Help - Authoring Giving Me Horizontal Lines On TV?

[daishan]

Ok, I capped a VHS movie to AVI (MJPEG) and converted it to MPEG2 with Canopus Procoder.

At each stage...AVI & MPEG2...the video plays back just fine on my computer.

Now I author it with TMPGEnc DVD Author and burn it. The resulting playback on TV gives me interlace-like horizontal lines here and there whenever the camera moves. It's really annoying.

Now I read up on this a little bit and I have some ideas, but would like some experienced insight if possible.

Is my problem not picking 3:2 Pulldown filter in Procoder when I converted the AVI to MPEG2? Because the AVI was marked as Non-Interlaced, while the target MPEG2 file had Upper/Top Field First.

Or should I have left it alone but changed the target's interlace setting to Lower/Bottom Field First instead of Upper/Top Field First?

Either way I have days worth of FUBAR'd video. So what I'm looking for is a solution to prevent future encoding from being screwed up......as well as a solution for my already encoded MPEG2 files which I'd rather not have to redo!

Thanks for any help

Authoring can't give you horizonal lines only encoding.

If your source is interlaced you should set the source to interlaced and output to interlace. Try both lower and upper field.

Your problem sounds more like wrong field order.

Ok, it's definitely not the field order. I changed it from Upper first to Bottom first and I still get the same damned lines during any sort of quick motion on the TV.

I used DVD-Lab to demux, ReStream to change the field order, and TMPGEnc Plus to remux.

The only thing I can think of now is my not choosing Video Pulldown in the Video Filter area of Procoder during the AVI to MPEG2 conversion.

Is there any way to do Video Pulldown directly to the MPEG2 file in another program? I'd rather not have to re-encode all of what I've already done.

Also, does anyone have any further ideas to fix the problem?

You need to encode from the source file again. Set both source and destination to interlaced format. If source is top field first also set destination top field first and vice versa. You can try it with a short sample of the clip (you can set start and stop in procoder) and burn to a DVD-RW first to see if it looks fine before encoding the complete file.

I had problems with few files. I tried changing field order (in TMPGEnc) but it didn't help. There are also tricks on these forums for to find out the field order with TMPGEnc or AVISynth. Neither did any good; the result was the same. I ended up deinterlacing the avi with VirtualDub and the enconding it to non-interlace MPG with good results.

Ok, everything's solved, but still I wonder why I couldn't do a interlaced one

I see what you're saying. When I did it initially and put the Source AVI/MJPEG file into Procoder, it automatically detected it as Non-Interlace.

Then when I picked the Target as DVD-NTSC, it automatically picked Top Field First.

What you're saying is I should've changed the Source's setting to Top Field First as well before I went ahead with the MPEG-2 conversion?

Or am I not understanding you?

I'll try this anyway, because nothing is working. I demux'd the thing and swapped Top Field to Bottom Field and remux'd and didn't work.

I tried to re-encode the demux'd files with the 3:2 Pulldown, no change.

I even went back to Top Field and re-encoded the demux'd files with 3:2 pulldown to no effect.

And I KNOW making it Non-Interlaced won't work on my TV.....so this is my last hope here I think.

Unless you are talking about capturing the AVI all over again, but interlaced instead of non-interlaced. If that's the case then I'm lost. No idea how to make that happen with iuVCR.

Anyway...I'm off to re-encode

jsut a point on Procorder --- it doesnt automatically pick field order .. it just appears to pick one or the other and seems to get it right about 50% of the time ....

then you run across mpeg files encoded in CCE -- they will always be marked top field first no mater what the original source was .. so when you go and re-encode them for some reason .............

Well I fixed my problem and thanks to Ronnylov for the statement above that fixed it.

When I imported the AVI to Procoder it automatically said "Non-Interlace". Then I just picked an interlaced choice for the Target. Upper and/or Bottom didn't work for crap. 3:2 pulldown added to either mix didn't do crap either.

The solution? Importing the AVI to Procoder and changing it to Upper Field and choosing Upper Field for the Target as well. That was it!

I don't know if choosing Bottom Field for both would work to, but either way should be a solution for anyone with this problem in the future.

Now, back to preserving the original Star Wars trilogy....cause we all know Han shot first damnit!!
