![]() "The spike is predicated on disruptions in supply meeting this big demand and those tend to happen in very sudden moments and will work themselves through. ![]() Upside potential may have already been exhausted, Sanchez said. "They were big negative earners during the pandemic and so as the economy reopened and energy demand started to pick up, naturally that was going to be a boon for all energy companies." "Energy had a long way to catch up," Sanchez told CNBC's " Trading Nation" on Tuesday, explaining its big move this year. I'd be glad if anybody knew a filter for Vegas or VirtualDub using this technique.But, it may be too late for investors looking to buy in on more upside, according to Gina Sanchez, chief market strategist at Lido Advisors. Finally Cyberlink released version 6.0 of their PowerDVD player including an adaptive deinterlacer so now the most prominent players are on the same level." The first builts of WinDVD 6 Platinum included the same chroma bug as the predecessor but recent builts have apparently solved the issue. However their adaptive deinterlacer could be confused by complex video material. The company Ahead from Karlsbad in Germany included their DVD-player Nero ShowTime into their CD/DVD-burning suite Nero 6. Next was the chinese player Blaze-DVD 6.0 - with the same chroma error. However they incorporated a severe chroma error which resulted in colored shadow-images. InterVideo was first with WinDVD 5 Platinum. ![]() In the meantime more and more manufacturers are implementing adaptive deinterlacers to their DVD-player-software. A more complex adaptive deinterlacer will search up to 5 fields in both directions. Frame 3 from fields 2, 3 and 4 and so on. However they anolyze only the adjacent fields. A good adaptive deinterlacer is capable of producing perfectly sharp progressive pictures at the original framerate.Ĭurrent video chips of ATI and NVIDIA already use adaptive deinterlacing internally. Areas without counterpart are interpolated. If patterns are recognised those contents are moved into the current picture. Pixel by pixel the content of the current field is compared to the preceding and following fields. Therefor the decoder has to account for not only the information of the current field but also of the adjacent fields. "However there is a way to improve the quality of deinterlacing. However the resolution is effectively halfened.Īdaptive Deinterlacing (aka Progressive in WinDVD) Good deinterlacers use up to 6 lines for the interpolation. Here the missing lines of each field are interpolated from the content of adjacent lines. So every picture has to be shown twice in order to compensate.īOB (both "blend fields" and "interpolate fields" in Vegas 5 are implementations of BOB algorithms) Furthermore the frame rate is effectively halfened. However as soon as there is motion you will see those infamous mice teeth. As long as the scene is static this works quite well. The two fields of a frame are just displayed at the same time. Weave is not really a deinterlacing process. Just for clarification here's a translation of the description of the most common deinterlacing methods as found in the c't-special "DigitalVideo" 01/05 (c't is THE most competent german magazine on computers): Theodore Walling Posts: 528 Joined: Sat 6:48 am With DVD software playing back the interlaced avi files, it looks great though. In any case, I've never minded interlaced video playback on a TV. When I play the original interlaced avi files with PowerDVD, it looks as good or better than it does on a TV. When I deinterlace with Vegas/DVFilm/VirtualDub the footage looks blocky and the motion is no longer smooth. When I use media player, I can see those nasty interlace artifacts that we all complain about. I've started using PowerDVD instead of Media Player to view DV files on my PC. Whatever it's doing, it looks pretty darned good. ![]() In other words instead of showing 30 interlaced frames a second it dropping fields and doubling lines 60 times a second, so that in essence, what you're seeing is 60 fps progressive footage (albiet at half the vertical resolution). I think what is going on is that PowerDVD is doing a bob type deinterlace on regular 60i. I've been reading up a little since making this post.
