New installation in Windows 7 Enterprise
Hi guys,
I have downloaded and installed V2.6 r294 and this app looks REALLY SLICK. I was able to get a nice quality screen video capture with audio working with almost no effort. Then came my effort to get the filesize down.
Here is what I ran into:
1) In changing the microphone audio settings, I found that the settings are not saved on exit as they should be. I cannot get it to remember my 11kHz 16 bit mono preference for instance. I made sure to launch the tool as Administrator and this had no impact.
2) Given that the UI works and video files are created properly, I guess I don't need to install the Visual Studio runtime libraries. But if I did need then, what version of the redistributable libraries would I need?
3) One of the instructional videos recommended installing VFW video and ACM audio codecs from the K-Lite Mega Codec pack (Full version), but that pack no longer seems to include the codes - at least by those names. What codecs should I use, and where should I get them?
FWIW, my goal is to create recordings of software demonstrations on my PC, so the screen content will changed fairly slowly, and phone-quality audio is just fine. As you can probably guess, the smaller the file, the better. I used to have access to a web collaboration tool that would regularly generate recording files for 60 minute demonstrations that were less than 100MB in size. Hopefully this tool can accomplish something similar...
Kudos on this great product and great support site - wish I was able to find answers to the above during my search efforts, and thus avoid bothering you.
Thanks for your time,
Andy

I recommend saving file size on the video portion and allowing the audio to be PCM audio (16-bit, 44.1 kHz) for the time being in order to hold the audio/video sync intact. One of my first videos was on the subject of sync, in fact! I tell just about everyone to use Jawor's Xvid http://jawormat.republika.pl/xvid.html because I have never had an issue with it and it compresses very cleanly (I typically use the 720 HD profile at quality of 1, but will be trying the 1080 HD profile in my next videos). Be certain to use the 32-bit versions.
I don't know about 100MB in size out-of-the-box, but I can recommend trying further compression AFTER you've made the video using tools like Any-Video-Converter http://www.any-video-converter.com/products/for_video_free/ or MediaCoder FLV edition http://www.mediacoderhq.com/flv-converter/ (which I use to produce MPEG-4 vids - see http://screencasttutorial.org/20/need-a-review-of-free-video-converters-and-encoders-576 -- there are many more helpful articles at that site as well).
Here is my playlist of videos at YouTube:

Oh, and I forgot to mention: You need the 2008 version of the MS C++ runtime libraries for 2.6b versions, and the 2010 version of the libraries if you install the 2.6c "next" version from our files section. http://sourceforge.net/projects/camstudio/files/next/

2.6c shows more codecs, and probably saves settings better, but I still recommend Xvid over the others and using MCI to record or PCM 16-bit, 44.1 [edit]kHz audio.
To really save file space on the video, cut down the playback rate, and save full keyframes less often. Here are the settings for just about all of my videos:
Set Keyframes every 200-300 frames
Capture Frames Every 100 ms
Playback Rate - 10 fps
Xvid compression, 720HD profile, quality 1
This with Use MCI to record produces solid-sync videos, but I do need to convert to MPEG-4 at 30fps to enjoy universal playback with all media players. I use Any-Video-Converter for that, typically, using its MPEG-4 Custom settings.
Keep in mind that YouTube requires stereo audio, just so you don't get bit if you intended to eventually upload to there.

I installed 2.6c (along with xvid) and indeed the settings save properly in Win7. I was not able to set keyframes higher than 200 and I assume you mean 44.1 kHz, not mhz for the audio, but things are looking really good otherwise. I am going to start with your settings and go from there - possibly even slower framerate and will also try the Any-Video-Converter.
The default playback came up with no picture, but Windows Media Player shows fine. Haven't tried classic yet but will. I'll be sure to post anything cool I might come up with.
Thanks again for the help!
Andy
Heh... yeah, I meant kHz!!! ;-)
You are correct about the keyframes - I was writing off the top of my head and couldn't remember the setting - just knew it was a very large number!
The default playback player included sucks - use anything else! And forget using the flash tool - it also is rather poor. Better to use Any-Video-Converter for that application.
Stay in touch if you have any more questions or solutions!
