Some things I would like to see:

Fix Frame rate, all our footage is 120 fps so changing it for every video is a bit of pain.

A Ruler tool: use object in image for scale? keep for the video?

Have an issue with text to stills when writing on screen then taking a snap shot or series the text is retained from previous still (as its a video commentary? IS it possible to take a still and then annotate?

Is it possible to retrospectively add an audio track? As we are filming at 120fps a 10 second clip is a minute when slowed so plenty of time to do voice over?

Would it be possible to have a branded and licenced version  with some custom tools added? And quite a few removed?

In my opinion this is a very specialized need… What might work would be to have some sort of "Advanced" panel on the preference dialog. I think it is similar to the case of always forcing an aspect ratio to bypass the autodetect, or to always forcing deinterlace. They would be grouped there. What do you think?

The basic ruler tool is the line tool with measure enabled. Then all other lines can be turned into rulers.
Another option would be to create an observational reference with nice graduations.
The third option will be to implement rulers integrated on the screen's borders.

What you can do to have the text visible only on the frame it was added is to disable persistence. You can do that individually through the right-click menu of the label, or you can set this for all drawings in the preference dialog, at Drawings > Persistence.

Not possible in Kinovea. You'll have to reimport the video in another software to do voice over…
The policy is that Kinovea must be able to completely support the files it creates, so this voice over feature cannot be added until audio is supported in the input video.

Not sure what you mean exactly by licensed. The license covering Kinovea is open source with a strong copyleft. Means that when you redistribute Kinovea or any derivative work, you must do so under the exact same license (the GPLv2), and confer the same rights to your users than those you got from it (including access to source code).
In a few month from now I might be available for hire to do this type of custom changes/enhancements, but not right now. (Not too sure about rebranding though).

The general motion with tools is to decouple them from the core, so that it's easier to add/remove them. The hardest part is done, they are already almost detachable.

Thanks Joan, if you de become available it would be good to look at the possibility. I'll have a play with the other bits and see what we think.

The frame rate thing is specific to our need but we would like to simplify the user interface and not need use of an advanced panel, thats the point of the rebranding and specialising of the software to this specific application. It would need to be very easy to use (I mean techno phobe proof, think great aunt/ granny etc needs to use it!) WE may well be dealing with people who have a PC but dont know the difference between windows media player and itunes!

BEen playing with the 2 screen option and syncing the video, could we have a speed control added to the common controls? also getting a bit of an issue with our high speed footage. Is there a way to write both screens to a single output video to show a side by side comparison as an .avi or Mpeg etc?

VEry interested in having a custom/skinned version of kinovea available.

OK since learnt that our capture device writes the avi file header at 30fps explains a lot! Been looking at Dartfish and this has the "pause on navigation point" function which allows the footage to be stopped at relevant moments

A very nice feature of some of the licensed motion analysis software is a one touch capture.  For instance when filming a baseball or golf swing, you simply use one keystroke at the point of contact and the software pulls the previous 2 seconds and the next 1 second for a finished 3 second clip.  This is a nice tool for coaching because you are able to carry a mini keyboard and simply hit a function key when the student contacts the ball.  You are not tethered to the computer and the video is already clipped.

I agree, this would be a very useful feature for recording videos. It would make capture/recording more user friendly.

This probably will be one of the many things on the 'to do' list tongue

I wonder if could be possible to add a new tool in Kinovea to rotate video / imagine 90 degrees.

So I could do a video with camera in vertical positon and then adjust it with Kinovea.

Hi Joan did you get my email? After looking at other offerings in the market we would like to discuss the possibilities with kinovea in more depth.
