[Kevin Camp] “hey richie, it sounds like you figured a good workflow… but to expand on the rgb-yuv issue that i seemed to notice.

Thanks, yes I’m half there but I do need to look in to Yuv.

[Kevin Camp] “just converting the mpeg (yuv) to lossless animation (rgb) seemed to help significantly with the issue i saw in the original footage. apples’ uncompressed 8-bit and 10-bit are also yuv, so that might explain why you saw no difference. nle’s and players are probably better suited to using yuv media that ae is — though i don’t know why ae shouldn’t be as good, i do know that ae seems to be rooted in rgb.”

I wonder; maybe it’s not the deinterlacing in Virtualdub that’s helping, perhaps it’s the codec and simply rendering to avi? I’ll try a straght avi render and let AE do the deinterlace.

I agree with your statement bellow, infact the pixels don’t look like interlacing artifacts more like simple pixelation.

[Kevin Camp]
interlacing may or may not be the problem… the original file you posted was 24p, and didn’t seem to have any interlacing artifacts — at first i though the color issue was due to improper pulldown removal, but there were no interlacing issues in the luminance, just the brighter colors. also, just converting that file to an rgb codec fixed it, i didn’t try to deinterlace or remove the pulldown, just dropped it into a converter and exported to mov.

Was that in mpeg-streamclip? Squared 5? so you converted to the animation codec in this app as well, not in AE it’self?

Lol, btw Dave the other day I had to explain to someone why they were “out to lunch” they just stood there looking puzzled. . .

I know how you feel.

[Richie Tovell]

Cool, hey I think I’ve sussed it, it’s AE’s deinterlacing.

Thanks for your help Steve, at this stage I usually need serious amouts of moral support lol, but hey I fixed it. The first problem was the interlacing, the second problem is the colour, I’m not sure what causes the image to go so dark and flat but it seems pretty easy to correct, I fixed the deinterlacing in Virtualdub though, it’s a good app.

I even managed to get a decent 1080p render without much pixelation, bellow are some screen shots, it’s pretty close.

What stumped me was that when interpretting the footage in AE was forgetting to set the deinterlacing to “none” after I had already deinterlaced the clips in Virtualdub.

Thanks Steve.

I can’t record it of the screen, these screen recording apps just aren’t up to it.

The screen shots are acurate to hoq pdvd playback looks, it’s settings say it’s using native colour and resolution, so no tips there.

It’s a mystery how it upscales like that without any pixelation. I’d be happy if I could fix up the pixelated at 720 x 480.

[Richie Tovell]

Sure I realize that, I just dont want to add any more compression, and even uncompressed the file size is fine as it is.

I’m working with my comp res at full with a comp size thats the same as the footage 720 x 480, if you look at the clip in AE you can see the pixelation imediately, infact it already looks like it’s lost resolution so the first thing I did was check the comp resolution.

Ideally I would like to get the picture quality and upscaling shown in the screen shots above, however I’ve never had much success with plugins that upscale, they kind of work but I’d still be left with pixelation on the red areas.

What I might have to do is use screen recording software to grab power dvd’s playback, it’s a botchy way to do it but it may give the best results. Unless anyone can think of anything else? I really cant see how to get that picture quality.

Thanks for all chipping in you guy’s, I’m still nowhere near understanding this unfortunately. I had some luck using a Deinterlacing filter in Virtualdub, it completly removed all of the pixelation on the red colors, but added a substantial amount of blurring and also made the pixelation on the cars silver window a lot worse. I also tried converting to uncompressed mov, but it’s no different to the straight mpeg import.

I am intrigued to know just how these media players can make this footage look so good, bellow are three screenshots of the same file playing in Power dvd, pdvd has actually upscaled the output to 1080p, also notice there’s virtually no pixelation anywhere and the colours look amazing.

The problem I’m facing is that these vob rips make up %100 percent of my compositions, ok so this one is an extreme example because of the red, red and jpeg or Mpeg obviously isnt good, but what is power dvd doing that I’m not? I don’t understand.

If anyone has any more free time to spend on this I’d be more than grateful. I’d welcome any more suggestions, Kevin I’m still working through some of your ideas, I’m affraid you have me a little lost though, so I’m going to try some different conversion and ripping apps as well and just hope I can hit it. You guys should have a look at these png’s though as well, considering the source file, this is very impressive for a bundled dvd app imo.

Steve and Dave, thanks also.

From my experience the tinnitus will likely only occupy a single frequency, mine is somewhere around 10k, from this point of view you may be better off using a parametric eq as opposed to a notch filter.

Whilst I’m no expert on medical subjects my feelings about this article are mixed, certainly its worth trying anything however what you may end up doing is over sensitising the ear to the exact frequencies you want to treat, I’ll give you an example, if you were to listened to music that had 10k frequencies removed over an extended period of time, (half an hour or so) everything you hear afterwards would appear to contain more 10k than it actually does, this might actually increase the prominence of the tinnitus because your ears would be temporarily more sensitive to this frequency, these “ghost” frequencies are something I come across a lot when eq’ing for extended periods of time.

You can test this yourself quite easily, load a “good” quality piece of music in to your app, add a parametric eq, lower 10k as far as you can with a narrow as “Q” as possible, now listen to the track three or four times through, then remove the parametric and re listen, you will hear a sharp rise at 10k I guaranty.

I can demonstrate something similar using a short video, this is roughly the same thing happening with colour instead of sound

Well, I hope there is a cure found for Tinnitus soon, Personally it is unlikely that I will ever know the true sound of silence ever again, though as far as I know the human ear can recover (in time) however I’ve had mine for years. Incidentally one thing that did help me (a lot) was chucking out my old cathode ray tv, which was emitting a hi pitch tone at around 10k funnily enough.

Best of luck.

Richie.

One more thing I neglected to mention, all my files are 24 bit rendered from a 32 bit floating point, in addition to this I have the “Convert all audio files to 32 bit on import” check box ticked in my preferences this is making no difference, neither is “Convert file to. . 32 bit” function, my files are still being clipped to 0-db.

I’m really confused, it’s like Audition is deliberately converting everything to 16 bit, any ideas? This is very frustrating.

Ah, sorry, yes your expression does work fine, I was having problems but it seems this was caused by something else on the layer.

Sorry about that, thanks for the pointer though.

value +
L = thisLayer;
s = transform.scale.value;
while (L.hasParent){
L = L.parent;
for (i = 0; i < s.length; i++) s[i] *= 100/L.transform.scale.value[i] } s doesn't work, nor does this: L = thisLayer; s = transform.scale.value; while (L.hasParent){ L = L.parent; for (i = 0; i < s.length; i++) s[i] *= 100/L.transform.scale.value + [i] } s Any ideas?
