Mobile Markets, Improved Layout and Firewall Detection

Posted on March 16, 2012 by

Today we’ve updated both the player and desktop with some new features:

Mobile Markets

When you visit a Parleys channel you’ll now notice (if available) mobile market links, these will take you directly to the related tablet apps.

For example if you visit the JavaOne 2011 channel (click image below) you’ll see that both the Google Play & Apple App Store links are available!

Improved Layout

The video/slides layout has also been improved and optimized to enhance your viewing experience.
The navigation buttons are hidden after 8 seconds, this way you can focus on the actual presentation.

Firewall Detection

The updated player now detects if you’re behind a firewall, switching automatically the streaming protocol.

Enjoy!

How are Devoxx talks post-processed?

Posted on August 27, 2011 by

In this tutorial you can see how we post-process (Level-1) Devoxx France talks.

Important notes:

1) both the MP4 video of the computer screen and speaker video include audio of the speaker.

2) And to make the post-processing easier both video’s should start at the same time.

MPEG-4 and H.264 compression using MPEG-Streamclip

Posted on May 20, 2011 by

At Parleys.com we strongly encourage you to use “MPEG Streamclip“, an awesome FREE encoding application (available for both Mac and Windows) which supports MPEG-4 and H.265 compression and much, much more!

What’s also a nice feature is that you can define the encoded file size, you should set this to maximum 300Mb for a one hour presentation.  This limitation is also enforced by the Publisher.

For Devoxx 2010 we used 800×600 resolution for the speaker video and 1024×768 for the computer signal (= demo’s), but variations are of course possible.  For example for the VMware talks we used a 1024×576 resolution of the speaker video because we didn’t have any demo’s.

Devoxx 2011 uses 16:9 speaker video, the frame size encoding is set to 1024×576 (unscaled).

For the audio encoding we suggest you use MPEG-4 AAC, Stereo 44.1Khz and 64Kbps.

IMPORTANT NOTE:  Make sure “Interlaced Scaling” is unchecked!

Tutorial: Post processing a QuickTime screen recording

Posted on March 1, 2011 by

During one of the Belgian Java User Group (BeJUG) sessions the speaker used QuickTime Player to record his own presentation.   Yes, the more recent MacBook Pro’s are powerful enough to record your screen, audio (using built-in microphone) and meanwhile do your presentation and demo’s!

The BeJUG hibernate 3.6 presentation by Emmanuel Bernard was a 2 hour presentation with two demo’s, the end result can be viewed HERE.

The recording used the default screen resolution from the portable which was 1900 x 1200 resulting in a 500Mb QuickTime MOV file.  After the presentation the movie was saved using the 1080p option.

The tutorial below shows you how to post-process this self made movie using the latest version of the Parleys.com Publisher.

 

Important Publisher features demonstrated in this tutorial:

1) Use the freely available QuickTime Player to record the screen and audio from the presentors portable

2) Extracting the sound (mp3) from the QuickTime movie using the Parleys.com Publisher (right-click option)

3) Re-encode the QuickTime MOV file to MP4 and change the resolution from 1900×1200 to 1024×768 (right-click option)

4) Create a two part presentation using the magical “Create two parts” feature (right-click option)
