Frage von past0r:
Hello everybody,
I have the opportunity for my next film project which SonyPMW-EX1 to use. I have a fundamental question at the quoted Auzeichnungsmodi.
My concern is when to decide whether to render the film on television or the Internet / monitor screen to be played. So it is the correct project setting set - to match the recording mode of the Cam.
Somehow it goes back to interlaced or progressive
;-). I have the forum and other pages are searched several times, but never a befriedigente reply.
Question: What recording mode should I record in my flexibility to target media (TV or Internet) to remain and also the best quality possible to obtain (ie little to convert)?
Wär supernett if you could help me ...
Here is the exact text Sony:
Multiple format recording - 1080/720 and between interlaced and progressive switchable operation.
The PMW-EX1 offers a wide range of recording formats for a variety of production applications. The resolution can vary between 1920 x 1080, 1280 x 720 and 1440 x 1080 mode. The frame rate can be between interlace and progressive elected: 59.94i, 50i, 29.97p, 23.98p and 25P *- natively.
In addition, in 1280 x 720-mode 59.94P and 50P progressive recording is possible. On the SxS memory card can have multiple files in each of these recording formats is what a flexible use of the memory card is guaranteed.
* In 1440 x 1080/23.98P mode (SP) images as 23.98p and processed images using the 2 / 3 pulldown as 59.94i signals. Thanks in advance for your help!
Antwort von robbie:
In 1080 50i record. Thus you have the highest Resolutionund are s.Flexibelsten because this format without any loss of nominal value other format can make. Up to 720p50 course.
Antwort von jazzy_d:
So I get from HDV (50i) wunderschöne WMV HD 720p50. For reports, etc. with "fast frames" out of hand, I would take synonymous 50i. For scenic shots, I would probably take 25p or 720p50 principle.
Antwort von past0r:
Danke erstmal s.robbie and jazzy ...
So it is better with interlaced material to work and then Volbilder (progressive) conversion?
Changes to the 1080 conversion of the resolution 50i synonymous Or just the image frequency in 25p?
So 1080 50i is to 1080 25p?
In summary:
What must be done in the Umkonvertierenung Bachter. What is going on and what not ...
Antwort von jazzy_d:
Where does it all. For Web (PC monitor) but p is almost mandatory. It changes when you convert exactly what you keys. Try halt with short clips s.besten what you like because the opinions on this issue quite apart.
Antwort von tommyb:
I would proceed exactly the other way. Namely, all in record
720p50. Have until now with DVCPro HD 720p50 and allowed to work (self-ruled) - Progressive gives you great flexibility.
The qualitative difference between 1080i50 and 720p50 becomes visible when the player with the deinterlacer of material no longer cope (LCD FULL-HD Television are still progressive).
If I now have interlaced material, then I can convert this in turn to progressive material.
Deinterlaces s.sich today is not a problem, however, still picture information is calculated and it is never as good as direct progressive recording.
Would you use 720p50, then it would be much more flexible. 720p25 can create by using every second frame is gone. 1080i50 would be feasible in the Picture will hochskaliert and then the even and odd lines are selected. What else happens when native interlaced method not synonymous.
So my clear recommendation
720p50.
Antwort von past0r:
Thank you for your quick responses!
@ all: Now I have exactly what I actually wanted to avoid :-) As good as all the recording has been called ...
@ jazzy: There is nothing more to me now are left every other format in a small clip to test out and and her to convert.
Then will I `s synonymous first hand ;-)
@ tommy: Sounds plausible given what you said `s. .. I always had a strong quality problems when I've deinterlaced.
Only s.Rande ... What do you use when you need to deinterlace or interlace? (Synonymous s.All addressed)
Still ne question:
Whether the case material I have progressive and interlace it wants. Is this standard with the premiere of presets, or do I Trickery or even to another program to use ... (Sorry for the stupid question probably clean, but I had only to do with DV)
Good Night and Good Luck
Antwort von tommyb:
I use Avisynth to create interlaced material and of the subsequent deinterlacer. There are wonderful and well-functioning methods.
Directly out from Premiere, it should be synonymous, but without any major problems go.
