SUMMARY
Single track transitions reverse direction each transition

STEPS TO REPRODUCE
1. Use the single-track transition feature to transition from one clip to another.
2. Set the wipe file so that the transition is not a dissolve.
3. Repeat for several transitions.

OBSERVED RESULT
Direction of wipe alternates direction each transition.

EXPECTED RESULT
Direction of wipe remains the same with each transition.

Which wipe method do you use? I tested with "bi-linear-x" and the wipes work well of all same-track transition. Please try the nightly AppImage to see if it's solved in the meantime.

I am using the "linear_x.pgm" wipe included with kdenlive. First wipe goes from left to right, second wipe goes from right to left.

It does appear to be working in the latest nightly AppImage.

Thank you for the feedback. If it works correctly with the nightly AppImage then it's solved with 21.08.

I close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.
