I have made a video and inter-leaved jpegs with text titles, on same channel.
If plays back on Project monitor as if it would work fine.

Everything render out (incl text Titeles) but except the Jpegs, which it blanks out.

What is causing this ? I have watched and followed tutorial videos.

Thanks.

I assume the inter-leaved jpegs are the problems. Try with normal JPG or PNG.

Yes, you are spot on.
Converted to PNG at it works !!!

I do wish that DNLive warned me with an error about file format or something.

Thanks for helping me get a video done which was held up.
