How to edit a long broadcast and entrust the entire 8-hour replay

Replaying an 8-hour broadcast from the beginning to edit it is a battle you can't win. The bottleneck in editing long broadcasts is not the cutting technique, but the time it takes to find sections to write, and this time is honestly proportional to the length of the broadcast. So the longer the broadcast, the more the order needs to be reversed. The structure is such that AI scans the entire process to create candidates, and humans only inspect them.

Why does editing a long broadcast take longer than broadcasting?

The real reason editing long broadcasts is difficult is not cutting, but finding. The search time increases in proportion to the length of the broadcast and has nothing to do with editing skills. If it is a 2-hour broadcast, you can do anything by just remembering and replaying a few parts. After 8 hours, the method itself falls apart.

Immediately after the broadcast, you end up putting off editing because you're exhausted, and while you're putting it off, your memories become blurry. If you start to get confused about what time zone “that scene” was, you end up wasting time going back and forth between replays to find it. If you are on a platform that has a set replay storage period like Chzzk or SOOP], there is a risk that the video will disappear while you postpone it.

8 hours of broadcast, how long will it take just to look through it?

You can get the answer just by doing a simple calculation. 8 hours is 480 minutes. It takes 240 minutes to watch at 2x speed, and 120 minutes to scrub at 4x speed, which is virtually impossible.

1x speed continuous driving480

2x speed watching240

4x speed scrub120

This value only calculates the scanning time. After deciding on a section, there is separate time to refine the front and back, add subtitles, and create a title. For a channel that broadcasts long broadcasts two to three times a week, it is difficult to consistently upload shorts with this structure. What signal to select for highlights is separately summarized in Broadcast Highlight Editing Guide.

4 ways to edit long broadcasts, what are the differences?

A sense of cost when outsourcing is covered in Summary of Short Form Editing Outsourcing Prices], and how to convert tool fees to broadcast length is covered in Comparing Prices of AI Shorts Production Programs]. If the replay of SOOP is uploaded in multiple parts, please refer to Summary of SOOP replay highlights. Whether outsourcing or AI, the core is the same. Editing long broadcasts becomes sustainable only when the step of finding sections to write is taken out of human hands.

Check before leaving everything to AI

Even with the same “AI editing,” the ability to handle long broadcasts is great for each tool. Please check this before transferring.

• ✅ Will I receive a replay link right away or will it only be uploaded as a file?
• ✅ What is the maximum length of time that can be analyzed at once (8 hours is cut in the middle)?
• ✅ Is there a basis for selecting the highlight? (Can you confirm why it is this section?)
• ✅ Do the subtitles hold up in the Korean broadcast tone?
• ✅ Vertical shorts, horizontal clips, subtitles, and titles all displayed at once?

ClipSpray is a service created to meet this standard. If you just post a link to replay Chzzk and SOOP, the points where chat was concentrated and the points where cheese and star balloons exploded are read together to select editing points, and even cut edits, subtitles, and vertical shorts are organized into one report. Broadcasts are analyzed from beginning to end, and the Free and Light plans receive 8 hours per video, while the Pro and Max plans receive unlimited length.

The actual sequence of turning an 8-hour replay into shorts

1️⃣ After the broadcast ends, we will secure a replay link. After the storage period, the material itself disappears.

2️⃣ Put it entirely in AI analysis and do something else. In long broadcast edits, this is not the stage where people need to wait.

3️⃣ Review the candidate list with evidence. There is no need to watch the broadcast again because you only need to check why the chat was crowded and whether the context was cut off.

4️⃣ Start with clear vertical shorts, and only expand with horizontal clips for materials that respond well. Shorts can also receive revenue distribution based on views through the YouTube Partner Program, so it is advantageous to accumulate it steadily.

5️⃣ Organize the title and upload phrase. If the tool comes up to this step automatically, you'll have less work to do.

Tip: When reviewing, look first at “Can someone who hasn’t watched the broadcast understand it?” rather than “Is this clip funny?” Highlights of long broadcasts can easily lose context, so they can often be revived by just pulling back the starting point by a few seconds.

Frequently Asked Questions

Are broadcasts longer than 8 hours analyzed at once?

Each tool takes a different length at a time. Based on ClipSpray, the Free and Light plans analyze up to 8 hours per video, and the Pro plan analyzes with no length limit.

Would it be better to separate the overnight broadcasts?

If the replay is already split into several parts, it is easier to manage it if you upload them individually. If it is a very long video that is connected as one, it is better to analyze the entire video using a plan with no length limit so that you do not miss the flow of the broadcast.

Is it effective even though it is focused on low-chat rather than game broadcasts?

In low-chat and talk broadcasts, there are few changes on the screen, making it more difficult to look through them. If you use chat speed and sponsorship response as signals, you can catch quiet sections that are not visible just by looking at the screen.

What should I do before the replay is deleted?

Each platform has a replay storage period, so secure the link to the broadcast you want to edit in advance and back up the original if necessary. There is no way to retrieve highlights from deleted broadcasts.
