De-interlacing method

Yeah, that is what the review said - that the card will try to attempt vector adaptive deinterlacing but cannot maintain realtime playback. That's unfortunate, because vector adaptive deinterlacing is a quality approach (uses optical flow analysis to interpolate position of features between the two fields).

It's a snarly process - but - you can split the MVC into left and right uncompressed streams (AVI uncompressed) using Peter Wimmer's MVC to AVI converter. Then, use AVISynth & YAFID to deinterlace the streams and re-compress in AVI container (in VC-1 or H.264 format) @ a target bitrate that your system can handle for realtime playback (e.g. 10 Mbps).

One major bummer of the TD10 - is no 24P.... and if you deinterlace into 1080 60P, 50P, 30P or even 25P, you cannot play using most HDMI 1.4a 3DTVs.

Thanks, i don't need the MVC converter, because Vegas handle the raw video.
If the TD10 can record 24p in 3D, i doubt how often use it.
24p to my eyes is just not enough in 3D.
I really like stedicam moves, aerial footages etc in at 50/60 fps in 3D.

Anyway i try to play back my TD10 files with another computer, this time with
an Ati 5450 card. It also support weave, bob, vector adaptive deinterlace, but
none of them work good with Stereoscopic player. Motion was never smooth.
It was like 25p again. :(
Even the 5450 cannot to this? I can't believe. My i7 cpu can solve the whole problem,
but i cannot set software deinterlace with the player??

Prech,

What are you viewing your output from Vegas on? Do you have a Black magic card or something similar?

3D BD spec states:

1920×1080 @ 23.976 fps progressive
1280×720 @ 59.94 fps progressive
1280×720 @ 50 fps progressive

I use a TD10 - and although the limit of raster size is 1280x720, results for motion are excellent. I simply create a project in 720 50P.

No, i mean i don't need a separate program for converting to AVI, etc,
because Vegas handle TD10 files, and i can render out avis, mpeg2 files from Vegas.

Prech, the TD10 does not record 23.98 in 3D mode, only in 2D mode. One of your earlier posts seemed to indicate you were unsure about this.

It's really annoying because the Sony literature obscures this fact and I didn't find out until I had shot it as a C camera for 8 days and then saw the readout in Inspector. No harm, Twixtor fixed the usable shots.

Paul:
i like to view my TD10 3D footage on my fullhd Cinema3D display, without resolution loss,
and with smooth playback. Why not, if it's already in 50i format?
I like to quick check and playback the footage from Stereosopic player with good deinterlacer,
and don't want to convert to 720p only for viewing it. For this task geforce 210 and even ati
5450 is weak? That was my question. If yes, what is the minimum card for it?

Sorry Bruce, my english is not very good. I know that this cam cannot record 24p in 3D.

"If the TD10 can record 24p in 3D" is not exactly what i want to say.
Instead: "If the TD10 could record in 24p".. With a new firmware or something.
In this case, i doubt i will ever use this mode, because i don't like 24p especially in 3D.
I can slow down my 50i footage to 24p, and we also have a dual projector setup with
50Hz refresh, so when projecting the video, 50i is very good!

That's great for personal viewing - but - for distribution, it's a downfall. 3D Blu-ray is limited to 24P in 1080 and HDMI 1.4a's manditory mode for full-frame 1080 is 24P too.

[Prech Marton]

Yes, and i can slowdown my 50i footage to 24p nicely.

Still searching the cheapest vga card, which can playback my
TD10 50i files with Stereoscopic player at nice 50fps.
Do i have to use ON- OFF or AUTOMATIC in settings/format/deinterlace?

I also installed the latest coreavc, but it doesn't work (player says: codec necessary)
Seems it can use only the internal coreavc mvc codec, but without hardware acceleration by me.

I recently bought a PNY GeForce GT 430 1024MB for $62.24 with shipping on Amazon.com. It has great motion-adaptive deinterlacing with Stereoscopic player (NOTE: I've only tested with TD10 60i content, not 50i). I leave the Stereoscopic player deinterlace setting at automatic.

I think the CoreAVC (MVC) decoder (or an OEM subset of it) is built-in to Stereoscopic player.

Thanks.
If you can test with my 50i file, would be great.

Yes, the coreavc is built in the player, i just installed the latest one, hope
it helps, but does not.

Yadiff is very good but I have been experimenting with QTGMC which is considered by many to be the best. It is an avisynth filter but realy does need the multi-threaded version of avisynth. It's speed can be configured depending on the quality you need.

[Prech Marton]

David: have you tested with my 50i file?
I can now buy a 220 card for cheap.
Should i buy or not? :o

[David M. Cole]

Ooops... sorry... dropped the ball on that one. I just verified that your 50i test file de-interlaces perfectly on an Nvidia GT 540M GPU. Looks great - no tearing.

Best,

David

[Prech Marton]

So you see 50fps not just 25?

* news: i became an info from Peter, the author of the player.
He wrote when deinterlacing is enabled, the player drops
one field, resulting in 25p, no matter what hardware you use.

So how can you see good deinterlace?
