Like huge waves ? GH13 @720-60p + Maui's "Jaws" also known as Peahi.

Last year I was hoping that I'd get to shoot this years season of massive waves on Scarlet at 120fps but still It's always a joy to witness the power of these massive monsters rolling in right in front of you..

Shot on the Panasonic GH1 + Hack @720 60p <----arrggghhh 3k + !
Glass is an old Nikon 120-600 which is 240-1200 on the GH1.. I guess it would be around a 480-2400mm on Scarlet 2/3rds ?.. Anyways, hope you enjoy

Crazy waves! The footage looks pretty blocky though... Is that because of the compression?? Are the mts files like that?
 
maybe my compression skills? definitely blockless before compression.. I set it to 10mbs single pass CBR.. Watching on YouTube HD is definitely better : )
 
aahhh man, why did you fade to black before showing what happens to the jet ski, looked like he was trapped in the white water. you got to show what happened. heheh cool vid, I was surfer for years, then got married and had kids, well.... you know the rest. lol

Muhahahaha, naw, he got out of there, but you could hear the crowd cliffside "ohhh-ing" and "aaaahhhing" for him.. Many a ski have wound up on the rocks....
 
Excellent video. I can't believe they made it out of that spin cycle. If you need any help with encoding it properly just let us know. You should be able to reduce the blockies dramatically even on youtube. Keep posting though. You have some real high quality content there.
 
Thanks, kprince. This brought back memories from last year. Please upload to vimeo. Youtube doesn't do this footage justice.

I'd love to learn the secrets to high quality encoding! Please let me know : )

Was the youtube file the exact same one that was uploaded to Vimeo? The Vimeo one is not perfect but it sure is a lot better than the youtube one. Vimeo must be uping their bandwidth lately because youtube had caught up with them for awhile.

Let me download the file you uploaded to Vimeo and see how it was encoded.
 
Hi kprince, How are you handling your AVCHD files in post? The Vimeo clip looks very sharp, I'm still having problems finding the best way to work with AVCHD in CS4.

yeah for the Vimeo I just changed to VBR 2pass @ 20mbs .. I'm still very new to encoding and how to get the absolute most out of it..

Do you want to encode at the highest bitrate possible to allow the next site more information or does it matter? These are questions I ask myself..

Now that's what I'm talking about! Took the time to download the original file and quality is spectacular! Reminds me of the opening scene of Billabong Odyssey (except in the movie Mike Parsons was in for a real chewing).

For this type of footage I think GH13 is still king. Even with the awesome alias-free telecon mode I don't think GH2 can compete with its measly 17 Mbps bitrate in 60p modes, especially so if final firmware lacks b-frames as it did on prototypes.

I agree : )
 
kprince: I loved the video. So powerful I just had to re-watch it several times over. Well done.

Now, I would dearly love to know how to do quality compression too, ideally using CS4.

And why/how is it that some videos posted on vimeo seem to look incredibly sharp, yet only have a data rate of 2-3mbps per sec ?

I usually compress in After Effects, which only offers a single pass. I have tried exporting to Media Encoder, but doing a 2-pass seems to take an inordinately long period of time relative to a single pass.

I guess this is a topic for another thread, but any pointers would be much appreciated.
 
The key to making low bit rate streaming video look good is to zoom in and try not record moving subjects. When you zoom out you end up shooting a wider field of view with many more objects in sight. Compression begins to struggle when it cannot find similar pixels to treat as the same.

When you zoom in you usually reduce the number objects in view. This allows you to fill the screen with similar colors but still retain details for very small and defined objects. The compression will be able to do its job much better when the image is more uniform.

If you film something like moving water then the pixels are constantly moving. This drives the compression algorithm crazy. You can see it even in the Vimeo version. The best thing to do is zoom in as much as possible to reduce the amount of water that is visible in the screen. However, it is not always possible to zoom in even further.

In that case it might be better to pan up higher to get more of the sky in view. The sky does not change as much as the water so the codec can allocate more bits to the moving water than if the whole screen is filled with water.

I always encode to the maximum variable bit rate my editing program will allow. I never go under 16mb/sec advanced profile H.264. However, I sometimes reduce the video down to 720p or even 540p in order to allocate more bits per individual pixel. You lose resolution this way but that is not as bad as introducing macro blocks due to over compression.

I use a cheap $60 video editor called AVS video editor. It works very well for simple transitions and cutting and joining, and some simple color grading and sharpening. It also comes with a AVS Video Remaker that allows lossless cuts and joins of ANY file type as long as the dimensions, codecs, and frame rates are equal for all of the clips.

AVS Video Remaker is great for those times when you want to upload several clips as one clip with minimal recompression.

I was zoomed into 1200mm : ) !! haha, yeah, I hear you though.. Would it then be best to compress at the highest possible quality as if compressing for blu-ray even though your just sending to Vimeo?? Doesn't Vimeo just compress to it's own defaults??
 
blocky city.... dop the original edit through a AVC mp4 two pass at 25mbits.... that will make love to youtube's encoder.

I like those fluffy things too! I want to buy one for my zoom and one for... well.... I'll keep that part private...

Hi ,
just wondering what settings you used in Ptool to get 60p. I have a pal model, and I have tried and failed several times to get 60p.
I would be very thankfull for some instructions there :)
thanks
