I’m not sure what you’re asking for.
First, MP4 is not a format but a container. It can contains HEVC video streams, H.264/AVC video streams and many more. I guess you’re trying to convert to H.264.
Then, the bitrate highly depends on the complexity of the source images. 32k and 40k ? Are we talking about video ? The unit usually used for the bitrate is kb/s, so we are usually talking about bitrates like 1500 kb/s or 5000 kb/s, etc.
The best thing to do is not to force a specific constant bitrate but to use CRF as I’ve explained there:

Thank you. As a novice I’m probably not using the right terms.
It’s the codec that causes the error and I want to change – ideally with minimal loss (I understand lossless is not possible). So I would assume it is indeed the H.264 profile I want. I’m sure that’s the one I’ve used previously as well. For some reason though it either comes out with a huge loss (something like 95% loss) – or doesn’t seem to change the codec as the error remains.
Yes it’s the video bitrate. In the original file properties it shows as 43618kbps. It seems that if I manually set this in the H.264 profile settings the max I can go to is 32617(?)kbps. So it’s quite significantly lower. I notice sometimes it’s greyed out at 800kbps, which is appalling low, and presumably related to the 95% reduction which is just unusable.
I’ll try the CRF as suggested and see what happens. Is there a reset profiles option? Just in case I’ve messed something up somewhere that I need to undo?
