it’s jus because it doesn’t support 1080p24…I see judders on every video, while I don’t see any on my pc…
Your PC supports 1080p24 display natively? Not likely. Unless you’ve spent a lot of money on specialized video cards and monitors, you don’t have a PC that supports 24p native playback.
MOST monitors today cannot display that slowly, and only a few support perfect multiples of 24Hz. MOST are at 60Hz (or very close to it), which means that your PC has to do the exact same 2:3 telecining that a media player does at 1080p60 to get it to display without “Screen Tearing.”
At least in Win7, you can verify this by clicking the background, then Personalize, then click DISPLAY, CHANGE DISPLAY SETTINGS, ADVANCED SETTINGS, then the MONITOR tab… Mine says 60Hz.
So, what I’m getting at is that if you DON’T see artifacts on your PC but you DO see them on the EP, it is NOT Telecine JUDDER you’re seeing, meaning it’s not a result of it not supporting 1080p24.
JUDDER is a VERY SPECIFIC artifact. Just because you see motion that isn’t smooth, it doesn’t mean you’re experiencing JUDDER.
We need to be VERY specific here, otherwise you could be chasing wild geese. Because if it IS judder you’re seeing, there’s nothing we can do to fix it. But I don’t think it is Judder you’re seeing.
I just managed to get my hands on a 1TB EP for some testing. I can tell you without a doubt that all of my 1080p24 material plays JUST FINE on the EP. My rip of my Avatar BD plays beautifully on my 55" LG LCD when set to 1080p60. There MAY be judder there, because it is doing Telecine, but I can tell you that it’s extremely mild (I can’t even notice it when I’m looking for it, and it certainly doesn’t jump out at me)
I tried a whole slew of test files. I DID start to get some Motion Breakdown when total bitrates exceeded about 40 Mbps (which is actually pretty impressive). All of these files are 1080p23.976 fps material.
This is a group of test files at specific bandwidths.
ie, bird20.mkv is at approx. 20mbit per second.
103,989,696 bird38.mkv 108,638,208 bird38.m2ts
--mkv mild breakdown--- --- m2ts still good ---
114,918,832 bird42.mkv 120,041,472 bird42.m2ts
--mkv moderate bkdown-- --- m2ts still good ---
140,559,134 bird50.mkv 146,817,024 bird50.m2ts
153,521,171 bird55.mkv 160,333,824 bird55.m2ts
--mkv bad beyond this-- --- m2ts still good ---
167,019,983 bird60.mkv 174,422,016 bird60.m2ts
193,822,181 bird70.mkv 202,389,504 bird70.m2ts
--- m2ts bad beyond ---
219,299,090 bird80.mkv 228,974,592 bird80.m2ts
242,133,511 bird90.mkv 252,801,024 bird90.m2ts
These test files have NO AUDIO tracks. Just video. I’m actually impressed that M2TS went up to 70 megabits per second without noticable motion breakdown! But MKV started suffering as early as 42 megabits per second. Now, if you start adding multipe audio tracks to these files, the bandwidth starts going down real quick.
