720p turns out as 480p on my HD lcd on PS3??

[bagmand22]

Hi there. Sorry for my bad english.

I have a mkv-file and I would like to watch on my ps3 with selectable subtitles.
It works when I use TSmuxer to avchd and then burn the two folders in imgburn. UDF 2.50
But the problem is that when it pops on the screen the resolution goes down to
480p instead of the 720p. and gives a bad picture and the subs are very low in the picture
Although when I watch the file on my pc it´s still 1280x720p

What am I doing wrong?

Hard to say without knowing more about your set up.

How is your PS3 connected to the TV ?
What are your video settings in the PS3 ?
Have you tried Multi-AVCHD ?

I have my PS3 connected via HDMI to a 1080p HDTV. I use Multi-AVCHD to convert/author 720p mkv files and burn with Imgburn as UDF 2.50. These play back happily at full res.

[bagmand22]

Cool
Do you have selectable subs?

I have:
Philips 32" low HD 1366 x 768 p.
PS3 to TV with HDMI.
No have not tried that.

[bagmand22]

My PS3 video settings are 720p, 1080i and 1080p.
By the way the m2ts file plays fine on PS3 in HD, but
of course without subs.
So something happens when I mux it or burn it?

[guns1inger]

Yes, Multi-AVCHD gives you switchable subs, and a basic selection of menus as well (although the authoring tools is not very accurate and often does not pick the same frames when authoring that you see in the preview . . . )

[bagmand22]

Didn´t really work for me, but BDrebuilder works fine.
Im getting 720p on TV and the subs are fine.
Only weird thing is that I get a small green line in the buttom
of the screen.?
It is only when playing in PS3, not on my PC!

Any ideas what that might by?

If you're getting green lines when playing your movie on the PS3 then that means the source video is cropped and isn't taking up the full 1280x720 frame. I'm pretty sure your video resolution is only 1280x5xx or something like that depending on the aspect ratio. The green line at the bottom is a problem unique to the PS3 from what I've seen. It's just one of the ways it handles non-standard resolution movies in disc mode. I'm also pretty sure that this is also the reason why your PS3 was switching to 480p since your video isn't in the standard 720p resolution. The only way to get rid of the green section is to re-encode your movie and add borders to bring the actual resolution back to 1280x720.

[bagmand22]

Ok thank you.
Yes the video is 1280x533 as I remember.
Does BDrebuilder do the borders automatically,
or what program does?
I MUST have the switchable sub.

[guns1inger]

Again, multi-AVCHD can do all this. Load the mkvfile, then click on Edit, then Transcode. All you need to set is the encoding quality and the bitrate (the auto bitrate may be too high). When you author the new disc, multi-AVCHD will re-encode the video with borders, then author a disc.

The transcode engine has also been released as a standalone tool called uncropmkv, which has all the same features, but outputs an mkv file that is true 720p instead of an authored BD5/9

[bagmand22]

Ok cool, but the output file dosn´t seem
to be a BDWM and CERTIFICATE folder
but a BDWM and AVCHD folder.
How do I burn them+
Could you maybe make a mini guide to how I do
it in Multi Avchd? 4-5 steps! Would be really helpfull.
I have a mkv-file 1280x528 and one srt-file
and I would like it with borders and switchable subs
so it fits perfectly on my PS3 and 32" HDTV.
Thank you..

[guns1inger]

Load the mkv file into multi-AVCHD

Click Edit, then Click Transcode

Set an appropriate bitrate. I aim for a target size of 4200MB to allow for the (large) authoring overhead

Set whatever authoring parameters you need. I am not to happy with the current menu system, so I elect to have no menus.

Start the process, and select AVCHD for Bluray/DVD as the type.

When Multi-AVCHD is done, load the BDWM folder into the latest version of Imgburn, let it set everything for bluray, then burn.

QED

[bagmand22]

Thanks, that works just fine
Just a little bad that quality gets
more poor because of the
re-encoding.

There isn´t any way to get the
mkv to ps3 with switchable subs
and no green line, whitout
re-encoding then?

[guns1inger]

Nope. If it hadn't been cropped you could have done it, but because it has been cropped, it is no longer compliant. It is re-encode or live with the line.

What re-encoding settings did you use ?

[bagmand22]

Okay..
I used 1-pass turbo.
I know that the video could get better,
but I can´t wait 15-20 hours

[guns1inger]

Time for an upgrade. In a basic quad core, 2 pass HQ take around 4 - 5 hours

[bagmand22]

OMG, thats fast. I´m running
AMD dual core x2 5000+.
Is 2-pass HQ close to loseless?

[guns1inger]

Nope. Encoding lossy to lossy will always be lossy. H264 does have a lossless mode, but like all lossless compression, the file sizes are huge.

However the quality loss is a lot less with the 2-pass HQ encode.

I haven't yet tried the 2-pass VHQ encode - I have no idea how long that will take

[bagmand22]

Just one more thing:
Can I use Multi avchd whitout re-encoding?
Can it mux srt´s to the mkv without re-encoding.
Maybe this will help, instead of TSmuxer.
So I get 720p and not 480p.
