I don’t know if I qualify as an expert, but I’ve mucked around with web outputs enough to know that it is a frustrating experience. There are no standards and your video will probably look slightly different depending on the OS and playback software being used to render it.
But unlike broadcast, you don’t have to worry about “safe” colors or video levels. Black is RBG 0/0/0 and white is 255/255/255.
My optimum workflow is to still work and color correct on a proper broadcast monitor. Protect your image for TV (since it is more restrictive), then do your web outputs based on that master. You may want to add a touch of post processing to make your video “sing” on a computer screen. Some people muck with the gamma or white and black points, or contrast … its up to you. De-interlacing is obligatory, if you are working with interlaced material. Watch your material on different computers, different OS’s, different player softwares. Upload a test to YouTube and Vimeo and an iPhone. Just like broadcast, I think it’s important to view your content on the target device it will be viewed on.
Since your broadcast master is being graded to a consistent standard, you should be able to create a single set of filters you can apply to your web deliverables that will work for most, if not all, of your outputs.
But as badly inconsistent as home televisions are, I reckon that computer video is many time worse. So I no longer lose too much sleep over getting “perfect” color on web deliverables 😉
Just my two cents,
