How do you edit Minecraft 100 days videos for YouTube?

The steps:

1. Pick the shape: one 100-day video, an episodic hardcore series, or a 1,000-day full movie.
2. Log the recording by in-game day.
3. Build the arc from the goal set on day one.
4. Compress the grind with a day counter on screen.
5. Write and record the voiceover to the cut.
6. Slow down for hardcore close calls.
7. Give every big build a reveal.
8. Finish with chapters, the hook and the thumbnail.

Step 1: Pick the shape before you open the recording

“100 days” covers three different edits, and the cut changes with each one:

• One 100-day video. A complete story in a single upload. On October 18, 2026, Mozi’s last 12 uploads, all of them 100-day videos, ran 1:13:48 to 1:33:52, with a median of 1:26:12. The 100-day videos on Cryptozoology (58:46 to 1:21:00) and utters (1:03:32 to 1:26:55) sit in the same range.
• An episodic hardcore series. One world, many episodes. Rubik’s Dedsafio 4 episodes #2 to #8 ran 30:26 to 37:18 each. Every episode needs its own goal and its own ending.
• A 1,000-day full movie. In the first 15 results of a “minecraft hardcore series” search the same day, ten were 1,000-day (or longer) full movies, running 2:14:14 to 11:51:49. These are edited like a film with acts and chapters.

Decide which one you are making first. A 100-day recording edited as an episode feels unfinished, and a series episode edited like a full 100 days feels rushed.

Read from YouTube on October 18, 2026. On Cryptozoology and utters, the 100-day videos are the longest uploads on the list; their shorter videos are single builds or projects.

Step 2: Log the recording by in-game day

A 100 days recording can be ten or twenty hours of raw footage. Scrubbing it from the start is hopeless. Log it by day instead: a simple sheet with the day range, what happened, and a timestamp in the raw file. Day 1 to 3: shelter and first tools. Day 14: found a village. Day 31: nearly died to a creeper. Day 60 to 75: built the farm.

If you record yourself, make the log easy: say the day out loud when it changes, drop a marker for anything that felt big, and note close calls the moment they happen. How to record gameplay for your editor covers what else to capture. The log is what makes the rest of the edit possible.

Step 3: Build the arc from the goal set on day one

A 100 days video works when it makes a promise early and keeps it. Look at the titles: “Building The ULTIMATE FARM”, “ON A MOUNTAIN”, “a Cozy Castle”. The goal is in the title, and the video is the story of reaching it.

From the log, mark four kinds of moments:

• The goal. Said clearly in the first minutes, ideally with a list of what has to happen by day 100.
• Milestones. Each item on that list getting done. These are the chapter points.
• Setbacks. A lost base, a raid, a near death. A 100 days video with no setback has no tension.
• The finish. The final build, a tour, and an honest look back at the list.

Everything else is a candidate for a montage or the floor. Assemble the timeline in that order before you trim anything.

Step 4: Compress the grind with a day counter on screen

Mining, farming, gathering and travelling take most of the in-game time and should take very little of the runtime. Turn each stretch of grind into a short montage: a few quick shots, a speed ramp or a timelapse, and music that carries it. Then get back to a moment that matters.

Keep a day counter on screen for the whole video, in the same place and style every time. When the video jumps several days, let the counter tick forward fast or use a short title card. The viewer should never wonder what day it is or how much time just passed.

Montages are also where a 100 days video goes slow if you aren’t careful. If a montage runs longer than the beat it leads to, it is too long.

Step 5: Write and record the voiceover to the cut

Most 100 days videos are narrated. The narration tells the story the footage can’t: why this build, what went wrong, what the player was thinking. Write it after the picture is assembled, when you know the ending and can set up what matters early.

Practical order: lock a rough cut, write the narration over it, record it, then trim the picture to fit. Keep live commentary for the moments where the reaction itself is the content, like a close call, and drop it everywhere else so it doesn’t fight the narration. Keep the voice on top of the game audio and music, and check the final level with the YouTube loudness checker.

