Okay, may have had a breakthrough...
I use LiveGraphics quite extensively and recently created a new 32 layer LG.
It contains text layers and graphic layers.
When I have this loaded in Buffer 10 all is good. Add a second to Buffer 8 and it goes to ****.
I emptied all buffers and was able able to load an older LG into all 10 buffers without issue.
This new LG was fine up to Buffer 4 but jittery playback returned when I added to Buffer 5.
I get jittery video when only 2 are loaded, (Buffer 8 and 10).
Strange behaviour...
Just to add, this does seem to cause the jittery video and yesterdays broadcast was good as I dropped the LG and the recording remained engaged to the end but this does not cure the occasional video frame drop/catchup effect I see.
Also, this LG has 32 layers, is 100 frames long with a 5 frame loop in the middle.
Is this too intense for a TC2ELITE?
