Re: Deinterlace interlaced videos to 50 frames (1 replies, posted in General)
Oh, I didn't realize there was options, thanks for the heads up.
I'll try to look at this when time permits. If it's possible have a deinterlace mode that reconstruct full images from each field, then it will surely become the default.
edit:
The Yadif deinterlace algorithm is actually implemented in the new libavfilter library, which Kinovea doesn't include yet. The internal deinterlace will just reconstruct a frame from the first field.
There are other interesting things in libavfilter (notably the rotation filter) so sooner or later it will be included.

Re: Romanian translation for Kinovea 0.8.7 - it isn't too late, is it? (1 replies, posted in General)
Hi, thanks for your support.
I think it is best if you can concert and organize with Bogdan Paul Fr??il? for this, as he is in charge of the Romanian translation.
Please contact me by mail at joan@kinovea.org so I can connect you to him.
Regarding the release cycle and translation, it goes like this :
1. A version is release (say 0.8.7)
2. Development phase (as new features are implemented new strings are constantly added, removed, changed, so it's better to wait before translating them).
During this phase, experimental versions are released for testing, feedback, etc. (0.8.8, 0.8.9, etc.)
3. Feature freeze (no more features will be added for the next official release)
4. Translation phase (dedicated to translating all the new and changed strings since last official release, updating user manual, etc.)
5. The new version is released.
We are currently in step 2, closing on 3.

Re: Speed Presets in Replay and Delayed Capture (1 replies, posted in General)
Hi,
For the speed slider you can jump to the nearest 25% spot by using CTRL+Up arrow or CTRL+Down arrow.
I'll add the rest to the suggestion queue.
- A shortcut to change the live delay in capture screen. (could use the same CTRL+arrows to jump by 25% steps maybe ?)
- A shortcut to skip back in time a given ammount of time - (if currently playing keep playing, if not, stay paused).
Currently, the Home and End keys will jump to the begining / end of the current selection. Ideally, page up / down could have been used for jumping back/forth 5s, but they are already used to change the active screen when two screens. We may solve this conflict by expecting the CTRL modifier for one of the function… ?
Any feedback appreciated

Re: New feature : Observational References (19 replies, posted in General)
Yes, it will only consider files with the .svg extension for inclusion in the menu.
I see there is a check box in Inkscape's save dialog to "automatically add file extension", do you have it checked?
The menu will update in real time in the next version, by listening to changes in the "guides" folder.
(Also, semi-hidden feature discussed in page 1 of this thread, you can create subdirectories to group the files to your liking.)
What would be really awesome is if there was a central place where users could publish and share these files, and improve them by collaboration. And, it would facilitate diagnostic for issues related to them too.
I find the manipulation of the objects sub optimal though. (handles in corners often get out of the picture, dragging work only if exactly on part of the object, etc.)
If any one has ideas to improve the manipulation, don't hesitate !

Re: Snap to horizontal/vertical (2 replies, posted in Ideas and feature requests)
Ah yes, nice idea. Thanks for the suggestion.
I'm thinking maybe the Shift key modifier ? (I think it's like that in Photoshop and maybe other programs, additionally, Shift + free hand pencil will draw straight lines, it could be intersting too.).

Re: New feature : Observational References (19 replies, posted in General)
Thanks!
I'm having the same behavior.
When saving from Inkscape, everything looks fine, no error message, but then, when going to the actual location in Programs files through Windows Explorer, the file is not there.
(Although if reopening Inkscape save dialog, the file is visible!)
I think this is folder virtualization feature in the works as I suspected above. In Vista and 7, programs runs with normal user privileges (even on an administrator account) so when Inkscape tries to writes to Program files directory, it is transparently redirected to another, safe location.
The files are virtualized into %localappdata%/VirtualStore

Re: Use of X / Y coordinates for ? (6 replies, posted in General)
Using your single-frame-trajectory trick, you could define a "label" to identify them. (right click the track > configuration > label).
Displaying coordinates on single cross markers will definitely be in the next version. Thanks for the suggestion
(Added to the spreadsheet exporters too)

Re: New feature : Observational References (19 replies, posted in General)
Alexander, (or any one that had this issue)
Do you still reproduce this defect?
The program has to be restarted after the new file is added in the "guides" folder.
What about files added in sub directories?

