Important

Recommended: the launcher. It always installs the newest FPV DVR Cleaner: pick your system, and it downloads the latest release, checks it, deletes the old version and starts the app. Download it once; it updates the app from then on.
⬇ Windows · macOS Apple Silicon · macOS Intel · Linux

New in 0.8.0

In your language

FPV DVR Cleaner now speaks 15 languages: English, Deutsch, Français, Español, Italiano, Português (Brasil), Nederlands, Polski, Čeština, Русский, Українська, Türkçe, 日本語, 简体中文 and 한국어.
It follows the language of your system; when yours is not among them, it starts in English. The menu at the bottom of the step rail switches the language at any time: the app restarts in the new language and keeps the clips of your queue.
Every page, button, hint, tooltip and preset name is translated, and so are the error messages of the video engine. Chinese, Japanese and Korean text is drawn with your system's fonts for those scripts, and every page was checked in every language so that nothing is cut off or overlaps.

Tidier pages

Long labels on the Repair page wrap onto a second line instead of being cut off; small grey hints that do not fit end in "…".
On the releases page only the newest release keeps its notes open; older releases fold their "New in …" and downloads away. The README shows the pictures first, the technical details fold out below.

Earlier versions: see the changelog.

FPV DVR Cleaner v0.7.2

github-actions released this 26 Oct 05:36

v0.7.2

950944e

New in 0.7.2

Important fix: exports of whole recordings

In 0.7.1, exporting a recording without trimming it could stop with "Export failed: [Errno 32] Broken pipe" when its sound ends a moment before its picture, which is common for DVR files. Older versions finished such exports but cut the video to the length of the sound. Now the sound is filled with silence to the full length, and every frame is kept.
If the encoder ever stops early, the message now says why instead of "Broken pipe".
Every release is now checked by running the packaged app's engine on recordings with shorter, longer and no sound, with OSD removal and hand corrections, every file format, trims, preview, the mask editor and Share; lengths, sizes and sound are compared before anything is published.

Share is a plain export now

Share in the result view brings the cleaned clip into the right format, nothing more: 16:9 for YouTube (1920×1080, or 1280×720 for SD recordings; the picture centred on black) or 9:16 for Shorts, Reels and TikTok (1080×1920; the picture fills the screen and pans smoothly along with the action).
The card asks only for the format and the sound (on for 16:9, off for 9:16 unless you change it) and then Make video. The whole clip as you trimmed it, H.264 MP4 at up to 60 fps, saved next to the cleaned file as …-youtube.mp4 or …-short.mp4.
The original picture, side by side, wipe and flip layouts, labels, slow motion on repairs, "best N seconds" and the watermark are gone.

Earlier versions: see the changelog.

FPV DVR Cleaner v0.7.1

github-actions released this 26 Oct 03:40

v0.7.1

a72a795

New in 0.7.1

Share-ready before/after videos

After an export, press Share in the result view: one click on Make video turns the clip into a before/after video to post. The original and the cleaned clip are paired frame by frame, removed parts of the trim included.
16:9 for YouTube (1920×1080): side by side with ORIGINAL and CLEANED labels, a wipe with an orange split line that sweeps across, or a flip that switches between the two every two seconds.
9:16 for Shorts, Reels and TikTok (1080×1920): original above cleaned, or one full-screen cleaned picture under a moving wipe that follows the action.
Slow motion on the biggest repairs: frames where the repair changed the most, such as an HDZero breakup or a rainbow tear, are slowed to ×0.25 and frozen for a second, with a small tag.
Best 15, 30 or 60 seconds, chosen around the strongest repairs, or the whole clip. Sound is kept for 16:9 and left out for 9:16, where music is usually added on the platform; both can be changed.
A small Cleaned with FPV DVR Cleaner in the corner, which you can switch off. H.264 MP4 at 30 or 60 fps, saved next to the cleaned file as …-share.mp4 or …-short.mp4. Your choices are remembered.

Cleaner buttons

The zoom, transport and queue buttons use drawn icons, centred exactly; disabled queue arrows fade instead of changing colour.

