Hi, KaieCie.
I understand that you are trying to insert an MP4 file into your presentation slides.
I'll hwlp you.
1.Which way are you going to add them to the slide?
- What happens after you insert the video into the slide?
- Are the files saved on the desktop?
Make sure you are following the steps correctly:
• Insert a video stored on your PC
→In Normal view, click on the slide on which you want the video to appear.
→On the Insert tab, click the arrow under Video and click Video in My PC.
→In the Insert Video box, click the desired video and then click Insert.
• Link a video stored on your PC
→In Normal view, click on the slide on which you want the link to the video to appear.
→On the Insert tab, click the arrow under Video and click Video in My PC.
→In the Insert Video box, click the file you want to link to, click the down arrow next to the Insert button, then click Link to File.
NOTE: To help avoid corrupted links, it's a good idea to copy the video into the same folder as your presentation and then link them there.
Best Regards!
Hillary.
