Why mask not aligning anymore? Help me please.

I'm using Premiere Pro 15.0 on Mac Mini. Sometimes, the mask works perfectly, and sometimes it just doesn't align. Please Help me.

If you are tracking manually do not add or delete nodes.

Make sure footage matches sequence settings.

But how to view the settings of the footage? (Sorry, I'm a beginner at Premiere Pro)

Start at the beginning:

Will it happen when the FPS is different but everything else is the same?

Hi Jerry,

Sorry. Are you saying the source footage is at a different frame rate than the sequence? That should not matter. I tried it myself and had no trouble. That said, it is always a good idea if your source footage matches your sequence settings if at all possible. Handling files in any way, like rendering and playback, works better with matching settings.

Back to masking, controls are found in the Effect Controls panel. You might try experimenting with simpler masks to get the hang of the workflow. Creating a single complicated mask is not a beginner-friendly technique to start with, unfortunately. 

Are you masking a human figure? It looks like you are. That may take multiple masks to control appropriately. While possible in Premiere Pro, multiple mask handling and masking (rotoscoping) human beings are more in motion design, and After Effects would be the better tool for that.

I hope we can help you achieve what you want, though.

Thanks,
Kevin

Thank you so much for answering me, what you're talking about is exactly what I'm doing, I'll try to use After Effects to solve the problem, Will it be convenient for you if I ask you questions again in the future?

[Kevin-Monahan]

Sure, Jerry. Let me know any difficulties you are facing. Look up the topic of After Effects rotoscoping online for additional training. You can also use roto brush for such effects instead of traditional masks. Rotoscoping is very satisfying work; however, it is tedious.
