What do do when project shot in 60 p destined for 24p has some 30p segments?

Well the event came out ok.. but the GH1 did weirdness on me and again SOMEHOW it switched from a 60 shutter to 30 somewhere in the middle of 2 of my about 15min long clips.


ARGHGHGHGHH!!!!!

I have NO clue how this happened. I set everything manual.... shutter 60... iso 800, aperture a few stops from wide open - I had to adjust the aperture for a few extra hot lit segments.. perhaps I slipped and adjusted the shutter although I was paying pretty close attention...white balanced manual to a kid with a white shirt on stage, but the white balance seemed to drift.. again.. and I KNOW I set it manually. This has happened to me a few times. Focus to afs.. shot 720 60p in order to conform to a 24p timeline in vegas... but now I am screwed because 30p does not look good conformed to 24p... so half of it looks great.. the other has weird stutter in the motion.

The client propably wont even notice because it's just a copy of his son's high school performance but these are some high $$$ clients and I notice.

So what are my options now - I guess do the entire thing on a 30p timeline and output to 30p? I need to provide a standard DVD, a blu-ray, and a youtube clip.




The WEIRD thing is, there was a little performance that happened after, it wasn't important but someone asked if I could just keep rolling, and so I put the GH1 in full intelligent auto everything mode and shot it, and it was ....flawless....
this totally pissed me off.. I hear everyone bitching about auto mode destroys everything - but it adjusted everything without big jumps or hunting and the white balance didn't go kooky.... what gives?!?!

You might have bumped the knob by accident...I would master the whole thing to 30p and see how it looks.
 
Yeah that's what I figured... is that what the ae locks do? stop you from doing that very error?

It looks ok mastered to 30p.. it fixes the 'jump motion' of the clips that were in 30p because of the shutter that didn't convert well to 24 p... but to me, it looks too 'videoy' in 30p, and the parts that were in correct 60 shutter look way better to me in 24p...

I am nitpicking as I doubt the client will notice.
 
Several times, I've accidentally adjusted the shutter speed when attempting to adjust aperture on the kit lens. Using the same wheel button for both is perhaps not the best design. I haven't noticed the WB drift, but I haven't really shot anything that long that I can remember. I'd be interested to know what caused that, and if it can be avoided.

If the client asks about the framerate (fat chance), just tell him or her that 30P is all the rage. 30P is the new 24P!
 
So you are saying render the whole project out to 30p rather than rending it out to 24p and having some of the clips have some weird stutter, but the other clips looking right?

Yeah that is what I was thinking. I don't like the look of 30p myself but he prob won't notice.

30p will go fine to a DVD as well right?
 
Well.. I have done some tests, and rendering it to 30p did fix the motion, so I must have bumped the knob somehow and switched the shutter to 30 when I meant to adjust the aperture.

I did a small render test and it looks great on youtube, but my DVDs are coming out awful looking... not quite getting whats going wrong here. Using vegas 9 to edit the original 1280 720p files... setting project to 29.97 progressive and rendering to 29.97 progressive widescreen

then authoring in adobe encore... all goes well but when playing on a normal tube television it looks very blurry.... the youtube again looks beautiful.. I never thought I would reach the day when the youtube version looked better than the dvd version...

somewhere in the downscaling from 1280 x 720 to the 720 x 480 (or 853 x 480 widescreen) something is getting fuddled...

A couple things:
Sounds like you've decided on the framerate, but when I get in that situation, I ask myself
are the 2 parts at 85% of what they could be better than one part 100% and the other X%?

If the jittery motion is noticeable, then that X is probably small enough to be worth doing the whole thing at 85%.

As to the DVD version looking blurry, are you comparing it to a 720 or 1080 version on Youtube? Because, in my opinion, that version will be better. Despite the heavy compression, it's way more resolution, and it certainly isn't like DVDs are uncompressed.

You also said that on a normal TV it looks blurry. Do you mean a normal HDTV I assume? There's not some difference between a normal Tube TV and normal HDTV.

Finally, you're a professional, so I would assume that you know about bitrates and how to set Encore to the highest possible and fit on the disc (up to 8 mb/s), but figured I'd better at least mention it.

What kind of file are you exporting from Vegas for Encore to use?
 
In all actually I played the DVDs on some computers and DVDs and while, yeah, compared to the youtube HD they don't look good, they look fine for standard def and the customer was more than happy. I think my eyes have fully adjusted to HD on my 1920 x 1080p monitor and now anything less looks 'blurry' to me even though it might be stunning to another individual.

I don't encode with encore, I encoded with vegas to mpeg2 30p as high bitrate 2pass as i could widescreen enhanced.

when I said 'normal tv' I mean t an old 4:3 tube tv where the dvd player is then playing it in letterbox.
