"Upgrading" dvd video for Youtube upload

[Bencuri]

Youtube always degrades my SD videos, so I am converting the one attached to make it look better when I upload it. Can you do any more for this than the "upgrades" in the script? I don't want to make it look pristine just trying to upgrade it to make it more conform to our times.

LWLibavVideoSource("zaikom.mpg", cache=false, prefer_hw=2) 


QTGMC()
ColorMatrix(mode="rec.601->rec.709", clamp=0)

Dehalo_alpha(rx=2.0, ry=1.0, darkstr=2.0, brightstr=2.0)
SMDegrain(thsad=75, tr=2, prefilter=4)

nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=960, fheight=720)
aWarpSharp2(depth=5)
CAS(0.5)

nnedi3_rpow2(2, cshift="Spline36Resize")
CropResize(1920,1080, 20,8,-10,-6, CropDAR=4.0/3.0, Resizer="Resize8", Borders=true)
aWarpSharp2(depth=5)

If your frame size is at least 1152 high, Youtube will encode your video into VP9 as opposed to the usual H264/AVC.

If your frame size is at least 1536x1152, Youtube will encode your video into VP9 as opposed to the usual H264/AVC.

I know one more option. But what will happen to the details? H.264 is the other one but when you upload MPEG-2 to Youtube, no matter that it becomes H.264, the video becomes blurry if it is not a decent quality one.

Assuming you're talking about a PAL DVD, de-interlace it to 50p using QTGMC, then upscale to 1536x1152 for 4:3 or 2048x1152 for 16:9, and preferably keep it in some lossless format like Lagarith, Huffyuv, or UT.
