Svyatoslav, can't check out your clips since I'm not on FCS2 but have been really wanting to see some HV20 Intensity footage. I'm wondering if you could post some footage in another codec such as Photo JPEG (quality set to 75% or better)? I would check out http://www.mediafire.com/ for free file sharing also, it doesn't have the limits that Rapidshare has.

Ok! I will do it, does not think although, that Photo JPEG is a good codec.
Sense was exactly in that, to show work of ProRes. Can it be better to save now without encoding?
Recently did a trick - created a virtual disk in memory and wrote down straight in it via HDMI by Blackmagic Media Express: UNCOMPRESSED.
I was shocked - 1G/s. Phenomenal quality.
Now I will give a grand-dad my Cinealta :) I will shoot the next commercial straight in memory by two HV20 and Blackmagic On-Air 2.0.

Wes, please, how you do it:
"Converting 60i to 60p
1440x540 effective resolution 60p footage can be extracted from a 60i 1440x1080 stream by de-interlacing 60i footage and preserving each field as an individual frame." http://www.vasher.com/v4/v4_more.php?id=98_0_3_0_M4

P.S. If interestingly, look here:

Svyatoslav, Photo-JPEG is a very good as long as you compress to a quality setting of 75% or higher. Good for posting high quality clips at reasonable sizes. I only suggest it because not everyone has FCS2. :(

If you shoot 60i you can seperate each field and make that into a frame, thus getting lower resolution 60p video from your HV20 (or any other 60i camera for that matter). Which is good for slow motion and other effects.

HV20 1/48 => HDMI => Apple ProRes422(HQ) => Motion JPEG 75%:

Svyatoslav, outstanding shot! The cigar smoke would really challenge the MPEG2 compressor but the Intensity capture just looks silky smooth. Great job and thanks for posting the clip. Was this in TV mode?

Thanx. Yes, Tv mode 1/48.
Only one trick: I used a polarization filter, to reduce the specks of light on the skin.

This is great to see! Proves how much nicer pure 4:2:2 is compared to 4:2:0.

I've captured raw 4:2:2 out of the HV20 too, but used a 35mm adapter, so it's nice to see this uber-sharp pure footage. Thanks for sharing!

Very nice. Really shows how badly HDV mucks-up what the sensor is capable of capturing. Just reinforces that I'm going to have to shoot tethered. :-(

PS. Do you think you could post an uncompressed, full-res still? (PNG, TIF)

I will shoot movie specially for you tomorrow.
Uncompressed :)

Here a few movies by duration of 1s. Written down in RAM and HDD by FCP and BME(Blackmagic Media Express). UNCOMPRESSED. It is initial files and it's necessary to do pull-down and deinterlacing. Weather terms are bad although, but quality is visible:

I hope that Canon and Blackmagic will give me a medal :)))

The detail is just phenomenal. So clean. If this camera had true manual controls, it would be an indie dream machine.

Is it possible to record to tape at the same time? It would be interesting to see the same shot both ways, especially a scene with intense color (like the red shirt of your first post or the blue car I've attached) to compare 4:2:2 with 4:2:0 subsampling.

Svyatoslav Pylypchuk
October 3rd, 2007, 07:28 PM
It is an exact remark. I will make an effort do it in the near time.
(you did a very large magnification:)

Joseph H. Moore
October 3rd, 2007, 07:44 PM
Yeah, it's a 200% enlargement. Just so that it is easy to point out the visible artifacts of 4:2:2 sub-sampling. (It should be much better than HDV's 4:2:0 sampling when recorded to tape.)

It very strange, but they are not written down simultaneously on tape and in a file, but I will try...

Svyatoslav, thanks for your contribution, I'm following this thread with plenty of interest.

Best regards

Svyatoslav,
Are you sure? I don't have a way to record HDMI, but I have monitored HDMI and recorded at the same time. The camera shouldn't care.

Certainly. I had because of synchronously under a management from a computer.
