I received several Powerpoint presentations with (unnecessarily) very large movies embedded, resulting in files even over 1Gb.
I mean to reduce the file size. I tried the File -> Reduce media size (or the like, my Office is in Spanish) way, and it barely changed file size.
Since newer Office files are simply zip containers with a different extension, I mean to reduce the media file sizes themselves.
What I tried to replace file media2.mp4
:
- Changed
.pptx
to.zip
, - Extracted file
media1.mp4
, - Copied it into
media2.mp4
, - Replaced file
media2.mp4
inside the .zip with this alternative file (simply click and drag), - Renamed back to
.pptx
, - Checked that the movie was effectively replaced in the animation.
Is it expected that this works generally, even when replacing original media with another file with different parameters (different size, resolution, bitrate, framerate, you-name-it)?
1To replace the original movie, you'd need to rename the modified version to media1.mp4, of course, but I expect you did that. This should work nicely, even with a modified video, so long as its proportions are the same. For extra points, try it out and let us know! ;-) – Steve Rindsberg – 2019-04-17T20:08:30.967
