x264 - can't open mbtree stats file

[Colek]

Hello,

First pass goes through smootly, but when it comes to second one I am getting errors as follows:

ratecontrol_init: can't open mbtree stats file
x264_encoder_open failed

Here's my .bat file.

x264.exe --pass 1 --bitrate 22000 --bluray-compat --level 4.1 --preset ultrafast  --tune film --keyint 24 --sar 1:1 --slices 4 --vbv-bufsize 30000 --vbv-maxrate 40000 --b-pyramid none --weightp 0 --colorprim bt709 --transfer bt709 --colormatrix bt709 --merange 24 --stats ".stats" --output NUL "AVS.avs"

x264.exe --pass 2 --bitrate 22000 --bluray-compat --level 4.1 --preset slow  --tune film --keyint 24 --sar 1:1 --slices 4 --vbv-bufsize 30000 --vbv-maxrate 40000 --b-pyramid none --weightp 0 --colorprim bt709 --transfer bt709 --colormatrix bt709 --merange 24 --stats ".stats" --output "FINAL.264" "AVS.avs"

Preset ultrafast does not use mbtree thus does not create an mbtree stats file. Use identical preset for all passes.
