New, Improved Class Recordings on WiZiQ - for Premium Members

by Harman Singh
Posted on 16 November, 2009

We recently updated our class recordings for premium members. The new class recordings are in better sync than previous ones and also, screen sharing video recording too will show up now. As you all will agree that syncing of the white board area with the audio and video of the teacher (or students) is one of the key elements of a class recording to make sense, we too are focused on this aspect. To know more about these recordings and new features in it, you can read a blog post here: http://wiziq.typepad.com/wiziqcom/2009/11/wiziq-launches-new-and-improved-recordings-for-its-premium-membersperhaps-one-of-the-most-useful-features-on-wiziq-is-the.html

You can use this forum for further feature requests and comments on the new recordings.

George, our tech teach is looking into the recording you reported. We did find high latency in the class but still need to figure out the real cause of the sync issue. Although we are constantly testing, if anyone finds their recording to be out of sync, please do report.

Great news, Harman! I look forward to seeing the improvement.

We will test it soon with ETCon 03 :)

Thanks for the info George. I already thought about taping the ETCon with Camtasia during the event already. Saves time later on when cutting the presentations :)

These notes are from this Saturday's meeting/experiment

http://www.wiziq.com/online-class/202422-My-ESL-Friends-107

time 8:10 (08 minutes 10 seconds)
Begin first desktop sharing test to share how to use RSS feeds from WIZIQ
Note: it took about one minute to come up on attendee screens and recorded screen. However some attendees experienced longer lag times.

time 10:00
recorded viewing started losing audio, but I noticed that buffering was taking place.

At that point we also lost the "desktop sharing" window during recorded viewing. I then backed up the time slider bar (player control at bottom of recording) but could not recapture screen sharing window during recorded viewing.

Could also not move slider to later points in recorded session. So I closed out the window and relaunched the recording. This time I waited for entire loading process to finish before starting recording.

There was still a glitch at time 10:00 but after a short time of no audio everything looks fine.
NOTE: second viewing had no loss of screen sharing window!

I then tried to advance the time slider to a later point in the video. This crashed the recording again.

So I reloaded entire recording agian. Promise myself not to touch time slider bar (at bottom of recording viewer). At 10:00 lost screen sharing display again. ((New English word)) Fickle... this behavior is fickle... it is not consistent.

25:00 we left screen sharing, we now have a viewing window in synch with the audio during recorded video viewing.

27:20 found that neither word documents nor pdf documents with hot links still do not work during class nor in recorded viewing.

39:00
second desktop sharing test
during recorded video we begin to experience a greater lag in screen vs audio feed

48:42
player went into buffering mode...
when viewer continued it somehow jumped into desktop sharing. ((new English word)) Vexing, this viewer can be vexing. (like an eveil spell is cast or a jihn is at play)


54:59 third destop sharing test
this got the screens back in sync during recorded video but screen view of desktop sharing was not recorded after about 1 minute

Final note:
Issue may be that we are mixing too many applications during one WIZIQ session.

See the final note above?
"Issue may be that we are mixing too many applications during one WIZIQ session."

Once again I have to remind myself to 'Keep it simple stupid" (KISS)

We had to throw together a class very quickly so I had no time to get fancy.

Here is the link
http://www.wiziq.com/tutorsession/detail.aspx?id=913524C4223645EDB1DF6564AD0122C1

There were about 5 of us in the class, most had writing privileges and microphone. The only thing loaded into class was a document for discussion.

The recording played flawlessly, no latency and everything stayed in sync right up to the end.

Also the slider bar in the player (bottom of recorded viewing) could be used without fear of messing up any of the synching.

So, for right now, I would say, if you want a clean recording, remember KISS. Focus on a minimum of WIZIQ functions don't use technology and gadgets for their own sake. Focus on the material to be learned rather than all of the cool ways you can present it.

From second post above "Saturday meeting/experiment"

You guys have no idea how magical Sid and the Wiz team can be with tracking down issues after a session is over. I think he can even extrapolate what color socks I have on!

