Lower Bitrate of Uncompressed AVI Render?

LA Media wrote on 2/13/2015, 12:26 PM
Hello there. I just got a Tricaster and I'm using Movie Studio 12 to create show intros with alpha channels. To make the alphas work with the Tricaster I need to render them as uncompressed AVIs. The codecs that Newtek (the Tricaster manufacturer) gives you create files that give your computer errors if they're living anywhere on your hard drive so I can't use them with Movie Studio. The problem is that rendering to an uncompressed AVI creates files with an extremely high bitrate. If you try to play them in the Tricaster they are a stuttering mess. The Tricaster even tells you that there are problems because of the high bitrate. So, is there any way to change the bitrate on these renders? I've looked all over and haven't found a way to do it. Any help would be greatly appreciated.

Bitrate doesn't really apply to uncompressed files.

If you want smaller files that are easier to play you'll have to reduce the frame size, the frame rate, or the bit depth.

No, several codecs in Vegas render alpha.
The math for Uncompressed does not allow bitrate control. It's fixed.

Which other codecs? I can't seem to find any.

Where do I do that? I don't see those options for uncompressed AVIs.

There are AVI and othercustom formats on the VIDEO TAB.

Yeah, but the only options in that drop-down that let you render the alpha is uncompressed (won't work) and CineForm. But I read on another board that CineForm is bad for alpha.

Just curious, but are you going to be using your transparency file as the finished file to play in Tricaster? If it is the finished version then i'm not sure why you need transparency. And if some processing is going to be done to combine it with some other file in Tricaster, wouldn't the output of that combination be the file that's played? And if so, that combined output can be in a format that Tricaster plays well, and it won't matter if the huge transparency file doesn't play smoothly.
