Hello,

I have on large clip in the Timeline, and multiple Title Clips, one after the other.
There is a gap between each Title Clip of two or three seconds.

If I do only render a selection, each Title Clip is working well. But if my selection reaches over two Title Clips,
only the first one is rendering correctly. The second doesn't appear.

Evey Title Clips uses the same png with alpha channel, and some Text layered over the png.

Sliding or Playing live shows all Clips correct.

You can download a small sample Version of this Project, with png and SampleClip here

Thank you for any suggestions or Tips how to solve this Problem.

Nice greetings to you all,

I have made some testing in the meanwhile.
It seems to have something to do with the keyframes in the Composite transition.
If I don't set keyframes to fade in an out the second clip appears normal. But I don't habe a solution so far.

[update 1]The second clip disappear even if I set a second keyframe at the end of the clip without changing the value.

[update 2]Another Test shows that only Text Clips are rendering fine and it seems to have something to do with the png Picture I have added.

[update 3]It obviously has something to with the png Picture. If I delete the Picture from the Title-Clip, after having trouble, all Title-Clips are rendering fine without it.

*I do actualize this Post, so nobody have to do same things twice ...

I have found a solution.

I finally used Gimp to convert the .png to .tif with Alpha Channel, and everything is rendering fine.
So my conclusion: Don't use .png Pictures written by Photoshop!

Nice Greetings,
