Moyea Video4Web Converter is a feature-rich tool made to prepare media files for web compatibility, by turning them into FLV, MP4, 3GP or 3G2 format. It can also convert audio files to AAC, M4A or MP3 file type.

It's wrapped in a user-friendly interface that enables you to add as many media files to the task list as you want for batch processing, or to locate DRM-protected files automatically.

You can preview clips in a built-in media player and take screenshots, pick the preferred audio and subtitle track, add subtitles from file, as well as merge multiple files into a single one.

If you're not satisfied with the preset profiles, you can customize settings when it comes to the video codec, quality, size, bit rate, frame rate and aspect ratio, along with the audio codec, quality, bit rate, sample rate, and channel mode. New profiles can be created and saved.

Moreover, you can trim movies into smaller parts, crop black borders, adjust the brightness, contrast, saturation and volume levels, as well as apply text or image watermarks. 3D media content is supported too, and you can select between red/cyan, red/green, red/blue, blue/yellow, interleaved, and side-by-side mode. On task completion, Moyea Video4Web Converter can be instructed to immediately upload the new files to YouTube.

You can modify the default output directory, subtitles folder and encoding mode, disable deinterlacing and auto-checkups for software updates, enable MP4 streaming mode, change the screenshot format (PNG, BMP, JPG), or apply a proxy Internet configuration. These options can be restored to default anytime.

It consumed low CPU and low-to-moderate RAM during our tests. No error dialogs were shown and it didn't hang or crash. However, some conversion jobs took a really long time to finish, the output files had a larger than expected size, and the image quality was low. Plus, the tool incorrectly identified remaining time.

To conclude, Moyea Video4Web Converter appears to be a comprehensive and reliable video conversion tool, backed by approachable options and customization properties. However, it has significant stability issues.
