Have not been successful with this, best Ive been able to do was add an image to just the thumbnail view of the file but otherwise just a horrible pictureless checkerboard placeholder shows throughout the file during playback

Edit: [used Shotcut] discovered if import the cover jpeg in with the other file(s) and drag it to the playback window (it will be checkerboard pattern if no image) it embeds the album art thruough the entire output file.

    I might have figured it out. Using Shotcut

    add original audio/video track to timeline, > add new video track to timeline > add the image to the timeline > change timeline video track( image) properties to the same duration of the original audio/video track (I’ll see how it turns out)

    The other question I had was if I want to convert an mp3 to a video file like mp4 containing the audio from it, how do you best do that without lossiness? The mp3 is 320 kbps

    I assume if you just straight up convert it there will be compression, should I use Apple lossless to encode it or something? Should probably try it both ways and see if i can tell the difference

      If you have the original source and you want the highest lossy quality (I’m assuming because you didn’t say MP3, you said mp3 320), you should use the AAC low complexity setting (I’m using fre:ac to rip CDs) and jack the bitrate up all the way. It’ll be slightly bigger than the 320k mp3, assuming the same album art, but the quality will be much higher.

      You can use mp3 as an audio track in an mkv (and possibly other container files), though. I don’t see why you couldn’t. MP4 is just straight up video. I’m not sure what plays MP4 but not MKV, so I’d just use MKV with the audio track you already have.

      You can also use ALAC (Apple Lossless) if you like, or FLAC, if you really want that level of quality. I’m not 100% sure MKV supports them.

      Lastly, keep in mind MP4 is a video format. MP3 and M4A (or AAC), ALAC, and FLAC, are audio formats. MKV is a container format, so basically you dump a bunch of streams in it (audio, video, subtitles, chapters, etc.) and they just all come together.
