after conversion to mpeg2 gets interlaced

[forare]

hello

I am using powerdirector to convert dv avi into mpeg2 (720x480, 8000bitrate) but it is always interlaced
especially on fast camera motion , i replaced vga card and got a 256 MB nvidia but still having same problem

how to fix it ??

thanks for any help

That file has been blend deinterlaced.

DV format is 720x480i/29.97fps interlaced so that is what you want. Set your editor to 480i and encode 480i MPeg2 for TV. The TV will handle deinterlace if necessary. If you don't want interlace for computer playback, use a deinertlacing player like VLC or PowerDVD.

Yes it has, but it could be the player he was using to take the pic that did it. It could still be interlaced. And if so, I agree with you that it's the way it should remain. If it was really blend deinterlaced somewhere along the line, that's the last thing he should want, and he should start over and do it right this time.

[edDV]

VLC also has a good frame capture mode. See "Snapshot" under "Video". Snapshot follows the deinterlace settings. No deinterlace is called "Disable".

no matter how i play it using windows media player or power dvd or on my dvd box it is always like the picture above , is there any mpeg2 codec will prevent deinterlace while encoding ? i thing the codec within my software is causing this

[manono]

Both of those players may be deinterlacing it. To be sure of how it was really encoded, open the video in VDubMod and scroll around. Or go into your players' configure or preferences and check to see if all deinterlace is turned off.

In my old PowerDVD, I right-click the screen and go Configuration->Video->Advanced->Video Mode->Force Weave. If it's interlaced, you'll see the lines. If it's blend deinterlaced, it'll look all blurry. You can pause it and advance a frame at a time to have a closer look. I can't help with WMP as I refuse to use it.

If you really did deinterlace it, it's nothing to do with a codec, but some setting you applied, intentionally or not, in your encoder.

[edDV]

I found an old PowerDVD3. This has a DV format input and my settings are "High Quality DVD"

The resulting file was 720x480i interlace as expected.





Here it is played with VLC also GSpot details.



PS: I'm going to repeat with the "scan source clips and set field order" checked.

[forare]

I loaded mpeg2 file in Gspot and found it uses main concept and ulead decoder i deleted both and endocded again but exactly the same result appeared again
but i encoded same file using premiere pro 2 as deinterlaced and upper field first and it worked fine i got a good result but this did not solve the problem because i still need to work on power dierctor instead of permiere
i wonder if there is any tool to re encoed or repair the inerlaced mpeg2 ?

I ran out of time last night. Got too late (after 1AM here). There may be a field reversal going on. DV is BFF, the output MPeg2 file is TFF. Most programs allow a setting for a BFF/TFF for the encoder. This one doesn't. It just has that auto detect check mark that didn't seem to do anything.

Next I was going to load a non film based action file to see what is happening. I may not get to it tonight. Have project due tomorrow.

[forare]

I spent so many hours trying to encode using premiere 2
with so many options. I used either interlace or de interlace with upper
or lower field first or non progressive but the result is blurred footage
on fast camera motion.
I think i ran out of option and i believe many codecs are installed which messed my system up
so i will format the system and work on it all over again
will post feedback
thanks for the help anyhow

[edDV]

Sorry, I had a project loaded and couldn't get back to this.

For Premiere Pro you should use these settings for a Dv project. Start with the DVD 4:3 High quality preset in the MPeg2 encoder settings.

720x480, 29.970fps, Interlaced Bottom Field First
For bitrate start with 8,200,000 bps VBR

If there's a lot of camcorder motion (handheld) and if audio is set to MPeg, you can bump bitrate up to 9,000,000 or more with CBR.

Now there will be interlace line separation during motion if you view this on a progressive computer monitor as straight playback. It should be showing line splits like this, not double imaging like in your original file.



If you feed the DV video back to the camcorder and then connect to your TV from the camcorder, or play the resulting DVD to the TV in 480i mode you won't see line separation at the TV.

A VLC BOB deinterlace on playback looks like this on the computer monitor
(using VLC Snapshot to grab the frame).

[edDV]

I ran the same clip through PowerDVD3 and got a similar result.
I forgot to set 4:3 in the clips above.

[edDV]

Here is the 4x3 MPeg2 out of the Mainconcept encoder to compare with Power DVD3. They look similar.
Screencap again is VLC Snapshot with deinterlace off.


and the VLC Bob deinterlace during playback

yes same here i am able to deinterlace in the power dvd and get a good play result but the problem when burning to dvd and playing on stand alone dvd box it is still interlaced but even worth as they mentioned it is blend deinterlace which i have no rememdy yet i am not able to figure out a way to encode from dv to mpeg2 without getting a blurry interlaced footage.

