Online Course Video Downloader for Offline Learning

Course videos on online education platforms are typically delivered via streaming technology, making direct right-click saving impossible. FlowPick helps you save purchased course videos locally for convenient offline learning or backup.

Supported Platforms

The following platforms have been community-verified to work with FlowPick for detecting and downloading course videos:

Platform Compatibility Notes

Not all educational platforms work with FlowPick. The following scenarios may cause detection or download failure:

Workflow

Step 1: Locate the Course Video Page

1. Log in to the course platform and navigate to the course detail page
2. Find the video lesson you want to download
3. Click to play and let the video start loading

Step 2: Detect Media Resources

1. Click the FlowPick icon in the browser toolbar
2. The popup window will automatically list detected video streams
3. If the list is empty, refresh the page, replay the video for a few seconds, then try again

Step 3: Select Quality

Course videos typically offer multiple quality options:

Recommendation: If the course contains extensive whiteboard content or code demos, choose 1080p to ensure text clarity. For lecture-only courses, 720p is sufficient.

Step 4: Configure Download Parameters

Step 5: Batch Download Courses

A course typically contains multiple video lessons. Use batch download:

1. Open each lesson page sequentially, play a few seconds to trigger detection
2. Each video will automatically join the download queue
3. Monitor overall progress in the download management panel
4. Verify file integrity after completion

FAQ

Can I download encrypted course videos?

FlowPick supports decryption of HLS AES-128 encrypted streams. If the course uses standard AES-128 encryption, it can be downloaded normally. However, the following cases cannot be handled:

• DRM encryption (Widevine, FairPlay, PlayReady)
• Custom encryption schemes
• Content requiring hardware-level decryption

What if download speed is very slow?

Educational platform CDNs usually have ample bandwidth. If speed is slow:

1. Check if concurrent thread count is too low (recommend 4)
2. Avoid peak hours (8-11 PM)
3. Check if local network has throttling

Downloaded video has no sound?

Some platforms use separate audio-video streams. If you encounter this:

1. Check if there's an independent audio stream entry
2. Download both video stream and audio stream simultaneously
3. Select MP4 output format; FlowPick will auto-merge them

Can't detect videos on some platforms?

Some platforms use special video loading methods that prevent FlowPick from detecting:

Best Practices

File Organization

Organize downloaded course files using this structure:

Course Name/
├── Chapter 01-Introduction/
│   ├── 1.1-Course Introduction.mp4
│   └── 1.2-Environment Setup.mp4
├── Chapter 02-Basics/
│   ├── 2.1-Core Concepts.mp4
│   └── 2.2-First Example.mp4
└── ...

Storage Planning

Backup Recommendations

• Verify files can play normally immediately after download
• Back up important courses to external hard drive or NAS
• Periodically check file integrity (some platforms update course content)
