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...

Re: Upscaling 480P to 720P
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 You are describing primitive interpolation, which is obsolete.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: No sound (H.264 + mp3 lame)
There are a lot of players out there, both hardware and software, that choke or just don't work as expected when presented with mp3 as the audio track in an mp4 video. It's just not a typical configuration. It works in something like VLC without issue because VLC is open source software designed to ...

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 ...

Re: Computer overheats while converting files
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...

I've been mulling over how best to rip Dark Shadows myself for a while. I never ran into this sort of problem on the few test encodes I ran, but that was ages ago. I suppose the simplest immediate solution (although more manually time consuming in setting up) would be to queue up and encode each cha...

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.

Re: New PC specs (in your opinion)
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. I imagine you've got that garbage stock heatsink that AMD supplies currently on there, if you're paranoid (or want to try a bit of overclocking at some point) then...

Re: DVD Encoding in4:3 Aspect Ratio
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...

FYI, VideoReDo TV Suite 4 does in fact support reading and writing MKV files. It's not as robust as their MP4 container support, but it's good enough for simple cutting and remuxing. Unfortunately it still probably won't do the job for you. Subtitle support is strictly teletext and closed captioning...

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...

That preset pack in step 3 might be out of date, the page states the tutorial was written for version 0.9.8 while version 0.9.9 is the latest stable release and even that's getting a bit old compared to the nightly builds. I would suggest ignoring that part, just try using the Normal or High presets...
