resolution query

I just uploaded my first clip but very disappointed with the quality vis-a-vis others with similar data. An HDV clip shot with a Canon HV20, It was exported from my editing program with JPEG PHOTO, 1920x1080 at high quality. Am I seeing a low-res version that's later bumped up once this is curator-approved?

No, that is what it looks like. I agree, they don't look that great on the preview.... I have an HV30 and feel the same. I use MJPEG for interlaced. I think it is just how the compressed video from the hv's look.

Thanks. So other cameras simply yield appreciably better results?

You will no problem with the HV20, I makes excellent HD video. Any quality problems will be operator error not due to cameras ability.

I'll have to upload some other clips and make an overall appraisal. But you're sure there is no difference in quality or appearance post-approval? The clip I'm awaiting looks badly down-resed, yet looks perfectly sharp in my editing program timeline. Do you convert HDV captured at 1440x1080 back up to the1920x1080, as I've had to do in order to restore 16x9 aspect ratio?

Don,
I do not see any problems with them on my computer at full res. The problem seems to be when they are compressed for web display. It seems it happens worse than with other more expensive cameras.... I don't know why.

David,
The clips you upload will be the exact clips the final user buys. They don't reenconde those or change anything there.

Thanks for the input. A second clip I just uploaded looks more acceptable. I'm assuming, then, that not all clips that pass muster in an editing timeline can handle this sort of compression, especially if they have a lot of contrast and movement, as is characteristic of my first clip. Anybody else find themselves rejecting material once they get a look at it on pond5?

Sometimes I have the impression that the preview of the finally approved clip looks better than that one you see directly after uploading. But then, I ask myself why would P5 encode the same clip 2 times? Probably that´s kinds of an optical illusion... I think that previews are encoded with a reduced frame rate and a constant bit rate. So previews of clips that are rich in colors and have high motion will generally look a bit worse than still shots with just a few different colors (like a calm sunset.). You should compare your clip with others that have a similar subject.

For the original clip, you overcome the color/motion problem by choosing a quality level of the mjpeg or photojpeg codec instead of a fixed bitrate. "Difficult" clips will have larger file sizes, but they shouldn´t look worse than shots of e.g. a blue sky with some birds.

Cheers,
Stefan

Here's an explanation on the clip viewer. I also asked the same question to Marcus a couple weeks ago. He answered my concern and posted this thread for all to see. Hope it helps.

Would love to read thread, but selecting this hot link only takes one back to the home page. Can someone help?
