Infoseite // another Ruckelproblem: export as avi



Frage von tablediver:


Sorry, that here again a Forum provides a newcomer Ruckelfrage - so far still have no solution in the other articles found on the subject ...

I've still images (jpeg animated) for an animated storyboard with "Image Pan".

When you export the movie as completely normal. Avi then the annoying "stripes" and the stuttering when I play the film in Win Media Player. The strips have wegbekommen I, as I have chosen in the Export settings in Keyframe / Render "no fields".

Now I would like to get rid of the jerk. This arises when passing pans or movement. In Zoom, the quality is absolutely ok, motionless in the same places.

Other export settings: I have now tried out a whole lot of options (NTSC / PAL and various other options). Gibts da particular combination of irgeneine you recommend? The only restriction: the film needs to be spent in 16:9 cinema format.

Area: Premiere 6.5 & ADM Processor with little RAM.

Antwort von AndyZZ:

When you say "little RAM" I suspect that he may not have enough film information temporary storage in RAM and constantly access the hard drive needs. If the stream is interrupted, then it's just jerky ...

Antwort von tablediver:

applies to the problem with the RAM to play the movie or the export?

If the latter is the case, it would therefore be sufficient to export my project s.einem PC with higher performance, right?

Antwort von grovel:

No, the RAM problems relate only to the playback.

How many frames per second have created with you? 25?

For that alone, is PAL standard, and if there are less jerky, of course. If these 25 pictures, all very sharp with no motion blur then it jerky way, so synonymous, then it will only s.ca. 70 frames per second are liquid.

Antwort von tablediver:

Ok, so then I think the reason is not lack of RAM, because the jerk export avi's synonymous to other PCs.

As I said, it is the raw material to jpegs, they have a relatively high resolution. A Bewegungsungschärfe is inside the starting material ie not with.

I have the whole thing already with various export settings, so PAL / NTSC and synonymous 25, 29 and 30 frames per second - the stuttering went away. I found no option to even more fps. issue. Grovel wrote it to be around 70 frames / sec is necessary. How do I do that?

And why is it only occurs in jerking movements, but not for the zoom in the still images?

Where's probably because I have to use "no fields set in the export options? But I'm just this rausbekommen interlaced stripes in the movement ... I also dache, the interlace is only useful if you want to play the movie on a TV? I simply need an avi which runs smoothly on the PC ...

Antwort von grovel:

70fps you will not unravel, of course, that was only meant as a visual reference.

What you need is 25fps PAL, if it's meant to be watched only s.PC not interlaced.

The problem is that your source material is indeed still images (on which you swing, right?) So you need the program (which is the calculated reinrechnen panning motion blur that can almost all, if you can find the option). The problem is that you usually just 25 frames, and the sharp of eye, yet be perceived as such and not translated into a movement.

Why in the zoom in the still image does not occur, however, is somewhat puzzling. But probably an optical illusion, ie, takes the eye of truth in this case the jerk is not. Or, at zoom motion blur is included, as opposed to pan.

Antwort von tablediver:

Ok, that sounds plausible!

I'm using Premiere 6.5 and the effect "Image Pan" to create the movement of the still images.

Does anybody know how to get there reinkriegt motion blur?
And why is not jerky when zooming? (Zoom, I also generate the Image Pan Effect)

Hello grovel,

try the following times:

- The reference point 1 amended
Currency can represent still images to 16:9 output size to the width can vote already. It should be expected, in pixels. What s.Height too much is ignored and an appropriately chosen equal to other selection mask s.der graphic itself will change nothing. (-> Graphics program!) Better, however, the images should be available already in 16:9 format. All pictures should have the same size, so that when you play does not lead to distortions.

- From point of pass 2, because wrong ..

- Export to AVI with codec settings accordingly accurate. (real video data rate, frame rate, planned output and memory size) Here one should not be so stingy, if the output quality should be good. Now, should not see flicker no more fields, and there are not synonymous.

Antwort von tablediver:

Ok, so I'm now trying times, do it so as tohato suggests.

So new project created in Premiere 6.5 (DV playback timebase 25, 25 fps, Frame: 720x576, no Halbilder, Compressor: Microsoft DV, square pixels)

Then the images changed to the same format (2400x1920 are now - a multiple of 720x576 ... or is a fallacy here somewhere?)

Imported with a length of exactly 25 frames and get checked in "aspect ratio".

Then dragged to the timeline and drübergelegt the Image Pan.

Exports with "work area as a Microsoft DV AVI, 720x576 with 25fps, Kompromierung: MS DV (PAL) with 100%, Compressor: uncompressed. Under keyframe & Render:" No fields ".

The result: http://www.tablediver.com/testexport9.avi (8.24 MB) -> there's even a waving and even a zoom in it.

The jerky is unfortunately still there ...

Hello diver table,
So I see it s.dem format, the representation would probably rather 4:3 (with an aspect ratio 1.25) instead of how you want to be 16:9. Otherwise you'd have to adjust all the images, which would then be 2400 x 1350, if the width is correct. Top and bottom were then cut off 285 pixels ". In the graphics program you ought to you for the new Picture mask create a copy, which you ought to apply in each case, to save you work with the mouse. In the video, the 405th would be 720 x So just forget it

The jerk I explain it to me that the picture 720 x 576 for some PCs is too big. Since many PCs already s.The pushes boundaries and synonymous not everyone has all the codecs installed, you must remember that in the transmission of the video. The sample video takes' a while until it all starts erstmal, but if it's going, then runs it. I would Offers from you in the issue 'ne smaller size, such as 640 x 480 or 576 x 432nd That was with the 1 picture per second 's wrong of me. This only goes so if you want to reflect individual images without movement. The less you set, the more jerky.

At the compression is still to be worked over 8 MB for 2 seconds is too much. Because ultimately determines the available storage media on the setting.

Greeting
tohato

PS: I use - Virtual Dub (Mod), Ulead Video Studio 7, Adobe Premiere is too complicated for me.

Antwort von tablediver:

Thanks for the nice examples!
I no longer believe that the jerk has to do with the greater the output images, which had again tried.

To go forward now, first let me have just continued s.Schnitt and thereby realize that it will not be many places in the movie where I need to make rapid panning of the images. In slow motion and zoom the quality is not so bad ... If the fast pans with not equal to the jerking s.Anfang occur again between the film and are quieter sequences, it is no longer particularly disturbing, it really falls to only if you listen closely on it respects.

Maybe that would help lower Resolutiondes film, but I would like to run the film in full screen on PC-Monitor/Beamer and will therefore make no concessions in the sharpness / picture quality.

1000 thanks at least for the many tips and your help!

Hello diver table,
then you should still take 720x576, but with a good codec. If there are very many pictures, you gotta earn only about the memory size be aware of that, when setting the codec bit rate calculator to help. Do you plan too little, the quality will be worse. In any case, must be compressed so that the PC with reading comes afterwards. Test times a Picture with the codec used, let's go through it and you know how much you need to plan, then give a little added.
- With 25 frames per second:

Even with 25 images is virtually seamless.
