Re-watching my video, notice the audio is still sped up but the video is no longer. Pressing ctrl-z does not go back far enough so videopad screwed me once again 🙁 I did not make enough saves, and I should know better. Because you can not trust this program.
Update: I think this problem happened when I applied a colour temp effect to most of the sequence, but I am not 100% sure about that. I ended up deleting the effected clips and reinserted them in the timeline. After that I applied the speed up fx and colour temp fx. And all was fine again. It only cost me an hour extra 🙁
I thing I noticed; one of the effected clips was unlinked from the audio. But I could have accidentally clicked the unlink button. The clip next to it was also effected but not unlinked.
And, I have have experienced this issue, audio sped up and video no longer sped up, before. I hope the makers will find this problem, making v.p. a bit more trustworthy 🙂
