Question :How to convert 1080i HD for Vimeo and Youtube playback?
"I'm working on a How-to video. I'm a biologist, and I'm way out of my league on this project. I've made one video before using iMovie 09. Everything was going great until it came time to convert(?) encode(?) it so that it could be streamed from Vimeo, I recorded the footage in 1080i HD 16:9, and apparently iMovie 09 had some issues with interlaced video. Now I'm ready to convert so that it can be watched on Youtube and Vimeo. The video is 15 minutes long.Any advice or guidance would be greatly appreciated.Thanks!"
Well, interlaced video must be correctly deinterlaced for web video delivery including Vimeo, YouTube, etc. If you're outputting 1080i, deinterlace and resize to 1280×720 before you upload. If your final outcome is a progressive medium (web, HDTVs, Blu-Ray, etc.) you might want to deinterlace before you even start editing. Below is the tutorial on how to deinterlace 1080i video for YouTube, Vimeo.
First of all, we recommend you Brorsoft Video Converter for Mac, which is the best de-interlacer for you to get rid of the interlacing effect.
