No, this is the first time I tried to encode 4k material.
I had been always using HM11, it didn't work for 4K encode settings.
I haven't tried any other versions. comment:4 Changed 11 years ago by davidf
The usual cause of crashes with 4K is running out of memory. Please confirm if this is the case (usually indicated by an attempted null pointer dereference after an allocation). comment:5 Changed 11 years ago by xinjun
Okay, I could do more tests to figure out where it crashes.
Moreover, whether I ran two jobs at the same time, or I ran one job only, the crash took place at the same frame.
Perhaps I should build 64-bit application? comment:6 Changed 11 years ago by davidf
If you have not built a 64-bit binary, the process is limited in the size of the virtual address space it can access (depending upon system, that can typically be between 2 GiB and some amount less than 4 GiB¹).
You will need to build a 64-bit binary in order to avoid this.
From experience, coding 4k is unlikely to work using HM using a 32-bit process.
¹ NB, on windows may be controlled to some extend at link time using the /LARGEADDRESSAWARE linker option. comment:7 Changed 11 years ago by xinjun
I will try to build 64-bit application and report back. thanks comment:8 Changed 11 years ago by xinjun
Confirmed that 64-bit application successfully encodes beyond a few frames.
Please close this issue, and perhaps a sentence or two can be added in software manual against 32-bit applications. comment:9 Changed 11 years ago by davidf
