About HandBrake

[sagor]

Hello everyone,
I have questions about HandBrake.

1.Is there any way to remove black bar from video without reduce the bitrate? (It's never exceed 20mbps for untouched bluray.)
2.Is there any way to possible remove black bar from lossy video without any compression?

The short answer is no, the black bar is part of the video image and must be cropped to be removed, whether you use Handbrake or not.

The best you can do is re-encode the video at high quality.

Sure, specify the same bitrate as your source when you re-encode.

2.Is there any way to possible remove black bar from lossy video without any compression?

You mean without any re-compression? No. To remove the black bars the video has to be decompressed, the black bars removed, then re-compressed. If you specify the same bitrate as the source you will get a file of the same size. If you use RF based encoding you will get a file of unknown size, ranging from much smaller than your source to much bigger than your source depending on the RF setting.

Though you could use a different tool like Avisynth or FFmpeg to crop the video and save uncompresssed or with lossless compression.

How?

How?

You don't want to know, as the lossless filesize will be many times greater than that of the source video. 10 times greater or more. Are you prepared for that? No, I didn't think so.

By reading the fine manuals.
If you want a GUI, VirtualDub can do it, too.

Yes, uncompressed 1920x800 (a 2.4:1 movie) YV12 runs about 250 Mb/s -- 10 times bigger than a typical Blu-ray source. Lossless compression will reduce that to about 100 Mb/s.

Handbrake can do this -- just use x264 and select RF=0.

I use legacy profile & RF=0.

But i did a test, taking a screenshot of the video and crop the black bar & size is remain same.
I don't know it's valid test or not.

I will give it a try.

More like 440 Mbps. (1920*800*12*24)

But seriously, stop mentioning "lossless" compression to newbies ... That's not what they want.

Of course. The player sees that your video isn't 16:9 and adds black bars to fill out your screen's 16:9 aspect ratio. In other words, that's the way the video is supposed to be displayed.
