So I'm working on this project with a bunch of old pictures and making a movie with them. I want to do it in HD so it will be future-proofed, but I have no idea which codec to use. I've tried the Apple Intermediate HDV Codec, HDV, DVCPRO HD, and I'm not sure which to use. I want to use a format that's 720p30. When I tried DVCPRO HD, it distorted the image and stretched it out badly, but that might have been some playback setting I had screwed up. HDV doesn't stretch it out, but I've read some things that say DVCPRO HD is better quality and easier to edit with. But I can't figure out why it's stretching out these images. This is my first time working with HD, so I'm pretty confused.
