I have a mac and am having trouble with Crunch's "Save to iTunes" facility.    

I am creating some .mp4 files which play perfectly on VLC, but when I try to import them into iTunes, the sound is fine but the picture only changes frame every five second or so.  I've tried dropping the resolution to 320 by 240 but to no avail.  

I'm not sure where the problem lies as I successfully used Crunch to import a downloaded film into iTunes, so I'm wondering whether it is the .mp4 format which is at fault?

Any help would be appreciated.

I'm just about the only person who looks in this forum and I don't know what would cause the issue with your videos in iTunes. What settings did you use in Crunch and what format was the source video?

You might check the iTunes forum at discussions.apple.mac to see if there have been other threads about video playback problems.
I'm just a fellow Toast-user so please don't blame Roxio for any misguidance I may provide. And do let me know if your issue gets solved. Cheers from Eugene, Oregon!

iTunes can handle just about any file format that works with QuickTime and will play any file purchased or downloaded from the iTunes Store. If you've got video files that end with a .mov, .m4v, or .mp4 file extension, you can import them to iTunes with ease. However, the video especially the MP4 video must meet the following specifications: it must be encoded as 540 kbit/s (minimum) MPEG-4 video (H.264) with an approximately 128 kbit/s AAC audio track or encoded as 1.5 Mbit/s (minimum) MPEG-4 video (H.264) with a minimum 128 kbit/s AAC audio track. If not, you will fail to import MP4 to iTunes.

Even if your MP4 files meet the above specifications and are added to iTunes successfully, it may still fail to sync to iOS devices. For iPhones, iPads, and video-capable iPods play videos in more specific video formats and codecs.

In order to successfully add MP4 to iTunes as well as sync MP4 to iPod, iPhone, iPad, we have better convert the MP4 files to both iTunes and iOS supported MPEG-4 format.

The following will introduce a step by step guide on how to convert MP4 to iTunes and iOS devices including iPod/iPhone/iPad/Apple TV compatible video format  at MP4 to iTunes - How to Add MP4 to iTunes for Transfer MP4 to iPod

MP4 is a media container format which can be encoded with many different video and audio codecs like DivX, Xvid, H.264, H.263, MPEG-4, AC3, WMA, AAC, etc. While iTunes only support few video and audio codec like MPEG-4 video codec and AAC audio codec; H.264 video codec and AAC audio codec. If the MP4 video is encode with iTunes unsupported video or audio codec, iTunes will not add and play it.

Sometimes, even if the MP4 is in the right video and audio codec that iTunes supports and we can successfully add and play MP4 in iTunes, but if the MP4 video does meet the technical specifications for iOS devices like video size, bitrates, sample rate and etc, we will fail to sync and transfer the MP4 video from iTunes to iPod, iPad, iPhone, Apple TV and etc.

To solve can't add MP4 to iTunes for playing MP4 in iTunes or transferring MP4 to iPod, iPhone, iPad, Apple TV, a recommended solution is to convert iTunes unsupported MP4 to a more compatible MP4 video format.
