HDV workflow ?
hiya,
I captured 3 tapes of progressive HDV shot on a Sony Z7 in Premiere. I was expecting premiere to make M2t files but it didn’t, I now have a folder full of mpeg files.
These are generally clunky. When I open the folder in Vista, the Explorer crashes ??? In after effects they just make the application crash or they say that they don’t display properly and just show a “still proccessing” plate and the framerate is erroneously shown as 29.xxxx fps.
Its difficult to google any OFFICAL info on this but it would appear that when taking HDV into AE its best to change it to something that doesn’t use interframe compression. Is this true of AE CS4 as well ?
And if so, what exactly is the best codec to export the HDV in ? I have 3 hours of this stuff so have to watch disk space. Some people suggest ANIMATION quicktime at best quality ?
any help will be gratefully received

when you say progressive, are you talking about 24p, 30p or 60p…?
if you are talking about 24p, then you would not want to capture an entire tape as a single file, you would like to capture each shot as a single clip. this is so you can remove the pulldown to get progressive frames, otherwise your progressive footage will be interlaced and you’ll most likely run into problems later on, particularly in ae…
as for hdv… hdv doesn’t work well in ae. that doesn’t mean you can’t edit in hdv, but you’ll want to export clips to another codec to work with in ae. lossless animation is a great codec to work with in ae… you won’t lose any quality, it supports alpha channels and it works well in after effects. it does create very large files, and i doubt you want 3 hours worth of lossless footage eating up your drive.
as far as other lossy codecs that work well in ae, look for a codec that uses only intraframe compression (versus interframe compression). dvcprohd, apple’s pro res 422, quicktime photo-jpeg and avid’s dnxhd are codecs that do not use interframe compression and will work well in ae. i don’t know if premiere comes with dvcprohd, avid’s dnxhd may be the best to work with in both apps.. it is similar to apple’s pro res 422, multi-platform, supports alpha and is free from avid, so you might give that a try.
