Audio Glitches When Burning Dvd-video And Ac3

[razorray]

I've recently upgraded to EMC10. When I use MyDVD Express to burn from a VIDEO_TS folder, the audio has glitches (that is garbled or silent spots of a few seconds every minute or so.) This is only apparent when played on my Samsung DVD V5500, not when played on my PC (PowerDVD for one).

 

The input video has the following properties:

File Name: E:\VIDEO_TS\VTS_01_1.VOB

File Size: 1073725440 ( 1.00 GB )

Program Duration: 00:22:49.20

File Type: PS - MPEG2

Encoding: MPEG 2

Video stream Id: xE0

Encoding Dimensions: 352 x 480

Display Size: 352 x 480

Aspect Ratio: 16/9

Frame Rate: 29.97 FPS

Bit Rate: 4.600 Mbps

VBV_Buffer: 224 KB

Profile: Main/Main

Progressive: Prog or Int

Chroma: 4:2:0

Audio Format: 2

Audio Stream Id: LPCM:0 (xA0)

Audio Bit Rate: 16 bits

Audio Sampling Rate: 48000 Hz

 

The only way I can burn a DVD that will play OK (but at reduced video quality), is to first create an MPG file from the DVD-Video, and then input that into MyDVD and specify 352x480 5Mb/s + LPCM. The reduced video quality is the only way to now fit it on the 4.7gb DVD.

 

Any thoughts or suggestions would be appreciated. My Samsung player does support AC3 sound though I suspect at a rudimentary level.

 

 

My Bad, the initial post of video properties is incorrect. Here are the correct input video properties:

File Name: G:\movin\Foyle's War\Foyle's War 41\video_ts\VTS_07_1.VLST

File Size: 3859482624 ( 3.59 GB )

Program Duration: 01:33:44.13

File Type: PS - MPEG2

Encoding: MPEG 2

Video stream Id: xE0

Encoding Dimensions: 720 x 576

Display Size: 720 x 576

Aspect Ratio: 16/9

Frame Rate: 25.00 FPS

Bit Rate: 6.000 Mbps

VBV_Buffer: 224 KB

Profile: Main/Main

Progressive: Prog or Int

Chroma: 4:2:0

Audio Format: 2.0

Audio Stream Id: AC3: 0 (x80)

Audio Bit Rate: 192 Kbps

Audio Sampling Rate: 48000 Hz

The video is only 22 min. That should fit easily at the highest quality settings on a 4.7 disc even with LPCM audio.

Well, I tried VideoWave and then MyDVD with the same results. That is, the audio has glitches (that is garbled or silent spots of a few seconds every 40 seconds or so.) This is only apparent when played on my Samsung DVD V5500, not when played on my PC.

 

Properties of input video:

Type: MPEG-2

Data Rate: 8 Kbps

Length: 01:33:47.23

Video Stream:

Frame Size: 720x576

Frame Rate: 25 fps

Compression: Roxio MPEG2 Video Decoder

Audio Stream:

Format: 48000 Hz, Surround sound

Compression: Sonic Cinemaster Audio Decode 4.3

 

Output As:

Generic MPEG-2, good quality

Video: Roxio MPEG-2 Video Encoder, 720x480, 29.97 fps, 8 Mbs

Audio: Roxio MPEG1 Audio Encoder, stereo, 44.10kHz, 16bit, 320 kbs

File created: FW 42.mpg is 5.5gb

MyDVD to burn with Fit-to-disc. Result when played on Samsung DVD player = video plays fine but with audio glitches.

 

Did another "Output As" with a new profile for Video quality:

Video: Roxio MPEG-2 Video Encoder, 720x480, 29.97 fps, 6 Mbs interlaced

Audio: Dolby Digital AC3, stereo, 48kHz, 16bit, 192 kbs

Normalize audio

File created: FW 42 b.mpg is 4.1 gb

MyDVD to burn with Fit-to-disc. Result when played on Samsung DVD player =video plays fine but with audio glitches.

 

One thing to mention is that I realize this Samsung DVD player is a bottom end device, it does play store bought DVDs just fine.

 

Any more things to try ?

TIA

Usually bottom end machines play better than top end (strange but true)

 

However, what brand media are you using?

[razorray]

I am using Verbatim DVD+RW and DVD+R.

[firenhancer]

Try burning at slower speeds. Though Verbatim works for me all the time, if you can manage a different brand perhaps.

[Jim_Hardin]

Dash is dash. Some Players just don't do will with 'plus' media.

 

Yes you can change the Booktype of 'plus' but first you have to have a burner that supports it and then you need a software program, usually from the burner manufacture, to change the burners firmware… and if the Player cannot handle AC3 sound, all this is wasted effort.

 

Testing with 'dash' is quick and easy.

 

[Jim_Hardin]

You did not say how it plays on your PC…

[razorray]

Please ignore the first list of the input video specifications and see a second list. That is the correct data. The video is 90 minutes long.

[razorray]

The videos I burn all play fine on my PC.

[Jim_Hardin]

The videos I burn all play fine on my PC.

Then there is nothing wrong with the disc and nothing can fix what isn't broken…

 

One thing you could try is using 'dash' media. Some Players will only work well with a specific type.

 

If that works, then we will want to know what Booktype you are burning the 'plus' media to.

 

[Jim_Hardin]

Well that is about as clear as mud!!!

 

Get yourself a disc or 2 of DVD RW media. (good stuff like Verbatim)

 

Forget the MyDVD Express program and never use it again!

 

Import the video into VideoWave and look at its' Properties. If the raw source is 352 X 480 then that is as good as it will ever be! You cannot gain quality, too much is already missing.

 

Try Output As and pick an mpeg2 format that matches the original.

 

Open MyDVD and add the file you just made and burn it to the RW media you got to play with. Keep in mind that a 4.7gb DVD can only hold about 1 hour of Video at best quality...

 

Results when played on your PC? How about a Player?

It could be a perfectly good disc, and a 'rudimentary' AC3 player, as Razorray mentioned. If the firmware on the player struggles with AC3 audio that could well produce the effect he complains of.

If that works, then we will want to know what Booktype you are burning the 'plus' media to.

 

Jim, did you mean to say he should use dash media - in which case it will come out as DVD-R with no option for him to change?

Or did you mean to say he should use plus media and change the booktype to something else?

Your suggestion seems confusing. Can you clarify it please?

Brendon

Per your updated post, that file should still fit on 4.7 disc just fine with NO re-rendering (expect the places you edit). As Jim has suggested, I agree that MyDVD should be used. Perhaps your issue is with MyDVD Express.

[razorray]

I thank everyone for their assistance.

 

I finally bought another DVD player a JVC XV N670B and it plays the DVDs fine. It also plays DIVX DVDs which is very nice.

 

I have also discovered that I still get audio glitches in the form of excessive background static if I burn DVDs while doing anything else on my PC. This is amazing to me since I have a fairly powerful dual CPU system. But I have verified this three times now. Apparantly buffer overrun protection is not enough to guarantee a clean encoding and burn ?

DVD players general take a hissy fit if BURP has been invoked during the creation

 

Having a dual core doesn't help a lot really. It's always as well to start a render and go off and watch some TV, cut the grass or anything else and let the box carry on with the black arts and convert that file to DVD
