How to edit DVD files without any DVD capture / DVD to Video File converter software!
So many times you had a DVD that you needed to make some changes to, however you think that you can’t. So you have wondered, how can I import that file lets say into Premier or Movie Maker and edit it?
Well there are many applications have been developed, that so called “capture DVD” and transfer then to AVI, WMV, MOV, etc. Guess what, you have to pay for them and in reality you don’t need them!
Well, the answer is simple!
The actual video files on DVD have file extension VOB. In reality all it is: mpeg2 encoded video file.
Now to edit that file all you need to do is:
1) Re-name VOB file extension as mpg. Now you have a regular mpg (or mpeg) video file.
2) Now you can import that file and edit it. Most of the video editing software packages will support it (well there are cases then they don’t...but that is another topic)
3) Re-edit the footage
4) Transcode to DVD / Burn DVD
5) You are done!
No extra software solutions are required! Most of them simply try to cash in on non tech customers!
Hope this information helps!
Thanks

| Myth buster about mega pixels and HD cameras. HD vs SD |
|
|
After looking at the numerous postings online and having people complaining about poor quality of their so called HD cameras, I would like to put my input on the subject.
First of all lets get down to the basic: Good picture quality is in essence two main aspects (both video or photo)
1) Number of pixels or image size
2) Quality of the picture or quality of the each individual pixel.
In theory the larger the image size is and the better pixel quality is the better result is. However, what has been happening on the market is: Companies has been advertising high definition cameras at the same time compromising picture quality. So when you film something on a cheap HD hand held camcorder in reality you might end up having video quality less of a quality then a regular pro level standard definition cameras.
To give you an example: most of the phones now advertise excellent picture quality of 5Mp. Have you ever looked at the quality of that pictures or videos taken on that phone? I am sure you did and the result is horrible. Loads of noise, pixels are grainy, etc. In reality the chip or sensor simply can’t handle such high definition image and image size wise is mostly increased on a software side. With the same result you can try and foto-copy company logo and increase the size and print large banner – it won’t work.
What you should really pay attention to is: CHIP! CHIP! And one more time CHIP! Also, the lens is important issue as well. All pro level equipment uses at least 3 chips that captures the image (1 chip per color in RGB mode) As a result, image taken on a older camcorder which is pro or semi pro level will be of a better quality then most so called HD Cameras! If for some reason you need to produce high definition video and don’t have a budget for a decent HD Camera (which are still quite expensive at the moment, starting from £6500) then instead of using cheaper HD domestic handhelds you are better getting a Pro level cam, film in SD, and up-scale to HD on editing side.
At the end of the day, the question you should really ask what is that image or video will be used for. So far, unless you are planning to broadcast something live in HD TV, then most of the time you are still better of with a regular definition using good quality equipment. It’s not all about image size! It’s about the quality of image first of all!
Hope this helps and please feel free to e-mail and ask questions on the subject.
