AfterCap Help

Introducing AfterCap easily

This is a guide written so that even those not familiar with computers can read it. For detailed usage, start from Chapter 1. Take a look.

In one line,

it is a program that takes screenshots and, when you explain verbally, turns that into a document.

What kind of program is it?

Think about when you need to explain how to use a program to someone else. Usually, you do it like this:

1. Capture the screen one by one,
2. paste it into Paint,
3. open Word and move the images,
4. and type the explanation text one by one.

AfterCap changes this work like this:

1. Press the record button and, while operating the screen, explain verbally.
2. The program writes down what you say as text (automatic subtitles).
3. It organizes the recorded text and screen scenes into a document format by itself.
4. After finishing, export it as a manual, presentation material, or YouTube video.

In other words, "what you explained verbally" becomes "a document you can read".

Needed for people like this

What can be made?

• Manual — Online document (HTML), PDF
• Presentation materials — PowerPoint (PPTX)
• Word documents — DOCX
• Video — Explainer video (MP4), includes subtitles for YouTube
• Voice video — Program reads the text aloud in a video (choose machine voice)

The order in which work proceeds

(1) Screen Recording: "If you press this button..." Say this while manipulating the screen
        ↓
(2) Automatic subtitles: Transcription of what you say (on my computer without internet)
        ↓
(3) The manuscript is written and divided into chapters, with each chapter accompanied by a photo of the screen
        ↓
(4) Refine documents: Fix incorrect characters, change photos, add explanatory illustrations
        ↓
(5) Export HTML · PDF · PowerPoint · Word · Video and choose to complete it

1. Getting Started

1-1. I do this kind of work

AfterCap is Turning what is spoken and shown on the screen into a document This is a program. There are two main workbenches inside.

• Video production — A workstation for recording the screen, cutting and editing, and transcribing spoken words into subtitles
• Document creation — A workbench that assembles captures and texts into sections to create a manual

The two workbenches can be used separately, Subtitles → Script(Chapter 4) can also be continued. The moment this program's power is strongest is when you continue — because a video explained with words soon becomes a draft document.

1-2. Operating Environment

WebView2 is included by default in Windows 11so there is no need to install it separately. Most Windows 10 systems have it installed if updated, and if not, you can download it from the above link. The installer will check and guide you only when it is not present. | GPU (NVIDIA·AMD·Intel, optional) | Accelerates automatic subtitle recognition and video encoding | Works without one — just takes longer as processing is done by CPU |

The installer checks for the above two runtimes and provides download links if they are missing. However, it will not install them, so if prompted, download and install them first. For more details, Installation Guidesee here.

GPU acceleration has no separate settings to turn it on or off. Automatic subtitles use the GPU if available. Only recording/saving GPU acceleration can be adjusted inSettings.

1-3. Screen layout

The program window consists of the top common toolbar + center tabs + bottom status bar three parts.

Top common toolbar

contains tools that are shared and used across all tabs.

Select window — To capture·record Target ProgramIt's a combo where you choose.

• Section capture in document creation, and recording in video production The window chosen hereTakes a screenshot. All tabs share this selection.
• The list is The moment you perform a combo It refreshes automatically. If you don't see the program you just opened, close the combo box and open it again.
• If you select the target window, that window Even if it is hidden behind another window Capturing and recording are possible (when using the WGC engine).

Set capture window size — Adjust the target window to a set size (1280×720, 1920×1080, etc.).

• When creating a manual, if the window size is slightly different for each capture, the document will become uneven. If you adjust it once before starting All captures have a uniform sizeIt is possible.

Login — This is the button to log in to your account. When you hover the mouse over it, a tooltip will show your current account and the remaining usage period. Why login is necessary Chapter 9It is located at.

Center tab

can be adjusted inContains only values that are rarely changed once set. Values determined for each recording (size·FPS·quality, etc.) are in the video creation tab — if confused, remember: "What changes every time is in video creation, what you set once is in preferences."

