Using the HMC152 with Premiere Pro CS4.1

Just a question from a newbee..

As I see it I get two main options with this camera, to record in 50p (720) or in 25p (1080) mode.

My confusion is that I though that I can record in 50i (1080) mode, however when I bring it into Premiere Pro CS4.1 it plays it back as 25p (or 25 frames per second) rather than the 50i.

As a result, I believe, the playback is a little jerky for relatively fast pans and quick movements. However if I play it back on a tv with 50i, then it is much smother.

Is there a way to play it back on the computer so it looks as smooth as it does on the tv?

Am I missing something?

Thanks in advance.
 
I'm not certain that I'm following your question... but here are a few thoughts that may or may not be related.

First, regarding Premiere, you need to make sure you've got the right Sequence settings. Meaning, when you create a new Sequence, you're presented with a range of AVCHD presets -- including 1080 and 720 formats. Get this part right and you should be fine.

Regarding playback in Premiere -- when you right click on the video window you are presented with playback quality choices. From memory -- I think they're "best," "draft," and "auto." "Best," attempts quality, "draft," improves performance (the funky stuff you see doesn't show up in what you send to Adobe Media Encoder), and "auto" means the program attempts to decide if your computer sucks -- or not.

Regarding playback on the PC -- look into "CoreAVC" -- a codec you can buy (I think $14) that allows you to play AVCHD in Windows Media Player at full resolution with the ease of any other video format of the past.

For Premiere Pro resources look to lynda.com and "Total Training." For HMC resources buy Barry Green's book on the HMC.

Good luck!
 
Thanks AGMedia for your reply and good advice.

I have played around with the video window to alter playback quality. I am more interested in the playback frames per second. For instance, 50i frames per second (interlaced), looks smoother than 25 frames per second (progressive). I am wondering then; why when I shoose the correct settings in Premiere Pro for 50i, it presents a timeline of 25 frames per second - which will result in a jerky movement and film-like appearance.

Of course it makes sense to me that a non-linear editing program cannot playback each interlaced frame, however when I play back at normal speed, the footage is "jerky" in appearance especially compared to when I play back on a TV with 50i or using another media player.

Is this your experience also? Can you check?
 
Interlaced does look smoother than progressive frames in most forms of playback. However, editing and effects on interlaced footage has issues. From the perspective of the producer -- you -- there are advantages to shooting progressive. Search this forum and look online regarding this topic -- it's a vast, vast discussion.

Regarding your specific issue with Premiere -- I don't understand -- because I've never had this problem. My best recommendation is to contact Adobe technical support.

Playback in Premiere may seem "jerky" due to a range of issues -- many of which may relate to your hardware -- meaning your computer. My computers are newer with lots of memory, etc. -- so, no, I don't have these problems. Playback in Premiere isn't perfect, but it's not more awful than I'd expect.

I'm sorry I can't be more helpful. Regarding your specific issue with frame rates in sequences not matching up to your sequence settings -- my best recommendation is to contact Adobe Technical Support. Regarding the advantages/disadvantages of shooting progressive or interlaced from the perspective of the producer -- search this forum and the web -- a vast discussion awaits you (resulting in the conclusion that you should be shooting progressive even if you intend to encode to interlaced).

Good luck!
 
So, I will be editing on a new MacBook Pro, the 3.06 Ghz processor, 8 GB RAM, and the 7200 rpm hard drive. It will have Snow Leopard. I want to use Premiere CS4 and After Effects CS4 for editing/effects.

I am considering the HMC150, and I was just wondering what is suggested as best practice in terms of AVCHD workflow? Do most of you suggest transcoding the avchd files into something else with a third-party program such as NeoHD before going into the Adobe environment? How is it editing with the raw files, treating them in After Effects, then editing in Premiere?

Thanks in advance for any advice.

You would be better off transcoding into a self contain frame... native editing will be very slow and almost impossible on MBP, specially if using AE or applying any kind of Filters or Color Correction!

I'm not using premier, i have FCP7 running on MBP 17" 2.4! and transcoding is fast and yields the best results at the end.
