Moviefactory 7: Blu Ray audio/video synch issue

[Nalepa]

I have been a Ulead moviefactory user for over tens years upgrading from version 2,3,4,5,6 and now 7.
I produce and burn many DVDs. In the early years I always had audio/video synch issues.
I resolved this by not using any MF5 or 6 editing options like trim tool, add text, add audio etc, that would modify the original video and instead did all my video rendering/editing work in VideoStudio 11.
Hence, I use VS11 to do all my editing and MF to simply author a DVD. This has work very well for many years now with no stablity/quality issues.

So I was surprised that this issue is still real in MF7. I upgraded from MF6 because the HD options are terrible and very basic.

This is what happens:
1) I use VS11 to capture the video file from my Canon HV30.
2) The raw file is MPEG4 and at 25,000 BPS
3) I use VS11 to trim, edit, add text, music etc to this file.
4) I then create an output video file using "use the same settings as per the first video clip". Hence the properties of my created video clip is the same as the original.
5) I then use MF7 to load these files (five of them) to make a Blu Ray DVD. Each video is 20 to 30mins.
6) I used the trim option to cut out sections of video in order to get the total project below 25GByte.
7) I then output the project to a DVD folder
After successfully burning a Blue Ray DVD, the four videos I added would have the audio drift in and out of synch but always perfect at the start . The last video would play perfectly, yet it is the same video output created in VS11 with the same amount of trimming?

The MF7 settings have "do not modify compliant MPEG files" and so making a Blu Ray DVD is fast, 30 minutes.

Hence, do I need to go back to my old ways and do everything in VS11 and just use MF7 to add videos without any modification in order to create a DVD?

Any help would be appreciated.

Can we first clear up an issue of terminology? You use the term 'Blu-Ray DVD' several times in your question. Did you mean an actual Blu-Ray disc, using a Blu-Ray burner and Blu-Ray blank disc? Or did you mean a Blu-Ray formatted video burned in a Blu-Ray structure but on a DVD blank disc? The latter is known as an AVCHD or hybrid disc. A video DVD is a standard definition disc burning using a totally different structure to a Blu-Ray disc.

Hi Ken, Sorry my terminolgy is not up to speed.

When selecting what type of project on the opening page of MF7. I select Blu Ray.
This give me the unique menus and titles specific for producing a Blu Ray Project
I output the MF7 project to a folder on my computer first. MF7 creates all the sub folders and Blu Ray files.
Once complete, I then check this folder to ensure that it is less than 25GBytes.
I have a Blu Ray Disc Burner (25GByte only), drive F:
I use the Corel Burn option, select Blu Ray and select this folder to burn the project onto a blank disc.
All works very wells and the disc works in a blu ray player.
It is when I insert this disc into my TV Blu Ray player that I notice that the audio is out of synch with the video. This get worst towards the end of the video.
Last night I checked what the properties are of the video files imported from my camera.
They are:

MPEG-2
Upper field first
24Bits, 1440x1080 16:9
25 FPS
25,000 kBPS
Audio MPEG, 48kHz, 16 bit 384kbps

I use Video Studio 11 to edit , clip, trim and add text and music to this video. Then output to a file keeping the video property settings.
I have reviewed this final video file and find that the audio and video are in synch.
So it must be something in MF7 that is causing my issue.
I need to buy a Blu Ray Player for my PC in order to check the MF7 created BR folders. The one I bought from Corel only allows Blu Ray video to be played from a Disc in a Blu Ray PC disc drive and not from a PC Folder?

Is there an issue with the video properties from my Canon HV30 video recorder. I do not wish to convert compliant MPEG files as experience has shown that it takes an enourmous amount of time and the quality suffers.

So I think I have two options to explore.
1) Redo the video files in VS11 and complete the trimming work so that the video is not clipped or trimmed in MF7
2) Change the audio settings and force MF7 to lay the audio correctly against the video.

Any other suggestions?

thanks Peter

Not sure I understand. Are we talking about two different Blu-Ray players here: the first one where the disc works; and the second one being your TV Blu-Ray player?

If there are indeed two players and the disc works well in one of them but not the other, then I would have to say something is wrong with the second player, not the program.

Sorry,
I meant to say that the burnt/created disc works well on all machines except that the audio is out of sync.
So making a Blu ray disc has no problems.The burning program works well.
The issue is that the video file created by MF7 does not synch the audio to the video.

Would another idea be to create smaller video files in VS11, lets say 5 minutes each and then group them in MF7. Would this work given that the drift between audio and video is reset every 5 minutes?

It has been a long time since I used VS 11+ -- and I can't remember if it offered the output option of Blu-Ray i.e. Share > Create Video File > Blu-Ray. If it did, then you would be producing a video from your project which is already Blu-Ray compatible, and which, in MF 7, would not need to be rendered again. This should mean that the out of sync issue should not aris.

Hi Barry,
Found the root cause.
Converting my original video to Blu Ray Format in VS11 causes synch issues.
Converting my oringal video to Blu Ray in MF7 causes synch issues.
It appears both methods have problems with converting my original MPEG Audio to either LPCM or Dolby Digital and layering it correctly against the video track.

VS11 does have two Blu ray output options but it appears they may be outdated or not compatible with my original video format. They are
BD-Standard Upper Field First , LPCM but at max resolution.
BD-J, Lower Field First, Dolbly Digitial.
Selecting 1440 forces the field to change to LLF.

If you do not match the upper or lower field it takes a long time to convert since the video odd and even lines are swapped over. This caused a major out of sync issue.
Changing from 1440x1080 to 1920x1080 with the VS11 BD-standard option, took a long time and reduced video quality but resolved the synch issue.

So I have downloaded the latest VideoStudio Pro (a shame that I do not get an upgrade price since the look, feel and features are similar to VS11) becuase it has many more Blu Ray options around 1440x1080 that is UFF.
The result is no more synch issues after authoriing in MF7.

Hence the solution is to use VS pro to convert original Video to Blu Ray:
Original
PAL HD DVD
MPEG-2
UFF
24 Bit 1440x1080 16:9
25 fps
25,000 kbps
MPEG Audio 48khz 384kbps

Blu Ray Output
Blu Ray (1440x1080)
MPEG-2 Transport System
UFF
24 Bit 1440x1080 16:9
25 fps
25,000 kbps variable
Dolby Digital, 48khz, 384kbps

The conversion is very fast and in perfect sync and that tells me the video quality is not compromised.
thanks
