Can handbrake deinterlace with same frame rate as field rate?

Post by wgf_bean » Thu Oct 18, 2018 8:39 pm

We all know that with interlaced video there are odd and even fields. Each field only has information for half the image.

From my testing of the output of Handbrake the deinterlacer appears to combine fields as follows:

frame 1 = field 1 + field 2
frame 2 = field 3 + field 4
frame 3 = field 5 + field 6
etc.
This results in a frame rate that is half the field rate.

However this is not how hardware deinterlacing works. Hardware deinterlacing does this:

frame 1 = field 1 + field 2
frame 2 = field 2 + field 3
frame 3 = field 3 + field 4
frame 2 = field 4 + field 5
frame 3 = field 5 + field 6
etc.
This results in a frame rate the same as the field rate.

Interlaced video was originally developed to maintain the higher frame rate at 1/2 the bandwidth. Having frame 2 be derived from fields 3 and 4, rather than 2 and 3 violates the intended purpose of interlaced video.

Is there a deinterlace setting to keep the frame rate the same as the field rate so there's a new and unique frame with each new field?

I've tried forcing the output frame rate to be correct but that just makes each frame get repeated once, which is pointless.

The version of handbrake I'm running is a nightly from:
HandBrake-20180912-09ed0b5_x86_64-Win_GUI.exe

Hardware deinterlacers work in a variety of ways just as software deinterlacers do. Not all hardware deinterlacers produce double rate output.

What you are looking for is the "bob" preset in either the decomb or deinterlace filters.

Thanks. When I use "bob" preset in either I get a frame rate that's half the field rate. The deinterlacing itself works great. Just not the correct frame rate. For example with an input file from broadcast television mpeg-2 1080i, the rate becomes 29.97 rather than 59.94. For sports broadcast, 29.97 doesn't look right.

Am I missing another setting?

No idea. An activity log would likely provide the information we need to diagnose. See the red box at the top of the page.

I created a small test file - only about 3 seconds of video. Here's the log file for it: https://we.tl/t-sVvEZI3UJZ

I also did some reading on FFMPEG. It has a filter option -vf yadif=1. If I perform this it gives the desired result:

Code: Select all

ffmpeg -i "R:\Temp8\test3.mkv" -vf yadif=1 -c:v libx265 -crf 28 "I:\Handbrake\output3.mkv" -hide_banner
From the FFMPEG documentation...

Code: Select all

10.207 yadif
Deinterlace the input video ("yadif" means "yet another deinterlacing filter").

It accepts the following parameters:

mode
The interlacing mode to adopt. It accepts one of the following values:

0, send_frame
Output one frame for each frame.

1, send_field
Output one frame for each field.

2, send_frame_nospatial
Like send_frame, but it skips the spatial interlacing check.

3, send_field_nospatial
Like send_field, but it skips the spatial interlacing check.
It appears Handbrake uses yadif mode=0 (Output one frame for each frame).
I need yadif mode=1 (Output one frame for each field)

How do I get Handbrake to do yadif=1?

So, according to your log, you used the decomb filter, but did not use the "bob" preset.

ffmpeg options are not the same as HandBrake options.

Are you wanting to use the CLI or the GUI? If GUI, simply select the bob preset on either the decomb or deinterlace filter. If the CLI, "HandBrakeCLI --help" and read the documentation for the decomb and deinterlace filters. They both list the bob preset and how to specify it on the command line.

I prefer to use Handbrake. I only used FFMPEG to confirm the library can do what I'm looking for.

So I processed again explicitly selecting Deinterlace: "Decomb" Preset "Bob"

The result is still not the desired output.

Here's the log file:

I've tried many combinations but they all result in output files with a frame rate of 29.97 rather than 59.94.
I can force the output to 59.94 but then the output simple repeats frames rather than having unique ones. Deinterlacing is working fine. The output frame rate is what I'm having an issue with.

I realize the interface to the FFMPEG library Handbrake uses is different than the command line interface, but I thought the functions are fundamentally the same.

Re: Can handbrake deinterlace with same frame rate as field rate?

Post by JohnAStebbins » Mon Oct 22, 2018 9:19 pm

Code: Select all

[16:24:49]      + Framerate Shaper (mode=1)
[16:24:49]        + frame rate: 29.970 fps -> constant 29.970 fps
You selected a specific constant framerate that is not the framerate that you say that you want. It did exactly what you asked for.
On the video tab, either leave the framerate set to variable, or set it to the framerate you actually desire.

Re: Can handbrake deinterlace with same frame rate as field rate?

Post by wgf_bean » Mon Oct 22, 2018 9:52 pm

I processed again selecting Deinterlace: "Decomb" Preset "Bob", and output frame rate 59.94

The output did create the correct number of frames per second, but the output frame data was not correct.

As I playback the output stepping one frame at a time the motion reverses direction every other frame, as if the filter is selecting the wrong fields when creating the output frames.

Here's the log file:

So I tried again selecting Deinterlace: "Yadif" Preset: "Bob", and output frame rate 59.94
This created an output with every other frame repeated, and also not properly deinterlaced.
Here's the log file for this test:

Re: Can handbrake deinterlace with same frame rate as field rate?

Post by JohnAStebbins » Mon Oct 22, 2018 10:20 pm

Why are you enabling the detelecine filter? That may be the cause of some of this behaviour. The detelecine filter can lock to false telecine patterns in interlaced input and produce odd results. Try disabling this first, then see the rest of my comments since this could be skewing the results.

If disabling detelecine doesn't improve things and the motion reversal problem persists, your content either signals the wrong field parity or it doesn't signal it at all and HandBrake's default doesn't match.

You can set the parity manually by using custom decomb settings (select custom in decomb's preset option and you'll get a text entry box to enter the custom option. E.g. "mode=23:parity=0" is the same as bob with Top Field First parity. Try parity=1 for Bottom Field First.

You can do the same with yadif, but the custom settings would be "mode=7:parity=0".

Re: Can handbrake deinterlace with same frame rate as field rate?

I had set the Detelecine to Default, assuming it would chose the correct option. So I changed that to Off and now it works! The output is now as expected - smooth with no motion reversals, and a unique frame at 59.94 Hz.

As a summary to anyone else trying to get the output frame rate to match the field rate for interlaced TV content:

Detelecine: Off
Deinterlace: Decomb Preset:Bob
Then set the video output frame rate to double the input frame rate. (since the input field rate is double the input frame rate)

Thank you JohnAStebbins, you're my hero!

Glad you got it working. I should have noticed that earlier, would have saved us both a little time :mrgreen:
