AceThinker Video Keeper

AceThinker Video Keeper 2.1

Download online video files and convert them into formats of your choice. (See all)

AceThinker Video Keeper is an application that works as a media file downloader and video converter. In addition, it connects you directly to lots of trending video-sharing sites so you can browse your favorite movies, music clips, tutorials, and TV shows. Once the files are identified, you can download them with ease and save them into the desired format for offline playback.

The program has a clear-cut interface, divided into three modules. The Preferences menu allows you to tailor the app for your particular needs. Therefore, you can determine the download folder, set an alert tone to let you know when the download is over, start the download automatically when adding a new task, ignore videos smaller than a given size, and exclude specific media file types. In addition, you can set the maximum number of simultaneous downloads, the favorite video format and audio format, and the quality of converted files.

Downloading a media file is very easy. All you need is copy the file's URL and paste it into the program. The tool supports downloading multiple videos at once. You can pause a download task at any moment and resume it later, without being required to look for the video again. In addition, you can enable the high-speed download feature to complete the download process faster. Yet, you can neither schedule the download sessions nor set a bandwidth limit. Without such options, other processes running on your computer may be affected.

The Detect module connects you to media file-sharing websites directly from within the program. The list of supported streaming sites is comprehensive, ranging from most popular to less common websites. The program also works as a video converter. The files can be converted with ease into a format of your choice. The output profiles are conveniently organized by video and audio formats and by device names. Optionally, you can edit the video files before enabling the conversion. The editing features consist of trimming and cropping the videos, setting the speed and the volume parameters, adjusting the image in terms of contrast, brightness, and saturation, and adding watermarks and subtitles.

To conclude, AceThinker Video Keeper offers a convenient solution to download and convert online video files. This way, you can enjoy playing media files offline, at the comfort of your home or on the go, on Mac computers or on portable devices, in their original form or customized to your personal needs.
