ARW to MP4 Converter

How to Convert ARW to MP4 Online

1. Upload Your ARW Files: Drag and drop or click "Add Files" to select Sony Alpha RAW photos. Batch is supported — drop a full burst, bracket, or timelapse sequence at once.
2. Pick Merge Strategy and Quality Preset: Choose "Merge images" to combine the whole sequence into a single MP4, or "Video per image" to render each ARW as its own clip. Under File Compression, leave Quality Preset on "Very High (Recommended)" for archival output, or switch to Constant Quality (CRF) for finer control — lower CRF values mean better quality at larger file size.
3. Set Duration, Background Color, and Resolution (Optional): Pick how long each frame holds via the Duration dropdown — anywhere from 1/60 second (for smooth 60-fps timelapse) up to 10 seconds (slideshow pacing). Choose a Background Color for letterbox bars when source aspect ratio differs from output. Under Video Resolution, keep original, pick a Preset Resolution (2160p, 1440p, 1080p, 720p, 480p, 360p, 240p, 144p), set a Fixed Resolution (1920x1080, 3840x2160, 1080x1920 vertical, etc.), or enter custom Width x Height while preserving aspect ratio.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no compression on upload to a third-party server.

Why Convert ARW to MP4?

ARW is Sony's Alpha RAW container, based on the TIFF specification, used by Alpha mirrorless bodies (A1, A7, A7R, A7S, A9 series), the ZV-E and FX cinema line, RX compacts, and legacy DSLR-A bodies. RAW files store 14-bit sensor data with full exposure latitude — but they're also large (a single uncompressed ARW from a 61MP A7R V runs roughly 120 MB; compressed ARW from a 50MP A1 runs roughly 50 MB) and require dedicated software to view. MP4 with H.264 video plays everywhere, on every browser since 2010 and every smartphone since the iPhone 4.

• Timelapse rendering — A 600-frame golden-hour sequence becomes a 25-second 1080p clip at 24 fps without leaving the browser. Tools like LRTimelapse and Adobe Premiere can do this but require a desktop install and a Lightroom subscription; this runs in any modern browser.
• Portfolio reels — Stitch 20 selected portraits at 3 seconds each into a 60-second showreel for Instagram, Behance, or a Squarespace gallery embed.
• Client proofing — Render a quick low-res MP4 from a wedding or event shoot so clients can scrub through 200+ images on their phone instead of downloading a 10 GB ARW dump.
• Social posts that need video — Instagram Reels, TikTok, and YouTube Shorts only accept video uploads; converting a still RAW sequence to MP4 unlocks those formats.
• Web embedding — A 5 MB MP4 loads on any device and supports autoplay/loop attributes, unlike a slideshow built from full-resolution stills.
• Archive-friendly delivery — Keep the ARW originals for re-editing; send clients the MP4 for review. The video bakes in your edits (white balance, exposure, contrast), so finalize those in Lightroom Classic, Capture One, or Imaging Edge before export.

Sony Cameras That Produce ARW

Frequently Asked Questions

How many ARW frames do I need for a 30-second timelapse?

Multiply target duration by frame rate. A 30-second clip at 24 fps needs 720 frames; at 30 fps it needs 900. If you shot at one frame every 5 seconds, 720 frames covers 60 minutes of real time. Set Duration to 1/24 second per image in the converter to get exactly 24 fps from 720 ARW frames.

Will my color edits, lens correction, and exposure adjustments transfer?

No. ARW carries 14-bit sensor data plus camera metadata, but converting straight from ARW bakes in the converter's default rendering. For graded output, develop your ARWs in Lightroom, Capture One, or Sony Imaging Edge first, export to JPEG or TIFF at full resolution, then convert that sequence to MP4 (use JPG to MP4 if you've already developed to JPEG). The same applies to noise reduction and lens profile corrections — finalize before video render.

Should I keep the original 9504x6336 resolution or scale down?

For YouTube 4K delivery, 3840x2160 is the practical ceiling — anything larger gets downsampled by YouTube's encoder. For Reels and TikTok, output at 1080x1920 vertical. "Keep original" preserves up to 9504x6336 (A7R V) or 8640x5760 (A1), which produces files of 50–200 MB per minute and won't upload cleanly to most social platforms. 1080p (1920x1080) covers 95% of viewing scenarios.

Why does my ARW sequence flicker after conversion?

Flicker comes from inconsistent exposure or white balance between source frames — common when shooting timelapse in aperture priority or auto white balance. The fix is upstream: lock manual exposure, manual white balance, and manual focus before shooting, or run the ARWs through LRTimelapse to de-flicker before export. The MP4 converter renders frames as-supplied.

Can I add audio or music to the MP4?

Not in this tool — the output is video-only. After downloading the MP4, add audio in DaVinci Resolve (free), CapCut, iMovie, or any NLE. You can also keep the silent MP4 and add a music track when uploading to TikTok/Reels via their built-in audio library.

Does converting ARW to MP4 work on Sony's lossless and lossy compressed RAW formats?

Yes for both — the converter accepts all ARW variants Sony has shipped (ARW 2.x through ARW 4.0 lossless compressed, introduced 2021). cRAW and uncompressed ARW from A1, A7R V, A9 III, FX3, ZV-E1, and older bodies all process the same way.

What's the difference between "Merge images" and "Video per image"?

Merge images produces one MP4 containing every uploaded ARW as a sequential frame — the slideshow/timelapse output 95% of users want. Video per image renders each ARW into its own short MP4 with the chosen Duration — useful when you want to drop individual clips into a video editor and assemble them with transitions yourself.

Should I use H.264 or H.265 for output?

H.264 (the default in this tool) plays on essentially every browser and device made since 2010, including older smart TVs and the Roku 1. H.265/HEVC produces files roughly 40-50% smaller at the same visual quality but requires hardware decode — supported on Safari 11+, Chrome 107+, Edge 107+, Firefox 120+, iOS 11+, and Android 5+. If your audience is mostly mobile and modern desktops, ARW to HEVC saves bandwidth; for maximum compatibility, stay on MP4 H.264. For animated GIF output instead of video, see ARW to GIF.

Can I trim or reorder frames inside the converter?

Frames render in the upload order, so reorder by renaming with a leading zero-padded index (frame_0001.ARW, frame_0002.ARW...) before upload. The converter doesn't expose mid-render trim controls — to drop frames, remove them from the upload batch, or trim the finished MP4 in a downstream tool. For a single-image output, ARW to JPG or merge ARW to PDF may fit better.
