Instant uses the middle of each clip and joins them with hard cuts in a few seconds. Accurate also checks every clip for the steadiest part, slower. Only clips shorter than 1.5 s are left out. Tap the star on a clip in Media to always include it. After the edit you can add or remove any clip from the list.
Rendered parts play smoothly (white line on the timeline). The export always renders at full quality.
