Hello i'm sorry I don't know how to post my own post... I want to ask how to continue recording on dji go 4 app?? it only records 5 min then starts a new 5 min video. Can someone help me? I have the P4P.

There is a 4Gb limit on video file size on the micro sd cards. If the video file exceeds that size, a new video file is started.  Have a look at the video file size on your micro sd card as I would have thought you might get more than 5 minutes but it also depends on the format and quality you are shooting in.

If you want to get longer videos then you would need to reduce quality down.
If you want to record at 4k then you will need to stitch your videos together post flight

2#'s reply is spot on. Post-production is required if you need high quality video.
