Hi guys, i need help from the gurus here...

I own a panasonic lumix zs3, it records video as avchd lite (according to panasonic at 59.4 fps), the problem is that some artifacts appears when i tried to edit the video on sony vegas pro 9, some artifacts like theses:

But those artifacts only appears on the pc (editing on vegas, playing on vlc), but when i play the videos from the camera, no artifacts can be saw.. i dont know what to do, heres a link with more about this problem on another lumix camera having the same issue and same video specification like my zs3:

Any help about this would be trully helpful! :)

im trying to make a video from 2 cameras, and those artifacts are making the video look pretty awful!

We'll be better able to diagnose the issue if you can upload a short sample of video shot with the camera in the same mode as the problematic clips. MediaFire is generally a good place to host such samples.

Btw using total media theater (on the original files) i cant see any artifacts, but with windows media player, media player classic, vlc, and on vegas pro 9 im able to see those annoyng artifacts!

AVCHD places its streams within a "transport" container...

And Panasonic specifically in MTS files ;)

All they do to get 60fps is insert a double frame reference in the stream (you can confirm identical streams by walking thru it frame by frame in AvSP with Avisynth) ..

As for the artifact, it's the decoder being used ... for Avisynth bring the MTS in via DSS2, FFMS2 or AVCSource ...

There are a heap of reasons that commercial editing software is crap, you have found one :P

yeap that was my bad (i used the video from vegas, so no m2ts), i was cutting the original video on tsmuxer, but.. i cant see any artifacts now! the only thing that changed since yesterday on my computer, was getting the new version of bdrebuilder but i dont think that make the video works without artifacts!

And yeah 7ekno its "60 fps" but in fact its only 29.970 with double frame rate reference.. how can i change the decoder? (i still want to edit the videos on sony vegas 9), all you can tell me will be useful, thx for all!

yeap that was my bad (i used the video from vegas, so no m2ts) Use DGSplit to cut the original m2ts/mts file and upload that.

And yeah 7ekno its "60 fps" but in fact its only 29.970 with double frame rate reference The sample you posted is 1280x720 @ 29.97 *WITHOUT* any repeat flags, i.e., no "double frame reference".

If you decide to post a sample, use DGSPlit rather than tsmuxer for cutting, in order that the original stream is not modified in any way.

Anyway, it appears you have a player problem and nothing wrong in the source file.

At the top of that link it states its a "decoder" issues, specifically for that blogger it was a VLC problem (which is typical) ...

By-the-way....

AVCLite does not support MP3 audio streams. It supports either AC3 (Dolby Digital) or linear PCM audio streams.

yeap i know... i was only replacing the audio (ac3), cause i have a better audio source, it was only a test, i was rendering a mp4, but as you can see on the pic, decoding the video in vegas 9 (the original video source), will make some artifacts appear on the new video, dont know why!

The blocking is the DECODER (aka Vegas), the "purple lines" are a limitation of CCD recording being aimed at bright light! To get rid of the blocking, render it to some other format that Vegas supports properly (something like Huffy lossless AVI, etc) via Avisynth using the above decoders that work ... To get rid of the purple lines, use a decent filter (Avisynth has CNR2 that works if the lines are only on a couple frames, no idea if Vegas even has a similar filter) ;)

Conspiracists may also note Sony may not want you buying Panasonic AVCLite cameras when they have their own :P
