Just for comprehension.
--bitrate 16997 would be worse quality than the original VC-1.
--bitrate 16999 wouldn't be better quality than the original VC-1 and would just waste space?

Thanks.
Well, whenever a lossy source (your VC-1) is getting re-encoded with a lossy encoder such as x264 it will introduce more/new losses and artefacts, unless you set the bitrate very very high or encode "lossless" (--crf 0) producing huge file sizes. The extra losses may however be barely visible when re-encoding with a sufficiently high bitrate or a --crf of say 12 or even less.
So re-encoding with the same bitrate as the "original" source does not mean that the quality remains the same (untouched).

If you want to preserve the quality of your VC-1 source you may just copy the videostream and mux it into a new container, like mkv or mp4 or m2ts.
