This isn't meant as a play on words... read slowly.
What I've noticed:
If you previously had a region selected on the timeline, for your current project or another, then render, then go to render again, but this time you want to render everything, there is a check by 'render loop region only', but that option is grayed out in the render as selecton window and isn't active.
In other words is isn't selected, (this time) and the render will be the whole project.
If you go back and deliberately select an area to render, then click render as, the selection will not be grayed out as you would expect.
However, If you now uncheck 'render loop region only' Vegas will go on to render the whole project, again as expected.
If you stop Vegas before it has a chance to finish rendering, and now again go back to the render as option, the option to 'render loop region only' will no longer be grayed out and the little box will have no check at all.
A bug? In my opinion not really, but maybe a little confusing. Did older versions do this? Heck I don't know. I have trouble remembering what I did yesterday. <wink>
Thanks as always Bill. In my other post I followed your suggestions, but Render To A new Track only rendered part of the project so I ended up not saving the changes and deleted the new track.
So I tried selecting the "Reduce Flicker" and "Force Resample" again for the project figuring I would just render it and because Render Loop Region was greyed out, I was afraid it wouldn't render it all and I would continue wasting more endless hours just to see if I could reduce horizontal lines with jaggies and flicker in the video. Here is a link to the other two posts:
A minor nitpicking point. When you select 'events to end' the track highlight color changes indicating you've selected a range of events from the event you clicked in to the end of the timeline. I like to use purple or red because they probably are the most obvious changes. However once you select events to end and then start setting switches, there are no additional visual clues telling you that's what you did, so I guess a matter of trust, that Vegas will do it.
So as long as you see that the track has changed color, and is the same color all the way to the end, (meaning all the events are still selected) then you can safely assume whatever switch you changed in the first event to the end does in fact change them all.
What can get confusing is if you move events from one track to another then the events take on the new track's highlight color. So if you move a bunch of events from a track that's using purple highlights to one that's using green, then the moved events take on the green hightlight, but whatever switches you set remain until you change them again either as a group or alone.
