I get flicker with VLC playing GH1 1080p MTS files? The video shows alternating bright and dark frames. What is wrong here? Uwe

VLC.

On Mac OSX Toast 9 / 10 from Roxio includes a video player that has near flawless playback. No idea if Roxio has something similar on PC.

Did you try this for the GH1 and 1080p?

My problem is that I did not find a demo version to test.

VLC plays GH1 720p just fine. 1080p flickers.

VLC plays any AVCHD file with constant decoding errors like below. Caused a lot of grievances about the quality of GH1 before it was sorted out to be a VLC bug.

VLC can handle the AVCHD files from the HMC150 just fine though. Btw. ffmpeg can decode the GH1 streams correctly so I wonder what kind of bug in VLC causes this because it's supposed to be based on ffmpeg too.

Toast video player (I only got Toast 9) plays the streams corretcly but it has got some kind of sharpness problem on my machines. When I transcode from AVCHD to ProRes with Toast the result is much sharper than when just playing with the included video player.

Martti,

do you convert your footage with Toast 10? What settings and what output codec?

I do - so far as my target with my GH1 footage has only been Vimeo / YouTube I've taken the lazy route of Apple Intermediate Codec for simple real-time in FCP. But it allows you to transcode to any Quicktime codec you have installed.
Will try to figure out a work-flow for PhotoJPEG / Blackmagic next week if work/life permits. I did some simple tests early in the summer and in my eyes Toast has the best AVCHD de-coder. Cineform files for instance looked better from Toast than NeoScene IMHO. However Toast doesn't deal with pulldown removal so guess that can be a bummer for NTSC, I'm luckily in a PAL land.

That maybe an issue. I have to check. But being able to view MTS files directly is nice.
