I'd like to recommend a feature to be added to the PowerPoint application. NDI is a high quality, low latency professional video IP format that I think would be a good addition to this application. I would allow you to share the output of PowerPoint on other peoples computer using a free NDI Monitor application or send the output into professional video production solutions.

The Skype team at Microsoft has added NewTek NDI support into their product. PowerPoint would be the next product that I think should be enhanced with this royalty free technology. You can learn more about NDI here. https://www.newtek.com/ndi/

Please consider adding support for this.

When pasting Excel graphs into PowerPoint as a linked object, the Excel graph will shrink to 50% size or grow to 150% size if any change is made to the Excel file it is linked to (in our experience, the object shrinks ~90% of the time). The dimensions of the object change in PowerPoint, but the scaling remains at 100%. In order to return the linked graph to the correct size as created in Excel, all Excel worksheets need to be closed and the 'Update Link' needs to be selected after right clicking on the graph. The linked graph will then grow or shrink to the correct size.

Scaling remains at 100% throughout this process unless the size is manually changed in PowerPoint. If the graph is resized in PowerPoint and then the graph link is updated, the graph will change to the size of the new scaling relative to the correct dimensions (i.e. if the graph was 2x4 in Excel, shrunk in PowerPoint to 1x2, and then was manually changed back to 2x4, the scaling would be at 200% so when the graph was updated, the graph size would increase to 4x8).

Below is a post in another forum that describes this problem happening to all metafiles pasted into PowerPoint:
https://answers.microsoft.com/en-us/msoffice/forum/msofficepowerpoint-msowinother-mso_o365b/powerpoint-2016-automatically-resizing-charts/c4072dd1-58d7-4c95-86bb-39972e1a6656?page=2
"I draw charts in Excel and paste them into PowerPoint presentations, typically as Enhanced Metafiles, which has never posed me a problem with previous versions of PowerPoint.
However, in the latest version when I paste a chart as a Metafile / Enhanced Metafile its height / width become ~30% larger than the Excel original. Why? This does not happen when it is pasted in as a PNG / JPEG / GIF / Bitmap - the dimensions stay the same.
This problem does not apply in Word 2016 - the paste sizes are the same regardless of format"

The edit Links to Files dialogue box needs a refresh.
1) you cannot even scroll left right and successfully get the often very long file path displayed; identifying the right file when trying to update charts in ppt is not easily possible. Recommendation: fix the display of the content in this window that the information gets actually shown. Also useful would be the possibility to resize this window to be able to avoid scrolling at all.
2) add a reference to the object in this "Links" window, so you know what object on what slide is linked. A little preview box when you mark an item would be outstanding.
3) Add a quick access in Design - Data to edit link of the object(s) just on the page selected. This should go hand in hand with the possibility to open and refresh from the context menu (right click)

Powerpoint's interface is really suitable for decorating tables, but the edit we can do to the table is very limited.

1) The table template is quite old-fashioned, it would be great if PowerPoint can provide table design template that is more up to the current aesthetic

2) While some would like their table looks more 3D, shading is a better tool comparing to emboss to make the 3D appear more natural. However, it is not possible to do different shading to the cell alone, the current version ppt only allows to do shading for the whole table and I find this very inconvenient.
