ArcTime - Visual Subtitle Editing and Encoding Software

---

Overview

ArcTime is a powerful and user-friendly visual subtitle creation software, supporting macOS (as well as Windows and Linux) platforms. Independently developed by Chinese developers, it aims to streamline the subtitle creation process. Through innovative "timeline dragging" and "waveform visualization" editing methods, ArcTime enables both ordinary users and professional subtitle groups to efficiently and accurately produce subtitles. Whether you're adding subtitles to personal videos, online courses, promotional videos, or cinematic works, ArcTime is an excellent choice.

Core Positioning: A Swiss Army knife-style tool that allows anyone to quickly get started and intuitively create timeline-based subtitles.

Key Features

1. Revolutionary Timeline Editing Experience

• Drag-and-Drop Timeline Matching: Completely eliminates the tedious task of manually entering timecodes frame-by-frame in traditional subtitle software. Simply drag subtitle bars on the waveform or timeline to adjust their in/out points—operations are as intuitive as video editing.
• Visual Audio Waveform: The software automatically loads the waveform of the video or audio. The peaks and troughs of the waveform clearly correspond to dialogue and sound effects, allowing you to visually pinpoint the start and end of each sentence, significantly boosting subtitle timing efficiency.

2. Powerful Text Processing and Import

• Text Import: You can directly import plain text, line-separated .txt files, or .ass/.srt files exported from software like Aegisub. The software will automatically or assistively align the text with the timeline.
• Smart Splitting: After importing long text, use the "Smart Split" feature to quickly divide the text into individual subtitle lines based on predefined rules (e.g., punctuation marks, character count).
• Multi-Encoding Recognition: Automatically identifies and handles various character encodings in .txt files (e.g., GBK, UTF-8), preventing garbled text.

3. Efficient Batch Operations and Tools

• Fast Batch Creation: Hold Cmd (macOS) to enable rapid consecutive tapping, allowing quick batch creation of subtitle bars—a core feature for efficient subtitle production.
• Timeline Adjustment Tools: Offers tools like "Timeline Pan" and "Timeline Stretch/Shrink" to globally or partially adjust subtitle timing and duration, facilitating fine-tuning or adapting to different video versions.

4. Professional-Level Subtitle Styling and Effects

• Built-in Subtitle Style Editor: No need for external software—customize font, size, color, outline, shadow, position, and other parameters directly in ArcTime, with real-time preview support.
• Multi-Track Support: Supports editing multiple subtitle tracks simultaneously (e.g., main subtitles, notes, lyrics), meeting complex subtitle needs.
• ASS/SSA Effect Tag Support: Supports common ASS/SSA effect codes, offering advanced users more customization options.

5. Extensive Format Support and Output

• Input Support: Supports importing most common video and audio formats as audio sources.
• Output Formats: Exports to widely compatible external subtitle formats like .srt, .ass/.ssa for use in any media player.
• One-Click Encoding: Features an efficient video encoding engine (based on FFmpeg) to directly hardcode subtitles into video, producing the final video file. Supports mainstream output formats (e.g., MP4) and encoders.

6. User-Friendly Features

• Auto-Save and Recovery: Prevents work loss due to unexpected crashes.
• Multi-Language Interface: Supports both Chinese and English interfaces.
• Cross-Platform Support: Provides consistent user experience across macOS, Windows, and Linux.

Advantages of ArcTime

1. Extremely Low Learning Curve: The intuitive "drag + waveform" interface allows even complete beginners to master basic operations within minutes.
2. High Production Efficiency: Compared to traditional subtitle timing tools, ArcTime improves timeline adjustment efficiency by several times, especially for dialogue-heavy videos.
3. Integrated Workflow: From text import, timeline creation, style adjustment, to final encoding output, everything is completed within a single application—no need to switch between multiple software.
4. Excellent Value for Money: Basic features are free for personal use. The paid "Pro" version offers more advanced features (e.g., additional output presets, advanced effects support) at a highly competitive price, appealing to both hobbyists and professional teams.
5. Superior Localization Experience: As a domestically developed software, it offers better support for Chinese users’ environments (e.g., fonts, encoding), with seamless communication on the official website and community.

Target Users: Video creators, content creators (UP主), online course/education professionals, language learners, subtitle group enthusiasts, and beginners in film post-production.

Conclusion: ArcTime, with its innovative design philosophy, truly makes subtitle creation simple. For users needing to efficiently complete subtitle tasks on macOS, it is a rare and excellent tool that achieves a perfect balance between usability, functionality, and efficiency.
