Gints you bring up a good point. For me to watermark I have to bring the clips into FC and that will compress the clips. I have not had enough time in the day to shoot clips that do not produce dollars. So I think holding off on sending compressed clips is my move for now.

Gints you should shoot some clips and if you don't own a Nano rent one you will not want to bring it back.

When I am back from this trip on the week of the 9th I can make time to shoot some clips just for a test unless you find someone sooner.

As soon as I get my HDV camera back from repair, I will be able to shoot some HDV vs. XDR parallel recordings. My HDV camera only does 720p though so hopefully that is good enough for you guys. I'll post up the raw clips for you guys to analyze.

I would be glad to send off these clips but I don't know how to water mark and not compress the clips. If there is a way let me know.

Bring them into an uncompressed format, add your watermark, and export in uncompressed format. The watermark will be 'rendered' onto the frame, but no compression should be happening.

Thanks Greg I will give this a go now.

This seems to work.

Dan Clips on the way.

How is it possible to add data to a compressed frame without decompression, addition and recompression? Is the watermark added with a short duration so that only a few groups of frames is recompressed?

Not sure Gints but I have given it a try and will send to Dan so at least I followed through. If it is not what he wants I will shoot something when I am back from a week on the road. On the road this time it is not my gear I am shooting with so not able to pull clips.

Paul, if you would like to use a web server for faster delivery to Dan, please use the ftp server account I sent you. ( I think I sent it to you.)

Dear Gints,

Paul has already started sending the files directly to our server.

Some of the uncompressed files are huge, as would be expected.

Paul mentioned that one, 7-second file, was 1.7 GB.

Paul,

Thanks for your comments. I am intrigued by the Nano's high bitrate recording especially after I observed the differences between my previous work with Sony Z1U HDV and new work with Sony EX1. Since there is almost no material available to convince me that the Nano provides a visual benefit over my EX1, I'm having fun searching for other high-tech justifications such as "crash cam" via HDMI, high frame rate stills, buffered cache, etc.. But, the $3k will only be spent when the visual results are in.

Gints

Thanks, Dan. Large files are no problem with us. Are they uncompressed for the sake of the watermark? Frame grabs from both streams would be even more useful. We want to see actual target files.

I will be posting original files, straight HDV and straight out of the XDR. No watermarks, compression or anything else.

The files will be reasonably small.

Sorry guys to send such big files but it is the only way with footage I don't own. Last file is finishing up now. Hope it show what people are looking for to compare. It sure does on corrected monitors off the original files.

Gints no FTP info sent my way.
