HandBrake

Discuss the HandBrake 1.1.1 Release here.

Hi,

Why no Win 32 bits version?

Regards,
Tompa

32bit support was dropped with 1.1.0. Three main reasons:

1. We haven't been testing the 32bit build for nearly 2 years now so the build was becoming less stable with time since we weren't fixing issues that only crop up under 32bit.
2. Memory limitations of 32bit builds are becoming more of an issue. Having large numbers of people complaining of crashes with 1080p and more so, 4K content isn't a good use of our time.
3. Every CPU that's above our minimum supported hardware is 64bit. The vast majority of our users are running 64bit OS as well. For those that arn't, 1.0.7 is still available on the old downloads page. It'll still work, there just isn't any support on offer for that.

Ah, i see.

Thank you anyway.

Why is there such a drastic change in performance after v1.0.7?

Performance of both the Windows GUI and CLI versions of v1.1.1 and v1.1.0 is abysmal compared to v1.0.7 and older on the exact same hardware, source material and transcoding parameters.

Summary results (average of forty-eight transcode sessions, twelve each for v1.0.7, v.1.1.0, v1.1.1 and ffmpeg 4.x on three hardware platforms):

- v1.0.7 is 3 times faster than both v1.1.0 and v1.1.1 transcoding 1280x720 content with and without using Intel QSV
- v1.0.7 is 3.8 times faster than both v1.1.0 and v1.1.1 transcoding 1920x1080 content with and without using Intel QSV
- transcoding with ffmpeg version N-90996-g29eb1c51d7 is 3.1 times faster than both v1.1.0 and v1.1.1 transcoding 1280x720 content
- transcoding with ffmpeg version N-90996-g29eb1c51d7 is 4 times faster than both v1.1.0 and v1.1.1 transcoding 1920x1080 content

Using twelve test MKV source files:
- three 1280x720 AC3 5.1 43 minute (avg) TV recordings,
- three 1920x1080 AC3 5.1 43 minute (avg) TV recordings,
- three 1280x720 AC3 5.1 107 minute (avg) movie recordings
- three 1920x1080 AC3 5.1 107 minute (avg) movie recordings

On three different Intel i7 quad core computers, two with 32 GB RAM and one with 16 GB RAM, all with Samsung PCIe x4 960 solid state primary drives and multiple Seagate 4 TB IronWolf Pro HDD storage drives running Windows 7 64-bit.

There are no significant performance differences between the two versions if you use the same settings / source / hardware.

Please start a thread in the relevant support forum, and post an activity log for before / after and we can point out the difference.
