Re: Handbrake Deinterlace - What Really Happens

I've not been constraining my discussion to just Handbrake, but video theory in general. The fundamentals. If you can't see how it's relevant, then we're clearly talking different things. Haven't been to doom9 in a while, the forums seemed to slow down in the sections I was interested in lurking may...

Re: Handbrake Deinterlace - What Really Happens

musicvid, here's a little something you might want to read up on. The first paragraph in the "Background" section on this wiki I think offers a most succinct overview of everything we've been discussing here these past few days albeit talking about PAL video instead of NTSC. http://en.wiki...

Re: Upscaling 480P to 720P

And my one last post before calling it quits, i think your own example you've linked to proves one of my points quite succinctly. Three interlaced frames, each showing a capital 'A' in two distinct positions. Deinterlacing as you've demonstrated reduces that to just one position per frame when clean...

Re: Upscaling 480P to 720P

Well I was just gonna leave this be, but that example image you dug up is seriously flawed. It is clearly a photograph that was chopped up into fake "fields" just for some very rudimentary demonstration and fails to show the combing artifacts you'd see in an actual frame of interlaced vide...

Each field is a distinct image representing a 1/60th of a second timeslice of the subject video Jack, I already told you that is incorrect. And I'm trying to tell you that no, I'm the one correct on that point. What exactly do you think the difference IS between the two fields in a single frame? Wh...

Re: Upscaling 480P to 720P

No, deinterlacing 60i to 30p does not throw away half the temporal information. Sophisticated algorithms (Yadif, EED12, McDeint) use all the information from both fields to draw one progressive frame. You are describing primitive interpolation, which is obsolete. Best to know this before posting. Y...

Re: Upscaling 480P to 720P

SD was never shot or delivered for 60fps consumer playback, save for the brief appearance of EDTV (HDV-SD) about a decade ago. Until then, progressive frames did not exist above 320x240. NTSC video has temporal information at 60hz, that's 60 fields per second with 2 fields stored in each frame at 3...

Re: Upscaling 480P to 720P

I was disappointed myself when I saw youtube's new 60fps support is only for HD content, there's a lot of interlaced SD material out there that could benefit from being bobbed to 60p instead of destructively deinterlaced to 30.

Re: Automatic Cropping

If you create a custom preset with the cropping values all set to zero they will stay at zero when loading new files when using that preset, at least that's how it works in the Windows GUI, can't comment on the Mac or Linux versions but I assume they'd be the same. Also in the Windows GUI the croppi...

Re: How can I preserve interlacing, not deinterlace or stack

Going slightly of the topic. Has there been in thought about deinterlacing film content, by not deinterlacing the interlaced frames, by simply dropping the repeated fields/frames and restore it back to 24fps from the 30/25fps? I feel this would be a better approach, not only will it make a smaller ...

Well I'd be concerned. I've never seen that 70c max temp listed anywhere for FX parts but I HAVE seen 62c bandied about quite a bit within overclocking circles as a max temp for long-term usage with mid to low 50s a better target to ensure stability. Granted I've not actually looked at the spec shee...

Re: Are black bars encoded for every frame?

I vaguely remember seeing a series of encoding comparisons years ago between cropping and not cropping and the file size differences were negligible. I don't usually bother unless its pillarboxing on 4x3 content.

Those temps should be fine, the max core temp AMD rates their FX chips for extended use at is 62c so if you're in the 40s you're golden.

It sounds like the content on disc is in 4:3 and your TV is set to either zoom in or stretch the image to avoid showing 'pillar-box' black bars on the sides when it detects such content. Zooming in would cut off the top and bottom of the image, while stretching would distort the image making everyon...

Yes, those options will speed up encoding , at the cost of larger files. 20-25% larger is about right. That doesn't relate to your original question, which is about a decoding setting. Actually all of those options could impact decode performance, depending on the playback hardware in question. Cab...
