How to use auto reframe to follow object when zoomed in but keeping the same aspect ratio

[stevenhulme]

• I would like to shoot a 4k video, zoom in to make it full HD but then use auto reframe (or other means) on premier pro to follow the object. Auto reframe appears to work well when going from 16:9 to other aspect ratios but not when keeping the same ratio and zooming in. 
  
  
• Is this even possible?

Hey stevenhulme,

Welcome to the community. Auto Reframe requires the sequence aspect ratio to be different than the source file aspect ratio. You can try motion-tracking the object in After Effects or manually placing position keyframes in Premiere Pro.

Thanks,

Ishan

I have the same question. I have a 4K video of a stage where a standup comedian does his thing. I zoomed in to get a medium shot, but he moves around and out of frame.

Instead of painstakingly putting manual keyframes everywhere on the 1h30m timeline, I would love the same automatic workflow as the Auto Reframe WITHOUT changing the aspect ratio.

Thank you Ishan Y for your workaround. Unfortunately motion-tracking will add a very unnatural robotic camera movement to the video while following the subject. The Adobe Sensei in Auto reframe does a more natural job, but doesn't work when keeping aspect ratios...

Auto reframe is only for say taking a 1920x1080 sequence and reformatting it as best "guessed" for say 1080x1080 to use on a social platform.

In other words, it is for moving set things such as graphics to a 'usable' location, when changing frame sizes ... especially when the aspect ratio changes.

It does not have any tracking capabilities, nor is meant for such work.

You need to use masks and tracking processes for what you are trying to do.

Can somebody code a plugin please? I have a feeling this feature will be greatly appreciated by a lot of people 🙂

I tried to cheat the system by making a duplicate sequence of my strung-out camera shot, changing the sequence size from 3840 x 2160 (16:9) to 2880 x 1620 (16:9), then changing 1620 to 1621, thinking this would qualify as a "different sized sequence" but got no result. Thought I was smarter than Sensei, but it seems as if I'm still a young grasshopper. lol
