How to handle mpeg2 movies flagged wrong (interlaced <--> progressive)

[mkanet]

I'm recording Comcast cable TV. It looks like there's some content that that's incorrectly flagged when playing it back via cyberlink pdvd 8 mpeg2 video decoder.

I'm curious what easiest options I have to watch these recordings correctly.

For example:

1- Could configure my pdvd video decoder (directshow NOT CYBERLINK PLAYER) to try different deinterlacing menthods that dont depend on flags? I know these options are available for the PowerDVD player itself. However, I dont know how to change these options of for the direct show filter only.

2- A very simple software that can read the flag attribute of a video clip and allow me to change it. I'm not sure if this can be done without re-encoding (which i dont want to do at all).

Thanks!

Thanks I just tried it. Just a quick question. If "Frametype progressive" & "Progressive sequence" aren't selected when a video is loaded, is it presumed the material is "flagged" as interlaced? Do only these options need to be selected for the video to be "flagged" as progressive?

Perhaps there's a forum better suited for specific question for Restream?

You don't want to set the Progressive sequence flag. Yes, if the Frametype progressive box is unchecked in ReStream, it's been flagged as Interlaced. Without some proof, in the form of a small sample, I would doubt it's been flagged incorrectly.

Manono, thanks for the helpful response.

Below, I have two TV recordings loaded into ReStream. Both recordings are supposed to be standard ATSC HDTV 1080i, but when I play them with my hardware accelerated mpeg2 decoder, I see skipping in the video and interlace artifacts during big scene changes (combing). All the other TV shows that are ATSC HDTV 1080i decode very nicely, just some specific shows and movies.

I am curious if you see something that is VERY wrong with these settings to cause the decoder to have problems. Is there a way to have a hardware accelerated mpeg2 decoder (ie, PowerDVD 8 mpeg2 video decoder + Nvidia 8800GT) have settings to better tolerate these kinds of videos that dont deinterlace properly?

I can upload these clips if that would help.

PS: I dont see the problem when I disable Hardware Motion Compensation in the mpeg2 decoder (using software only).

Go ahead and upload sample clips. That's usually the quickest way to get a definitive answer.

Here's one clip... it definitely doesnt play correctly on my setup. Maybe you can find something in the flags that would cause it to playback incorrectly.

It shows interlacing because it's constantly switching back and forth between Interlaced and Progressive encoding. Players usually need a few frames to pick up on changes like that. It shows interlacing periodically when I play it as well. I think your best bet is to run it through ReStream and make the whole thing interlaced. Don't ask me how, though, because I don't cap and couldn't even get a decent M2V back out of it. Maybe you know how, and I'm sure others around here know how. If it were I, though, I'd IVTC and then reencode it to make the whole thing progressive 23.976fps.

It's a peculiar one, for sure. I don't cap, as I said, so I don't know how common that sort of thing is.

[mkanet]

Thanks. Well, I do need to find a better solution than reencoding anything; as I get these types of files all the time. I was hoping to find an mpeg2 filter that just plays it back correctly using hardware acceleration. Thanks for you time though.

It's 3:2 pulldown using a combination of hard and soft pulldown. I've seen a few of these lately. I would expect such streams to thoroughly confuse some players. I doubt that you can fix this by changing interlaced/progressive flagging.

It's very common for real-time HD MPEG-2 encoders to fall in and out of inverse telecine. Here's a command line utility to dump the telecine flags of MPEG-2 video elementary streams:

For example, here's the dump from a portion of mkanet's file.

Im curious, what specifically could cause for my decoder to have "jumpy video", for example, during a big slow panning scene; or, anything big in general than pans across the screen. Also, when a scene changes to a completely different scene (simple to complex scene), there's a flash of interlace combing artifacts.

Why would 1080i "video" based content (as opposed to "film") render perfectly, or 1080i ATSC standard mpeg2 (please look at the specs for ATSC) video playback perfectly. What's different about the one you downloaded compared to these?

Thanks so much, I really appreciate it.

It's 3:2 pulldown using a combination of hard and soft pulldown. I've seen a few of these lately. I would expect such streams to thoroughly confuse some players. I doubt that you can fix this by changing interlaced/progressive flagging.

Below video is only 12MB's and is a perfect example of jump video and flashes of deinterlace combing artifacts. It's happening once every 3 seconds. Maybe there's some flags in the video that might have you a hint to whats wrong.

Thanks!

Below video... Um, where is it?

If your player can't play streams properly, get a new player that can!

Oops :) Sorry, here's the link:

It's not the player. Its the hardware acceleration it depends on. It doesnt matter what mpeg2 decoder/player I use. If I turn off hardware acceleration, the interlace problems go away, but the picture is softer and less detailed. I haven't found an all software decoder thats anywhere near as good as Nvidia's (when Nvidia actually works). I thought it might be my nvidia card, but it doesnt have any problems at all on much more demanding scenes on standard streams (ie, ATSC compliant).

There's nothing wrong with the streams. They are fully MPEG-2 compliant.

I just found out what's wrong. It was my display adapter (8800GT). I swapped it out with my old Nvidia 8600GT, and it played everything back using the same decoders, same driver (and driver settings). I dont know how the card got damaged specifically that way without affecting anything else.
