How to make background "white" in avi/movie

I'm trying to render an animation and have the background white. I have the background set to white, so it is whiteish, but I want it to be true white #fff. I assume the lighting affects the background color so you get a kind of grey white. Anyone know how to make it white white?

    A background colour shouldn't be affected by scene lights, but it might be affected by gamma settings in DS or in the editor. Better to render to an image sequence saving as .png or ,tiff so that you get an alpha channel, then use that to apply a background in your editor.

    Thanks for the response.

    I need a video, not an image sequence. How can I fix the gamma before I render to make the background in the video white?

    An image sequence is made into a video in your video editor. It's generally considered good practice to render to images - you can easily fix issues by editing one of more frames, or by rerendering; you can break a long render up into batches and assemble the result; if the application crashes you can resume from the last good frame; you get an alpha channel to aid with compositing.

    As for the gamma, I don't know if that's the issue - and if it is I don't know if it's the setting in DS or in your player. What are you Advanced render settings in DS?

    Hmmm, looking into it in more detail, it seems the video is fine, the issue is that Chrome and Firefox both seem to display white as grey.

    Seems to be a browser issue, hopefully they will fix it. I can't find any good workaround.

    That sounds even more like a colour management issue.

    Just to answer my own question in case anyone else has the same issue in trying to add video to a website using HTML5 video.

    I was rendering to an avi from Daz3D, then converting the avi to an mp4 video using Handbrake. mp4 works on all 4 web browsers (Chrome, Firefox, Safari, IE), but the white background became greyish on all 4.

    I am now rendering to a png image series, and then using ffmpeg to convert the image series to mp4 and webm. The mp4 has a white background on Chrome, but still greyish on Firefox (but a lighter grey). The webm format is supported by Chrome and Firefox and supports video with a transparent background, this was my goal, so it seems to be the best option. Only Chrome supports webm with transparent backgrounds right now, on Firefox the background is white, so also solves the grey background issue.

    Here are some examples of the videos (click on the editor to view the video).
