First off, I am a proud owner of an HV20 since last weekend. I love it. I am just now learing about what it can do. I just figured out and watched the Exposure lock, Gain control video that is posted here.. I think the lack of grain in low light is one of the most important aspects of professional video... I am so glad I know how to do it now because of this forum... Thanks guys.. I have been lurking for a couple weeks...


Well anyway...
Ok, I need to deliver some clips to a person/company.
I was thinking about just giving then an m2t file? Is that proper? It would not have the Reverse Telecine done to it yet (I shot in 24p)
A couple things:

1. Would it be rude not to IVTC the Clips before delivery?
2. What is the best format for delivery (on a professional level)
3. Finally.. what would an acceptable quality be. Like how many megs per second (file size) if I were to deliver Quicktime MOV Photo-Jpeg files. Do I have to set the Quality for Photo Jpeg to "BEST"? I hear that the MOV Photo-Jpeg file is a great standard for delivery.. all editors can work with it without haveing to do more convesions or crunching.

For instance one 5 second clip I have is 39mb/m2t it ends up being 81mb after I IVTC the clip and export it to MOV/Photo-Jpeg.

Does that seem right? or too big? Would medium Quality be ok For the Poto-Jpeg setting?

Any input would be most appreciated ..


Also.. what about m2v files... I demuxed an m2t to an m2v .. the m2v opens up in more software.. I wish I could figure out a program to IVTC an m2v file!

The best delivery format is the one they ask for... and if they don't know what they want or need, it probably doesn't really matter much anyway.

hmmm... Understood.. Thing is.. I don't believe they even know what they need. They will be using the clips at a future date, and will not be doing editing themselves. They have not chosen a "post" company yet..

So I really don't know. That's why I was asking. I figured that the pros here on this site would have something useful for me to chew on. I really don't need the obvious stated... because it's so, well…. obvious.

I really just need to know a few things. It is my first forum post. So I understand what "spin" that puts on things. I am a member of many forums... I hope this forum is as helpful as the other forums I am a member of. Not being a pro, I will not have much to contribute myself, but of course would always share what I know. I was just hoping for more from what seems to be a very intelligent community here at HV20 dot com.

If anyone has anything that might be a bit more useful I would be most thankful.

Sorry if my last post was a little flippant. I can see how it perhaps wasn't very helpful.

I guess what I could have said is there is no "best" delivery format. What's good is really relative to what they want to achieve. Without any other information, I'd say best is to give them the original tapes or .m2t files since there is no conversation loss. But even better would be to capture .avi files via HDMI and give them those on a hard disk. As for removing pulldown, they or may not need that done depending on how they plan to output the files.

It's not about you being rude or inconsiderate. They should have some idea of what they want or need. Or else you can't really know what's best for them. If you're really stuck, offer them the .m2t files and offer to remove pulldown later if necessary. (The problem with doing pulldown removal now is you'll end up with intermediate 24p files that are larger than the .m2t files.) Personally I can't speak to the Quicktime .mov/jpeg files. Don't think they'll be much good to your clients though if they don't edit on Apple.
