Mizune 1.3.1

The controls in full view now get out of the way on their own.

On a computer

• With the panel put away, the controls no longer stay up for as long as the pointer rests at the edge of the video. They come up when it moves there, and go, along with the pointer, two seconds after it last moved there, even if it has moved back to the middle in the meantime.

Mizune 1.3.0

Continue watching at the top of the library, a volume control on a computer, and a welcome on the phone that sets up AnkiDroid.

On both

• The top of the library has Continue watching: the video you last stopped partway, with its show, episode and time left, and the frame where you left off. It plays from there, and going back from the player takes you to its folder. On a computer this replaces the bar from 1.2.0.
• A video opens behind a cover in the theme's colour and starts once its picture, subtitles and the first line's lookup are all in, so it no longer comes together piece by piece.
• Turning on Anki cards in the welcome now picks the deck and note type too, so the first card can be added straight away.
• The player's menus are laid out afresh. Audio and subtitle tracks are named by their language, with details such as "Stereo · AC3" beside them.

On your phone

• A new install starts with a welcome, like the computer's: a look, the peek language, your video folder and AnkiDroid. If AnkiDroid doesn't answer, it says how to turn on its API, and so does Settings › Anki.
• Themes are picked the way they are on a computer: a family, then Auto, Light or Dark. The theme you had carries over.
• The player's options are grouped like the computer's menus, and fit side by side when the phone is sideways.
• With the panel put away, the line over the video sits lower, and stays put as the controls come and go.
• The seek line looks like the computer's.
• A notice in the middle of the video keeps its words while it fades.

On a computer

• The play bar has a volume control. Point at the speaker to show the slider, click the speaker to mute, or scroll over it. Changes are heard at once, and the volume carries over to the next video.
• Adding a card the deck already has asks first, and Add it anyway adds it. Never warn me turns the question off; Settings › Anki › Warn about duplicates turns it back on.
• In the light themes, the played part of the seek line is the same colour as the player's other controls.
• On a Mac, the window buttons stay put while the window is resized, and the play bar's track cog hides while the panel, which has its own, is open.

Mizune 1.2.0

Look things up without the panel on your phone, pick up where you left off on a computer, and updates you can see coming.

On your phone

• With the panel put away, the line over the video works like the panel: tap a word to look it up, hold anywhere on the video to peek, and swipe sideways for the previous or next line.
• Double-tap the middle of the video to stop at the end of every line. Double-tapping the edges still jumps 5 seconds.
• The seek line can be dragged again when the phone is sideways.
• The panel's edge can be grabbed anywhere along it, and the video follows it smoothly.
• Lock landscape, under the player's cog, keeps the player sideways however you hold the phone.
• Library folders open much faster, especially big ones.
• A fresh look for the player's buttons, options and text.

On a computer

• The library offers to pick up where you left off: the last video you stopped partway, with its time left. Play it from there, or open its folder.
• Drag anywhere on the video to move the window.
• The window fits your screen the first time, and opens where you left it after that.
• On a Mac, the window buttons stay put going in and out of full screen.
• On Windows, videos open from folders and file names that aren't in English letters.
• Mizune's icon stands out on the light themes.

Updates

• A new version shows in Settings, and in the library's header unless you turn that off, with how far its download has got.
• Updates wait for a connection that isn't metered, like a phone's hotspot.
• Turn off Update automatically to choose when a new version downloads.

Mizune 1.1.1

Subtitles inside MP4 files now show.

Subtitles inside MP4 files

• Subtitles stored inside an MP4, M4V or MOV file now load, as they already did for MKV and WebM.
  Before, an MP4 with no subtitle file beside it played with none.
• A subtitle file beside the video still comes first for its language, and the video's own
  subtitles fill in the others.

Mizune 1.1.0

Peek in your own language, subtitles that used to go missing, and keys of your own.

Peek in your language

• The translation you peek at can be in any of 19 languages now, not only English, or switched off
  if you'd rather not be tempted. Choose it in Settings, or during setup on a computer.
• Mizune doesn't translate or download subtitles, so the language you choose needs subtitles of
  its own, in the video or in a file beside it.

Subtitles that went missing

• Subtitles inside a video now load even when there's a subtitle file beside it. Japanese from a
  file with English inside the video gives you both.
• Subtitle files saved in older formats now read as text instead of question marks: Arabic,
  Chinese, Korean, Russian, Japanese Shift_JIS and more.
• In Arabic and Hebrew lines, a click or tap lands on the letter you meant.

Your own keys (computer)

• Every player key can be changed under Settings › Keyboard. Save your layout to a file to keep or
  share it, and load one from a file.

And on a computer

• A dark app icon, under Settings › Appearance › App icon.
• The upscaling and stop-at-every-line buttons stand out in light themes, and the upscaling button
  now wears Mizune's face.

• Mizune-1.1.0-macos-arm64.dmg: Apple Silicon, macOS 12 or newer.

Mizune 1.0.0

Immersion Player is now Mizune, and this is 1.0.

Meet Mizune

• The app has been renamed to Mizune (水音).
• Used Immersion Player before? Mizune is a new app, so it can't update the old one. Install it from
  the files below, set it up, and then the old one can go.

A short tour the first time you play

• The first video you open begins with four little cards, each with an animation: looking up a word,
  moving line by line, peeking at the translation, and the rest of the controls. Keys on a computer,
  gestures on Android.
• Seen it and want it again? It's under Settings › Keyboard on a computer, and Settings › Appearance
  on Android.

And

• Fit the whole picture or fill the area from the player's cog, as well as with Z.
• On a Mac, the video and the panel are rounded cards from the start.

Install

• Mizune-1.0.0-macos-arm64.dmg: Apple Silicon, macOS 12 or newer.
