1080p60 (1080p50) playback - Page 2

I found images in the user manual that probably mimick the actual UI. It looks functional although fairly spartan compared to WD Live Hub, let alone the fancy UIs of Plex, XBMC, and similar programs.

The UI is the same as on the -83 and is illustrated in the online manual. Not so good for large collections.

I have the Sony BDP-S570 with firmware M04.R.735 and burned the iso to a DVD-RW. It played very nicely and I was stunned by the great quality of that final clip.

Also: The audio on that final clip switched my Onkyo 905 AVR to "MultiCh" mode (from "Direct" for the other clips) and lit up all the audio channels, whereas the previous clips only lit up the Front Left and Front Right channels. That final clip is the only one that appeared to be surround sound.

The LG BD570 plays every clip without stuttering. However, skipping forward between the tracks was not working very well but it would fast forward fine.

Any chance of trialling the clips over network?

I don't know of a DLNA server that supports AVCHD. Conceptually a directory structure with auxillary file types is more complicated that a single file and I'm not sure how a client and server would work it out.

[EDIT: the OPPO supports individual m2ts files and that could be tested over DLNA, but that's not the same as full AVCHD].

-Bill

Individual clips would be fine. Many thanks.

In my setup with the OPPO BDP-93, ethernet cable to my linux PC running Twonky for DLNA, all the individual m2ts files play, but they all stutter. Would a different server produce better results? I don't know.

I copied the m2ts files out of AVCHD to a bare folder on a USB stick and they all play smoothly when directly mounted on the player, just as the AVCHD version itself does.

Thanks for testing. I edit all my 1080p60 and render to single .m2ts file in 1080p60 and play back over network from NAS with Dune. I am looking for a BD player in another room which can still stream the files OK. Might have to do some more searching or end up with another Dune.

I cheated and used my pc to play these, but that 1080p60 looks sooo good.

I've never been able to play any BD-25, authored with multiAVCHD, on my OPPO-93, latest firmware. They were all "Unknown Disc". I've certainly made sure to try multiple settings with no avail. When using BD-Rebuilder, all DVD5and9 played fine but no BD-25 with full backup mode! I am puzzled. Any parameters on the player ? Thanks for any hints.

Are you talking about burned discs? Or playback off an attached hard drive? Or streaming via DLNA?

DLNA will have problems with AVCHD.

For burned discs, the particular media and the speed at which you do the burn are the usual factors. Give Oppo tech support a call. They may ask you to send them a disc so they can see what's up.

For hard drive playback, embed the BD folder in a folder named AVCHD and play that AVCHD. The 93 won't play direct copies but you can get around that this way by playing them as an AVCHD.

Thanks Bob for taking the time to answer. I've read a lot of your posted messages and it must keep you very busy. But your knowledge is evident and your suggestions had helped me a lot.
Regarding my issue, I was taking about burned BD folders created by multiAVCHD or BD-Rebuilder on 25Go Memorex BD-R, at 2.4X. Playing m2ts files through an external drive, worked flawlessly but it is not like a BD burned disc. I've just read about the AVCHD folders and I will try to embed BD folders ion it. Will this give me access to original menu, chapters, etc. ?
BTW, I've downloaded the 336 Mo ISO and all 5 files played correctly. I'll give a call to OPPO. Thanks.

Yes, the AVCHD hack works quite well so long as you are not trying to stream the results.

You should also try posting in the Oppo owner's thread as you are more likely to have your post read by people trying to do the same thing.

I will post this message in the Oppo's owner thread, I just wanted to avoid a double -post. Thanks for your help and remain a dedicated ressource.

Just tested my older LG BD350C. (latest firmware applied). It plays 1080p60 from DVD well with rates up to 18 MB/s. At 28 MB/s is completely unwatchable, it stutters badly. I burned a RW bluray disk (as AVCHD with mAVCHD) 4 different clips at 1080p60 28 MB/s and plays well. There is one exeption, I will have to investigate more from where it's comming. One of the clips is longer about 6 minute total. After about 2 minutes I had imprssion that it was some short stuttering, but after that all was OK.I have to try the disk on PC and double check that the stuttering is not from recording. The other 3 short clips I had about 1-2 minutes long play OK. As a note for blu-ray I did not use the clips provided but new ones I found on the net recorded with Sony NEX5N (1080p60, 28MB/s - AVCHD2.0 progressive).

OK, I had time to investigate.It looks like the problem is with mAVCHD processing, not with the player. I tried to play the generated stream file on PC, from harddrive and there is the same stuttering. In the original file all OK. The program I use (mAVCHD) does not d any transcoding (I can check the detailed of the file it's still 1080p60, ~28 Bits/s, but for any reason it stutters and original one does not. I'm not an expert on mAVCHD so I can not tell why.
I will try to play with some settings.