Repair in two simple questions

The Repair page asks Signal (Analog or HDZero, preselected from the recording when it is clear) and How bad is it? (Light, Normal, Strong), with one plain line about what that does. Best quality switches on 1080p upscaling and the Best speed in one go.
OSD: Keep or Remove. With Remove, Fix by hand… opens a mask editor over the page: the frame large with the found OSD in orange. Paint or box in what the search missed (small icons, REC) and keep what it took by mistake; undo, redo and Reset to automatic. The corrections are kept per recording and used in the preview and the export.
My presets is a short list of your own settings with Rename, Update with current settings and Delete; presets from earlier versions are in it.
Everything else (output size, speed, each repair as a slider, the trained model) is under Advanced, with a Show button per repair that renders the frame without and with only that effect.
The big before/after frame updates on its own shortly after a change. The page fits the window without scrolling, down to 1080×700.
One slim slider style in the whole app.

Export by purpose

Choose what the video is for: Share & play anywhere (MP4 H.264), Smallest file (MP4 H.265), For video editing (MOV ProRes 422) or For the web (WebM). Quality, size limit, caption, file name, joining and MKV are under More options.
Without a chosen folder the files go to a Cleaned folder next to the first clip. Progress, remaining time and Cancel sit right under the big Export button.

Earlier versions: see the changelog.

FPV DVR Cleaner v0.6.0

github-actions released this 26 Oct 00:51

v0.6.0

3614b28

New in 0.6.0

Pick the file format

The Export page has a file format choice: MP4 · H.264 (plays everywhere, as before), MP4 · H.265 (smallest files), MOV · ProRes 422 (for video editors), MKV · H.264 (robust container) and WebM · VP9 + Opus (for the web). Each option says what it is good for, and your choice is remembered.
File names, numbered copies, joined clips and Auto refine follow the chosen format. ProRes ignores the quality and size settings, so they are greyed out for it.
WebM files can be imported, so a WebM export can be checked or refined again.

A finished look, if you want one

New Look card on the Repair page: colour grade, glow, vignette, film grain and lens fringe, each with a slider, or one of the presets Clean, Cinematic, Punchy and Retro FPV.
It is off by default and then changes nothing. When it is on, it is the last step after every repair, the frame preview shows it, and a second split compares the frame with and without it.
The grain follows the frame number, so the same cut exported twice gives the same file. Saved presets and your last settings include the look.

Sister project

Restoring VHS tapes or old 8 mm / 16 mm film is moving into its own app, Analog Repair.

New: the launcher

One small program that keeps FPV DVR Cleaner up to date on Windows, macOS and Linux. It detects your system and preselects it; you can still pick another one, for example to fetch the Mac version on a PC.
It downloads the newest release, checks its SHA-256 checksum, unpacks it next to itself (or into a folder you choose and that it remembers), deletes the old version and any leftover downloads, and starts the app.
Safe by design: the old version stays until the new one is complete; a running app, a full disk, a read-only folder or a broken connection stop the update with a clear message and nothing changed. Downloads resume after a dropped connection, and an install cut off by a crash or power loss is undone at the next start.

New in 0.5.0

Trim like in a video editor

The trim page is a real timeline: time ruler, filmstrip track, audio waveform, playhead with a grip. Split the recording at the playhead (S), click a part and press Delete: the parts before and after close up and a thin cut edge marks the join. Drag the fine [ ] edges to trim or to bring footage back, with snapping to cuts, bookmarks and the ruler.
Hover over the timeline to scrub, Ctrl+wheel to zoom around the pointer, wheel to scroll, bookmarks (B), undo and redo (Ctrl+Z / Ctrl+Y), jump between cut edges (Page Up / Page Down).
Playback decodes the real video now, so the preview runs smoothly instead of stepping through thumbnails. It skips the removed parts.
The export renders every kept part with the same settings and joins them without re-encoding, so the result is one file.
The editor grows with the window; F11 switches to full screen.

Watch the result, and know how good it is

After the export, original and cleaned clip play side by side or under a wipe, in sync, with the removed parts skipped.
Both clips come from one decoder, so they are frame-accurate to each other; nothing drifts at the wipe line.
A measurement of grain, colour noise and streaks shows what was gained, how much improvement is still possible without any loss, and what a second pass would cost in detail. Try other settings re-exports the original (lossless); Refine the cleaned file queues the result for a second pass and warns about the re-encoding loss first.
Both buttons pick the settings for the next round from the measurement: whatever artefact is left raises the control that fights it; a second pass also turns off what was already done (OSD removal, upscaling) and keeps the encode near lossless.
Auto refine does it in one click: settings from the measurement, the original exported again as a new file (nothing is overwritten, exports are numbered).
The split line of the comparison views is dragged in the picture itself, on the Repair page and in the finished-clip view.

