I think it depends on how your source records. my hv30 does upper field first for interlaced.

I just use mjpeg B all the time, never messed with A B comparison.

Please, give me advice.

I am now using CS4. I thought, no problem, and use the same settings:

My camera is the XH-A1 van Canon, 50i.

My settings for export are:
format: Quicktime
Videocodec: Motion JPEG B
quality 90%
formaat: 1440 x 1080
Framerate 25
Upper first
aspect: HD anamorphic 1080 (1.333)
Render at maximum depth is on

After this my HD-file is from about 230 MB resized in about 49 MB, and very bad in quality. I can't find the difference in settings between CS3. Please help.

Normally after this process I used MPEG-streamclip for resizing.

Settings seem ok, apart from the frame size. You have to go to square pixels (1920x1080, aspect ratio = 1) if you switch to mjpeg to maintain full quality, if possible from the m2t file directly or after just one HDV export of the edited m2t-clip in order to avoid quality loss by repeated compressions.

Not sure if I got this right: Normally your file size should -unfortunately- increase 4 or 5 times by going from HDV to mjpeg/mov.

I don´t know CS4. I am using Streamclip for encoding HDV to mjpeg/mov. Works perfectly, but you gotta purchase the mpeg2 component for Quicktime or try with free QT alternative to be able to open the files in Streamclip.

Good luck,
Stefan

Thanks for your help. The file is now 20MB bigger, I suppose from the square pixels I used now. But, it's still too small, and the quality is too bad :(

Isn't there anybody with CS4? I really have a problem now, and so much to render :(

Not on CS4 yet. And your settings do look good. Would love to help, but sorry, no idea. :(

Should be up and running on cs4 in a few weeks. Not sure if it is worth it... does do AVCHD clips, and my sister inlaw has one of those cams. We shall see..

Ok. Thanks to all. I have a really serious problem now, many to render, but impossible to convert it to quicktime full size.
When there is somebody with the same configuration... please help.

How about rendering an uncompressed avi 1920x1080 in CS4 and converting to mjepg/mov with Streamclip until you have figured out the solution? You don´t need to purchase anything in this case, just dld quicktime player and streamclip.

Please tell me... Why my clips rejected with message "An undetermined technical error has prevented the clip from playing" if my clips was MOV/PhotoJPEG (1920X1080 px /square pixels/ 100% quality. And after submition preview image is not created

I don´t know how exactly the parameters are with CS4.

Uncompressed avi clips as intermediate files can have any frame size, which would be 1920x1080 for HDV as this is the correct size for display. These intermediate files will be pretty big of course so you might have to encode them to mjpeg/mov one by one and delete the avis afterwards.

This could be a temporary solution until you have figured out how to encode your original HD clips directly to mov with CS4. No help available in Internet on this, maybe in an Adobe forum?

Cheers,
Stefan
