Using Existing SRT Subtitles and Vocal/BGM Files

If you already have translated SRT subtitles or separated vocal/background audio files, you can import them directly, skipping the software's automatic generation steps.

1. Importing Existing SRT Subtitles

Prerequisites

1. Standardize filenames: The underlying tools have limited compatibility with Chinese characters, spaces, and special symbols. It is recommended to rename video files using simple English letters, numbers, and underscores (e.g., myvideo.mp4).

2. Enable file extension display:

   • Windows 10: Open folder → click "View" → check "File name extensions"
   • Windows 11: Open folder → click "View" → "Show" → check "File name extensions"

Step-by-Step Instructions

Assuming the video file is named myvideo.mp4 and you want to translate from English to Chinese.

Step 1: Create a folder named _video_out in the same directory as the video file.

Step 2: Inside _video_out, create a subfolder named after the video with the format extension:

_video_out/myvideo-mp4/

⚠️ Version 3.87 and later require the format extension. The format is [filename]-[video format], e.g., myvideo-mp4 or video1-avi.

Step 3: Copy the two subtitle files into the subfolder and rename them using standard language codes:

_video_out/myvideo-mp4/en.srt      ← Source language subtitle (English)
_video_out/myvideo-mp4/zh-cn.srt   ← Target language subtitle (Chinese)

Step 4: Return to the main interface, import the video, and run translation. The software will detect the corresponding subtitles in _video_out and skip the ASR and translation stages, proceeding directly to dubbing and compositing.

2. Importing External Vocal and Background Audio

Since the software's built-in vocal separation uses CPU-only computation and is very slow, it is recommended to use professional third-party tools (such as UVR5-GUI) for GPU-accelerated separation:

Step 1: Use a third-party tool to separate the audio into:

• Vocal file: voice without background music
• Instrumental file: background music without voice

Output format must be wav.

Step 2: Rename the files:

vocal.wav       ← Vocal
instrument.wav  ← Instrumental

Step 3: Copy both files into the _video_out/myvideo-mp4/ folder.

Step 4: The software will directly read these files when processing the video, significantly improving recognition accuracy and saving separation time.
