorder in pass-through mode, such as Panasonic ES_10 or ES-15:

it also suffers of "crushed" blacks, try to tune the procamp of your card:



Here a restoration attempt using classics approach

AssumeTFF().QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1)
TemporalDegrain2(degrainTR=3)
LSFmod(defaults="slow")

and compressed to h264 for size reduction: rest.mp4

Some of the frames with lines dropout (defect on tape) can be replaced with interpolated frames.

In your original script AssumeBFF() is wrong, and BilinearResize(720,540) is useless and lossy

[amxcs]

Wow, I didn't expect it to turn out so well! It is wonderful!

However, I will also try to find a high-end S-VHS machine with T.B.C.

How do I tune the procamp and how do I know it's good?


Is the script that good?

    SetFilterMTMode ("QTGMC", 2)
    FFMPEGSource2("sample.avi", atrack=1)
    AssumeTFF().QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1)
    TemporalDegrain2(degrainTR=3)
    LSFmod(defaults="slow")
    QTGMC(preset="Slower")
    Prefetch(12)
    Crop(10,0,-6,570)

Is it ok to use Crop(10,0,-6,570) to crop the unnecessary?

And finally to ask what settings to use for encoding. Is it ok in .MKV?

[lollo]

This is the sample.avs script I used:

video_org=FFmpegSource2("sample.avi", atrack=-1) # no Lagarith installed

# cropping 
	crop_left=8	# | rimozione esatta delle bande nere sinistra, sopra, destra e del disturbo sotto	
	crop_top=2	# | 720-(8+8)x576-(2+10)=704x564
	crop_right=8
	crop_bottom=10
video_org_crop=video_org.crop(crop_left,crop_top,-crop_right,-crop_bottom)

### deinterlacing
deinterlaced=video_org_crop.AssumeTFF().QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1)

### convert to YV16
deinterlaced_yv16=deinterlaced.convertToYV16()

### denoising
denoised_yv16=deinterlaced_yv16.TemporalDegrain2(degrainTR=3)

### convert to YUY2
denoised=denoised_yv16.convertToYUY2()

## convert to YV12
denoised_yv12=denoised.convertToYV12()

### sharpening
sharpened_yv12=denoised_yv12.LSFmod(defaults="slow")

### convert to YUY2 with chroma from YUY2 color space
sharpened=sharpened_yv12.convertToYUY2().MergeChroma(denoised)

### add borders
video_rest=sharpened.addborders((crop_left+crop_right)/2,(crop_top+crop_bottom)/2,(crop_left+crop_right)/2,(crop_top+crop_bottom)/2)

return(video_rest)

If you want to crop, then specify the PAR (Pixel Aspect Ratio) in the final encoding rather than the DAR. Search the forum for details.

For encoding I used a simple command line:

ffmpeg.exe -i sample.avs -c:v libx264 -crf 17 -preset slow -aspect 4:3 -c:a aac -b:a 128k sample.mp4

If you prefere the Vdub GUI is ok (choose your preferred CRF).

Do not capture with VirtualDub 1.10.4 but 1.9.11 or, better, with AmarecTV.

Do not capture audioat 44.1KHz, but 48KHz.

Improve your hardware to remove the flagging!

[amxcs]

Thanks!
This is exactly what I needed for a newbie like me, just changing the file name.
I also tried AmarecTV, it gave me 2 errors on launch, then loaded, I looked at the program, but there were too many options that I don't know what to do, and then I found a tutorial on VirtualDub.

[lollo]

AmarecTV guide: https://www.digitalfaq.com/forum/video-capture/12986-amarectv-virtualdub-inserts.html

[amxcs]

Ok, I'll try amartecTV too.

For encoding I used a simple command line:

ffmpeg.exe -i sample.avs -c:v libx264 -crf 17 -preset slow -aspect 4:3 -c:a aac -b:a 128k sample.mp4

And is it normal to convert a 2 minute video to "half an hour"?

[lollo]

That’s because AviSynth processing time, not ffmpeg

My more-pictorial AmarecTV guide here.

[Forenzik]

Is there any way to get multi threading to work in this script? I notice that it's only hitting the cpu at like 12%, with a rendering rate of 3fps.

I assume no because TemporalDesnoise 2 doesnt work with a SetFilterMTMode() command?

[wcndave2]

My more-pictorial AmarecTV guide here.

I can't get the huffy codec to show, even when install has been selected on the inf file and after a reboot.

Secondly, I tried a very similar process, and after running the script via ffmpeg or vdub2, the audio was delayed by about 5 seconds.

SetFilterMTMode("QTGMC",2)
FFmpegSource2("test-25-i.avi", atrack=-1)
AssumeTFF()
QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1)
BilinearResize(768,576)
Prefetch(20)

Any idea why that might be?
Thanks!

[amxcs]

Try 32bit version.

[wcndave2]

Try 32bit version.

That was the first thing I did after a reboot and there were no results.
I get the same thing

@wcndave2, yes, unfortunately getting HUFF onto your machine isn't easy. Have a read of this:

https://github.com/hofmand/video-codec-installers

That should get you going.

32 bit version msi was the option that worked, thanks!

This worked for me (32bit) - https://github.com/hofmand/video-codec-installers/releases