Re: Speed selection 2 videos (1 replies, posted in General)
From your description, you have 2 videos of the same event, but they don't last the same duration. Is that right?
If so, it would seem Kinovea cannot parse the framerate of one of the video correctly.
When playing 2 videos, the program will use the framerate of each video independently and you shouldn't have to worry about it. (a 10-second scene will last 10 seconds whatever the framerate of each video).
In any event, I don't think you would be able to adjust the framerate mismatch by tweaking the slowmotion value (it will probably not be an whole number).
You can adjust the slow motion by 1% increments with the UP/DOWN arrow keys, but as you noticed, this change will impact both videos (it is a recent change, but it makes sense, the framerate should be irrelevant with regards to slowmotion, and we couldn't find real life scenario where one would need to compare a slowed down video with a real time one.)
Could you identify the one video that is not playing for the right duration? (It should behave like this even when played alone in single screen view).
With informations on format, etc. we can try to see where the problem is.

I am trying to track the bat path of a baseball swing, but I am not having any luck??? Is this possible to do?
I think you'll have to resort to manual tracking for this. The bat motion is super fast, and it is a rotation. It makes it very hard for the program to match the pattern from one frame to another.
You may have more luck by using stickers on the bat if it's at all possible. Not sure it will work due to the bat rotating on its own axis though. Manual tracking will probably do a better job anyway.

Re: Experimental version - 0.8.11 (11 replies, posted in General)
The framerate switcher will be in the next version. Hopefully the release will be on february 1st, if I can squeeze a few more bugfixes in.
With the current version, it will always take the first configuration that the camera driver exposes.
About the delay jump to slow motion, are you referring to playback or recording ?

Is it possible to build something like a trigger in kinovea? When I use the software my cameras are static so could it be possible to make something like:
if ( the golfball is gone)
keep on capturing for one more second
then playback the last 2 seconds
and ask if the swing should be saved". ?
Well, I'm open to this sort of stuff but so far all the implementations I have seen of this were pretty confusing in my opinion (in term of user experience / user interface). I certainly wouldn't want the casual user to have to think about how much preroll he needs to account for or force him to think in terms of predefined recording scenario…
With image size of the like of 640×480, you should have a pretty large buffer. If you can slide the delay to 30 seconds or something, that should leave you time to do the swing, go back to the computer and start recording. (You record what is currently displayed on screen, not the live)

I'm a new user and was wondering how the development of the motion tracking is progressing.
Hi,
The algorithm itself is more or less established (see similar snooker snapshot with version 0.8.6). There is still room for improvement, but it's considered of a lesser priority with regards to other areas. The next improvements regarding tracking will be the implementation of multi point tracking, to be able to track lines, angles, etc.

I'm trying the motion tracking with tracking a bowling balls path down a lane. I've noticed some of things you mentioned above like the tracking slowly shifts away from the ball or the tracking jumping off the ball to a reflection on the lane etc. happening. (I make manual adjustments to the track when this happens).
The issue with slow drift from the target and problems highlighted in the original message should be fixed in recent versions. (Unless you are using version older than 0.8.7) so it may be something special (like attaching to a small spot on the ball).
Attaching to reflection instead of the real thing is really hard to prevent. Sometimes the reflection just look more similar to the previous image than the object itself. In any case, the automation of tracking is really meant to be an aid to manual tracking.
bowl1820 wrote:
I was wondering if it would be possible to have a circular bounding box (preferably a variable size one(handles could be added to the box so as not to interfere with the manual dragging of the box.) that could be confined to the object being tracked) and/or maybe a way to highlight elements not to be tracked (like in part of photoshop they have a way to highlight areas to select and not select.)
The internal pattern window must be rectangular. I'm not familiar with this specific Photoshop function.
Hopefully, the ability to resize the search window should be enough to avoid these issues.
