H.264 High profile video that _plays_

Ok, here's something I did earlier from MKV to MP4 with Handbrake using these settings here http://forum.xda-developers.com/showpost.php?p=13411527

Hasn't turned out as smooth as I'd have liked, bit rate the issue again?

That should play fine, but while, since 3.1, we can play high profile it is at the limit of what the Tegra2 can decode realtime, if you want to guarantee smoothness and are encoding yourself I'd go for baseline profile.

I'll have a go with the baseline profile then. Hope it looks good. :D

Interesting. I used the Baseline profile for the same MKV.

Bigger file, higher bit rate than the high profile, but plays smooth as ya like!

I've tested out a hi def mp4 today.

Works very nice, didn't see any lag. Though I must admit, it is one of those "camera shake for effect" type movies, so maybe I'm just missing the lag! lol.

Anyway, here's the mediainfo details:-

So what program works best for converting MKV files to a format that plays perfectly on the stock player?

Handbrake?

And which profile/preset?

I use XMediaRecode (http://www.xmedia-recode.de/).

The homepage is in German. Just download it and it should start with you system language.

In this software there is a predefined profile for the Transformer. The profile uses Main level 3.1 with a low bitrate but you can adjust as you want and try out some more. I used as a test High level 4 with a higher bitrate. Makes the files bigger but if you use the HDMI port to a big TV then you will see a huge difference.

Looks pretty good - thanks for the link. It also looks like you can select audio / video / both to encode, depending on what the source file is.
