640 X 480 AVI to SVCD interlace or Deinterlace? JERKY MOVEME

[snoopycml]

What are the Best settings for Converting 640 X 480 MJPEG AVI created with the Pinnacle DC30 into SVCD with TMPGenc 12H?

Do I keep Everything interlaced, or should I deinterlace?

I have tried everything: Switching field order (A and B) selecting interleced and noninterlaced, and no matter what settings I use I still have ghosting or jerky movement on my computer AND ON MY TV. I am using High Quality Motion Estimation, and the NTSC SVCD Template, and I have tried modifying it every possible way... Should I use Virtual Dub's filters, and just frame server?

I have heard that 2 out of every 5 frames are interlaced, and the rest are not, is this true? Does anyone have a template they like or a fool-proof method for converting 640 X 480 (possibly interlaced) AVI into smooth good quality MPEG-2? I don't care what it looks like on my computer just as long it is smooth and perfect on my TV.

is your AVI choppy? you might be dropping frames on capture. when in doubt, just deinterlace it, or use Even ONLY or Odd ONLY. it's a different problem depending on if the jerkiness goes away by throwing away one field.

What are you capturing? (IE: Is it a home movie, TV show, commercial film?) And at what frame rate, 24 fps, 25 fps, 30 fps, or perhaps even 29.97 fps.

I'm suspicious that you might have captured 625-line video using 525-line settings. If you're in Europe or Australia, you have 625-line PAL video, so you'll need to capture at 640x576 instead of 640x480. If this is the case, it'll cause a great deal of grief.

The "2 frames out of 5 are interlaced" rule could apply if you live in a country with 30 fps NTSC video, like the USA. Technically, all TV frames are interlaced, but when a 24 fps movie film is converted to 30 fps, 2 out of every 5 frames are interlaced together from mismatched film frames, so the capture actually "looks" interlaced. The other 3 out of 5 frames are interlaced too, but nobody calls them "interlaced" because they don't look that way.

If source truly is interlaced and target is TV, I would keep the interlace for smoother playback on tv. if you want to play it on computer deinterlace it.

I am capturing a Video that is 29.97 FPS NTSC. I am 100% sure it did not drop any frames. I will try throwing away one whole field.. I have been blending both fields... maybe that is my problem... I would love to keep everything interlaced... in fact I have tried that... but it is still jerky. Does anyone know how to keep the Video EXACTLY how it is when it is AVI? I do not really want to deinterlace.. just to keep it exactly the same and play back the same... does anyone have a template they like to use for TMPGenc? Thanks for all your help everyone I hope I can figure this problem out.

I have been capturing VHS video with a setting of 704x576 25 frames/sec PAL using AVI_IO, 24bit input and the PIC MJPEG Codec with the ASUS 7700 Deluxe card. I have set the codec not to use the 2 field setting but it seems that it sometimes does it anyway. When looking at the captured avi it sometimes looks great without any traces of interlacing and sometimes not. There are no dropped frames.

When encoding to SVCD (480x576) I usually end up deinterlacing the video and set TMPGENC not to interlace the end SVCD MPEG. The results are sometimes a bit jerky and shadowing in the scenes with fast motions.

Does anybody have an idea about the PIC MJPEG two field setting problem..why does it seem to make two fields when the setting is turned off?

If the interlaced SVCD looks jerky, try changing the Field order option in TMPGenc. If the field order (dominance) is set incorrectly, the fields will be played in the wrong order, leading to lots of jerkiness.

If at all possible, try to avoid deinterlacing. It will only harm the smoothness and detail of your video when played on a TV.

i found out tonight that if your source is 24fps and you convert it to 30fps, it will play fine as an avi on the pc, but terrible as a vcd on the tv. maybe this helps?

I have been cap'ing 640x480 ntsc (29.97fps) interlaced video from my vhs using vdub, and I've found that the best way to make an svcd is to make sure that EVERYTHING is kept set to interlaced.

If you're using vdub to frame server and/or applying any filters, make sure that the "interlaced source" is checked if the option is there (resize and other filters have this option). Also, check the frame rate setting is set to default (no IVTC). Do not add any filters for IVTC or deinterlacing....

In Tmpegenc, make sure both the output setting is interlaced, and that the source setting (under Advanced tab) is set to interlaced as well.

This has given me the best results in my quest for good ntsc vid caps...

cheers,
