I can then provide specific code examples, such as the exact FFmpeg command or HTML/CSS setup.

Logic: Map inputs 0-62 to positions 0-62 using the xstack or overlay filters in a configuration [1, 2]. 3x21 mp4

Based on standard video production terminology, here is the development plan to create this feature: 1. Feature Definition I can then provide specific code examples, such

Highly dependent on individual panel aspect ratios; likely to result in a very tall vertical video. Implementation Steps (Technical)

"3x21 mp4" describes an MP4 container housing a video grid, most likely 3 columns by 21 rows , resulting in 63 individual video feeds or image panels playing simultaneously in a single file [1, 2].
