选几段视频Pick your videos
从相册或「文件」里选同一支舞的 1 到 6 段视频。谁拍的、从哪开始、拍了多长都行，只要录到了音乐。Choose 1 to 6 videos of the same dance from Photos or Files. Any phone, any start, any length, as long as the music is in it.
-
点「开始接龙」Tap Start
视频按音乐自动对齐，再自动比较每一段的动作和人数，挑出最好看的那个视频，切换点放在动作停顿的瞬间。The videos line up by the music. DanceChain compares the moves and dancers in every part, picks the best video, and switches on a still moment.
-
保存、分享Save and share
成片保存到相册，或直接发给舞友。想改？拖一拖切换点、换一段视频，几秒钟重新导出。Save the film to Photos or send it to the group. Want a change? Drag a switch point or swap a part, and re-export in seconds.
为什么不是剪辑软件Why not an editing app
剪辑软件让你自己剪，舞接龙替你剪好Editing apps hand you the tools. DanceChain hands you the film.
自动挑精彩Best moments
每一段，都用最好看的那个镜头Every part gets its best shot
舞接龙会自动比较每段视频：动作是否舒展、画面里有几个人，再决定这一段用谁拍的。切换点自动放在动作停顿的瞬间，接得自然，看不出拼接。DanceChain compares every video for you: how full the movement is and how many dancers are in frame. Then it decides whose video each part should use. Switches land on a still moment, so the joins feel natural.
- 成片上标出每一段用了哪个视频、为什么See which video each part uses, and why
- 也可以选「轮流接力」：每个视频轮流跳一段Or choose Take Turns: every video takes an equal turn
- 全部在手机上完成，视频不上传It all happens on your phone; nothing is uploaded

3精彩度Highlight score
原曲Original song
说话声、数拍子，统统换成原曲Swap the room noise for the real song
排练时总有人说话、数拍子，手机录的音乐也不清楚。加上这首歌的音乐文件，舞接龙自动找到对应的位置，用干净的原曲代替现场声音，整首不断、不跳。Rehearsal recordings come with chatter, counting and tinny music. Add the song file and DanceChain finds exactly where it lines up, then uses the clean track for the whole film. No gaps, no jumps.
- mp3、m4a 等常见格式都可以，也能用视频文件里的音乐MP3, M4A and other common formats, or the music from a video file
- 没有原曲也行：自动用音质最好的那段录音No song file? It uses the clearest recording among your videos
还有And also
细节，都替你想好了The details are taken care of
手动微调Fine-tune by hand
拖动切换点、给某一段换个视频、分成两段或并入旁边的一段，重新导出只要几秒。Drag switch points, use a different video for any part, split a part or merge it into its neighbour. Re-export takes seconds.
不同手机都能接Any phone, any shape
不同手机、横拍竖拍、不同画质，自动统一画面大小和色彩，接起来像一台机器拍的。Different phones, portrait or landscape, different quality. Size and colour are evened out so it looks like one camera.

四种转场（闪白、淡入淡出、直切、推入），整片调亮调暗，加一行歌名或队名放在画面任何位置，还能加一个宣纸毛笔字的片头。Four handoff styles (flash, fade, cut, push), brighten or darken the whole film, a caption — the song or your group's name — anywhere you drag it, a brush-calligraphy title card on rice paper.
拍到了别的视频？Other clips in the mix?
谢幕、合影、另一首歌：舞接龙会问你放在开头还是最后，或者全部按顺序接起来。A bow, a group photo, another song: DanceChain asks whether to put them first or last, or simply play everything in order.

FAQ
常见问题Questions
需要什么样的视频？What videos do I need?
同一支舞、同一首歌的 1 到 6 段视频，录到了音乐就行。开拍早晚、长短都没关系，也可以只拍了其中一部分。1 to 6 videos of the same dance to the same song, with the music audible. Start times and lengths can differ, and a video can cover just part of the song.
会上传我的视频吗？Are my videos uploaded?
不会。所有处理都在你的手机上完成，我们看不到你的视频。No. Everything happens on your phone. We never see your videos.
怎么加原曲 / 背景音乐？How do I add the original song?
在首页「原曲」里选这首歌的音乐文件（mp3、m4a、wav 等，也可以是一段带这首歌的视频）。舞接龙会自动找到它和视频对应的位置，用干净的原曲代替现场的说话声和数拍子。文件可以放在「文件」App、iCloud 云盘或微信里（微信里长按文件 → 用其他应用打开 → 存到文件）。On the home screen, tap Original Song and pick the song's audio file (MP3, M4A, WAV…, or a video that contains the song). DanceChain finds where it lines up with your videos and uses the clean track instead of the room noise. The file can come from the Files app, iCloud Drive or a chat app (save it to Files first).
原曲对不上怎么办？The song doesn't line up — what now?
对不上通常是因为不是同一个版本（现场放的是伴奏版、加速版或别的歌手唱的）。换成现场实际播放的那个版本就好。如果没有原曲文件，不加也行：舞接龙会用你的视频里录音最清楚的那段。Usually it's a different version of the song (an instrumental, a sped-up edit, another singer). Use the exact version that was played in the room. No song file? Just skip it: DanceChain uses the clearest recording among your videos.
安卓手机能用吗？Is there an Android version?
目前只有 iPhone 版，需要 iOS 18 或更新的系统。Not yet. DanceChain is for iPhone, on iOS 18 or later.
下次排练，多拍几段Next rehearsal, film it a few times
