Problems with Vimeo Encoding |

| Hi
I want to upload a video segment to play in the best possible quality on Vimeo. My footage is captured on Canon XM2/GL2 in SD, edited in Avid Liquid, exported as an .AVI, and imported into SUPER. Then, I have followed instructions found here:- http://eugenia.gnomefiles.org/2008/01/11/from-minidv-to-vimeo-in-high-quality/ However, when I view the resulting .MP4 on Vimeo, the results are less than impressive. Picture quality has been reproduced OK as in resolution, but my issue is with 'stuttering' - i.e. the picture is jerking too much, particularly noticable in camera movements such as pans. I have seen excellent quality videos on Vimeo, shot in SD and on the same camera without this jerkiness. Could it be a bitrate issue, or is something else wrong? Eugenia's recommended settings for SUPER:- http://eugenia.gnomefiles.org/images/super-dv.png Note that my footage is PAL, so I have changed the SUPER setting of 29.97 fps to 25 - everything else is exactly the same. If Eugenia's guide to achieving high quality Vimeo is not quite right, could someone help me smooth things out, i.e. what to tweak or change, or use a vastly different method? Many thanks. |

| It sounds like a framerate issue, maybe vimeo changes the framerate. Google for vimeo framerate or similar.
Does the mp4 play fine on your computer? And I would convert to mp4 with h264 and aac audio using handbrake or xvid4psp instead of super. You can use same settings as in super, 1280x720, 25fps, 5000kbits or use constant quality encoding mode. |

I tried the exact same Super settings, but with 29.97 fps selected - results are with similar jerkiness on Vimeo. Again the .MP4 plays fine on my computer. According to Vimeo staff, "SD is 30 fps".... ? http://www.vimeo.com/forums/topic:12455 I suspect I would not be having these frame rate issues if I was on NTSC - I think it is a 25 fps/PAL problem. But what to do if 25 fps/PAL is my capture, edit and export format? I guess I'll try these other encoders you mentioned, but I'm wondering if Vimeo might not be handling 25 fps/PAL footage very well? Anyone got a recipe for successful, jerk-free PAL uploading to Vimeo? |
