Although this is already an old thread it might be useful for others to give an answer to this. I often read questions about rendering in batch mode in Revit. Or remarks about that still missing feature in Revit. It took me quite some time to figure out how things work precisely and maybe this could save you some time and prevent some stress.

As mentioned elsewhere the solution to render different point of views in a batch mode is to gather these together in one walkthrough and to render the walkthrough instead of different views. The point is that the number of frames in the walkthrough should be identical to the number of views that you want to render. See properties, other, walkthrough frames. So when you have 5 interesting views than the total walkthrough should consist out of max 5 frames. (these are also the 5 key frames) You can change the position, direction and camera height and so on, on every different key frame. Change these while editing the walkthrough in a combination of windows. For instance sections for height and plans for position and a walkthrough view for controlling the results of manipulating active camera and path parameters in the other windows. 

Normally the number of frames in a walkthrough would be much higher between the key frames (15 fps) and you will have to change that manually when else the program would render all those 15 frames in high quality render mode and this might last weeks of rendering.

When the walkthroug is ready you'll have to select it and export it to jpeg instead of avi. So in this way only the interesting point of views will be rendered in jpegs in reasonable time.

I hope this is useful to you and otherwise you can ask or make comments to complete my short explanation.

Good luck

Just to add on to BouwbureaSkald's explanation. First set up your walkthrough and choose your 'key frame' locations. In the example shown, I have three. Then open your walkthrough and under properties, select 'Walkthrough frames' and change it to match your number of key frames. Then go to export, walkthrough, and when the files browser opens, change to file format to a picture file.
