Intermittent motion blur

[pBS]

sounds like system instability, when removing/upgrading ccc, choose for it *not* to remove/upgrade system software[chipset drivers], just the video card's drivers..
but be sure to do a catalyst uninstall from control panel and reboot between installs..

i've tried 8.11 on everything from a lowly 9550 to hd3650's and all worked perfectly..
it may be because yours is an integrated chipset...they use slightly different drivers and installation a bit more tricky...
and each time you have to dl/install matching avivo codecs...

i would use 9.11 cat motherboard drivers, and try 8.11 video drivers..
but you're probably scared off of those..

and the tv deinterlacing thing i've never seen work...card still has to do work, and even more work since it has to make everything interlaced to send out to an interlaced display, but in practical sense, not much different..looks same..

i'm pretty sure you black screens are due to the chipset drivers, find a good one and stick with it..just play with the video drivers/avivo...

Yes, this is what I did. I think you are right about it being an "integrated chipset" issue. I am motivated again to install the new 4350 card, but I think you said there are no stable drivers for it...??

Anyway, I did a system restore followed by an installation of 9.12, which took me back to where I was yesterday. I have since discovered that using ffdshow as the h.264 decoder seems to be causing my video tearing. When I returned to CoreAVC, this went away; unfortunately, I can only use CoreAVC with MPV or Intervideo as the MPEG decoders, which takes me right back to the original problem (motion blurring due to poor deinterlacing). I wonder if there is another h.264 option out there?

Everyone's always talking about Cyberlink, but I can't seem to find it anywhere.

Talk to hoborg about the unlocked version of SAF - I think the cyberlink h264 decoder is in there.

Otherwise it's installing powerdvd (and I think not all versions allow their decoders to be used outside of the program anymore)
Also, why can you only use intervideo or MPV for mpeg when using CoreAVC?

can't you just disable the h264 codec in ffdshow?

I've been looking at the SAF...can you explain the "unlocking"?

I don't know why those two MPEG decoders don't work with that h.264 decoder...they just don't.

Good idea about disabling certain codecs. I am playing around with it now.

To unlock SAF, you need to send a PM to hoborg.

When I had a CRT TV, I got terrible tearing with my 4650 card when running at 720x576 which is the correct res for UK DVB-T recordings. I set it to 1024x576 and it was perfect.

I now use HDMI into a LCD TV, using SAF only and it looks mightly fine.

When watching a bit of snooker last week, I did detect a very slight micro-stutter when the ball was moving across the table. Definately not as smooth as watching the same show direct on the TV. I may be that the 200Hz motion compensation inside the tv is not enabled for the HDMI input, I've not found time to investigate further and typically, you would not notice it.

I really appreciate everyone's help, especially pBS who's given me a lot of good advice. Now that the "downgrade disaster" is out of the way, his ffdshow settings work beautifully--furthermore, even the slightest change messes everything up. I recommend the settings posted in this thread to anyone having the motion blur problems I was experiencing.

The only change I had to make was to use a different decoder for h.264. However, this may be causing other problems (see below).

Since pBS knows his codecs so well, I am hoping that he (or anyone) can help me with some issues this has introduced:

- video tearing from any progressive source. This is especially bad with WMV or MOV
- minor "jerking" every few seconds in HD video (the kind our wives wouldn't notice)
- the most serious problem: if I watch a recording while recording another, the recording adopts very serious artefacts. This include long pauses (up to two seconds) and large clusters of "missing" blocks. When I stop watching another source, the recording returns to normal. (This is a serious problem--so serious even my wife hates it!)

Any advice would be greatly appreciated.

I'm thinking the right Avivo encoder might help me with this. I have gone back to Catalyst 9.7 (most stable for me), but the encoder numbers don't always seem to match. How do I know which one to use? Are those of you using Catalyst 8.11 using the latest encoder package anyway?

What cpu useage are you getting while playing back a recording?
How defragged is your recordings HDD, and is it on another physical drive from your OS? (plus, is it running at the highest DMA mode available, and not PIO?)

Definitely sounds like your system choking when doing both at once. What type of recording (SD / HD, h264?)

I know what you're saying, and I'll check all these things, but it started happening overnight...the same night that I started using ffdshow codecs. before that, I was happily recording three things and watching another.

I have a separate hard drive for recordings. I defragged the system drive last week, which took 16 hours; given that the recordings drive is 200X its size, I don't think a defrag is viable. SD or HD didn't matter for the problem I was describing.

I want to go back to using the ATIMPEG decoder, but more strangeness: Last night it was working fine, and now I get no video in hidef. Edit: Ah, I get it, now. I was using TS Mux instead of DVR-MS. Setting it back to DVR-MS allows the ATIMPEG decoder to work as before, without ffdshow at all. It seems to be handing things a lot better, but not perfectly, when I am watching an HD video. However, it makes me a little bit sad because it is jerkier than ffdshow's decoders and because DVR-MS doesn't recover between shows when timeshifting (Sub put me onto that months ago).

BUT I'M STILL GETTING VIDEO TEARING ON PROGRESSIVE SOURCES! AUUGH!

Another edit: Oh, my, I don't believe this. I removed ffdshow completely, and that was the end of the video tearing. Why, I oughtta...

Yet another edit: But now, live HD doesn't work at all without it.

This is ridiculous. I give up. I am going back to MPV, and will just manually switch it from Bob to Weave.

How big was that drive? How fragmented. Thats a long time to reorganise files.

Why don't you run the MS defrag util and check how fragmented your recordings drive is? Maybe look at getting some type of idle time defrag utility as well.
Those recording drives get fragmented really quickly.
