  • Not a Problem
Videos look great in Preview, but run choppy after publishing.

Windows 7/ i5/4GB player

CPU peak utilization 81% during playback, drops to less than 40% after playback.

Video file is MP4. Played through browser, max CPU stays under 40%.

Please help :-)

Hi Gray
I can locate a Presentation called "Elementary Ed" - is this the correct one with the issue or do you have a preview link to the presentation with the videos?
Thanks
Hannah

I have had the same issue. Convert the .mp4 to .webm and it will play just fine.

Properly rendered mp4 files play just fine in RV. It is not RV issue, it is the tools you used to render videos.
webm is still not fully hardware accelerated whereas h.264 is. MP4 is just a container. An MP4 in h.264 will perform much better than a webm video.

This is Gray, in my customer's account. Still not smooth, even redone at 720p. Please take a look at applicable presentations on this account.

Hi there Gray,

Can you shoot an email to support@risevision.com with the link to one of the Presentations having this issue?

Thanks!
MP4 is not a codec. MP4 is a container. It doesn't tell much about the file's format.

h.264 will give you the best performance because it is fully hardware accelerated.
