Solution pour exporter un montage HD de Final Cut Pro pour en faire un joli fichier .mov pas trop lourd.

Trouvé sur le site de Vimeo (par ailleurs excellent !).
Donc au moment de EXPORTER, vous cliquez sur les options de réglages et suivez les instructions suivantes.

• Codec

  Choose H.264 for the video codec. Choose AAC for the audio codec.

• Frame rate

  This is usually 30, in Europe it's usually 25. If there is an option that says "current" just go with that. Please note that Vimeo converts all HD videos up to 24 frames per second for optimum playback performance.

• Keyframes

  Every 30 frames. This is basically how often the compressor references your uncompressed video.

• Data rate

  1800 kbits/sec (for regular video) or 5000 kbits/sec (for high definition). Making this number higher will increase both quality and size.

• Size

  640x480 (for regular video) or 1280x720 (for high definition). Please note, 1440x1080 videos will not be widescreen on Vimeo, you must compress them as 1280x720.

• Deinterlace

  Yes. If you do not deinterlace, you will often get weird-looking horizontal lines in your video.

• Sound sample rate

  44.100 kHz

• Audio quality

  You want audio with a bit rate of 128 kbps. You can set your audio to really good quality without increasing file size too much.
