Aevum 1.2.0

The clip update. Also the biggest one so far.

New

  • Preview card — paste a link and see the title, channel, duration and thumbnail before you download anything.
  • Honest quality buttons — resolutions the video doesn't offer are dimmed, and if your pick isn't available the app falls back to Best instead of failing. Tip: hold the pointer over a quality button for a second and a small tooltip shows the approximate file size.
  • Clip downloads — enter a start and end time to grab just that section. Cuts are frame-exact by default and run at full download speed. A small "Lossless cut" option keeps the original stream bytes instead (the cut then snaps to the nearest keyframe, so the clip can start a few seconds early). Works in audio mode too, always exact there.
  • Thumbnail button — saves the cover image as jpg; the video and its cover land in their own subfolder.
  • H.264 preset — an mp4 that is guaranteed H.264, for editors and older devices that refuse AV1. WebM preset — VP9, best quality per megabyte.
  • Subtitles that actually embed — the uploader's own subtitles go inside the file now (correct subtitle format per container; auto captions are not used). If none could be embedded, the app says so instead of staying silent.
  • Live download speed — MB/s next to the progress bar, for every download type including clips.
  • Guide panel — the ⓘ button explains every option in one line each, in all 8 languages.
  • More themes — Teal, Amber, Crimson and Mono join Green/Blue/Purple, plus a second color-cycling mode (Calm) that drifts through the palette slowly.
  • Single instance — launching Aevum while it's already running now just opens the running app instead of stacking a second one in the tray.

Fixed

  • Long clips used to freeze at 0% or grind for hours. Two separate causes: the bundled ffmpeg 8.1.x hangs forever on YouTube range requests (documented upstream in yt-dlp#16546 — Aevum now ships ffmpeg 8.0 and the CI refuses to bundle 8.1.x), and exact cuts re-encoded with encoder defaults (they now use a fast encoder that keeps up with the download, so an exact cut costs no extra time).
  • Audio clips no longer come back ~10 seconds longer than requested.
  • A new link clears the previous clip range, so a stale range can't silently cut the wrong section.
  • Memory no longer creeps up over long tray sessions.

Under the hood

  • Bundled yt-dlp updated to 2026.07.04.
