To update this topic:

I've been recording a screencast for setting up a functional Org-mode
installation in Windows (I'll post about this separately), and wanted
to share the tools I'm using.

I did use recordmydesktop, and the Ogg Theora files it outputs had
some minor time synchronization issues. Nothing major, it "catches up"
frequently, but not real time keystroke capture. It runs in spurts.

I used Kdenlive to stitch together multiple segments, and found it to
be an excellent product, with terrible Ogg Theora support. To save
some time for the next person, here's what I did.

I took my .ogv's and transcoded them to .mov using ffmpeg, and split
the audio out to a separate wav file. Then Kdenlive used the .mov and
.wav in parallel tracks for rendering.

for X in *.ogv ; do ffmpeg -i $X -vn -acodec pcm_s16le -ar 22050 -ac 1
`basename $X .ogv`.wav ; done

for X in *.ogv ; do ffmpeg -i $X -an `basename $X .ogv`.mov ; done

After learning a bit on audio and video fades, Kden's rendering was
great. Always use at least a short audio fade in and out to prevent
clicks when changing tracks.

Next time I may use ffmpeg directly to record to avoid Theora, though
I think I'll continue to use my bluetooth headset with pulseaudio.

Thanks.

Re: [Orgmode] Org-mode screencasts

[Sebastian Rose]

Hi Richard,


great idea.

There are some screencasts around that could serve as a basis.  I'd
gladly rework my two little screencasts about org-protocol:

http://www.youtube.com/watch?v=h7Z2PiAcgh8
http://www.youtube.com/watch?v=G2xjwxEj-c8

I used Wink[1] to create those screnncasts.  But I guess it's not what
we should use (flash)?


To make all screencasts look the same, we would need to make them all on
the same system.  That's a problem.
For simple movies, just inside emacs, we could write an elisp file for
you to execute.  But as soon as other applications are involved, we'll
have a problem to solve.



 Sebastian

I can confirm this -- recordmydesktop is the tool I use regularily for
screencasts.

Re: [Orgmode] Org-mode screencasts

[John Hendy]

Maybe some help can be found here re. software?

- Big list: http://en.wikipedia.org/wiki/List_of_screencasting_software
- A bit dated, but pretty cool overview of some Linux methods:
http://www.linuxhaxor.net/?p=815
- Krut looks simple enough and has some neat features:
http://www.linux-magazine.com/Online/Blogs/Productivity-Sauce-Dmitri-s-open-source-blend-of-productive-computing/Krut-screencasts-made-easy
- This is recent and looks simple:
http://verb3k.wordpress.com/2010/01/26/how-to-do-proper-screencasts-on-linux/

I've never done this and so cannot really recommend anything in particular
from the wiki list... I did just try the last method (ffmpeg) and it worked
great. I don't have pulse audio at the moment, but tailoring their command
to this worked for me:

---
ffmpeg -f alsa -ac 2 -f x11grab -r 30 -s 1024x768 -i :0.0 -acodec pcm_s16le
-vcodec libx264 -vpre lossless_ultrafast -threads 0 output.mkv
---

Hope that helps even slightly... I didn't want to fiddle with the actual
"applications" right now, but I'm thinking that the ones with a spotlight
for the cursor and ability to zoom in could prove to be quite the nice
touch.

Perhaps we should put together "screencast wish list" somewhere? Then
perhaps individuals could sign up to work on them?

I think LaTeX integration would be a huge sell. I know a guy at work who
uses LaTeX for reports but has never heard of Org-mode. I, on the other
hand, only know about LaTeX because I found out about Org-mode. The more
I've learned how to use LaTeX, the more when he talks about things I can't
believe he's typing out all those lines for his reports! Showing how
Org-mode can take what you already know and make it that much easier and
faster to get work done would be neat, IMO.

Re: [Orgmode] Org-mode screencasts

[Richard Moreland]

I've just installed and tested "recordmydesktop" (based on Russell's
recommendation) on my Linux system and it seems to work great.  It
produces .ogv video files, which will need to be run through ffmpeg or
mencode first to be compatible with Vimeo.

On my Mac, I used Telestream's ScreenFlow, which has a great set of
editing tools built in.

I'd like to create a Worg page that will list:

- A link to each screencast
  Each screencast page ideally would contain:
  - Embedded video
  - Links to relevent documentation
  - Material referenced from the video (links to other packages, etc.)
  - Sample configuration files needed to achieve the results of the video
- Subject ideas
- Tools needed to record your own, where to upload them, etc.

I hope once we get one or two in there, it'll be easy for anyone else
who wants to contribute to follow suit.

I like the idea of using Vimeo since we may get new users who search
for "emacs" on that site.

So.. who wants to go first? :)  (Or if you don't want to do the
recording yourself, I'd be happy to work with you to come up with some
basic script for me to follow).

Re: [Orgmode] Org-mode screencasts

[Erik Iverson]

Richard,

First of all, your MobileOrg screencasts are very nice.
In my opinion, keeping things high-level and showing
the major features are what is important.  In a way,
they are commercials for the product, and I think the
best way to entice people into trying the product is to
make them say "Wow" when viewing the video.

I would be happy to help but would need to know the
software requirements.  Is it easy to make these under
Linux?

Re: [Orgmode] Org-mode screencasts

[Eric Schulte]

Hi Richard,

I think this is a really great idea.  I agree this could greatly raise
awareness of Org-mode and Org-mode features both for the completely
uninitiated and for the seasoned users.

We've been meaning to put together a Babel screencast, but as of yet
have not found the time or software.  Hopefully this will be the push we
need to either put together a screencast or send you a script with the
required documentation.

I've had luck hosting Emacs screencasts on vimeo in the past, it is
high-quality and easy to embed the vimeo-hosted video in other sites
(e.g. Worg).

Best -- Eric

What is needed? I've heard "recordmydesktop" works on Linux, but
hadn't used it yet.

[Orgmode] Org-mode screencasts

[Richard Moreland]

Hi All,

I think it would be helpful to create a series of screencasts to
demonstrate Org-mode.  The screencasts I've made for MobileOrg[1,2]
seem to have helped users get started quickly.  There are so many
powerful features of Org-mode that are difficult to visualize yourself
using until you can see them in action.  It may also help draw in new
users who otherwise wouldn't quite get it.

Some topics that may be interesting:

- Org-mode in action, demonstrating common tasks like capture,
restructuring a tree, refiling, etc.
- Babel
- Integration with other tools (Gnus, WL, Firefox, etc)
- Clocking/reporting
- Export capabilities
- Power user showing their streamlined configurations
- ...?

I'd like to collect all of the videos in one place, unify them with
some similar (but simple) production, with each of the videos having a
page that links to documentation, Worg, example dotfiles, comments,
etc to help the user take it further on their own.

I'd be happy to host the videos if bandwidth is a concern on the
orgmode.org site.  I've also already purchased the necessary software
to record/edit the videos.  But I'm looking to the community for ideas
on topics as well as individuals who would be willing to record the
videos or at least help me work up a script with key talking points so
I could do the recording and narration.
