30p for the Internet ... WOW!!!

okay, okay... so I finally discovered 30p. ;-)

on 6-4-2008 (last night) I did a short test of shooting in 30 frames per second progressive for video to show on the Internet as opposed to shooting 60i (which gives 29.97 frames per second interlaced used on television, which I normally shoot for) ... it was a MAJOR difference in quality of the resulting streamed video.

see the test at:

http://1vid.com/the-news/1-latest-ne...ideo-test.html

there is a link there to see it in full HD if your Internet connection is robust enough.

I was very pleased.

And check out http://exposureroom.com, which I use for streaming the video. They do a pretty good job with HD (1280/720).

this video was edited in Adobe Premiere CS3 and exported via Adobe Media Encoded to a 1280 x 720 MP4 file and uploaded to http://exposureroom.com.

Ralph, the 30p is looking quite nice for computer display. HD is showing well.

Couple comments:
The high-contrast fine detail of the black wire shelves behind you show more compression artifacts than anything else you included. The fine detail of the leaves & grass is probably artifacted as well, but it can't be seen because of the organic shapes.

The shot of syrups on the shelf really reminds me just how good the V1 can look in HD. I usually shoot in HDV, but to date all my distribution is SD.

Of course the motion & general look of the exterior scene is very good as well. It would probably benefit from a little color correction to intensify the colors.

It would be interesting to see a slowmo of the cars passing by. They appear to strobe a little, but that could well be MP4 compression stuff. 30p should make pretty good source for slowmo.

Thanks for sharing that test. I often advise people to shoot 30p for computer/internet distribution - your HD really shows why.

I shoot with a V1 also for the last 1 1/2 years and I shoot just alittle different ending up with 30p, I shoot 1080i and capture my interlaced clips with cineform either set to high or filmscan, and let cineform deinterlace only, move it into Vegas on a 29.97p timeline and render out as mpeg4, here is a clip let me know what you think, http://www.hughmobley.com/arboretum.html
now, here is a clip I shot at 30p edited it at 30p in vegas, and you can see the difference, especially when the camera is panning, alot of motion blur, etc. I am not happy with this at all. http://www.hughmobley.com/queen.html, this one was done as wmv but it still shows the blur when I render it mpeg4, I have all but given up shooting 24 or 30 p unless the situation is very controlled, and then I might not. changing it to progressive on the timeline has worked better for me. When I make a dvd I am getting exceptional dvds doing it this way. I play my dvd.s on a hd 720p tv and they are very good this way, but couldn't with 24 or 30 p stuff from the camera.

Thanks Hugh... I watched that video and, of course, have seen others of yours. Very impressive!

I will definitely try it your way also.

Yes, 30p is a good way to go for internet. What do you all think of 24p as another internet alternative for creating even smaller file sizes?

Thanks, nothing aggrevates me more than to have a very fine and capable camera like the V1 and have struff turn out like crap, I spent a week filming in Colorado last year, did it all 24p, big mistake, actuallly we are planning a pilot for TV and we will shoot it with a Z1 and my V1. The camera really puts out an image when going straight to my HD tv thru hdmi.
