Premiere ‘s super convenient function.
I will introduce the function to synchronize two or more videos based on the recorded audio as a reference.

There are two methods.

Please select by personal preference.

Read the image → Select all the images you want to synchronize → Right click → Create multi-camera sequence → Select synchronization point as “audio”

* By the way, the audio of the video file you selected earlier will be used (so it is better for you to select the one that has clean sound)

Success (sometimes failing · · · material is bad (sound is small etc.)) Once done, it is completed in the project window.
Double-click it, it will be displayed in the source window so play it and check it.
By the way, the folder that you made arbitrarily stores the material of the synchronized video.

Another way.

Read the video → drag and drop the video you want to synchronize to the right timeline window → select all on the timeline window → select synchronization from the menu clip → select the audio point to be synchronized and click OK

Status not yet synchronized

If the synchronization is successful, you can see that the audio waveforms are consistent.

Images synchronized with the program window are displayed.

Images are overlapped when you are done
By changing the size of each screen from the effect window you can display all the images.

I will introduce the operation of the effect window on another occasion.
