Hi,
You may switch to frame numbers for the time representation, that should take care of the problem. However, if the frame are really not evenly spaced in time, you will loose some accuracy.
In any case, when working with the spreadsheet exports, you should generally use numeric time representation like frame numbers or ten thousanth of an hour, etc. ("Total milliseconds" will be added in the future).

edit:
Looking better at your second example, yes, it would be possible to interpolate the missing bits, and even get subpixel positions. That deserves some more thinking

Ok, great.
I have started to fix the many interface issues related to this. Like options dialog, missing titles on drawing configuration windows, progress bar and others, the Working Zone selection bar, size of some buttons with images, splash screen, etc.
I'll try to work on this during september and fix some issues of the capture screen, and make a release for October 1st if time permits.

I think I have reproduced the issue. I went to the Windows' Control Panel > Display, and changed from "small - 100%" to "medium - 125%".

Then, when relaunching Kinovea… Wow. I get all kind of glitches in the interface
Including missing buttons on save and options dialogs. I posted a screenshot here.

Can you guys confirm this ? (That you have the option on medium or large).

Hi,
Can you walk me through this again, I can't wrap my mind around the issue. This is what I do:
- I close Kinovea.
- I Go into "Program Files > Kinovea > guides".
- right click on protractor.svg > select Copy.
- then Paste in the folder : a dialog box pops up "Destination folder access denied", You'll need to provide administrator permission…" I click continue.
- Other dialog box "Do you want to allow the following program…" > I click yes.
- the new file is created "protractor - Copy.svg". (108KB).
- I reopen Kinovea, launch a small video.
- Then I can see the "protractor - Copy" entry in the menu.

As far as I understand, the only way for the file not to be displayed in the menu would be that it's actually not really in the Program files folder, eventhough the file explorer makes us think so.
I don't have a Vista machine so this was done under 7.

The only thing I can think of right now is the file virtualization thing. When trying to write to a critical location (like "Program Files") the system detects you are a non-privileged user and actually pushes your changes to a special location under your own user files directory. It may does that transparently for you from the Windows File Explorer, but the files wouldn't be added to the right folder from Kinovea point of view.
(I'm not sure that's actually what is happening though).

If we could validate this hypothesis, I guess the best strategy then would be to use the Application data directory to store the user's .svg instead. (currently done for color profiles files)

Do you have anything under "C:\Users\[username]\AppData\Local\VirtualStore\Program Files\Kinovea\" ?

Hmm… And you can see the original ones, right ?

Can you remind your OS version ? Windows 7 ? And are you running as administrator or normal user ? (Will try to reproduce the context)

Ah yes, frame by frame and play have different behavior. When doing frame by frame, it seemed more sensible to actually move frame by frame in each video.
But I can see how it make little sense if the two videos have differing framerates.
Maybe both could be aligned on the fastest framerate of the two. If we have video A @ 30fps and video B @ 15fps, going to the next frame would move A by 1 frame, and B by 0.5 frame(staying on the current frame).

We can keep a counter to detect when the slowest video should advance one frame.
I'll add it to the suggestion queue
