Compression, Dropped frames Vimeo.
on Mar 6, 2011 at 12:13:33 am

I am having a lot of trouble compressing my snowboard movie. It looks fine in VLC, but once it gets to Vimeo the frames drop. I have uploaded 4 different versions today, all with dropped frames, I will now list my specs, as well as a link to the video with dropped frames.


Password: snow

Shot on Canon 7D at 60fps. Some shot's edited in AE using Timewarp and then brought back into Final Cut. Can't remember if I edited the shots as Prores422 or .Mov. I think it might be a mix of both.

Exported as Quicktime Movie

Compressed with either MPEG Streamclip or Final Cut Compressor.

Here are the formats I have tried, all get dropped frames once in Vimeo.

Compressor: File Extension: mov
Estimated size: unknown
Audio Encoder
AAC, Stereo (L R), 44.100 kHz
Video Encoder
Format: QT
Width: 1280
Height: 720
Pixel aspect ratio: Square

Frame rate: (100% of source)
Frame Controls On:

Deinterlace Filter: Fast (Line Averaging)
Adaptive Details: On
Antialias: 0

Field Output: Same as Source
Codec Type: H.264
Multi-pass: On, frame reorder: On
Pixel depth: 24
Spatial quality: 79
Min. Spatial quality: 50
Key frame interval: 30
Temporal quality: 50
Min. temporal quality: 50
Hinted for QuickTime
streaming server

And when using MPEG Streamclip: Export to Quicktime, quality 100%, Audio 44.1, 1080x720 Unscalled, deinterlaced, and fast start.

Please Help.

Two thoughts:

One, you can't judge if Vimeo's playback is dropping frames; that's actually a problem on your individual system. Something's not working there (such as flash) without dropping a frame. If you were to rip back the video from Vimeo and find the frames missing, then yes, Vimeo is dropping frames. Try a tool such as DamnVid for that.

Second, Vimeo publishes exactly what your upload settings should be here:

Hope that helps. I've had good success with the Youtube preset in Compressor 3.5 for Vimeo videos.

Best,
