Q: I am currently working on a big project with Windows Movie Maker. Many of the files that I'm working with have unusual frame rates (30.12, 30.35, 30.11, etc). After I put my movie together and publish it, the audio and video are often out of sync on the parts from the movies with the weird frame rates. I've tried adjusting the frame rates with Virtualdub, but that doesn't work successfully with every file. How to fix this problem?

Q: I recorded some videos in .mp4 format, but when I tended to stream the videos through the USB port on my LG smart TV, it refused to play them. I'm sure the videos are all encoded correctly and being in LG TV supported video formats (H.264/AAC). Does anyone know what's going on?

Q: I have a problem uploading and playing this video on a web portal, some slides consistently stutter or display distortions. And I suspect the problem is prompted by the strange frame rate of 30.302. Whatever does it mean - 30.302 frames per second?

What's Frame Rate?

Frame rate, generally speaking, is how many frames of an animation are appearing on your screen per second. It is measured in frames per second (aka FPS). The term applies equally to film and video cameras, computer graphics, and motion capture systems.

For video frame rate, a low frame rate will create a flickering effect, and looks a bit choppy and strobe. However, a higher frame rate will makes video very large at a constant resolution, which is probably not accepted by most devices for playback. You know, a video with a higher frame rate may be refused and unplayable since some devices only accept a certain standard value of frame rate. Actually, there are some common-used main frame rate standards for video: 23.97 FPS, 24 FPS, 25 FPS, 29.97 FPS and 30 FPS.
