iTunes vs IINA

There is a feature included in iTunes called Smart Playlists that allows the user to create playlists based on criteria such as BPM, Genre, Artist, Album, Plays, Rating, etc.

There is a feature called Genius included in iTunes that allows the user to select a song and create a playlist based on that song. It will analyze the music library and choose songs similar in tone to the one chosen.

Synchronization of playback information, podcast subscriptions, and settings is possible in iTunes. It can also automatically download purchases made on other devices.

Streaming audio to all Airplay enabled devices within WiFi range is permitted by iTunes. It's also possible to select more than one device to play a song at the same time.

The user can set up iTunes in such a way that media (from CDs) can be automatically imported once a CD is inserted. This also comes with customizable import settings (bitrate, codec). Additionally, iTunes can automatically fetch track names from the Internet.

iTunes parental controls can be used to deny access to certain parts of iTunes such as podcasts, internet radio, store, or shared libraries, as well as restricting access to media that has a certain rating or warnings.

Track names and album artwork can be automatically obtained by iTunes.

The interface of iTunes presents a flat, clean design with playback controls at the top-left, search at the top-right, and a row of ways to categorize available media beneath that. It can also be minimized to take up much less space. The minimized interface is called the Mini Player and it can be set to display on top of all other windows. It's possible to show iTunes on top of all other windows when playing movies as well.

The iTunes store offers a huge catalog of videos, songs, and podcasts.

A music streaming service called Radio is available in iTunes. It creates stations based on chosen genres, songs, or artists and requires Apple ID for access.

The ability to add RSS feeds in iTunes keeps the user informed of the latest web content.

It's like mpv, just more user friendly GUI and more settings available via UI.

Extremely stable, even while still in the beta.

Supports lots of video codecs, like mp4, mkv, etc, and lots of audio codecs including opus.

It can black out other screens if you want, but out of the box it leaves your other displays alone.

Tip: if you're doing a lot of cropping and slicing of videos and you thought the new quick tools in Finder / Quicktime Player are a great improvement, try setting up IINA with slicing.lua and some keybindings for navigating your video + setting the slicing positions.

Make sure your ffmpeg command (in slicing.lua) is set to copy the original codecs and that it's using your GPU.
