Best way to delete recordings from iPhone?

What is the best way to delete videos recorded by Folocam on the iPhone?

When the camera preview is showing in FoloCam, swipe left to see the list of videos. Tap the delete icon on a video’s row to delete it along with its accompanying .srt and .log files, which aren’t shown in the list.

Thanks!

So far, this is an excellent app. The camera tracks the ball very well. I’m using an iPhone 14 Pro, Soccer Pro setting at 2x, and recording and streaming to TeamSnap One.

If I used a new iPhone, would the ball be tracked even faster? Or, if I just streamed and did not record, would that increase performance?
