What kind of format is a dvd

The MPEG-1 video compression method takes advantage of the fact that often, many frames in a row are very similar showing the same background and objects, for instance, with only an actor's face and hands moving. For each frame, it is only necessary to record how it differs from the previous frame , saving storage space.

In addition, the audio encoding uses something called psychoacoustics—compression removes the high and low frequencies a normal human ear cannot hear. Video and audio are encoded using MPEG VCD is the most universally compatible format for wide video distribution. The video quality is better than most other formats and is adequate for typical home viewing. If recorded using the highest quality, it is virtually DVD quality.

There are video broadcasting standards, also called picture standards, which differ from country to country. Choose the MPEG format and start the conversion. Most televisions are made in a way to please the general public. For that reason, everything you see on the TV had the borders cut, top, bottom and sides.

This is made to ensure that the image covers the whole screen. That is called overscan. Unfortunately, when you make a DVD, it's borders will most likely be cut too, and if the video had subtitles too close to the bottom, they won't be fully shown. The solution to that is simple. All you have to do is adjust the size the size has to be only a little smaller than the original video to fix the overscan.

Then the video will get a little smaller with black borders on the sides. Those borders will be on the overscan area and the video will show on the whole screen without the cut borders. It is always a good idea to test on the TV several different resize values for the video you are converting to know which one will best fill the TV. You can then select only a few seconds of video to convert faster, so you can quickly test the results on the TV.

After the conversion is successfully completed, the files are still not ready to be burned to the DVD. The format is correct, but the files have to be organized in order to be played in a regular DVD player. Then you can configure the chapters, menus, extras, backgrounds, and any other details you may like to add to the DVD. After that, the DVD will be compiled, a process that usually takes about 15 to 20 minutes.

Other formats will be covered later, because only a few modifications of the general process have to be made. The first step is to create a script that points to the video that you are going to convert. The script created is going to be processed by Avisynth and can be played like a normal video in most video players, like Windows Media Player. This is a basic script that is going to be used in the conversion. Basically all you have to do is paste this text on the notepad, change the file parameter to point to your movie, and save it with a name like Movie1.

The avs extension is important so Avisynth can recognize the script file and load the video. After you have done that, open the script in Windows Media Player to see if it worked.

If you get a error that looks like this:. This kind of error usually means you have made a mistake on the file name or a typo anywhere in the script. Just see what line the error is in and try to correct it. If you copied the script exactly like shown in here, it should work fine, unless the path to the video is incorrect, there is an error in the video or a missing codec.

If that's the case, use G-Spot to find out which codec you will need. For help in that, go to G-Spot. Jump to Creating a test video. OBS: The video takes longer to open through the script. But it will open much faster if you have the codec ffdshow installed.

That's good if you are opening several files on TMPGEnc Xpress , because they all can take a while to load maybe one minute each without ffdshow. If the video plays but has no sound and you have the correct codec installed, then you will have to extract the audio stream to a WAVE file.

Riverpast Audio Converter is very easy to use, but use any program you like. Simply drag and drop the movie onto Riverpast Audio Converter. Now you will have to change the script, so you can load the video and the audio separately. Use the following script and change the path to point to the correct video and audio that you have just converted.

Test it on the Windows Media Player now. You should see the video and hear the audio just fine. The next step is to test the right configuration so the video will look good on the TV. All these tests seem to be a waste of time, but with a little practice you will be able to do them really fast.

And they are important so you can know how the DVD will look like on the TV before actually having to convert the whole thing. Click on Start new project. This step is only a test, so even if you are planning to convert several chapters at once, you should not do that yet. For now, add the same script two or three times. You will use a different configuration for each one, so you can know which one will look better on the TV.

Click on Add File. Add the whateverthename. Now the following screen will appear:. Before you change any configurations on this page, you have to check the resolution of your video. If you cannot see the resolution in the properties of the file, click on Filter Marked 3 on the screenshot. In the screen that will appear, right below the timeline, the resolution will be shown for example, x Then click on Clip info above, to return to the previous screen.

For example, if your video is x , then you should select Image If you don't know which resolution is widescreen and wich one is standard , check this List of common resolutions. Even if the resolution of your video is not listed in there, its easy to know just by watching.

If your video is widescreen , select Image , otherwise, select Image Don't click OK yet. Select Cut-Edit on the top marked 2 on the image above. The following screen will appear:. What you will do now is select only a small portion of the video to be converted, only a few seconds. This way, you can convert that part of the video really quickly to test the results on the TV without wasting time.

Click on the timeline marked 1 and drag it to any part of the video that has a good image. Is even better to select a scene with subtitles showing. Then click on Set as Start Frame Marked 2. In the timeline, go a few seconds further, and then click on Set as End Frame Marked 3.

You should get something like the image shown above. The small triangles bellow the timeline restrict the video that will be converted. After that, click on Filter Marked 3 on the first screenshot. This is the screen that you will use to fix the overscan of the film.

Select Resize on the left Marked 1. This setting allow you to resize the video and create black borders around it, so they wont be cut in the TV. In Image position Marked 2 , select Center Custom size. This means the video will be centralized, and from the new edges to the end of the original size, black borders will be put.

Don't put huge borders. Just look at the original size and take 20 pixels from top and sides. For example, if the video is x , the new size should be x That is very little, so the movie won't really get stretched the from the disproportional resizes. If you want to get a calculator and find out the proportion to resize correctly, that's ok, but the difference will really be insignificant.

When converting widescreen videos, I have learnt that the videos get a better look when stretching the most possible in hight. Usually I make my widescreen videos with a resolution of x , no matter the starting size again, that is only for widescreen videos.

In the preview there will seem like the video will exceed the borders of the screen, but in the output the video will be perfect.

In this example, the original size was x widescreen. I resized it to x Why and how to fix? Region code is a major reason that a DVD player refuses to play.

If the DVD is a store-bought movie, check if it's from another region. You can change the player's region for up to 5 times. When the number of allowances reaches zero, the DVD player can play the last code you set. That means, when you import an old and scratched DVD, maybe just a little, the DVD player won't play or there are endless freezes and artifacts.

In this case, try to fix the scratched DVD with disc repair kits and try again. The problem rests with the improper DVD video format.

It can use an older format that some DVD players can't recognize, especially for older players. Plus, bad burning is also to blame. For example, if you burn the DVD at a fast speed, for example, at a 8X burning speed, it can cause problems.