Antwort von robbie:
1080i50 would be feasible in the Picture will hochskaliert That is unfortunately the problem. You resize high. And the difference of 720 to 1080 is in fact a non-negligible.
This clash is now probably different opinions on each other.
The 720er Resolutionist in my opinion, perfect sauce and the biggest mistake that it ever existed. 50p nice and good, but please do not 720th Since we would like to stay at 576 and can simply make 576p50.
As I said, my opinion is still 1080i50, if you use a good deinterlacer. 1080p25 if you really optimized for the Internet will work.
I think with good deinterlacer can 50i from a 25p, where only professionals notice the difference.
But if you want to work for television, then you right now if not over. Just my 2 cents. But perhaps there is a 3rd Opinion;)
Antwort von past0r:
So ...;-)
Basically:
What procedure has the lowest quality losses recorded?
progressive -> Interlaced or anderesrum?
Is not it easier from frames, half to make?
Korregiert me if I'm wrong ...
One question is, of course, synonymous to the memory requirements of the format ...
Is there differences?
S.alle Thank you!
Antwort von tommyb:
That is unfortunately the problem. You resize high. And the difference of 720 to 1080 is in fact a non-negligible. Difference between 720p and 1080p? Yes, very well.
Difference in 720p and 1080i? No, rather not. Why? Very easy. Because it is purely of the vertical Resolutionher 1920x540 equivalent (half). Although there are a half straight and odd lines and these can in turn be used for a picture to reach, but it really is not that nice.
Depending of the quality of the deinterlacer can lead to staircase artifacts come, especially good to see the football and the white lines.
Since we would like to stay at 576 and can simply make 576p50. So is a 720x576p50 or 1024x576p50 Picture your opinion better than a 1280x720p50? Then you wiedersprichst your "1080i50 is better than 720p50" statement.
1080p25 if you really optimized for the Internet will work. Frame and leave your material is already 25p. Most Internet platforms synonymous not offer more than 720p, because the bandwidth for synonymous still a little too modest. The high, the compression can not be influenced portals enables the material to the final blow.
And do you really think the people who surf the Internet all have a 1920x1200 monitor? Neeee ... I do not think so.
@ past0r
What procedure has the lowest quality losses recorded? Depending on what you aufnimmst, it may be as mentioned above staircase artifacts to come when the whole on a television is playing the immensely expensive and not good deinterlacer uses.
How it looks (whether good or bad) depends somewhat synonymous of material. Especially see interlaced graphics is not particularly nice. The only exception is if the material through a tube TV is running.
Antwort von Lutz Dieckmann:
Hi,
is quite simple. There is not the format. That was at times as PAL.
For quick image do you 720/50p
For scenic pictures: 1080/25p or 720/25p
I is Ok if you do not want to use effects, AE will use over the network or want. If you want these things are I pictures taboo. They cause artifacts and that's logical. Fields due to the interlacing need more bandwidth. If you create masks in AE I want is synonymous bad, because you never know where the mask is. Left, Right or in the middle. No matter how it is wrong.
Greeting
Lutz
Antwort von past0r:
Yes, progressive material when so many advantages why you are still s.interlaced think?
@ Lutz:
So what ever I can fix. is a progressive record that I will, because I with effects and AE will be working. Also the clip is mainly present in the network. (; Question of progressive change in interlaced is no problem, right?)
Quote of Lutz:
For quick image do you 720/50p
For scenic pictures: 1080/25p or 720/25p
That I did not understand? How to adjust the resolution values of 720 pictures with fast moving images in 1080 together?
Are not these pictures of different sizes?
Thank you and good night
Antwort von mierski:
With 1080i, you have a higher horizontal resolution, but because of the lower half vertical resolution (actually only 1080:2 = 540 pixels) and thus more 720p.
But I have a question about themselves. For example, images fast football, one hears again and again, 720p50 would s.besten, but the Bundesliga will be produced in 1080i (at Premiere dämlicherweise then broadcast in 720p). But what standard should we choose when all are still to be compatible 576i50 (with the highest possible sharpness of motion)? 720p50 runterskalieren and then interlace? If I have 1080i runterskaliere the half but vermurxt, right?