Bottom status bar

Progress and results are displayed here. "Save complete: ...", "Saving frames… 3/10" Since the same message passes by, if you press a button and it seems unresponsive, first check the status bar.

Tray icon

If the program is running, there is an icon in the right tray of the taskbar. From the right-click menu Section capture · Start/stop recording etc. can be executed immediately, and global shortcuts are also displayed.

The program cannot run two instances simultaneously. If you try to run it again while already running, it brings that window to the front.

Frequently used global shortcuts

Works even when using other programs. Full list is in Appendix AIt is located at.

• JPEG quality is Image Quality Follow the settings — Normal 35 / High 55 / Highest 75.

② Decide the method to flip using mouse actions

Just before turning Automatically bring the target window to the front. Do not place other windows over the target window during capture.

③ How the capture is processed

When started, repeat the following. Do not save the same screen twiceThis is the key point.

1. Capture the current screen.
2. If the screen is empty or the same as the previous page, do not save it,and wait for the screen to change for the maximum wait time (check at 0.2-second intervals). This is a mechanism for viewers that load slowly.
3. If it changes, save it; if it does not change until the end, count it as 'No Change.' If there is no change for 6 consecutive times, consider it the last page and automatically exit.It is provided.
4. After saving, move to the next page using mouse actions and rest for the FPS interval (5fps = 0.2 seconds).

The criterion for whether to consider it an empty screen is set in Preferences → Skip Blank Pages for Each JPG Page.(Set in the settings)8-4).

④ Pause and Resume Capture

• ESC Pressing it will pause, and the start page field will be automatically set to the paused page number.A prompt saying 'Press the start recording button to continue' will appear.
• Then ● Capturewill resume capturing from that page (if the start page is 2 or higher, a confirmation window will appear once). Existing folders and files will not be deleted,and pages captured earlier will be reloaded in the filmstrip.
• If it reaches the end and exits automatically, the start page is reset to 1.It is possible.

• Section boundaries are Marker · Inserted page ＞ Silent section ＞ Set time in order. To divide at the desired place, use Frame Edit ▾ → Add Markerto mark it in advance.
• If the section you marked is long, divide it again within that section. Cutting points are ① where the screen changes and the sentence ends(where the story changes), ② pauses between paragraphs, ③ if it gets too long, at the end of a sentence. Since one section becomes one manual page, also consider the minimum length (about 200 characters · 20 seconds) so it is not cut too short.
• Exclude subtitles for the cut (removed) sections.It is possible.
• Time indication in the script [mm:ss] When the option is on, the time is attached before each paragraph.

5-8. Common Steps for Documents and Videos and Pre-Distribution Check

You can use the following functions in **Tools ▾**.

In the image editing window, Obscuremakes the corresponding part of the distributed image black pixels. For editing .scribekeeps the original, so deliver the final output externally. Image hiding is not automatically applied to linked video.

For detailed procedures, refer to 11. Creating Documents and Videos Together.

5-9. Saving

Save document Pressing the main body .scribe saves it immediately to ▾ There are two types of saving in

Ctrl+S To storage .scribe Can be saved. The saved .md is Read manuscript can be reloaded.

.scribe File is a package that contains all images used in the document (cover image, body images, overlay images)Therefore, images and directly recorded audio are stored in the file. Since only the path is saved for linked original videos, when moving to another PC, also keep the videos and reassign the path.

Devices that protect work

• Auto-save — Saves changes every 2 minutes. Without altering the original, it stacks them <Name>.scribe.autosave.scribe beside it and, if the auto-saved version is newer when opening the document, it asks which one to open.
• Save backup — Each time you save, the previous version <Name>.scribe.bak remains.
• Emergency save — If the program errors, before exiting the document is saved <Name>.recovery.scribe(or if it’s a temporary document Untitled.scribe) and the error details are saved %LocalAppData%\AfterCap\crash.log in
• Exit confirmation — If there are unsaved changes, it asks whether to save when closing.

