HDV smartrender problem

[luc]

I use MSP 8.10 SP1
I edit in HDV PAL

when I use Smartrender when I create an output HDV mpeg file, I notice some slight artefact just after each effect (e.g. after title overlay or after transition effect). The software seems to have problem in joining properly rendered sections and non rendered section.

I have no problem when SmartRender is not ticked, but all my files needs to be recompressed: so it takes longer and the quality is reduced due to the recompression of the native files.

Is this a know problem ?
Thanks !

I experience the same problem when rendering a final video from PALDVD to PALDVD. Even if the source files and final output is the same in properties, I experience the same artefact after transitions, titles, etc.

What would be the solution...

I'm not qualified to answer, as I don't use HDV but, generally, MPEG is not really an editing format, it's a distribution format. The problem is probably because the artefacts are a result of changes on a P or B frame.

Have you tried converting your raw footage to a no-loss or low-loss format (only I frames), editing and then re-converting to MPEG?

This must be a PAL problem because I edit the same in NTSC (smart render on) and do not see artifact problems. In fact I very rarely ever work with anything other than HD mpeg and have never seen what you describe.

Can you describe the artifact?

Or can you post a screen shot?

Also, when you render out your timeline, have you deleted all "temp/preview" files?

I've not done enough HDV editing to be certain, but I suppose it's possible that multiple previews might have a cumulative degradation effect on edit points that might be avoided by clearing the temp/preview files prior to the final render.

Jerry,

It is more like an image freeze (more visible on objects in motion) so it is difficult for me to post a screen shoot. I will try to post a video sample (rendered with and without Smartrender to see the difference)

Clearing preview files does not help.

Thanks for your help.

Please find a example of the difference between smart render and not.
It shows an artefact after the crossfade:

Wow.

That's ugly.

Have you reported that to Ulead technical support?

Hi
I ran into the same problem with Videostudio10 and the bug still exists in VS11+.
However, I have seen that Ulead has release a V8.2(SP1) update for MSP and in the release notes they mention that problems with smartrendering are solved.
@Luc:
if you still visit this board, did you report the problem to Ulead support at that time and could you please tell me what they answered to you?

@everyone:
Can someone please confirm whether this problem is fixed now or whether it still exists?

Thanks and kind Regards

I have experienced the same problem with NTSC HDV. Not on every transistion, but present on many. About a second after the transistion completes.

Otherwise, MSP8 would do a pretty good job of creating an edited file for MF6 to burn to HD DVD.

Inbetween I could test MSP8.2 on a friends computer and I can tell you:
THE PROBLEM STILL EXISTS IN VERSION 8.2!!!
I have tested with SD-mpeg2 files from my Panasonic SDR-S100 camcorder(no HD) and I could see distortions/glitches at the end of a transition. The problem immediately disappears if I turn off smartrendering. The same problem is in Videostudio11plus. I hope Ulead will fix this terrible bug soon(at least in VS11) otherwise the Ulead products are useless for all HDD or miniDVD camcorder users.

I agree.

It's a terrible bug.

The problem lies with MSP and all the Windows XP (32/64 versions) which do not handle Mpeg HDV correctly or any high quality media for that matter. Solution is XXXX Express which allows very good frame editing for HDV when used with the correct hardware. Vista is leaps ahead of XP which handles HDV video almost perfectly so when the competition are up to speed with Vista the OS should hopefully be a match for the Mac, which all professional programs are available for.

Vista 64 bit programs are starting to appear and the improvement is very noticeable and a step closer to the Mac OS. If I¡¦m right in thinking stands at only two or three if you count the current Intel OS platform. I have lost count of all the windows versions so far and still pulling my hair out even with OEM equipment. My seven year old Powerbook G3 still holds its own against Vista only having to do one install upgrade for each OS for a dual boot system that¡¦s the benefits of a hardware software manufacturer, it does exactly what it says on the box.
