Frage von Bruce McGivern:
Hello Leutchen =)
So yes, I'm new here and have nothing better to do than to spam the same: D
Shortly about my equipment:
I film with a JVC GZ-HD7 (yeah I know there are better ^ ^) in the basement and have a Greenbox (size 5 * 3 m) of 4 * 500W Halogen headlamps above and 2 * 500W Halogen headlamps illuminated below.
The big problem lies s.Platz. My room used is not very big and therefore I can not exactly synonymous objects far removed of the Greenbox. In any case appear to the people again and again the green edges with all the strength I (I am using at the moment Adobe Premiere Pro 2.0) can not wegkeyen: (
Are there any tricks which I attach importance to? I'm trying to have people with dark clothes possible to occur that makes things easier and synonymous with the sharpness setting, I have already played (but in a wall / object distance of approximately 50 cm little sense ^ ^) but I get these edges are not gone.
What can I do anything? Should I align the headlights determined? My actors are usually in the same light as the Greenbox.
Oh yes I come along with this White Balance of the Camera still not clear! Do you a few tips for the Camera? I would be really grateful!
Thanks in advance
greets
Antwort von thekloi:
Maybe you can so a Screenshot of gekeyten material posted, we can ensure you have better times and help the tips would not be so general.
On the White Balance: Preset 3200 (the small Glühbirnchen)
To Lighting:
- Is probably the most evenly lit background?
- Are the people probably are not too much synonymous lit?
Try perhaps a smaller headlamp with red foil on the back of the hair and shoulders of the person to shine in the direction of camera, beautiful, high up so you can not see him ...
Show that you are synonymous as much depth as possible blur from the camera out. The camera also obviously in the HQ mode!
Antwort von thekloi:
Thanks for the quick response
So yes it is anyway on 1920 * 1080 (although this cam really ugly streaks in the images makes pure, it is possible by tedious umkonvertieren While wegbekommen but it affects the quality! Bin but at the moment with 1440 * 1080 synonymous satisfied)
Yes with the screenshots ... Sry I forgot in a hurry>. <werd>. <
Do me today with an external hard drive (500 GB) augestattet, and a mini-Television of the representative should serve as a monitor. However, here again the problem (sry if I vllt differed from the subject but I believe is better than a new post) that I am the Picture (as well as the display of the camera) is not the same shows as the later recordings.
Where someone randomly? For outdoor scenes, or so it is not disturbing but Greenbox and recording with Microphone is extremely annoying when the screen appears all is well and we later see that then but the Micro reinhängt or beside the Greenbox the basement wall from the shadows.
Are there any programs for stream s.PC or so, for the JVC GZ-HD7? My old Cam (SonyDCR-HC24E) had the appropriate software, and the stream showed me EVERYTHING!
Is there something of JVC synonymous? The monitor with AV connection also shows only the display section -.-
Phew now I've written a lot again! Sry for the nerves, thanks for answers!

Antwort von Fantomas:
Wrong program, false keyer. Drüber ever thought to buy After Effects? Since everything would be easier viiiieeel. And even in your Mikros Picture would be no problem ....
Mylenium
Antwort von robbie:
Yes, with the whole AFX would be easier, because you then have more control.
On the subject of image: These are the so-called over / underscan. There are again different areas, you should note. Google will help here next.
The Picture of Camera seems generally to be quite blurred, so you schonmal some s.Rand reinbekommst hem. Do you have in Premiere you have with the settings of "similar colors, or so busy?
Antwort von Bruce McGivern:
yes with the similar color I already considered. If I always between about 20-40%. After Effects has done more to recruit than Premiere Pro? I think Pro has lots of settings ^ ^
What if not the key chromakey because sonne should I take?
Hm that with the over-and under-scans I already search on Google but found nothing clever: (naja ich werd mal browse the forum.
Yes now that you say it, it is synonymous to me noticed that the picture is quite blurred. Hm net is easy to set the sharpness when you need to film himself: D
But with the remote control and the monitor will need to be working.
In any case, thank you times for your help
Antwort von robbie:
Well, you can use After Effects for a couple of other things still set how soft edges, etc., and also operates the keyer (may be that only the Pro - Version correct) are much more accurate.
Say you've just relating to Overscan found nothing ... Look at Wikipedia, the schonmal article is not bad ...
Well, the focus ... and exactly how sharp your Camera is I do not know ... Try the tip of the top with the 2nd Headlights in a complementary color of the back on all the cases, which often works wonders.
