Download Bilibili Multi-Part Videos: Chapter Navigation and Collection Discovery
Many Bilibili uploads are structured as multi-part courses, tutorial series, or creator collections. Our tool parses the complete chapter index, verifies the Content ID (CID) for your chosen part, and delivers clean MP4 video files with audio merged. If you only need to download a standard single video, visit our Bilibili Video Downloader.
Audio and video merged
Every chapter is delivered as a complete MP4 file with synchronized sound, avoiding silent video issues.
Collection discovery
Inspect public creator series, multi-video collections, and Bstation anime seasons in a single responsive interface.
A simple workflow
How to use this tool
- 1
Copy the Bilibili video link. For multi-part videos, navigate to the specific chapter (such as P2 or P3) on Bilibili so that the URL contains ?p=2 or the corresponding index.
- 2
Paste the URL into the input field above and click Get Video & Audio. Our parser scans the upload metadata to identify all available parts and collection items.
- 3
Select your intended chapter from the list, choose your desired video resolution or audio format, and click Download to save the file with video and sound merged.
Select and Download Bilibili Part P1, P2, and Collections: Technical Guide
Understanding how Bilibili structures multi-item content is essential for selecting and downloading the exact chapter you need. The platform organizes sequential media into three distinct categories:
| Content Structure | Technical Identification | URL Characteristics | How Our Tool Handles It |
|---|---|---|---|
| Multi-Part Uploads (分P) | Single BV ID containing multiple internal CIDs | bilibili.com/video/BV...?p=2 | Detects the p index and selects the corresponding chapter CID |
| Creator Collections (合集) | Series grouping multiple distinct BV IDs | Includes season_id or series_id | Lists all series episodes and lets you select any video entry |
| Public Media Lists (播单 / 收藏夹) | User-curated public video bookmarks | Includes fid or /list/ml... | Inspects the public list ID and exposes individual video links |
| Bstation Anime Seasons | Episodic anime series on bilibili.tv | bilibili.tv/en/video/... or season links | Exposes selectable public anime episodes for individual download |
Why Chapter Verification Prevents Downloading the Wrong Part
The most common issue users encounter when downloading multi-part Bilibili courses is receiving Part 1 when they intended to download Part 3 or Part 4.
This happens because sharing a video from the Bilibili mobile app frequently copies the generic parent URL without including the ?p=3 parameter. When a downloader receives a bare URL, it defaults to Part 1.
Our interface solves this problem by displaying the active part number, duration, and chapter title directly on the result card. If you notice that Part 1 is selected instead of your desired chapter, you can switch chapters directly using the on-page selector before initiating your download.
Audio Extraction and Subtitle Sync for Multi-Part Videos
Each part of a multi-part upload represents an independent media timeline. If you need accompanying audio or subtitle assets for a specific chapter, keep these technical details in mind:
- Audio & MP3 Tracks: Every chapter has an independent audio stream. To extract dialogue or lecture sound from Part 2, select Part 2 first and switch to the Audio tab. For dedicated audio processing, visit our Bilibili to MP3 converter.
- Closed Captions (CC): Subtitle timestamps for every part start at
00:00:00,000. Loading a caption file from Part 1 with a video from Part 2 will result in completely desynchronized text. Always export captions matching the exact chapter using our Bilibili Subtitle Downloader. - Thumbnail Cover Art: Standard user-generated multi-part uploads share one master cover graphic for the entire video upload. To inspect cover art, use our Bilibili Thumbnail Downloader.

Clear answers
Frequently asked questions
Can I download an entire Bilibili playlist or collection in one click?
No. Our tool displays all chapters and collection entries, allowing you to select and download one verified file at a time. This guarantees reliable file delivery with video and audio merged without browser timeouts or server memory crashes.
How do I download Part 2 (P2) instead of Part 1 (P1)?
Open the video on Bilibili and click on Part 2 in the chapter sidebar before copying the URL. The link will typically end in ?p=2. When you paste the link into our tool, verify that the displayed title matches Part 2 before clicking download.
What is the difference between a multi-part upload and a creator collection?
A multi-part video (分P) contains several chapters under one single BV identifier, where each chapter has an internal CID. A creator collection (合集) groups multiple separate videos, each possessing its own independent BV identifier.
Does this tool support Bilibili public favorites and media lists?
Yes. If a favorites list or media list is marked public by the user (with an exposed fid or ml list identifier), our tool inspects and lists the individual public videos. Private lists and Watch Later queues requiring account logins are not accessible.
Can I download anime seasons from Bstation (bilibili.tv)?
Supported public Bstation season and episode links display selectable episode entries. You can choose any publicly available episode to download. Region-restricted and VIP-locked titles remain subject to platform access controls.
Will downloaded multi-part video files have sound?
Yes. Bilibili delivers separate video and audio streams via the DASH protocol for every individual part. Our server merges the matching audio track with the video stream, producing a complete MP4 file with synchronized sound.
Can I extract MP3 audio from a specific chapter of a multi-part video?
Yes. After pasting your link, select your desired part from the list and switch to the Audio tab. You can save the original audio track or convert it to an MP3 file directly.
Can I download subtitles for a specific part of a multi-part video?
Yes. Each chapter of a multi-part video has an independent subtitle track. Select your target chapter and open the Captions tab to export SRT or VTT files for that specific part.
Why does the tool show Part 1 even when I pasted a link to a later part?
Mobile app share links often strip the ?p= parameter and copy the parent video link. If this happens, use the chapter selector inside the result card to choose your intended part before downloading.
Where are downloaded chapter files saved on mobile devices and computers?
On desktop computers (Windows and Mac), files save to your standard Downloads folder. On iPhone and iPad, check the Safari Downloads list and the Files app. On Android devices, files appear in your browser downloads and the device Downloads folder.
