Hi,
Yes currently the overlay of the other video is done "on the fly" during playback.
As noted elsewhere, this function might be superseded by a more powerful "aligned merge" but that's another sub project entirely.
However the general philosophy is that you should be able to export exactly what you see on screen, so I'll see how this could be done for the overlay. Now that the dual export function is in, it might be easier to implement.
Hi,
I wish this type of images to be called by their historical term of chronophotography. 
I had started some very early experiments at the begining of the year. It is a topic I'm very interested in.
However, it is obviously in competition for developpement time with other areas of the software, most notably stabilizing the capture screen, other middle sized improvements, fixing bugs, etc.
When the capture screen reach an acceptable level of stability, I would like this to be the next big work area. (Seamless merging of two videos over the same background is a related topic.)
It is planned for inclusion in the 0.8 series, but that doesn't say much about the timeframe.
Thanks
Bonjour,
Le script d'installation est basé sur NSIS. Il n'y a rien de particulier pour gérer l'installation silencieuse, je ne sais pas si c'est pris en charge automatiquement… (apparament c'est le switch /S en majuscule)
À vrai dire je ne vois pas trop le scénario ? C'est pour une installation en batch dans un script ?
(Sachant que normalement l'utilisateur doit accepter la licence d'utilisation du programme)
Hi,
This issue was solved recently and is available from version 0.8.8 forward.
You can get the latest experimental version from the pinned thread in the General forum (currently 0.8.9).
Bonjour,
Cela ressemble également a un bug rapporté sur le forum anglophone. Je vais essayer de regarder d'où ça pourrait venir.
Vous pouvez confirmer que vous utilisez une version de type >= 0.8.7 ?
Voir aussi le fichier de log (via le menu Aide), il y a peut-être des infos supplémentaires lorsque l'erreur se produit.
Very strange…
What is your Windows version, screen size, Kinovea version and system language ?
Can you see the entire dialog but the buttons are just not there, or is the bottom of the dialog hidden somehow ?
The full dialog should look like in this this screenshot.
4) Some other user accesses the original mp4 on-line through a standard browser (e.g. FireFox) and the on-line application indicates there is "Kinovea inside". If the user clicks that checkbox then the Kinovea overlays play. (So I think what this means is that there needs to be a special browser player to make this all work.)
Yes, it would mean programming a specific web player.
Technically it may be an interesting challenge, but I'm not sure about the added value: if you want to share a video with the drawings overlaid, you can save it in this way and upload it as is. If you want to share a bare video with the drawings as a separate file so the viewers can recombine them later, you can also easily do so (although the combination will have to happen in Kinovea).
Still, it would be interesting in regard to the key images positions and comments, things that are lost when simply saving with drawings painted on. But the web player would have to be capable of handling them.
I am going to focus on the desktop application, but if anyone wants to leverage the XML data in any way for web oriented usage, you're welcome. The format is hopefully relatively straightforward.
Hi,
Kinovea does not use external codecs, codec installation doesn't have any effect on the program, so the cause of the crash is most probably somewhere else. (haven't had time to look into it yet…)
(On a more technical note, Kinovea internally uses more or less the same code that is used by the FFDShow pack : both are based on libavcodec.)
Hi,
The current way to do this is as follow:
in the first video, do File > Save and choose "Save only the key images data." This will save your 4 drawings to a .kva file.
Then click on the second video to select it, and do File > Load key images data and open the file you just saved.
It has been suggested to have more "simultaneous effect" actions when working with two screens. (for exemple, the speed sliders are now locked together).
So maybe a special mode where any additions and modifications to drawings on one screen would be propagated to the other would be nice. That'd make this use case easier.
Since it crashes, you may have some "Unhandled crash" log files in the log folder. (You can get there from the help menu).
These logs should help understand what type of error is happening and which function is throwing it.
Could you paste the content of the last file generated in the bug tracker. (I assume you have created bug 211, thanks).
If you don't have the Unhandled crash log files, then keep the folder open, reproduce the issue, and copy the end of the log.txt file.
- In the platform Windows Vista the new version from Kinovea "hangs itself" when wou select the capture screen (with XP its works oke).
Ok. This may be related to the flickering issue reported by TeamTermin. I also experienced that with Windows 7 on a friend's machine…
- When you selected 2 capturescreens, recorded en switched back to 2 playback screens; the last 2 aren't displayed. You have to restarted Kinovea.
Yes, this should be fixed in the next version. Thanks.
- Is it possible to make a record button that captured both screens at the same time?
I think it is important that the capture works well for a single screen first
Ok, if the generated files does not play back in Kinovea, it is most surely an issue with the saving function.
Could you send me the generated files by mail (joan at kinovea dot org).
Some more infos will help:
What is the source of the original video ? (is it coming from a camcorder, passed through a transcoding program, from windows movie maker, from the web, etc.)
Could you also send a small sample of the original video ?
Were you trying to save a subset or the whole video ?
What is the duration of the video approximately ?
Thanks
The location from an observal reference in the preview is not the same with the location from the captured movie.
Currently we can't find out if the captured stream has rectangular pixels. (image format 4:3, 16:9, if different than the resolution).
Can you try to determine if this location problem is linked to this issue ?
Is it the same with other drawings or just the observational refs ?
Where is the capture option?
It is available in the latest experimental version (0.8.9)
Because of the start/stop nature of many sports (American Football) one needs a capture routine that automatically creates a new file every time the recording is stopped. Each new file should be named such that an alphabetical sort will keep them in the order recorded.
Yes, it was designed like that 
Basically, it looks for a number in the entered file name and increase that number to suggest the next file name. Hopefully you just have to hit rec/stop.
For exemple, if you set filename to "attempt 5", the next will be created as "attempt 6". (You can still manually change it if needed).
- If several numbers are found, only the last one is incremented.
- If none are found, a "- 2" is appended ("attempt" -> "attempt - 2" -> "attempt - 3", etc.).
Same applies for the image snapshot file.
Does the file play back in Kinovea at all ?
If not, there's probably an issue with the saving. What version are you using by the way ?
Hi,
"Error -2010" : Which player is giving this error ? Is it also Windows Media Player ?
Here is how various players should behave with videos created in Kinovea :
- VLC : should work out of the box.
- SMPlayer : should work out of the box.
- Media Player Classic : You will need to install a codec for MPEG4 ASP (for example Xvid).
- Windows Media Player :
1. You will need to install a codec for MPEG4 ASP (for example Xvid).
2. If using MKV container, you will also need to install the appropriate demuxer (for exemple, Haali Media Splitter)
It is also possible that the save failed and the file is corrupted somehow. Do you get the same error over and from different attempts, even with the codec installed or in VLC or SMPlayer ?
Can the file be read back in Kinovea ?
