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.

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.

  • We have reworked the underlying frameworks that make up the base of our products, due to these new frameworks / reorganizations - all localizations have been temporarily removed. We will be working with our localizers to being complete localizations in future releases. We didn't want to have half-baked localizations, and so decided it'd be better to remove them temporarily. Watch this space!

2.2.0(08 May 2011)

• Fixes

  • A number of stability improvements.
  • Fixed a bug causing iShowU to crash sometimes during resume of movies.
  • Fixed bug where sometimes the background QT process wouldn't start up, so thumbnailing would not occur.
  • Fixed a bug whereby the UI would appear to hang if you deleted a recording mid-resume.
  • Additional fix to resume that was causing a crash in some edge cases.
  • Fixed bug where you could not ctrl-drag the movie link from iShowU immediately after publishing. Now as soon as the link appears, you can.

  • Fixed choppy capture - rate smoothing is now ... smooth!
  • Fixed regression where the upload progress bar wouldn't go away after the upload completed.
  • Fixed issue where a capture could sometimes not be stopped.

  • Fixed issue with smart naming of recordings under Leopard.
  • Fixed issue with publishing names and naming of files under Leopard.
  • Finally found and fixed the bug causing HD to crash when you unplug devices (USB mics, etc).
  • Fixed various problems/regressions under 10.5.8 (especially related to PPC machines).
  • Fixed muxing of audio into 2ch (for various upload services).
  • Fixed Drag&Drop into the Sequence panel for Final Cut. If this is a problem for you, please go into General prefs for iShowU and disable the "Allow Control+Drag for movies" option.
  • Now saves presets on Quit (regression).
  • OCP fix - the correct URL is now available for dragging from the OCP manager if you change the title before the upload is complete.
  • Preset editor column sorting now stored, and correct default applied.
  • Resolved issue (2nd time) with warning message ("no active renderers") when waking from sleep.
  • Fixed issues with Preset Editor (headers now sort correctly, duplication of presets now also copies video settings).
  • Resolved a number of issues that could cause crashes.
  • Major Thumbnail Rewrite: Due to excessive instability with QuickTime, the thumbnailer has been removed and put into another process.
  • Fixed issue where resizing the window while recording could sometimes cause the recording to stop (especially noticeable in 10.5).
  • Fixed bug in countdown timer that could cause a crash if you did a retake while counting down.
  • Undo now works for deleting watermarks.
  • Resolving issues related to the preview, switching between screens, and changing monitor configurations.

  • Added additional safety to the MouseCompositor, addressing issues with changing mouse cursors in CS5 (again, I don't have CS5 so cannot test).
  • Placed additional locking around audio shutdown (hopefully fixes issues with MOTU devices - I don't have one so I can't verify).
  • Fixes to QuickLook under Snow Leopard.
  • Fixed issue in Disk Stage of Low CPU mode.
  • Fixed bug starting HD on 10.5.x systems that'd cause a failure upon startup.
  • Further locking fixes within audio, and some further tidy up's after thumbnailing.
  • Cleanups in the thumbnail renderer, lots of additional locking, much work around making capture lifecycle more robust.
  • Fixing registration system.
  • Fixed a serious problem that could cause out of memory errors and bad recordings.
  • Fixed the problem where compressing would never end.
  • Fixed color correction for Low CPU recordings.
  • Fixed recording in mono, so that it works correctly with other (non QT) players and also when uploaded to YouTube.
  • Sound recording is now more resilient if the sound source is interrupted often (as can be the case with digital inputs). A side effect is that recording will be more resilient under wider load situations.
  • Fixed issue with audio where devices with different sample rates could result in glitches when recording.

• Changes

  • Allow a user to change their One-Click publishing name (via the Menu in the OCP manager).
  • Easily edit the title/description when publishing. Enabled by default, can be turned off in prefs.

  • Drastically improved performance within the video bar (no longer crashes with 150+ recordings either) and fixed various selection problems.
  • A few missing localized resources were found and added.
  • A check is made for accelerated renderers before the app begins. This prevents needless an unhelpful crashes if you've no display connected.
  • There is now an option in preferences that disables "sleep" while Low CPU mode is compressing a video (so you can ensure your machine doesn't go to sleep while it's compressing, but does after it's done)
  • Added Undo functionality to the video bar when deleting videos. It'll now move them back from the trash if that is where they were put (or just put them back into the video bar, if you didn't move them to the trash).
  • Added Abort option to the status menu, and Edit menus. The dialog now no longer pops up if you are holding the shift key at the time you choose to abort (this mimics the behavior of iShowU v1).
  • Added option to edit the capture area to the Edit menu.
  • The Upload dialog now remembers it's state (title, description, keywords and last chosen category).
  • Updated the Russian localization.
  • Updated the Japanese localization.
  • Updated German localization.
  • *New* Italian localization.
  • *New* Spanish localization.
