Q.Does Instagram Reels support WebM uploads?

Yes! Instagram, TikTok, YouTube Shorts, and LinkedIn all natively accept modern WebM video containers and re-encode them with maximum visual clarity.

Q.Why does MP4 export tear on canvas video editors?

Client-side MP4 transcoders often drop keyframes (I-frames) when encoding at 60FPS, causing severe pixel tearing during fast motion or forward seeking.
