WDTV Live Plus does not support MTS?

WD Legacy Products WD TV Live & Live Plus

Hi,

My camcorder (Canon HF G10) generates video in AVCHD MTS format (1920*1440, 29fps). When I loaded a small clip of mts file to my WD TV Live Plus it played fine. But when I merged all my mts footages together into a large single mts file there was problem. It took a long time to load up the file, then, play for a few seconds and go into slow motion.

I checked the specifications of WDTV Live Plus and found .mts is not listed as the supported format. Is this the case? How do I watch my mts video losslessly on WD TV Live Plus? Any idea shall be highly appreciated.

Sam

It’s probably the profile, not the container. That resolution is too high to be L4.1

Thank you! Did you mean that the resolution needs to be below  L4.1 so that WDTV Live Plus can support it?

I will check the original .mts file to see if it is L4.1 above.

You also mentioned the container has nothing to do with the playback problem. I am afraid I cannot agree with you. 

I used a camcorder program (Final Mate) to merge and re-wrap the mts footages losslessly to the MKV container format but then found the MKV file played fine in WDTV. It seems WDTV Live Plus favors .mkv format more.

All,

        I have a similar situation as Sam, what he has been saying, I would agree.  Here are the media info:

p.s.: BTW, I use popcorn hours, Sony Blue Ray player with USB supports and they both play just fine with the MTS, just WD TV live can’t play.

Thanks in advance.

Sincerely,

Perry

That’s right.  1920x1440 is an odd aspect ratio and resolution.   1920x1080 is the highest resolution supported.

MTS and M2TS, as far as I know, are synonymous.

Hi TonyPh12345,

Sorry! I typed the wrong resolution. It should be 1440*1080. My apology!

I also have mts video in 1920*1080 (1080P) which is similar to Perry’s case: display aspect ratio : 16:9, frame rate:29.97fps,  format profile : High@L4.0.

The original MTS file does not work in WDTV Live Plus, but once I rewrap it losslessly to MKV container format it works and works well. Nothing changed but the container.

Tony,

           My camcorder record in FULL HD.  Canon HF G10 highest resolution.

MTS format.

thanks again.

any update?

Here’s what I’m thinking…

The specs say:

H.264 MP@L4.1 and HP@4.1 up to 1920x1080p24, 1920x1080i30, or 1280x720p60 resolution.

Your video is 1920x1080i29.7 according to mediainfo.

However, interlaced is a bit vague in both specifications.   I don’t know if WD is specifying FIELDS per second or FRAMES per second;  same with MediaInfo.

If MediaInfo is giving FRAMES and WD is giving FIELDS, then there’s the problem, because there are twice as many fields as frames in interlaced video.

In other words, if WD is indicating 1920x1080i30 is FIELDS per second, then it can only decode 15 FRAMES per second.  And if MediaInfo is reporting FRAMES per second, then that file has 60 FIELDS per second, which is 4x different.

Sorry, I don’t have a clear answer for you.

Tony,  Thank you first of all.  I think you may be on to something here.  If I remember correctly, I am recording the video in 60i mode.  Perhaps WD can’t handle?  However, if I repackage it into the mkv container (instead of mts), WD handles just fine.  It is so strange.

Sincerely,

Perry

Hi PerryC,

How did you repack mts to mkv?

I am experiencing the same mts playback problem in WD TV.

Hope you could give me some advice.

Thank you!