And well, otherwise adjust the sharpness, for example with a ladder, which is exactly where you stand is where you'll ... and oh yes ... do you know how to properly focus can? with zoom and so?
Antwort von Fantomas:
ok hab for "over / unterscan" wanted since he found nothing but now I already was! thank you =)
that with the flood light, I must try it, only a red foil rise, so you knew where you do not accidentally herbekommt something? * * grübel in any case it should be very fire resistant, such halogen so often reach temperatures up to 350 °!
Focus? Well in my Camera's I Mauell mode, you must press a button front and behind s.Rädchen can then rotate the lens to focus. Or there's a better way?
Antwort von robbie:
Such films can be found at music stores and dealers. The process with this film is partly controversial. In decent lighting and a good keying is normally not necessary.
On the subject of focus:
You zoom out s.das scharfzustellende object so that you have a hard edge, etc. can make good sharp. Zoom back to your desired focal. Voila. So you can more accurately represent sharp. (Background: When the focal length changes remains sharpness level!)
Prerequisite for this is that the Auflagemaß of Optics is correct. With your you can not change anyway, so will probably fit.
Antwort von C.I.W:
Free gehts but synonymous with Blender. But since the problem is that you are always with alpha masks are not green bodies rausmachen need. Time consuming way is really not.
Antwort von AnZaMa:
Time consuming way is really not. But I could picture for picture in Photoshop and transferred individually cut = D But this I would not synonymous Greenbox ^ ^
But ok now I have a lot of really great tips too! Thanks again! But nevertheless I nerv next ('m so common >.<): Could I take a film synonymous take a tinted glass? Easier for me dignity of the assembly and the acquisition are coming! But I will look at the sharp tips try vllt synonymous works so!
Thanks again
Antwort von thos-berlin:
The question is: Is HDV at all suitable for keying?
The key is in the unmoving bodies quite well. Only if the moving bodies, the green edge right ugly. That makes me a little in Rrichtung "problems by MPEG compression" type.
Your HDV Experts: Could it be a problem of incorrectly processed fields be?
Otherwise would have to consider, depending on the background image to a suitable Keyfarbe take. Then the problem remains, but it is perhaps not so visible. That, depending on the foreground-background another key combination is more suitable, one sees that even in professional studios four different curtains available. Green and blue for chroma-key, and beige for Schawrz Luma Key. In your case it would evlt. a blue or black background better.
The lighting you could possibly still optimize and tighter clamping of the cloth so that no wrinkles and shadows are visible. This could s.dem parameter similar colors are more varied, although I assume that there is no longer out.
Do you have the opportunity to bluebox Recording with an (almost) uncompressed codec directly into the PC to make? So somehow directly outputs of the components of the Camera in a fitting Videokarete? Experts, is not my playground ... ;-)
Antwort von alex400:
Yes with the direct Keyen would be a hammer but I have to first find out how I ever a live stream with s.PC camera can do ^ ^
And Premiere Pro is in capturing not synonymous grad der Hammer.
(honestly has up to now has never been a recognized Camera! naja schaut glaub ich synonymous to other outputs than USB / Firewire)
Yes, the sentences with the werd I now synonymous probably acceptable, but the wrinkles are less so because the problem.
So now I've a bit with all the possible keys played. The result is still not perfect, but at least had the edges of green to a dark blue (?) Can be reduced. It should be noted is that this is still the old material (that is, with the sharpness setting, etc. I have not played yet.)
2. Test Video
It may be that the camera is not the best but still better than my old ;-) (the SonyDCR-HC24E)
Compression is good ^ ^ The fact that said material, without conversion extremely striking stripes in the Picture. Therefore, I must at the material. Wmv format. Thus I choose the best quality (1440 * 1080) maintained.
greets
Antwort von robbie:
Please inform yourself about the strips, which are interlaced stinknormale - Strip ... which is normal ... and if you have the fun in wmv umwandelst is ever the beginning of the downfall ...
ALWAYS as much as possible in the best quality format. And there is one wmv with distance NOT ...
Antwort von thos-berlin:
I said not really, to live keyen, but with the utmost Quallität the material in the calculator to get there as usual to keyen. If you actually next with a downscaled gekeyed material, then it is clear that it does not work.
Please edit your video as long as possible in its original format, even when the memory requirement is higher. Here s.falschen no end save (if it really should be). Space is almost the most important thing in video editing.
Just to Keyen you need the best possible resolution (pixels s.Besten way). Compressed data can provide the necessary information is no longer sufficient Quallität return.
