Upper limit on FFMPEG / libx264 frame sizes?

Question

I am trying to use FFMPEG to transcode videos with very large frames (4096 x 4096). This short video is only two minutes, but the original video file is 15.8 GB. (Video is an animation designed to project onto domes of a planetarium.)

The source file is Quicktime MOV, which contains uncompressed Photo-JPEG images (with sound, too). When I tell FFMPEG to transcode my MOV file to an MP4 file, it simply says:

Error opening encoder for output stream # 0: 0 - possibly incorrect parameters, such as track_ bit, speed, width or height

Not very useful, but yes, I checked that all parameters are correct and / or default. In fact, if I changed the requested output size to 2048x2048, then everything will be very good. . Therefore, I suspect that the encoder has an upper bound.

I'm sure. Any suggestions that lead to a successful conversion will be greatly appreciated. (At this point, I also wish to consider alternatives to FFMPEG.)

Facts

I run FFMPEG from a script:

set srcFile=%1
set dstFile=%srcFile:.mov=.mp4%

ffmpeg -i %srcFile% -movflags faststart -q:a 0 -q:v 0 -pix_fmt yuv420p -sws_flags gauss -s 4096x4096 %dstFile%

Output

PS: Yes, for those who play at home, this is the 2001 theme - Space Odyssey. You can see the YouTube version 1K here: 2001 - Fuldyay’s Space Odyssey And yes, in a planetarium with a good sound system, this is absolutely EPIC.
