Background Volume Multiplier: The background audio volume is multiplied by this value. For example, if you enter 0.8, the volume is reduced to 80% of the original.
Loop Background Sound: If the background audio is shorter than the video, whether to repeat the background audio. true for looping, false for not looping.
302.ai Translation Model List: Enter the names of the models used by 302.ai for translation, separated by English commas.

ByteDance Volcano Inference Endpoint: Fill in the name of the inference endpoint created in ByteDance Volcano Ark. See https://pyvideotrans.com/zijiehuoshan for how to create it.
Video Transcoding Loss Control: Loss control during video transcoding. 0 = lowest loss, 51 = highest loss, default 13.
NVIDIA Use qp Instead of crf: Whether to use qp instead of crf to control video quality loss on NVIDIA graphics cards. true = yes, false = no.
Output Video Quality Control: Used to control the output video quality and size. Faster speed means lower quality.
Custom ffmpeg Command Parameters: Custom ffmpeg command parameters, which will be added in the second to last position. For example: -bf 7 -b_ref_mode middle
264 or 265 Video Encoding: Enter 264 to use libx264 encoding, and enter 265 to use libx265 encoding. 264 has better compatibility, and 265 has a larger compression ratio and higher definition.
Audio Maximum Acceleration Multiple: The maximum acceleration multiple of the audio. The default is 3, which means the maximum acceleration is 3 times the original speed. It needs to be set to a number between 1-100. For example, 3 means a maximum acceleration of 3 times. Used to control the duration of the voice-over to be aligned with the original duration.
Video Slow Motion Multiple: Video slow motion multiple: a number greater than 1, representing the maximum allowable slow motion multiple. 0 or 1 means no video slow motion, used to extend the video to align with the voice-over and subtitles.
Remove Voice-over Trailing Silence: Whether to remove the silent space at the end of the voice-over. true = remove, false = do not remove.
Remove Subtitle Duration Greater Than Voice-over Duration: Whether to remove silence when the original subtitle duration is greater than the voice-over duration. For example, if the original duration is 5s and the voice-over is 3s, whether to remove the 2s silence. true = remove, false = do not remove.
Remove Silence Length Between 2 Subtitles: Remove the silence length between 2 subtitles in ms. For example, 100ms, that is, if the interval between two subtitles is greater than 100ms, 100ms will be removed. -1 = completely remove.
Force Modify Subtitle Timeline: true = force modify subtitle timeline to match the sound, false = do not modify, keep the original subtitle timeline. Not modifying may cause the subtitles and sound to be mismatched.
Enable VAD: Enable VAD in faster-whisper subtitle overall recognition mode. true = enable, false = disable. Enabled by default.
Minimum Silent Segment: Minimum silent segment ms, default 250ms.
Maximum Sentence Duration Seconds: Maximum sentence duration seconds, default 6s.
VAD Threshold: VAD threshold
VAD Pad Value: VAD pad value
Equal Division Silent Segment: Silent segment in equal division mode, default 10s
Equal Division Segment Duration: Duration of each segment in equal division mode in seconds.
faster and openai Model List: Model name list under faster mode and openai mode, separated by English commas.
CUDA Data Type: cuda data type in faster mode, int8 = less resource consumption, fast speed, low precision, float32 = more resource consumption, slow speed, high precision, int8_float16 = device auto-select
Whisper Model Prompt: Prompt word sent to the whisper model.
faster-whisper cpu Process: In faster mode, the number of cpu processes during subtitle recognition.
faster-whisper Worker Process: In faster mode, the number of concurrent worker processes during subtitle recognition.
Subtitle Recognition Accuracy Control 1: Precision adjustment during subtitle recognition, 1-5, 1 = lowest memory consumption, 5 = highest memory consumption.
Subtitle Recognition Accuracy Control 2: Precision adjustment during subtitle recognition, 1-5, 1 = lowest memory consumption, 5 = highest memory consumption.
faster-whisper Temperature Control: 0 = occupy less GPU resources but slightly worse effect, 1 = occupy more GPU resources and better effect
Context Awareness: true = occupy more GPU with better results, false = occupy less GPU with slightly worse results.
Hard Subtitle Font Pixel: Hard subtitle font pixel size
Hard Subtitle Font Name: Font name for hard subtitles
Hard Subtitle Text Color: Set the color of the font. Note that the 6 characters after &H, each 2 letters represent the BGR color, that is, 2-bit blue / 2-bit green / 2-bit red, which is the reverse of the common RGB color.
Hard Subtitle Text Border Color: Set the font border color. Note that the 6 characters after &H, each 2 letters represent the BGR color, that is, 2-bit blue / 2-bit green / 2-bit red, which is the reverse of the common RGB color.
Hard Subtitle Move Up Distance: The subtitles are located at the bottom of the video by default. Here you can set a value greater than 0, representing the distance the subtitles move up. Note that the maximum should not be greater than (video height - 20), that is, at least 20 height should be reserved for display. Subtitles, otherwise subtitles will not be visible
faster/openai-whisper Re-punctuate After Recognition: If selected, nltk will be used to re-punctuate after recognition.
