The title of today's article is not a mistake - that's a typical filename for an EXOR Studios trailer in the final stages of its production. Looking at our gameplay trailers, you'd never expect that their production takes a long time - it's just a couple of gameplay clips stitched together, after all. However, the opposite is true. Our trailers are a result of a long process that is a bit messy at times, but always very fun and definitely more interesting than the file name suggests. It's also a process that makes the game itself better in some unexpected ways. This article will talk about gameplay trailers only. We have a couple of CG trailers out there, but the workflow is completely different in their case.
Our very first gameplay trailer for The Riftbreaker. What you can see in the video is pretty much EVERYTHING we had in the game at that point. If you pay attention to details, you will quickly notice that there are only three enemies shown for the entire duration of the trailer. That's because these are the only ones we had. There is also one voiceline that is spoken by yours truly. Can you tell which one? Paweł spent an entire week setting up the map for the last scene with the horde and nukes!
Every gameplay trailer we put out is either made fully in-house or in collaboration with an outside editing company. Before a single frame gets recorded, we write a paper draft of the trailer, fully scripting each second of screen time. What do we want to show? What does the mech look like? What kind of weapons are in use? Which setting are we in? We try to make each scene robust enough to convey its own story, but we also pay close attention to continuity between shots. We don't want to create a blur of cool-looking clips stitched together for no reason. That's a music video, not a game trailer. If a scene cannot justify its own existence in the context of the whole trailer, it doesn't make the cut, no matter how good it is.
All the placeholders and missing features can be spotted easily in this commentary trailer. Making a trailer way before launch is basically the art of hiding what's unfinished. You can also see how badly we used to play this game!
The Launch trailer is basically a remake of the video above, but now with production-quality assets and very few placeholders.
The next step is, quite surprisingly, choosing the right music. We pick the track before we start recording a single scene, because the whole trailer gets cut to the beat of music. Sometimes we license something from various stock asset marketplaces. Other times, when we want a more custom treatment, we go straight to our music composer, Marcin Pukaluk. We give him the trailer script and describe what emotions we want to convey and what style we want to hear. After some time, Marcin comes back with a couple of prototypes, one of which gets developed into the real soundtrack of the trailer. After that, we are finally ready to start shooting the actual scenes.
We decided to do a couple of separate trailers focused on the core pillars of Riftbreaker gameplay - one for building and one for fighting. Our inspiration for the building trailer was the Satisfactory reveal trailer. Groovy music with a driving bassline and relaxed gameplay showing that you can totally get 'in the zone' and build for hours.
Regardless of whether we decide to edit the trailer in-house or outsource the editing, we have to record all the footage ourselves. If you see something on the screen in one of our trailers, someone on our team had to actually play it. Trailers usually accompany our World Expansions, which add a ton of new content we want to show off. There is a small caveat, though. Trailers have to be ready before the release date, which means that we have to record good footage while actively avoiding showing unfinished elements of those updates. The first takes are usually shot on a buggy developer build, full of placeholder assets and performance problems that would make anyone flinch. We have made peace with the fact that all of these recordings are headed straight to the trash. However, they are instrumental in creating the first draft of the trailer - a proof of concept that shows whether our paper plans make sense in reality, before we commit them full speed.
The second gameplay pillar - weapons and combat. A big portion of this trailer was recorded on a custom, pre-made map. We built the entire base in the editor, set up custom spawn points, and scripted camera movement a couple of times. The scene with the horde heading towards the base was recorded at half speed and then sped up, because that version of the game couldn't handle that many units and maintain stable 60 FPS. This is also the reason why we recorded all the base defense scenes separately for north, south, east, and west.
That first draft is also the point where the trailer quietly turns into a development tool. We sit down and watch it with two very different questions in mind. The first one is about coverage - what did we plan to show, and what do we simply not have yet? The second one is a lot harsher. What looks bad? What is obviously unfinished? What needs another round of work before we'd be comfortable putting it in front of you? A trailer is merciless in this respect. Seeing your own game in short, isolated clips that you replay over and over exposes every rough edge you had stopped noticing during day-to-day development.
This is our pride and joy. We put in a lot of effort into this trailer, even though we outsourced the editing to Radikal Studio - our go-to partners for this kind of work. It was also fun speaking to Jon Bailey aka Epic Voice Guy and hearing his regular voice.
