I just got a new Sony DSC-T99 Cypbershot camera. the "HD" video files that I've been taking will not play in quicktime. I import them through iPhoto, then when I double click the video I get the following message. "Additional software is required for QuickTime to playback this media. It may be available from the QuickTime Components page." Then it will play the audio but the screen is black.

the files are .mp4. I think 1280 x 720.

I tried importing through iMovie '09 and was also unsuccessful.

Any suggestions... I dont want to have to convert files everytime I want to watch a video I recorded.

thanks,
jake

    The MP4 file extension refers to the file container. This particular container may be used with MPEG4/AAC or H.264/AAC content which come in many "flavor/profile" variations which may adhere to the standard, contain hibridizations, and/or be of a proprietory nature. Further. Thus, normally the first step to finding a solution would be to learn exactly what data compression is being used and with what profile and at what level. If you can't determine this on your own, you may want to post a sample snippet online so one of the regular responders here can further analyze the content.

    Based on your description, it would appear the video content is in a non-standard compression format. QT is very touchy about standards and that is likely why it will not play it. The question, however, is whether or not there is a QT component is available that you can download/install to play the video without having to convert it to a QT compatible standard. And, in order to check this possibility, you first need to know more about the video content and how it was compressed.

    If I wanted to post a sample of the video, how would I do that?

    If the file is smaller than your ISP/Mail client limit, email it. If larger and your ISP includes adequate free storage space post it there. If you have a MobileMe account, post it to your Public folder. If you don't have commercial online storage space available, check into site offering free temporary storage for the purpose of posting/distributing files. (Unfortunately, I don't use the latter, and so cannot suggest any by name for you.)_ If all else fails, email me and I will see about setting up a temporary password for you to post it my account area.

    I am told thh file is MPEG-4, AVC/H.264, Approx. 30 fps, Progressive, AAC, mp4 format. they couldn't tell me the exact data compression. I was however, able to watch the file using the VLC media player. Does that help?

    Not really. Information available online already indicated the 1920x1080 mode employed AVCHD (format developed jointly by Sony and Panasonic which was designed for Blu-ray disc compatibility) and the 1280x720 mode using MPEG-4. Since you were not 100% sure about the mode and did not indicate if your attempt to import via iMovie was done directly from the camera (calls special different import modules) or from iPhoto via the Finder (a simple Move/Copy operation) we still do not have the total picture. I would however, lean more towards it being an MPEG4/AAC file in an MP4 file container requiring an add-on video component. Nor have you indicated whether or not you have the Perian component package installed which might be able to handle the video data.
