I get 650kb jpg pictures from AC4. You can send them to a PS Vita as a mail attachment, maybe you can save the original via that route?A friend just bought a Vita and I send him some screenshots, forgot to ask him if he can save them.

8 mbps real time encoded is not half blu-ray lol. Blu-ray runs at 24 mbps average, upto 40 mbps in heavy action scenes, multi pass encoded for best results. My HD video camera records in 24mbps, looks good, but blu-ray still looks a lot better.

The highest quality HD you tube video I've seen is 5.6mbps (Download via ps3youtube and you can see the average bitrate) I'm assuming they use multi pass encoding and variable bitrates so that should be good enough for an 8mbps real time encoded stream. Ofcourse I've also seen 1.5mbps encoded 1080p Youtube videos, quality varies a lot. Plus Youtube usually downgrades my videos to 720p, even though I upload in 10mbps 1080p.

It would be a great start if they allow you to copy the picture and video files to a thumbstick.

My tests was with RESOGUN... it is darker game so the JPG is small

I just looked at a list of bitrate of movies in Blu-ray forum... most uses 16mbps avg... so I said halt of the Blu-ray quality... or course there are exceptions with way better bitrate... I think 8mbps for PS4 really good (can be better but it is not bad at all... Xbone bitrate is 2-3mbps).

I don't have a Vita to make these tests... I think we need a option to export to PenDrive/ExternalHDD.

More services will be good too... Facebook, Twitter, USteam, Twitch are little for now... YouTube and others needs to be added.

You mean a list like this?

16 is at the lower end and more exception then rule. It's variable bitrate anyway, so a title like 2001 with avg 13.4 mbps still looks stunning since most of the movie is static or slow moving scenes, it's the ability to temporarily ramp it up to 40mbps that gives it a consistent quality during action scenes.
8mbps for real time encoding of 60 fps twitch gameplay is pretty low. Still pretty good for a console, with a decent h.264 encoder it should be able to match 15mbps mpeg2 cable HDTV quality, or double DVD quality.

Just let me get my hands on the original file to play around with in Pinnaccle studio.
