AVCHD transition blips in VS Pro X7

[lata]

Hi Mark Lis

Thanks for those samples, it is possible that the files were still uploading when I tried to download, maybe should have tried later.
Good that you seem to have removed the blips from those transitions.

As I mentioned your video properties are identical to the ones I use with the exception of being NTSC, I use Pal.
Panasonic did produce a video version called Panasonic Lite, I guess tweaking their codec to match their needs.
That did cause some issues for the video editors, so many different formats out there.

In addition to setting the project properties manually, create your own template using the Movie Profiles Manager – use the Add function will copy the properties of your video file.
You can then use that to render when another video is first in line, Or creating a slide show to your video files properties

What I see is a frame that is missed right at the very end of the transition.
I can't verify if project settings is related as I did some test projects with "uncommon" settings and I don't recall that.

It has not "continued to do so." Even though I now let the program set the project properties automatically, some blips after transitions
still occur. Grrr... I had some significant hope that upgrading from VS7 to VS8 Ultimate might make a difference. But, in short, it has not.
I think no one has explained technically speaking, how the setting of project properties can cause a post-transition stutter. Therefore, if the artifact seems
to disappear after such setting, I would now think it more a temporary coincidence than anything else; which means we still don't have any real solution.
Using my 30 day support window, I have (again) contacted Corel about this. As usual, they badger me about my version, my build number, my OS, etc.
I responded that the problem has been going on for years and is not just with me. I also included links to this forum, to demonstrate the point. If they end up asking me
about my model of computer, then I think we are finished here, in every sense of the word.

The "blip" has never (quite) disappeared, as was indicated in my last post which reported on the blip's return,
whether or not the project properties are set in advance.

I am convinced this is a Corel product defect, since I have experienced it on and off for 6 years, using 3 different
camcorders, 4 different computers, and 3 versions of Video Studio. Others here have encountered it as well.
I have been after Corel on this, and I hereby report the latest development:

"Using those prefabbed clips, showing the instance (blips) you are reporting, we have been running tests to recreate the issue. As it stands, we have been able to reproduce the situation and we will be escalating this to our engineers for further investigation and testing.
The downside to this, is that I do not have a definitive date, if and when this will be fixed. It could be a matter they are already aware of and plan on implementing the fix in the next version. Or they could offer a fix for X8, I simply do not know."

"Thanks for letting us know about this issue. Our engineering department is assessing it to determine whether it is a valid product defect. This process can take some time. When the issue has been addressed, we will send you additional information by email."

Hi Mark
Its good that Corel have managed to reproduce the blips, a bit of a pain to purchase X8 to get free support to prove that.
If the next version (X9) fixes the issue then they should provide a hotfix for X8 otherwise I would expect a free upgrade to X9 given that they know the X8 has problems.
New versions of the program are usually released in February, so if that is the same this year I would expect X9 to be ready for release so they should be able to say if X9 has the same problem.

Maybe worth asking Corel Support that question.


Project Properties – a short explanation

Video properties vary depending on the type, some record to 29.97 fps and others to 60P
If the project properties are set wrong then the timelines cannot display all frames, or may / will add frames.
It could be that the project properties are set for 25fps when using 29.97, now 5 frames per second will be dropped from the timelines.
Adding a 60p video to a 29.97 timeline will drop 50% of the frames.
Adding a 29.97 video to a 60p timeline will duplicate every frame, adding 50%

There is also the aspect ratio to consider, so setting the frame size correctly will help in displaying the video correctly.

The option to Show messages will prompt us to set the project properties, at least when using recognisable video formats whose properties can be used for project properties.
Getting the project properties to match does help with Smart Render as the program can compare changes / edits within the timeline.
This makes Smart Render more effective.

I will ask Corel about a hotfix for VS X8 or free upgrade to VS X9, should VS X9 be a blip-less edition.
But, since their engineers have only now begun to seriously investigate this issue, and VS X9 is probably
due for release next month, I would rather expect X9 to be as blip laden as was X8, X7 and X6.
I really thought this problem was solved as I began to ensure the project properties matched the video properties exactly.
Not so fast though. This seemed to be a fix for awhile; 'for awhile' meaning it probably was never a fix at all.
Whether I used smart render or not; whether I let the program match the project properties, or set them manually,
I would still get that damnable blip/stutter effect after (sometimes before) a transition. After much experimentation,
I have concluded this is a Corel problem, and it is Corel who has to fix it, one way or another. So...now we wait for that day.
