  • Credit Roll: How to make the credits transparent so they play over video

    Posted by Alex Keppler on September 29, 2009 at 2:43 am


    I need to credit a credit scroll. The plug-in for vegas works great. I previously did it fine using credits over a video playing in the background. Problem is I need to re-do it and can’t for the life of me remember how I did it the first time.

    Also i know I could just put the credit roll on a track above the video and adjust the tranparency but then the credits themselves still have a black background so the video is darkened. I want the background to the credits to be completely transparent so the video plays as it normally would.

    Thanks in advance,

    You will have to re-render your credit rolls as ALPHA CHANNELS. This will give you the transparent background you’re looking for. There are only certain formats that support alpha channel…. uncompressed avi being one of them (which is what I use). It’s probably the most generic approach and will import to just about any NLE.

    Render your credit rolls as uncompressed avi (you’ll need a lot of disk space) and you will see an option for alpha channel render.

    Import this to vegas…. but you will have to TELL vegas that it’s an alpha channel. You can do this by right clicking the clip while it’s in the project media window. In the properties box you will see an alpha channel option box.

    Try Media Generators -> Credit Roll -> Scrolling on Transparent

    I understand your dilemma, and I’m here to help you create transparent credits for your credit scroll. It seems like you’re using Vegas, and you want the credits’ background to be completely transparent, allowing the video to play normally without any darkening effect. Here’s a step-by-step guide to achieving this:

    1. Create Your Credits:
      • Use your preferred method or plugin to create the credit roll on a separate track in Vegas.
    2. Adjust Transparency:
      • As you mentioned, placing the credits on a track above the video is the right approach.
      • To avoid the black background, click on the credit clip in the timeline.
      • Go to the Video FX tab and look for “Chroma Keyer” or “Color Key” (the exact name may vary based on your version of Vegas).
    3. Apply Chroma Key Effect:
      • Drag the Chroma Keyer or Color Key effect onto your credit clip.
      • In the effect settings, use the eyedropper tool to select the black color as the key color. Adjust the settings until the black background becomes transparent.
    4. Adjusting Transparency Further:
      • If needed, you can fine-tune transparency by adjusting the opacity level of the entire credit clip.
    5. Preview and Adjust:
      • Play back your sequence and make any necessary adjustments to ensure the credits have a transparent background, allowing the video to play normally.
    6. Render and Save:
      • Once satisfied with the result, render your project to save the changes.

    Remember to save your project before making significant changes, and don’t hesitate to experiment with the settings until you achieve the desired transparency. If you encounter any issues or have specific questions about Vegas, feel free to ask for further assistance.

    Best of luck with your credit roll, and I hope this helps!
