Frame Rate Dilemma

With the original method, there was no way to change the frame rate, except between the default three settings. That’s to say, 6, 10 or 15 frames per second. However, with the new method, you are now able to choose between 10, 12, 15, 24, 25, 30. The reasons for the new additions are as follows:

§ 30fps – to allow for full playback of 29.97fps (NTSC standard) and 30fps clips.

§ 25fps – to allow for full playback of 25fps (PAL standard) clips.

§ 24fps – to allow for full playback of 23.98 fps (NTSC Film Standard) clips

In order to use these settings, you will need to make the following changes to the encoding process:

4:3 Source

§ Set the frame rate in WinAvi to the appropriate rate.

Widescreen Source

§ Set the frame rate in TMPGEnc to the appropriate rate. (It should set itself automatically to the existing frame rate of the file)

DVD

§ Identify the frame rate of the DVD in DVD2AVI and set the frame rate in TMPGEnc.

§ Set the frame rate in MovieStage. (The clips are broadcast at 30fps)

MovieStage

§ Set the required frame rate. For 24-30fps, you will need to set the Output Format as Sharp 902SH (High Settings) and select your frame rate as appropriate.

The dilemma here is that the higher frame rates do not necessarily produce better results. While the picture does see somewhat smoother, it skips at intervals. This is evident in the 25fps Preview clip, where the Millennium Falcon freezes as it is racing down the tunnel. However, it is something that each individual needs to test and decides for themselves. It is definitely a matter of personal preference, but maybe, if you are encoding a low movement clip (something like The O.C.), then perhaps the higher frame rate would work.. However, it is important to consider that by increasing the frame rate, you are effectively reducing the quality of the image, as you are producing more frames for the 500kb data rate to compensate for.

As I said, I think that it is something that everyone should try for themselves, if interested. I would be interested to hear your comments on the matter, so feel free to contact me!
