    Jpeg is ‘shimmering’ when panned…? Please help.

    Posted by Paul Collins on October 14, 2009 at 7:01 pm

    Hello all!

    I know I have read about this problem somewhere before but I just cant find the answer anywhere.

    I have a jpeg which I am using in a video project but am getting some nasty effects when panning from top to bottom of image,

    The effect is sort of like a ‘heat-haze’ or ‘shimmer’ that can be seen in areas of details.

    Now I have tried to reduct this by resizing the jpeg down by 50% and have even applied a very slight Gaussian Blur of 0.2 to try and melt those detailed sections but no matter what I try I am still getting this horrible effect that is completely spoiling my work.

    Unsure if it is of use but I am using a frame server to serve TmpgEnc for the encode. Premiere CS3 keyframe and rendering is set to ‘Lower Field First’ and with optimize still ticked.checked. The frame server sends it all to TmpgEnc which is encoding to progressive video file.

    I dont think the problem lies with progressive or interlaced settings – I think it is purely a problem with detail in the jpeg, but if anyone knows how to remedy this or improve the output then I would be so so so appreciative.

    I hope I have explained this well and look forward to any help whatsoever.

    Thanks in advance.

    Paul Collins.

    Previewing images at less than actual pixels can be misleading…in Photoshop, Premiere or any other app. Suggest set zoom level of the Program window to 100%. If there is still an issue, right click on the Jpeg in the timeline and choose Field Options> Flicker Removal.

    Thanks alot Mike.
    The flicker is still there and I have used the remove flicker option in the field options for the still image.
    Cheers.

    it sounds like the pixel size of the JPG is likely much larger than your video frame size…correct ? I’d try reducing the size of the JPG to something no more than 2x the vido frame size in width and if that alone isn’t enough, possibly run a slight blur on it in photoshop (VERY slight)
