Activity Forums Adobe Premiere Pro Zoom into image while keeping the same pillarbox ratio

  • Zoom into image while keeping the same pillarbox ratio

    Posted by Jamie Carsten on August 27, 2018 at 5:22 am

    Hi there,

    I’m new to Premiere Pro and I’m having a little difficulty with my first edit, which was supposed to be a simple slideshow!

    Firstly, my photos are different aspect ratios (mostly a mix between iPhone portrait, square and landscape). I selected Scale to Frame Size, which has given me varying degrees of pillarboxing, which I’m comfortable with.

    The problem is when I try to key frame zoom ins and outs, which I do using the Scale animation in Effect Controls. See middle clip in video here. https://youtu.be/p-WRdOkDXEI

    What I’d expect is the pillarboxing to stay the same. I.e. when I zoom in on the image. I don’t want the image to gradually eat into the pillarboxes. Wouldn’t standard behavior be if you zoom into or out of an image the aspect ratio and position of the image relative to the overall screen stays the same, i.e. the pillarboxing doesn’t get any more or less? Otherwise I’m going to have a video with black bars constantly increasing and decreasing.

    Does anyone know how to overcome this?

    Thanks a lot ☺
    Jamie

    Generate some black video, crop it/mask it from the middle and add it on the topmost track.

    So there’s no simple way to do this? ☹ I wanted to do a blurry background behind each image individually rather than the black. Would this be the same process? I’m not sure how to do any of what you’ve said. Would there be any tutorials that could help me?

    This would surely be a common problem for people needing to zoom into photos/videos where there is letterboxing or pillarboxing? I hoped there might be a zoom effect rather than a scale effect that would allow me to zoom into the image without causing the image to grow or shrink on the screen, however I can’t see anything. 🙁

    Try this… put a Basic 3D effect onto your picture, then use the Distance to Image to move in. I think it should do what you want, but yes, typically you would create a matte to cut out where you want your background to show outside of your image.

    Thanks Todd. I tried that but unfortunately it also causes the image to increase/decrease in size, rather than zoom into the image without the image position changing. See here: https://youtu.be/aOSXl_lVSeQ

    Is there a simple step-by-step to follow to perform the traditional mask approach referred to? I’m a total newbie to Premiere Pro so any simple instructions are massively appreciated! ☺ What I’m guessing is I create a new video track above the image track. Then say for each image I make a copy of the image and place it into the track above, and add a gaussian blur. From there I’m then lost as to how I crop and mask!

    Thanks Dave.

    Happy to spend the time masking each image as it’s a special video for me. I’ve done this copying the track below, scaling to full size and adding guassian blur. I assume what I need to do is add this to the top track then add a mask somehow. Would anyone know how to do this? Thanks so much!

    Duplicate your footage above your footage. Let’s say that is track 2. Then generate a solid or black video and put it on track 3. Use a mask in the opacity tools to make an aspect ratio you want. Add a track matte key to the footage in track 2 and choose the matte as track 3. Now you can scale and blur and do whatever the second track and the footage on the first track will show trough in the shape of the mask you made.

    Ha! Worked on a dslr pict I had. Scaled to desired size and used the 3d to zoom in.
    Anyhow, using a matte will give you consistent results and be the best way to accomplish this. It’s really quite simple. Check out some Track Matte tutorials online. There are a bazillion of them, but you’ll probably just need one or two.

    Wow so I need 3 tracks just to be able to do this? I’m also not following the instructions because I’m a beginner. All the track matte tutorials are things like this (https://www.google.ca/search?q=track+matte+premiere+pro&oq=track+m&aqs=chrome.0.69i59l2j69i60l2j69i57j69i60.1427j0j7&sourceid=chrome&ie=UTF-80) which I don’t see how it applies to me.

    Tero is there any chance of a quick video tutorial of that? I can’t figure that out based on reading that.

    Even 1 minute on 1 clip would be good showing the process. Am I adding the mask to the black video in track 3? I’m not sure how to set it exactly to the size of my image. For example my original image position (and what I want to keep my image to when zooming in and out) is 960 x 540, thus I assume my mask on track 3 needs to be this exactly as well? When doing the mask I can see the ellipse mask, polygon mask and pen mask. Not sure if any of these tools give me the ability to set an exact pixel mask? Thanks

    Doesn’t the blurry, full screen background have to be the first track? I.e. behind the image I want to zoom into and out of?
