Option

 

Explanation

Crop

 

Will remove n number of pixels from a side, depending on which field a number is entered.

(Left,Right,Top,Bottom)

 

Crop values must be even numbers.

AutoCrop

 

By This File: Will find video edges (black bars, etc) and automatically set Crop settings for

 

 

all videos according to the selected file only. Automatic: Will find video edges (black bars,

 

 

etc) and automatically set Crop settings for each file during their conversions.

Size

 

Dimensions of the video in pixels. This setting will override any presets for each video type.

Framerate

 

Video frames per second. Film: 24, NTSC: 29.97, PAL: 25. This setting will override presets.

Preview

 

Shows a graphical preview of a frame n seconds into the video. Any settings such as Size

 

 

or Crop will be reflected here. Check “Show Compression” to view image degradation

 

 

depending on the format selected.

Bitrate

 

Data rate for the video. Measured in kilobits per second. Dialup: 56, DSL: ~1500

“Fit each video in”

 

Will calculate a Bitrate constrained to n megabytes based on the reported running time of

 

 

each video. Useful with the Two Pass option.

Two Pass

 

Will take a quick overview pass at a video to determine which parts need more resources to

 

 

encode. The second pass will encode the video using information determined in the first.

Force (QuickTime/ffmpeg

 

Chooses which decoding engine to use. Left alone, VisualHub will determine by filetype

Decoding)

 

which to use. Troublesome clips may benefit by the tweaking of this setting.

Deinterlace

 

Video from sources such as DV or DVD may demonstrate what’s commonly referred to as

 

 

“combing artifacts”. This setting will throw out every other line of video to combat that.

qmin

 

Chooses the minimum quantizer (quality) used. A high number (8+) will mean lower quality.

Extra ffmpeg Flags

 

Additional ffmpeg command line flags can be added here for very advanced users.

Audio Hz

 

Audio fidelity in Hertz. DVD:48000, CD:44100. Lower levels will result in lower audio quality.

Audio Bitrate

 

Data rate for the audio. Measured in kilobits per second. Standard MP3: 128

Audio Channels

 

Chooses between Mono and Stereo. Mono requires only half the Audio Bitrate to encode.

Volume

 

Amplifies or softens overall audio volume to n% of the original. A value of 0 means no audio.

VisualHub specifications

Apple VisualHub was a versatile multimedia application designed for Mac OS X, aimed at simplifying the process of converting video files into various formats. Launched by a small developer known as TechSpaghetti, VisualHub quickly gained popularity due to its user-friendly interface and powerful functionality.

One of the main features of VisualHub was its ability to convert videos to a wide range of formats, including MP4, AVI, MPEG, and more. This flexibility allowed users to prepare video content for different devices such as iPhones, iPods, and Apple TV. The drag-and-drop feature enhanced user convenience by enabling users to simply drag video files into the application for immediate conversion.

VisualHub was built on a combination of robust technologies, leveraging FFmpeg, a popular multimedia framework, to handle video processing. This underlying technology empowered the application to support a diverse array of input formats and deliver high-quality output quickly. Additionally, VisualHub utilized a streamlined codebase that optimized performance and improved conversion speed compared to many of its competitors.

Another noteworthy characteristic of VisualHub was its batch processing capability. Users could efficiently convert multiple videos at once, saving valuable time, particularly for those who needed to process large collections of video files. This feature, coupled with its intuitive interface, made it accessible for both casual users and more advanced video enthusiasts.

In addition to conversion, VisualHub also offered basic editing capabilities, including trimming video clips and adjusting audio settings. This provided users with some level of customization before finalizing their videos.

Despite its many strengths, VisualHub faced challenges, particularly as the digital landscape evolved with the rise of cloud-based services and streaming platforms. However, its legacy as a user-friendly and efficient video conversion tool remains recognized among macOS users who sought a straightforward solution for handling their video files.

In conclusion, Apple VisualHub was a significant tool in the realm of multimedia applications for Mac, known for its extensive format support, batch processing, and ease of use. While it is no longer actively maintained or available for purchase, its impact on video conversion software continues to be appreciated by those who utilized it during its prime.
