  • high iris

    hello
    i need help, please

    i am currently editing a video i took recently, and did not realized that i recorded it on a high iris. is there a way i can lower it down using edius? or at least repair it so it's not too high?

    thanks in advance

    If it is really blown you can bring it down but you won't recover much detail if it is really blown.

    Use the YUV curve and use a knee to bring it down.
    Make the knee at 92.

    Watch the waveform monitor when adjusting.
    Maybe you need to crush the black a little to.

          If it's really blown out and the footage is DV/HDV, then it's going to be really hard to color correct the footage. If it was 4:2:2 footage, then it'd be much easier to at least make it workable...but like Steve said, overblown footage is nearly impossible to fix, with darker footage might be a little easier to fix.

            That why there is ZEBRA in the viewFinder.
            First at 80 second at 96.
            That's how I Like it

              To get the most out of under/over exposed footage I like to use the "Screen" Key.
              I'm always surprised by this trick...

              With a clip on the Timeline...
              Ctrl+Drag the same clip to a higher track to make a copy
              Disable the upper track
              Apply Color Balance or YVU to the lower track to darken the clip
              Enable the upper track
              Apply the "Screen" Key to the upper track
              Adjust the Key Mixer Rubberbands in the upper track for effect.

              Highlights should be preserved despite darkening the original clip.

                You can allso fix the bright and contrast using Color balance filter if you need to fix overall brightnes in the picture.

                  Absolutely. If you must get it wrong it's always better to under-expose rather than over-expose.
