What pixel format ?
What type of content ?

For 8bit 4:2:0, it will be x264 or ffv1 using long gop

Long GOP will almost always produce better results, so that rules out things like lagarith. The exception will be null frames. Content that has lots of identical frames. Lagarith "null frames" option will put it over the top
