New mechanism for tiktok without watermark

I found a new mechanism for downloading tiktok videos without watermark. I wrote a proof of concept in nodejs but I’m not too experienced with python so if anyone can help implement it that’d be great.

const request = require('request-promise');

async function downloadVideo(uri){
    // User-Agent is required to fetch the right page.
    const options = {
        url: uri,
        headers: {
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0'
        }
    }
    const videoPage = await request(options);
    
    // Extract JSON data from script tag.
    const regex = /<script id="__NEXT_DATA__" type="application\/json" crossorigin="anonymous">([^]*)<\/script><script crossorigin="anonymous" nomodule=/.exec(videoPage);
    if(regex == null) return console.error('Unable to extract data from page.');

    // Extract watermarked video URL after checking that the page is actually a video.
    const videoProps = JSON.parse(regex[1]);
    const videoData = videoProps.props.pageProps.videoData;
    if(videoData == undefined) return console.error('Unable to extract video data from page data.');
    const videoUrl = videoData.itemInfos.video.urls[0];

    // This is the magic trick. The video ID is hidding inside the watermarked video file. We can extract it by searching for "vid:" inside the video.
    const videoResult = await request(videoUrl);
    const position = Buffer.from(videoResult).indexOf('vid:');
    if(position == -1) return console.error('Could not find video ID in watermarked video.');
    const videoId = Buffer.from(videoResult).slice(position + 4, position + 36).toString();
    // You can retrieve the unwatermarked video with this URL and video ID.
    console.log(`https://api2.musical.ly/aweme/v1/playwm/?video_id=${videoId}`);
}

downloadVideo('https://www.tiktok.com/@user/video/id');

againt not working for some videos… url like https://api2.musical.ly/aweme/v1/playwm/?video_id={video_id} is still working for new videos, perhaps old videos moved to another data server url. Any one else decisions?

There has been a recent change. The API URL changed and you need a user-agent to fetch the watermarkless video. I wrote a userscript to download TikTok vids without watermark.

The gist is that you fetch the watermarked video, search the file for ‘vid:’ and copy Here’s a breakdown of how it works:

• Fetch the watermarked video
• Get the index of “vid:” in the file
• Slice the text from index+4 to index+36, that is the secret ID
• Fetch “https://api2-16-h2.musical.ly/aweme/v1/play/?video_id=`ID`&vr_type=0&is_play_url=1&source=PackSourceEnum_PUBLISH&media_type=4” with user-agent "okhttp
• That’s the watermarkless video

this method don’t work on some videoes (secret ID can’t be found) please fix
