Hey everyone. I did some hacked AVCHD tests with my Patriot 16GB Class 10 SDHC card and my GH-13 and shot two clips of static "leafy tree" footage on a tripod:
1. "B" settings with Native 24p checked
2. "D" settings without Native 24p checked
After watching the footage on my 47" 1080p LCD flat screen and comparing the two side by side using Windows Media Player 11 and Windows Media Player Classic, both using the K-lite codec pack, I have come to the conclusion, according to what my eyes see, that the "D" settings without Native 24p looked much better.I noticed what looked like mud and other compression artifacts on the "B" settings footage that didn't show up on the "D" settings footage. Of course, the codec could be partly to blame for that. Most likely the "D" settings footage looked better because of the higher bit rate.
So, I've decided to shoot without Native 24p AVCHD from here on out. My question is, what are the highest tested bit rates for a "non-native" 24p hack? Has anyone tested 80k and above? Or would that be pushing the GH-13 too hard? I checked out the GH-13 test spreadsheet and it looks like nobody went higher than 70k on the AVCHD 1080 24p Limiting Video Bitrate Adjustment. Does anything higher than 70k always freeze up the camera? Thanks.
