Kinovea 8.15 and 8.26 report a different number of frames for the same video. It seems like 8.15 is correct and 8.26 is missing some frames. In 8.26 I get conflicts when exporting the video and the tracking data to Matlab.

The handling of timestamps read from the file was changed a bit in 0.8.27 to fix issues for some formats, please give this version a try and report if the problem is still there.

These issues are usually dependent on the file format or the encoder, could you send a sample file please?
