[Solved] Sound/Video sync problem rendering big file

[Russell E]

Hi,

I'm having problems trying to archive my old VHS cassettes to DVD using VideoStudio SE 10.0. Short films are no problem, I can just burn the captured MPEG -2 file direct to DVD and it plays just fine. However my DVD player fails on MPEG files over about 1.5 GB.

O.K. for a long (2 h 30 min) I capture using EZCap116 with bit rate set down to 4000 kB/s. This produces an MPEG -2 file which plays fine on the computer. If I render it to DVD format and burn to disk I find that the sync deteriorates as the video plays and is several seconds out by the end of the film.

If I do the rendering and burning with AnyVideoConverter the result is fine so either I need to change some settings in VideoStudio or there is a problem with the software.

Any ideas? I would like to avoid having to swap between applications.

Thanks.

Russell.

Hi Russell

The video file created by EZcap is a compliant Mpeg2 suitable for burning a DVD.
Right click the file in the timeline and select properties, what are they?
At 2hr 30min it may be to large to fit to disc, if the captured file is greater than 4.3 Gb then reduce the ezcap capture bit rate below 4000kbps. (a standard DVD will only hold 4.3Gb)

After editing Share Create Video File—Same as First Clip should produce a file using the original files properties.
From the save as window choose Options, deselect Smart Render.
-------------------------
Ok if the file is larger than 4.3 Gb, use Make Movie Templates Manager-Add function to create a template to the files properties, now edit the template reducing the bitrate to 3500kbps.
Share Create Video File, use your template now available adjacent to the Custom option.
The new video file should be below 4.3Gb
Play the file to check quality and audio sync’

Now start a new project, nothing in the timeline Share Create Disc, Add Video File, choose the new video file.

On the final window choose to Create DVD Folders.
The completed files are the same as the DVD content, play these on the PC to check quality and audio sync.
If Ok burn a DVD

Thanks for your quick reply Trevor.

The MPEG file size is 3.6 GB (3,895,410,688) so it burns to a disk OK as a file. The disk then plays OK with good sync on both my computers in both Windows and Linux but stops about halfway through when played on my DVD player (a Toshiba model a few weeks old). I suspect it may be normal for a DVD player to object to large single video files hence the splitting of the file into 1 GB chunks when rendering.

I first started with a bit rate of 4500 but the file came out at 4.3 GB (4,633,403,392) this is just small enough to burn to a DVD-R but when rendered to DVD it grows a bit and is too big. 4000 b/s is OK in that respect.

"After editing Share Create Video File—Same as First Clip should produce a file using the original files properties." I have tried that and the created file plays OK on the computer.

I will try your other suggestions and come back.

Thanks again.
Russell.

Just a bit more information: I have had another look at the rendered DVD I burned and there are four VOB files in addition to the menu. If I play them separately on the computer with (VLC media player) I find that the first file is in sync all the way through but the others have the sound delayed more with each file, the last one having a 4 sec delay.

Regards,
Russell.

The dvd standard is for vob files of 1gb, this is just how the guy who invented it, made it

This says you have no problems playing the dvd on your computer, only on the dvd player. This means your dvd has been made properly, you just have a compatibility problem with your dvd player. How does it play on other peoples dvd players?

But then you say.....

So, does this post mean the dvd doesn't play ok on your computer when you select the individual vobs, but it does play ok in vlc if you press play and let it play continually?????

To be honest, in all my years of making thousands of dvds, I have never come across that problem?

How does it play in WMP or other dvd playing software?

[Russell E]

Thanks for your input Graham.

Yes, I am aware of that, but I was talking here of a MPEG file recorded on a data DVD disk. I can record up to 4.38 GB MPEG file and play it back OK on both Windows and Linux PCs. Both DVD players I've tried will play part of the file and then stop. Is there a spec for the maximum size MPEG or AVI file for a domestic DVD player?

Sorry if I wasn't clear but I was saying that the large MPEG file recorded on a DVD disk plays OK on the computer but won't play all the way through on the two DVD players I've tried.

No. The rendered and burned DVD has up to 4 sec error both on the computer and on the DVD player. I was pointing out that the problem gets progressively worse for each VOB file.

The problem isn't one of capturing or editing but it occurs during rendering/burning.

