Hometown – rainy season | PixVerse V4.5

This article reveals the planning and strategy behind one of HavefunwithAIch's YouTube releases—from thumbnails to audience targeting.

🌧️ Hometown: Embracing the Rainy Season in Japan

Welcome to our Hometown series, where we explore the beauty of Japan's seasonal transitions.
This time, we're stepping slightly outside the typical four-season framework to introduce a uniquely Japanese phenomenon—the rainy season, or "tsuyu", which lasts only about a month yet leaves a lasting impression.

🎥 About the Video: A PixVerse V4.5 Collaboration

This episode is part of a PixVerse V4.5 KOL collaboration, though as always, the promotional elements are kept minimal (while the YouTube description remains purely promotional).

Let us say this upfront:
V4.5 might feel "incomplete" at first glance.
But in truth, it’s anything but. This version is clearly designed with Luma, Ray2, and Vidu in mind—pushing the platform closer to their territory.

🖼️ The Technical Leap: True 4K Support

A major highlight is its ability to natively upscale to 4K.
While PixVerse has long supported 4K upscalers, V4.5 now integrates 4K rendering directly—possibly in response to Ray2’s growing popularity.

This means creators no longer have to worry whether their editing software can handle upscaling:
4K is now available to everyone using PixVerse.
(Note: Among mainstream editors, only Adobe Premiere Pro and DaVinci Resolve currently support 4K upscaling natively.)

⏱️ Extended Video Length & Character Retention

Another critical feature: video extension.
Unlike Vidu, PixVerse V4.5 now allows users to extend clips without having to insert images—just like Ray2. This is incredibly important for us at HavefunwithAIch, as it preserves character consistency and continuity at a high precision.

🔊 Sound Design: Layered, Intelligent, and Prompt-Responsive

The audio engine now supports layered sound structures that are generated in sync with the video itself.
Better yet, it remains responsive to natural language prompts—as before—but now allows easier regeneration when the sound doesn't feel right.

🚗 Comparing AI Tools (With a Car Analogy)

To put it simply:

• Ray2 is like a theme park go-kart — you can’t really control it.
• Vidu is a manual transmission car (MT) — full control, but complex.
• PixVerse is automatic (AT) — smooth, predictable, and practical.

📍 Highlights from the Film: Nature, Rain, and Memory

The short film is a collection of mini-scenes, but don’t miss:

• The waterfalls and marsh of Oirase Gorge
• The seasonal flowers of Nikko
• The thunderstorm in Tokyo

These visuals are based on real locations. If you ever visit Japan during the rainy season, chances are you’ll witness very similar sights.

The marsh in particular is possibly the upper limit of what AI can currently render in clean 4K.
Dynamic camera motion in such a setting? Still beyond what any AI has achieved.

As for the waterfall... it might be the most visually impressive cut in the channel’s history:
the momentum of water crashing into the basin, the misty spray, the smooth flow into the river—absolutely stunning detail.

🐦 Realism in the Details

The birdsong in Nikko was recreated with specific species in mind, matching what you’d likely hear in real life during this season.
These aren't just "AI sounds"—they're intentionally curated audio details.

⚡ A Memory from Tokyo

Yes, Tokyo really does get storms like the one depicted.
The risk of flash flooding still exists in many urban areas across Japan.

In fact, the scene shown in this video is based on a personal memory—from when I was half the height I am today.
Surprisingly, such intense storms are more common near urban centers than you'd expect.
Please stay safe if you visit during rainy season.

Not just a YouTube channel — a channel where tools are tested and compared with extensive knowledge and practice, pushing the limits of AI.
