To get the best performance possible for video playback, it's best to use dimensions that can be divided by 16 ... like 512px x 288px for the video content.
Finally add player bar vertical dimension if necessary (like 25px for Youtube).
Reason:
Video Encoding is done in blocks of 8 or 16px, depending on the codec used. Decoding is much faster when the target display size fits into this 8 or 16px raster, so the decoder doesn't have to unnecessarily re-scale the video image.
Fix:
Change Vimeo video dimensions to 512 x 288 (playback controls are superimposed)
Change Youtube video dimensions to 512 x 313 (512 x 288 plus 25px player bar)
