Infoseite // HV20/30 - the mode for subsequent film closing date?



Frage von scrooge:


Salü together

I know that the issue 25p/50i and FAZen the topic has often been discussed.
But somehow I still have no satisfactory answer to the following question:
If I were with the Canon HV30 to shoot a movie, later on film (16 or 35mm) ausbelichtet be - should I be more in the 25p mode for filming and throttling on 24fps film then adjust the sound? Or should I filmed in 50i and the closing date can deinterlace the movie?

Additional question:
How is it when the film both as a PAL DVD, Bluray and Film should appear?

Gruß,
Hartmut

Antwort von der_kleine_techniker:

Progressive rotation.

Interlaced material you see it always, especially with magnification and closing date on film

Antwort von Schleichmichel:

Why would 16mm in question?

Otherwise I recommend synonymous progressive, if you have not 1 / 25 exposure time festgenagelt, but is synonymous 1 / 50 can use.

Antwort von scrooge:

Thank you for your answers.

Meanwhile, I have at times synonymous Swiss Effects inquired - a well-known tape-to-film manufacturer.

Here is an excerpt of the answer:

"It is true indeed that the Canon HV30 (same as with any other HDV cameras, the chip reads 24p or 25p) progressive images in Fields (fields) are stored (so-called" progressive segmented frames, 25PsF). The Recording is "true progressive", but the processing of the frames in the camera.
What this process for the picture, is not entirely clear. In our tests, we have only the interlaced version tested because we are generally not of such a "real" progressive modes advise.
In half the material can be rotated (if necessary) before the transfer to film in the post-production de-interlaced (which is generally better than if the Camera "internal" in real time through such a process). To that extent you are in no way bad, if you shoot 50i.
To the differences in screen size can be assessed, we recommend that before the shooting a comparison test. "

Seems not a simple issue to be. :-)

Antwort von Schleichmichel:

As far as I know, but synonymous, despite the progressive image recording still interlaced video on tape is written. But that should then no longer pose a problem because of the change in the File Progressive must not simply be deinterlaced.

Antwort von scrooge:

Yes, I think synonymous, the problem is that the swiss people it effects with 25p recording of HDV have not even been tried.
However, it sounds like the real-time deinterlacing in the camera with a reasonable deinterlacer in the postal match.
Again the other:
Are there not synonymous interlace problems (with very fast movements), the deinterlacing is not as simple can be solved?
Again, turn the other ;-):
Is not very fast movements synonymous 25p turn a problem?

Antwort von Schleichmichel:

They have, perhaps an expensive processor deinterlace rumstehen, she with you to put the bill want.

At least it sounds here ... "What this process for image quality, is not entirely clear. In our tests, we have only the interlaced version tested because we are generally not of such a" real "progressive modes advise." .. . so for me, as if someone upset.

What do you s.dem process Interlace Progressive Video with raw headers in a video with Progressive header convert-not entirely clear how a non-processing of quality. Only the conversion of HDV material into a final format brings quality, but the closing date it may anyway be a bit larger. The printer does not have performance problems when you get out of your HDV an image sequence of uncompressed TIFF files do.

Nevertheless, one should test, if the budget allows. Alone, to watch how the colors from the set to behave.

Antwort von B.DeKid:

Gude

I know only as interlaced to shoot, then later if needed procedures deinterlaced via compiler.

Progressive filmed has somehow limited the right qualified.

And I think that the 24 FPS mode is not really movie mode is, I think are at 24.96 FPS real movie material.

But Markus WoWu or because you can certainly give professional advice.

Antwort von Schleichmichel:

Yes, I've written "you will not be provided on 1 / 25 exposure time festgenagelt, but is synonymous 1 / 50 can use."

Know the HV30 is not and does not know whether there is. If not, I would in any case advise against and in interlace work, otherwise smears.

And the question with the 24fps probably aimed less at the cinema mode, rather than with problems of the proof with regard to the sound. That with the xx, 96 with NTSC you bring up. Since you have not quite clean 30fps, but 29.97.

Antwort von beiti:

It is not the record as a full or half. (The recording is only a half due to the HDV - Standard and has no negative effect on the subsequent use as frames.)
What is decisive is whether the chip really is progressively read out. This is of different camcorder to camcorder.

According to my information, the HV20/30 true 25p (or 24p in the U.S. version) - that is, the chip reads the HV20/30 actually 25 full frames per second. In this case, the 25p mode in any case better than a subsequent deinterlacing, at least for the moving pictures with detail loss would entail.

Absolutely not to compare is with the pseudo-25p some other camcorders like the Canon A1/G1. Apparently, the chips of the A1/G1 unable to make out to be progressive. (In other words, the Canon then honestly not 25p, but 25f.) This is indeed only a camera intern deinterlactes Picture, and is as synonymous to conclude that a later deinterlaces better results.

Swiss Effects has apparently not made the effort to the technical data of the HV30 closer, but the "best" 08/15-Methode set.

Weiss because someone what exposure times in 25p mode possible? The times would be an information which has not yet been x times recapitulates.

That is the problem. Only 1/50tel Shutter looks good, what any automatic bans per se.
Apart from the fact that it supposedly quality deinterlacer (I read of a script for Avisynth) gives, with which something more out of 50i, as it offers the progressive mode (for the "f" models), I would like to know 50p bring what if the target format film.
I have stuff of "i" material seen ( "Until the elbow"), and one sees Kammartefakte if the picture is correspondingly large (canvas).

Antwort von scrooge:

So after some reading in various threads and your responses, I will just 25p to use and the shutter is fixed to 1 / 50 represent. Then, depending on the exposure of my auto or manual may be synonymous.
When my test images confirm the quality, then I will rotate so that the film, because for a trial closing date, I would like first to spend no money.

Thank you for your statements.
