Most AVCHD cameras will claim full 1080, and some will claim 1080p output. They are all recording as a 1080i frame , and converting to 1080p when using the hdmi output. (My HDV equipment does the same , sends it to the tv as a 1080p signal over hdmi) The resolution is 1920x1080, so technically this would be a slightly sharper picture than the 1440x1080 that HDV records.
My JVC camera has 4 compression settings. 5meg, 12 meg, 15 meg and a whopping 24 meg.
The 3 lower bit rates are directly compatable with the AVCHD standard for optical disks, so disks made can directly be played on bluray players. The 24 meg format is over the spec for AVCHD, and can only be burned to real BDR disks, or transcoded to a lower bitrate for recording on conventional DVD-R media with compatability with blu ray players.
Most editing software these days will handle both HDV and AVCHD formats.
When I have done side by side tests comparing my AVCHD camera to my HDV cameras, I am hard pressed to see any real difference. They are very good. When it comes to editing, the AVC format is moch more finicky to work with. If is it a single camera personal video, then I may shoot it on my flash memory camera just because it is convient. If I am shooting anything 2 camera, or any commercial shoots that I know I am going to need to edit, then I shoot HDV, and leave the AVC camera at home. Why? The editing process for HDV is no different than for shooting DV. I plug the player into my old tired work station , and fire up Adobe Premiere pro, and capture my clips no differently than working with DV. In the background Cineform is making I frame versions of the IPB stream . Now I have frame accurate files that I can edit, in real time just like working with standard definition .
It is fast , accurate and has an unbeatable picture.
All of the consumer editing programs I have tried for AVCHD are so bloody limited that someone with my background has a real hard time figuring our how to so the simplest things. Once the project is edited I can output in whatever format I want. I can send it back to HDV which is whet I archive my material in, and I can also output an SD version for DVD distribution and AVCHD version for distribution on conventional DVDs that play i9n HD on bluray players.
@ 10 megs 60 minutes will go on a 4.7g disk . 2 hours will fit nicely on a dual layer disk.
Rendering takes about 3 hours for a 60 minute production shot and edited in HDV.
Now, if I had 60 minutes shot on AVCHD, take that time and multiply it by 3 and you get an idea how long it takes to render out from MPG4.
Basic cuts takes less time, but if there are transitions and effects , this really drags the system down to a crawl.
Another thing , I just happen to like tape. It is cheap, and you always have a reliable backup.
I keep all my master tapes just incase I ever need to go back and rework something, or need a shot that I know I have. Digital media is far too expensive to store (SD cards) and DVD's and hard drives are not reliable for long time storage . DVDs are easily damages by exposure to light, hard drives, lets not go there. Tape is reliable. I have tapes I recorded in the early 80's and they all play fine.
I also forgot to point out that due to the compression, h.264 video tends to degrade quickly with multi pass editing, or re-encoding
HDV since the compression is much lower stands up much better during the editing process.
" Today reading the fine print in a Sony print ad, I believe it said that HD camcorders record in AVCHD format and they cannot be played in regular DVD players, only Blue Ray or Playstation , or PCs with certain software.
I do not have a Blue Ray and I want to be able to make copies of the DVDs I burn to give them to family to be played on regular DVD players."
For the most part ALL consumer hard disc drive (HDD) and flash memory high definition camcorders use AVCHD compression.
When you import the AVCHD/MTS file to your video editor , the first step is to decompress that video so the editor can deal with it - the same happens with HDV. After you finish editing you have more than one rendering step - depending on the playback method and mechanism.
1) If you are outputting to a blank DVD you can save as an AVCHD - h.264 data file and burn that to a single layer, double layer or BluRay blank disc - which you use depends on what your computer is capable of burning to... Burning this type of data file can only be played back using a BluRay player - or your computer.
2) If you use a DVD authoring tool (like WinDVD or iDVD) it will downsample the video to standard definition playable in a regular DVD. The DVD authoring tool will create the required VOB video format that regular DVD players can deal with.
3) If you render a "standard definition data file" from your computer to a computer readable file (MOV or AVI), it is downsampled - and not readable in a regular DVD, but computer-readable - this can be AVI, WMV, MOV or MP4 format - among others .
4) If you render to a high definition data file, similar to #3, it cannot be read by the regular DVD player, but uploading to YouTube or Vimeo will allow high definition playback online. h.264 (MOV or AVI) is common.
Yes, BluRay readable AVCHD/MTS files can also be played on a PS3.
Optical zoom has little to do with a camcorder's "video quality ".
You do not need a BluRay burner and you do not need a BluRay Player - unless you are wanting to NOT edit and merely copy AVCHD/MTS files from the camcorder source hard drive to a blank (soon to be) data DVD... OR if the video segments are too long to fit on a single layer (4.7 gig) or double layer (8.5 gig blank. BluRay blanks star at 25 gig. High definition video is about 4x more than standard definition video.
While we're at it, the software included in the box with any camcorder is useless and should not be installed... it is unnecessary. Windows MovieMaker cannot deal with AVCHD; only under certain conditions can deal with HDV... Apple iMovie '08 or newer is required to deal with AVCHD running on an Intel Mac. In the Windows/Vista environment, Sony Vegas and Adobe Premiere float to the top - with Macintosh, iMovie '08 or newer or the current versions of FinalCut make the grade for AVCHD - iMovie and Final Cut have been dealing with HDV for years .
Due to lowest $/gig, long archive shelf life, and MANY other reasons , I suggest you skip hard drive camcorders... miniDV tape continues to be king - whether you want it to or not and the process flow for HDD and flash memory continues to be challenging - no matter what the manufacturers want you to think.
HDV is clearly better than AVCHD and its also a considerable amount cheaper. The only reason it seems that AVCHD triumphed over HDV was due to the fact that they could be manufactured for less, so therefore you buy them for less. Technically speaking HDV records in a unique recording formant however these formats can be changed without any quality loss by using VLC. Its almost tragic how there are no more consumer HDV's being made any-more, however they can be bought for less online. Remember HDV is still used by professionals today and has been for years so if your having trouble deciding defiantly go for HDV.

How to write a Design Report

How to Write a Design Report Summary A design report is the written record of the project and generally is the only record that lives once the design team disbands at the end of the project. The report has three sections. The first section describes the problem that was being solved and provides the background to the design. The second section describes the design and the third section evaluates how well the design worked by comparing its performance to the design requirements. The report starts with a short executive summary that contains a synopsis of the three sections. The body of the report is relatively short. Appendices to the report contain supporting information with the details needed by a reader who wishes to fully understand the design. While this document describes the general content and organization of a design report, some of the specifics (section headings, length, and format) may be determined by your project client. Before You Begin Some basics that you need to und

2-stroke tuners handbook tuners

Two-Stroke TUNER’S HANDBOOK By Gordon Jennings Illustrations by the author Copyright © 1973 by Gordon Jennings Compiled for reprint © 2007 by Ken i PREFACE Many years have passed since Gordon Jennings first published this manual. Its 2007 and although there have been huge technological changes the basics are still the basics. There is a huge interest in vintage snowmobiles and their “simple” two stroke power plants of yesteryear. There is a wealth of knowledge contained in this manual. Let’s journey back to 1973 and read the book that was the two stroke bible of that era. Decades have passed since I hung around with John and Jim. John and I worked for the same corporation and I found a 500 triple Kawasaki for him at a reasonable price. He converted it into a drag bike, modified the engine completely and added mikuni carbs and tuned pipes. John borrowed Jim’s cop
