I am successfully copying dvd to vcd using TMPGEnc and Nero but the motion seems jerky to me. Can I correct this in any way?

What exactly do you mean by jerky? Check to make sure that you have the field order correct if the dvd is NTSC (if its film then the stream is progressive.)
-
If a car is moving down the road it looks like there are frames missing and the action is not smooth. I'm not sure what you mean by NTSC or progressive.

Do you mean NTSC rather than PAL. I only record from PAL

How exactly are you converting to VCD from DVD? Which guide are you using? Bear in mind that almost all PAL DVDs are progressive, and following some guides for NTSC will result in the problems you describe (eg using Forced FILM with DVD2AVI). As a matter of interest, what is the actual framerate of your VCD?
-
I use Smart Ripper then DVD2AVI then TMPGEnc. As a guide I used the one from this site. I set TMPGEnc to best quality but other than that I have not changed anything from the default PAL setting. I don't understand the term "progressive". Any advice you give me would be greatly appreciated since, apart from the jerkiness, quality generally is superb.

I have looked at the settings. For DVD2AVI I have been checking "Forced film". If this is wrong which should I check?
My setting for TMPGEnc are:
VIDEO
Size : 325 x 288
Aspect ratio : 4:3 625 lines (PAL)
Frame rate : 25fps
Bitrate : 1150
VBV buffer size : 40
Motion search precision : Highest quality (very slow)
ADVANCED
Video source type : Interlace
Field order : Bottom field first (Field B)
Source aspect ratio : 16-9 display
Video arrange method : Full screencarpe diem maņana -
Field operation in DVD2AVI (for PAL) should be set to "none". Using "Forced Film" will definitely cause problems. It is not appropriate for PAL. Most PAL DVDs are "progressive" rather than interlaced. So your video source type in TMPGEnc should be set to non-interlace(progressive). Field order then does not matter.
Source aspect ratio is usually 16-9, but can be 4:3. Which one to use will show up when you run DVD2AVI. DVD2AVI very frequently reports an interlaced source when it is not. Your best bet to detect the few PAL interlaced movies is your eyes when running DVD2AVI. You'll know when you get one!
Video arrange method I would set to Full Screen(keep aspect ratio). This will make sure you don't lose any of the original picture, and the aspect ratio will be correct, presuming you have not chosen 16:9 when it should be be 4:3. 8) Whichever video arrange method you choose, make sure it's an option with *keep aspect ratio*. -
Cheers! You're a star!! Can't wait to give it a go.

When you run DVD2AVI on a PAL source with *Forced film* checked, just look to see what framerate is displayed when you press F5. This will give you a clue as to why your VCD is jerky. 8)

Hello there
I know what you mean. The motion is jerky. If you want smooth motion like on TV, use mpeg2. not mpeg1. And not non-interlaced. Have it interlaced. It'll be smooth. As for mpeg1 smoothness, I don't know if it exists. Does it? Probably. I can't seem to find an answer on that one. I myself couldn't to date make mpeg1 smooth files. Somebody who knows, please help. However, interlaced mpeg2 files I know are smooth. Don't we just all loooove smoothness? I know I do. K Bye -
That's just nonsense. VCD should be just as smooth as SVCD. The framerate is exactly the same. The difference is in picture quality. There is also no point in trying to interlace a non-interlaced source - it is meaningless. Do you actually think before opening mouth?
-
I tried it and the result is superb. I made an SVCD copy of a French film, Delicatessen but without subtitles. Do you know any way of getting the subtitles?
carpe diem maņana -
There are various ways, and various subtitle formats. I've only used Vobsub. If you use something like PowerDVD you can switch the subtitles on and off. If you want to add permanent subtitles then one way is to use Virtualdub with the Vobsub filter and frameserve to TMPG. There's a guide here http://forum.vcdhelp.com/viewtopic.php?t=87065 or you could look at www.doom9.net or http://www.svcd.cc/index.htm which both describe different methods.

