Solution to the problem of video playback and remote playback without sound in ppt

Problem description:Generally, this problem is solved in the following way: you can use the hyperlink method to directly call tools such as Super resolution for playback or convert them to the AVI format and then insert the slides. However, the two methods have their own shortcomings. The disadvantage of calling Super solution is that they are relatively compact and the demonstration effect is compromised. The disadvantage of inserting a slide into the AVI format is that the file capacity increases greatly after conversion, and the playback effect is not as smooth as before. In addition to the two methods, what are the best solutions?

Here we will introduce a new method to solve the above problems by using the "MPEG file merging" function provided by Super solution.

Solution:Add a video file that cannot be directly inserted into the slide to the "input file" column in the "MPEG file merge" operation window, specify the location and file name of the merged file, and merge the output. Although the purpose at this time is not to "merge" the file (because the input and output are all a video file), after such a process, the video file is inserted into the slide, the above error message will no longer appear. This method is also applicable to files in multiple formats such as dat.

No sound during off-site playback of PPT documents

Problem description:After I insert background music into the PPT document, I can hear the sound normally on the local computer. This file can also be copied to other people's computers but cannot hear the sound. What is the reason? How can this problem be solved?
Troubleshooting: The same PPT document can hear sound on the local computer but cannot hear sound on another machine. This is because when you add background music to the PPT document on a local computer, the PPT will remember the specific address of the relevant music file (such as "D: Lesson background music"), but there is no such directory or related background music in others' computers, of course, no sound can be heard.

The solution is simple.: Copy a certain PPT document (such as courseware .ppt) and related background music to the "D: courseware" directory, and then open the PPT document "courseware. PPT. Add the background music in the "D: courseware" directory. Select all the files in the "D: courseware" directory, right-click them, select "Add to compressed file", and follow the prompts to create a self-extracting file; add the following comments on the "comments" tab of the "compressed file name and parameters" dialog box:

Path = D: courseware

SavePath

Setup = Courseware. PPT

Silent = 1

Overwrite = 1

Click OK. After completing the preceding operations, the self-decompressed file (Courseware. Exe”) will automatically run the Courseware. PPT ", and you can normally hear the background sound inserted in the PPT document.

Other recommendations

Dubbing slides
This operation is applicable to situations where you need to repeat each slide and record the slides by yourself. For example, in the computer application ability assessment, students are not familiar with the examination system and need to explain the examination system. With this function, it is much easier. Recording procedure:
(1) select "slide show/recording narration" from the main menu ".
(2) in the "recording narration" dialog box, select the "link narration" option, click "browse", select the folder where the narration file is placed, and click [OK 〕.
(3) go to the slide display status and read the narration from the microphone while playing the slide.
(4) after the playback ends, a dialog box is displayed, "the narration has been saved to each slide. Do you want to save the rehearsal time of the slides ?", Click save 〕.
After recording, the speaker icon is automatically displayed in the lower right corner of each slide. If you select to show videos at rehearsal time during playback, the videos are automatically played.
