Every year we try to run a different event that opens Viral Day up to people who've never tried it — and rewards the creators who use the platform every day. In 2025 we ran Creators Weekend, three free days on a weekend. In 2026 we stretched it: welcome to Jupiter-Mars-Week, seven straight days of free video processing on Viral Day, riding the cosmic window where Jupiter and Mars line up in conjunction in the sky.
The idea is the same: you paste the link, the AI watches the video, hands you back clips ready for Reels, Shorts and TikTok — and during this specific week, you pay zero credits for it, within an hourly limit that scales with your plan. This post walks through how the event actually works, what changed since Creators Weekend, and how to squeeze the most out of the window.
When the window is open
The Jupiter-Mars-Week window is fixed and runs on Brasília time:
- Start: Monday, May 25, 2026, at 00:00 BRT
- End: Sunday, May 31, 2026, at 23:59 BRT
Seven straight days. Before midnight on the 25th, everything follows the regular credit flow. After 23:59 on the 31st, same deal — the event simply "closes the portal" and credit billing resumes as usual.
Practical tip: if you want to grab the very first minute, create your account and stay logged in ahead of time. The switch happens at midnight and the counter starts ticking the next second.
How much each plan can process for free per hour
Unlike Creators Weekend (which gave everyone 3 videos per hour regardless of plan), Jupiter-Mars-Week is tiered. The bigger your plan, the bigger the free allowance during the week:
| Your plan | Free videos | Window |
|---|---|---|
| Free trial | 1 video | every 6 hours |
| Lite | 1 video | per hour |
| Creator | 2 videos | per hour |
| Viral | 3 videos | per hour |
One key detail: the window is rolling, not a clock hour. "Last hour" means "now minus 60 minutes," not "from 3pm to 4pm." If you processed a video at 3:37pm, your next free credit (on Lite, for example) unlocks at 4:37pm, not at 4pm.
And regardless of plan, the event keeps one important rule from before: you can only have 1 video processing at a time in the free flow. While your current video is being downloaded, transcribed or clipped, the button to create the next one stays disabled. Same pattern we used in Creators Weekend — it's there so the queue doesn't get clogged for everyone on the GPU side.
Is there a duration cap? Yes — 3 hours per video on fair use
Another change from Creators Weekend: during Jupiter-Mars-Week, each video processed under the free flow can have at most 3 hours of selection. So if you paste a 5-hour podcast and want to clip the segment from hour 5 to hour 10, that's 5 hours of selection — it won't fit in free fair use.
Why? Simple math: processing 5h of video on the cloud costs almost 2x the GPU time of 2h, and we need to keep the infrastructure healthy so everyone can generate clips all week.
The way around it is what we call the opt-out: you toggle "Use my credits" before generating, and the AI processes the full window using credits normally. The flow keeps going, you don't have to wait — you just pay like you would outside the event. That same opt-out also helps when your free hourly counter runs out and you don't want to wait for the next window.
The global 10-hour selection cap per video (which applies year-round, event or not) still holds. Source videos longer than 10 hours are also blocked under any circumstances, except Twitch VODs.
What changed from Creators Weekend
If you joined Creators Weekend in 2025, you'll notice a few important changes:
1. A much longer window. It used to be 3 days (Friday to Sunday). Now it's 7 (Monday to Sunday). More time to test the platform, more time to build a clip backlog you can post all month.
2. Plan-tiered limit. Before, it was 3 videos/hour for everyone. Now each plan has its own ceiling, rewarding existing subscribers.
3. The free tier got a rolling 6h window. During Creators Weekend, free-plan users got 1 video for the whole event. Now you can generate 1 video every 6 hours — meaning you can run up to 28 free videos across 7 days without even paying for a plan.
4. No more banned list. We removed the manual user-blocking system. Unless you were banned for terms abuse, the event applies to you with no exceptions.
5. New 3-hour selection cap. Before, you could clip from any range of any video within your hourly limit. Now each free-processed video maxes out at 3h of selected window — go beyond that and you need to flip "Use my credits."
6. The external API doesn't participate. Free fair use exclusively applies inside the official app. If you use the Viral Day API to integrate with your own systems, you keep paying with credits as always. That prevents third-party automation scripts from burning through the event budget in minutes.
How to get the most out of the week
A few tactics that worked well in previous events:
Prep your backlog the Friday before (May 22). List 10 to 15 long videos you've got sitting around — old livestreams, podcasts, gameplays, talks, horizontal vlogs. Get the public links ready (YouTube, Twitch, Drive or direct upload) before the Monday switch.
Hit the right hour cadence. If you're on Creator (2 videos/hour), processing 2 videos per hour during 12 daily hours across 7 days adds up to 168 processed videos. That's a year's worth of Reels and Shorts.
Set your brand kit on day one. Configuring once (colors, font, logo, watermark) means every clip during the week ships consistently — which boosts retention and brand recognition when you post in sequence.
Don't try to push giant livestreams through fair use. A 6-hour live or a marathon podcast is better split into two or three sessions of up to 3h each, or processed with your own credits (opt-out). You can't stuff 6h into a single fair-use video.
If the limit runs out, toggle "Use my credits." That's the shortcut. You don't get stuck waiting for the next window — you just pay normally. For anyone with spare credits, it's basically a temporary plan upgrade.
What it looks like inside the app
When you open Viral Day during the week, the create-video screen shows:
- A counter indicating how many free videos you have left in the current window (e.g., "2/2 free videos this hour");
- A notice when you hit the limit, with a "Use my credits" button to keep processing;
- An alert if you try to select more than 3h of window, suggesting either trimming the selection or flipping to your own credits;
- The status of your currently processing video — you can't start another until the current one finishes (in the free flow).
In every case, the app explains in plain language what happened and what your next move is. No hidden fine print, no surprise charges.
Wrap-up: touch down while the window is open
Jupiter-Mars-Week is the largest free window we've ever opened on Viral Day — seven straight days, plan-tiered allowances and the option to "unlock" caps at any moment using your own credits. For anyone who's never tested the platform, it's the perfect chance to process a full content backlog at zero cost. For existing subscribers, it's basically a temporary plan upgrade for free.
If you don't have an account yet, create one now — that way you'll already be logged in when the event opens. If you're already a customer, set aside a podcast or live to paste at 12:01am on May 25 and watch the AI churn out the first clips of the cosmic week.
