Virtuber Shorts Edit: How to find broken sections in broadcasts where the screen doesn't change

The reason that editing VTuber shorts is particularly difficult is not a problem with editing skills. This is because the model remains in the same position and the background does not change, so the method of looking at the screen to find the burst section itself does not work. Wherever the reaction comes from, it remains in chat and sponsorship, not on the screen.

Why doesn’t auto-editing work on Virtuber broadcasts?

If you are trying to find highlights from a Virtuber broadcast on the screen, there are very few clues you can use. This is because the model and background are fixed, so there is no signal of a scene change at all.

When a game is broadcast using a live-action cam, the expression and body shake significantly at the moment of surprise, and the game screen also changes rapidly. Virtuber has little information on this. Since the Live2D model's mouth, eyes, and upper body only move within a certain range, the pixel difference between the moment of being very surprised and the moment of quietly playing the game is smaller than expected.

If it is a 3D model or full tracking, the movement is a little more vivid. Still, the camera cut remains the same. This is why the results come out flat when you add the Virtuber replay to a tool that uses screen changes as a standard.

If you read the table vertically, you can immediately see what signals are remaining in the Virtuber broadcast. Sound, chat, and support.

Why are chatting and sponsorships more accurate in Virtuber broadcasts?

The point where the chat speed jumps and the timing of the sponsorship are edited points taken by the viewer. Even if the screen is quiet, the reaction is honest, so the value of these two things increases in broadcasts with thinner screen signals.

If it is Chzzk, the time when the cheese was inserted, and if it is SOOP, the time when the star balloon and ad balloon arrived] remain as a timestamp. Even if you miss it because you're busy during the broadcast, the record still remains.

Chat should be read a little differently. The signal is how many lines are uploaded per second rather than the content of individual sentences and whether the same words are plastered all over the place. Sections where expressions of laughter pour out or certain memes are suddenly repeated are usually places where something has exploded.

Tip: Consider separately whether you want to include the sponsorship notification itself in the clip. It is natural to use the sponsorship time as a clue to find the section, and move the actual clip start point forward about 20 to 40 seconds before the sponsorship comes in. Because the reaction comes later than the event.

However, not all chats are highlights. There are a few designated spots where it is easy to miss.

• Personnel plastered right after the broadcast started: This is not an incident caused by crowding of people.
• Regular sponsorship or subscription renewal notification: Only the time is recorded regardless of the broadcast content.
• Notice or event information section: The chat explodes, but if you cut it to a clip, there is no context.
• Reaction after a long silence: The incident ended 30 seconds ago and only the chat followed later.

Even if you filter out just these four things when inspecting, the accuracy of the candidate list increases considerably. If you want to take a closer look at the signal itself for selecting highlights, we have organized them by type in Broadcast Highlight Editing Guide.

How do I set the vertical screen differently for that chat and game broadcast?

If you crop a horizontal broadcast to 9:16, more than half of the screen disappears. The Virtuber layout usually has the game screen in the middle, the model in one corner, and notifications and chat windows at the edges, so if you push it vertically, it will look awkward no matter what you do.

The reason why you need to enlarge the subtitles in that chat clip is simple. Since the only thing to see on the screen is the model, the only information viewers can grab is the subtitles. Conversely, filling up subtitles in a game broadcast clip obscures the actual game situation.

• ✅ Is the model’s face within the vertical frame?
• ✅ Can someone who has not watched the broadcast understand the game situation?
• ✅ Is the chat window or notification overlay cut off awkwardly?
• ✅ Do the subtitles cover the model’s mouth or game information?
• ✅ Is the situation revealed within the first 2 seconds?

Where are the subtitles on Virtuber broadcasts most likely to be wrong?

The accuracy of automatic subtitles is useful in everyday conversations, but it falls apart in certain places in Virtuber broadcasts. This is because there are many words that do not exist in the dictionary. Character names, memes used only on the channel, and viewer titles are not learned words, so they are replaced with strange words with similar pronunciations.

If you try to fix everything, the time will increase again. You only need to look at the subtitles for the 20 to 40 second section of the clip, and most of them will be filtered out by just checking the five positions above.

Note: Once you create a list of proper nouns, you will continue to use it. The longer you run the channel, the more new memes you have to add, so taking 30 minutes to organize them in the beginning reduces the weekly review time.

What criteria should a channel that broadcasts every day choose a tool for?

You have to look at the broadcast length first. For a channel that broadcasts 5 to 9 hours a day, 5 days a week, the number of replays accumulated per month exceeds 20. If the length of video that the tool accepts at once is 8 hours, the overnight broadcast is cut off in the middle, and if the monthly processing limit is low, even if there is material left, it cannot be processed.

ClipSpray receives the Chzzk and SOOP replay links as is, reads the points where chat was concentrated, the timing of sponsorship, and voice changes, and organizes cut edits, subtitles, and vertical short forms into a single report. If the replay is private or has already been taken down, you can upload the original recording file. Free and Light analyze up to 8 hours per video, while Pro and Max analyze without length limit.

Broadcasting 5 days a week means broadcasting over 20 times a month, so if you want to pull out a report for each broadcast, Pro's 16 is not enough. This means that there is no reason to use the same plan for channels you turn on every day and channels you turn on twice a week. Conditions for each plan are summarized in Plan page], and what signals are read from Virtuber broadcasts are summarized in Virtuber editing automation guide.

What is the overall order when subscribing to a long broadcast in its entirety was discussed separately in How to Submit an Entire 8-Hour Replay].

Actual order when a VTuber channel rolls shorts

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

2️⃣ Put the whole thing into analysis and sleep. There is no reason for anyone to be attached at this stage.

3️⃣ Review the candidates with evidence. There is no need to watch the broadcast again because you only need to check why the chat was crowded.

4️⃣ Check the framing of the vertical clip. See if the model is alive and if the game situation is understood.

5️⃣ Correct proper nouns in subtitles. Character names, channel memes, and viewer titles are places where automatic subtitles often make mistakes.

6️⃣ I’ll start by uploading things that are clear. Shorts also receive revenue distribution based on views through the YouTube Partner Program, so it is advantageous to accumulate it steadily.

Caution: If you upload automatic subtitles as is, it will be especially noticeable on Virtuber channels. If a character's name is changed to an incorrect word, regular viewers will notice first, and the clip will not be able to leave the channel. To save review time, make a separate list of frequently incorrect proper nouns and check the same place each time.

Frequently Asked Questions

Are highlights automatically captured in Virtuber broadcasts?

Tools that use screen changes as signals may be weak. This is because the model and background are fixed, so the pixel difference is not large. A tool that reads both chat speed and sponsorship timing can find sections where responses are strong even when the screen is quiet.

Since it is mainly for that chat, there is no game screen. Can I use it?

That chat is actually a type that is more difficult to scan with the eye. Because it's the same screen for hours on end, there's no reference point to find by rewinding. Since this is a broadcast where words are the highlight, it is better to review based on chat reactions and voice changes, and prioritize subtitle quality.

Is your 2D model cut off on a vertical screen?

If you cut the horizontal broadcast to 9:16, the model and one of the game screens will be pushed off the screen. Before uploading the automatic conversion results, check with your own eyes that the model's face is alive and that you understand the game situation.

It broadcasts for 8 hours a day. Can it be analyzed all 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 and Max plans analyze without any length limit.

I'm working on my own without an agency. Can I publish the shorts without an editor?

This can be done by taking the step of finding a section to write out of your hands. The sticking point without an editor is usually not the cutting technique, but the time it takes to choose which scenes to use in long replays.
