Re: Deinterlace options

Bob extracts the 60fps information out of an interlaced source. Making the final output a 60fps progressive output.

Re: Preserving Dr Who Decomb BOB when combining handbrake rips and other files!

When using bob, you are making a progressive 60fps (50fps PAL) video out of the interlaced material. It is no longer interlaced and still gives the similar look of old tv smoothness.

Re: ATV3 / PS3 Chapters - making them work for both

As far as I know, the PS3 does not read the chapter tags on mpeg4 files. At least it never has for me.

Re: Dolby PL II surround center channel issue

As for this issue, I believe it mostly happens when there is a strong correlation between the left and right surround channels. We decided to not revert to how liba52 and libdca do their downmixes because while it happens to alleviate this issue, it's technically incorrect. What is more correct? My...

Re: Dolby PL II surround center channel issue

I think the issue you found is indirectly realted. Ran the original MKV with the 5.1 DTS (also had the problem with files that used Dolby digital as well) through MplayerX, and its mix down to stereo exhibited the exact same issue with the center surround shifted to the right with the main center pl...

Dolby PL II surround center channel issue

Ive noticed in the recent version of handbrake, because my older encodes do not have this issue, that when converting a 5.1 source to DPLII that surround "center" gets moved to the right channel when there is a main center channel sound playing. Its like the matrix surround is not encoding properly ...

Re: Small files off DVD are huge and the large files are small ?

Handbrakes default settings are designed to adjust bit rate based off image complexity to get the best compression and image quality. So a video with nothing moving much will get less data given to it, as it doesn't need much data to compress the little amount of changes per frame. Videos with a lot...

Re: Upscaling 480P to 720P

In a normal movie, one can hardly see the difference between 30fps and 60fps. It's realy useful on video games with strict timing like 2D fighting games. Not true, you can easily see the difference between 60FPS and 30FPS. Watch sports or the news on broadcast TV (60FPS), and then watch a sitcom ( ...

Re: Bob vs. Decomb -- The HD tests

I don't know if handbrakes bob filter does yadif correction like the default decomb method. (could any handbrake developer clear this up?) If not, the single frame results would defiantly be sharper on the 30P video. Other programs can do bob with yadif, or other words ,bob + weave deinterlacing. Al...

Musicvid, I have a question for you. What is shadow noise? I know you mentioned it in our last forum but couldn't see what you were talking about.
I do expect bobbing 480i to show a lower quality still image as its output is essentially 720x240 output. 1080i is 1920x540 bobbed

Re: Handbrake Deinterlace - What Really Happens

I just realized that you missunderstand what a bob filter does. It is not interpolation where frames are created out of thin air like the "soap opera" effect that some hdtvs can do. Bobing literally pulls the frames out of each field and reassembles them into a 60p. To keep the motion information to...

Re: Handbrake Deinterlace - What Really Happens

I consider any loss in a video a bad thing. I find temporal loss to be the greater of 2 losses. Dropping every other potential frame is a severe loss. Unfortunately, making 30i into 60p is not the best quality vs a real 60p source, but sometimes that's the only source available and SDtvs are quickly...

Re: Handbrake Deinterlace - What Really Happens

I wouldn't worry about the quality. I didn't exactly use the highest quality setting on my capture device or even tell handbrake to do higher quality for 60FPS. I just used that footage to show 60FPS taken from a 30i source. Handbrakes bob filter is a dumb bob filter as far as I know. I doesn't try ...

Re: Handbrake Deinterlace - What Really Happens

You should use decomb bob and not deinterlace bob. Deinterlace will output only what it's given. Decombing bob will output 60fps if it needs it, Saving resolution on still images in the video. Remember still items in interlaced video are full resolution. bobbing the telecine video will produce lesse...

Let me give you my definition of extract. To pull out of or to separate from a source. Like extracting audio from a movie. Yup. It has to exist first. Otherwise you are extracting air.

I agree with your scaled-back claim, with the exception once again of the word "extract," which implies something that cannot actually be done.

The misunderstanding was not that we misunderstood how handbrake deinterlaces, but the claim that interlaced video contains 60FPS of information.
