x264 AVC High@L5.1 to High@L4.1 conversion

[Pr0metheus]

Hi All,

I am using WDTV HD Media Player for playing movies, which has specification of supporting x264 video up to High@L4.1 AVC profile, but some of the movies I have are in High@L5.1 profile, which causing blemishes in the image during the movie playback. What's the best app to re-encode video stream from High@L5.1 to High@L4.1?

In case someone will need it, I've found it yet. XMedia Recode is perfect way to re-encode with various types of AVC profiles.

In case you want to change only the profile level, try H264LevelEditor.

It's free and can be found here:

tsmuxer import mkv> change 5.1 to 4.1 in level box select demux > remux mkvtoolnix

tsmuxer import mkv> change 5.1 to 4.1 in level box select demux > remux mkvtoolnix

tsmuxer level changer does the same as my H264LevelEditor, but requires three times as much HDD space:
- 1 for the original MKV
- 1 for the demuxed streams
- 1 again for the remuxed MKV

And also you must set again all tracks parameters before remuxing with mkvtoolnix (track name/language/delay).
H264LevelEditor works in-line on the source file, no copy needed .

Does not work for me on all 3 movies that I have tried so far. MediaInfo still reads as 5.1 and my LG still does not play. I will try to re-encode and post the results.

Thanks for the tool though.

EDIT:

A few hours later (after viewing the movie) I must say that depending on the file, simply changing the header wont do the trick. I had to follow dylz advice and re-encode. Does not take that long (45mins to get the file changed but it does need HDD space) and finally my file was playable on my LG 3D TV. The level changer is worth the try though, since it does change the header in under a second. If it works, then you're done.

Well, H264MediaInfo is just a shortcut for players that are mis-intepreting file headers, but it doesn't work for all of them.

tsmuxer level changer does the same as my H264LevelEditor...

Just a clarification, because I think that what I wrote is misleading.
I didn't mean that the two softwares do the same thing, I meant they try to achieve the same result with two different approach. tsmuxer follows the right (and slow + HDD consuming) way, mine is a shortcut with in-place editing.

The level changer is worth the try though, since it does change the header in under a second. If it works, then you're done.

You're right, thanks.
Latest version has an UNDO feature, so trying it is really safe now .
