  • Here is some test footages made with GOP1 settings. May be it will be interesting for somebody.
  • Was messing around with low GOP settings and rig's GOP1 would crash constantly on my Transcend 16gb Class 10. I loaded This patch and changed Gop to 6 and it worked much better, didn't crash once in similar shots. Set it to GOP4 far so good.

    All I did was change 1080/25p to GOP5, 24p to GOP4, and under AVCHD Research I dropped the audio buffer to idea why...and upped the video buffer to max, 84. Works so far, but only done very basic shots. But it recorded super over exposed and in pure darkness it recorded 3 times as long as the GOP1 patch.

    EDIT: Just did a quick test to see how long it would record a all black scene and it went around 7-10 seconds when you start the scene, all black. It also did 7-10 recording a bright all white scene. However, when I started with a standard lit scene then moved to all black it went over 20 seconds before I got cold feet and moved the camera around. And by "This" patch, I mean LPowell's 100 mb Max Latitude patch.

  • remember when this is a new idea - glad someone who is better at these things than me (Nick Driftwood) stepped up to the plate and made it happen.
