Interference around straight lines and fine objects

[654321]

I am using VS7 SP!. I made an mp4 of a video and it is perfect. Then I burned a DVD (not from the mp4 but the original video) and there are interference patterns around straight lines or fine objects. I am using a DVD +R for the first time. I usually use a DVD -R and never had that problem. Is there something I am missing that has to be done differently when using a DVD +R?
Thanks.

What are the properties of the original mp4? I suspect it will probably be 1920 x 1080, and depending where you are in the world, either 25/50 fps (PAL) or 29.97/60 fps (NTSC). More importantly, if you right click one of the mp4 clips in the VS timeline and select Properties, does it say Upper Field First anywhere? If not, you will have progressive video, which is equivalent to Frame Based in standard definition video. I suspect this will be the case...

Now when making the DVD, did you simply accept the default settings offered by VS? If so, the DVD template has Upper Field First set by default, and this is probably what is causing the interference you describe (commonly known as "jaggies"). So you would need to choose Custom and make a DVD-compatible mpeg-2, but choosing Frame Based as the Field Order instead of the default Upper Field First. When you make that mpeg-2, you can then play it on a software player to see if the jaggies are still there. If not, you can then open the burning module, insert that new mpeg-2 and burn it to DVD. FWIW, I don't think your using a DVD +R has anything to do with your problem.

You are right about RW+R was not the zaggies are still there with a DVD-R. Puzzling as I never experienced before.
Just to make sure that I explained myself properly, the MP4 made from the timeline in VS7 is fine. Burning from the timeline from VS7 to a DVD is where the problem occurs.
I set up a new custom template as you said.
Under the General tab I set the following:
Encoder driver: Ulead MPEG. Now Encoder
Data track: Audio and Video
Frame Rate: 29.97 frames/second
Frame Type: Frame-based
Frame Size: Standard 720x480
Display Aspect Ratio: 16:9

Under the compression tab:
Media type: NTSCDVD
Quality: 100
Video format: MPEG-2 No boxes checked
Video Data Rate: Constant 6000kbps
Audio format: Dolby digital
Audio type 2/0(L,R)
Audio Frequency 48000 Hz
Audio bit rate 256 kbps

The properties of the MP4 in the timeline are:
Video type: H.264 High Profile Video
Attributes: 24 bits, 1920x1080, 16:9
Frame Rate 23.976 frames /sec
Data rate: 34999 Kbps

Setting the frame type to frame-based did not help with zaggies very much and introduced other artifacts in horizontal lines.

Could you make some other suggestions please? Thanks.

In your first post you stated that you created the DVD from the original video and not from the mp4 video you created. So what are the properties of the original video you used in making the DVD?

Hi

A little confused here…
What are the properties of the original video files, before you created the mp4.
The mp4 seems to be using 23.97 fps, when you burn the disc this is being converted to 29.97fps, effectively duplicating 6 frames per second? That may impact on your quality.

So again what are the properties of the original video files?

As the new mp4 video file is “perfect”, why did you use the originals for burning to disc.
Try converting the perfect mp4 to Mpeg2

Rather than burning a disc (Share Disc) create the video file first

Import the good video file to the timeline
Share – Mpeg2
The template you choose may depend on the properties of the original video files.
Or use the template you create earlier, if that is suitable.

The render process will create a compliant video file (mpeg2) suitable to burn a disc.
Play that file to check quality.

My apologies for not explaining things clearly. I have everything in the timeline and from there I made an mp4.That did not have any jaggies or artifacts at all.

Then I burned a DVD using the using the same timeline and there came the jaggies.

Here are the properties of the original video before insertion into VS7.
Frame Width: 1920
Frame Height: 1080
Data rate: 34981kbps
Total bitrate: 35109kbps
Frame rate: 23 frames /second

I did the "share mpeg 2" then inserted that into VS7 and burned a DVD and that did improve the quality. But there still jaggies albeit not as visible.

How long in time is your project? If it is 60 minutes or less you should be using a bit rate of around 8000 instead of the 6000 you posted.
Of course "compressing" the 1920x1080 video to the DVDs 720x480 will result in quality loss as will the increase in fps from 24 to 30 as it introduces extra frames

[654321]

The project is only 12 minutes so I increased the bit rate to 8000. How do you change the frame size to 1980x1080? The standard frame size dialog box is set at 720 x 480, and the user defined box is grayed out.

Thanks.

