Как заменять фон на видео длинной в час? (полный гайд)

Neural networks are great at replacing backgrounds in videos while preserving a person's face, but the generation process only lasts 10-15 seconds. In this episode, I show how to overcome this limitation and replace the background on a long video—a podcast, a talking head, or even an hour-long clip. 🎬 Try background replacement yourself → https://syntx.ai/?utm_source=youtube&... 📚 Prompts from the episode → https://bit.ly/fonsyntx I'm testing these methods on real-life shoots: Omni Flash (and why it doesn't work), Seedance 2.0, and Switch X. I prepare backgrounds in Seedream 5 Pro, assemble everything in DaVinci, shoot in the studio and on a regular phone without lighting, and finally, I calculate how much an hour of such generation would cost and whether it's worth it. 🔥 Promo code "FON15" — 15% discount for new users! 🔗 Useful links: 🌐 Website → https://syntx.ai/?utm_source=&utm_med... 🤖 Telegram Bot → https://telegram.me/syntxaibot?start=... 🏫 School → https://school.syntx.ai/ 📚 Academy (free) → https://academy.syntx.ai/ 👥 SYNTX FAMILY (320,000+ members) → https://bit.ly/SyntxFamily — the largest AI community on Telegram.
