How do I explain this...
I render HDV clips in Vegas 7 to a 720p quicktime photojpeg .mov and preview it with quicktime...fine. Works but there is always a slight difference between what I see in Vegas preview and how it looks played back in quicktime. The quicktime version has slightly less contrast...almost a very subtle grey casting to the image that tones down it's 'pop' so to speak.
So I do things slightly differently. I take the same clip and render it as an 720p avi and watch it in windows media player. Again....there is a subtle difference between what Vegas shows in it's preview and what the media player playback will look like. Instead of a loss in contrast there is actually a slight increase in contrast and generally slightly more saturated colours.
What really confirmed it was I windowed both versions of the final render (AVI and MOV) and laid them around the vegas preview window to compare the same frame of each view.
There were very remarkable differences. The quicktime player had the lesser contrast compared to Vegas preview but pretty acurate colours. Media Player with the .avi showed the increase in contrast and just that hint of higher color saturation. All settings for each player were flat/default, latest versions, and the LCD monitor is calibrated.
So my question is this......Do the media players (Quicktime and Windows Media Player) apply something to the finished files during playback that would affect the look of the videos in these ways?
Bringing either of these files back into the Vegas timeline and previewing shows them as identical in all ways image wise so the players themselves are doing the change. Using the scopes in Vegas show insignificant differences...visually in the preview window they are identical.
Has anyone else seen this??? Does this happen with other editing software/media players??? What am I missing?
