45 Frequently Asked Questions in Audio and Video Usage

1, why can't DVD discs with audio and video recordings be played on home DVD players?

There may be several reasons. A. when burning a CD, set it to miniDVD format, which is not supported by some DVD players. B. burning DVD discs with writable discs is not compatible with DVD players. C. too fast recording speed will also cause poor disc compatibility. D. some players don't support DVD+R. you can try DVD-R. If you don't turn off the antivirus software when burning, it may also make the compatibility of the CD worse.

2. When recording a long program, sound and shadow will form a seamless video. Why do some playback software pause at chapters?

Some video playback software can't support chapter form well, so you can try using WinDVD or Power DVD, and the playback effect will be better.

3. If the capacity of the CD is exceeded, will it affect the quality of the program if it is compressed and burned?

Reducing the code stream can increase the duration, but it will reduce the program quality. If the quality requirements are high, you can burn it into two CDs. 4. What do you mean by "Don't convert compatible MPEG files" in the burning project?

Please select this option. When the file you collect is a standard MPEG file, there is no need for secondary conversion, which saves a lot of time. For example, clips selected from a DVD during editing can be inserted into your own video and will not be rendered later.

5. The sound and picture are synchronized when editing, but some sound and pictures are not synchronized when burning?

A. Before editing, you must close the antivirus software and stop other software running. If you have an optimizer, you can optimize memory before editing compression (rendering). B: The recording speed is too fast. You can try to slow down to 16 or 8. High-speed burners are very useful when burning data discs, so you must slow down when burning video discs, otherwise the compatibility will be poor.

6. How does the edited video file form a new video file?

You can choose to save the cropped video in the Material menu, and the newly generated video will be displayed in the material library. When making the opening and closing credits (as in TV series), you can generate the required segments one by one in this way and then use them.

7. How to separate the sound from the video shot by DV? Or re-edit?

In the editing panel, click Split Audio to split the audio. You can then render the audio and save it as a new audio file. In this way, many good audio files can be obtained by using the audio in the ready-made DVD video files.

8. Which file format has the highest quality when collecting? Which encoding works well after editing?

DV format should be selected when collecting, so as to obtain high-quality video material. For hard disk DV, it is best to copy the original file directly to the computer (although it is a MOD file in MPEG format, which is different from general software compression, but it is a high-quality video compressed by hardware. ) After editing, it's best to select 6M code stream when generating DVD files.

9. Is the definition of burning CD related to the choice of CD and burner?

The clarity of optical discs is not necessarily related to optical discs and recorders. It is only related to the edited lens material and compression.

10, audio and video can convert the programs on the old VHS into VCD or DVD?

1 1, why does the date and time display that can be seen on DV display screen and TV disappear after being input into the computer with 1394 line? How can I make it reappear?

In fact, only the video stream and the character stream (time and date) are separated. Ordinary players don't read character streams. But you can use other software to turn it off. Like vDTS. This software can easily type the time and date of the camera on the screen to get the time and date you want.

12, how to use the chroma key?

Chromaticity keys are mainly used to cut images relative to single colors (green, blue, etc.). ) background. Please put the video to be cropped on the superimposed track first, click the "Mask and Chroma Key" button, check the superposition option, and click "on the monochrome background of the preview window with the eyedropper tool to crop the background. That's what weather forecast programs do. With it, you can also make your own MTV.

13, why is there a hint that the link cannot be found? Because the path of the project file is absolute (only the initial file path can be remembered), once the material is moved or the file is renamed, the project file can't find the path. For the convenience of editing, it is best to create a new folder, and put the videos, pictures, music, explanations and other materials to be used for editing in this folder for management.

14, what should I do when I run out of hard disk space when I am ready to burn?

Versions after Huisheng Huiying 7 can only run at resolutions above 1024×768.

17. is it not as clear as professional software to edit and burn into a CD with "audio and video" software?

This is related to your pre-setting and the code stream selected during compression. Audio and video 1 1 supports high-definition formats, such as HD DVD and Blu-ray DVD.

18, why can't I open the MP3 music file?

Maybe the bit rate of the file is high, so you can use the conversion software to reset the bit rate to 128 or lower, so that MP3 files can be successfully added to audio and video.

19, when capturing a DV signal, a prompt "DV code conversion is in progress, press ESC to stop" will appear every few minutes, and then the software will automatically empty the DV code buffer, making the capture impossible. What happened?

This is because the computer configuration is low, such as low hard disk speed, low CPU frequency and small memory. You also need to turn off anti-virus software and firewall and stop all programs running in the background.

Yes, when you burn a CD after setting the parameters, you still need to reset the path of the working folder to a partition other than the C disk.

24. How to set up the system?

Set the system before editing. First, enable DMA settings for IDE disks. Direct memory access (DMA) can avoid frame loss when capturing. You can find it in the properties of the device manager, advanced settings: the transfer mode is DMA. Disable write caching for hard disks used for video capture. Can be set in the device manager.

25. Is the project setting important?

Yes, it is very important. Before editing, you should set the project, including improper settings such as general and compression, which will lead to video editing errors, poor quality, prolonged rendering time and CD burning errors. Therefore, you should set the project before each edit. Not only audio and video, but also other editing software should be set up in advance before use.

26. Why does the video sometimes have no sound when editing with audio/video 10?

This problem has indeed been encountered. I estimate that the software of Huisheng Huiying 10 will have loopholes or defects when running. Huisheng Huiying 9 and previous versions have not encountered this problem. When there is no sound, reinstall it and the problem will be solved.

Uninstall the third-party decoding or encoding plug-in before rendering the generated video file.

3 1. Solve the problem that AV 10 cannot import utf subtitle files. The UTF subtitle file produced by POPSUB cannot be imported in audio/video 10, and the prompt format is wrong. In fact, as long as you choose SCR format when saving files in POPSUB and pay attention to changing the encoding method to ANSI, you can correctly identify them. In addition, there is no need to change the file name at all, just change the extension SCRr to UTF directly when outputting.

32. Why can't Nero burn dvd video files produced by the audio-visual studio? Nero pointed out: "If you want to make DVD video discs from video files on your hard disk, you must use NeroVision and other production tools."
