Hi, I have Canon HD camcorder, when i import to my PC it is .mts file. I edit my .mts file using X4 Video Studio, Now i want to make DVD, which format i should select for best result with compress size ?
I tried DVD 4:3 then my video quality is goes down, and if i select DVD 16:9 then file size is increase much so please help me which format i should select to keep file size low or same with same video quality.
Thank you

Re: .mts file conversion problem
Your camera evidently films in AVCHD format (which uses the .mts or .m2ts format). That is high definition, high quality and highly compressed video in mpeg-4 format. It is meant to produce high quality video in a relatively small size. It usually films with a maximum bitrate of anything between 16,000 and 27,000 kbps.
A standard definition DVD, which is what you are wanting to make, uses less compressed, standard definition mpeg-2. Its lower compression means a larger file is produced. It also uses a much lower bitrate than your AVCHD -- anything between 4,000 and 9,000 kbps. As a result of this, the video quality will be much less good than your original video.
Your original video is in 16:9 format as well, so you must use that frame format throughout your project.
The conclusion of all this is that you have to convert your AVCHD mpeg-4 to standard definition mpeg-2. If your project is one hour long or less, then you would simply choose Share > Create Video File > DVD. This will convert the original video and make the DVD-compatible mpeg-2. It will probably take some time to process. But you can then use your new mpeg-2 to burn to a standard definition disc. It will use a high quality (for standard definition) bitrate of 8000 kbps. But because it is standard definition, the final quality will never be as good as the AVCHD original. If your project is longer than 1 hour, you would need to choose Share > Create Video File > Custom, and then change the bitrate downwards to be able to fit more video on the disc. As a guide, 6000 kbps will allow you to burn 90 minutes; and 4000 kbps will allow two hours. In all cases, if you use Dolby Digital audio, you will be able to fit another 10 minutes or so of video onto the DVD.
The only way to keep the high quality of the original video, however, is to burn either a Blu-Ray disc or what is called an AVCHD "hybrid" disc which has a Blu-Ray file structure but can be burned to a standard definition DVD disc. Both Blu-Ray and hybrid discs can only be played in a Blu-Ray player. And a hybrid disc using a bitrate of 18 Mbps will only allow about 20 minutes of video to be burned to a single layer DVD.
