VLC "Lost " video frames is not necessarily an indication of an export problem. That statistic tells you how many frames VLC failed to display in order to maintain realtime playback. If it feels like it is falling behind then it will skip displaying a frame to avoid video falling behind audio. Shotcut does something similar when Settings > Realtime (frame dropping) is on. Small differences in this statistic does not indicate an export issue. Also, your screenshot for “OBS Raw Recording Footage” shows 0 frames displayed.
