"problems" playing on DVD standlone player

[rubog]

Hi,
I transcoded from MJPEG to mpeg2 using a "VIDAC Movie+" card , a family movie for one of my friends.This friend has standalone dvd player (UMAX ) and a FAST capture card, which capture from a VCR in MJPEG.I use a Morgan multimedia software decoder in order to decrypt what he has capture from the analog video source.
After I transcoded the MJPEG movie into mpeg2 movie I burned a DVD.The dvd plays very well on the computer but in the DVD player the image is not ok : in the movements are not smooth.They "jump" a little.
The setting I used to do the transcoding are :
- MJPEG Morgan decoder (decompression settings) : "Support interleave" checked and "Invert field order " checked.
-my cards settings : I applied 2 filters(1-st for de-interlacing and 2-nd for resizing to DVD standards) .The resulted MPEG2 file was interlace type (there is another option to set on my card parameters).
Why the movements are not smooth ? I believe I "respected the techniques" .I did something wrong ? Or the mjpeg codec is not fully compatible with the MJPEG hardware codec of my friend (it's a Zoran chipset on that card).
I expect any opinion and any question about this problem.
I must say that what I described above it's only one of my tries.I did more tests about this problem setting in all kind of ways the parameters described above.
Thank you to anyone for any help

Why did you invert the field order? Getting the field order wrong can cause your video to 'jump'. It's most visible on wide panning shots. Make sure you encode a small test clip before any big project, to ensure your settings are correct. I would leave the field setting alone. The only reason you would typically change this setting is if your encoder has a problem with the field order the video comes with.

Deinterlacing can also cause a jerky appearance. The video may not actually be jerking, but you end up seeing two different frames combined into one (depends on the type of deinterlacing you use), cauing the same visual effect.

I would leave the video interlaced. Your television is designed to display interlaced signals. By deinterlacing, you only degrade the quality of your video. Most PC DVD software will also deinterlace your video on the fly during playback. If you intend to play this video on a PC, see if your playback quality is acceptable with your test clip (ensure you use a Software DVD player..Windows Media Player is not a good choice). If the quality is acceptable, then leaving the video interlaced is the best solution.

I think it's a field problem also. I (was) using ATI MMC 7.5 and was having trouble capturing Interlaced. My files would play great on computer but would jump (like yours) on TV. If I captured Deinterlaced I didn't have this problem. Come to find out this was, I believe, Field Reversal. I updated my VIA motherboard drivers, Windows VIA drivers, ATI MMC to V8.6, Sound Card drivers, and everything else I could find and my problem has since went away. My Interlaced video looks like it's supposed to now.

I agree, you shouldn't of Reversed the fields nor used Deinterlace.

Just my 2cents worth.
Good Luck

Hi,
thanks guys for your advices.I agree with you.Should work if I'm not changing the field order and leave it interlace .I'm not sure I try this settings because few days a go I did a lot of tries.But today I will do a try with this settings and I hope will be ok.Thanks again and I'll give a feedback soon.

Again me with same problem
I tried the method you said : interleave settings for MJPEG software codec and no deinterlace for my capture card software.On computer looks great ,but on dvd player ... when is some movement on the screen all the image starts to tremble.Ignoring this huge trembling the movements of the people ,cars etc looks smooth and are ok. If I interleave the original video file and after this I applied a de-interlace filter then ,on dvd player , the image is stable .Only when are large movements of the camera(a big part of the image has changed) ,then can be seen that the movements are "done in steps" and not smoothly.Only he "little" movements (small parts of the image are changed) are smooth.
Any explanation ? I ask again this because the first 2 answers seems very logical,and however....

It still sounds like field order. What software are you using to encode?

[rubog]

I use hardware capture card ,Vidac Movie+.But the field order can be set by the MJPEG software decoder (the source is a MJPEG video file coded with a FAST capture card).
If I remember well (I did a lot of tests....) I did test with both possibilities : the "Invert field order" checked and not checked.Last time was with this box unchecked ( = leave same field order as the original?? )

[DJRumpy]

I think I see where the problem may lie. By reversing the field order, I meant while encoding to MPEG, not during capture. I would leave the field order 'as is' during capture. No reason to change it. Make sure you try switching the field order in your encoder.

What software are you using to encode?
