Newsmeldung von slashCAM: Panasonic HMC-150/151 AVCCAM Review of thomas - 18 Dec 2008 02:00:00 The Videomaker Magazine has Panasonics HMC150 AVCCAM (HMC151 baptized in Europe) are viewed: a positive assessment was the low weight, the XLR - audio, the many possible recording (1080/60i, 1080/50i, 1080/30p, 1080/25p, 1080/24p native, 720/60p, 720/50p, 720/30p, 720/25p and 720/24p) and the variable frame rate, high bit rate recording (maximum of 21 Mbps) and good image quality. Negative, only the high CPU requirements at the intersection of 21 Mbps AVCHD material seen.

Where is the problem? With a good Intermediatecodec (Canopus) makes it with an impeccable image quality just as comfortable cutting, as with DV material!
MPEG2-HD, I am too lazy native synonymous with the cutting, so I just transcode previously.
The conversion period is however strongly CPU-dependent, but the advantage of high scalability with increasing CPU clock and increasing the number of CPU cores has. Space should be present in approximately 90 ¬ / TB no longer be a question of money.

gruß cj The reversal of the manufacturers of video tape forces the user to adapt to yes.
The pressure for double entry is likely in any event, the storage media manufacturers very happy.
There is already synonymous with disk mirroring systems, which the auto data (2x 1TB in external enclosure).

With a good Intermediatecodec (Canopus) makes it with an impeccable image quality just as comfortable cutting, as with DV material! If you choose the same as the intermediate AVC-I has not only the advantage of a 7-fold lower CPU load but still the synonymous, the better codecs and thus less loss.

If you ever come to Austria should WoWu, then I try to imagine a not compressed H.264 taste our wines div situation may present.
You can at any time to enter into this invitation, I would be happy ..........

Now only the question with the (consumer-) tools to AVC-I from AVCHD can produce. Can you still write something about this please WoWu? I am synonymous that AVCHD is not necessarily in mpeg2 or AVI Converter HQ needs.

Now only the question with the (consumer-) tools to AVC-I from AVCHD can produce. Can you still write something about this please WoWu? I am synonymous that AVCHD is not necessarily in mpeg2 or AVI Converter HQ needs. Also Edius 5 - is synonymous to the AVC-I codec included. Wesendlich whereby the conversion takes longer than in the HQ codec knows God is not bad.
Antwort von WoWu:
@ Jazzy_d
Stephan has basically been said already, the time advantage is not to achieve, but we still must distinguish whether the signal from an AVCHD Main Profile, as it Sonybenutzt and CABAC is used, or whether it was from the high profile, as it Canon / Pana use.
Synonymous One must not forget that it is in AVC-I is a 10 bit format, the Canopus HQ (without +) is still a 8bit format.
We, however, did not refer to the speed, but to the additional features, to use, and the whole into a 10 bit workflow integration. And it works fine.
Incidentally, I think the Canopus HQ synonymous not bad ... no question about it ... only just go the extra features in terms of color Resolutionund lost.
BTW, when you look at the difference to speak, I now know not what kind of profiles in Comparison to Stephan has come, but the High Profile Case behaves the already significantly different than in the Main Profile, Main Profile because it uses precisely to any additional improvements, the AVC really has to offer.
This comes naturally to us the question of the SNR, which is not so superficial in another image expresses ... synonymous and the related question of the key and quality of the multi-generation behavior.
There are so many reasons in its original format to remain synonymous if they are sometimes not so superficial "on hand" lie.
Antwort von SteffenUp:
Hello!
.. since yesterday I am now the proud owner synonymous a HMC151.
For all Windows users are not with the native processing of the data clearly come AVCHD (I agree since a), can I use the MainConcept AVCHD Transcoder highly recommended.
It converts AVCHD after the DVCProHD with my editing system is very clear.
This transcode remains, however (according to description) subject to only files which synonymous with a HMC151 were recorded.
The disadvantage is synonymous nor the size of the files to a multiple increase.
Achso the transcoder available free on the Panasonic website ..

Steffen

So if AVCHD, then only high anyway. I learn about this when I read your posts here. But yes, I do not want to CS4 or Edius synonymous "need". Or is there simply not affordable alternatives for I?
Antwort von WoWu:
Try TMPGen Pegasys Xpress 4.5.x
I do not now. whether the final version, but a year ago we have already AVC-intra 100 files in RGB transparent changed.
At that time, dominated the program (4.0.x) has AVC-I. I just do not know whether it works the other way around synonymous. Perhaps the so someone verify that the latest version of the program has.
What I s.der HMC-150 can only really a pity is that since only Panasonic AVCHD uses AVC and not at least 50 class-I has taken. But perhaps want to still a further intermediate step open.
Now probably jump right back someone from the bush and complains that I only ever do anything bad ... but it is not so.
I think the Camera synonymous quite good and it is the step in the right direction. Just a next step would have been even more beautiful.
@ SteffenUp
If you are looking for DVCProHD transkodierst unfortunately you lose quality.
I can step AVC-I only recommend it because the same qualities (tools) to apply.
Antwort von SteffenUp:
Hello!
@ Wolfgang,
Thanks for the tip! Since I will probably need to make smart times with the inexpensive and simple means my data after AVC-I can transcode.
The purchase of an additional fee program comes first with me not in the bag! (yes I've just ordered AdobeProductionPremiumCS4)
What is it with the finishing of AVC-I in Premiere and After Effects from?
I believe Panasonic has the right step.
For people like me who often synonymous times longer shoot things, it is a relief in a cost-effective Flash memory to write!
For AVC-I is indeed in the house then provides Panasonic P2 back on set.
And since we would be back, 2500Eur for 1h Recording ...

Absolutely d'accord, but if the 150 AVC-I would get, the 170 would probably be very difficult to sell have been. What one hears it, is this duo, but actually in the foreseeable future to expand a trio - with a camera handle, then the AVC-I, but unfortunately at P2, will record.

@ WoWu
I have TMPGEnc XPress 4.6.3.268, looking but not quite through. Can you help me again because of AVC-I.
As an output format, I can select between ISO MPEG-4 and MPEG-4 AVC (both MainConcept). I assume, AVC is the right place.
But now ....
Output container type: Normal or ISMA compatible (Portable game console, iPod video and 3GPP are probably not in question)
Profiles: Baseline, Main and High (I would choose high times)
Level: Automatic (Level 4.1 and less), Level 1 to Level 5.1 (what?)
Rate control mode: 1pass constant 1pass variable, constant 1pass quantization, 2pass constant, variable 2pass (what?)
Average / maximum bitrate in kb / s (what?)
Motion search range: (how much?)
Buffer bitrate in kbits (how much?)
Video system: I would either choose automatic or PAL (ev Undefined?)
Detect scene change: (yes or no?)
GOP length (how much?)
B frame count: (how much?)
Reference frame count: (how much?)
Quantization: I Picture: (what?), P Picture: (how much?), B Picture: (what?)
Entropy coding mode: CAVLC or CABAC?
Motion estimation subpel mode: pixel, half pixel, quarter pixel (what?)
Audio Encode type: AAC is on and can not be changed
Audio sampling rate: 44.1 KHz or 48KHz (has other but I would take 48 times)
Channel audio mode: stereo s.ehesten (Monaural would be available)
Audio bitrate in kb / s (what?)
MPEG Audio Version: MPEG-4 (ISO / IEC 14496-3) can not otherwise choose
Audio Object type: Low Complexity and Main (which?)
Audio output format: Raw or With ADTS headers (which?)
Or is that everything is no AVC-I? I know that, unfortunately, still not so good.