It is possible the blend is happening in your DVD player or TV.

Is your DVD player set for 480i out?
What is your TV Model number?

Is this happening just with one file or with any DV source file?

I have tried on several dvds and 2 tvs and tried all possible settings
the problem is within the encoded mpeg2 file itself always interlaced on any fast camera motion
and from any dv avi source file

It should look just like a direct camcorder playback on the TV.

What model DVD player and TV?

[forare]

ok here goes again

i formatted my pc and installed only premiere pro 2 only
encoded a dv into exported dvd using default settings in premiere
here is the result even worse

This is driving me crazy i am thinking to buy a new system

please any ideas on what is causing this ? thanks a lot


only on fast camera movement as before






I checked the codecs in Gspot and i got this

[manono]

Small samples of both the source and the output would be helpful. 5-10 seconds of each uploaded somewhere so we could have a look.

This is driving me crazy i am thinking to buy a new system

It's nothing to do with your system. It's nothing to do with the codecs you have installed. Formatting was a complete waste of time. It has to do (most likely) with how you're encoding these videos. If you can't seem to master Premiere, maybe it's time to take a look at a different encoder for your projects.

only on fast camera movement as before

I kind of doubt that. The whole thing was deinterlaced (and screwed up in the process), but the worst effects are visible only during movement.

You know this is happening not only in permiere . I have tried powerdirector and ulead dvd movie factory
and all are giving same output. I guess this is something with my codecs however i have not installed any.
anyway i will upload the original and the encoded footage when i get home, but still looking for correct settings to for the encoded mpeg2 ??any ideas
thanks

[manono]

If you're asking if I know how to encode DV video, then if the encoder is CCE, HCEnc, and probably Procoder, yes. edDV probably knows the correct settings for the encoders you use, and has already given them to you for Premiere Pro, but you keep blaming it on things that have no bearing at all. Heck, even the title of this thread is completely off the mark. Based on the pics you've provided, after conversion your stuff is deinterlaced, not interlaced.

[edDV]

I'd like a sample of the source file. If all encoders get the same result, this points to a problem with the source. Are you certain this is a pure camera original DV file that was captured over IEEE-1394?

Also what is the model number of the camcorder that generated the file?

Ok here is a sample file (original dv)
http://www.mytempdir.com/2033153
i am using a Sony minidv trv-19 and yes i am using firewire to copy to HD as dv avi

and here is the encoded vob using default settings in premiere pro 2 (interlace, 720x480i, cbr 7000, bottom..)
http://www.mytempdir.com/2033208

i tried Progressive and lower field first but still same result

Had you bothered to do that 2 weeks ago, you might have saved yourself a lot of anguish and time. Here's an untouched frame from your encoded VOB:

encodedvob.png

So, I guess your frames were being deinterlaced by your players.

[edDV]

As mentioned above, VLC makes a good player and frame capture reference so we can compare. Intelace playback uses the "disable" setting under deinterlace. Your player must be blend deinterlacing.

[forare]

in other words is the encoded vob done correctly? so when i play on dvd box the quality is too bad but when playing a movie i bought quality is excellent so there is a gap here i cannot figure out

i did use vlc and the file is interlaced but i check deinterlace and i still get terrible quality on fast motion so what is still missing ?
thank you

[manono]

Yeah, the encoded VOB looked OK to me. I couldn't find any sign that it had been improperly resized or anything else that might prevent it from playing normally on a standalone DVD player.

You had been showing us pics of it deinterlaced. My default MPC also blend deinterlaces. That's why I had suggested opening it in VDubMod, which shows you the unprocessed raw source. As soon as you do that, you see the interlacing. As near as I can tell, it's been encoded properly, and I can see no reason it won't play OK in a standalone DVD player.

so when i play on dvd box the quality is too bad but when playing a movie i bought quality is excellent so there is a gap here i cannot figure out

There's a big difference between a DVD made from DV and a retail DVD of a Hollywood movie shot on film. The 2 will have a completely different "look" from each other. One is video and the other is film. One is made by an amateur and the other by the best professionals in the business. But I don't know what you're seeing on the standalone, so there may be other reasons for the differences as well, I don't know.

[forare]

dear manono
did you try to play my vob in vlc ? set it to deinterlace and you will see
like a double edge all over . This is ecxactly how i see it on my standalone,
I played it on onother box and excatly the same so i think my player is not deinterlacing something else is wrong

[MysticE]

For what it's worth I ran both files through ConvertXtoDVD. Ticking 'De-interlace (Recommended for DV sources)' produced clean results.
