iShowU HD Pro Features

Screenshots

• iShowU HD Pro screenshot - Camera overlay

  

  Include a camera overlay in realtime - position it where you want simply by dragging it about in the preview window. Border color and thickness can be changed at will.

• iShowU HD Choosing Capture Area screenshot

  

  Easily change the capture area. Either point at a window, or drag a rectangle around the area you want to capture.

• iShowU HD screenshot

  

  Realtime capture and on the fly GPU scaling. Nothing is faster than iShowU HD Pro. Multi track audio recording, GPU video scaling, watermarking and camera overlays.

• iShowU HD keystroke recording screenshot

  

  Make your presentations clearer by recording keystrokes and mouse clicks (mouse click animations not shown in above image). Mouse click animation color can be customized.

Comparison

¹ Keynote, Worlds of Warcraft, etc. iShowU HD will automatically capture the full screen when an application itself goes “full screen”.

² YouTube, Blip.TV and Howcast built-in.

³ Multi Channel Mixer. HD Pro lets you capture every audio channel independently (so if you want to remix just one later, that is possible).

⁴ In general, Final Cut prefers video with no “skipped frames”. iShowU HD Pro lets you specify whether or not gaps in a recording should be filled or expanded to fill the correct frame duration.

⁵ Low CPU mode is available for machines running Leopard or Snow Leopard only. Put another way, Low CPU mode isn’t available for Lion or Mountain Lion.

Upload scripting

It’s extensible

iShowU HD isn’t just limited to YouTube. We’ve included the ability for users to add further scripts with the intention of folding popular scripts into the product.

This page will provide a brief overview of the kinds of tasks required in order to create a new upload script.

For further information, we recommend going to the forums (there’s a specific forum for upload script development).

More detail

For the YouTube uploader, we chose Python for implementation. This is because it has a wide variety of third party classes available for various connection oriented tasks. Also, Dave likes Python :-)

iShowU HD presume that the script follows a certain “interface”.

iShowU HD (the UI) will call the script (the various —list-xxx commands) to gather information such as the media categories and what options are required / supported by the service being uploaded to.

There is further documentation available that describes the expected inputs and outputs to the script. Please read this to see what is expected.

Installation is a matter of placing two files in a known directory location. One being an image and the other the script. iShowU HD will automatically discover services when it starts.

Changelog

2.3.6(22 April 2013)

• Changes

  • Added the option to 'force mic audio to mono'.

• Fixes

  • Fixed problem where the first video recorded in a session would replace subsequent recordings. This occurred in some cases when the "Mix all audio to 2ch Stereo" was enabled in the QuickTime tab, or used via the context menu.

2.3.5(04 April 2013)

• Changes

  • iShowU HD disables LowCPU mode in the HD version (Pro version still has the option).
  • Better detection of accelerated renderers upon startup.

• Fixes

  • Fixed up the AAC warning message, which was displaying incorrectly when microphone recording was disabled.
  • Fixed up the YouTube script - it wasn't filtering out deprecated categories.
  • Possible fix for the inability to record video (i.e: some users getting audio only)
  • Provided error checking and automatic switching to PCM when the microphone device cannot be recorded directly into AAC.
  • Horizontal resolutions are automatically rounded up to a multiple of 32 when using Intel HD 4000 gfx cards.
  • Fixed typo in the user manual.

2.3.4(14 February 2013)

• Changes

  • Added a back-end feature to switch the ordering of registration checking (user vs shared) - useful if installing using images.
  • Added option to enable a more 'wordy' rendering of 'Tab', 'Option', 'Command', 'Control' and 'Shift' key presses.

• Fixes

  • Resolved an issue that could cause a hang upon starting the application.
  • Fixed issue where some people couldn't record in AAC - resulting in the "Compressing..." (forever) problem.
  • Fix problem with HD where it won't start if an non-accelerated (e.g: USB -> DVI adaptor) display is attached.

2.3.3(09 November 2012)

• Fixes

  • Fixed crash due to not having SF installed (sorry bout that).
  • Made handling of SF switching better. Now it only resets/switches when it has to.
  • Fixed crash issue on Mountain Lion when switching presets.
  • Fixed a couple of deadlock issues when switching between presets quickly.

2.3.2(02 August 2012)

• Fixes

  • Fixed issue on Mountain Lion whereby enabling/disabling microphone would cause a crash.
  • Fixed incorrect rendering of toolbar images on Mountain Lion.
  • Implemented a fix for the "1280x720 alternating" frame bug when using H.264 under Mountain Lion.

2.3.1(09 July 2012)

• Changes

  • Added feature: If drop-frames is enabled, it is only enabled when the mouse is not moving. Now, unless you've an explicit reason not to, you can leave "Drop Duplicate Frames" enabled in iShowU Preferences, and it'll 'Just Work'
  • iShowU HD can now make use of Retina displays when running on Lion or above. Capture will by default scale down the content, but if you choose to scale up (by say, 2x) then you'll see more detail in the final movie.
  • Added ability to drop duplicate frames under Mountain Lion.

• Fixes

  • Resolved issues with Retina displays (Lion only).
  • Fixed alignment and padding issues with capture under Lion, meaning that capture's exactly reflect the chosen/selected area now. No more 'one pixel' boundaries in final movies.
  • Fixed scaling/blur issue in Lion with Retina displays where you'd not get a clear image if you captured and area and had an output size of x2 (which is in effect a 1:1 capture for a Retina display machine). Now it's crisp.
  • Fixed up an issue with the most recent beta build not working on Snow Leopard.

2.3.0(18 June 2012)

• Changes

  • Now built as an Intel only binary, with a minimum requirement of 10.6.6.

• Fixes

  • Modified the 'do you want to remove the watermark' message to make it clearer when the preview isn't showing.

2.2.9(08 May 2012)

• Fixes

  • Support for Gatekeeper under Max OS X 10.8 (Mountain Lion)
  • Fixed issue on machines such as MacPro that'd cause Application audio to be routed to the internal speakers.
  • Fixed the 1422 fix. Sorry bout that.
  • Automatically increase relevant SF2ch channel/master volumes when enabling recording of application audio. Fixes problems related to not being able to hear application audio, when recording of app audio is enabled.
  • Further fixes to Localization.
  • Fixed potential crash under 10.5.8 when resizing the main window.
  • Fixed app not starting on 10.8 (Mountain Lion Developer Preview).
  • Widened a number of UI element to better accommodate non english translations.

2.2.8(11 January 2012)

• Fixes

  • Fixed issue with AppleScript integration where specifying a relative filename wouldn't work.