Cleaner on one screen

Every page fits the window without scrolling at the default size: the trim editor is a dark, edge-to-edge workspace whose preview takes all spare height, the Repair page has three compact cards, and the export settings fold away once a result is shown so the video gets the room, also in full screen (F11).
Buttons, pills and inputs are smaller and lighter throughout.
While the engine works (reading clips, rendering a frame, the OSD search, export, training) the page dims and blurs behind one centred progress card, with a cancel button where it applies. The progress bar has a small quad flying at its tip.
Previews and the comparison views show the 4:3 picture only; the black side bars of 16:9 recordings are cropped away, and the wipe line runs inside the picture.

Repair around the cut

Half a second of footage before and after each kept part is decoded as context, so the first and last frames of a part are repaired from real neighbours instead of from one side only.

Quality of life

Presets for the repair settings, four built in; your last settings come back at the next start.
The cut of every recording is remembered, so a file you add again keeps its parts and bookmarks.
Export options: file name suffix, join all clips into one video, open the folder when done. The app comes back to the front when an export finishes.
Queue: move clips up and down, add a copy of a recording with its own cut.
The window starts centred on the screen; the square logo in the corner is gone.

OSD removal

The refill of each overlay follows the brightness gradient of its surroundings (sky, vignette) instead of using one flat offset, and the seam is feathered only outside the graphic, so no edge of the text shines through.
Where no neighbouring frame can fill a region, the spatial fill now carries the surrounding gradients into the hole (Navier-Stokes) instead of the fast-marching method, which left faint streaks that flickered on analog footage. In tests on analog footage the fill flickers about 25 % less.

New in 0.4.2

Export folder remembered

The destination folder of the export (and the recordings folder for model training) is saved when you choose it and is back the next time you start the app. The folder picker also opens there. Settings live in settings.json next to the trained models, under your user's application data folder.

Export fixed for good (issues #1 and #2)

0.4.1 already fixed the failing export (WinError 267 on Windows, Errno 2 … flugbild/assets on Linux). The engine now also finds its bundled font in every package layout and reports a clear message instead of a path error if a file is missing. Every build checks that the files are in the package and runs a real export, with and without a caption, through the frozen engine before a release is published.

Linux packaging (issue #2)

The Linux build is now also published as an AppImage: make it executable and start it, nothing to unpack.
The desktop app is one executable on Linux. The hundreds of .dll files are gone: they were .NET assemblies, not Windows libraries, but they had no business confusing anyone. Only two native .so libraries remain next to it.
Open output folder now works on Linux and macOS, not just on Windows.

New in 0.4.1

Important bug fixed: saving the export

Exports could fail with [WinError 267] The directory name is invalid ("Der Verzeichnisname ist ungültig"), no matter which destination folder was chosen. The video engine started FFmpeg in a folder that was missing from the packages. Exports work again, with or without a caption.

New in 0.4.0

CPU and GPU together

The heavy part of noise reduction and upscaling now runs on the graphics card: NVIDIA, AMD, Intel or Apple, through OpenCL. Optical flow, colour repair and OSD removal keep every CPU core busy at the same time.
Nothing to set up: the app checks the GPU with a short self-test and uses it when the result matches the CPU. Without a usable GPU everything runs on the CPU as before, with the same result.
In first tests on a laptop with an NVIDIA RTX 2000 Ada, exports with noise reduction and upscaling finished about 10–30 % sooner. How much you gain depends on your CPU and GPU.
Best now also runs its sharper (bicubic) frame alignment on the GPU.

Safer HDZero repair

Broken blocks are rebuilt only from frames that are free of confetti specks there, too.
White OSD text inside a partly broken frame is kept, so the stats screen no longer flickers on a weak link.

Tidied up

The old Qt prototype was removed from the source code. The app is unchanged.

