I've been doing a couple of test renders with my Go Pro HD Black with the new software and although I'm not having any problems up to the point of creating the video, once I play back the final video I get horrendous artifacting, the kind of thing you get on satellite TV during bad weather.
There is a distinct pattern to it, it seems worse in areas of the image that don't change frame to frame, and the whole image cleans itself up once every 6 seconds (at 30fps) which I guess must be a key frame in the mpeg file to reset any artifacting issues.
Certain parts of the image suffer more than others, but most noticeable is that if there is a lot of activity from frame to frame everything is stable, it's usually only when there is no activity the problem dramatically increases.
I've tried rendering in everything up to VHQ and every sequence has exhibited the same issue so far, I haven't had one clean rendered sequence yet.
Now this was all experienced playing back the video in windows media player, when I played back using quicktime the vide would just hang on the mpeg keyframes and then show no movement until the next keyframe. Eventually quicktime just hung and I had to quit.
Finally I tried using jRiver media centre and that has been the only player that has played back the rendered sequence artefact and fault free.
So it does not appear to be a problem with the source material, or LRT itself, but it does appear to be an issue with the rendered mpeg 4 video not being produced in a way that is compatible with all playback devices.
I'm using LRT3.1 on LR5. I was using the large memory version of LRT and 64 bit version of windows 8 & LR.