Dear Banjazzer
Nobody said to interlace a non-interlaced source. Secondly, even though the framerate is the same, de-interlaced video is more jerky than interlaced video because interlaced video has 50 fields per second (PAL) that will look like 50 frames a second when viewed on the television device. The result is ultra smooth video with a very LIVE look. Different than celluloid film which has no fields. Therefore, when de-interlacing video, even when still 25fps it will appear more jerky than interlaced video at the same frame rate. Burp! -
When in a hole, the advice is to stop digging.
The reason for the jerkiness in this case is nothing to do with interlace. It is because *Force film* was being used on a PAL source, which typically will produce 20fps sec output. I think I even once saw 10fps after doing this. This is the result of the jerky motion. The source is progressive - ie not interlaced, so interlacing is hardly a sensible suggestion.
Have it interlaced. It'll be smoothNobody said to interlace a non-interlaced source. -
Dear Lacky
So on an "unrelated" subject then, is it possible to get mpeg1 files to be smooth as interlaced mpeg2 files? Is it? And not ghosting. Interlaced mpeg1 files seem to be ghosting on TV because of seeing both fields at once. So my question is, can it be smooth? -
Nearly all my (S)VCD/DivX are from PAL sources, which almost invariably are progressive. I've only ever come across 2 PAL interlaced movies, and the rest of the interlaced DVDs were from TV show material. To get an acceptable result I always de-interlace. For DivX it is necessary anyway, and I have never converted any interlaced material to SVCD. Maybe if I had, the result might appear smoother on a TV, but would probably not look good on a PC. I don't knw, because I've not done it. However, everying I have produced from DVD always looks smooth to me, whether from an interlaced source or not. Interlace is not supported for VCD anyway, which is what I tend to convert TV show stuff to.
-
i had the same exact problem, you have to match the field order of the original movie, either top field first or bottom field first, get bitrate viewer , it will tell you the field and if its interlaced or progresive.
-
Jeez! Who opened the asylum? The problem is solved. It ain't anything to do with interlacing or field order.
-
Well, I asked the question and I'm more than happy with the answer. Non-interlaced for me!

"Interlace is not supported for VCD anyway".
The above quote is what I now thank you for. That is all I wanted to know (ref: "...can mpeg1 files be smooth?") Basically, the way I understand it, it's pointless to make an SVCD of mpeg1 material. SVCD should be made of mpeg2 material. So you're gonna make a vcd of mpeg1 material. Now, take the above quote into consideration, and you shall find no, you can not have a vcd as smooth as normal video on TV when the vcd is played with the DVDplayer. That's sad. Real sad. K bye -
well i'v made over 500 vcd's and now i'm doing dvd's, the field order issue was mainly pertaining to dvd to dvd conversion. just trying to help
-
All I can say is that every SVCD I have ever made, either from DivX or DVD is not interlaced. I don't notice any difference in smoothness between these and the many SVCD I have downloaded, nor for that matter to the original DVDs or the many VCDs I have made. Maybe I am not very discerning.8)
When I next come across an interlaced high qualitysource I will experiment further. -
It's easy to get a source. Go tape motion with your DV camcorder, at high shutter speed for clear motion difference detecting. Then, watch it on TV. Then, de-interlace it on the PC and tape it again on a tape and watch it on TV. You'll see the difference. Same frame rate, NOT same motion. Now you may ask what the high shutter speed was for. That is not a necessity. However, with a high shutter speed, the motion on any single frame is not blurred from where it originated to where it ended during capturing of that frame. So, after having it deinterlaced, you will especially see the jerky motion because frames won't seem to blur into one another. However, do not even go into the subject of high shutter speeds maybe causing the problem. The high shutter speed is not the issue. It'll just emphasize it so you can see the difference between interlaced and de-interlaced video.
The reason I believe you're not familiar with this difference, is because you only watch it on a computer monitor. Heck, on a computer monitor 8 fps looks smooth enough to aknowledge as a motional illusion. Even 6fps still looks like motion. Especially to a relaxed person not in a very alert state.
Now, from what you've blabbed so far, it seems to me that one will not have with VCD the smoothness of the original material one would get in the above example of shooting with a DV camcorder and playing back on TV. Or taping any TV show from TV that originated on PAL videotape of any normal kind.
So, having established that, I now rest my case. Whatever that means. -
The point is, I am not talking about DV camcorder material, which I know is interlaced. If I was processing DV camcorder material for use on a TV I would leave it interlaced. For use on a PC I would de-interlace it. I accept that de-interlacing will probably produce a worse result in this sort of case. However, what I am talking about (and what this thread is about) is producing VCD or SVCD from a PAL non-interlaced DVD source. So interlacing, whether for VCD or SVCD is actually irrelevant. You are wanting to talk about interlaced sources, and the result of leaving them interlaced, or de-interlacing them. This is very interesting, but should be a separate thread. The lack of smoothness here is because *forced film* was used with a PAL progressive DVD. 8)

i have a similar problem but not in vcd's, in making a divx. the playback seems jerky, not alot or big jumps but as if it needs to catch up every so many seconds or something. im using virtualdub. i never had any problems before but now i cant get past this.
any suggestions
