WonderFox Free HD Video Converter Factory is a free Windows program for converting video and audio files, preparing clips for different devices and downloading online media. Its converter combines output profiles with tools for selecting footage, changing the picture and managing sound, so those changes can become part of the converted file.
Output profiles
A conversion starts with a source video and a destination format. WonderFox Free HD Video Converter Factory accepts files through its file picker or drag and drop, then lets you select an output from a library of formats and device profiles. MP4, MKV, AVI and MOV are among the available video formats, with encoding options including H.264 and H.265.
Selecting an iPhone, Android device, television or games console uses a prepared conversion profile for that target.
Resolution, bitrate, frame rate and aspect ratio can also be changed. Compression works within the conversion process: changing the encoding or reducing the amount of video data can produce a smaller file, while lower bitrate or resolution can reduce visible detail. The free converter does not impose a source-file size or duration limit and exports without an added watermark.
Trimming and merging clips
The Trim tool selects the parts of a source video to keep. You can drag the start and end markers beneath the preview or enter exact times, then retain that range as a clip. Repeating the selection creates several clips from one recording. The control works by collecting wanted ranges rather than directly deleting scattered unwanted sections from a timeline.
Joining works in the opposite direction. The Merge window groups selected videos into one output and lets you drag them into the required playback order. You then choose the destination format and export the group.
Cropping, effects and subtitles
Cropping changes the visible area of the frame, while rotation corrects its orientation. Effects and color controls alter the image before conversion, and text or picture overlays place an additional element over the footage. These edits are applied to the exported video rather than saved as separate graphics.
Subtitle controls allow external files such as SRT and ASS to accompany the video. Existing subtitle tracks can also be removed.
Audio outputs
WonderFox Free HD Video Converter Factory can convert standalone audio files or extract a video’s sound into an audio file. Its outputs include MP3, WAV, FLAC, AIFF, M4A, Ogg and Opus. Choosing an audio output for a video therefore produces a sound-only copy rather than another movie file.
Audio settings include bitrate, sample rate, volume and channel configuration, with support for configurations up to 7.1 surround sound. Built-in ringtone presets provide outputs for iPhone and Android. When retaining video, you can add an audio track, replace one or remove unwanted sound tracks before export.
Online media
WonderFox Free HD Video Converter Factory’s Downloader takes a video or audio page URL and analyzes the available downloads. You choose from the returned formats and quality options, select a save location and start the download. Available outputs include MP4, WebM and M4A, and the downloader supports sites including YouTube, SoundCloud and Dailymotion.
Where the source offers them, audio-track and subtitle choices determine which language or accompanying text is saved. Downloaded media can then be converted into another supported format or prepared through a device profile. Live streams and material requiring a login, purchase or subscription are outside the downloader’s supported access.
HD Video Converter Factory editions
The free edition includes both conversion and downloading. HD Video Converter Factory Pro adds batch conversion and removes the free downloader’s download limits; DVD ripping belongs to the separate DVD & Video edition.
