A Frame Rate Related Question, Weird....

The Winster · Post by **The Winster** » Fri Apr 01, 2005 12:54 pm

I have two vids in wmv format

One is "Linkin Park - Faint", the other is "Evanescence - My Immortal". Both are encoded at 304 kbps.

Now, when I play the video in Winamp 5.0x the "Faint", the average FPS lingers around 12 fps. When I load the wmv in Blaze Media Pro's editor, the FPS is reported as 25.00. Weirdly, when the same vid (the same file) is loaded in TMPGenc for encoding, the source FPS is reported as 30.00 FPS

The samething happens with the Evanescence vid. The only difference is that the average FPS in Winap lingers around 16 fps. TMPGenc and BMP report 30..00 and 25.00 fps respectively.

Can anyone figure out the problem? I want to enode both these videos to a PAL videocd. Since the FPS that the encoders detect are different, woul the end result (the MPG Pal file) encoded by them be different?

I am not so curious about the second question as about the first question. So, if anyone has experienced the same thing or can figure out a theoritical explanation, please reply. I know its not an amv related thread, but still, it is related to encoding, which forms an essential part of the work of the forum visitors...

Many decoders can't play video at the full framerate it was encoded at, so it may display numbers below that of the real framerate. Unfortunately, I can't remember how to check a WMV's real framerate. Try loading it into Windows Media Player 6.5 (mplayer2.exe, located in the WMP Program folder) or Media Player Classic and go to View->Statistics to see what they say the framerate is.

Are you using TMPGEnc's wizard to do this, or the main screen? I've never used the other program, so I don't have any clue about it. TMPGEnc may be hardwired to handle WMV files as 30fps automatically if loaded on the main screen (which means you'd have to click on the 'Settings' button and manually change the framerate to 25), but if you use the wizard and specify PAL under the Video CD section it won't be a problem, because it will change the framerate and frame size to it's proper dimensions for PAL.

I use TMPGenc's Main Screen, and sometimes, if the project is too eay, I use the wizard.

Its the main screen in this case though.

I think the 30FPS stat in TMPGenc might be the destination FPS, so nothing to worry about. I say this, because when you change the FPS of the estination file, this stat changes too.

Thanks for solving my problem.

I cant edit my message, so...

I think the Blaze Media Pro's vid editor has genuine stats. This is because, it reports this while loaing. When I loaded "Linkin Park - Numb" vid, it showed the FPS to be 12. And yes, I can make out that the FPS is considerably low. With the other 2 vids, the FPS is 25 (in BMP's vid editor). And yes, the motion is smooth in these vids.

The report of 30FPS in TMGenc (as I said earlier), is with respect to the destination file, so no worries there.

The only FPS problem is with Winamp 5.07 which, if you are correct (and you certainly are), is unable to play the file at the intended FPS. Once its encoded in MPG format, yeah baby, full FPS!
