Question

FLV video plays WAY too fast

I encoded an AVI w/ Media Encoder and dropped the FLV into a Flash playback component.

In my compiled SWF, the video plays in hyperspeed (like it has a really fast framerate), but the audio plays normally.

It seems like an encoding issue, but could it be something in Flash?

I'm guessing there's some setting mismatch -- different bitrate, framerate, dimensions?

I've recorded a couple screen capture vids (.AVI files) w/ CamStudio.

CamStudio's video options:

Compressor: Microsoft Video 1

Quality: 70

Set Key Frames Every: 200 frames

Framerates

Capture frames every: 5 ms

Playback rate: 200 frames/sec

AVI file's properties under Windows:

Size: 168 mb

Width: 1098 px

Height: 823 px

Bit Rate: 56kbps

Frame rate: 200 frames/sec

Data rate: 2290kbps

Video sample size: 16 bit

Video compression: MS-CRAM

I encoded this file to FLV with Adobe Media Encoder several times.

I tried a couple different presets, but I don't understand what the cause might be.

    The setting that seems odd to me is the 200fps frame rate. Is it in fact 200fps, or is it actually 20fps?

    It IS, in fact, 200fps.

    I opened it in After Effects to verify.

    Yikes.

    WTF

    Well, I'm trashing this CamStudio (cr)app.

    But, now how can I get my 200fps video to play at a normal speed when encoding to FLV?

    Thanks for your help.

    I suppose you could just set the framerate to something reasonable  in the encoder (30fps might be a good start). I've never tried encoding from a source with a rediculous framerate like that, but I suspect that would do the trick.

    On the CamStudio issue, does it not have settings for capture framerate? I would think the best solution would be to set it to the framerate you want for your FLV.