The maximum "frame size" of a standard DVD is 720x480 for NTSC (or 720x576 for PAL) and cannot be changed.

654321,
Here's two methods that work for me. On my system any DVD I make from a project turns out badly.
1. Since you can make a good mp4, you should be able to make an mpg2(as has been already suggested) with similar settings as the mp4. View the mpg2 with VLC player to verify it is good. Open a blank project in VS and go right to the share stage. Import your mpg2 and go on to burn the DVD. This breaks up VS's mpg2 conversion and burn stage and sometimes makes a good DVD. But not always.

2. Instead of making a DVD from the project, make an ISO. View it with VLC media player to make sure it works. This you can burn to disk with most disk burning software or even VS. Go to TOOLS and there is an option to burn to disk.

I have also found that I often need to add a sharpen filter to DV tape AVIs to make them as clear as the original.

Hi

As your project is only short, have you considered burning a avchd hybrid disc.
That uses the Standard Definition 4.3 Gb disc but uses Avchd files.
To play the hybrid disc you will need a Bluray Player, but you can complete the process to play the files on the pc.

If you convert your project to Share AVC/h.264, you may have to create a new template to use 23.97 fps (use the + symbol.
These are for Pal—you will use Ntsc?

MPEG Transport-Stream Files
24 bits, 1920 x 1080, 23.976 fps
Frame-based
(HDMV-PAL), 16:9
H.264 Video
Video data rate: Variable (Max. 18000 kbps)
Audio data rate: 384 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)

Play that to check quality
Start a new project – Share Disc – Avchd – add Media files – add Video
Create a menu
On the last page choose to Create a AVCHD Folder, that will save the files to your hard drive.
Locate the Stream folder to play the 00000.m2ts file

What is the quality of that file.?

Other Options
Do you really need a DVD disc, you could save the HD files to USB memory stick and playback on your TV/DVD/DB Player, you would have to find a suitable HD format that your players supports, Mpeg2 , MTS, they may support Mp4?

Thanks for all the help. I had the best results in my case setting the bit rate to 8000 and making a MPEG-2 and then burning that to disk. I needed several DVD's to distribute a video of Nordic Skiing event for a Parkinson's fundraiser. Skis and ski poles especially were producing jaggies as were some snow covered Aspen trees. I filmed the event using a Cannon camera and a GoPro Hero 3+ Black mounted on drone. Kind of off subject, but does anyone have any recommended settings using a GoPro that work best for making DVD's?


Thank you again!

[Ken Berry]

Unfortunately not. I have a Hero 3 Black, but have never made a DVD from any of its footage. I only produce high resolution video from it, either in its original mp4, or else AVCHD.

However, there is a relatively small limit on what you can do in making a DVD out of the original mp4 footage. By international standard, it has to be mpeg-2 with a maximum frame size of 720 x 480 (NTSC) or 720 x 576 (PAL). Audio can be Dolby, which gives the smallest footprint, and standard (L)PCM. The maximum bitrate of both video and audio combined cannot exceed 10,000 kbps but most DVD players have difficulty with home-made DVDs using a bitrate higher than 8000 kbps. However, that still gives excellent quality (depending, of course, on how good the original footage is!). It also allows about 70 minutes of video to be burned to a single layer disc using dolby audio.

In your case, the most important thing is the Field Order, as you have already found. If you use the GoPro filming fully progressive footage (30p or 60p), then you should use Frame Based in making your DVD-compatible mpeg-2. Otherwise, use Upper Field First, since that is what the GoPro uses for its interlaced footage.

But IMHO it is important first to make a DVD-compatible mpeg-2 with those properties, test it in a software player, and if satisfied, then burn it to DVD. Many users find they get problems if they take what they think is a shortcut and jump straight from the project to burning a disc. And in the VS burning module, once you have your compatible mpeg-2, make sure, in the Options cogwheel icon in the bottom left of the burning screen, that you tick the box beside "Do not convert compliant MPEG files". If not ticked, your video will be converted again, using the properties shown in that same Options icon up at the top... and that by default is set to use Upper Field First. This will again most likely produce jaggies if your mpeg-2 is in fact Frame Based.

If you need to make several identical DVDs, it is recommended to first burn to an iso image file or a Video_TS folder set. You can then burn these to multiple DVDs without having to do any re-rendering

If you didn't have interference problems in the past, were the DVD's originating from a 1920x1080 source?
