Would it be ok to have an option on trajectories to "Set the origin of coordinates to follow this track" ? (or similar wording)
(I don't know how hard it will be to implement, but that would avoid creating a new object / tool.)

I know this kind of trick is also used in pure mechanics, to express the trajectory of a point relatively to a moving coordinate system. (for example, the edge of a moving wheel relatively to the center).
(pyMecaVideo, for Linux, can do that)

In sports, this could be useful to express, for example, the hand motion relatively to the elbow, the elbow relatively to the shoulder, foot to knee, etc.

Regarding stabilization of hand held videos, I had started working on it from another approach. For the more advanced visual effects, the motion of the camera has to be computed from the way the background change over time. This can be used to align images over each other by reversing the computed motion.
It only works when the camera is looking straight ahead though, but it could be helpful.

I'm afraid I'm not sure what an "Origo" is tongue Can you elaborate ? The origin of coordinates ?

This has been implemented in the last version (0.8.12) - by allowing whole image dragging even at normal size (no zoom). (and application of the change for the copy on the other screen)
It is only active when blending between the two videos is active for now…

Also, currently you can't zoom out to less than 100%… maybe it is limiting the usability of the feature…
Thoughts for improvements ?

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.

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.

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 smile

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 !

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.).

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

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 smile
(Added to the spreadsheet exporters too)

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?

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.
