Q: HDV file - need to burn to Blu-ray, help please

I have a 75 minute 1080 HDV50i video file which I need to burn it to Blu-ray for a screening in the US. Can anybody suggest the best way of doing this? Do I need to convert it before burning? And what is the best way to burn to Blu-ray? I have an LG Blu-ray burner.

    if you've got fcp7 you can "share" to bluray.  You can also use compressor.  Either way will compress the file before authoring the bluray.

    But will 50i be playable on a US Blu-ray player? I'm told not, and I should convert it first but I'm not sure how or what to.

    There are probably simpler ways of doing this but this should work.  When your edit is done, duplicate your sequence, open the sequence settings for the duplicate and change the codec (or compressor) to prores 422.

     

    Export this sequence with current settings.  Open the resulting file in cinema tools and "conform" to 23.98 fps.  (or the closest frame rate to that - some applications just give you a choice of a frame rate close to that).  Bring this file into compressor or fcp and you should be able to make a blu-ray that is compatible with US players.  All blurays in the US (and all US dvd players) can play 23.98 material as most feature films are shot at 24 frames per second and the transfer to video/digital usually involves slowing the film down slightly (just as most feature films in Europe are sped up slightly to 25 fps)

     

    If there's a more straightforward method available, hopefully someone else will speak up.  I've never done this but it should work.    As always, I'd recommend making sure your end user tests the disk before the big showing.

    Just to add that CT will change the original source clips, So you may want to make copies of them before conforming.

     

    While Compressor can do this as well, it's not nearly as fast or straightforward a process as using CT.

    Thanks guys - how do I encode the file for Blu-ray burning? Do I just add the file to Toast or do I need to create streams of the audio and video as per DVD?

    I suggested he export a selfcontained qt of a duplicate prores sequence, and then send the resulting qt to cinematools.  No original clips will be effected with this workflow.   Of course, duplicating files before doing anything that will change them is never a bad idea., but in this case not necessary.

    Haven't done a bluray in compressor, but if you bring the "conformed" file back into fcp and choose "share" from the file menu, fcp will walk you thru the process.
