Re: Simple line doubling -- Possible?

I'm not very familiar with it, but I believe not at this time. Genuine question, what's your reference point for the 33% inflation? It's just a guesstimate based on my experience. Are you feeding HandBrake a line doubled copy of your source to test? No, I'm feeding the results of the encode back in...

Re: Simple line doubling -- Possible?

The effect is minimal and mostly prevents strong aliasing. The interpolation should not be required. It's simply blowing up the size of the encode by about 1/3rd. I guess you could output half height with custom anamorphic so your player would do the doubling, but most devices will do the same: som...

Re: Simple line doubling -- Possible?

Bob starts with line doubling, but is also interpolated for quality. Is there a way to solely do line doubling, only, and forego any interpolation? I think that foregoing interpolation would help with compression (and file size) without affecting quality. By the way, setting FPS to '120' didn't wor...

Re: Simple line doubling -- Possible?

It sounds like you want to disable interlacing detection ... So deinterlace is either always on or always off, right? ... enable deinterlacing with the bob or bob eedi2 setting ... Is bob line doubling? ... and set fps to same as source. That's close. Actually "same as source" produced twitter. Set...

How do I specify simple line-doubling (of 60 fields/sec) to produce 60 frames/sec? If you don't understand the frame & field specifications below, the question above should suffice.

Re: LPCM sorely needed

There's a lot of people whose old, premium audio gear doesn't take HDMI. There's close to a dozen companies making HDMI audio extractors to feed that old gear. They probably all use the same chip. They all seem to work with LPCM only. Users are buying them and returning them. Sad.

Description of problem or question: LPCM is not encoded, nor will it pass through. Therefore, audio doesn't work in homemade home theater system.

Re: Keyframe? -- What is meant?

It's format-dependent. H.264 has IDR-frames, H.265 adds a couple additional keyfeames types, if I am not mistaken. In older codecs, any I-frame is usually a keyframe, but it varies. Ah! IDR-frame: instantaneous decoding refresh, flushes the picture buffer. Okay. So I take it that "keyframe" is what...

Keyframe? -- What is meant?

General video question: I see the term "keyframe" used at various times. I know of only I- P- & B-frames. Is (perhaps) a so-called keyframe the 1st I-frame of a GOP? Or is the meaning of 'keyframe' left up to the author of an article to muck up? -- for example, the author of the Wikipedia page ( htt...

Re: Decomb Custom syntax

30i is 60p with each field being half of two consecutive frames in the 60p source. These frames are 1/60 second apart, thus the interlaced fields in 30i are 1/60 second apart. I am ...mystified. "30i is 60p"? "60p source"? i30 has p60 sources? "frames are 1/60 second apart"? I can't believe that wh...

Re: Decomb Custom syntax

Naturally, as interlacing depends on fields from two different points in time, interpolating these fields reconstructs neither exact point in time, but a combination of the two. Algorithms attempt various processing techniques to minimize any visual aberration, but none are perfect. Unless I'm miss...

The beauty of interlacing detection is where no combing artifacts are detected, the frame passes untouched, preserving resolution and sharpness that is typically diminished by any deinterlacing algorithm.
I fail to see how deinterlacing diminishes resolution. Can you elaborate?