When saving, if the line widths in the body, ASCII diagram,(┌─┐ or table drawn with the same lines are misaligned, it will notify you and, if agreed, automatically adjust them. Since Hangul is twice as wide as English, it is easy to misalign when adjusting manually.

6-4. Layout Options

• Sidebar Width — Left table of contents width (document layout only)
• Page Division — Which heading level to divide the manuscript into sections (##(H2) / ###(H3) / ####up to (H4))
• Plain Text Division — When dividing a manuscript without headings into sections, the amount per section. Automatically according to layout(About 200 characters for presentation · About 400 characters for documents) is the default, but you can choose from very short (120 characters) to very long (600 characters). It only cuts at sentence boundaries. When you change the template, documents from the manuscript will be re-divided according to the new standard (after editing, it will ask whether to save).
• Checklist Items (Checklist layout only) — The page becomes the group header, and items are extracted from the main text. Main Text List + Table(Default) / Main Text List Only / Page Title Only. Pages with nothing to extract have a single title as the item. For each item Remarks There is a box where you can write notes, and they are saved in the browser along with the check status, so they remain even when reopening the file (based on the same PC and browser).

• Split — Good for uploading to a web server. The left table of contents is included in all files, and other chapter items link to the respective files. However, full search and full print must be done for each file separately.

PDF · PowerPoint · Word 🔒

Capture image options

Applies to all four formats.

JPEG significantly reduces file size. Screen captures have a lot of flat colors, so PNG originals are already well-compressed; simply reducing size does not significantly reduce file size.

Recommended width differs by format. If reduced smaller, a warning will be shown in the window.

If you extract images as links The HTML main file becomes much smaller {File Name}_files A folder will be created together. When moving, you need to move the folder as well.

Documents and captured images before saving remain in the working folder %LocalAppData%\AfterCap Save documentIf you set the location to <Document Name>_frames the documents and images will move there along with the folder, and subsequent captures will accumulate there too (the same folder is used when reopening the document).

When the program starts, it empties this working folder. However, if a document left unsaved last time remains, it asks whether to recover it first — Choosing to recover will load that document and will not clear the folder.

Preferences can display this folder, Temporary File Cleanup empties with.CapImageThis folder contains captured images (Untitled.scribe), documents before saving (

), video preview thumbnails, temporary editing images, and WebView2 cache.VideoRecoveryVideos restored (Narration), step-by-step recordings (NarrationCache), TTS cache ( .scribe), and export task materials are also in this work root. Before cleaning, save documents .acvideoseparately and keep the linked original videos as well.

Pressing the clean button will ask for the range.

YesIf selected, you will need to log in again and re-enter the TTS API key. If there are unsaved documents, the captured images will also disappear together, so first Save documentmove them.

The recording is corrupted or fails to save in Settings → Performance · HardwareTry turning off GPU acceleration and using the CPU method.

The 'This Page' table of contents on the right is empty. It is because there is no subheading in the current section text. In the template configuration set the page division to H2. Change it, or turn off the table of contents on the right and use the main text widely.

The HTML file is too large in the export window JPEG quality 80 and Maximum width 1280 px Choosing this will reduce it significantly. To reduce it further place the image in a separate folder and select Link.

ASCII diagrams will be distorted Hangul has twice the width of English letters, so lines can easily misalign. When you save the document, it will adjust automatically. Emojis inside diagrams have inconsistent width, so it's better to exclude them.

D. Installation and Distribution

InstallSetup/AfterCap_Distribution.md — Requirements, installation order, components, upgrade/removal, creating installation files (for distribution personnel).

