  • Rendering of VisTitle clips results in clips without alpha!

    As the topic says rendereing Vis-titles loose any alpha informations!

    steps to reproduce:

    1. create a VisTitle still clip on timeline in front of a background track
    2. close vistitle
    3. right mouse click on title-clip item --> render
    4. test the result

    The resulting clip will be layed over the background track and just only a black background with a title ion front will be showed!

    Hi Andreas,
    Yes you are correct. Following your steps ends up with the title on a black background. However why use the render step, when there is no need. If you eliminate that render step the title displays perfectly.

      Importing subtitles (average 10 per minute) ends up with 900 titles on a 90 minutes timeline!
      Rendering improves the stability & speed of EDIUS!
      Try to work with 900 titles & you would like to render as me! ;)
      I really have no problems with a normal rate of titles in a clip!

        Andreas,

        This has always been the case shift +g render does not carry alpha with anything.(try it with a title created in quicktitler)

        To use the render use either Shift+ Q (this adds a clip above) or
        put and in out and press shift + alt +Q (this does a render without the add)
        So as you can see there are 3 different methods of rendering. Just note the difference :)

        The clip render shift + g is usefull for effects and trasitions.
        The great thing is that even if you move the clip the render follows it. The bad thing is it does not respect the alpha.

          Hi Steve,

          THX for your suggestions!
          It doesn't help for my needs!

          I just want to render the subtitle clips (with alpha)! ;)
          I accept this limitation is set by EDIUS, not by VisTitle!
          Hopefully this will change in future!

            Are you saying that even if you mark in and out on that title and do a shift+q, it lost the alpha? if so that is not right. E5.52 and TM doesn't do that.

              NO if you read again that is not the case SHIFT +G does that

                Yeah I kind of figured that, I was asking Andreas to make sure that he did use Shift+q, don't understand why he said it didn't help.

                  Ahh sorry .... let's have Andreas explain. :)
                  Both other methods indeed obey alpha.

                    In timeline windows, "shift + G" render the title clips without alpha, it is limited by EDIUS.

                    But, there is a way to render title clips to a HQ avi file with alpha. See attached screen-shoot pictures which indicates how to do this, hope it can help you.

                      Thank you Khoi & thank you Steve for trying to help me.
                      Shift+q renders the complete timeline or (if marked) the IN & OUT area without alpha and adds a new clip above.
                      Thats not what I need. I want still editing in timeline!

                      Since a bulk of VisTitle clips (around 900) will sluggish the editing workflow in EDIUS
                      I just want to pre-render the subtitle clips only to speed up the my work in EDIUS.

                        Thank you, this could be a way to help.
                        Will test this on my workstation in the office tomorrow!
