    Recently when i've been trying to render often long files, after rendering maybe 20 minutes or an hour at most, the rendering just stops dead in it's tracks and doesn't do anymore. Has my processor had it? It's an i7 6700k

  2. check your temps during load

    what files ? Details about the input file

    What vdub input driver ?

    What filters if any ?

    what rendering / what encoder ? What settings ?

    "FFmpeg and Virtualdub keeps freezing during rendering" - what do you mean by ffmpeg ? How is ffmpeg involved ? Are you using external encoder feature with ffmpeg ?

  3. If both VirtualDub and ffmpeg are freezing while encoding it may be that your CPU is overheating. Check CPU temps while encoding. If it's overheating make sure your CPU cooler's fan is still working and that the cooler isn't caked with dust.

    ffmpeg64 to be precise, i use it in a batch file to render from an AVS file.

    Code:
    ffmpeg64 -i "Video.avs" -c:v libx264 -channel_layout stereo -b:a 320k -crf 20 -preset Slower -bf 2 -profile:v high -movflags +faststart Output.mp4
    Code:
    SetFilterMTMode("DEFAULT_MT_MODE", 2)
    SetFilterMTMode("QTGMC", 2)
    AVISource("I:\VHS Captures\Tape 1.avi")
    AssumeTFF()
    QTGMC(preset="slower", matchpreset="slower", matchpreset2="slower", sourcematch=3, tr1=2, tr2=1, NoiseTR=2, sharpness=0.1, border=true)
    ConvertToYV12()
    nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=768, fheight=576)
    Crop(4,2,-6,-6)
    aWarpSharp2(depth=5)
    unsharp()
    SMDegrain(tr=1,thSAD=1000)
    ColorMatrix(mode="Rec.601->Rec.709")
    Prefetch(10)
    I did try turning the MT options off, but to no avail.

    Good point. I'll take a look and see if it's still running. Whilst monitoring Core Temp, the cores are gradually rising to over 90 Celsius.

    Probably is a good time to give the inside of my PC a good blow, it's been a while. Once i figure out where i've put my air blower!

  5. So the script is the common factor between ffmpeg encoding, and separately vdub hanging ?


    A common culprit of QTGMC script hanging is an old avstp.dll version. Check to see if you have at least v.1.0.4.1

    https://github.com/pinterf/AVSTP/releases


    Not related to the hanging, but ConvertToYV12() should be ConvertToYV12(interlaced=true)

    I tried that but to no avail. I hadn't updated QTGMC for a couple of years by the looks of it, but didn't help either.

    Well having looked inside, the CPU cooler fan is in full working order. And doesn't appear to be an overly amount of dust inside. Unless the cooler has sucked alot in i cant see.

  7. CPU temps in the 90s is in/near the danger zone, depending on what CPU you have. Overheating is likely your problem.

  8. Are you using the older version of virtualdub or the newest virtualdub2 by volt? https://www.videohelp.com/software/VirtualDub2
    I've had issues with older virtualdub that virtualdub2 doesn't seem to cause me to happen.
    Maybe it might make a difference for you being newer and more updated than the past one.

    Might need to apply new paste to the cpu cooler or get a better cpu cooler.

    Good thinking. It's been in there since 2018 without any new paste applied, so that's most likely the problem! I forgot it had paste on it, but it's been so long since i built this PC. Will the tube of thermal paste i have from then still be fine to use now or will i need to buy a new tube?

    Also my cpu cooler is the Cooler Master Hyper 212X. So i'll upgrade if this doesn't work.

    Yeah virtualdub2 is what i use. More than likely an overheating issue though.
