Jan Kielland Posted September 17, 2006 Share Posted September 17, 2006 Hi Will the quality of the picture look better if it's shot HDV then exportet from the camera as DV, or will the result be the same as if it was shot DV? Jan Kielland Link to comment Share on other sites More sharing options...

Jan Kielland Hi, Motion is more compressed in HDV and a dropout very nasty. You need to test what you are shooting, but I would probably record HDV.

Aleksandar Bracinac Posted September 17, 2006 Share Posted September 17, 2006 Shoot as HDV, import as HDV and after that re-render everything in PAL/NTSC uncompressed for color correction if needed. I've shoot recentily some documentary with Sony FX1 and I'm very impressed what I've made with Vegas & Magic Bullet Looks from this material. Much better than you can do with DV.

Matt Sandstrom Posted September 18, 2006 Share Posted September 18, 2006 if you know you'll never need the hdv you should probably shoot in dv. the quality will normally be exactly the same, but you reduce the risk of nasty dropouts as well as some of the aliasing and banding you get when you pan fast in hdv. but i agree the extra res is good for post processing, so editing and grading in hdv and downconverting as a last step is probably the best advice. /matt Link to comment Share on other sites More sharing options...
Aleksandar Bracinac Posted September 18, 2006 Share Posted September 18, 2006 For HDV, if you targeting SD as a final format, the downconvert to SD should be before grading, as image rescale algorhytim "smooths" mpeg artifacts and after that the final SD is much easier to grade than original HDV.

Matt Sandstrom Posted September 19, 2006 Share Posted September 19, 2006 true probably even better done as one step. use the original hdv files in an sd composition/sequence/whatever. same thing but with no extra disk space and no recompression, plus it allows for high precision 4:4:4 rendering of everything. /matt Link to comment Share on other sites More sharing options...
Mr. Shannon W. Rawls Posted September 19, 2006 Share Posted September 19, 2006 Hi Will the quality of the picture look better if it's shot HDV then exportet from the camera as DV, or will the result be the same as if it was shot DV? Jan Kielland Jan to answer your question exactly as you've asked it. The answer is NO in my humble opinion. I beleive if you were to aquire footage in HDV and have the camera itself downconvert that HDV to DV via firewire, then the footge will look identical to if you aquire it in DV and captured via firewire. The question I have for you is, why "wouldn't" you aquire your footage in HDV? Now remember, I say this only because I've tested it using this method and that's the result I got. HOWEVER, when I downconverted HDV to MPEG2 to make a DVD or I downconverted HDV to DV using a NLE...the result was NOTICABLY better. This is why I suggest people who own HD cameras, always shoot HD.

Matt Sandstrom Posted September 20, 2006 Share Posted September 20, 2006 I beleive if you were to aquire footage in HDV and have the camera itself downconvert that HDV to DV via firewire, then the footge will look identical to if you aquire it in DV and captured via firewire. that depends on how you define identical. it may very well look exactly the same, but it will have gone through another generation of compression, so it can't possibly be "techically" identical. it's also very possible that scaling raw ccd data is more efficient that scaling an hdv frame. i don't know but it's not unlikely. it's certainly possible that you would get slightly better quality from shooting in dv. i'd still shoot hdv for future proofing but if this is for a client who wants sd and that you're not likely to hear from again, i can't really see the point. "possibly" better quality, less risk for dropouts, the ability to use the tape in a dv deck, are definitely the pros. the cons are few. /matt Link to comment Share on other sites More sharing options...
Mr. Shannon W. Rawls Posted September 20, 2006 Share Posted September 20, 2006 (edited) Matt, who said anything about being 'technically' identical. I beleive I did define it. Please read the word I wrote right before I wrote the word "identical". *smile* Edited September 20, 2006 by Mr. Shannon W. Rawls Link to comment Share on other sites More sharing options...
Matt Sandstrom Posted September 20, 2006 Share Posted September 20, 2006 (edited) Matt, who said anything about being 'technically' identical. duh, me? :-) I beleive I did define it. yes, and i pointed out that if you define it differently the picture changes. no pun intended. /matt Edited September 20, 2006 by Matt Sandstrom Link to comment Share on other sites More sharing options...
