Canon XH A1: Conversion of HDV DV after internal possible?



Frage von dieter.adler:
Juni 2007

Hello everybody!

Stand before the purchase of a Canon XH A1, I already have here of Slashcam and other sources of me a picture of the device can do (s.dieser body: Dickes Merci s.das Slashcam Team - genialler Verlgeich with other camcorders!) Have now but ma 's some very stupid questions, answers to which I've forgotten otherwise found:

1) Can the internal camcorder in HDV recorded material to DV
convert?

2) If yes: has anyone experiences regarding the quality of the downscaled material?

3) And if not, someone can give me a tip about a software, which is the material for capturing (or synonymous after the capture of the plate) to convert DV?

4) How is the quality, if one with the camcorder in DV recording?

5) Can the camcorder in 16:9 PAL natively record (yes, the sensor is actually designed for)?

Ok, thank you s.Alle!

Gruss,

Gabriel



Antwort von wolfgang:

1) goes for all HDV devices, the only exception I know of are the devices from JVC Professional Servi (JVC HD 100/101/200 ...)

2) the quality of down conversion of HDV to SD from the camcorder, it is generally a better track than if you do it in the cut programs from the timeline makes out. Disadvantage: it cuts the material only in SD, and not in HDV - which really only makes limited sense).

3) A Walk to the capture of DV's Page of the software rather not - if, rather then the Convert Files to intermediates, such as the Cineform products, or the Canopus HQ codec with Edius.

4) I am too little indoors - the shooting in SD devices with HDV ware rather always something that did less well (eg on the FX1). The Canon A1 is expected but even in reasonably good quality.

5) the HDV devices can normally be all in 16:9 DV recording.

Without you come too close to want to: As a rule, it is-at least with current camcorders-exactly the opposite. And especially when XH-A1/G1 the difference is striking. My tip: If no record in SD, makes absolutely no sense.








Antwort von wolfgang:

And what exactly are the "current camera"? You know, there may of us None None this camcorder all in all its details and with various NLEs test. From the newer HV20 surely we have some reports that there is the shooting in DV even better quality than if you filmed in HDV and then runterkonvertiert - in APP2.

http://www.videotreffpunkt.com/thread.php?threadid=3994

The problem with such statements is always the question
See above about the statement of the HV20 to the A1 is transferred;
b) whether we are not APP2 specifics of a talk, which is in another completely different editing program might look like. I guess times that the down conversion in Vegas or Edius may look different, compared with APP. But testing has systematsich None, as far as I know.

Basically synonymous, I think nothing of it, on a HDV camcorder like the A1 in the DV to film, and finally yes we will of the HDV Resolutionauch what did (which is normally always the case, simply because the material has good processing Reserves). But in individual cases - depending on the available equipment and the available NLE - different.

Wolfgang, I like to tell you: All the models by the manufacturer nor offered. Tatatata!



Antwort von wolfgang:

Really? Are you sure that you do not have the equipment meant that first morning of Manufacturer are offered?
;)

Or maybe those who are still in the trade?

Honestly, I think this distinction is pretty absurd when you look at what the masses s.Neugeräten industry again this year on the market will throw. And the properties are definitely not always better, often they are even verschlimmbessert because the industry in subsequent models, more and more saves. Reasonable properties in SD mode if it were a pleasant time exception. Even if I do not buy HDV devices, and then incorporated in SD - at least not normally.

Yes, Wolfgang, I'm sure I do not mean these devices have. But is really great that you have demanded.



Antwort von wolfgang:

Na but I am glad that you make the happy.
:)

But perhaps logs so the thread starter again, with his supposed follow-up questions.



Antwort von toffi211:

Hello everybody!
And then "logs on the thread starter with his probable consequence question" :-)
First: many many thanks for the hot s.alle discussion, they voted with great interest!

Ok, the decision has been made: it is in HDV rotated, cut, post "done" and then in the DV format zurückgewandelt.

The biggest consequence question which I am currently breschäftigt:
I opted for the XH A1, inter alia, decided therefore synonymous, because it only under FX7 and Co. synonymous the 25F format supports 1440x1080, which is synonymous for me from a design perspective ( "film look") plays a role.
What I question myself: if I am with this record and edit 25F how I convert the material s.besten after SD?
It is Cinform with the Aspect HD plugin for Premiere worked. Furthermore, my MainConcept MPEG Encoder Pro available, which I am synonymous with all my previous productions have coded.

I understand it, correct me if I am wrong :-):

there are probably 2 ways the material "herunterzurechnen":

s.progressiv -> DVD that is 16:9 PAL Progressive
or
b) interlaced.
What would happen now with the b) variant happen? As a codec converts interlaced progressive after?
I'm studying media technology and saw in the video department demand times, such as with "progressive> interlaced runs - that they told me only that there be" a complicated procedure ":-(

Would you all for further advice much appreciated!

Best Regards,

Gabriel



Antwort von wolfgang:

So if you pseudoprogessiv films, I would synonymous with final variant s.bleiben.

As for option b) is likely to happen is only the temporal interpolation of intermediate fields - what is the shooting in the variant ssabsurdum leads. Not only that the compute-intensive - to get better image quality by such transformations certainly not synonymous. Because you can then yes the same fields with film, if you then want to output 50i.



Antwort von charles ügo:

Ok, then "interlaced" filmed :-)

This 1080 story 50i cared for me so far for confusion, because I think that in fact at any given time (ie, we say to each "full") is only half the vertical field Resolutionvon the jewels (which together then the "full" result) exists.
Now I just thought that if I take 25p in 1080, although to me the "schlirren" when it comes fast pans, but the resolution - and thus a better picture of the impression - is preserved. Or was I wrong?

THX,

Best Regards,

Gabriel

Could someone maybe me regarding my last question or answer?

No idea what you mean exactly with Schirren. 25p material, recorded with camcorders (without wings like aperture in the film), producing at a rather fast pans Ruckeleffekt, the movement appears simple at 25 support points at 25p instead of 50 nodes in 50i as a jerky picture.

The resolution would only fully swing with a preserved if it is a real progressive material. So for material, where the entire contents of each image frames of progressive ausgelsen will chip. This is - as far as I know - when the A1 is not the case here, but there is a lot more from the two fields a pseudoprogressives Picture calculated. And if that is the case, then you will have synonymous in this pseudoprogressiven Picture by the misalignment between the two fields a certain loss of resolution.

Often discussed, but unfortunately only very few devices available remedies would only create true 50p.
