Hi , I have just rendered my first video and want to convert that data into a format that will allow me to save to a CD that can can be viewed in a DVD player , which format do I choose?
Are you sure you want to put it on a CD and not a DVD?
Lots of cheaper players will handle all sorts of file types on various media. Try MPEG1 or 2 and burn the CD as a data disc containing that file. Some players will show a menu listing the file names and let you select one to watch. Lots of higher-end expensive players may balk at it and tell you it's not a valid disc type. Strange, but it does help justify spending less than $40 on a player!
A lot of newer players handle DivX. Usually they'll have a sticker on the front that announces this feature. If so, try that format.
Vegas Studio also lets you burn what's known as a VideoCD, which allows a limited menu. Some more expensive or older players may be happier with this than with data discs.
In general, burning video to a CD and expecting a DVD player to handle it is a crap shoot. Try a few different formats in a few different players and see what works. Better yet, make real DVDs on DVD blanks and you'll have a lot more success.
If you really need/want to put this on a CD .. there are two options .. Video CD (VCD) or Super Video CD (SVCD)
Vegas only has the option for Video CD which is of a lower quality than Super VCD .. but still 'reasonable' ( some say it's around the same as a VHS tape .. maybe a bit lower ) but you could output in a SVCD quality file and burn it with another piece of software.