Anyway, for those of you geeky enough to try to figure out what the conversation (problems) were about in that experiment, here was Sid's reply to me via email:

SID :
Our technical team is working on resolving this issue which is making the screen share to stop.

GEO:
27:20 found that neither word documents nor pdf documents with hot links still do not work during class nor in recorded viewing.

SID:
We are aware that links do not work on PDFs and Word documents.

GEO:
48:42 player went into buffering mode...
when viewer continued it somehow jumped into desktop sharing. ((new English word)) Vexing, this viewer can be vexing. (like an eveil spell is cast or a jihn is at play)

SID:
Same kind of issue/scenario which caused problem around 10:00 minute this time making screen sharing video to load late, our technical team is working on this.

GEO:
54:59 third desktop sharing test
this got the screens back in sync during recorded video but screen view of desktop sharing was not recorded after about 1 minute

SID:
Currently screen sharing and video on whiteboard or external window cannot be played at same time in recording, so please use only one of the feature at a time if you are concerned about how the recording will look like. This issue would be resolved in upcoming releases.

GEO:
Final note: Issue may be that we are mixing too many applications during one WIZIQ session.

SID:
We are working on improving our recordings feature, we look forward to your valued feedback.

Regards,
Sid

This posting is normally found at my blog My ESL Friends which is a diary of the exploits and experiences for anyone at WIZIQ. I posted it here also to help you guys share in the learning curve a few of us are experiencing when we get together every Saturday on WIZIQ.


The recording seems to be a new format. I will be citing
references by slide number to take these notes for the
class/meeting. The class appears to be broken into 2
minute segments called slides.

slide 1
George arrives late for class (again), more on this
later.

slide 1-5 (5 slides x 2 minutes = 10 minutes)
introductions and commo (slang for communications)
checks.

Slide 6 Scope of class, and first tip. George arrived
late for class because he was fidgetting ( not sitting
still) and he accidentally turned off power strip. Tip =
Sit still or move power strip out of reach.
Note: that there is already a 5 second +/- lag in
whiteboard vs. audio.

Slide 8 Note that the "whiteboard" begins to move around
a lot. This due to allowing most attendees to have
"writing controls". While this can be distracting and
counterproductive , this particular class is for
experimenting and allowing newbies (slang for persons new
to a given group or technology) to experience the wiziq
platform.



slide 9-11 Tips and Tricks - Discussion of using the
pause/record function during class. Some teachers have
had good luck with it others not. It may simply be that
you must be sure that you press the record button after
pausing. In any case it would be good to experiment in a
"private test" class to be sure you are comfortable with
its functionality.


Note (slide 11 15 seconds in) also that some of the chat
begins to go beyond the expected extraneous discussion.
We begin to see there is an attendee who may be attending
with no interest whatsoever with the class' purpose.
George is completely oblivious as he is focusing on the
class. This is why it is nice to have a dedicated
moderator (Momen) to maintain minimal decorum.

Slide 12-16 Played with "upload from desktop" function.
Pictures from attendees were brought into whiteboard.
Note that when to many have writing controls it becomes
rather chaotic for all in trying to control whiteboard
viewing.
Note it seems that it would be desirable to ensure
students upload pictures of smaller size to allow for
easier presentation of several pics at once. By using
"selection tool" (most upper left arrow tool) you can
click and drag pictures on whiteboard.


Slide 17-19 How to upload content from your WIZIQ
content library.
Note that synching problem (Ben seems to talk out of
turn) was due to a problem during the class, not due to
recording. Ben probably had a long lag time due to
internet issues.

