Intermittent motion blur

[keith_leitch]

I don't know. I tried the ATIMPEG decoder (which I assume is the Avivo recorder that PbS referred to above) and got a black screen as usual. I've tried it again in the last five minutes and it works...sort of.

Quality is passable in both SD and HD. However, it won't handle any progressive (720p) broadcasts, giving a very jerky result.

Is there anything out there that just works for everything? I have a feeling ffdshow is the answer, but I can't get the settings balanced for all the different types of video. Alternatively, how do I make the Cyberlink decoder available? Will installing PowerDVD do it?

ahh,you need newer version then...get the ffdshow tryouts beta6...
it's the best one,very stable and works on every card brand i've tried..
with mpeg2, there can be a mix between progressive and interlaced content, and if the decoder can't read the flags and tell when to do deinterlacing, and when not to, it'll look bad on one content type or the other..
[progressive stuff needs weave, or really no deinterlacing, and interlaced stufff needs deinterlacing..]
beta6 is the first one that reads the flags and deinterlaces appropriately..
leading to a picture that looks exactly like a live tv feed...
avivo should do same, all versions..maybe not in vista+ tho..
so sounds maybe like buggy driver or bad install of them...

what version catalyst are you using?
i would clear out the driver completely and try cat. 9.11...then try 9.9 if that doesn't work right..then 9.6
not that many good ones to choose from cuz it's so new..

to get a similar but still not proper deinterlaced image with mpv, i uncheck first checkbox about colorspaces, then check second about deinterlacing, third your prefeerence..
leave deinterlacing set to auto, tho it should be greyed out..
that should yeild decent results...but still not as good as it'll get..
maybe cuz that's a new chipset, need latest drivers, or they may not work properly yet..
[i had to wait a year for them to get 3xxx's driver right...but when it's right, you know it...]

Thanks for all your help. The situation is improving. You were right about ATIMPEG. It is now giving me the best overall result, although it is NOT handling progressive stations automatically; lots of video tearing and blurring that makes me think it is trying to deinterlace them. It looks best with 576i and 1080i, but MPV (with your settings) is a better balance. (By the way, I have no idea why I could not get ATIMPEG to speak to me before when it is working reasonably well now).

I appear to be using Catalyst 9.8. I will update it if I absolutely have to, but I am sick of doing so as it always screws something up. I will await your advice.

You were also right about ffdshow. I now have the version released on 14-12-09. Do you think this is the release of your Beta version? If not, where can I get yours?

FFMPEG has solved a few problems. It is now detecting and deinterlacing MPEG, DVR-MS and TS Mux automatically. It seems to be struggling with MOV and WMV, though; I am getting deinterlacing lines and video tears. Since I am decoding MPEG2 with something else, I can probably just set some fixed deinterlacing protocols; I will try that now.

Other problems are that I'm still playing some FLV files double-speed, and others without sound (a problem I've been trying to solve for a year).

Also, any tricks I try (deblurring, NR, etc.) just make the video stagger to unwatchability. This implies to me that I am stressing my CPU. The GPU option using Avivo is therefore more attractive in many ways.

Do you believe that the ATIMPEG decoder is the Avivo decoder you are talking about?

maybe cuz that's a new chipset, need latest drivers, or they may not work properly yet..

Actually, it's an X1200 (rather old), onboard the ASUS M2A-VM. I have an HD4350, but I had some trouble disabling the onboard video when I tried to install it, so I gave up. Do you think I should persist?

[pBS]

yea, i would...it'll do way better than the x1200...[which is really underpowered, but should definitely do mpeg2 fine with 8.11 catalyst...no h264 accell at all..but ffdshow h264 should work ok on it...

trust me, 8.11 cat is best for all pre 4xxx cards...i thought you had hd4200..[another post]
for the 4350 use 9.11 [latest]

the ffdshow version is critical for success...
use the 'download' now button on right, that's good version beta 6..

and don't use any deinterlacing from ffdshow...it'll get the video card to do it..

OK, thanks. I'll wait until I can give myself some time, and change cards. I will check in back here at that time.

I should list my specs in a signature like you do. What an industry.

actually i'm having problems getting a good 4xxx driver working...
i know that 8.11 rocks out of the box for earlier cards, but doesn't have the 4xxx cards in it or i'd use that..

try 8.11 on the 1200 first...probably easiest solution...

Hmmm...interesting. I could always forego CCC altogether and use the new card.

I've been thinking, though, that I am making this too difficult. Why deinterlace at all when my TV supports 1080i? If I just take off all scaling values and interlacing codecs and let the thing speak to the TV "natively," won't I be bypassing all these difficulties?

Of course, the progressive sources would become interlaced. I'm not too concerned about that now, but I would want a better solution before I go Blu-Ray.

If anyone out there with an ATI card has a problem with your monitor going blank when you change resolutions, I recommend against downgrading the Catalyst driver. The problem I mean would be similar to the one described in this thread:

http://forums.nextpvr.com/showthread.php?t=44721

I've had lots of advice, not just here, that 8.11 is more compatible with my X1250 graphics card. I'm sure that is true, but it has made this problem much worse: video now blanks on virtually every change of resolution.

Once I fight my way through this I will try upgrading back to the latest version (9.12).

[keith_leitch]

Boy, I mean it, everyone. Do not roll back your Catalyst driver unless you are VERY sure that it will help you.

Aside from the problems above, my video has never looked worse, even using the same codecs and renderers; it is jerky and blurry and filled with video tears. In addition, the ATI MPEG decoder (the one that worked best before I did this) does not seem to be included. This was all after a day of manual driver installs and restarts to try to coax the thing onto my system to begin with.

Just...don't...do...it.

I am actually trying now to see if I can bail myself out of this with a system restore before I upgrade to 9.12.