Step 6: Slow down for hardcore close calls

In hardcore, one death ends the world, so every close call is the most important moment in its section. Give it room. Show what led to it, let it play at real speed, zoom in on the health bar when the hearts drop, and hold a beat afterwards for the reaction.

Don’t cut a close call down to a few seconds to save time. It is the payoff of all the grind you compressed. And don’t fake one: if the hearts never dropped, a dramatic sound effect over a safe moment reads as a lie.

In a hardcore series, start each episode with a quick reminder of what is at stake and what was lost before. A new viewer needs to know that dying here means the series ends.

Step 7: Give every big build a reveal

The build is often what the title promises, so it deserves its own moment. Show the empty spot first, compress the building into a timelapse, then reveal the finished build with a slow camera move and a music change. A before and after side by side is clear and cheap.

If the recording has cinematic camera shots of the finished world, save them for the big reveals and the final tour. Used everywhere, they stop meaning anything.

Step 8: Finish with chapters, the hook and the thumbnail

Add chapters by day range (Day 1 to 10: Shelter. Day 11 to 30: The village). In a video over an hour, viewers use them to come back, and they show the structure at a glance.

Write the first 30 seconds last. Open with the goal and a flash of the hardest moment or the final build, then start day one. The thumbnail should show the same promise: the final build or the danger, readable on a phone. Check it with the thumbnail preview tool.

Common mistakes in 100 days edits

• Cutting in recording order. Build the arc from the log first.
• No goal in the first minutes. Without it, the video is a list of days.
• Montages longer than the beats. The grind should be quick.
• Close calls cut too short. They are the payoff, not filler.
• A day counter that moves around or disappears. Keep it fixed.
• Narration recorded before the cut. It can’t set up an ending it doesn’t know.

What I have actually edited

I haven’t edited a 100 days series for a client, so the steps above are how I would run one, built from the closest work I do. I edit Minecraft survival and horror videos for Puff, including Surviving The Obsessed In Hardcore Minecraft and Surviving 99 Nights in Minecraft's Evil Forest. For Swaylemc I edit Minecraft horror full movies of about 105 minutes, such as It Heard My Voice... (FULL MOVIE): the same problem of holding attention over feature length. And for Crazz I edit day-count survival videos in 99 Nights in the Forest, such as Surviving 99 Nights But The PELT TRADER is OWNER!, where the counter and the stakes carry the video. The Minecraft 100 days page and the 100 days challenge page cover how I work on these.

Minecraft 100 days editing FAQ

How long should a Minecraft 100 days video be?

Most single 100-day videos I measured on October 18, 2026 run about an hour or more. Mozi’s last 12 uploads ran 1:13:48 to 1:33:52 (median 1:26:12), and the 100-day videos on Cryptozoology and utters ran from 58:46 to 1:26:55. Episodic hardcore series run shorter episodes, and 1,000-day full movies run several hours.

How do you show the passing of days in a 100 days video?

A day counter on screen for the whole video, plus a clear marker each time the video jumps ahead (a title card or the counter ticking fast). The viewer should always know which day they are watching without being told.

Should the voiceover be recorded live or after?

In most 100-day videos the voiceover is written and recorded after the cut, because the creator knows how the story ends and can set up what matters. Live commentary still works for reactions to close calls, so keep those clips.

What is the difference between editing a 100 days video and a hardcore series?

A 100 days video is one complete story with a beginning, a middle and an end. A hardcore series is episodic: each episode needs its own goal and ending, and a recap or a reminder of the stakes at the start, because one death ends the whole world.

How do you cut 100 in-game days down to one video?

Log the recording by day, pick the moments that move the goal forward or put it at risk, and turn everything between them into short montages. Most of the in-game time ends up as montage; most of the runtime goes to the beats.
