I built a tool that narrates PowerPoint slides in your cloned voice. Launching it today, keeping it small for a week to fix what breaks. I just got into my College holidays a few weeks ago and I spent the last 6 weeks building Moduvox . You upload a PPTX deck, record 30 seconds of your voice, and it generates per-slide narration audio with a shareable link and viewer analytics. The idea came from a friend manually record voiceovers for training decks. Every update meant re-recording whole

Hiya! So I've been playing around with having Claude make videos for a bit now even had some success posting the results to TikTok (and setup a whole pipeline so Claude can generate and post autonomously). With the release of Nano Banana 2 Lite, I was curious show fast I could make the generation, so last night I gave it a whirl and got down to around 30s for short-form video. It uses GLM-5.2 fast via Fireworks to generate the scripts and image prompts and, like I said, Nano Banana 2 Lite for the images, gpt-4o-mini-tts for the narration, and ffmpeg to string it all together and add the Ken Burns zoom effect (which still has a shake I haven't been able to get rid of). The video compilation proved to be the blocker once the rest was in place, but I was able to speed that up by putting it on a 64 vCPU EC2. The cost might be the most interesting aspect as the short form videos tend to be about 25 cents. Almost 90% of that is the images, which are 3.336 cents a piece. Of course, running

最近对网站进行了重构，做成了免费的视频工具站：[ArtPlayer Tools]( https://artplayer.org/tools/) 主要是围绕着 ffmpeg.wasm 和 mediabunny 实现的一些可以直接在浏览器里用的视频/音频工具，常用的有： - 视频压缩：[Compress Video]( https://artplayer.org/compress-video/) - 视频裁剪：[Crop Video]( https://artplayer.org/crop-video/) - 视频合并：[Merge Video]( https://artplayer.org/merge-video/) - 视频尺寸调整：[Resize Video]( https://artplayer.org/resize-video/) - 视频旋转：[Rotate Video]( https://artplayer.org/rotate-video/) - 视频调速：[Change Video Speed]( https://artplayer.org/change-video-speed/) - 添加文字到视频：[Add Text to Video]( https://artplayer.org/add-text-to-video/) - 添加水印：[Watermark Video]( https://artplayer.org/watermark-video/) - 提取字幕：[Subtitle Editor]( https://artplayer.org/subtitle-editor/) - HLS 转 MP4：[HLS to MP4]( https://artplayer.org/hls-to-mp4/) - 音频可视化：[Audio Visualizer]( https://artplayer.org/audio-visualizer/) 大部分工具都是本地处理，文件不会上传到服务器。最开始是因为自己偶尔要处理一些视频，开剪辑软件又有点重，在线工具又担心隐私，所以就慢慢做成了一个站。 目前还在持续完善，体验肯定还有不少粗糙的地方，比如不同浏览器的兼容、移动端操作、长视频性能之类的。 网站： [ArtPlayer Tools]( https:
