Distortion after inserted transition - Pro x2 - HF100

[Przemek]

I tried to record a short test film - about 3 minutes - from my HF100 Canon camera. Imported the clips into Video Studio and:

1) I have created a short AVCHD file (this file was created with the option - "The same as the first clip") - (Share - create file) and the quality is fine, however, after each transition effect ( I chose 3 different ones) there is a short distortion in the film - about half a second - a short jerk.
I recorded the same film but without effects and everything is smooth. Any ideas?

2) Also, I have another problem but this time with the creation of an AVCHD disk - I recorded the same short film and the quality is definitely worse than that of the above mentioned video file (On the properties down the bottom I marked the best possible options - 18000, best quality - 100%, etc.) The quality of the AVCHD disk is as if the film was made on 24 frames and not 60 frames per second (or slightly worse). The jerks after each transition are exactly the same as on the, above mentioned, video file.

I've been experimenting with my new Video Studio X2 for 2 weeks now, and I watched the effects of my editing on PS3 (both hard disk and AVCHD disk). I would like to add that I've been using Video Studio since version 7 (previously editing DV video).

thanks in advance for your help

Welcome to the forums!

I am afraid the distortion after transitions appears to be a bug in the program. Quite a few of us have experienced it. See this long thread about it: http://phpbb.ulead.com.tw/EN/viewtopic. ... 014#167014

I encourage you to report it to Corel. That way they may be encouraged to work quickly on a patch.

As for your second problem, I assume you are talking about an AVCHD hybrid disk (i.e. AVCHD burned to a standard DVD). If so, my own personal way is to do the editing, and then instead of actually rendering that to a new AVCHD file, I jump immediately to the burning module: Share > Create Disc > AVCHD. This inserts the project file in the burning timeline. I then click on the middle of the three icons in the bottom left of the burning screen, and you will see a big window with the burning properties, which you can then adjust the way you want. Then I build my menu and burn.

Unfortunately, the distortion around the transitions will still be there.

Thanks a lot for the veeery quick reply!

I have already posted the problem with the transitions-distortions to Corel and as soon as I get a reply I will post it here.

As far as the second problem is concerned, what you suggesting (and I've followed your advice from previous posts - Share > Create Disc > AVCHD) I followed it in my trial editing. After editing and inserting the effects (text + some music) I jumped straight to Share>Create Disc etc. In the options in the middle I put the best values available, i.e. 18000 + 100% quality, and the final effect was worse than that I got from Create File. In fact, just a few minutes ago I was comparing the two videos (in fact 3 - one with effects, one without and one from hybrid AVCHD disk). As I mentioned before, I've been experimenting for quite a while (on two computers). I do not give up easily, but I'm a bit lost now, and I do not know what to try now.

While I still produce AVCHD hybrid discs, I really only do so these days as a back-up. I have my PS3 networked to my computer, and use either WMP or Nero Media Home as a server, which the PS3 can detect. That way you can play your edited AVCHD direct to the PS3 and then (presumably) onto your LCD or plasma HDTV via HDMI. The quality is brilliant!

Very good idea, I do the same (first tried do this via WiFi connection - it is impossible, ethernet is needed)

[Ken Berry]

Yes, I don't think the WiFi connection could keep up a high enough, and constant enough transfer rate to be able to cope with the high bitrate of AVCHD and HDV video... For clips under 4 GB is use a USB stick, or put it on a hard disk drive (formatted in FAT32) which I connect via USB to the PS3. Works just as well. And you may not be aware that if you burn a high def (HDV or AVCHD) file to a DVD as a storage/archive disc in a VIDEO folder (required by PS3), and put it in the PS3, it will play it too... So you can use RW DVDs for that...

I have just received a reply from Corel:

Dear Przemek,

After carefully reviewing this incident it is recommended that you call into our technical support center for further assistance. E-mail is an alternative option for technical support on resolving minor issues. Due to the nature of this particular issue, and the need for interaction, contacting Corel directly via telephone will provide you with a quicker and more tailored solution for the issue you are facing.

Please Note: A fee per support incident may apply when calling. For information on pricing and contact information, please visit:

North America - http://www.corel.com/support
UK - http://www.corel.co.uk/support
Other - http://www.corel.com/contactus

So, Corel has no answer to the problem yet. I will risk 10 pounds and try to find out more. Will keep you posted.

With regard to the second problem I had, i.e. the loss of quality in recorded AVCHD disks, I have partially solved it. My camera is HF100 NTSC model, and when I was recording an AVCHD disk, the template was for a PAL disk. It turned out that there is a degradation in quality while converting NTSC HD film to a PAL one. Now, when I record in NTSC (and it makes no difference for my TV) the quality is definitely better; however, it is still worse than the quality of original clips (straight from SD card from my Playstation or straight from the camera). It is not a big difference, but since I am quite a purist as far as quality goes, it is upsetting.
I tried NERO 8, but the quality seems to be worse than that from VS X2. I would like to stress that the degradation is really really small.
I record in 1920x1080, 60i, and the picture straight from the camera is excellent. Maybe somebody knows an answer to this problem? VS records 29 frames per second, and I recorded 60 frames on my camera, so maybe this is the reason...

Not really. The NTSC standard is 29.97 frames per second, with two fields to each frame - you might therefore call it 59.94i, which is pretty close to 60i.

I also reported the blip after transitions (and also titles). I received a different response than you. They asked me for some detailed system information and also two Vista error logs. I sent them the information yesterday and am awaiting the next response.

Hi everybody,

I've just spoken to Corel customer support. All thay could tell me was that there must be something wrong with the avchd codec used by my camera - HF100, and since this camera is not supported by COREL X2, I need to buy different software. That is really helpful and now there is nothing left, but to look for different software.

Does anyone have the same problem but uses a different camera supported officially by COREL (not HF100)?

[2Dogs]

Hi Przemek,

do your mates call you Prz for short?

I expect you were a bit non-plussed by the Corel response!

Strange too, bearing in mind the Canon HF100 is one of the best and most popular Flash AVCHD camcorders.

Ken recently stumbled upon something you might try.

Instead of putting your clips and transitions in the main video timeline, use the overlay timeline.

It's a bit of a pain, since you have to resize all the clips to their original size, but maybe there's some setting in preferences that can make 100% the overlay default size. (if 100% was the default, there might be a lot of confused first-time overlayers...)

Then do a test render and see if you still get the "blips" - and let us know the result.

Edit: preferences shows "fit to screen" as an option that can be checked for the default overlay size.

Here is the thread that 2Dogs refers to:
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=33869
And here are Ken's comments:

I just tried your experiment with X2. Disappointingly, neither method resulted in AVCHD which would play smoothly in VS on my Quad -- in either Clip or Project mode. (The original clips would not either... I do not use SmartProxy.) Both played perfectly in PowerDVD 8, however.

One potentially positive result nevertheless was that the new clip (made with3 clips and two crossfades in the overlay track) played back *without* the annoying blip which seems to follow transitions when using AVCHD in the main timeline... I may need to do more experimentation to establish this as repeatable with other transitions, though... Hmmm! Rolling Eyes Idea

And yes, in Preferences you can set the clips in the overlay track to full size.

I have the same problem with my Sony SR-11. Guess it must not be supported either.

[bankroot]

Very, very intersesting.

I wonder, which camcorders are officially supported by Corel and where this info is written ?
