GH13 Newb alert: GH13 Premiere workflow questions

[DrewC]

Hi guys, I'm new to the video scene, Been a still photographer for quite a while (feel free to check out my site if you'd like ( http://www.drewcarlsonphotography.com ))

I've recently acquired a GH13 and am editing on a 2009 2.8ghz Macbook Pro 4gb Ram with Premiere Pro CS5

I'm terribly confused on the workflow side of video. Currently I'm dropping the lone .mts files into my premiere project, but I suspect that's the wrong way of doing it. I'm shooting 1080/24 and when I export at 24fps it gets extremely jerky, like I'm watching an earthquake happen.

Instead I use the 30fps Vimeo HD preset and that seems to work fine, but why can't I seem to export in 24fps?

Do I need to be importing my footage in a different manner? Do I need to be running it through some intermediate software? (I keep looking for answers on the forums and can't come to any conclusions because the verbiage is foreign to me, I don't know what pull-down, b-frames, etc... even mean!) I really am trying to take it all in, but it's a bit overwhelming.

Any advice would be greatly appreciated. Thanks!

FWIW: Here's some test footage using the Vimeo HD preset (720/30) http://vimeo.com/22679512 It's a little jerky still, but SOME of it can be attributed to a sticky slider and poor technique.

if you import your footage into the project window as normal, instead of creating a comp to match you should be able to drag a bit of footage onto the "new comp" icon at the bottom on the project window, this will create a comp that exactly matches the footage.

the stagger you mention in the clip you upload... i think all DSLR video cams have this effect, not sure why.

theres a hollywood rule you should check out, cant remember it off hand but it is something like this... if you are panning 180 degrees it should take no shorter than 30 seconds to complete the pan.

your panning is super fast and if you were shooting anything i doubt you would use a pan of that speed, either go slow (30 second rule) or whip pans when you pan from static to static shot with a quick whip!

There are a couple of thoughts that I have... I have the GH1 so I can only record 24p in the telecined 60i mode. I just verified yet again... that when I do the following the reverse telecine process is 'automatically' performed.

I have a MTS file 1080p at 24 fps (23...whatever...), which shows 'motion' on every frame... a dog running in the yard...

I simply import that media, create a sequence using the AVCHD 1080 24p options. I do not 'drag and drop' on the 'new' icon in the browser window, as I just verified that procedure, and it does not do the 'automagic' reverse telecine process. I verified these two claims by stepping frame by frame in the sequences and saw no duplicate frames in the created 24p sequence, but did see repeated frames in the 'drag over the icon' method of creating a sequence.

So, the question here is, are you using the 'native 24p' option of the GH13 setup? If you are still using the telecined 60i mode, you need to make sure you create a sequence manually, drop in your media to get the reverse telecine process to happen.

As a note, I looked at the 'interpret footage', and the 'remove 24p pulldown' is greyed out, which means you can only use the 'automagical' version. In After Effects you can force the 'interpretation' of the media, and CS 5 AE 'does the right thing'...

Ok, once that all has been cleared up, and you are actually dealing with 24p material in your sequence time line... the next area of trouble is when you export...

What are your options and what have you selected for compression, for example are your trying to play 1080x1920 material using say H.264 codec... I can't get that to run smoothly on my laptop... so that could be the problem there.

I don't have time to go through that process right now, but some of the parameters that I'd look at are 'maximum bit rate'... 'older computers'... do not take kindly to very high bit rates... USB disks do not take kindly to high bit rates... You may experiement with say setting the max at 20 Mbits/s or so. and see if that 'plays' better. The problem of course is that when 1080 is compressed to that bit rate there may be other artifacts that come into the evaluation of 'goodness', and so, you may have to either live with those lower bit rate induced artifacts, or just make several versions at different bit rates so that you can play smoothly on your hardware, but others who have better can get better quality...
