For certain they’re not aac?

Container and stream fps likely differ, use virtualdub.

Main level 3 mpeg4 avc, crf 22, 24-26 if graphics or animation.

854 wouldn’t work for SD if it’s square pixel, 720,400(408) is max for that. Or did you mean anamorphic?

MP4 container is too hardware tuned and operates on a lot of assumptions, particularly with sync. Save to MP4 valid codecs in an MKV then remux into an MP4, it should result in more software friendly time stamps.

Break some rules, use handbrake, crop 8 from the height and target 536 height(this will do a very fast 2-1 reduce rather than an actual resize), check maintain aspect ratio, code to mpeg avs quality2 or normal profile(important for speed) mpeg avc, quality 18, higher if desired. Use crf instead of bit rate and save to mkv. If MP4 is used be sure to uncheck web friendly. It will encode at ~ 150 fps on a modern system. If more flexibility is needed, avidemux runs at similar speeds but again avoid resizes on HD as they are single threaded, once in SD the resize penalty is definitely more manageable.
