I have just started to take video using GX1 after 1 year of still pictures. I have zero clue, so, some tips and answers to dummy's questions here are most welcomed - 1. Camera shake, I noticed that there are very jarring shake when I walk and shoot at the same time. (I used 45mm and 20mm lens). Any tips to minimize that? Is there any DIY solution such as making myself a bean bag or something like that to hold the camera while walking and shooting? 2. Whats the best way to selectively change focus when I shoot? 3. I had read that we should stick to a camera's native ISO. Is GX1's native ISO 160 - 320 - 640 - 1250 etc..? If we choose ISO value in between above mentioned values, we end up with poor noisy video? 4. Any one has a link to some useful Photoshop video editing tutorials? 5. Shutter speed - How does shutter speed affect video recording? I understand you need high shutter speed for slow motion video? By the way how do you capture slow motion video? 6. MP4 vs AVHC (or something like that) - MP4 is great for computer viewing while AVHC is great for viewing on TV screen? Why is that so? Is that all about MP4 vs AVHC format?
