AVCHD sucks!

Got my hmc upgrade from my old DVX, lots of things I like, some I don't , but god is there ever a lot of macroblocks. even on the highest setting.

if you want your movies to look like something you DOWNLOADED ON A TORRENT, get a hmc150:crybaby:


Ok, it's not that bad, but seriously 24mbps is not enough for 720 or 1080, I don't care how good they say h.264's compression is, you can't get something from nothing, WHAT IS THIS WORLD COMING TO!?!:Drogar-Kriz(DBG):

anyone else have experience with this?

I wish I could select 30 or 40 mbps,
 
Funny, I shot a short film recently with three cameras: A Varicam, HVX200, and an HMC 150, all were shooting 720p @ 23.98 and after some very good color correction you would be hard pressed to tell most of them apart. Granted the HVX and the HMC had much deeper depth of field, but from my experience, AVCHD (or more specifically AVCCAM in Panasonic's case) was no problem for me. YMMV.

sorry I was not putting down the HMC150, but the avchd format in general, or the shotty bitrate

blu-ray for instance is 1080 and H264 as well, the difference is it's 40mbps not 24
 
We mastered our film out to HD and the Blu Ray's we made looked phenomenal, even with our "lowly" 720p cameras, one of which was shooting in AVCHD. Some turbocharged 4 cylinder cars can outperform 8 cylinder cars.... just saying, are numbers everything? How are the low bit rates failing you?

well i know from 15 years experience compressing videos that, new compressions help but are still lossy, in the end you need to use the bits.

again if blueray is 1920x1080 30fps h.264 and 40 mbps
I'd like to see the HMC150s 1920x1080 30pfs h.264 and 40mbps as well, not 24, i can clearly see the difference.
 
My experience is that HMC-150 looks identical to hpx-170, and will cut in closely to any panasonic p2 camera.
 
I dont beloeve that screengrab
Post a real raw footage of the mts.
Ive used the avchd a hindred tomes with no problem ever specially on that kindof simple scene
 
unless there is something I'm doing wrong, (or something wrong with my camera)

that screenshot is the HMC on a tripod about 5 feet from subject, stationary, with 3 diffuser lights. detail set to "0" cinelike gamma ect.. fairly common settings, and PH(highest bit rate) 1080 24P,
 
What Scene File are you using? The first footage I shot on my HMC150 at stock auto everything was incredibly underwhelming. I have played with it since and gotten some pretty good results.

I did the factory reset bit and I don't ever use the default scene file.

I do find it kind of strange that it seems to be a common experience for someone to open up a new HMC150, and of course the first thing they want to do is shoot some test footage, and the footage they get looks like turd.

To be honest, it is kind of scary, and I think Panasonic should set the default to be sort of sweet looking so we can feel good right away!:2vrolijk_08:

Just play with the camera, read up, and you will get some good results.

I would never use a default as well,

I believe it's all flat with cine v, and perhaps chroma at -2 and ped -20

thing is a scene file is not going to have a huge impact on macro blocks anyway, thats for the bitrate to decide.
 
The settings on the HMC make a massive difference to the footage captured and TBH I've not yet found one I'm totally happy with, but for normal viewing the HMC has produced some amazing (and very sharp) footage. OTOH it's also produced some crap. It's how you shoot.

Now, I notice you used green screen as an example. 4:2:0 is not ideal for green screen. If this is what you are shooting then a 4:2:2 capable camera should have been your first choice, or at least record from the HDMI (which is 4:2:2) instead of going via AVCHD.

The HMC is a great workhorse camera but clearly it's never going to compete with a RED ;)

Not to hijack this thread but I am actually doing a green screen shoot tonight and your comment of 4:2:0 just put the thought in my head. I know you mentioned this, but the HDMI out of the 150 4:2:2? In other words, rather than shooting to memory card, if I take the HDMI out of the camera into my black magic intensity card in my mac pro will it capture 4:2:2?
 
Are you transcoding ¥our footage? Are you trying to edit the raw avchd files? We need more info. I have yet to see any macroblocking from anything I have shot with an HMC.
 
I've seen macro blocking as well when trying to edit raw footage.

Never on a transcode to an intermediate codec however.
 
I have to agree with David S. trying to edit raw avchd footage on a low spec computer will probably cause macroblocking. Best to transcode to an intermediate format to edit or make surr your system is up to par to handle the codec.
