PowerPoint offers the ability to export video function, this feature, slide (may include record timing, narration, ink strokes and potential laser pointer, etc.) can be exported as .mp4 files, but this feature seems to be a problem:
- When the need to export using the complex as a video slideshow in the background or insert a picture, video export, in some cases, mainly under Android device, using a variety of different ways to decode, can not achieve complete control (such as fast-forward, skip, etc.) functions, you might not be able to jump, it may only achieve a certain span of time (probably in the range of 5 ~ 10s) outside jump beyond this time span can jump, otherwise you can not jump . In addition, when the export of video resolution will be reduced. Moreover no insert a picture, there is no problem when the slide with a white (or solid color) background.
Export video in problem situations, normally in Windows 10, many pages are normal. Although in most cases normal, but still it can be inferred that the reason is not that player (or decoder), but the video itself is the problem, because on Android devices is not always abnormal, abnormal only in the case, and clarity while also reducing.
It is not known causes and solutions to the problem, but should pay attention to this issue because it affects the normal use of:
- Played on Android devices is a very common form
- Even if the normal control in other cases, the video resolution is reduced