After that step, we enter the stage of recording scenes with the intention of actually using them in the release version of the trailer. We do this in stages - as the features and assets our scenes depend on mature, we record them and replace the placeholder footage in the trailer draft. By preparing the proof-of-concept trailer version beforehand, we can simply drop the replacement footage into the project timeline rather than starting from scratch. Recording the 'final' scenes is difficult in ways that have nothing to do with creativity or execution. There are dozens of small errors that can ruin a perfect scene. Frame drops, random notifications, system sounds, our own music we forgot to mute, or random rendering glitches. These are the kinds of errors you usually notice only when reviewing the footage and usually mean a retake is required.
For the second expansion, we went full indie and did everything ourselves. This is the first showable draft, complete with a timer, scene notes, and LOTS of placeholders. We even forgot that we used the Zombie Driver boss as a placeholder!
After 37423921 iterations, this is what we ended up with. It's the same, but different!
Retakes are the most demanding part of our trailer projects. Our games have no 'demo' mode. We can't pre-program the mech movement, enemy behavior, building up the base, or any other in-game actions. Nothing fakes the footage for us. (The only thing we can control to some degree is the camera movement.) Every single action in every single shot has to be played live, exactly as a real player would. This usually means dozens of attempts to shoot a scene that we pictured on paper. In the most hardcore cases, we spent eight hours just to get eight seconds of footage right. The amount of effort necessary compounds when we record multiplayer scenes - double the players, double the points of failure. Nowadays, with thousands of gameplay hours under our belts, spending eight hours on one scene is unlikely. However, back in the early days it was a real possibility.
The third expansion was an opportunity to show the graphics upgrade the game has received. Better liquid rendering, volumetrics, new shading method. This was a fun one!
This is exactly why trailer production ends up improving the game, and honestly, it might be the most valuable side effect of the whole thing. Since nothing on screen is faked, the only way to make a shot look better is to actually make the game better - so that's exactly what we do. We fix animation errors, level propping, and visual effects that are too subdued or too pronounced. On top of that, replaying the same encounter dozens of times in a row is a brutally effective way to find bugs, and we fix a mass of them in the process. For the length of a trailer project, a large part of the studio is focused on nothing but making the game look and feel as good as it possibly can. All of that work goes straight into the update you download. Improved visuals, better-feeling weapons, smoother animations, and the squashed bugs aren't trailer magic that evaporates once the video ends - they're in the build, because they had to be in the build for us to record the trailer in the first place. You'll never see the footage we threw in the trash, but you do get to play the game that came out of making it.
These longer 'developer overview' trailers are our favorite. They allow us to talk about everything we want and show off what we have been working on in greater detail. They are easier to make as well, since the editing doesn't have to be so tight. However, this trailer required us to learn a new skill - recording co-op scenes.
Once we have all the scenes we actually want, we get rid of the placeholder footage and do a final editing pass, choosing the right spots for transitions and cuts. After that, we move on to editing audio, where things get surprisingly technical. We pull stem tracks from our trailer video project, with sound effects, voiceovers, and music all separated into their own WAV files, and put them in REAPER, a digital audio workstation. Since SFX, VO, and music were not explicitly designed to work together, they often fight for the same frequency space. The result is a muddy mess that is very unpleasant to listen to. Getting all sounds to coexist peacefully requires a lot of sidechain compression, careful EQing, and volume automation. After mixing, the trailer is almost ready for release.
This is a preview of the co-op gameplay trailer before we sent it to Radikal Studio for editing. This one was cut to "How Much Is The Fish?" by Scooter. It was never a candidate for the real thing, obviously, but it had the exact BPM and the build we needed to test whether the co-op beats landed. Every explosion in here is sitting on a Scooter drop.

We publish our trailers on various platforms - social media, video hosting sites, digital storefronts, and many others. Many of them have different technical requirements for a video. Bitrate, file size, file format, codec used, title cards, mnemonics, closed captions, thumbnails - all of them can make or break your upload. We create a list of the required trailer versions and render separate versions for each hosting service. The number of versions we have to produce can easily go into double digits. However, at this point we usually see the light at the end of the tunnel (the headlight of an incoming deadline), making the end of the trailer project, so time flies when you're doing it.
The latest trailer we made - a descriptive summary of the World Expansion 4 update. The production went very smoothly on this one, as we had a lot of experience with recording both solo and co-op scenes. Fun fact: all the panoramic scenery shots are made with our in-game camera by hiding the mech and removing all walking effects.
Adding it all up, from the first paper draft to the final platform-specific export, a trailer usually goes through more than thirty iterations before we consider it done - for something that runs a minute and a half… Is it worth it? ABSOLUTELY. A trailer is the single most important asset we have for getting a game discovered in the first place, and it doubles as one of the most intense polish passes our games ever get. That is worth every retake, rerender, and every cup of coffee.
