There is no mistake if I create file without transition

Here are two files from my camcorder, would someone by so kind to test it in his/her CVS pro X2? (put the clips on timeline, use any transition, create file AVCHD PAL HD 1920 and see the result)

I tested with the two files you provided, and though the first one doesn't show too much motion, the artifact at the start and end of the crossover is clearly there. I also tested with some AVCHD files from my Sony SR11 and got the same probems. In one crossover I got no "return" but the moving cars got distortled (cfr Black Lab ref). Another thing I noticed was that with fast moving contents, about 5 frames after the return, I got one frame skipped.

When I first tried Pro X2 I was putting 1-second fade-to-black transtions between AVCHD clips from my Sony SR-11, but experienced the same problem that has been described in the last few posts in this thread. So I stopped using transitions. I hope Corel sees the need to fix this and other problems related to AVCHD.

That's very very bad news guys

How can Corel released videostudio with so big BUG

To use soft without transitions? No it is not acceptable for me
I hope soon will be some patch...

Fortunately I have the trial version for another 21 days. Of course I am not going to pay a penny for the program if this bug is not being solved soon.

I just observed another similar problem in an AVCHD file that was rendered by Pro X2 from AVCHD clips, with smart render off. I put small titles at the bottom of some vacation clips to identify to the viewer the location that the clip was taken. These titles are super-imposed on the video. (They're actually more like sub-titles). I am using the title that is in the 2nd row, third from the left in the predefined title library. This particular title automatically fades in and fades out.

Immediately after the title finishes fading out, the video flashes or jumps like an extra frame is being played, or maybe one is dropped. This looks just like the little blip that occurs after a crossfade or fade-to-black transition. This blip does not occur when playing the project from the timeline, just in a rendered file, or an AVCHD disc created from that file.

Has anyone else had this problem with titles?

Am I creating these subtitles correctly, by placing a title (one supplied with Pro X2) from the library into the Title 1 row of the timeline and then editing the text?

to dalemccl: I made title as you had described and have the same problem

It looks AVCHD users can use CVS X2 only for cutting clips

It is good value for money...

not to the end

For me, even this part of activity is unusable, due the jerkiness.

Is your original footage AVCHD 1920x1080 or 1440x1080. My question relates to a (maybe still existing) 1920x1080 problem with Canopus Edius New which was non existing with 1440x1080 AVCHD footage.

Hello,
I have the same problem with Corel VideoStudio X2 Pro as Efenstor and michal_h wrote. I have the camera Panasonic SD9 and I am using Full HD 1990x1080p or sometimes interleaved mode too.

This problem is very terrible for me because I spend my money and I don't want to buy something else now.

Is there some support way to Corel? What we can do? Wait for only?
Is somebody inside Corel Company who knows about this problem?

have you already solved the problem? or you still waiting for new patch?

Yep, like everyone else here, I'm still waiting for the patch. Interestingly enough, Pinnacle Studio has no AVCHD smart render at all. Clever move of them to avoid problems. Looks like there's no solution yet, processing the source files with Nero as I wrote doesn't always help, it's a too insecure method. Nero 9 also doesn't help. Decoding with DGAVCDec shows artifacts: http://neuron2.net/board/viewtopic.php? ... cf79b94f80. One more proof of that there are some "proprietary" bytes in the transport stream, causing all the mess.

smart render is not the cause of the problem because if i create file w/o smart render I have the same mistake

It is AVCHD 1920x1080.

I agree. I don't use Smart Render and get the same artifact problems with transitions and titles.

(I don't use Smart Render because I had audio/video sync problems with AVCHD rendered with Smart Render on. Turning it off solved that particular problem.)

it looks that avchd is one big problem for all NLEs

but acvhd cams will be soon mainstream so NLEs have to be improved
but do we have to wait another year for the next versions?
