At my wits end with deinterlace problem

fatcharlie

I am having deinterlace problems with DVDFab, and I can't seem to figure it out, and I am close to considering asking for a refund or something.

I am trying to convert the TV show Tim and Eric Awesome Show Season 4.

My computer specs are as follows:
Compaq Presario CQ5300Y
Processor: AMD Sempron LE-1300
RAM: 2GB
Video: NVIDIA GeForce 6150SE nForce 430 (latest driver)
OS: Windows 7 64-bit
DVDFab: 8.0.7.3
Codec: K-lite (latest version)

DVD Specs:
SOURCE FILE TYPE: VOB
SOURCE VIDEO TYPE: ?
SOURCE VIDEO RESOLUTION: 640x480
SOURCE AUDIO TYPE: AC3
TIM_AND_ERIC_SEASON_4: Title(2), Play Time(00:11:24)
Original Frame Resolution (640 x 480)
Original Aspect Ratio (1.33:1)
Cropped Aspect Ratio (1.33:1)
Source Zoom: 61%
Output Zoom: 70%
Output Size: 640 x 480

The process I am performing is I do a DVD rip to my hard drive using DVD Copy, then I use DVD Ripper to convert to MP4, using the generic.mp4.h264.aac profile, with the standard conversion settings:
Fast encoding 1-pass
Fixed Bitrate checked (1381kbs)
Deinterlacing checked
Resolution @ 640x480

The final result has great quality but jagged edges whenever there is movement (top picture in attachment).

I decided to research the forums for this problem and followed the advice of this , and forced deinterlace on. At the same time I made four versions of the generic.mp4.h264.aac profile with the different possible deinterlace modes 0, 1, 2, 3.

Mode 0 had a little impact on the deinterlacing, while modes 1, 2, 3 did a better job. However the overall quality of the video went down with all four modes. I used the same standard conversion setting as the original generic.mp4.h264.aac profile.

In the attachment there are five pictures in a vertical row. The top picture represents the standard mp4 profile. Going down the pictures represent deinterlace forced on and the four different modes 0, 1, 2, 3.

I have had this problem with every DVD I have used, all TV shows.

Am I doing something wrong? Or is this as good as DVDFab can perform?

profiles I used:

PLEASE HELP!! THIS IS VERY FRUSTRATING!!!

Deinterlace "mode" should be set to "1" to force deinterlace regardless of other settings. Deinterlace method is what you should be testing to see which looks best. It is not clear from the text of your post which you are doing, the profiles look like you have tried the different method settings, which I think are bob,weave,blend etc. Remember that you can use the Title start/End settings button to make short tests rather than an entire movie or episode. Are these PAL or NTSC shows? I would also suggest that you test the original VOB files with MediaInfo (google it, free) and see what it says about the video. Also try different frame rates to see if that improves the output.

DVDFab has had glitches with the deinterlacing from time to time, but I though it was working OK. As you can see from the post you linked, the other users got it to work.

Thanks for the reply Signals. It did seem like modes 1, 2, & 3 helped the deinterlace but the overall quality went down, while using the exact same conversion settings.

Sorry for the small picture I wasn't sure on the attachment file size limits. How can I increase the quality of the conversion?

The best way I can describe the quality downgrade is if you look at the shoulder line or collar in the photo. With the standard profile the lines are pretty crisp and smooth. When I used the "forced deinterlace" profiles all the lines became jagged, regardless of movement. I can make more photos, in that scene in the lower left corner was a circular "news channel logo". It's very clear with that.

fatcharlie

I was changing the method, sorry about the confusion.

I downloaded mediainfo, but I don't see how that will help my problem.

Based on the post I referenced I will try DVDFab version 8.0.5.6 and see if that works. Otherwise I don't understand why forcing deinterlace on reduces the quality of the output.

You would want to run MediaInfo against one of the middle files. Find a VTS_0x_2.VOB file so that you are looking at the correct video part. The DVD authors often patch together some various video for the content warnings and intros. This is likely one of those problem DVDs where the video transitions from one type to another within the same title.

I assume that you are using "Same as Source" for the fps. You might try forcing the value. Unfortunately, without the MediaInfo on the correct file, I am unable to hazard a guess as to which fps you should try first.

fatcharlie

Thanks for the reply. I am still at a loss as to how the information from MediaInfo will help DVDFabs problem with deinterlace not working, and why the video quality goes down when I force deinterlace on.

signals

As Complication suggested, please try MediaInfo on one of the large VOB files--there should be a group of them that are around a gigabyte each, these are where the actual movie content is located. This will tell us what you are starting with and will suggest settings to try in the conversion.

fatcharlie

Ok, I will do that.

I did try a conversion with the bitrate increased to 5000kbs, up from 1836, with no change. Is it possible I may have to go higher than that?

signals

I don' t think so. Do the MediaInfo on one of the movie VOBs.

fatcharlie

First thing, as soon as I get home from work. :)

Should I also try changing formats? I arbitrarily chose mp4, though I did try mkv, but lost my sound.

fatcharlie

Ok, here is the information from MediaInfo. I did a DVD Copy of the first episode, so that explains the 11 minute duration.

I can see there is no reply yet. I have done a lot of experimentation on this and compared DVDFab's output with Nero Vision 10. There is no comparison, Nero is way much better. It uses motion adaptive deinterlace and gives a crisp clear picture even on fast motion. I suspect DVDfab is using a method which is the simplest and discards one of the 2 fields of the interlaced frame then fills in the missing lines by duplication. This gives an output which is half the vertical resolution and produces the lines on the progressive output. I now only use DVDfab to rip my DVD's to hard disk (Main Movie) and remove protection then use Nero to export to MP4 or AVI. Nero Multimedia Suite 10 only cost me Â£29.99 UK Pounds as an upgrade from version 7 which was supplied free with the Sony DVD RW drive I got for my computer. Unless the DVDFab team incorporate a decent motion adaptive deintelace filter, I won't use it. Another option is to keep the movie interlaced and not produce a progressive output. All TV's and most media players on PC's will display interlaced output ok. If the DVD playback looks ok (this is interlaced) on the PC then why deinterlace. But DVDFab won't even do this. Even if deinterlace is not selected it still produces a progresive output and looks awfull.

signals

Please try the v8.0.7.6 Beta, there were quite a few fixes related to deinterlace.

@chrisupyonder
Please read our rules and follow them. DVDFab supports several deinterlace methods.

Hi chrisupyonder,

Sorry for the trouble.

The DVDFab 8076 should fixed all deinterlacing problems, please try it to see the result.

We will provide more deinterlacing method options in future versions, including motion adaptive deinterlacing (very slow).

Best Regards,
Fengtao

I am also having deinterlace issues. For Season 3 and 4 of That 70's Show, it is like deinterlacing isn't even enabled (eventhough it is). The output still contains the interlacing. Any suggestions on how to solve this?

Start your own thread and include information from the Help Us Help You sticky thread including the log files. Make sure you are using an up-to-date version of DVDFab first.

Hi There
All you need to do is this -
Open up DvDFab
Select RIPPER and load the DvD you wish to rip
Go to Advanced Options (one of the 4 circle tools that appears) in this setting,
select DEINTERLACE, decide if you want the title split or not split and click OK.
You also have the option of keeping subtitles or not.
The DvD Ripper is easily the best and fastest option to Deinterlace, as it creates
an MP4 file from which you can either burn a dvd or archive to a hard drive.
