    Encoding a DVDFlick project containing videos and AviSynth scripts (producing still images with subtitles), everything goes fine, except that all still images come out with a regular pattern of vertical stripes all over. Anything missing in this simple script? Or is this a DVDFlick (FFmpeg) problem?

    img = ImageSource("D:\....jpg", end=150)
    Subtitle(img, "...", x=40, y=100, last_frame=100, font="Tahoma", size=56, text_color=$FF0000, align=1, lsp=256)

    Hi.

    project containing videos
    A video source?

    This doesn't seem right.
    img = ImageSource("D:\....jpg", end=150)
    If the input is a video have a look at ImageWriter, a core filter for avisynth V2.5x
    This works for me in Virtualdub. Hit the space bar and let the video play until all the captures are done.

    avisource("video.avi")
    ConverttoRGB32()
    # centre horizontal, 270 lines down for 1000 frames
    Subtitle ("This is a subtitle", -1, 270, 0, 999)
    # capture 5 frames (150 - 154) as jpg
    ImageWriter("C:\a\", 150, 154, "jpg")




    The subtitle comes first, else the image is written without it.
    Keep adding to the script. Just get the frame numbers right.

    edit:- I usuall capture approx 25 frames. There can be small differences. Maybe a person is blinking, the wind is moving the hair, etc. It's nice to compare them side by side. A particular frame usually stands out for me.

    No, the source is a JPG, and the subtitle is missing since I clipped it to keep the upload small.
    I add these images as titles to the following videos. In the project, I have 5 or 6 of them, and they all have this artifact. The videos have no flaws.
    Thank you for your time.

    How does it look if you open the script in VirtualDub? (Thus eliminating DVDFlick from the equation.)

    Running the script in MediaPlayer (as I did before encoding) or VirtualDub, they look fine. The attached image sample is cut from the VOB file.

    Update on the story of the striped images: I had the opportunity to watch the disk on a standalone player,
    and NO stripes. They are visible only on my PC. What gives?
