    Is it true that if you create horizontal motion with letters for titles that will be scanned on film you’ll have a stroboscopic/flickering effects in theater ?
    Even if you had a natural motion blur to them ?

    I’m working with shake and inferno and never heard that

    Hi,

    i have experience this type of problem on the last opening we have done. A simple title tracked on a panning wall. if the wall pan to fast the tiltle flick and some time it need to much motion blur to fix it…

    It a true problem and most of the time you cannot be sure before have seen a screen test.

    “Sorry, moving to fast do to that”

    Hi,

    The moving title amplify this effects but you have the same effect over the footage but less visible. It a issue about the frames rate. It the same as a video fielded and unfielded.

    Your eye see to much space in between movement. Generaly not a problem over a full frame but on a tiny white line is visible.

    Motion pictures is a illusion of motion with is limitation…

    So why is vertical motion okay, or at least less of a problem? Rolling credits always seem fine on film…

    Vertical motion is just as much of a problem as horizontal motion. There is a bunch of fine math involved between getting the leading, typeface height, and speed just about right. Endrollers on films often use applications presets on a specific speed vs height of characters vs leading…. I end up with the good old faithfull: Trial & error. Would seem right if someone made a little, small, tiny, back-of-the-drawer, itsy, weeny, polka-dot, bikinyee, app,….. who would help us out.,…
