MTS files don't work for me

[Gargo]

Hi,

I have premium Mezzmo and love it!
Up until now everything has played perfect on my Samsung C TV.
Well... to my problem! I just bought a Panasonic HD camera that records in MTS files. They work perfectly for about 20sec then the picture turns nasty and skip to next file. I wonder if you guys can find my problem?

To update the thread.
I have read on this forum that the preset of Samsung BDP can fix some stuff, so I tried it out. Now I get the timeline on the clips and they run to the end. But there is a new problem. They are very choppy in both sound and video.
Not watchable. I hope you guys can help me out.

Thanks!

Hi Gargo,

The bitrate on that MTS file is more than the TV can handle, thus it drops out. The stock "Samsung C" device profile should transcode such files, if transcoding is turned on. Is your transcoding turned on or off?

[Gargo]

Thanks for you fast answer Dennis,
I think my computer is to slow for good transcode. AMD Athlon 64 X2 Dual Core 5000+ 2,60GHz with 4gb ram. Don't you think?

[Paul]

Yes, that CPU won't let you watch such movies in real-time, but pre-transcoding (coming soon!) will help.

You can also start playing that file, then stop it and let background transcoding take care of it (don't play anything else, just let the server sit there and transcode in the background).

[Gargo]

One funny thing tho. When I edit the clips and make the movies, I save them in exactly the same bitrate with 5.1 sound, m2ts file. And my TV have no problem at all running this file true mezzmo. Odd?

This file is from my other camera. A Samsung HMX S15. It has even higher bitrate and 50fps. It's no problem at all running with mezzmo. No Transcode needed on MP4.

Thanks again Dennis for your help. I hope you will get back to me.

To add even more =/

I shot this clip at a much lower quality. Only ~12000 bits and its the same exact problem.

From my point of view its not the bitrate that is too high. It's the format or wrongly configured codec's? But I'm no expert =)

//Gargo

[Paul]

From the above, I'd say that the TV cannot handle bitrates higher than 9000 or so Mbits at frame rate 50, but can handle same bitrates at frame rate 25. The other file is an MP4, which is a completely different format, thus it's handled differently by the TV and plays fine. So, it's a combination of things, but from Mezzmo's point of view, more often than not, higher bitrates in MPEG-TS containers do not play (very often frame rates are high), thus it's safer to transcode all higher bitrates than to leave them as-is and cause the TV to stutter while playing.

[Gargo]

Thanks for clearing this up for me Dennis. I was under the assumption that bitrate was the law and format came second.

I bow for you!

Unfortunately things aren't that simple in the video encoding world - it's a nightmare actually I'm just happy to try and help out!