E. Terminology

11. Creating Documents and Videos by the Same Explanation Steps

Based on AfterCap 1.08. A separate HTML manual is provided and can be opened in a browser at docs/help/index.html. The original installation file does not include the manual

Record the target program’s usage procedure step by step, then generate manuals and training videos at the same steps. You can separately edit the document text, summary to display on the screen, and lines to read aloud

1. Manual structure and operation record

For document creation Tools → Add basic manual table of contentsCreates a template to write purpose, target version, preparations, usage procedure, expected results, and troubleshooting [Needs Writing]Replace it with the actual description. If any item is left blank, the export check will notify you

Select the target window and existing Start recordingis used. In addition to clicks, record shortcuts, text input, drag, and scroll as descriptive steps. Normal input is grouped as 'entering or editing text' instead of showing the actual characters. Since screen captures may show input content, check the image before distribution.

Select a step Tools → Add current step result screenPress this to attach the current result screen of the target window to the end of the text. It does not automatically judge the accuracy of the expected result.

2. Linking documents and videos

Select a step and open **Tools → Link descriptive step, narration, video…**

To use actual operation video, open the recording file in the video production tab and select the segment, then Link selected segment in the video production tabPress this. Currently, linking recordings and document steps is done this way. It does not include a feature to automatically link click records with recorded time.

If the original video is left empty, slides are created using captured images. You can mix the steps that connect video segments and the slide steps in a single output. The original sound of the connected video is not mixed into the composite video; instead, the specified narration or silence is used.

3. Editing step-by-step narration

Use the sequence: Record voice for this step → End recording → Preview the connected audio → Apply. You can re-record only specific steps or connect WAV, MP3, or M4A files.

TTS reuses successful results for sections where the script and voice settings are the same. Steps with changed scripts are newly generated. If synthesis fails, it retries once, and if it continues to fail, it stops the output while displaying the step number. Failures are not treated as successful silence. Video encoding is redone for the entire final file.

4. Saving and recovering work

• Documents are .scribesaved with the step ID, script, video segments, directly recorded voice, and output change status. Images are included in the usual way.
• The connected original video is .scribe not included in. When moving to another PC, bring the original videos as well and reassign the paths in the step editing.
• Video editing is saved from the project save menu of video production as .acvideo. Cuts, zoom/move, effects, subtitles, pages, markers, transitions, cropping, etc., and used images are retained.
• .acvideoThe original video is also referenced as an external file. If the original is not available when opening, select an alternative file. You need to select the original with the same content and length to match the editing position.
• The video project creates a recovery copy every 2 minutes when there are changes, and the previous file is left .bakupon saving. You can open the copy from the recovery menu.

5. Hiding distribution images

In the image editing window, ObscurePress it and place black rectangles over sensitive areas. In the final document or slide export, the black areas are composited into the image pixels. Even if the same original image is reused at another stage, the hiding will be applied.

For editing .scriberetains editable originals. Use the final export file for external distribution. It does not automatically erase sensitive sentences written directly in the main text.

Image hiding is not automatically tracked and applied to linked videos. Stages with hiding need to detach linked videos and export them to slides. For hiding in the actual video, specify the time and position in the video editor and check the entire relevant section.

6. Inspection and batch export

Tools → Pre-export production checkwill verify missing images, audio, or video, incorrect sections, uncreated table of contents, and long screen summaries. It shows the number of stages to be re-exported and whether the composition has changed for both documents and videos. This state is a comparison with the last successful export, and it does not monitor the presence or quality of export files in real-time.

**Tools → Batch export documents and videos…** to select video options and storage folder. Permission to use the existing Office export is required.

A completion folder is created after the entire task succeeds. Failed results .Incomplete_ remain in the folder and are not shown in the completion output. index.htmlLocal subtitle loading may be restricted due to browser security policies, so MP4 and separate subtitle files are also provided.

Verification scope

Automated regression tests check actual DOCX structure·image pixels, FFmpeg MP4 and video length, subtitles, saving·restoring. Input detection, multiple monitor·scaling, actual microphone devices, Word·browser screen layouts vary by program and need on-site verification. Time conversion for cut·page insertion is tested, but complex scene transition combinations should be verified on final playback.
