    Um, pretty much what it says on the title. When I try to run a 16:9 640x478 mkv through Tx264 with 10-bit I keep getting this error

    ffms [info]: 640x478p 853:640 @ 24000/1001 fps (vfr)
    x264 [error]: height not divisible by 4 (640x478)
    x264 [error]: x264_encoder_open failed

    I'm just trying to lower the bitrate in 10-bit. Just plain x264 8 bits gets the same error and trying to crop or resize at the same time doesn't help. Cropping and resizing beforehand in something like Mediacoder also doesn't help.

    Is there a way to get around this or something involving the advanced options that I screwed up maybe? Note: I don't really know how the options in the quantisizer and partition tabs work.

    Any help would be greatly appreciated. Thank you!

  2. The problem is exactly what the error message says: 478 isn't evenly divisible by 4. The codec requires mod4 frame dimensions. Use 480 or 476.
