  1. Hi, just curious about which copy you think is better. I like both copies. The VHS video has a higher bitrate, but the digital source has better colors.

  2. The only reason the AVI has a higher bitrate is just because I saved it losslessly. I used Avidemux to make these clips in copy mode so that there's no quality loss.

  3. The AVI isn't really lossless, is it? Comes up as 480x360 resolution for one and is 50fps progressive, so seems like it was deinterlaced and downscaled from PAL? The AVI seems blockier and blurrier to me and that shouldn't be a big surprise when the digital source resolution is 576 lines vertically and the AVI is 360 lines vertically.

    The AVI is slightly brighter but has severe compression artifacts, resolution is way lower. The MPEG-2 version is darker, has full D1 resolution, has less compression artifacts. Not sure how you processed that AVI files but it doesn't look good. I would say this is comparing apples to oranges, unless you capture VHS properly with full D1 resolution and apply the same compression parameters and codec to it like the digital version, this is a useless comparison.

  5. This is the original file. I received it from a friend. I don't have any more info.

  6. The MPG file is better. It has more detail and less artifacts. The brightness/contrast is easily adjusted.

    Unfortunately that file cannot be used for comparison, Severely degraded to make a statement that it is a VHS copy.

    I tried AviSynth before but the learning curve is too much for me. There are too many dependencies. I want to know how to encode a new video with the brightness turned up (it's hard to do without messing something else up with the picture). All I have is the video from the DVD, I don't have the VHS.

  9. I'm not at my computer right now but I believe I simply used SmoothTweak(contrast=1.45). If you don't have SmoothTweak() you can use the built in Tweak(cont=1.45). Or, off the top of my head, ColorYUV(cont_y=115) should be close.

    Here's my attempt. Santiag and QTGMC helps with the jaggies on the lights. I added Camcorder Colour Denoise in VDub. I cropped and resized in VDub.

    Code:
    LWLibavVideoSource("H:\Videohelp\Shampistols\Comparison\1979.07.26 (1) Buzzcocks - Harmony In My Head 35 (OB).mp4")
    converttoyv16()
    santiag(3,3)
    QTGMC(inputtype=2)
    DeHalo_alpha(rx=2.0, ry=2.0, darkstr=1.0, brightstr=1.0, lowsens=50, highsens=50, ss=1.5) #defaults from the wiki.
