If you're experiencing issues with the VideoProc Converter AI Downloader, the causes may vary. You might encounter problems like being unable to download YouTube videos, successfully downloading only some videos, downloading videos without sound, or issues with video playback. These problems can stem from various factors, such as compatibility settings, network conditions, or software configurations.

Some issues may be due to limitations on the video platform itself, while others can often be resolved with a few troubleshooting steps. In this article, we'll guide you through effective solutions to help you enjoy smooth, uninterrupted video downloads.

Problem Descriptions

"I need help with VideoProc Converter, it won't download YouTube videos for me. It says analyzed successfully, then says 'Start to download the video file, please wait. Writing thumbnail to c:/users/[my user name]/appdata/roaming/anvsoft/common/youtube/youtube-[some random letters and numbers.].webp'. It just stays in that and fails to download the video."

"I've downloaded many videos using this program in the past. Now it fails to analyze and I've tried reinstalling this Video Converter and changing the output directory but it's still the same problem. Does anyone know how to fix it?"

"I can't download from YouTube. The files end with .part, and they are not complete (14,9% or less). Other downloads at all. It happened all of a sudden."

Reason 1: Platform-side Changes

Platforms regularly update their functionality. These updates may affect the functionality of our software.

Please download the latest version of the software from our official website to continue using the application without interruption.

As always, our development team will monitor these changes and implement fixes as soon as possible. Once fixed, we will release updates to ensure the software remains stable and performs well.

We sincerely apologize for any inconvenience this may cause and appreciate your patience and continued support as we work towards improvements. If you encounter any issues, please feel free to contact our support team.

Reason 2: Unstable Network Connection

A weak or unstable network can interfere with successful video downloads.

Solution: Check your internet connection. Make sure it's active; if using Wi-Fi, try switching to a wired connection or resetting your router.

Reason 3: Python Environment Upgrade

On October 4, 2024, there were download issues all over the world. Fortunately, we have fixed this issue for Windows 8 or newer OS users. Python environment needs 3.9 or above.

Solution: We strongly recommend that you upgrade to the latest version of VideoProc Converter AI to use the "Downloader" feature properly on Windows 8 and later.

Reason 4: Windows Version Considerations

Due to changes in the Python environment, the download engine no longer supports Windows 7. This is a common limitation that affects many tools worldwide as older systems are phased out.

Solution: To use the "Downloader" feature properly, ensure your system is upgraded to Windows 8 or newer.

Reason 5: Redundant Video URL Parameters

This can happen when a user only wants to download a single video but uses a video address with a playlist suffix. VideoProc Converter AI may take longer to parse a playlist than a single video.

A typical YouTube video URL could be: https://www.youtube.com/watch?v=VIDEO_ID&list=PLAYLIST_ID

Also, using short links can cause downloads to fail. To avoid this, use the regular YouTube video link like this: https://www.youtube.com/watch?v=VIDEO_ID.

Solution: We've updated VideoProc Converter AI to resolve this. To download a single video instead of the entire playlist, keep the box below the video address bar unchecked. Conversely, check the box to download the whole playlist.

Reason 6: Age Restriction Prompts

Some videos have age restrictions that can block downloads.

Solution: Sign in to your account to confirm your age if you receive a prompt about age limitations.

Reason 7: M3U8 File Download Issues

Downloading M3U8 files can sometimes be problematic due to format restrictions.

Solution: If analysis of M3U8 files is successful but downloads fail, try downloading in other formats instead.

Reason 8: Regional Restrictions

If you encounter restrictions based on your location, you may be blocked from accessing certain content.

Solution: Use a VPN to connect through a different location, which can help bypass regional restrictions.

Reason 9: Account Login Requirements

Certain video platforms require you to be logged into your account to download content.

Solution: Ensure you are logged into the relevant video platform account before attempting to download, as this is crucial for accessing user-specific content.

Reason 10: Private Video Issues

Private videos often require specific permissions for downloads.

Solution: If you're trying to download a private video, make sure you are logged in with an account that has access to it.

Reason 11: Unsupported Websites

Some websites may not be supported by VideoProc, leading to download failures.

Solution: If the site you're trying to download from is unsupported, search for the video on other supported sites and attempt to download it again.

Reason 12: Antivirus and Firewall Interference

Antivirus software or firewalls may block the downloader from functioning properly.

Solution: Temporarily disable your antivirus and firewall to see if downloads improve. Some users have reported success after adjusting these settings.

Reason 13: VPN Interference

Using a VPN may cause download issues for some users.

Solution: Disable your VPN, as many users have resolved their problems by simply turning it off.

Reason 14: Robot Verification Issues

Robot verification can prevent video downloads, especially when using a proxy or VPN.

Solution: Disconnect from your proxy or VPN and try again. Switching to a different IP address may help bypass verification checks.
