Blacks are grey and colours less saturated with FV player on PC web browser.
Test page comparing FV player and other player:
http://www.ms-films.co.uk/fv-player-test/Have tested on dual screen desktop, single screen and swapped screens, problem is the same. Compared also with the local file played with windows media player
No problem with Safari on Mac Yosemite, differences between the 2 players are negligible.
Original video is PAL 1080 HD encoded with handbrake to 720P

Thanks for the field test, Mark.
We’ll take a close look and get back to you tomorrow. Quality of colour rendering is extremely important to us (I’ve made a lot of films myself and know first hand the work it is to get colours and light right in the first place).
Thanks Alec, did you manage to verify the same and have any thoughts on finding a solution?
Hello Mark,
I had a quick look at this in Windows 7 and I’m not noticing any color issue: https://foliovision.com/downloads/fv-player-colors-chrome-ie-safari.png
Could you please point us to the exact scene where the issue is most visible?
There is a lot of variables, I should have a look at this in Windows 7 at home. Did you had Flash enabled when testing this?
Thanks,
Martin
Hi Martin
Thanks for the quick reply.
This is a weird one. I see your screenshot is fine.
The problem is throughout, not any specific scene. See my screenshot of the same frame: http://ms-films.co.uk/download/fvplayer.jpg
On my system, Chrome has less saturation and higher black level. Internet Explorer is the same plus a colour shift towards more magenta.
Safari 5.1.7. On the PC outputs no video, the audio plays but the video is black.
Should be using Flash, if I right click the JW player, I can see its definitely flash. Right clicking FV player doesnt bring up flash menu, not sure, but assume is defaulting to use flash.
Thanks
Mark
Hello Mark,
FV Flowplayer prefers HTML5 when the browser supports it for the video. You can try Settings -> FV Worpdress Flowplayer -> Sitewide Flowplayer Default -> “Prefer Flash player by default” and see if that helps with your color issues.
If it does, then I expect which may have something to do with your computer hardware. These browsers use the graphics card GPU processor to show the video, so perhaps there is something set badly in the drivers.
You can also try to disable the GPU acceleration of video in Chrome: chrome://flags/#disable-accelerated-video-decode
Similar issue in Chrome is described here: http://code.google.com/p/chromium/issues/detail?id=73234&q=html5%20video%20colors&colspec=ID%20Stars%20Pri%20Area%20Feature%20Type%20Status%20Summary%20Modified%20Owner%20Mstone%20OS
Here’s also one for Internet Explorer (occurring for ATI Catalyst Control Center driver): http://stackoverflow.com/questions/25571577/html5-video-in-internet-explorer-renders-colors-incorrectly
Safari for Windows is old, outdated and no longer supported. We tested our videos on it and it worked. Are you using the latest available version of Apple Quick Time with it?
Thanks,
Martin
Hello Mark,
in IE you can try Tools –> Internet options -> Advanced, enable “Use software rendering instead of GPU rendering” and see if that helps.
I also checked this on some other computer (this time with Windows 8) and there is no color issue in neither Chrome nor IE. Both were using the HW acceleration and no problems were occurring.
Thanks
Martin
Hi Martin
Many thanks for all the detailed info. I can confirm all you advise is correct and has fixed on my system:
1) “Prefer Flash player by default” YES THIS FIXES AND IS MY PREFERRED SOLUTION
2) Disable the GPU acceleration of video in Chrome – YES THIS FIXESI also found an Nvidia graphics card setting that resolves the problem with HTML5 video. The video colour settings require changing to the following shown in the screenshot, manually selecting “Nvidia” settings specifically a Full Dynamic range 0-255, instead of using the “video player settings”

Its a shame the default Nvidia Control Panel settings have to be changed for HTML5 video colour space to be correct. Maybe something else on my system is affecting this if all your PC systems are fine on default browser and graphics card settings. BTW I have the latest Nvidia driver 344.75 which I updated last week when troubleshooting.Yes I have the latest Quicktime version installed. Slightly erratic behaviour: After forcing the FV default settings to use flash, Safari on PC reported couldn’t find the flash video file, after a page refresh it played fine. Still getting black instead of video, when flash is not forced in the FV settings. Anyway am not too bothered about Safari on PC, very few people would use.
Thanks
Mark
Hello Mark,
with the Flash preference all of the users will get the correct colors and who has no Flash installed should be still able to play MP4 file (88% of people) and I think that the chance they get bad colors because of the Nvidia driver is pretty low.
Thank you for sharing the Nvidia details.
Safari 5.1.7 on Windows 7 actually says that your video is not supported by HTML5, same for any MP4 I tried. If Flash is installed, then it plays just fine (and I don’t have to set the Flash preference – tried it on a test site). On Windows XP it shows the same HTML5 error if Flash is not present. So it appears there is some other issue.
Thanks,
Martin
