Summary

0001929: Speed effect is very jerky in the interlaced video

Description

It seems to frames swapped wrong in the interlaced video. Due this resulting video is very jerky. Also, this speed bug i saw in the openshot video editor, which is using MLT too.

So i apologize that is a MLT bug or wrong settings are coming from kdenlive.

This bug relates to both speed up and slow down effects in the interlaced video.

Steps To Reproduce

Place to timeline interlaced clip and assign speed effect to them with any speed.
Render this. See result at any home hardware DVD-player.

Additional Information

Also, you can watch the result with a vlc player. Enable video deinterlacing filter "interpolate". See also attached video sample.
