These files are restricted to 25 MB in size If you record in HD with a high frame rate you will rapidly exceed that size. When displaying a presentation file
with voice overlay, that is highly unnecessary.
A frame rate of 25 frames/sec is plenty, and resolution as low as 1280x780 is usually sufficient.
It is very easy to choose (unnecessarily) higher parameters than can
inflate the file size as much as a factor x8 or more, and we want you to choose
parameters that will fit within the 25 MB guideline.
And, as a reminder, if you have submitted a demonstration video, then there is no need to include that in your presentation video, since it is separately linked to your abstract (if it has been submitted).
Note: for projects excluded from the exhibition phase, students may (optionally) upload a presentation file by March 11. The abstract is required, though, and the deadline for initial uploads is March 11.
