Scale to Frame Size vs Fit to Frame Size in Premiere Pro

The Scale to Frame Size and the Fit to Frame Size features in Premiere Pro sound like they do the same thing, but they don’t. Plus, their names are not all that logical, so people tend to misinterpret what they do. I wrote an article for the Film Editing Pro blog named “The Editor’s Guide To Working With Still Images In Premiere Pro” where this was just one of many topics. You can read the whole article on their web pages. Here’s an excerpt from the article, about Sale/Set to Frame Size.

Scale to Frame Size vs Fit to Frame Size in Premiere Pro

If you want images and video to always scale to fit inside the size of the sequence, you can use one of two methods: Scale to Frame Size or Fit to Frame Size. They can both be found in the right-click menu for clips in the timeline, and in the Clip menu, under Video Options.

So, what’s the difference?

Scale to Frame Size

The Scale to Frame Size option will resample your image at the size of the sequence. So, if you use this on an image that’s double the width of the sequence, you end up with an image that’s ¼ of the original pixel size, while the Scale will be set to 100%. This is a great way to reduce the strain on the system, but it will degrade the image if you scale it further.

Set to Frame Size

The Set to Frame Size option, on the other hand, will not resample the image, but instead set Scale in the Effect Controls panel to whatever it needs to be to fit the image inside the frame. In my case, since the image is 3840 px wide, that’s 50% for a 16/9 image. All the pixels are still intact, which is great when you want to scale the image further in the Effect Controls panel, but you’ll need more computer power.

How to use them

Scale to Frame Size is also available in the bin. Select the clips you want to automatically scale to frame size, and click Clip > Video Options > Scale to Frame Size. When you put the clips on the timeline, they will auto-scale.

If you use this feature all the time, you should set this in your preferences. Click Preferences > Media > Default Media Scaling, and set it to Set to Frame Size. Or use Scale to Frame Size to reduce the strain on the computer, and remember to change it to Set to Frame Size for the clips you want to scale further, before you start scaling them.

Default Scale or Fit to Frame Size

In reality, the Scale/Set to Frame Size options are not as useful as you’d think. Most images from a DSLR will not be 16/9 aspect ratio, so the scaling will result in letterbox or pillar box looks with black bars.

A much better approach is to create a Motion preset that scales the images to the desired size, so you don’t get any black bars.

Make Scaling Presets

To make a preset like this, set scale to whatever it needs to be to fill the whole frame. In my case, it was 50%. Then right-click on the word Motion in the Effect Controls panel and choose Save Preset. Name it 50% Scale or something similar. Next time you need to scale 70 images, just select them all in the timeline, and throw this preset on one of them. Perfect scaling in less than a second!

    “Default Set-to-framesize” has an annoying bug, where if it is turned on you can’t use cut-paste to move things around the timeline, because it will strip out any motion that was previously applied. In my view, the default should only apply to when you add new stills to the timeline.

  3. I want to learn from the basic. I shoot videos but I don’t edit I always pay for editing. Please could you teach me from the start up to advanced level.

    • On every page of PremierePro.net you will find a sidebar with links to “Premiere Pro Classroom in a Book”, which is a beginners book, and to “The Cool Stuff in Premiere Pro” which is an advanced book. After reading both of these, you will have mastered the art of editing in Premiere Pro.

  4. Thank you very much for sharing your information.

    If I scale/Set to frame size on a 4k or 2k clip to a1080p sequence, will it affect/reduce the quality of the clip? I want to know if the quality will remain when exported as 1080p?

    • Will it reduce the quality? Yes, of course—you’re throwing away 3/4 of the pixels of the 4k image when you scale it down to 1920 x 1080. If you’re asking of the 4k image will have the same quality as 1920 x 1080 material when you scale it down, the answer is yes. If you just scale it down to fit the frame, there’s no difference between Scale to Frame Size and Set to Frame Size. But if you scale it again, after scaling it to fit the new frame size, there is a difference. If you use Scale to Frame Size and scale it up again a bit to zoom into the image, you’re losing resolution. If you use Set to Frame Size and scale it up again, you’re NOT losing resolution (until you go past 100% scale).

    How about Fit-to-screen? I mean that if I use your method, the images are still lost some parts. I just want to stretch the images to whole screen, the objects maybe look “fat” but it’s ok if the ratio close to the default (16:9 …)
