Modding the TOTK Trailer Isn't as Hard as You'd Think

I spent about three weeks last year messing with a Zelda Tears Of The Kingdom Gameplay Trailer Modded project. What started as a curiosity turned into a full re-edit where I swapped in custom textures, adjusted the particle shaders, and re-rendered about forty seconds of cutscene footage. It's not complicated, but it does require you to understand a few things that most people overlook. The basic pipeline is straightforward: extract the game's video assets, isolate the sections you want to modify, replace or alter the relevant files, and re-export. For the trailer specifically, you're mostly working with .mp4 source files that are relatively small by modern standards, so you don't need a ridiculous workstation. I was running an RTX 3060 and getting decent frame rates through HandBrake for the final render.

Here's the practical breakdown of how I did it. First, you need to get your hands on the original footage. Most people just rip the official trailer from Nintendo's YouTube channel at the highest available bitrate. Then you strip it down to individual frames if you're planning texture replacements, or you can work with it as a composite video if you're doing shader-level edits. The main file I manipulated was the link model texture set. These are stored in the game's archive files under compressed formats that require specific extraction tools. FF7ResolutionTool was what I used for the model extraction, and Texture Investigator for reading the actual image files. Both are free and have been around since the Switch homebrew scene took off. For the visual changes themselves, I swapped out Link's armor textures for a custom HD version I sourced from a modder's portfolio. The trick is matching the resolution and the UV mapping exactly. If your new texture is even slightly misaligned, you'll get stretching artifacts that are completely unfixable in post. I learned this the hard way after wasting an hour on a render that looked fine until I slowed it down to 0.5x speed.

Audio is where most people drop the ball. The original trailer has its own soundtrack mixed underneath. When you layer custom visual content over it, you need to either keep the audio track as-is or recreate the mix entirely. I kept the original audio and just made sure my renders were synced to the exact frame count. Any drift between video and audio becomes obvious during playback. One edge case that caught me off guard involved the bloom and glow effects in certain Sky Island sequences. The game uses a post-processing pass that adds atmospheric haze to those scenes. When I re-exported my modified video, that bloom effect doubled up and created an overexposed mess. The workaround was straightforward once I figured it out: I had to disable the auto-bloom in my rendering pipeline and manually adjust the exposure values in DaVinci Resolve to match the original look. Rendering time varied significantly depending on the complexity of the changes. Simple texture swaps came out in about twenty minutes on my setup. More involved edits with custom particles and lighting adjustments ran closer to two hours for the same duration of footage. Factor in export compression losses, and you might want to render at a higher bitrate than you think you need, then compress down for the final output.

The biggest mistake beginners make is trying to modify the game files themselves rather than working with the extracted media. These trailers are pre-rendered promotional assets, not live gameplay streams. You're editing video files, not hacking the Switch's memory. Approaching it like a traditional video editing project gets you results much faster than digging into homebrew toolchains. Another issue that comes up repeatedly is format compatibility. The original trailer uses H.264 encoding with a variable bitrate. If you transcode this to something else without preserving the original frame rate and aspect ratio, the timing will drift. I always start by converting to a ProRes intermediate for editing, then export to H.265 for the final deliverable. This avoids generational loss while keeping the file size reasonable. There are some limitations to keep in mind. You're working with whatever resolution and quality Nintendo originally provided. If you upscale a 1080p trailer to 4K, you're interpolating, not discovering new detail. Custom textures can only go so far before the original geometry starts looking obviously wrong. And you cannot add new animated sequences because the source footage is baked. All you're doing is altering what's already there.

If you end up with a modded version you're happy with, the distribution side is simple enough. YouTube accepts direct uploads, and most mod repositories like Nexus or GitHub Pages will host the project files for anyone who wants to see how it was done. I published mine with a full writeup of every tool and setting I used, which ended up being the most useful part of the whole process for people reaching out with follow-up questions. The whole thing usually takes somewhere between six and ten hours total if you're methodical about it. Not bad for a project that looks impressive at first glance but is really just standard video editing with some asset swapping layered on top.
