Render colors doesn´t match

Hi there,

I'm new in Vegas and I think it is great !

But I'm getting into a color diferences. When finished the edition process an proceed to the final render of my work (even into an AVI Uncompressed format) the final result appears very clear (ligthness too high and the colors doesn´t macth exactly). I`m appliying video filters to the video bus to adjust the video quality.
Cliking the twin preview window to see in the same window the video FX applied and not applied, the final result looks like the FXs where bypassed.

I'm comparing the result between the Vegas preview window and the Windows Media Player, both opened at the same time.

It's true that I'm working with a video captured form an TV capture card and is not the best quality neither the best resolution, but isn't true that I'm supposed to get the same result looked in the preview window and the media player ? (considering the codecs and compression impact, of course).

Please, can anyone help me with these ?

Thanks

Andrés

Fx filters can be applied 3 ways in Vegas:

1. Dragging a filter to the preview window effects EVERYTHING.
2. Dragging to the track header effects just the track dropped on.
3. Dragging to an EVENT on a track only effects the event.

This allows great flexability.

There's also a visual clue. When you drop a filter the FX icon turns green. So if you meant to drop on an event its its icon lacks a color change look at the FX icon on the header. It got applied there. Undo and try again. This has to do with how well you do or don't drag and drop. Its fairly easy to 'miss' your target if you left go of the mouse too soon. If you drop and drag over the preview window its' FX icon should turn green.

Finally its possible to drag and drop the same filter or actually other instances of it in multiple places. I use this to advantage if I've made a bunch of changes to a range of events. If I later decide I didn't like the effect I can drop the filter again on the track and with just a couple quick adjustments modify all those events by either adding or taking away from the event dropped filters.

As far as video looking different in Media Player, it depends if you're looking at your source video while comparing what Vegas did to it. Media Player is showing some rendered results. The preview window always shows the effects of what you're changing in "real time" so you can see. Also toggling the split screen switch above the preview window gives you a before and after view right in the preview window. Once can use the cross-hair cursor to draw an area of the preview window you wish to compare. So if you want you can divide the screen in half or just make a different area smaller or larger.

I belive that WMP also has individual brightness controls. Maybe those are messed up.

#4) Directly to the clip in the Media Pool - affects the clip no matter where it is on the timeline.

But since the Media Pool is mainly designed to show SOURCE materials, why go that route?

It's a perfectly valid way that FX can be applied and there are certain cases when you NEED to use the Media Pool. (i.e. the timecode FX if you want original timecode).

Or when you want to color correct a whole clip. I've done that before.

BillyBoy, The effects were applied right. Splitting the previre window I appreciatte the difference between the before and after.
Once rendered, the output viewed in a player (Windows Media player or Radlight) looks more like the bypassed FXs preview half than the applied half.

Am I missing something ?
Thanks.

I'm think is not a player issue.
I'd tryied with several players.
It's true that differences goes messing up with the player picture controls but I'm trying to get the optimal picture without the need of adjusting.
I'm not doing this to printout to tape, just for computer viewing.
It seems to be an essay & error matter.

amunioz,
when all else fails try a test!
Make one of your filters extreme so there's no way you can miss if it's applied or not. That way you'll immediatley be able to tell if its actually appearing in the renderd output.

Also I'd suggest bringing you rendered output avi back into VV and look at it there. Only reason I'd suggest doing that is so your uing the same 'instrument' to make the comparison. Also try comparing before and after in WMP for the same reason.

I'd also suggest there maybe quite some difference in how WMP displays things and VV, You first need to elimiate that as being the root cause of what you're seeing.

Hi farss,

You're right !!!
I'd rendered a portion and inserted it into Vegas and both looks like almost indetical (surely compresion issues).
All the problem resides in players.

But now, is there a way to obtain a video for web publishing purposes which looks exactly the same as I'd edited. You know, is not only a brightness matter. Also differs in color, saturation, etc. It's very different.
I'm trying to obtain a video that not requires any adjustment for the most of the users.

Thanks.
