Concat Files

Concat 0.2.3

A self-contained build for every platform Concat ships on.

What changed

• Version 0.2.3
• A waveform's bars are one pitch on screen at every zoom
• Create ARCHITECTURE-TODO.md
• A Kbd primitive, and the timeline shortcuts shown as keycaps
• The Remote address is two fields around a colon, the port a number
• Thinner, denser candles on the lanes; the bin's cards keep theirs
• Waveforms at unity, scaled by the volume where they are drawn, a bar every four pixels
• Delete TODO.MD
• One way to split, at the playhead; the razor tool is gone
• Waveforms stand on the floor, and the part over -6 dBFS goes amber
• Text preset cards are square, with one sample size for every look
• Lane switches on the left, the cross on the right, and a wider column
• Drop FFmpeg's log lines below the level before formatting them
• FFmpeg's log goes through the log facade, not standard error
• Words typed into Content are never lost on the way out
• Air above and below the library's page chips
• Taller lanes, so frames and waveforms have room
• A recent project's poster is never a black frame
• The active timeline tab loses its lime top bar
• The sound band under a video is the video's blue, not a sound clip's green
• The Text tab remade, with a colour picker worth the name
• A title is a box, sized by width and height, and never stretched
• The magnetic timeline, a switch that closes every gap
• Ripple delete, ⇧⌫ closes the gap a deletion leaves
• Open on a software adapter, and say why when the window cannot start
• One face, Hanken Grotesk, for the window and the titles
• Waveforms at the resolution of the zoom, and a sound band under every video
• Sound is green
• The tests say whether a drop ripples
• The launch screen takes three shapes by its width
• A table of how fast the parts that matter are, against budgets
• One title bar on Linux, the strip's own
• A constant-rate stream is indexed at its base rate, and the end is remembered
• One frame plan describes the frame, and both compositors draw it alike
• The locale table counts the Persian file, and every locale covers the inventory
• One scheduler decodes for the screen, and a large file gets a proxy
• The frame cache keys on the source frame, and a scheduler decodes ahead
• Bump BUILT_IN locale array length for fa
• Add Persian (fa) locale
• Captions land above the video, not under it
• Ripple existing clips right when a drop would overlap them
• Has_non_finite catches transition_in and text in UpdateClip
• Create timeline.rs
• A Settings switch for decoding on the hardware
• I18n: the token hint reaches every locale
• A pass carries its package and the values it was written from
• Video decodes on the platform's hardware behind a toggle
• The Remote page shows the token the server made up
• Every connection presents a token, minted when none is set
• Home and End stay in the text field being typed into
• A title's words reach the monitor as they are typed
• A single JPEG is a still, not a one-frame video
• Pan tool for the timeline
• A null crop in a patch takes the crop off
• Decode on every core
• Settings toggle for flip and reverse shortcuts
• Remove dead editor-shortcut callback from lib.rs
• Add flip/reverse keyboard shortcuts and Settings context menu toggle
• A key stays on its instant of the picture through split, trim, freeze and merge
• Cuts keep a reverse, numbers must be finite, the reader clamps like a command
• The Remote page and the Hologram effect reach every locale
• Watch only package files that exist
• A branching effect chain opens on the CPU renderer
• The mix ends by sample count, and cuts each clip at its in-point
• The mux hands the interleaver whichever packet is due next
• A Hologram effect, from holo-stage
• Update issue templates
• A freeze leaves reversed and curved pieces the way a split does
• Compare mux PTS in a common unit, not raw ticks
• Mux video and audio by timestamp, not one packet each
• Stamp mix input PTS from sample count, ignore source timestamps
• Keep in-point trim in graph, move out-point trim to Rust
• Trim audio in Rust by sample count, not by PTS in the graph
• Heal source timestamp discontinuities before the per-clip trim
• Treat filtergraph EOF as graceful input end in audio mix
• Clamp with crossed bounds is an error, not a panic
• A Remote page in Settings serves the API while the window is open
• The Concat API on a socket, JSON-RPC lines and gRPC
• Revise security policy for supported versions
• Ids, error codes, exports as jobs, and frames inline
• A title being dragged is painted in memory, not to disk
• A title's side grips set where its words wrap
• The select's list scrolls, tips wrap, and two tray tips say less
• A download source setting, hf-mirror, and downloads that resume
• A document picker on Android, and a compact dock for narrow windows
• The window keeps out of the system's bars

Download

Every bundle runs with nothing else installed.

• macOS: open the .dmg and drag Concat to Applications. If macOS says the app cannot be checked, right-click it and choose Open once.
• Windows: run the -setup.exe; it puts Concat in the Start menu and can take it out again. The .msi is the same program for an administrator to deploy, machine-wide.
• Linux: install the .deb or the .rpm with your package manager, or chmod +x the .AppImage and run it; no install needed.
• Android: open the .apk on the phone and allow the install from this source; Android 8.0 or newer, 64-bit.
• iOS / iPadOS: sideload the .ipa with AltStore, Sideloadly or Xcode's Devices window, which sign it with your Apple ID; iOS 15 or newer.

SHA256SUMS lists each file's checksum.
