i would love to keep my resolution as high as possible before downconverting to 720p for final output, will 1080/60i reduce the quality when finally exported to 720p as a master? [obviously for slo-mo ;)]
which is better and will keep quality sharp and great? 720p/60 or 1080i/60?
i heard 1080 is the best in hmc150 when you downconvert to 720p when you export your master for just regular 24p frame rates, but for slomo/60 fps, im not sure :/ help?
thanks!! (:

im get all OCD when it comes to workflow and preserving the quality of the footage... ): or maybe that can be a good thing (: heeellp! xP

[also, should i get 7D or HMC150 for better use of camera? as in liike, what are the pros and cons? i like the shutter speed selection in hmc150 but idk about 7D, but im sure im going to stick with hmc, i just want to know what are the differences, im ocd like that.]

60i would be very similar to 30p... I would go 720/60p

There is no way you will get me to trade in a HMC for a vSLR - but thats my needs. The differences are widely posted.
 
720/60p

If your final output is going to be 720/60p then you should shoot in 720/60p. The only down side I ever see in shooting in 720/60p is downconverting to SD DVD takes longer. If you plan on using Slo Mo at all then I would plan on shooting 720/60p.

If you do some searching around on the forum you will find quite a bit of info about why others shoot in and why they like it. I think with this camera the majority shoot in 720/60p especially if they are shooting events.

Just my Opinion

Well I just went back and read the following thread
http://www.dvxuser.com/V6/showthread.php?t=164832&highlight=720/60
and it seams that Barry now thinks that 1080p is the sweet spot for the HMC150. Personally I will probably still stick with 720/60p. For one because it is easier to edit with. Two, I like the slow mo capability of it.

I have and will continue to shoot 1080 for cooporate stuff or green screen work.

Forgot to mention in my previous post that I would not try to shoot a bunch of video with a still camera. Yeah you can get some good looking footage, but it is not a video camera. What are you going to do about audio? Sure if you want to use it for some shots here and there fine. Or if you are putting something together where you do not need natual audio or a feed from a mic or board then it would be OK, but I would still prefer to shoot video with a video camera.

I prefer 1080p for the film look stuff, and 720/60p for the reality-look stuff. I wouldn't use 1080/60i unless a client specifically demanded a deliverable of 1080/60i; I prefer 720/60p over 1080/60i.
 
i mean i would go 1080p all out if i didnt need slow mo, but for slomo would it be better for 720p/60 or 1080i/60?
 
okay coolio, so since i would like to film with 1080/24p for my shooting purposes and if i need slow mo ill just use 720/60p and put it in my final edit and export the whole master as 720p, sounds fair?
 
okay,
but if it was for 1080 master, wouldnt uprezzing the 720 footage to 1080 decrease sharpness and quality?
 
Of course -- but not as much as de-interlacing 1080/60i into individual frames. That costs you half your resolution. Up-rezzed 720p will be about 80-85% as sharp as the native 1080p was.
 
okay! thanks! i just realized that hehe thanks for ringing the bell! so to get this straight:
1080i is pretty much HALF that rez because of the interlacing.
720p uprezzed to 1080 would be [like you said] 80-85% of it, because 1280x720 compared to 1920x1080 is more than 50%[half] of 1920x1080 which is 960x540.
i think i get it! (:

just wondering, do you know where to buy the cheapest NEW [untouched] HMC150 online?

Thanks again.... you probably saved many people from 'wasting' their money on film college [although i think film college would help also] xP
thanks!!
 
I don't know who has specifically the cheapest deal, but we always recommend supporting the folks who support us. Site sponsors like Spec-Comm, Abel Cine, E.C. Professional Video, EVS, VideoScope, etc.
They help us pay our bills around here, so it's always good when the members can buy from them.
 
I recently did some testing in Edius and found that 1080p content put on a 720p timeline was not as sharp as true 720p footage on that same timeline.

I would be interested in others experience with this. Edius seems to be very good a different formats mixed on a timeline. One would think the 1080p content would bring a lot of detail.

So I am of the mindset that unless you are delivering in a 1080p format, like 1080p24 Blu-ray, 720p seems like the best overall resolution.

720p60 goes to Blu-ray and it goes to DVD as well. I also have had good success with shooting 720p60, outputting a Canopus HQ file, putting that file on a 720p24 or 720p30 timeline, exporting that back out to be put back on the 720p60 timeline. Sort of a 24p or 30p look inside of a 60p project.

Kind of a best of both worlds with the safety of shooting in 720p60.
 
Well what I found was 1080p material on a 720p timeline was not as sharp as 720p material on a 720p timeline.

1080p in its own native format has more detail no doubt.

So shooting in 1080p knowing you were going to edit or deliver in 720p would not give you more detail as some is lost in the downconvert.

This is just some test footage I shot to compare. I would like to hear some other experiences.
