Well, the codecs are not obviously already installed. A freshly sold computer does not come with the DivX/Xvid codec. You have to install it manually at some point.
I'll try and check again what is the minimum stuff to be installed on a virgin Windows to replay the videos.

edit:
So after some tests,

To play back AVI files generated by Kinovea in Windows Media Player on a fresh Windows XP machine:
- For Kinovea versions prior to 0.8.11, you need to install the FFDShow Tryouts codec.
- For Kinovea versions 0.8.11 and later you can either install the XviD codec or the FFDShow Tryouts codec.

The XviD codec is a single codec (small download), the FFDShow Tryouts is based on FFMpeg and will help decode many files. Although it works out of the box, if you need to configure it, the interface is more complex.
Both are open source software.

Oh, it looks like this was reported earlier in bug 217.

Can you please re-confirm that you do have the .NET 2.0 still installed on the machine, because it would seem that it is mandatory to have it installed.
The .NET 4.0 or .NET 3.5 alone are not sufficient.
(Currently the installation program only checks for 2.0 or later, it should be updated to mandates 2.0).

Ok, if it never worked it might not change anything but could you go to:

C:\Documents and Settings\[your user name]\Local Settings\Application Data\

(note that this is not the same place than the log and preferences files, it's under Local Settings.)

- Do you have a Kinovea folder there ?
- If so, does it contain one or more subfolders ? something like "Kinovea.exe_Url_zp3dzp…"

You can safely delete the whole "Kinovea" directory there, it will be generated back. Try to launch Kinovea again.

This folder contain a "user.config" file with some more info like the recent file history.
A problem with this file is the most likely cause of "Configuration system failed to initialize" error.

If it still doesn't work and the directory actually exists, try to get a hold of the user.config file (inside subdirectories). 
Please attach it to the bug 225 ("Upload File" section) or post the content here, thanks!

Newer webcams are capable of HD resolution, 720p or even 1080p… Maybe that's the way for the future…
However it would be interesting to know if they give good focus when the person filmed are more than a few meters away.
I see that logitech have some with Carl Zeiss optics.

I am also very interested in gathering as many comments as possible on this subject!

The trick is that the camera must be able to do direct streaming to the PC, which is a feature that is almost not included anymore in the new camcorders based on Hard drives or DVD storage.
I can see two options, DV / HDV with a Firewire connection to the PC (inbound Firewire on the PC also tend to disappear :-(), or a Webcam with a USB connection to the PC. (Maybe IP cameras should be considered too?)

I'm starting to wonder whether HD webcams are the future of capturing live direct to the PC. Not sure how their lens behave with outdoors scene with big depth of field though…

I'll look deeper into this later but as a start can you provide the Kinovea and .NET version ?
You may find this at the top of the log.txt file.

It is a strange error since Kinovea doesn't use a .NET config file.

Ah yes. Motion perfect slow motion, I've always been very impressed by their demo video.
On the suggestion / todo-list, I have referred to this as "Smooth slow motion".

This type of extreme slow motion by reconstructing missing frames from adjacent frames content would definitely be a killer feature and quite a challenge!

As far as I can tell this is extremely tricky to implement.
Also in the same vein, the Re:vision Twixtor set of plug-ins¹. Some say it's the best in the industry at this type of stuff.

I'm not too confident that I can code this all by myself to a usable result though hmm I have a few leads and reference papers but it's quite a long shot. Very interesting though.

Hi,
Thanks for the reports.
Which version of Kinovea are you using ?

The other problem is that it seems like comments are not saved unless I change the title of the comments.

This sounds a lot like bug 207 which should be corrected in version 0.8.9 and above.

I'll try to reproduce the crash.
Thanks

edit:
Reproduced the crash, added as bug 223

Yes, please send it smile thanks.

Best is a < 1.0MB file, without sensitive content, so I can eventually post it on the bug tracker for future reference.
(Please state if it's ok to publish it on the bug tracker or not.)

If it is indeed a similar issue than bug 214, then yes, the problem is during saving the file to MKV.
We specify the initial fps, for example 29.97fps, and it is somehow changed to 30fps (only some specific fps are subject to the issue).
The final video contains the same number of images, but they are not aligned with time anymore.

Seeing the large shift and the fact that it goes the other way, your issue may be a different one.
Also, if you didn't reencode the .asf and when reopening the key images are still offset, then it is definitely a different issue.

If possible, create a very short video on the camcorder, like 1 or 2 seconds, and do your conversion to .asf.
Then attach the .vob and the .asf to bug 214, or send them by mail to: joan at kinovea dot org. Thanks smile

Also, the .vob might be readable directly in Kinovea if it's an option.

Hello,
The IDE used won't be an issue as far as patches are concerned. There might be some extra changes in the project/solutions files, but that won't be an issue.

Personally I use SharpDevelop, others have reported that it rebuilt fine with VC#2008. I haven't tested with 2010 but I'm sure we can work out any problem if any.
Thanks for your interest smile

I don't have problems when checking out… Even as anonymous (I just cleared out authentication data to check, and I can still check out the trunk)

If someone else can give his/her experience ?
