Kdenlive

Opening a .kdenlive file converts the active timeline into a new Shrimply project. This is a one-way conversion. Media stays at its original path, and proxy files are ignored. The source files have to remain where the project points.

Only the Supported and Approximate rows below are converted. Anything else is left out, even when Shrimply has a similar feature.

Status meanings

Status	Meaning
Supported	The handled fields come across.
Approximate	Comes across, with some detail simplified or dropped.
Not imported	Left out, or kept only as a media path Shrimply may not play.
Import stops	Import fails and writes nothing.

Project and timeline

Kdenlive feature	Status	What you get
Frame rate and canvas size	Supported	Taken from the project profile.
Pixel aspect, scan mode, color metadata, profile name, and audio settings	Not imported	Shrimply keeps its own defaults.
Project name	Approximate	The .kdenlive filename. Kdenlive’s project title is ignored.
Video and audio track order	Supported	Black tracks and timeline-preview tracks are dropped.
Track enabled state	Supported	Kdenlive’s hide setting (audio, video, or both) becomes the track’s on/off state.
Track names, locks, height, collapse, targeting, and track effects	Not imported	Dropped.
Gaps, clip positions, in/out trims, and source durations	Supported	Positions, gaps, and trims follow the project frame rate.
Both lanes of one Kdenlive track	Approximate	Each non-empty lane becomes its own track. Mixes between lanes are dropped.
Nested sequences	Approximate	Sequences used on the timeline become folded sequences. Unused bin sequences, and captions inside nested sequences, are left out.
Mixes, crossfades, wipes, and compositions	Not imported	Dropped.
Timeline markers and clip markers	Approximate	Become comments with their text. Range length is kept. Point markers become one-frame comments. Clip markers follow that copy’s trims and speed, including reverse. Markers inside a nested sequence show on the active timeline. Overlapping comments go on separate tracks. A clip that is both audio and video produces one comment. Category colors use Shrimply’s palette. The comments do not move if you later edit the source clip.
Clip groups, zones, notes, bin folders, thumbnails, and unused bin clips	Not imported	Dropped.
Preview guides and editor UI state	Not imported	Dropped.

Media and generators

Kdenlive source	Status	What you get
Video and audio files	Supported	Imported with the selected video or audio stream. Playback still depends on Shrimply’s media support.
JPEG, PNG, WebP, BMP, TIFF, GIF, SVG, and PDF	Supported	Imported as images. A PDF uses its first page.
Krita and PSD layered images	Supported	Layers are imported. Scaling uses nearest-neighbor.
Constant speed, reverse playback, and pitch preservation	Supported	Speed, reverse, and pitch lock come across, including reversed trims.
Variable speed (time remap)	Not imported	Speed ramps are left out.
Source dimensions, stream selection, and media rotation	Supported	Imported when the file records them.
Proxies	Approximate	The original file is used. The proxy is ignored.
Solid color	Supported	Imported as a solid background, including transparency.
Color bars	Approximate	Imported as Shrimply’s static Test Pattern. Kdenlive’s bar styles do not match, so the chosen style is dropped.
White noise	Approximate	Imported as Shrimply white-noise video and audio. The noise pattern and stereo image are not reproduced, and a trimmed start can be off.
Counter, including its beep	Approximate	Direction, text style, drop-frame counting, trims, and the gray background become animated text. Beep tones become separate one-frame 1 kHz sine clips. The typeface can differ. The clock background’s rings, crosshair, and sweep are left out.
Other generators and playlists	Not imported	Left as media paths Shrimply may not play.
Title clips and title templates	Not imported	Left out.
Image sequences and slideshows	Not imported	Slideshow timing is left out.
Missing-media placeholders	Not imported	Stay missing. Shrimply keeps the saved path.

Color bars, white noise, and counter clips are usually stored in separate .mlt files next to the project. Those files have to be readable during import. After conversion, the Shrimply item no longer needs the generator file.

Video effects

Only enabled effects on a timeline clip are imported. Effects on the bin clip, the track, or the sequence are skipped.

Kdenlive effect	Status	What you get
Transform	Approximate	Position, scale, rotation, anchor, opacity, and their keyframes come across, including non-uniform scale. Stacked transforms are combined. Shear, and clipping in the middle of a stack, can be off.
Normal and Screen blend modes	Supported	Other blend modes become Normal.
Crop	Approximate	An animated rectangular crop comes across. Rounded, circular, or colored padding becomes a plain rectangle. A crop after rotation can follow the unrotated source.
Gaussian blur	Approximate	Blurring only color, or only alpha, is kept. Any other channel choice blurs the whole image.
Chroma key	Approximate	Key color, variance, and similarity come across, including animation on variance and similarity. An animated key color becomes one color. Other key settings use Shrimply’s defaults.
Saturation	Supported	Imported as color correction, including animation.
Hue shift	Supported	Imported as color correction, including animation.
Lift / gamma / gain	Approximate	The red channel becomes brightness, gamma, and value. Differences between channels are dropped.
Fade from or to black	Supported	Imported as a clip fade in or fade out.
Selective color correction	Not imported	Dropped.
Every other video effect	Not imported	Dropped.

Effect masks

Rectangle and ellipse Alpha Shapes masks are Approximate. They can cover Crop, Gaussian Blur, Chroma Key, Saturation, Hue Shift, and Lift / Gamma / Gain. A group of those effects shares one Shrimply mask.

Other mask shapes, other mask modes, nested groups, and groups that contain any other effect are left out.

Audio effects

Kdenlive audio feature	Status	What you get
Clip fade in and fade out	Supported	Imported as audio fades.
Constant gain	Supported	Imported as a decibel Gain modifier.
Animated volume	Supported	Level keyframes become a Gain modifier.
Every other audio effect	Not imported	Dropped.
Track audio effects and mixing	Not imported	Left out. Only effects on the clip are imported.

Captions

Kdenlive caption feature	Status	What you get
Subtitles on the active sequence (ASS)	Approximate	Timing, text, line breaks, and hard spaces come across.
Hidden subtitles	Supported	A hidden subtitle track stays disabled.
Fonts, outlines, position, and other styling	Approximate	Replaced with one centered caption at the bottom.
Captions in nested sequences, and other subtitle formats	Not imported	Left out.

When import stops

Import writes nothing if the project structure is invalid, or if a supported effect or an attached file it needs is malformed. That includes a broken project file, a missing frame rate or timeline, bad values in a supported effect, and an unreadable PDF, layered image, subtitle file, or generator file.

A missing media file is not an error during import. It shows up when Shrimply tries to play that clip.
