Pleyback problems with AVCHD and Biu-ray disks

langford wrote on 4/30/2016, 11:01 AM

I have been producing DVD films for more than 10 years with a good level of success. I have just moved up from filming in SD to full HD using a Panasonic HC-920 camera, and I edit and burn with MEP 2013plus,in Windows 7 Professional. Using this new format I have just completed a wedding video filmed at 1080p and presented on DVD.The DVD format was selected in order to give max.play back use.For my own use I also produced a AVCHD and a Blu-ray disk.

The DVD plays with no problems on PC/DVD player/Blu-ray player, but the AVCHD and Blu-ray versions both have playback problems.AVCHD disk plays on PC and Blu-ray player but with no menu, and has a slight problem on play back in moving scenes. The movement of people is a little unnatural.Blu-ray disk plays for only a few seconds on PC or Blu-ray player and then returns to rhe title, the disk appears to be fully "burnt".Again there is no menu.

Looking at the file structure of these disks using PowerDVD 10,I can open the BDMV folder. All folders are empty except stream which contains 3 files.These are 00000m2ts,mpeg2 transport stream-this is the 90 min film. - 00001m2ts,this the film title. - 00002m2ts, this is the menu.

Opening files 00001 and 00002 on a PC gives no images, but 00000 plays the disk less title and menu.The BDMV folder is the same on all dsks.

Encoder settings used - DVD default setting. AVCHD - H264 1920x1080i 25 fps 18384 kbit/sec.Blu-ray - same but 18000 kbit/sec smart render on.

Hope I have provided sufficient infotmation.

Help would be apprecated.

. . . . Opening files 00001 and 00002 on a PC gives no images, but 00000 plays the disk less title and menu. . . . .

The behaviour you are seeing on the PC is correct when the menus for the disc are static ie eg no video background or animation - they will not play individually.

To play a BD disc correctly on aPC with the main and chapter menus you need BDplayer software installed on your PC - I use Nero BD Player which is part of the Nero suite of software.

Which menu template did you use for the BD and AVCHD disc?

. . . . 00001m2ts,this the film title. - 00002m2ts, this is the menu. . . . .

Do you have an intro video that appears before the main menu or main menu and chapter menu?

. . . . both have playback problems.AVCHD disk plays on PC and Blu-ray player but with no menu, and has a slight problem on play back in moving scenes. The movement of people is a little unnatural.Blu-ray disk plays for only a few seconds on PC or Blu-ray player and then returns to rhe title, the disk appears to be fully "burnt".Again there is no menu. . . . .

What brand and type of discs did you use?

video filmed at 1080p

This camera films in 1080 50p or 25fps interlaced. Which did you record in as there can be some jerkiness when converting via MEP to the 25fps Interlaced Blu ray standard? Did you burn the DVD as 25 Progressive or Interlaced?

AVCHD - H264 1920x1080i 25 fps 18384 kbit/sec.Blu-ray - same but 18000 kbit/sec smart render on.

If your original footage was 1080P then Smart Render would have been ineffective disabled if you were burning to an interlaced or different format like MPEG2. Or did you take the rendered 1080 25i file from the AVCHD 1080 25i render and use this in a new project for the (MPEG2?) Bluray burn? In any case I would not use smart render where you seem to be having problems.

I am wondering why you chose to use a different (MPEG2?) format for the Bluray as most all BR players will play the AVCHD Bluray format and the quality would be much better, at 18000 or so Kilobits/sec, than an MPEG2 HD format at the same bitrate?

Play back problems with AVCHD and Blu-ray disks.

Scenestealer- Hi Peter.

Thank you for your reply to my questions of 30 April 16

Film was recorded in 1080/50p this is the highest picture qulaity available on HC- X920 camera.

Encoder settings used - Blu-ray burn- H246 and 1080i 25fps were self selected by the prog.There appeared to be no other options with H246. I have now found there is a 50fps option if MEPEG 2 is selected but this results in a Invalid parameters warning.

Also in advanced MPEG settings - General Settings - Progressive can be selected and this option appears to be accepted by the prog.

Regarding the files used to produce the AVCHD and Blu -ray disks, the data was the same as for the DVD, MPV files produced during the edit process and not rendered.

The problem of unnatural movement on play back is only apparent on the AVCHD disk,the same data was used for the Blu-ray disk and this has no movement problems. The problem of no menu is common to both disks.

regards

Roy

Play back problems with AVCHD and Blu-ray disks

Johnbaker Hi John.

Thank you for your reply to my questions of 30 April 06.

I am surprised that the prog that created the disk cannot play it back without additional software. There seems to be no reference to this in MEP 13plus user manual ot Magix Academy texbook.

The menu templates were static, taken from MEP template menu. There is no intro video at the start of the film.

Disks used - DVD Verbatim DVD-R printable. AVCHD and Blu-ray Verbatim BD-RE printable. Rewritable disks used as I could not be sure of the reaults as this was my first experience with full HD.I need to resolve how to produce a fully functioning Blu-ray disk that will play without problems on a Blu-ray player.

regards

Roy.

If you click the down arrow at the top of the "DVD (30mins) > AVCHD Burn > Encoder settings" window you can select 1920x1080p (50-mode) which will allow you to burn an AVCHD 1080 50P DVD disc that will play on a computer at least, in high def, although I have not tried this in a Bluray player. If the Bluray player will play it, it might also depend on your TV's ability to display 50p as well.

You are correct with the MPEG2 Bluray standard - it only allows 1080 25i or 720 50p.

Scenestealer Hi Peter

Thank you for your response of 5 May 16.

Your suggestion to burn AVCHD disk at 1080p 50fps may well result in a smoother play back,it is still of concern

to me that Blu-ray version did not have this fault when burned at 1080i 25fps.

My biggest concern relates to the menu problems with both the AVCHD and the Blu-ray disks and the very short

play back time of the Blu-ray disk, as set out in my questions of 30 April 16.

Regards Roy.