Can anyone point out a specific 2011 or 2012 Blu-ray player model that has a spec list that specifically affirms it will play discs that use the AVCHD 2.0 codec, which entails 1920x1080 resolution with 60p/50p at 28mbps?

Or how about a link to the specific area of a manufacturer's site where an owner of an existing BD player can download a firmware update to enable it to play such discs?

Neither item is a cinch to find. There are assorted rumors, or threads that raise the issue, but then peter out. But no real deal. The Sony and Panasonic global sites are not any help, and I suspect that the other manufacturers' sites are mute or oblique. SFAIK, there is no 1080 60p content for sale, but the number of cameras now sold with an AVCHD2 mode would seem to call for some dedicated player support. Otherwise, the stuff must be converted or else watched only on one's own PC.

I've searched many forum threads for this topic, but it does not appear in the subject line of anything in this section. I see it mentioned in some PS3 threads, or in others that relate to Sony or Panasonic cameras that shoot in that mode. Evidently, the latest versions of Sony editing products, or Avid Studio, can import and export the video without downconversion. Some threads allege that some 2011 models of 3D BD players wll also support 1080 60p 2D video. However, it's hard to find any confirmations, real spec lists, or firmware links to learn whether this is really the case. People are also apt to confuse 60p with 24p, or assume that the inquirer wants to know whether a player supports "progressive," which traditionally meant 24p only. Typographical confusion between 60i and 60p occurs all the time too. Or someone will have a 60hz display and think that means one sees 60p video. In other words, this is a topic that goes in circles. My search for an answer leads, often enough, to unanswered queries place months ago, or as far back as early 2010 when the Panny TM700 introduced 1080 60p video.

Thanks for any clear guidance.

AFAIK, all Sony 2011 *80 series support AVCHD 2.0 and 1080/60p files with a FW upgrade. I know of NO other players that support AVCHD 2.0. I have a Sony BDP-S580 and have successfully created AVCHD 2.0 1080/60p BD's from Panasonic TM900 1080/60p 28Mbps camcorder files that play on the S580. I assume all their newly announced *90 series BD players will support AVCHD 2.0 as well.

Sony and Panasonic developed the new AVCHD 2.0 spec, so I'm hoping Panasonic's new players coming out this year will support it as well. None of last years Panasonic models support AVCHD 2.0. I have not been able to find any detailed specs on the new Panny BD players that suggest support for AVCHD 2.0 (no complete specs available yet), but would be shocked if they didn't support it.

This probably comes a little too late for you, but for the information of other folks reading this thread: I've just purchased a Panasonic BDT-220 player - it has SD card and USB slots on the front panel.

It plays 1080p60 from an SD card as long as the files are in AVCHD format (i.e., have the requisite folder structure and metadata files). It won't play individual .MTS files copied to the card.

It plays 1080p60 from an MTS file of arbitrary name in any folder of a USB flash drive.

I don't have any disc-based 1080p60 content to try, but I'd be surprised if it didn't play as long as it followed the AVCHD 2.0 spec.

Why these manufacturers distinguish media type when deciding which formats to play is beyond me...

No firmware updates were required for 1080p60 support. The unit is labelled as being manufactured in June 2012.

Greetings Sean.

Would you be kind enough to test if the Panasonic BDT-220 will handle a 1080/60p Blu-ray?

Here is an ISO image that can be burned to a BD-R or DVD-R, courtesy of Ungermann.

The first four clips play without any issues. The last clip (which shows a date/time stamp) plays, but with excessive stuttering. My receiver shows the HDMI signal coming out of the player is either dropping out or it's having to re-synch to it at irregular intervals of approximately every second or so.

Update: I copied the last clip to a USB flash drive it played without any problems, so I'm pretty sure that Ungermann's comment about the DVD not having a high enough data rate is the culprit and not any limitation in the video pipeline of the player. I'd be very surprised if there was an issue playing the clip from an actual BluRay disc (but without a BluRay burner I have no way to test it).

Greetings Sean.

Thank you very much for the test and best regards.

What is the right set of folders to get most BD players compatible AVCHD on DVD-R media, using multiAVCHD?

Can some one please to confirm/clarify:
1. The two folders BDMV and AVCHDTN created by multiAVCHD need to be placed in DVD-R Root directory?
This is actually done on ISO file to test mentioned in this tread.
2. "AVCHD Strict" in two places of multiAVCHD need to be checked in order to create "AVCHD on DVD-R" playabale on most BD players.
3. The other methode I have seen is placing BDMV and Certificate or only BDMV folder (with more than four folders inside) in the Root directory are not correct or will not play on some AVCHD rated BD players?

Can you share your experience.