Antwort von WaldemarSchuh:
yes I am. wmv synonymous not happy anyway and I've an external hard disk with his half-terabyte increase so space is not the problem but I can easily nciht the material on hd output without converting interlaced strips.
The only way is precisely the material. Wmv to convert because it is the resolution on hd and the streak is gone. . avi is just a maximum of 768 x 576th And I've managed irgendiwe times the material even at 1024 * 768 in avi format to bring but please do not ask me more as I've angstellt>. <
How could I because these interlaced strips s.besten wegbekommen? Would be grateful if you knew there acuh tips.
Antwort von WaldemarSchuh:
A small tip for general keyen I have (although I think the help you not very much at the edge).
Simply by mask (and if only one square, which comes in premiere) as much as possible schinmal off. So just four point-ne maske to the actors around. Then, the keyer is less to do. the less green you still have, the less green tones, you will usually have synonymous ...
Antwort von thos-berlin:
The mask is a good tip, especially since it is synonymous large blue and green walls can save.
But in this case is exactly bildwichtioge parts from the front, the stripes are s.denen.
For the entire HDV issue, I must fit, because I not in the "DV-world living." But I think that the HDV as MPEGs saved.
I understand however, is not synonymous to Workfow, one of the results.
Under normal circumstances, the video material with a 1:1 in the editing program interierte Caputing tool in the calculator fetched. The Timeline Settings "fit" for imported material. Then the cut and Effect in the editing program and then made the turn off Egebnis / exported. Dabi should initial the file (if necessary) to be changed. Where this ette arise as an intermediate step WMV files? Or edit and captures the Materail you with various programs?
Antwort von robbie:
The interlaced - Strip are "normal", you have not you wegbekommen to Keyen them. This is synonymous with whom.
If you look at the fields for the finished video wegbekommen want (for example, because it is synonymous ONLY PC - Monitors to be played), you can do that in Premiere when exporting - Film - Settings - Keyframe and Rendering - Render Options - no fields (progressive scan).
Antwort von WaldemarSchuh:
yes of course I use the mask synonymous, because I always by the overscan part of the basement wall mitfilme ^ ^
The files are so-called 1:1. TOD files in the MPEG uwandeln can by allowing them to join. Renames mpg: D (why is that so now I know not synonymous but no preference>. <) Well that is when I would bother Keyen but not say the material does not look particularly great with the interlaced strips.
I try it again with your tipp. although if I have to. avi spend then I had until now always been a problem at play. obviously these files are always "corrupted" ... in the premiere so I can work but the stripes are still there. but you mean these strips are gone when I burn them on dvd and finally s.fernseher would play? Vllt is that yes, they are then finally away or come back when s.pc then this DVD is playing?
Antwort von robbie:
da gibts somewhere a fine thread (I find it sadly grad net) where everything is explained very well ... he is somehow "why do my videos s.pc so scheiße" or so ...
briefly summarized: for TV you need interlaced material, for the pc progressive. or you just try the vlc, which has a good deinterlacer built. then you can synonymous s.pc interlaced material super play ...
Antwort von WaldemarSchuh:
then, they are not interlaced with me because I use stripe vlc and in which I have the streak just like any other player ^ ^
I make myself look at the search ahoy ^ ^
Antwort von RupertGr8:
so what I've already forgotten are screenshots>. <
So here and screenshots of these strips interlaced with me:

There a fine thread somewhere [...] where everything is explained very well ... he is somehow "why do my videos s.pc so scheiße" or so ... Are you here?
Video recordings s.Computermonitor not look good I was in the wording of the heading on the use of socially sanctioned words omitted. Presumably that is why the contribution was not be found. ;-)))
Antwort von Sportler69:
again just want to briefly mention about interlaced strips: strangely said strip NOT appear when I'm with the included software (for Everio PowerCinemaNE) look, the stripes seem strangely not. Is seems s.player ... but yet they are as>. <and is the only way they move and a functional material to be flat. wmv ^ ^
synonymous if I think the rape my material but unfortunately gehts net otherwise:) can it be that my computer (1024MB RAM, 1.6 GHz double core) may be overwhelmed with the hd-avi format?
Antwort von michigrunf:
1.6 GHz dual-core notebook sounds. As could the hard drive is too slow for HD in AVI format, external help is not as synonymous if they have USB. And let this WMV format - so you can not keyen only produce green grits.
The Interlacer is, as far as I know, when VLC is off by default. Take a right click into the video and such you under Deinterlace from an algorithm.
And if you have the material with Premiere want to edit, it would possibly make sense, it is expected to capture.
