produced CD2 clip plays slowly

I've noticed that if I edit a clip in CD2 and then export it back to an un-Produced (un-rendered) video in PD 12 without first Producing (rendering) that clip in CD2, the colors and brightness are all wrong - way too bright and skewed toward the green end of the spectrum. The appearance when the clip is back in PD12 is nothing like its appearance before exporting it from CD2. I can't use CD2 with that color/brightness mismatch.

But if I first Produce the clip in CD2 and then hit the Back button, exporting it back into my (unproduced) PD12 video, the colors in PD12 are okay - probably indentical to what they were in CD2. However, the clip I've just exported from CD2 plays as if it were in slow motion, and it stops/stutters intermittently, as if there were a buffer over-run problem. I'm not surprised at that, since in effect I'm Producing that clip twice - once in CD2 and then again in PD12, when I Produce the rest of the video. But again, I can't use CD2 with that problem.

So - is anyone else having one or both of the two problems I've described here - color/brightness mismatch between CD2 and PD12, and slow, stuttering playback of Produced CD2 clips after they're exported back into PD12?

And - if so - what workarounds have you found?

Thanks - Bill Hansen Bill Hansen

Hello Bill,

Some of the points you've made raise further questions and are quite concerning. It would be really helpful if you could post screenshots showing the difference in colour between CDR & PDR.

I have noticed some slight differences, but not the extremes you're observing. Those screenshots would be a help. I've found the colour differences are less pronounced in the produced files. Remember that the preview screens of CDR & PDR are just that - preview screens. Do you have both set to Full HD?

Bill - that's not entirely correct. When you click Back in CDR, you're not sending the produced video - just an adjusted clip. If you've applied multiple adjustments, like any effects, it may cause PD (your PC) to slow down its response time.

Please take a look at the video I posted here http://forum.cyberlink.com/forum/posts/list/0/38855.page and see if it clarifies anything.

Thanks for your reply. I will send screen shots of a frame in PD 12, the same frame edited in CDR2, and then that same frame imported back into PD12.

I reviewed the video you linked. It's very interesting. If the color values aren't exactly the same after editing in the three different applications, the resulting colors are close enough so I couldn't tell them apart, even when looking at them sliding over the top of one another in your video.

You've used an exporting method which is much more complex than what I've done. All I've done so far is choose to edit a clip (I've done this on several clips, from different original videos) in CDR2, edit it in CDR2 until I'm happy with the colors, and then hit the Back button in CDR2 to send the clip back to PD12. This results in the brighter, greener clip (in PD12) than I saw after editing in CDR2. I have not done a final Produce of the complete video when it contains the clip edited in CDR2.

Separately, taken some clips from PD12 to CDR2, edited **and Produced** and CDR2, hit the Back button to send back to PD12. That results in color in the "new" PD12 clip which is close to what I saw after editing in CD2, but which plays slowly and stutters.

Sorry for the very awkward syntax here. I hope the meaning comes across. I'll try to post the PD12 and CDR2 clips later today, but it's a busy day so it could be May24 or 25 before I get to it.

Pix -

I stumbled upon what I've been doing wrong!! I'll bet a few others have made the same mistake.

I was adjusting a few things in PD12, then editing in CDR2 without removing the adjustments I'd made in PD12. I know it's not supposed to make any difference - CDR2 supposedly removes any adjustments made in PD12 - but tonight, when I took care to remove any adjustment I'd made in PD12 (set all values back to zero) before editing in CDR2, the results in CDR2 are quite good even after I hit the Back button and send the clip back into PD12. The colors and dynamic range are better than I can do in PD12.

If I export to CDR2 before I've done anything to the clip in PD12, I get the same good results when the clip is exported from CDR2 back into PD12.

My guess is that CDR2 does actually remove the adjustments made in PD12, but then when the clip is exported from CDR2 back to PD12, one gets a sort of "double profiling" - some of the adjustments which were made in PD12 mess up the exported version from CDR2. It doesn't look quite like a double-profiled still image, but I think something like that must be happening.

Editing in CDR2 is a much slower process than editing in PD12 because of the delay in transferring a clip from PD12 to CDR2 - and of course because only the more difficult clips go to CDR2. I assume much of the delay in moving the clip into CDR2 and back to PD12 would be gone when using the paid version of CDR2.

I'll play around with CDR2 for another week or so - but as of tonight, I'm very happy with it, and I'm pretty sure I'll buy it.
