Full 50 fields/sec display on PC

[zpunout]

I accidently came across a codec which enabled my PC to show interlaced MPEG2 and SVCD at the full 50 fields/sec, not the juddery 25 frames/sec that most MPEG2 codecs do.

Only problem is I reinstalled Windows XP with a new hard disk and i cant watch my MPEG2 in its full 50 fields/sec glory anymore, just 25 frames/sec instead.

I used Windows Media Player to watch the files on all occasions.

I suspected the codec came from WinDVD 4 last time but now it doesn't work to its full potential anymore assuming it was an Intervideo codec.

To understand these de-interlace methods it is good to checkout a free tv card decoder software called DScaler if you have a tv card.
Any solutions?

What would you like to do.

Not "Bob" or "Weave"

Does anyone know which codec (or filter) can properly display my interlaced mpeg2/svcd files in the full 50 (or 60) fields per second.
Rather than the usual blending the 2 fields together per frame such as conventional "Bob" and "Weave" techniques.



Also, if i had more than one type of codec installed to play one type of video format, is there a way to choose which codec decodes the video for me in Windows Media Player?

[decryptit]

have you tried xvid

[zpunout]

I will try Xvid and report back, though Xvid appears to be all about Mpeg4 in source code format.

Does it have relevance to watching Mpeg2/SVCD and/or deinterlacing methods?

Progressive De-interlace

I downloaded a demo of WinDVD 5 Platinum and discovered it has what they call "progressive de-interlace".

They have the right idea. They discuss it in the WinDVD5 help file as follows:
"Progressive - Progressive deinterlace is the current state-of-the-art video technology, capable of converting 60 interlaced fields into 60 progressive frames, doubling the video data rate for smoother DVD playback. The Progressive feature is only available with the Platinum version of WinDVD."

Only problem now is that it is incorrectly displaying which field comes first resulting in jittering motion. (my source material is B-bottom field first). Intervideo needs an option to choose which field comes first.

Perhaps a commercial interlaced DVD disc has material that is recorded with the field settings set to "A-Upper field first"

I do know that for my DV home videos (in SVCD format) to play correctly on a stand-alone DVD player (so the motion is not jittery) i need to set my MPEG2 encoder (which is TMPG Enc) to encode the file with the field order set to "B-bottom field first"

I want my video files to display correctly on my PC !!

Does anyone know what i am talking about?

do you have ffdshow

Wow, decryptit, what a useless git you are. your posts are almost pointless. How unhelpful.

[decryptit]

i'm asking important questions that you haven't dared to ask so shut up or else assit this person with eighter asking him or answering him with suitable questions.

[Jomo]

Uhh.. Someone is having problems with A/b fields and interlacing, and your asking him if hes tried xvid, lol your asking random questions to get your post higher. sad man..

1) Quote:
"I accidently came across a codec''

Duh ,I have just suggested since there is no information given
about his codec i reccomended him with a staight forward one like xvid.

2). Quote:

"Does anyone know which codec" (or filter) can properly display my interlaced mpeg2/svcd files in the full 50 (or 60) fields per second.

3)I told him if he has tried Xvid.

4)He answered:
I will try Xvid and report back, though Xvid appears to be all about Mpeg4 in source code format.

HE STILL CLAIMS THAT HAS TO TRY XVID THERFORE THIS MIGHT ALSO HELP IN GETTING RID OF HIS PROBLEM.

If you think you are of help in here you are completly wrong just
f*** my way and if you think you are capable of offering some help just do it and don't comment on other people's attidues.

hahaha!

Thats all you can post.

Ive been looking at the direct show filters that came with xvid and ffdshow.

There does seem to be some post-processing options when i look up their properties in Graphedit, but when i test them i have difficulty building a combination of filters that work together without the program hanging when i perform a seek or stop command on the Mpeg2 file.

When they do play, it seems to be deinterlacing the old way anyway. But, this might be from other filters interfering with how the video is post-processed.

Can anyone tell me if they have had success from using filters from xvid of ffdshow themselves?
If so, which combination of "de-multiplex -> video decoder -> post-processor -> full screen renderer" was used?


PS . Yep WinDVD 5 only accepts "upper A field first" video properly!
Those videos play sooooo nice and smoooooth!

Wondering what Graphedit is? View this link:

Yes they may interfere.What filters do you have installed besides
ffdshow.
