source: dv/avi
rendered , uncompressed avi
viewing on the monitor , using 3 diffreent player with the same result : wmp, bs player and videolan.

If i put the rendered file on the timeline it looks just like the orginal one ???

here is a captured frame (best quality) if I set the contrast to +12

here is the rendered file set to +12 of contrast

the difference is quite obvious

why would the rendered file look the same if i drop it on the timeline ??

thanks for your time

This is a feature of the way that DV AVI files are played within those players. As I mentioned in my other post... Windows Media Player and others it seems) do an awful job of displaying DV AVI Video. This is a feature of the fact you are displaying (lkely) Interlaced video footage that is non-square pixels) and the players just aren't up to it.

Is this the way the rendered video will be viewed (on a PC)? Or will they be viewed on a TV? If TV - then you need t preview your rendered file ON a TV as if you make any editing decisions (such as messing with the contrast/brightness) based upon how they look in a player on the PC - you will likely make bad decisions.

If they will really be playing on a PC - then I WOULD recommend you adjust the brightness / contrast etc so that it looks good on the PC - however it woudl be unusual if you were to render to DV AVI format if that were the case. It would be more likely you would render to WMP or some other web/streaming format.

Incidentally did you <really> mean that you rendered the file as an uncompressed AVI file? As there is likely very few reasons you would need to do that. Render to DV AVI (which is compressed) maybe... but not truly uncompressed.

Best thing to check things with are the scopes in Vegas.
Put both clips on the T/L on tracks once above the other and align so the frames match. Mute the top track to swtch videos and watch the scopes. I prefer the histogram as it gives me a good feel for what's going on. Others who've worked in broadcast will be more comfortable with waveform or vectorscopes.

Agreed...

In this case... Phil2Film has confirmed when he looks at the source/render in Vegas they do in fact look identical... so in this case I think the issue is the player rather than anythign Vegas is doing.

Hi guys,

Just woke up and got to get to workalready , will do all those test tonight and come back with the result

Thanks for your time guys.

One thing that still puzzles me though is that this never happened before. For the past year I've always rendered a part of my project to look at in any media player and it was always fine.

See you tonight

Phil

Ok guys,

Back from work. So I looked at the historigram with both the rendered file and the original one in Vegas side by side. The historigram is pretty much the same.

Now if I render to uncompress dv/avi and throw that in let's says Vdub and compresse it with divx the result file has the same contrast as the original one in vegas.

So I guess all my media player are screwed HIHIHI

Thanks a lot for your input guys.

Phil

Phil,
What kind of video card do you have? You may want to check any color correction settings in your display control panel. For example, most nvidia cards have a color color correction control that looks like this:

Control Panel snapshot

You can apply changes to the desktop, which is pretty much everything, or to an "overlay", which only applies to media players that use hardware overlay. If the overlay settings are different from the defaults, then any changes you make here will apply to all of your media player windows, but not to the vegas preview window. So it can cause exactly the problem that you're describing.
