New mechanism for tiktok without watermark

[Zipdox]

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');

@Zipdox , thank you very much. I don’t know if the python version is still needed, but just in case (skipped part with getting video URL from __NEXT_DATA__):

import io
import requests
import argparse

parser = argparse.ArgumentParser()
parser.add_argument('--video-url', type=str, dest='video_url', required=True)
args = parser.parse_args()

TIKTOK_GETTER = 'https://api2.musical.ly/aweme/v1/playwm/?video_id={video_id}'

with requests.get(args.video_url, stream=True) as response:
    response.raise_for_status()
    pos = response.content.find(b'vid:')
    bs = io.BytesIO(response.content)
    bs.seek(pos+4)
    vid = bs.read(32).decode('utf-8')

url = TIKTOK_GETTER.format(video_id=vid)
headers = {
    'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0'
}
response = requests.head(url, headers=headers, allow_redirects=True)
print('Output: ', response.url)

@Zipdox , @nuqz thank you very much, how to convert this code inside the Android Code without need of any API.

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

Thanks, now it works :) again

https://api2.musical.ly/aweme/v1/playwm/?video_id= is no longer working. Any fix

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

@hamaz562006 Tiktok was changed json data and remove videoId in comment metadata for new uploaded videos.
Old video: https://www.metadata2go.com/result/72f49335-c9d7-45fe-a360-be17a640e0a1
New uploaded video: https://www.metadata2go.com/result/5dc10484-a729-4a55-a838-52e615078dbd
I don't see Comment with vid in new uploaded video.

[khazidhea]

The "vid:" is gone from the file. Is there a new wait to get the hidden video_id? Services like https://snaptik.app/ somehow do it so there must be a way.

TikTok has recently stopped including it in videos. I guess they really don't like us removing watermarks. The TikTok reverse engineering guys are trying hard to figure something out without using the full mobile API but to no avail so far.
