Thanks John.
The Sony programmer admitted his mistake too so huge kudos to him for being honest.
I’m Chris, programmer for Vegas, first time posting to the forum.
Mea culpa. This bug was my fault. To ushere and others, I’m deeply sorry for this oversight. Nick Hope was right, it was the “% characters” crash fix that introduced this problem and we accidentally tested only stills, not sequences. We already have a new, fixed build in the pipeline and hopefully you’ll see it soon. Thank you all for posting about this because we were not aware of the bug until you spoke up.
This bug only affects image sequences, not other media files. I screwed up how we calculate the filename for frame N of the image sequence, and so we never find the right file. I hope you’ll forgive this error and will enjoy all of the other fixes we made in this round.
