（3）Unsupported or Not Recommended Content:
Flash Animation (SWF files) are not supported.
WAV, OGG, and other audio formats are not supported.
It is not recommended to use GIF animations larger than 1MB, as it may cause performance issues, screen flickering, or crashes on low-performance machines.
SVG, JP2, BMP, and other image formats are not supported. Only PNG, JPG, and GIF formats with good compatibility are supported.
Speaker notes are not supported. Speaker notes may cause animation failures on slides.
（4）Text Content Guidelines
（a）Font Selection:
To ensure consistent content display across different platforms, it is recommended to prioritize using system default Chinese and English fonts.
Recommended mixed text fonts: Microsoft YaHei, SimHei, SimSun, Dengxian, KaiTi.
Recommended fonts for pure English text: Verdana, Calibri, Courier New, Times New Roman, Georgia.
（b）Text Formatting:
Justified alignment for text is not supported.
Due to compatibility differences in Office versions, to ensure maximum compatibility, text boxes should have some extra space to prevent line breaks in different versions.
Multiple fonts within one text box are not supported as it may cause misalignment of converted text.
Advanced text effects such as text animation or 3D effects are not supported.
For fill-in-the-blank questions, use double underscores (Shift + hyphen key) for underlining. Using spaces and underline styles may cause page misalignment.
Text alignment should be done using text box alignment methods. It is not recommended to set line heights for content alignment.
（5）Guidelines for Image Insertion:
Avoid using PowerPoint's image editing functions on GIF images as it may prevent GIF animation playback.
Unnecessary content and elements should be deleted. It is not supported to make them invisible or place them outside the slide, as it may affect the normal content.
Extremely high-resolution images are not supported, as the conversion process will automatically adapt the images, resulting in reduced image clarity. It is recommended to use images with sizes similar to the PowerPoint slide display dimensions.
The size of inserted shapes should not exceed twice the display size of the PowerPoint slide. Very large shapes may cause conversion failures.
（6）Guidelines for Audio and Video Insertion:
Only MP4 format is supported for video insertion, with a resolution of 720p or lower.
Customizing start and end times for audio is not supported. Currently, only playback from the beginning is supported.
Video elements do not support shape effects such as shape fill or shape outline.
In PowerPoint, right-clicking on a video and selecting "Format Video" is not available.
Videos do not support automatic playback by default. To resolve this, right-click on the video, click on "Start", and choose "On Click".
Pages that contain videos do not support animations.
Non-functional links in audio control elements can cause conversion failures.
(7) Presentation Mode Considerations:
Looping of the presentation is not supported during playback.
Narration or voice-over functionality is not supported.
Animation effects are not supported during the slideshow.
Solution:
Enter "Slide Show" mode
Click on "Set Up Slide Show"
Uncheck "Loop continuously until 'Esc'"
Uncheck "Narrations, ink, and laser pointer"
Uncheck "Animations"
Uncheck "Disable hardware graphics acceleration"
(8) Transition Effects Considerations:
It is recommended to use fewer or no transition effects, and the duration should not exceed 1 second. To resolve this, uncheck the option "Advance slide" in the "Transitions" tab, and set the "Duration" to 1.00 or smaller.
Automatic playback of transition effects is not supported. To resolve this, check the option "On mouse click" in the "Transitions" tab.
Transition effects do not support sound. To resolve this, set the "Sound" option to "No sound" in the "Transitions" tab.
Recommended settings:
(9) Animation Effects Considerations:
Short continuous audio (within 5 seconds) playback is not supported.
Solution: Use longer complete audio files.
Animation effects with a permanent pause on click are not supported.
For example, if you have a spinning wheel animation for a lottery effect, it is recommended to use alternative forms such as opening a treasure chest or smashing an egg.
Animation effects applied to text may cause display anomalies and are not supported.
Click events specific to text elements cannot be triggered. Solution: Use the text box as the clickable entity.
It is recommended to limit the number of animation effects on a single slide to 10 or fewer. Too many animation effects can result in decreased system performance.
Grouping elements after applying animation effects are not supported. Solution: Apply animation effects to the grouped elements after grouping them.
