Does your video use a VARIABLE Frame Rate or a Constant Frame Rate?
hhow do I know if my video uses a variable or constant frame rate. And how what are codec details of a file?
data rate- 6303 kbps
total bitrate- 6471 Kbps
frame rate - 20 frames per second
bit rate- 168 Kbps
channels 2 stereo
audio sample rate- 44 kHz
OK... back to my 1st question... where did you get the video... exactly what brand/model camera?

>how do I know
You go back to the second link I provided and install the program for your operating system and use that program to analyze your video
>frame rate - 20 frames per second
That is an odd frame rate, so still waiting for the answer to my 1st question
how do I know if my video uses a variable or constant frame rate
The sure way to know if your video was recorded with a variable frame rate is to look at the video properties readout in MediaInfo (Tree view). If the video was recorded with a variable frame rate, you will see 3 frames rates
minimum frame rate
maximum frame rate
Have you gotten to John's suggestion regarding using MediaInfo to get video properties information?
A typical video readout from MediaInfo (Tree View) will look like the following
(following is for a video recorded with my iPod which uses variable frame rate...note the 3 frame rates under video properties)
sorry for the delayed response. I didnt have internet for a long time so I was not able to respond. I believe this is what you were looking for. What do you believe is the next step from here? John T Smith
Take your 1280 x 720 @ variable frame rates into HandBrake to get the H.264.mp4 version 1280 x 720 @ constant 30 progressive frames per second.
1. Download and install the program
2. Open HandBrake, click on Source/File to browse to and import your file into the project.
a. Where is shows "Chapters", I usually change that to "seconds"
b. Browse to and set the Save Location for the file to be generated.
c. Output Setting Container = MP4
d. Look at the Picture Tab setup. You should see 1280 in the Width field...leave everything as you see it, and click on the Video Tab.
e. Under the Video Tab
Video Codec = H.264 (X264)
Set Framerate (FPS) = 30
And, be sure to have the dot next to Constant Framerate
Then click the Green Start button at the top left of the workspace.
Watch the progress bar at the bottom left of the workspace for the Queue Finished message. You are done.
Please let us know the outcome as your schedule permits.
I just ran into this same problem and this was extremely helpful and easy. Thank you!
