DCR to FLV Converter

How to Convert DCR to FLV Online

1. Upload Your DCR Files: Drag and drop or click "+ Add Files" to load Kodak DCR RAW photos. Batch upload is supported — drop an entire shoot from a DCS Pro 14n or DCS 760 in one pass and the converter queues every frame.
2. Pick a Merge Strategy: Choose Merge images to splice every DCR into a single FLV slideshow, or Video per image to emit one FLV per photo. Set Duration to control how long each frame holds (default 5 seconds; choose anywhere from 1/60 second for animation-style flipbooks up to 10 seconds for portrait viewing).
3. Tune Output (Optional): Open Quality Preset and pick Constant Quality for visually consistent frames or Constraint Quality for a tighter average bitrate. Use the Preset dropdown (Very High, High, Medium, Low) to bias size vs. detail. Set Video resolution with Keep original, a Preset Resolution (2160p, 1440p, 1080p, 720p, 480p, 360p, 240p, 144p) or a Fixed Resolution with custom width/height. Use Background Color (default Black, 24 named colours) to control the letterbox fill when the DCR aspect ratio doesn't match the output frame.
4. Convert and Download: Click Convert and grab the FLV directly or as a ZIP for batch runs. Processing happens in your browser session — no sign-up, no watermark, no email gate.

Why Convert DCR to FLV?

Kodak's DCR is a TIFF-based RAW container used by the DCS Pro 14n, DCS Pro SLR/n, DCS Pro SLR/c, DCS 760, DCS 720x, and the DCS Pro Back medium-format digital backs. Kodak announced the DCS Pro 14n at photokina in September 2002, shipped it from May 2003, and discontinued the SLR/n and SLR/c lines in May 2005 — closing Kodak's professional DSLR business and freezing DCR as a legacy archive format. Twenty years on, photographers still have hard drives of DCR files from those bodies, and turning them into a video container is the easiest way to share a contact sheet without sending raw 14-bit sensor data.

FLV (Flash Video, container .flv) was Macromedia/Adobe's RTMP delivery format from around 2002 until Adobe ended Flash Player support on December 31, 2020. The container itself isn't dead — VLC, MPV, ffmpeg, and Adobe Animate still read and write it — but you should only ask for FLV if a downstream system specifically requires it. Common reasons:

• Legacy CMS and LMS imports — older WordPress, Joomla, Drupal, Moodle, and SCORM 1.2 packages ship with FLV-only video widgets that won't accept MP4 without re-templating; an FLV slideshow drops straight into those slots.
• Wowza, nginx-rtmp, and OBS RTMP testing — many local streaming stacks still accept FLV file ingest for offline regression tests of RTMP and HLS-from-RTMP pipelines, and a 30-second DCR slideshow is a useful synthetic feed.
• Legacy banner ads, kiosks, and museum installations — interactive kiosks built on Director/Shockwave or Flash Projector hardware that survived the 2019 Shockwave EOL still loop FLV assets locally.
• Adobe Animate publishing — Animate (formerly Flash Professional) still imports and exports FLV for HTML5 Canvas projects that fall back to legacy renderers.
• Archiving a photo set as a single playable file — sending 50 raw DCR files to a non-photographer is hopeless; a single ~5 MB FLV slideshow plays in VLC on any modern OS.

For new work, convert to DCR to MP4 or DCR to WebM instead — MP4 (H.264) plays everywhere FLV does, plus modern browsers, phones, and TVs that haven't shipped Flash since 2017. If you just need still images, DCR to JPG, DCR to PNG, and DCR to TIFF preserve the photo workflow.

Two Different "DCR" Formats — Make Sure You Have the Right One

This converter handles Kodak DCR RAW image files — the camera-sensor format. The same .dcr extension is also used by Adobe (Macromedia) Director Shockwave for interactive web media, and the two are unrelated.

Quick check: if the file came off a camera card and is larger than 5 MB, it's a Kodak DCR and this converter is the right tool. If the file came off a 2000s-era website and is under 1 MB, it's a Shockwave bundle and no online converter can play it — you'd need the original .dir source and Adobe Animate to migrate it to HTML5.