New in 0.3.0

HDZero breakups rebuilt

When the digital link drops packets, parts of a frame or the whole frame turn into coloured confetti. These frames are now rebuilt from the clean frames before and after them, aligned with optical flow.
Only real breakups are touched: on two test flights, about one frame in 750. The OSD, text that just appeared and colourful scenery are left alone.
On by default for HDZero: choose the HDZero signal on the Repair page. Block repair sets how eagerly it repairs; 0 turns it off.
The README shows what is detected and how it is rebuilt.

Cleaner OSD removal

The stats screen after landing, or ARMED at the start, is now removed only while it is on screen. Before, it was painted out of the whole flight and left smeared patches.
Straight edges in corridors and window frames are no longer mistaken for warnings. Real warnings such as LOW BATTERY or CRASH FLIP are still removed.

Windows and Linux now ship an FFmpeg build with the H.264 encoder the export needs.

0.4.1 already fixed the failing export (WinError 267 on Windows, Errno 2 … flugbild/assets on Linux). The engine now also finds its bundled font in every package layout and reports a clear message instead of a path error if a file is missing. Every build checks that the files are in the package and runs a real export, with and without a caption, through the frozen engine before a release is published.

Linux packaging (issue #2)

The Linux build is now also published as an AppImage: make it executable and start it, nothing to unpack.
The desktop app is one executable on Linux. The hundreds of .dll files are gone: they were .NET assemblies, not Windows libraries, but they had no business confusing anyone. Only two native .so libraries remain next to it.
Open output folder now works on Linux and macOS, not just on Windows.

New in 0.4.1

Important bug fixed: saving the export

Exports could fail with [WinError 267] The directory name is invalid ("Der Verzeichnisname ist ungültig"), no matter which destination folder was chosen. The video engine started FFmpeg in a folder that was missing from the packages. Exports work again, with or without a caption.

New in 0.4.0

CPU and GPU together

The heavy part of noise reduction and upscaling now runs on the graphics card: NVIDIA, AMD, Intel or Apple, through OpenCL. Optical flow, colour repair and OSD removal keep every CPU core busy at the same time.
Nothing to set up: the app checks the GPU with a short self-test and uses it when the result matches the CPU. Without a usable GPU everything runs on the CPU as before, with the same result.
In first tests on a laptop with an NVIDIA RTX 2000 Ada, exports with noise reduction and upscaling finished about 10–30 % sooner. How much you gain depends on your CPU and GPU.
Best now also runs its sharper (bicubic) frame alignment on the GPU.

Safer HDZero repair

Broken blocks are rebuilt only from frames that are free of confetti specks there, too.
White OSD text inside a partly broken frame is kept, so the stats screen no longer flickers on a weak link.

Tidied up

The old Qt prototype was removed from the source code. The app is unchanged.

New in 0.3.0

HDZero breakups rebuilt

When the digital link drops packets, parts of a frame or the whole frame turn into coloured confetti. These frames are now rebuilt from the clean frames before and after them, aligned with optical flow.
Only real breakups are touched: on two test flights, about one frame in 750. The OSD, text that just appeared and colourful scenery are left alone.
On by default for HDZero: choose the HDZero signal on the Repair page. Block repair sets how eagerly it repairs; 0 turns it off.
The README shows what is detected and how it is rebuilt.

New in 0.2.0

Much faster

Frames are repaired on all CPU cores at once.
The black side bars of 4:3 goggle recordings are skipped: about a quarter less work, for analog and HDZero.
New Processing speed setting on the Repair page: Fast, Balanced (default) or Best.
One minute of 720p60 analog footage with every option on, upscaled to 1080p: 6.6 minutes with Balanced (55 minutes in 0.1.0), 4.8 minutes with Fast. Measured on a laptop; see the chart in the README.

Cleaner OSD removal

The stats screen after landing, or ARMED at the start, is now removed only while it is on screen. Before, it was painted out of the whole flight and left smeared patches.
Straight edges in corridors and window frames are no longer mistaken for warnings. Real warnings such as LOW BATTERY or CRASH FLIP are still removed.

Packages

Windows and Linux now ship an FFmpeg build with the H.264 encoder the export needs.

Download v0.5.0 and first start

Clean up analog and HDZero DVR recordings on your own computer: rainbow stripes, colour dropouts, HDZero breakups, noise and the OSD. Unpack and start; the app, the video engine and FFmpeg are included, so you don't need to install Python or FFmpeg.
