Progressive encoding?

[markk655]

Does VS11+ do progressive encoding? I am new to VS and couldn't find the option. I didn't see it in the user manual. At this point I only have the trial version, so I don't have the help files.

Thanks!

If you are outputting to AVI or MPEG then use custom settings, then under options > general tab, select Frame Based.

Thanks. I guess I was doing that since the other options were interlaced. But at least now I know what it does!

hehe I don't know why they insist on using such technical names. I didn't find out what any of them meant until reading up on the difference between interlaced and progessive lol.

OK. I am completely stumped.....

I am a newbie in AVCHD editing (I guess almost all of us are ). I am using footages from my Panasonic HDC-SD1 as well. The camera records in 1440X1080i format so the video is interlaced.

I can play the file in PowerDVD ultra and Nero showtime and with de-interlace option set to BOB, the video is quite acceptable.

When I import the clip into VS11 plus, I see obvious effects of the interlace format AND ghosting effects on the clips. This is probably due to the AVCHD interlaced format issues.

However, when I tried to export the clip (via batch convert or create video file), and select a progressive format (mpeg2 framebased), the interlace is gone but the ghosting of the clip remains. Is there anything possible to do about this? Editing AVCHD clips and re-rendering clips based on AVCHD to other formats are practically useless if this cannot be fixed......

Please help!

PS. I am pretty sure it is a problem with the encode that ULead uses because I tried recoding the stream using Nero vision and the resulting clip does not have ghosting.....

Just to make sure we are talking about the same thing...

1. ghosting would appear in a fast moving object (say a person clapping hands or a tree waving in a breeze) and then you see a blur? I thought AVCHD was supposed to be much orse than DV in terms of these motion artefacts. I still bought into the club anyway!

2. interlacing effects. I understand the principle, but what artefacts do you see in the video?

I agree with you. We are all just starting out and I guess we have to blaze our own trial.

Are you editing the AVCHD direct or editing the HD-mpegs? How does your computer perform while editing or during playback?

I also seem to recall reading something about square pixels or something for the SD1...But i have to admit, I didn't pay much attention and didn't think much of it until I saw the parameter in VS11+. Thoughts?
I have a feeling we are all in the same boat.

I had the Sony SR1E before and the Sanyo HD1 prior. I would say the SD1's video quality is definitely closer to SR1E (not quite there yet) but much better than the HD1. Pixelation wasn't too bad with the SD1.

In terms of ghosting, yes, the effect is quite obvious especially if I pause the video. On fast moving objects, they would seem to have an residual image of them about 0.1 sec before (couple of frames ago). I can clearly see it when I pause the resulting video on cars moving and I am talking about typical city traffic which is not that fast moving.....

The ghosting seems to be somehow connected to the video being interlaced. To prove it, I can play the same source clip with no de-interlacing (in PowerDVD Ultra and Nero) and I see the same interlace (alternate lines) and ghosting effect. When I turn on BOB de-interlace, both interlace and ghosting are gone.

I am speculating here but I think that the Ulead Mpeg decoder/encoder is having problems with the AVCHD format. I tested this idea by transcoding the same clip with Nero Vision with the same settings (resolution, frame based/progressive) and the resulting clip does not have any of the ghosting that are apparenti in the clips resulted from VS11 plus.

It sorta sucks because I think Nero gave me a better quality resulting clip in this situation but I can't get it to recode to WMVHD.......

Has anybody heard anything new about the deinterlacing / ghosting problem of using VS11+ with AVCHD clips?
