converting xpress pro hd sequence to m2v or m4v
By the end of today I need to upload a 2 minute sequence that’s in my xpress pro hd, first converting it to an m2v or m4v file. So far the only exporting I’ve done is creating an mov file and burning that to a disk with idvd. I’ve tried to follow advice gleaned online, and I even sprang for Sorenson Squeeze. I’ve seen instructions to first export the sequence as a Quicktime reference file. When I try to do that I get a message: “Long GOP media cannot be exported using Quicktime Reference. You need to export the sequence using Quicktime Movie.” Is there some setting I’m doing wrong? Is there a way to export as a mov file and then convert to an m2v or m4v using Sorenson Squeeze? I’ve even seen the suggestion that I can change the .mov to .m4v and that this alone will work. A final novice question: how can I best determine before the last minute that when I uploaded it via Yousendit.com that the recipient will actually end up with an m2v or m4v file? Any advice will be greatly appreciated.

Sounds like you’re cutting HDV footage. This can’t be exported as a quicktime reference unless you transcoded it to DNxHD first. So just export a quicktime movie like you have been doing. It’s a good way to go.

Yes. Export it as a quicktime movie, open Sorenson, drag the quicktime into the program and either select a preset for m2v or m4v (if there is one) or make a new present and customize it.

Once Sorenson has compressed your quicktime to an m2v or m4v, that’s what file it will be. If you upload that file to YouSendIt, that’s what they’ll get.

Thanks very much for your advice. I seem to have succeeded in converting it. I end up with separate video and audio files, an m2v and an m2a. The place I’m uploading to has specified saving in m2v and aiff. The audio file – the m2a – is labeled as a quicktime document when I get info on it, whereas the video file is labeled as an mpeg-2 file. Do you think there’s any reason the folks who are receiving this would not be able to use the audio file in this format? I emailed them asking this, and whether it would be safer to send them an m4v file (which is their second choice), and got back the not too helpful answer: “Do the best you can” from someone who is probably very harried on a deadline day. I’m experimentally trying to convert it to an m4v but it’s taking forever. Still, if that works that might be the way to go.
