having completed an Hour long Project in HDV I want to archive back to tape.
When I first pressed export to tape I got the usual Export to tape dialog box but when I pressed record button although the sequence played the tape deck ( another camera) didnt Record.
when I tried again I got a Box export to HDV which I guess is actualy correct just with a render and record button and a done button.
Hitting the render and record brings up a trancoding to HDV progress bar which doesnt seem to move very fast so i guess this might be a long process.
Any idea how long for an hour project ( I know it depends on processor speed but typically how long)
I want to know should I go to bed and just leave it.
Hi
I don't know about the specifics of PPro, but on average it seems it can take up to several hours to conform an hours worth of HDV - because its going through and rebuilding every keyframe and GOP to take account of the new edits, transitions and filters.
Well its surprised me!
Ive come back and taken a look at it and its already started to write to tape and done 13 minutes at 22:34 so it must have taken less than an hour to convert to hdv before starting to write out to tape
I am impressed.
You can't just export back to HDV, you have to create the MPEG2 elementary stream first. That can take anything from real time to about 3 times, depending on your machine. Once that streams been created, you can then export it to tape, and the camcorder will show it on the viewfinder while it happens.
Doing the process on the fly as you have done is fine if the machine is up to the job!
And it can render as it puts out to tape - There is a lag before it starts outputting but if the output caches up with the render head during a complex section of the timeline :(
So If you have a fairly fast machine then fine - If Not then create the m2t first as suggested and then output to tape.
Don't know how PPro works, but for comparisson, Avid Liquid goes through the full render to m2t first, everytime you write to tape. The render process takes about 10-20% longer than real time. This is OK if you are making one copy but if you are making several copies, as I had to recently, it is a right pain. Next time, I will use two cameras and dub the second copy from the first!
So If you have a fairly fast machine then fine - If Not then create the m2t first as suggested and then output to tape.
Well the machine is a Dual Quadcore processor machine built by DVC so I didnt expect to have any problems and it seems to have worked just like Alan said it woulld I.e I could see the output being recorded on the camcorders LCD screen.
One advantage to creating the MPEG file before putting it to tape is that you can use a compressor that takes longer because it takes more care. I realise that this is a post-rationalisation, but it does have an advantage.
If I recall correctly Premiere does make a file first then writes it to tape. However in my experience back when I was using PPro 2 I found this very unfriendly since the file it makes is temporary and deleted at a certain point after the tape is written making it unavailable for future use.
I remember having to leave the cam powered up for hours while Premiere kept me waiting wondering what was going on as it did it's "behind the scenes" stuff. No information on what it was up to and of course I would wonder it it was working properly or just wasting my time, then when the temporary file was made the cam started recording.
Not being one to put up with doing this over again just to write to another tape I eventually tracked down where the temp file was being stored and was able to copy it to another location before closing the record process, it gave me a warm feeling I has got one up on Adobe this time!
That's one of the things I like about Edius 4, it makes the MPEG file, showing where it's got to on the time line, while estimating the time to conclusion. It keeps the file like any other, and then you use a "write MPEG transport stream" plugin to write it to the camcorder. Lovely. The file stays until I delete it.
Yes Alan I see you are a convert! IMHO an excellent software only editor! or an even better hardware and software package!
Have you looked at the PRODAD software set yet? well worth a look as a plugin for EDIUS
Ooops slight Hijack.............
Back on topic
Well the machine is a Dual Quadcore processor machine
Eeerr Yes that will do it !!!:) Pity you are not using GV EDIUS on that machine would be an eye opener:eek:
