![]() ![]() Versions 2.6.x display them, but won't let me use the cursor. SOME of my videos, though recent, can only be scrolled with 2.5.6. * Including the old 2.5.6 v° (32-bit, but as long as it works.), most recent one that belongs to the "2.5.x branch" (as opposed to the "2.6.x branch" very similar interface but quite different softwares in fact). several versions * - and, when one refuses to work or returns its (quite usual) "too short" warning, switch to another v°. The right side is further sharpened as described." AviDemux", besides being excellent, is full of bugs (nevertheless, I couldn't live without it). I just checked the script I used for the side-by-side video - the left side is deinteralaced with QTGMC and denoised with SMDegrain(). You may not even need to sharpen in post. You'll get much better results that way - more detail, less noise, and sharper picture. Use a DVD recorder with a line time base corrector to clean the video (don't record to DVD, don't apply any other filters, just pass the signal through the recorder for time base correction) and capture uncompessed YUY2 of YV12 video on the computer. You should go back to the original Video8 tapes if you still have them. Regarding your Video8 to VHS to DVD process: it's terrible. Overlay() was used to replace the areas that were not sharp in the original video with the sharpened video. A sharpened version of the video was created with UnSharpMask(). to build a mask of all the sharp edges in the source. ![]() SMDegrain() was used to reduce a lot of the noise (because the later sharpening would greatly increase it) I was aiming at shapening the blurry portions of the picture while avoiding oversharpening the already sharp parts. Overlay(UnsharpMask(2.0, 2.0), last, mask=emask) QTGMC() was used first to deinterlace the video. SMDegrain (tr=9, thSAD=500, refinemotion=false, contrasharp=false, PreFilter=4, mode=0, truemotion=true, plane=4, chroma=true)Įmask = mt_edge(mode="prewitt", thy1=100, thy2=250).mt_expand().mt_expand().mt_expand().mt_expand().mt_expand().Blur(1.4) Overlay(last, edges.Invert().ColorYUV(off_y=-128), mode="Subtract")ĬolorYUV(off_u=-1, off_v=-1) #overlay is causing U and V to increase by 1 Overlay(v, edges.ColorYUV(off_y=-128), mode="Add") The downside is that not all the tape might require the same script but it might still be worth trying if you are up to the task (or some kind person might volunteer and do it all for you) Hi,įunction UnSharpMask(clip v, float radius, float strength)īlurry = v.BinomialBlur(VarY=radius, VarC=radius, Y=3, U=3, V=3) # or GaussianBlurĮdges = Subtract(v, blurry).ColorYUV(off_y=2).ColorYUV(cont_y=(int(strength*radius*256.0)-256.0)) But if you can master it then you can create the video yourself without the need of another transfer. The harder bit is collecting the various filters and, typically, many of these also rely on other filters to work. I am sure that jagabo will share his script with you. The script is then read by another program typically virtualdub which creates a new video. In this case unsharpen, noise reduction and deinterlacing. Very different beasts.Īvisynth works by reading a script created for the selection of filters most suited for the job in hand. He used a tool called avisynth - I am just now wondering whether you meant this and not avidemux. Allow me to contribute as to how jagabo worked his magic. Now I'm at cross-road but there is no urgency. In the later case where can I find the instrument. But also I'm considering whether to do it myself. Now I'm considering whether sending another VHS tape or V8 tape to another shop ripping it to DVD. Afterwards I play the DVD on DVD writer of my PC and found some video being blurry, not clear. It was more than 20 years ago.Ībout one month ago I sent a VHS tape to a shop providing service ripping VHS tape on DVD. The video was quite clear and without problem when being played on X-ray tube TV. Afterwards I transferred the video from V8 tapes to VHS tapes myself. Surely there are firms even by mail in your country that do this work ? I captured video with Sony V8 Video Camera. The original Video8 would give you the best picture but did you not say that was broken by the shop ? Another sign of a poor service.īut whatever you have really does need a new cleaner transfer. Just Video8 to DVD or Video8 to VHS to DVD. ![]()
