Frage von LuFaHa:
Anyone who has been working more closely with PAL-cut, known fields. My goal with this forum topic is to clarify matters for the settings that relate to fields to bring in the major DV editing and compositing programs.
For those who have concerned themselves not with half-frames, still wondering why yours faster in software interfaces with their DV cameras filmed material strange lines in the area moves, I found the following links:

I ask all forum users correct me at will and easy additions to post a response to this contribution. Perhaps it can even make a reference source for some fields. If you can not understand something or have you notice that I have put somewhere very unhappy, tells me this is synonymous with quickly so that I can mend. :-) Here, I simply call the various time points in the video editing program Adobe Premiere Pro and compositing in Adobe After Effects 6.5, s.denen it comes in contact with half-frames:
Antwort von LuFaHa:
In After Effects we will globally for all the footage Halbbildinterpretation:
* Interpreted in the Project window, right click on the appropriate footage * -> * Footage - * Setting> * Footage Here, we can now provide for "separate fields," the bottom, set the upper field, or disable with "off".
After that is decided in which order the interpolated frames are arranged. After-effect that is initially separates the two respective fields and interpolate interpose the lines so that results in two frames. In real terms, but in most cases so that the project only half of these interpolated frames will come into play, since it takes so only 25 interpolated frames per second, but emerged from the 50 fields synonymous 50 frames.
Nevertheless remembers After Effects, that it has now 50 full frames are available. This comes to bear when you "frame blend" activated or slows the speed of your footage. This allows for example to half slowed yet to produce still images with relatively good quality.
Another advantage is the ability to verify this in After Effects to the field order. Clicking being double the appropriate footage (mostly avi) yes notoriously open a video window, which can play back the footage, for example, via space bar. The advantage here is rendered with all the available pictures. That is synonymous with 50 (interpolated) full-screen images. Therefore, there are an awful in the wrong field order Geruckel, whereas otherwise the video will be played normally, but with no fields. To verify, you can simply try both modes synonymous (upper and lower field)!
Disable this feature is only advisable if the imported material is already progressive (read in full frames) or if there are no effects added, but only such as a color correction is carried out. Particularly in the case of securities with compositing keying, it is very difficult to work with interlaced.
What are your experiences here? What effects can be applied inter-lanced yet?
Antwort von LuFaHa:
In Premiere, can the Halbbildeinstellungen region for each clip on the timeline individually regulate:
* Right click on the corresponding clip in timeline * -> * * Halbbildoptionen There are 4 settings: Without: Changes obviously nothing.
Successive frames to distribute fields: This function is in my opinion not very useful, since nothing else is done, when all the fields in time to set one field to the front. In the first field is cleared and the last double.
Fields join: Is similar to After Effects. Interpolated from one field, although only the one frame is the other's half frame, but breaks down (is not used).
reduce flicker: Is similar to After Effects with activated Frame Blend. From both fields a single frame is interpolated frames and the two are mixed into a single full-screen (as with 50% transparency). This is my opinion the most sensible, if you want to work progressively, as it apparently creates more motion blur.
Reverse Function "field dominance" actually only changes s.der Interpretation of Premiere something. Say it is divided amongst the "Successive frames to fields changed to the temporal sequence Rhine and join in" fields "from each of the other field. Strange, I find that in a film, therefore it is not possible to change the norm.
eg: If I make a film with PAL measurements were taken at the Field but the upper front of the lower, load into Premiere, I can not ensure that the fields are really mixed up. Say the top, the first line to the second line, etc. The first to the second, the third to the fourth, the fourth to the third Am I wrong here? Did you have it yet? If the field order stored somewhere in the video premiere and alters any information?
Antwort von LuFaHa:
In After Effects, you can adjust for the Kompostion or the Project nowhere an interlaced. From this I conclude that After Effects is provided as standard for the use of progressive materials. Whether it can be calculated eg movement) in the fields of animation layers (namely, to select only when the output (calculated fields).
Am I wrong? Has the project setting "frames" with a little half-frames (to do this after all is the display format)?
Antwort von LuFaHa:
While in the sequence settings (just as in the composition settings in After Effects) may take no half-frames settings, it looks at the project settings otherwise.
Already in the preparation of a project (and only here, because after creating the project allows the Halbbildeinstellung should not change) Finding the correct settings.
The following three setting options are available: Top field first: With animation, motion effects, and gradients are calculated fields. Focus on the content of the upper half image predates that of the bottom. This has no impact on the fields in the material (not change) the imported video files.
Lower field first: Just as the "Upper field first", only the contents of the bottom of the video field time is before the upper.
No fields (progressive scan): This is calculated animations, movement patterns and effects without the fields. Again, this has no effect on the fields in the material.
Should the "Upper field first" and "Lower Field First" are calculated for all effects (plug-in's) fields?
Antwort von LuFaHa:
hm
Antwort von LuFaHa:
Warning: The number of "hmm" s are I do not really have happened, because I suddenly had no browser access more. Now I feel that but not quite so bad. Because I write the text in Word and can then easily add more answers. So please do not delete the time being.
Thank you ...
Antwort von Markus:
Wow, there you have you have never done a lot of work! :-)
For the first post I have another suggestion: The website

... or two:
Perhaps an example would be synonymous useful are ideal for applications which interlace and / or progressive video:
