- so_129.1
- starts at 129.1 s
- c_fill
- crops to fill the frame exactly
- ar_16:9
- aspect ratio 16 : 9
- w_640
- 640 px wide
- g_auto
- AI picks the focus (the speaker or slide), not a blind centre crop
- f_auto
- best format for each device (e.g. AV1, WebM, MP4, WebP)
- q_auto
- AI-chosen quality: smallest file that still looks right
