EasyVideo Studio — Updated November 14, 2026

OPENING THE APP
Upload the entire contents of this ZIP to your Cloudflare Pages project, with index.html at the top level. Open its HTTPS address in desktop Chrome on your Chromebook or PC. Do not open index.html by double clicking it: the MP4 engine needs the included files served by a website. Keep the engine folder and all three core-part files together. No API keys or subscriptions are required by this app.

RECORD A PODCAST SHOWING YOUR PC
1. Click Podcast / Screen Recorder.
2. Click Show my PC screen. In Chrome's own chooser, select a screen, window, or tab and click Share. The app cannot bypass this chooser.
3. Confirm that the shared screen appears in the preview. To avoid the repeated mirror effect, share a different tab/window or minimize the studio while recording.
4. Leave Microphone checked for your voice. Check Show my camera for a face-in-corner overlay. Choose its corner. You can turn the camera off and on during recording.
5. Click Start recording. Allow microphone access. If access fails, recording will not silently continue without your requested microphone.
6. Click Stop, save & edit. The recording appears in Your finished video below the editor, ready to preview and download, and is also added as a scene.
7. Download the original. If it is WebM, click Download as MP4 for conversion. Your original remains available if conversion fails.
Shared audio depends on Chrome and your operating system. For website sound, share a Chrome tab and enable Also share tab audio. Use headphones to avoid speaker echo. Screen sharing requires desktop Chrome; mobile screen capture is not supported by this app.

CREATE VIDEOS FROM PHOTOS
Click Videos & photos, select photos, and arrange the scenes with Move left / Move right. Set each photo's length, title, effect, and motion. Add background audio with Music / voice-over. Added audio loops to fit the timeline; Remove audio removes it. Choose landscape, vertical, or square. Play to preview, then Export video. Export records in real time. Keep this tab visible. Use Download as MP4 if the original export is WebM.

MAKE AN MP4 FROM AN MP3
Click MP3 / audio to MP4. Choose your MP3 (or another supported audio file), an optional cover photo, and a title. Click Create & download MP4. The result is a video with the cover image and full audio. This direct converter does not loop your audio. For animated photos with music, use the photo editor instead.

CONVERT AN EXISTING VIDEO
Click Convert video to MP4, choose a video, then Convert & download MP4. The output uses H.264 video and AAC audio. Conversion runs locally and may be slow for large videos or on low-memory devices. Keep the page open. The engine files are bundled, so no third-party CDN is needed.

SPEECH TO TEXT
Click Speech to text, Start listening, and allow the microphone. Speak, then Stop listening. Review/edit the transcript and click Download text. Download captions creates SRT with approximate timings from the live dictation session. Caption text retains the original recognition; edits apply to the text download. Live dictation may use Chrome's online speech service. This feature transcribes live microphone speech, not uploaded MP3/video files. Dictation is a separate tool; closing its dialog stops listening. Long pauses may end a recognition session; click Start listening again to append more words. Transcript text is saved locally in this browser; download it for a permanent copy. Clear transcript removes the saved text.

SAVE YOUR WORK
Save project downloads a JSON containing your media and edits. Open project restores it. Finished videos and project files are separate. Keep a downloaded copy before closing or refreshing. Recordings are held in memory until downloaded; long high-resolution sessions require sufficient device memory. This is a local recording/editor tool, not a livestream or remote-guest call service.

VERIFICATION
The bundled WebAssembly engine was run on a test MP3 and its output was verified as H.264/AAC MP4 with the expected 2-second duration. Video-to-MP4 conversion was also exercised with the same engine. Application logic tests used simulated browser/media APIs for photo import, scene edits, export completion, project save, live recognition callbacks, transcript/caption downloads, screen+microphone mixing, microphone mute, recording stop/cleanup, and microphone denial.
A full browser launch was blocked by the test workspace's browser restrictions. Real screen selection, webcam/microphone hardware, live speech accuracy, and device-specific downloads still need a short trial on your own PC. They are not claimed as hardware-tested.
