Video transitions Error ?!?

Hi,

If I take a footage.
I split it and I move the first part to the end.
I can't add transition between the two footages.
Is it someone have the same problem ? or it's "a bug" ?

Thanks

Did you check that there are enough handles to support a transition?

Try trimming a couple of frames.

Hi Johan,

Yes, the footage is long enough.
very strange
if you inverse the footage, It's doesn't work.
did you try ?

I just tried. It worked, but: I had to trim some frames at the end and the start of the clip. Prior to cut or after, that doesn't matter. Without trimming, there are no frames to overlap for a transition and it does not work.
I guess, that is, what Johan Hansson meant.
Or it is something about the footage. I took 4K mp4 footage from Sony FDR-AX33.
