I just installed BCC 5 AVX (in Avid Xpress 5.2) and I am having problems batch rendering (render in to out)... I have a chroma key timeline with multiple clips and 3 Boris effects nested on each clip (directional blur, chroma key & matte choker).
If I render each clip individually, there are no problems. But, if I render in-out, the render gets stuck on the first clip (the effect appears to render and if I cancel the render, the clip is rendered, but no other clips on the timeline are rendered). Even if I render in-out with only 1 clip selected, the render gets stuck.
I've attempted to reproduce the issue that you describe in your post however I am having trouble reproducing the problem. With that I'd like to ask you to contact our support department to see if someone from that team can assist you in discovering the cause and working out a solution so that the filters will perform as you expect them to. Please send an email describing the problem to firstname.lastname@example.org and someone there will help.
