HD 60i after 50i without quality loss?



Frage von M4gns:
Januar 2009

Have tried a few shots of my 1080i Canon HV20 (NTSC) in Vegas7 as to render 50i/25p. My first impression was that they are qualitatively of the 60i/30p-Version do not differ, can that be? (as opposed to SD are in HD when the standards so only the frame rates vary)



Antwort von tommyb:

Vegas converts in fact very good.

There are two settings:
- Frames interpolate
- Frames hide

Depending on which type you choose, you'll get different results.

Interpolate frames:
Intermediate images are calculated, which is below images for a good sharpness provides. Pans Jerkiness subtle to strong.

Frames hide:
Between the images in the half blinded, so will be merged. Smoother pans, but are synonymous slightly blurred images.

And why you do not see much difference is relatively simple:
If you've rotated with 60i (ie 60 frames / second) and this post on 50i konvertierst, you will see maximum interactivity while polishing a slight bucking when panning - but possibly because synonymous only 50 frames are still so fast that your eye as they redundant exercise, but not recognize each Picture to say: Yes, the jerky.

Get with the times progressive recording (30p to 25p) and you fall to;)



Antwort von darg:

Why You konvertierst HD of 60 to 50? Your Customers Can not play or why not? Since 99% of all devices currently in standards can play in HDSegment there is no longer forced conversion.








Antwort von M4gns:

I will be in the summer of an HD movie to make. We use either a Canon XH-A1 or a SonyFX-1. I wanted to possibly be my NTSC HV20 miteinsetzen, but as the Canon or Sonyin 50i/25p recording, I had tried the HV20-60i signal to the Render Settings 50i/25p than spend more concrete terms: the meaning, the NTSC recordings of the HV20 into a (H) DV-PAL Project to incorporate?

In a mixed film scenes are converted immediately. Some people use the cameras, however, 60Hz, a beautiful slow motion to get - in this case the conversion does not occur.

in my case (50Hz and 60Hz to 50Hz output) can I use the HV20 so forgotten, right? ... When the conversion is not on (in slowmos)? How do I (Vegas), whether blinded or interpolated frames are?

If you have both options, then try it out. The frame rate conversion in Vegas, you can individually on the Underworld sample rate of the clip out. The interpolation means there "resampling". Normally Intelligent Resampling ", which means. Between pure images that can be expected. You can disable resampling synonymous but what you Jerkiness more leads.

The difference between interpolation and blending refers to the deinterlacing for rendering. That you can put in the project properties - it helps you nothing for your problem, as far as I understand it.

Here is an example of how this works with the resampling (Here I have a Geschwindigkeitshüllkurve placed on the clips):

Yes. If you have bad luck, is the whole not only through representation on a muddy, but still synonymous with a flicker / flicker with artificial light sources. And that is really out.

If you're with 60 frames / second aufnimmst and with 50 frames per second playback. Then maybe only flickers the light. When you want to simulate in Vegas, then you need a 25p/50i Project for the individual clips on Properties and then go to "Under Sample Rate" rumfummeln until it is 25 FPS.

Where is synonymous undertaken regarding the format Resolutionund frame rate.

File -> Properties -> deinterlace method [/ code]



Antwort von M4gns:

btw.: taugt the 24p mode of the NTSC HV20 something, because I am of the PAL HV20 heard, its 25p mode is not as good, uswegen to strong shakes. It is better in 60i instead of 24p film? (Slowmos were supposedly synonymous with 24p very choppy)



Antwort von tommyb:

Are you less of a frame (24 vs. 25) it is liquid?

Progressive Modis are always jerky (from consumer to Digibeta).

60i does as a liquid Picture 50i and has a bit more synonymous with Slowmotion reserves, but NTSC in Europe * * klingeling since our 50 Hz flicker light bulbs on it (just as vice versa).

If you are in search of the times "in the U.S. buy" or something similar, since you get a bunch of threads in which the problem again and again described.

PS: Slomos at 24p Jerkiness more ... because it is so synonymous only 24 pictures. And if you with 12 images per second is reproduced (that is, half the speed), then it looks just as fluid as the first black-and-white movies without acceleration;)

PPS: For interlaced material, you can naträglich a progressive synonymous Picture interpolate, which depends on the settings of either crack is sharp and jerky but slightly washed out or not jerky.

Do you have one of the two cams, or even be the first purchase?
I sell to my XH A1 (NTSC) 3-5 hours to use as new Sogut a good price!
Then the format would be perfect for your HV30 fit ;-)

Oh @ ober me ..
have you ever filmed with NTSC?
So when the flickering is my XH A1 (NTSC) soo small that it really is not worth talking about! (voted today in a Complin
dark room lit with neon tubes 30p rotated and the flicker is hardly or is not at present) only in automatic mode or if the shutter all the way down, it always revolves more!
(Wolfgang's presets using the so-incidentally, what really suck)
Furthermore, how often you're filming in areas where only neon lights are?
normal light bulbs are not a problem anyway!
I think from my experience the NTSC issue is quite exaggerated ..
Sure PAL NTSC would be better but is not nearly as bad soo all say!

These are the settings for the deinterlacing ... with the resampling for events with the project settings of differing frame rates has nothing to do s.diese settings with you right-click on the clip, Switch / Smart Switch and then resample, resample Force or Disable resample.

I achieve a better result if I NTSC after PAL HDV render as DV NTSC DV PAL after-DV (sharpness, etc.)? or what are the pros and cons?

I've NTSC HDV material both as a 16:9 NTSC as synonymous as 16:9 PAL and render times compared to single frames, it may be that the PAL picture sharper than the NTSC or am I mistaken or . how would the answer to my first question?
Thank you



Antwort von tommyb:

Picture of the net-Resolutionher PAL Picture should be sharper.

Net of the movement should Resolutionher the NTSC picture look better.

Why?

Because 60 frames NTSC HDV> SD PAL 50 frames a 720x576 pixel picture shows, moreover, where the 10 frames in NTSC together are blinded. Ie between a sequence of movement is not as sharp depicted, as in the original. This is especially for material on that with a shorter shutter was rotated (eg 1 / 125 or 1 / 250 - in relation to PAL NTSC Shutterreihen because I do not know!). Under normal 1 / 50 or 1 / 60 shutter, this is not really noticeable.

Converts HDV to NTSC 60 frames> 60 frames NTSC SD is adapted Resolutionentsprechend. You get 720x480 pixels and this is obviously less than PAL. The movement resolution shall, however, because it is only a Runterskalieren.
