Importing and playing media

• You can select videos from Photos, import audio or video files, or open supported media from another app.
• Media-AI supports system playback formats and uses an additional playback engine for formats such as MKV, WebM, and AVI when needed.
• If a file does not open, confirm that it is fully downloaded, not protected by DRM, and uses supported audio and video codecs.

Generating AI subtitles

• AI transcription runs on your device with the bundled Whisper model and may use substantial memory, storage, battery, and processing time.
• Keep the app available while the task prepares audio and processes chunks. You can review task status from the Tasks tab.
• For better results, choose the spoken language when known and use clean, clearly audible speech.
• Completed subtitles can be displayed, translated, adjusted, and exported from the player.

Recording and live transcription

• Microphone permission is required before Media-AI can record audio.
• The large AI model must be ready before recording and live transcription begin.
• Headphones can help prevent playback audio from being captured again by the microphone.
• If transcription stops, check microphone permission, available storage, and whether another app is using the audio input.

Subtitle translation

• Translation uses Apple's system Translation framework rather than a Media-AI server.
• The required language model may need to be downloaded by the operating system.
• Translation availability depends on the device, OS version, selected source language, and target language.

WebDAV, SMB, podcasts, and media links

• Local network permission is needed for SMB and other sources hosted on your local network.
• Check the host, port, path, username, password, and TLS setting when a saved connection fails.
• Remote playback and podcast feeds require network access and depend on the availability and compatibility of the server you choose.
• Media-AI stores saved connection passwords in the device Keychain.

Storage, cache, and deletion

• Open Settings → Storage Management to review app-managed media, subtitles, transcription work files, and caches.
• Deleting generated subtitles does not delete the original media file unless you separately remove that media from the local library.
• Removing a saved network connection or podcast subscription does not delete content from the remote server.
• Some temporary data is normally cleared after a task finishes or expires.

When contacting support, do not send private recordings, full network credentials, or unredacted personal media. A short sample or redacted screenshot is usually enough.

导入与播放媒体

• 你可以从照片图库选择视频、导入音视频文件，或从其他应用打开受支持的媒体。
• Media-AI 优先使用系统播放器，并在需要时通过附加播放引擎支持 MKV、WebM、AVI 等格式。
• 如果文件无法打开，请确认文件已完整下载、没有 DRM 保护，且音视频编码受到支持。

生成 AI 字幕

• AI 转写通过内置 Whisper 模型在设备端运行，可能占用较多内存、存储、电量和处理时间。
• 应用准备音频并分块处理时，请保持任务可运行；你可以在“任务”页查看状态。
• 已知语音语言时建议明确选择，并尽量使用人声清晰、背景噪声较少的媒体。
• 已完成字幕可在播放器中显示、翻译、调整和导出。

录音与实时转写

• 开始录音前需要授予麦克风权限。
• 大模型准备完成后才能开始录音和实时转写。
• 使用耳机可以减少播放声音被麦克风再次录入的情况。
• 如果转写停止，请检查麦克风权限、可用存储空间，以及是否有其他应用正在占用音频输入。

字幕翻译

• 翻译使用 Apple 系统 Translation framework，不经过 Media-AI 自有服务器。
• 系统可能需要先下载对应语言模型。
• 翻译是否可用取决于设备、系统版本、源语言和目标语言。

WebDAV、SMB、播客与媒体链接

• 访问 SMB 或局域网内的其他媒体源需要本地网络权限。
• 连接失败时请检查主机、端口、路径、用户名、密码及 TLS 设置。
• 远程播放和播客订阅需要网络连接，并依赖你所选服务器的可用性与兼容性。
• Media-AI 会将已保存连接的密码存放在设备钥匙串中。

存储、缓存与删除

• 在“设置 → 存储管理”中可查看应用管理的媒体、字幕、转写工作文件和缓存。
• 删除生成的字幕不会删除原始媒体；如需删除媒体，请在本地媒体库中另行操作。
• 删除网络连接或播客订阅不会删除远程服务器上的内容。
• 部分临时数据通常会在任务完成或过期后清理。

联系支持时，请勿发送私人录音、完整网络凭据或未打码的个人媒体。通常提供短样本或已打码截图即可。
