Best Software For Putting Lectures Online? 126

An anonymous reader writes "I'm trying to help a school put their classes online in the way most minimally invasive to the teachers. A few environmental considerations: They don't always have live internet in the classroom, or I'd just run to Skype. I'm hoping to make it as much one-touch start/stop as possible to start recording, stop recording, and upload to a server. I'd like to believe others here have already done something similar, so if a package or process worked for you, that would be great to hear. Not sure what if it's all PowerPoint lectures, or if they actually use a whiteboard, and if so what the best camera would be to use (on a school budget!)."

      A similar option is Adobe Connect. My Statics/Dynamics professor, in addition to the regular in-class lectures, had a Monday night online-only lecture where he had a headset microphone and a Fujitsu convertible tablet where, via live screen capture, he worked out homework/review problems on our screens and talked us through it. If we had questions, we would type it into the chat area and he would answer them through the microphone. I don't know how expensive it is, though. (I imagine it's not cheap)

    Seriously, it is older and not supported anymore, but still works on modern OSes fine. Has a screen capture mode that works great. You start it and it just captures what happens on the screen until you hit stop. Very easy to use. Additionally, it has a codec called Windows Media Screen which uses compression well suited to static computer images. You can get a whole hour long lecture in like 30MB if space is a concern.

    You just have the instructor wear a mic that feeds in to the computer's input (if the room has sound reinforcement just split off a feed from that) and students get all their slides and what they were saying while they did it. Means they can run programs too and demo that.

    For easiest results, record in regular Windows Media format, which takes up way more space, but you can upload that right to Youtube. If you let them know what you are doing they'll let you have longer videos.

    In terms of recording whiteboards and so on, I don't know of anything both easy and cheap. An AVCHD cam does a great job, but you usually need to spend a little time in a video editor afterwards. There are some high end capture solutions, but as the term "high end" implies, you don't really want to know what they cost.

                    20% is FAR above their actual desktop market share. The figures I have from October 2011 put Macs at 6.45% (Windows is at 92.23%).

    As a starting point, make the actual videos downloadable or on DVD with a "quiz" style menu.

    Check out the Stanford On-line courses. http://www.db-class.org/course/auth/welcome [db-class.org] That's probably about the style you're looking for.

    Course Lectures split in to blocks of 10-15 mins each, with a small True/False or Multi-Choice quiz at the end. (you can do this with DVD's it just takes a bit of planning with the menus when authoring the DVD.)
    All supported by PDF of Teacher & Student lecture notes and examples on a single DVD.

    It is important to consider what you want in these online classes.
    • 1) Are you looking to make a course accessible after the fact, or do you want to do distance learning (which is what it sounds like when you say "I'd just run Skype") where interaction is possible?
    • 2) What types of courses are you making available? For example, some courses only need to a single camera on the teacher, other courses will need both teacher and/or power-point simultaneously, yet others will need video, chalkboard or whiteboard, and teacher, and others will also need the audience. Note also that some disciplines (math especially) use a lot of chalkboard, so you may need multiple cameras.

    These are nontrivial considerations, and often overlooked. I've been recording my calculus lectures at my university (Stony Brook), which has Echo360. Unfortunately, our setup is (a) expensive, and (b) useless for my discipline (mathematics), because it cannot capture 16 feet of blackboard in a way that can be read later, especially if you also sometimes use a data projector (which I do). It works fine for power-point oriented lectures, but you can't do mathematics properly via power point, because students need to see the problems being worked, and need to refer to the beginning of the problem (so it doesn't fit on a single slide).

    What has worked for me is to set up a pair of HD cameras in the back of the room, pointed so each can see (part of) the blackboard. Then I post-process this into a single video stream later. If I am using a data projector, I also grab the stream from Echo360. (I've also made multiple synchronized streams on a web-page using JWplayer, but this doesn't work as well)
    Unfortunately, this is not a turn-key solution.

    Something like matterhorn might be helpful too, but you really need consider all of the content needs before deciding on a delivery mechanism.

    • I've help some speakers record at a local place. We use one camera for recording straight into a laptop in HD. I ask for a copy of the power points on a thumb drive. Normally, I export the power points into PNG files. Then I can edit the whole thing in Sony Vegas overlaying the slides. It's more labor intensive than a set and forget solution, but it doesn't take that much work and I can typically edit the final video in less time that it took to record everything.

