22 local media tools for video, audio, images, captions, and saved workflows
A desktop media toolkit with 22 tools for video, audio, and images. Edit captions, clean up speech, save processing workflows, and keep track of every export. Your media stays on your machine. No subscriptions or accounts.
Editing media shouldn't require expensive subscriptions, complex software, or uploading files to the cloud. You just need to trim a video, compress a clip, or convert a format. It should be simple.
DC Studio puts 22 media tools in one app. Processing runs locally, including AI transcription after its speech model is downloaded. Pick a tool for a quick edit, or save a workflow for tasks you repeat.

4 platforms available. Select your platform above.
DC Studio processes all media locally using a bundled FFmpeg build. Your files never leave your device. No cloud upload, no account, no telemetry.
Video Trimmer
Choose start and end times with a visual timeline and waveform. Stream-copy exports follow source keyframes, which can affect cut boundaries.
Video Splitter
Split by duration, equal parts, or custom points. Export segments to a chosen folder with names that avoid existing files.
Video Merge
Combine clips with drag-to-reorder. Mixed sizes and timing are normalized, and audio is preserved when some clips are silent.
Video Compressor
Reduce video file size with quality presets or target a specific file size. Supports multiple output formats.
Video Rotate
Rotate videos 90°, 180°, or 270° and flip horizontally or vertically. Preview the orientation before export.
Video Watermark
Add text or image watermarks to videos with adjustable position, opacity, and size controls.
Speed Changer
Speed up or slow down video and audio from 0.25x to 4x. Option to maintain audio pitch.
Video to GIF
Convert video clips to animated GIFs with control over frame rate, resolution, and quality.
Media Converter
Convert between video, audio, and image formats. Supports MP4, MOV, AVI, MP3, WAV, PNG, JPG, and more.
Auto Subtitles
Transcribe speech locally with Whisper, then search and correct caption text and timing. Download a speech model once to use transcription offline.
Caption Import & Export
Import or export SRT and VTT files. Add a selectable subtitle track to MP4, or burn styled captions into the video.
Media Tracks
Inspect audio and subtitle tracks, choose what to keep, remove audio, or replace it with explicit controls for mismatched durations.
Batch Processing
Apply convert, compress, resize, audio extract, watermark, rotate, or speed change settings to many files with per-file progress.
Saved Workflows
Connect supported operations into a saved sequence. Process multiple files and pass each step's output to the next automatically.
Watch Folders
Enable a saved workflow for a folder while the app is open. Wait for stable files, skip previous results, and review or retry each file.
Social Media Presets
One-click output sizing for Instagram Reels, TikTok, YouTube Shorts, Instagram Feed, YouTube, and X, in fill or fit modes.
Thumbnail Generator
Save a chosen video frame as JPEG or PNG, or export a contact sheet with configurable rows, columns, and thumbnail size.
Hardware Acceleration
See the detected encoder in Settings and choose hardware or software encoding. Available hardware encoders depend on your device.
Audio Trimmer
Trim audio files with waveform display for precise start and end point selection. Export to multiple formats.
Audio Extractor
Extract audio tracks from video files. Export to MP3, WAV, FLAC, AAC, or OGG with quality selection.
Audio Normalizer
Match loudness to streaming, podcast, or broadcast targets using two-pass EBU R128 normalization.
Voice Cleanup
Reduce background noise locally, compare a short before/after preview, and optionally normalize loudness. RNNoise mode uses a model you supply.
Silence Remover
Detect silent gaps in video or audio and review them on a waveform before cutting.
Audio Speed Control
Use Speed Changer with audio files to adjust playback speed from 0.25x to 4x, with optional pitch preservation.
Image Filter
Apply adjustable filters including brightness, contrast, saturation, and blur with real-time preview.
Image Resize & Crop
Resize images by dimension or percentage with aspect ratio lock. Crop with precision controls.
Image Conversion
Convert images to another supported format with Media Converter, or resize a collection with Batch Processing.
Presets & Branding
Save, update, duplicate, or delete named processing presets, including watermark branding settings and a remembered output folder.
Persistent Export History
Keep exports visible as you move between tools. Follow progress, cancel work, retry with saved settings, and open or reveal finished files.
Send to Another Tool
Continue editing a completed export in another compatible tool directly from its history entry.
macOS & Windows
Native builds for macOS (Apple Silicon and Intel) and Windows (MSI, setup EXE, and portable mode).
Offline Processing
Video, audio, image processing, and transcription run on your machine. Your media is not uploaded.
Portable Mode
Windows portable ZIP runs without installation. Carry it on a USB drive.

Changelog
v0.5.0 · September 10, 2026
Reusable workflows, editable captions, and four new tools bring the dashboard to 22 tools.
- Presets and branding. Save, load, update, duplicate, and delete named presets, including watermark settings and remembered output folders.
- Export history. Keep progress and cancellation available when navigating between tools. Retry with saved settings, open or reveal results, and send finished files to another compatible tool. Jobs interrupted by an app restart are marked in history.
- Editable captions. Correct text and timing, search captions, import/export SRT or VTT, and choose selectable MP4 subtitles or styled captions burned into video.
- Workflows and watch folders. Save a sequence of supported operations for multiple files. Explicitly enable a watch folder while the app is open to process stable files, skip outputs and already processed files, and review or retry results.
- Voice Cleanup. Adjust local noise reduction, compare a short before/after preview, and optionally normalize loudness. RNNoise mode requires a separately supplied model.
- Thumbnail Generator. Export an individual JPEG/PNG video frame or a configurable contact sheet.
- Media Tracks. Inspect and select audio/subtitle tracks, remove audio, or replace it with controls for duration differences.
- Export reliability. Fixed split filename collisions, mixed-audio merges, progress reporting, batch failures and cancellation, special characters in file paths and watermarks, and incompatible container/codec combinations.
- Failed or cancelled processing preserves existing files. Empty or incomplete results are not published as finished exports, and missing files receive clearer diagnostics.
