![]() The magic to fitting 3 hours of video on a 4. You don't want to get much lower than a quality setting of 70. In thisĪrea every 5 quality units that you go down is about the same as decreasing Twice as fast than dvd2one, it uses the M2VRequantiser engine (with kind. If the videos don't come out small enough try a quality of 80 or 75. The encoding will take place in constant quality and variable bitrate (instead. Making the video much easier to compress and removing the time-varyingĬompression distortions of the DV material you started out with. The noise reduction serves the dual purpose of ![]() To increase the noise reduction until the background noise/pixel flutter isĪbout half what it used to be. If your video camera has much more noise than a VX2000 you might want On a side note, you have specifically asked about the global variables, but placing constants and the like into namespaces are always a good way to avoid name clashes etc. const double pi 3.1415, const std::sizet answer 42 etc. It takes a long time but it sure is nice in the end. This (the const int i 1234 ) has a general use case for program wide constant values, e.g. If you have a 2.4 Ghz PIV expect to spend 25 hours compressing your video In the equation, \ (10x y25, 10x\) and \ (y\) are variables. Constants are usually mentioned in numbers. Variables are usually mentioned in letters and symbols. Use the maximum quality motion estimation. On the other hand, constants do not change their value with the situation. Set the max bitrate to 7500 kbpsĪnd the minimum to 2000. Use noise reduction with a setting of 12-1-12Īnd do a CQ encode at a quality factor of 85. The value of x, on the other hand, is independent of the values y, a, and b. In this equation the y variable is dependent on the values of x, a, and b. In a program, we differentiate a variable from a constant by using the naming conventions. These are constants that help define the relationship between the two variables. Using TMPG via Satish's frameserver should allow you to fit up to aboutĢ.5 hours of good video on a disk. In python, variables and constants are not differentiated from each other by the interpreter. If you're lucky and have a still shot or fade to black or white, you might even split the timeline there, do a slight time compression, render that portion, cut/merge it using TMPEnc, optionally re-rendering the audio track. I've seen mpg2 files with vbr rates of 2.4 M, 1.6 M,
