GH3 Please help me understand Slo Mo on the GH3

Yes we saw that as well with the AF100 that AVCHD masks noise of the sensor. Several people reported this by testing the recording AVCHD internal versus external recording

So it is not that the high bit rate codecs create noise but instead AVCHD smooths noise as to not overwhelm the codec. This minor diffrence noise can be easily taken out in post via neat video and if you plan to spend any time in post it would be advised to use the high bit rate codecs as they allow for greater: color correction and pushing of footage.
 
Just to add my 2c, I always shoot 60p and slow down in post. At first with my Gh2 I used the in can slowmo, but there were two rare occasions that after I filmed a clip I really wished I had it at normal speed and with sound. You can aways speed the clip back up when you record slowmo in cam, but you can't get the sound back.

In a NLE, I can slow a 60P clip down anywhere between 40% and 100% of the original speed and get a nice, smooth effect. With the in-camera mode, you have lost the additional frame information and are stuck with whatever speed you shot it at.

Not sure I understand. We re-time slowmo regularly.

For those of you shooting in 60fps for slo-mo, can you please walk me through the work needed in post? Preferably in Premiere.
For examply, I usually shoot at 30fps. Does this mean I can simply import the 60fps clip into my timeline of 30fps clips and reduce the speed by x%? Or, will Premiere
reduce it by 50% automatically?

Or, are there other steps I am missing altogether?
 
@Ianscreations Premiere does not reduce the speed by 50% automatically. By default it tries to keep the footage at the speed specified in the clip and just uses the approach specified by default (interpolation or frame-blending, etc.) to try and make the footage match the frame rate you are using.

You want to change the playback rate to be correct for the slow-motion (in your case 50% speed or playback rate 0.500 depending on the NLE) and then make sure that the program isn't trying to create new frames.

In Sony Vegas you would click the clip on the timeline, select properties, disable resampling and set the playback rate to 0.500. I don't remember what the equivalent is in Adobe Premiere off the top of my head.
