<Subtitle>What is this player?</Subtitle>
<Paragraph>
This player is capable of simultaneously playing back a
lyric file (LRC), a main video/audio file, a SRV3 YouTube
Timed Text, and a backing audio file.
<br />
The idea is that this helps with not only karaoke but also
checking how well a LRC or SRV3 file syncs with the main
video/audio.
</Paragraph>
<Subtitle>How to use this player?</Subtitle>
<Paragraph>
You'll need to prepare a few files for the media you
want to play back first.
<br />
Theoretically you can mix/match any of the files below since
the main video/audio is all that's mandatory for
playback.
<br />
In this guide I'll assume that you're after a
karaoke experience, and want the works.
<br />
<br />
To add any files to the player simply drag it onto the right
part of the player page.
<br />
EVERYTHING IS RAN LOCALLY, NO FILES ARE EVER UPLOADED TO ANY
SERVERS.
</Paragraph>
<Subtitle>1. Main video/audio file</Subtitle>
<Paragraph>
Note: I've renamed the second button seen in the demos
from Video to Media to avoid confusion since it can support
audio/video files
</Paragraph>
<Paragraph>
This is the file that you want to play back. It can be a
video or an audio file.
<br />
Supported formats: mp4, webm, ogg, mp3, wav, flac, and more.
<br />
If you choose to use an audio file here, the right part of
the player will not show a video preview.
<br /> <br />A good way would be to download some video from
YouTube. You may need to make adjustments to the offset
later depending on how well the LRC file syncs with the
video.
<br /> How you do that will be up to you, but I recommend
using <a href="https://github.com/yt-dlp/yt-dlp">
yt-dlp
</a>{" "}
to download the video.
</Paragraph>
<Subtitle>2. Lyric File (LRC)</Subtitle>
<Paragraph>
This is the file that contains the lyrics of the song you
want to sing.
<br />
An example LRC file is shown below...
</Paragraph>
<Preformatted
dangerouslySetInnerHTML={{
__html: lyrics.replace(/\n/g, "<br/>"),
}}
/>
<Paragraph>
The player will highlight the current line of the lyrics as
the main media progresses.
<br />
If you need a LRC file, a good way is to rip it from Spotify
using{" "}
<a href="https://github.com/akashrchandran/syrics">
Syrics
</a>
.
</Paragraph>
<br />
<br />
<Paragraph>
At this point you should already be able to play back the
main media and have the lyrics highlighted as the media
progresses.
<br />
Depending on how well the LRC file syncs with the main
media, you may need to adjust the main offset labelled as
"Offset (±ms)"
</Paragraph>
<Video controls>
<source
src="https://files.catbox.moe/mfaei6.mp4"
type="video/mp4"
/>
</Video>
<Subtitle>3. Instrumental/Vocals (Audio 2)</Subtitle>
<Paragraph>
If you only wanted one or the other, simply add that as the
main media then you're done
<br />
There are a ton of tools online to remove this but
you'll want to make sure you get the instrumental track
in an audio format (mp3, wav, etc.)
<br />
Then hover over the right side of the player, click the
"Audio #2" button, and find your instrumental
track.
<br />
<br />
(TIP!) I suggest going back and setting the main media in
step 1 (Media button) in the previous step to a vocal only
video/audio.
<br /> This will make it significantly easier to offset the
2 tracks. You can always mux a video file on top of that if
you want visuals too!
<br />
Ultimately it doesn't matter which "slot" the
instrumental or "vocals" go into, it's just
better to have them separated!
<br />
<br />
Now adjust the offset using the numerical inputs, the
"Sync" button will adjust Audio 2 relative to the
main media.
<br />I suggest positioning the playhead at 00:00 and then
adding the secondary audio; this will make adjustments much
easier.
<br />
<br />
Now you should be able to control the balance between both
of these files (which one is louder) by using the slider!
</Paragraph>
<Subtitle>4. YouTube Timed Text</Subtitle>
<Paragraph>
If the YouTube video you downloaded has subtitles (sometimes
they look really cool and fancy), you can download that
using yt-dlp for use in the player as well.
<br />
<br />
Unfortunately there is no way to adjust the offset for this,
it'll play according to the main media.
