vimeo question

I was just fooling around today with my canon XH A1 and letus extreme. Shot some footage because i wanted to play around with RGB curves in premier pro cs3.

Got a look that i adored and exported it with the settings suggested by eugenia at vimeo.com

captured the file, and played it back. Everything looked great, except that whenever there is quick motion, you get these horizontal line artifacts going through the entire image.

does anyone know how to fix this, or is thi common with vimeo?

thanks!

I am quite sure it is your display that is causing these lines, not the video. I've got the same on my notebook display.
 
hmm, that is very bizarre,

i have played it back on both my BenQ LCD screen, my HP CRT monitor and my lady friends mini CRT, all three of them display these horizontal "breaks" when there is quick motion in the footage.

look between the 36 and 50 seconds mark, as it pans across the large glass lamp on the floor and the picture frames. Much easier to see if you maximize the screen as it is very noticeable there.
Which brings me to my next question. The wall during those few seconds is very blocky. I know that is due to the low exposure but also my video seems to be slightly more blocky that what i see from others footage,

phil, would you mind sharing your export settings? i currently have it at
1280 x 720, progressive, square pixels, CBR 5mbs.

Click to expand...

i export at mp4 h264 720p 4500kbs

tried on different computers and all fine!
 
i don't undersatnd how noone is seeing these horizontal artifacts. Its like lines break through the image as it's refreshing. grr, wish i could solve this. hehe

You could try to switch the frequency of your display. From 60Hz to 61Hz for example.

could be a refresh rate problem. Because it looks more like the horizontal break is a cause of some sort of refresh rate issue. Although i have no clue how to switch a frequency, didn't even know you could on these monitors.
 
I've seen the lines too.

Well, it is indeed very limited to change the frequency. I can choose between 60 and 61. I guess your are on a windows machine. Right click on your desktop and choose properties. Go to "Settings". There you choose advanced. Somewhere in there should be the screen refresh rate for the monitor.
 
i guess im curious to know why i see these lines on my video, but not on any of phil's. I don't have this issue with the mp4 file created. Perhaps it has something to do with the compression vimeo uses.
 
IMHO, the file you upload to vimeo has to be of higher quality than the recommended specs.

Vimeo re-encodes the clip into a flash video, I think, but the better your source video is [the file you upload], the beter the streaming-Vimeo-version will be.

For a 720p clip, at least 6-8 Mbps, h.264. 2-pass.

Hope this helps.

P.S. Actually the vid looks fine, with a higher-quality source, the blockiness may be reduced.

What lens?
 
Just now I understood what lines are you talking about.

Nothing to worry about, IMO, it's from the monitor refresh setting and the vimeo player. it's not inside your footage.

I like the clip, for "fooling around" it looks pretty damn good.
 
thank ya:)

I have been working my butt off on learning how to use curves as opposed to linear blacks, mids and whites. It's turning out to be much, much, much more accurate and powerful than anything i've worked with before. I believe i am coming close to nailing the film 'look' in terms of skin rendition, colors and range. Man curves rule.

the best example is when I'm shooting out the window, looking out into a park. Notice the softness of the highlights and bright areas. Every time I see it i think film and not video, it's great. Everything from the green'ness' of the trees, the dark blacks that have a slight hint of blue/green, the nice saturation and the soft highs/highlights.
 
the only tradeoff of using curves as opposed to the old way, is rendering time. oh boy is it ever long for HDV.