    "I'm trying to help a school put their classes online in the way most minimally invasive to the teachers." That guarantees a worthless product.

    Recorded lectures aren't that great to begin with. On top of that, most of the useful content is on the board or the slides, so you want a format which emphasizes them, not the speaker. A fixed wide-angle shot of the front of the room is almost useless.

    One little trick Stanford used for years was having presenters write on a paper pad, which was picked up by an overhead camera and projected to the students as well as being recorded. The pad was only 5" x 7", so that the instructor couldn't overfill a single page with more text than would survive mediocre analog TV.

      Exactly this. Our curriculum has included a particular lecture series for years. And, for the first several years, the faculty in charge of this series just offloaded the recording duties to random grad students... and provided us with several years of basically worthless video. Additionally several of them used a Microsoft piece of crapware that only worked in Internet Explorer and required all sorts of ActiveX plugins to allow the video to be watched... some sort of "MS Office" plugin that purported to ru

    At Michigan State University, we have a Techsmith Relay server. The instructor just puts in the USB thumb drive, the auto-run runs, and they just have to type in their lecture's name and hit "Start". It is recorded to the USB or automatically uploaded to our capturing server if they are on the network. It can automatically be pushed out to our LMS (Angel / Moodle), or posted on a webpage for people to access. Works on both Win and Mac, and doesn't need anything installed, which is super-nice.

    I've recorded a LOT of sessions with Camtasia as well. Great product, with tons of bells and whistles, but it does require the user to do the work of editing and encoding. That's great for me (I can edit it before I post), but not great for people who just want it to get out of their way.

    Also consider what to do for classes that do not use lecture much if at all. Many modern science classrooms use other methods, such as Modeling Physics [http]. If you were to video my classroom, you would need to be prepared to video student whiteboard sessions, lab demonstrations and discussion sessions, experimental design, experiments, data analysis, lab whiteboard discussions, and extensions such as worksheets, challenge problems, computer simulations and programming.

    I've worked with schools for years, and can point out some things that may help. First, if the school is in a poorer area, check out your E-Rate eligibility. In some cases, you can pay 10 cents on the dollar for technology. Among the eligible technology would be video streaming, such as vbrick.
    The vbrick units are highly scriptable, and you can ( and I have ) programmed them to do as follows:
    - user hits the button, as in a physical button on their desk or the wall or whatever
    - system records for x minutes
    - system uploads video to VOD server
    - VOD publishes video to public web server

    Yes, you can even have an "on-air" light turn on when the system is recording.
    Later on, you can add tags or other information on which people can search your content. You can attach documents, or links to other web-based content. So your video of a lesson has the associated homework, plus link to your states' DOE standards web site or whatever else you want. It can be integrated with moodle or similar systems. You can limit access to video by username/password and/or by IP address. If you want, videos recorded in the high school can be limited to specific users and/or IPs, so lets say the 2nd graders can't watch the sex-ed class. Likewise, you can limit videos on the public internet to your low bit-rate content only.
    The critical part here is ease of use. Teachers are asked to do more and more with no new resources. If your solution consists of login to this, click that, then this, etc.... it simply won't get used except maybe by a couple tech-savvy teachers. Of course when those people leave or change positions, your project dies. Then your well intentioned project becomes just another expensive boondoggle. In some ways, spending MORE on a project will guarantee success. Administration may let a 10K project disappear, but probably not a 100K project.
  • HTML is the way to go for the web. It allows hyperlinks and such fancy stuff.

Besides a very comprehensive grade school curriculum, the site has tools to support a teacher in finding out what students know and where they are having difficulty, so they can concentrate on helping a student where they need it most. As well, the Khan Academy has opened up public tutoring to give students the special support they need from people who've volunteered to teach. This is an amazing site and an incredible resource.

  • Unless the lecturers are willing to change their style quite a bit I don't think you'll do well without a cameraman in the room.
    In my experience lecturers move around quite a lot, and sometimes you need to pull back to get their body language, at other times you need to zoom
    in on the black- or white-board to see what they are writing or pointing at.
