I imported an mp4 to iMovie. Ive been using it for years but

Resolved Question:

I imported an mp4 to iMovie. I've been using it for years but never encountered this specific problem.

Whenever I try to edit the speed of certain clips, it says I have to "Optimize Video" but when I do that, playing back the video, even after export, only shows the first frame of the project for the entire project. I have no idea what's happening, and now my work to this point may be lost if I can't "un-optimize." the footage.

Also in its un-optimized format, every clip stutters for a moment before actually playing.

Thank you in advance for your help, as this is a very important project that I need to be done ASAP.

Cheers,
David.

Hi, Thanks a lot for posting your query here. I am Jins here to assist you. Actually imovie is designed to work with .mov files. It can't identify mp4 files. So, while importing mp4 files it will re-encode the file and that's why you are facing this issue. So, please use a converter program to convert your mpl files to mov format. Then import that mov file to imovie.

I like to recommend you a free video converter named MPEG Stream Clip. Click here to download it.

 

Install and launch MPEG Stream Clip. Drop your file onto the middle of the MPEG Streamclip window and then select the File menu and then Export to Quicktime. Set the compression type to Apple Intermediate Codec, leave the quality at 50% and sound at uncompressed, stereo, auto. Select the frame size if needed. If the source was interlaced, check the box next to Interlaced Scaling. If the source was originally 720p then you can uncheck this box. That should be it. Click Make Movie and then import the file it makes to iMovie.



Regards
Jins

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
