"One of the biggest issues concerning UHD/4K is how it will be encoded/compressed and what bit rate will be required to convey a high-quality image. As I've written before, everyone at NAB 2014 seems to have settled on H.265 (aka HEVC or High-Efficiency Video Coding) as the codec of choice for UHD/4K. HEVC is said to offer up to 50 percent greater efficiency than H.264 (aka AVC or Advanced Video Coding), which is often used for high-def content, and even greater gains in efficiency over MPEG-2.   So I was particularly interested in a presentation called "Bit Rate Requirements for HEVC: Comparing H.265, H.264, and MPEG-2" by John Pallett, Director of Product Marketing for Enterprise Products at Telestream, a company that provides video capture, encoding, transcoding, and network-based delivery. The testing he discussed was based on SD and HD content, not UHD, but the findings should apply similarly."

Useful utility to rotate those videos you created with your phone and you recorded sideways.

"VLC is a media player that will play just about any video or audio file that you can find. You don't need to look for any plugins, codecs, or extensions - everything you need is built right in, so that it will play anything right out of the box."

"I've got a Panasonic HC-V750 camcorder which supports AVCHD and MP4. The highest quality AVCHD settings are called "1080/60p", while the highest quality MP4 settings are called "1080/50M" (also at 60p). Both are 1920x1080 full HD resolution.   When I check out some sample files recorded in those 2 formats with MediaInfo, I see the AVCHD bitrate is variable and seems to be in the 22.8 - 25.0 mbps range, while the MP4 bitrate is close to the advertised "50M" at a variable 45.4 - 49.2 mbps.   So, although I know the answer is a bit subjective, I am interested in which format people think has better video quality.  By bitrate and file size alone, I would be inclined to say MP4 in this scenario.  But the instruction manual implies that the AVCHD is better quality.   FYI: on the audio side, the AVCHD has AC3 384 kbps 6 channel audio, while the MP4 has AAC 128 kbps 2 channel, so the AVCHD AC3 audio clearly seems superior."

Very useful tools for batch processing of graphic images. I've used the PhotoResizer application - very handy. Downloaded the RealWorld Photos application that permits batch processing of simple things, such as watermarking, removing red eye, etc. No loss to original file.
