Upscaling NTSC VHS to 1080p with Hybrid?

[Closecall]

Thank you for the reply so fast.

I am assuming the settings you're using are the ones for your program and not Hybrid correct?

[latreche34]

It's actually built in the capture device and are part of the proc amp after the video has been converted to digital, A link to those menu pages.

Interesting.

Also I wanted to ask when you do your video conversion down and then up for 720x480 --> 704x480 --> 1440x1080
Are you just using the normal resize or are you using the resize tool inside of AVIsynth or Vapoursynth? Could you possibly post your settings so I could see exactly what you're doing?

Thank you!

720x480 -> De-interlace -> Crop to active video area -> Upscale to 1440x1080 all in one step using multiscript avspmod frame visualizer.

AviSource("C:\Users\User\Desktop\graduation.avi")
AssumeTFF()
QTGMC(Preset="Fast")
Crop(X1, Y1, X2, Y2)
LanczosResize(1440, 1080)

So that would bring it down to 704x528 and upscale to 1440, 1080 all at once?

[latreche34]

No, Where did you come up with 528?

[Closecall]

My mistake. I meant 704x480. As you mentioned in a past post on this thread bringing it down to 704 before upscaling to 1440.

[latreche34]

You can bring it down to any resolution as long as you crop in a 704:480 ratio so you don't alter the frame's geometry, Meaning if you have to crop to 698 horizontally, 698x480/704 = 476, the new resolution will be 698x476, resize this to 1440x1080.

I also found this thread super helpful. Just had one question about cropping the video.

Example:
I need to crop all sides to get rid of the overscan...
Right: 8
Left: 8
Bottom: 8
Top: 2

This would bring the resolution to 704x470

Do you take any additional steps if you need to crop the overscan on the top and/or bottom?

[latreche34]

704x470 is a wrong aspect ratio, I don't understand your question, you've already cropped the image.

[dudebuddy]

How do you get rid of the overscan on the top and bottom while keeping the correct aspect ratio??

[traal]

AviSource("C:\Users\User\Desktop\graduation.avi")
AssumeTFF()
QTGMC(Preset="Fast")

# Crop Right=8, Top=2, Left=8, Bottom=8; result=704x470
Crop(8, 2, -8, -8)

# Center the 704x470 video in a 704x480 frame to restore the 10:11 PAR
AddBorders(0,5,0,5)

# Upscale to square pixels
LanczosResize(1440, 1080)

This adds black borders at the top and bottom in order to keep the correct PAR.

By cropping proportionally or masking off.

[dudebuddy]

What codec/file format do you export to?

Thanks for the info!

[latreche34]

Lossless HuffYUV.

Once you have the upscaled lossless avi, what application or script do you use to encode to MP4? And would you mind sharing your settings/script?

I’m using hybrid, but don’t like the results using the settings I’ve seen on this forum and others. After doing some digging, I figured out settings in hybrid that make the MP4 look pretty much identical to the lossless avi, but the encoding is taking way to long. So I’m searching and hoping I can find a way to encode a little faster while keeping the same quality.

[latreche34]

My encoding is about 5-10 frames a second, not what you are looking for.
