This video was shot in 720/30p, kept in that format through edit, then rendered to a 6Mbps Windows Media 9 at 1280x720x30p.

I was trying some more widely recommended render formats, such as MP4, h.264, but gamma or setup wasn't tracking right (washed out blacks), so, rather than solving that problem, I worked around it; having previously had very good results with 720p WM for large-screen projection.

At the XR high-rez setting this clip is pretty close to what I saw when editing it... I'm pleased with the results and with Exposure Room.

BTW, I have the same video up on YouTube - there's really no comparison.

Seth do you use the Studio to RGB level settings when going to Exposure Room?

Yes, SOP for me is to use the Studio-to-computerRGB setting in the levels filter when preparing for on-screen playback.

I just took a quick look at the MP4 I'd done first for this project. Levels are off (blown whites, grey blacks) in QT player, however, levels look fine in Vegas and it scopes well, but shows some non-jaggy ghosting in areas of rapid motion. So, levels may be a QT player problem, but there's something also going on with maintaining progressive.

I'll be interested to check this on a mac with QT, but if the player can't be trusted as a reference I'm a little leery of what exposure room may do with it. I'm certainly happy with the WMV intermediate and the final look.

***edit***
It does look like the exposure room encode to flv from my wmv has very slightly flattened things out - maybe 5 ire units. Seems to me that an actual range of 0-95 IRE may be better than 0-100 for an intermediate render. I'd like to do more testing on it.

I have put up FLV, WMV and Mpeg4 and to me WMV at 5-6mbps seems to be it. however they still compress again into flv, like any video sharing site with some tweeks. I think Vimeo does a better job compressing. I am using Xvid4psp to convert an avi to flv and that works. still get some artifacting tho. The mgeg4 seems to the worse for me. haven't tried avchd yet

so I guess the best way for me was to just convert to FLV first, then it uploads. its still not as crisp as on my monitor, or compared to what I have seen on ER, but it will do for now, till I can get it tweaked a bit.

try this, render your clip thru vegas to avi intermediate, use the same size as your camera produced, I render to avi 1440x1080. if you download Xvid4psp here are settings I use. from each dropdown select flv, video, vivid,flv1 hq ultra, audio go into audio settings, use 196 or 224, go into video and set size to 640x360, render out. don't forget, when you use a video sharing site, any site, they are going to compress it again when going thru their conversion process. but doing it this way its only compressed twice, since the avi was not, your chances of better results are there,

I just signed up to ER yesterday.. I was trying an experiment with really saturated colors and massvise file size to see how it would look...

This was a 1.5 gig MP4.. looks ok I guess... rendered in vegas. I don't know how some of these guys make their video looks so sharp and colorful when posted on vimeo or ER... My looks fine before uploading, but online... I am not happy with them.

Well, obviously you were color-correcting with a fairly heavy hand, using cc for efx...

Mostly, I liked the color, but obviously I'm not comparing it to your original.

Exposure room, Vimeo, Youtube - they're all using the original Sorenson Spark codec because it's free. I think this is where you're losing color saturation, especially sat in the highlights. The VP6 codec would be another story, but so far as I know none of the free sharing sites are using it because of cost.

One thing to experiment with is limiting luminance by 5% or 10%. It seems to help highlight saturation, at some cost of overall contrast range.

yea see on vimeo I didn't mess with the colors at all and it came out like this...

The Ring Of Fireflies on Vimeo

it's nearly black and white.. LOL So I made the colors too strong on purpose thinking it would look ok after ER took out some color.. only it seems I over did it a bit.. :)

Some basic info.If you go thru Exposure Room and check out other videos, no matter what the size started with they end up much smaller, that could be the issue, Vimeo has their conversion down better than ER, and they convert with the files larger.Its too bad the best HD video site is no longer around, it was HD Hosting.com I think. I found it thru the forum I use for my video sharing site. I was just about ready to put a site up with their hosting and all of sudden GONE, It put vimeo and Er to shame, but! never could find out what happened. They said they had worked on the HD conversion for two years to get it what it was. These are the basic scripts which make a video sharing site run, they all have them in some variation:

# LAME MP3 Encode
# Libogg
# Mencoder
# Flvtool2
# FFmpeg
# Libvorbis

I can't write code, but sites who have script and code writers tweek these

On this one I started the project as 32bit flaoting point, and only bumped the saturation a little bit... Looks good to me..
