I am using Macbook Air.Can anyone please suggest me a good Video Editing Software on Mac( probably free or minimal price) I need to edit my wedding videos , so quality is the most important criteria. I have heard about Imovie and quicktime. I found that with quicktime , I can only trim from beginning/end but my requirement is to cut the video at several points not just at beginning/end. So I tried IMovie but I am unable to open my videos in IMovie even though the extension is .mov . Then I tried converting my videos for IMovie compatible codec using "MPEG Streamclip" and "iDealShare VideoGo". Both tools converted my videos but now I can only hear the sound and no video. Then I tried "ISky Soft Video converter" and it has successfully converted my video and I am able to open it but it leaves a watermark. I need something which is free , doesn't leave watermark and can convert my videos without compromising on quality. Does converting in some other codec degrade quality? Please suggest some software.Thanks in advance!!
