Re: Outputing 1920x1080/50p
Thanks Ken Berry, but unfortunately many players are restricted to level 4.1, and 1080p50 or 1080p60 require level 4.2 of AVC specification, until new chips on players not arrive, we have that specification on paper only.

Re: Outputing 1920x1080/50p
Reading the various threads on this topic is a bit like Groundhog Day. It reminds me of digital still image technology 10 years ago, when there were discussions on why we needed to (or indeed if we should) move past 2.1 Mpx. Full HD is been available in consumer cameras for 5 years now. And full HD 50/60p cameras have been available for at least 2 years.
The full HD 50/60p threads that are more than a year old are largely irrelevant now, technology is moving on.
If optical disks can't keep up for video, fine. You can deliver 1080 50/60p files on Blu-ray or DVD as data. Also on HDD/SSD and USB-flash. That's nothing new. Last year AVCHD 2.0 was introduced adding 1920x1080 50/60p and 1440x1080 50/60p using MPEG-4 AVC/H.264 codec in a MPEG-TS at a rate up to 28Mbps. Even Sony is on board now, if a year late.

This even runs great on my modest 2core laptop, no stutter at 1080/50p.
This year we will see consumer cameras running at 35Mbps. And the low end professional cameras are running at 50Mbps and have been for years. High end professional cameras are running over 200Mbps onto SSDs. I don't want to hear about the problems going over 17Mbps.
So its no longer a question if it can be done, or its not necessary, that you should be happy with 720p or antiquaited interlace technology deveoped for CRTs. All we need now is to streamline the workflow, reduce the need for multiple passes & transcoding, apply more pressure on the NLE and optical disk vendors to get their gear into the here and now.
Computer monitors have already moved past 1920x1080. I can't wait for 4k 50/60p or even 100/120p and video-raw formats to reach the consumer markets. If the present state of art of consumer video is equivalent to still imagery 10 years ago, what's likely to happen to video by 2020? Its been defined already, even early prototypes - called Ultra High Definition Television (UHDTV). 7680 x 4320/120p with 12bit per channel, likely to be around 250Mbps compressed. This matches the quality of todays high end consumer still cameras. The coding may be H.265 (HEVC or MPEG-H). Time to play catch-up again.

Re: Outputing 1920x1080/50p
In this case is better to keep it with x264 in MKV container (wich have no restrictions), which plays fine in every software player, and some standalones, than pushing some updated standards,

Re: Outputing 1920x1080/50p
Thanks everyone for your help and guidance.
Workflow sorted. So relieved.
I'm getting good 1920x1080 50/60p output now. This is my reference master. Lots of oou's and ah's and stunning. But wait there's more ..
Here's a summary:
To get contemporay output formats from within VSP (and others) you need to add codecs, if you want to avoid a huge black-hole intermediate file and external transcoding. There are several choices. Pick your favorite. I've used the highly regarded x264vfw which installs painlessly and without side effects, but there are other options including the very popular ffdshow. You put the output into a custom AVI which allows you to select from the various codecs on your system and set all the parameters you need, especially 1920x1080 framed at 50/60. The resulting output file has essentially the same size, rate and quality as the original, and I get all the benefits of the VSP editor (and this great little camera).
From my "master", which is directly usable on many file based players, I can also externally transcode down to DVD and BD disks, also of very high quality. We are spoiled for choice here.
