    Auto Color Effect flickers off and on

    Dwilson407

      I have just tried using auto color under the video adjust effects and the effect seems to flicker off and on in all of my clips. Anyone else had this problem

      or is it my computer? I have a new computer with 12 GB of RAM.

      Thanks

          Doug,

           

          This is the rub on almost all of the "Auto" Effects. Unless the scene is absolutely constant in lighting, and needing the same exact correction, one gets a "pulsing," "strobing" or "flicker."

           

          I strongly recommend using the Fast Color Corrector (or one of the other non-Auto Effects). Same for Auto Levels, etc.

           

          Good luck,

            I think that explains it. Thanks a lot!!

              To be useful, the scene needs to be so very consistent, that then one probably does not need any Effects, Auto, or not. I am sure that there are some uses for the Auto Effects, but I have just never seen them. At least with Auto adjustments in PS, there are some very particular instances, where they do actually work well, but very few.

               

              Good luck,

                The trick would be using "auto" to find the look you like (on a particular frame), and then applying it across the clip.  This is actually what I was looking for when I found this thread.  I assume there is a way and hope that I can find it quickly! (just doing super-rough looks so the client isn't looking at desaturated ("boring") footage when checking dailies --but would prefer to not have the flicker of "auto" because it looks like a problem with the lighting/iris)

                  Did you just drop the effect on the clip or did you set Temporal Smoothing as wel?

                    I saw the settings for Temporal Smoothing, but they didn't seem to have any effect.  I assumed they would prevent "hard swtiching" between different levels over the timeline, but the flicker did not appear to change with Temporal Smoothing selected (and/or adjusted).  Perhaps I am just not using it correctly, but as it didn't seem to have any effect, I stopped messing with it.

                     

                    I have currently gone back to my usual method for quick looks color/contrast adjustment, which is simply setting levels with the "Levels" effect and picking from one of several previously created presets.

                      Hey,

                      I'm getting that same sort of flicker from using fast colour correction. I can get so far and everything is working well, then it all goes flicker! I think i've got more than enough computing grunt but I'm a very nerw user of Adobe Premiere Pro (two weeks in) so it might be a school-boy error. Any ideas?

                       

                      Thanks