FLV vs Modern Video Containers

Frequently Asked Questions

Which Kodak cameras actually produce DCR files?

The DCR extension is written by the Kodak DCS Pro 14n (2003), DCS Pro SLR/n and SLR/c (2004), DCS 760, DCS 720x, DCS 660, DCS Pro Back, Pro Back Plus, and the Pro Back 645 M/C/H medium-format backs. Kodak introduced the format in the late 1990s as part of the DCS line and stopped producing professional DSLRs in May 2005. Newer cameras from Nikon, Canon, Sony, Fuji, etc. use their own RAW extensions (NEF, CR2/CR3, ARW, RAF) rather than DCR.

Is FLV still a sensible output format in 2026?

Only if a downstream system specifically requires it. Adobe Flash Player reached end of life on December 31, 2020, every modern browser has refused to load it since, and no phone has ever played FLV natively. Pick FLV when an older CMS, LMS (SCORM 1.2), RTMP ingest test, or museum kiosk needs that exact container. For anything else, convert DCR to MP4 — same H.264 video codec is allowed inside both containers, but MP4 plays everywhere FLV does plus on every modern device.

Can I merge a whole DCR shoot into one FLV slideshow?

Yes. Upload all the DCR files together, set Merge strategy to Merge images, and set Duration to the seconds-per-frame you want (5 seconds is a comfortable default for portrait viewing; 1 second produces a contact-sheet flick-through). The encoder concatenates files in upload order — drag them into the list to reorder before clicking Convert.

Will the RAW editing flexibility carry over to the FLV?

No. DCR captures 12–14 bits per channel of sensor data with adjustable white balance, exposure, and demosaic parameters. FLV stores 8-bit-per-channel YUV video frames after a fixed demosaic pass, so highlight-recovery, white-balance shifts, and tone-curve edits all need to happen in Lightroom, Capture One, or RawTherapee before you convert. Treat DCR→FLV like printing — once it's in the video container the RAW latitude is gone.

What's the largest DCR resolution this tool will accept, and will FLV hold it?

The DCS Pro 14n shoots 4536×3024 (13.89 megapixels), and the medium-format Pro Back lines go up to about 4080×4080. FLV technically supports any resolution your encoder will write, but most legacy FLV players choke above 1920×1080 — and a 4K FLV plays in essentially nothing. Use the Video resolution dropdown to pick 1080p or 720p unless you have a confirmed downstream that wants original resolution.

Why is my FLV so much larger (or smaller) than I expected?

Three knobs drive size: frame count (more DCR inputs × longer per-frame duration = more frames), resolution (1080p is roughly 4× the bitrate of 540p for the same perceived quality), and Quality Preset. Constant Quality holds visual fidelity per frame and lets size float; Constraint Quality caps the average bitrate and lets quality float. If you need an exact MB target, the easier path is to switch to a DCR to MP4 workflow where bitrate and CRF controls are more direct.

My .dcr file is only 200 KB — is something wrong?

Yes — that's almost certainly an Adobe/Macromedia Director Shockwave file, not a Kodak RAW. See the "Two Different DCR Formats" table above. Shockwave bundles can't be opened by image software because they aren't images; they're interactive multimedia programs that needed the now-defunct Shockwave Player plugin (Adobe ended support April 9, 2019). The only way to revive them is to dig up the original .dir source in Adobe Director and rebuild for HTML5.

Does the slideshow include audio, or can I add a music track?

This converter generates silent video — FLV inputs from images don't carry an audio track by default. If you need a soundtrack, encode silent FLV first, then mux audio in Adobe Animate, ffmpeg (ffmpeg -i slideshow.flv -i music.mp3 -c:v copy -c:a libmp3lame out.flv), or any video editor that still imports FLV.

Are my DCR files uploaded anywhere?

Processing happens in your browser session and files are deleted after the session ends. No account, no watermark, no email capture, and no Pro tier gating advanced options like resolution or quality preset.