Slide 19-21 Marian shows how to upload your content
(docs, ppts, videos, etc.) from the WIZIQ dashboard, into
your "content library".
Note that George finally took away writing controls from
everyone so we could have a stable whiteboard. (oops, as
George was removing extra whiteboards he deleted Marian's
slide during his explanation ;-0 )

slide 22 Attendee misuses the chat box. Momen (moderator)
warns about behavior. George chooses to remind everyone
about etiquette for class, fortunately it stopped. I
think in a regular class I would have immediately blocked
that user.
Note, there will need to be a simple censure feature for
recording in the future at WIZIQ. Much like you see on TV
where offensive behavior can be blocked out in the
recording rather than having to delete the entire session
from the archives.

Slide 23-25 Discussion of Kirsten and the E teachers conferenece ETCon03 here is the link.

Slide 26-28 Discussion of wiziq and moodle.

slide 29 Exhortation by George to all attendees.
Particularly ESL students who think they are not worthy
to share due to their limited English.

Closing note: This new recording format is pretty nice, however the platform no longer takes on the form of the original class. As you may have noticed there were several times I drew arrows and lines to icons and tools during the class, they are no longer meaningful during the recorded viewing. This probably means that we will have to rethink how we want to relate to the "recorded viewing" audience. It seems that using the desktop sharing mode may be the most logical choice if we want to showcase a given feature/function.

On Tuesday I tested the "New and Improved" (sounds like a dish detergent pitch) recording feature at WIZIQ. It is better and I like it. I think you guys might want to follow the couple of glitches experienced. Here is the support request I sent to Sid (Mr Spock):

Class recording issues
http://www.wiziq.com/online-class/208723-English-Corner
Things started out well as far synching goes but throughout length of class synching became worse. I am wondering if it is because I left the video stream on?

Also an interresting oddity when viewing recording... at minute 12:00 we went to web page but in recording it did not come up. At 12:19 it comes up then at 12:24 it is gone again. Now look at minute 29:07 there it is! Next look at minute 37:08, we lose it again. Should I shy way from using web page viewer if I expect students to view recording? Thanks, George

What do you want to bet that it is something simple that I was doing?
Anyway, I will post Sid's solution here when I get it.
by George Machlan posted on 18 November, 2009
PS Kristen you may want to talk with the WIZ team about the synching issues. It seems that they can sometimes be acccumalitive. So if you are running a 3 hour session the littlest things may accumulate over that long of a recording. You may ask them if three one hour sessions may be a safer bet.

But don't take my word for it as I have been so wrong so many times about these geek issues, it isn't funny.
by George Machlan posted on 19 November, 2009
Sid and team fixed the web sharing issue here is the continued discussion:

Thanks Sid,
Web page comes in on cue and stays there. I notice that the websharing does not follow our movement within the page during class. This may simply be due to your adjusting the program after the event. But don't worry about that now, we will test it on Saturday and let you know if we think it is a problem.

I am still concerned about the lag (synching) of audio. We did not experience this during the actual class and it is confusing for the the person who reviews the material in recording.

I will check today's recording (English Corner) to check latency vs synching and let you know. I deliberately left the video feed on to replicate the same conditions. However I did not allow several people to share tools or mic (except Wang who moderates).
by George Machlan posted on 19 November, 2009
Here is another help request to Sid:

Sid,
Today's class looks much better in recording, I even tried the "pause recording" function which seems to work flawlessly.
Here is the link:
http://www.wiziq.com/online-class/208725-English-Corner
The latency issues continue though. The teacher audio (me) seem to accumulate over time. By the last 20 minutes of recording it is very distracting. Notice that I left the video feed on during the recording again. It remains in synch with student audio and white board. Only my audio feed seems to be out of sync with everything else.

Next class (Tuesday) I will leave video off and see what happens.

Thanks again for your help
George

Here is another oddity when viewing recordings:

During a session, invariably one of the students have a very low mic (audio) level. While just barely audible during the class everyone else sound fine.

When listening to the recording it seems the compiler brings that students audio up to a normal level. Unfortunately it seems that it raises all audio levels up as well. Now the main presenter audio level (me) sounds very loud (almost shouting).

I am not sure how to deal with this unless it is something simple like reminding the student to keep microphone (via settings menu) on automatic.
