Sony just announced the new HXR-NX3 handheld HD camcorder, a pro camcorder that adds W-Fi connectivity and an MP4 recording option to the NXCAM line-up, allowing such functions as using an iOS or Android device to monitor recording and control zoom, iris, and touch auto-focus remotely. The HXR-NX3 combines leading lens, sensor and LSI technology to achieve impressive and stunning video quality. It records in the AVCHD 2.0 format at up to 1080p/60, with 60i and 24p modes included for direct playback on Blu-ray players. 1080p/30 and 720p60 are also available. The dual SD slots can be used in relay or simultaneous recording modes when recording AVCHD (but not MP4), and a clean HDMI output has the capability of recording uncompressed 8-bit 4:2:2 images externally.
While the problem users find is that 1080P AVCHD 2.0 MTS/M2TS files are not favorable for Avid Media Composer (including Avid Media Composer 6.5). Even you sucessfully load NX3 1080P AVCHD 2.0 to Avid, it always need a long time for rendering. As we know, Avid’s most friendly video format is DNxHD MOV. DNxHD is a lossy high-definition video post-production codec intended to be usable as both an intermediate format suitable for use while editing. It's better to encode AVCHD 2.0 to Avid DNxHD HD codec, which delivers both efficiency and quality without compromises. Here introduces Aunsoft Video Converter for Mac.
