I cut out an object from a jpg image and made a new jpg image with transparent background. Tested it on image editing program - the background is indeed transparent.
However, when i try to superimpose the image with transparent background on a video in PrE, the image is shown with a white background.
How do i remove that unwanted white background?
JPEG cannot contain Transparency. In your Image editing program, I would choose PNG. If your Image editor is Photoshop (either regular, or Elements), you can also Save_As PSD, which will work fine in Premiere.
When one creates Transparency, but then chooses a Save_As, such as JPEG, the Image is flattened onto a white background.
Thank you Bill.
While waiting for the answer I managed to remove white background with Chroma Key effect, but as a side effect the object (an airplane in this case) picked up some of the colors from the video it was superimposed on. So I thought some further tinkering is needed to complete the job but your answer saved me from this
Simply saved my image as PNG and I have no problems anymore
In many Image editors, Transparency is not clearly deliniated, and it just looks white. With display settings in Photoshop, Transparency will be shown as a checkerboard pattern, but when one does a Save_As to JPEG, that clearly goes white, alerting the user to the lack of Transparency in the JPEG.
Good luck, and happy editing.
PS - When you get your plane crashing into the tree, please post a link to YouTube, Vimeo, etc., so that we can see it.
How are you Bill?
Still interested in my little silly project?