Hi

Russell, you have rendered your project to a single Mpeg2 file that is under 4.3 Gb, so it will fit to disc without being rendered again.
Double check this file, play it to make sure it is in audio sync’

New Project
Share Create Disc – add video file
From the last window choose to create a DVD Folder, deselect Create Disc.

When you press the Burn button the process should start with Create Menu.
The Mpeg2 being used without further conversions.

If you see Create Title then the video file is being rendered again. Not what you want.

The completed file will be saved to a Video_TS folder, this folder is exactly the same as the DVD disc files.
Play the Video_TS using VLC Player to check the quality and audio sync.

[Russell E]

OK. I've just finished running a series of tests and it looks as if this is a definite bug in the software but thanks to Trevor I have a workround:

Test 1:
Capture 2.5 hr video at 4000 B/s
Click on Edit tab
Drag file to Timeline and trim both ends
Click on Share tab
Select Create Disk > Next
Select a menu > Next > Create DVD Folders > Burn
RESULT: The .VOB files have increasing audio delay up to about 4 sec.

Test 2:
Restart VideoStudio
File > New Project (nothing in timeline)
Share > Create Disk > Add Video File > select the captured file
Trim both ends > Next
Select and edit menu > Next
Create DVD Folders > Burn
RESULT: The VOB files all play OK.

Test 3:
As test 2 but Create to Disk
RESULT: DVD that plays OK on both DVD players and Windows and Linux computers.

So, if I go from the Edit tab to the Share tab the rendering somehow gets borked. Surely the way I have done things in Test 1 should be OK? I have tried to find an update but the update server doesn't seem to be working, at least my installation can't contact it.

Thanks for your help guys.

There have always been problems with going direct to burn with VS.
The general advice here is always to create a video file and use this.

I use other editing software ona regualr basis adn these also suffer similar problems, no idea why

Sorry, I didn't realise you were also creating a data dvd, what make/model of dvd player do you have that plays these discs? I've only seen ones that play xvid.avi / divx.avi or jpegs.

Hi

First of all, I and many users always use the Test 2 approach.
View my “quick guides for Mpegs” link below

Using Test 1 approach means you are adding a project file (VSP) to the burner module.
View the “I” adjacent to the clip for media clip information, notice it’s a VSP not an Mpeg2

The project has to be converted/rendered to a Mpeg2 file which is used to burn the disc, this process can be seen after hitting the Burn button, the progress bar showing Create Title.
The conversion settings used to do this can be seen by hitting the options icon lower left.
These settings need to be the same as your video files properties.

Test 1 approach works perfectly ok for most users. There are no bug in the software, the probable cause are converting the video twice when once will do, incorrect settings, or corrupt video file, to mention a few.
-------------------------------
You have already created a compliant Mpeg2 file that does not require re-coding

Use Test 2 approach.

Oh … and glad you have managed to create a good disc

[Russell E]

Sorry, I didn't realise you were also creating a data dvd, what make/model of dvd player do you have that plays these discs? I've only seen ones that play xvid.avi / divx.avi or jpegs.

I have Toshiba SD3005KE player and Digitek DVR-80PH player recorder, both French versions. They both play MPEG files (but not big ones!)

Part of your problem may be that you are trying to burn a 2.5 hour video on a 4.7GB DVD. The video requires a lot of compression to fit and that is what maybe causing your sync problems.

I have never seen or heard of any DVD player that is able to play mpg files burned as data

[teknisyan]

our Sony DVD player can play video files or video files burned as data on a dvd. The problem is that it will not play all video files, since it may support only a selected sets of video files, so you may want to consult with your DVD Support on what are the supported video files.

[skier-hughes]

According to Digitech this model only pays divx.avi files, it doesn't list mpeg. I can't find any record of the toshiba model on toshiba's sites in France, Europe or worldwide, but the 3010 is again the same, mp3 and jpeg support and a proposal for divx.avi no mpeg support.

It's most likely notworking because it wasn't designed to do what you are asking it to do

Capturing with a data rate of 4000 kB/s from a 2.5 hour video gives me a file that will easily fit on the CD but thanks for your input.

That's interesting because the Toshiba certainly does work on smaller files. I may be mistaken about the Digitek. I've tried so many combinations I may be getting confused. (It's my age )

That's true.
