I saw your other thread about this... yes, PP can do this.
The short version:
1. Place all clips on separate tracks, on top of each other. If you have a separate audio file that you're using to replace the camera audios, then put that in an audio track below the videos.
2. Select all, right click, and choose "Synchronize". In the dialog, choose the Audio option and then OK.
2a. Of course, this only works if the shots were actually shot at the same time, of the same event.
2b. If you get a dialog that says "a match could not be found"... then go up to the Sequence menu and choose Render Audio. Then you have to try step 2 again.
2c. If you are working with shots that weren't actually shot at the same time/place, then Step 2 is out of the question. If you try it, you'll still get "a match could not be found", and Rendering Audio is not the solution. In that case, a match could not be found because... there is no match. The audio isn't the same. In that case you have to manually synchronize all the video and audio clips on the timeline.
3. You should see after a moment that all the clips have been shifted to line up with audio matching (assuming that the Synchronize command did the job for you... whether you used the Synchronize command, or manually synced, next is:)
4. Mute the audio tracks you don't want to hear, so only one audio track is playing.
5: Then you'll have to use the Crop effect, or Motion effects (scale, position, etc) to resize/replace each video where you want it on the screen. This part is subjective... do it however you like.
Hope that helps.
BTW... for future reference, the way you used the word "frame" is a tad confusing... that's why the person who first answered your other post didn't know what you meant. A "frame" is one still image from the video... one instant in time. Many frames strung together create a video (24 frames per second, or 30 FPS, 60 FPS, etc). It will be easier to understand if you use the term "camera" (as in multicamera) or shot or clip. I think folks would have known sooner what you were after. 🙂
