Pixilation of DVCAM in EDIUS Pro 7

[spurfilm]

A couple of years ago I edited a PAL job in EDIUS 5.51 at 1920x1080 50i, which included both HDV at 1440x1080i and some DVCAM material which was 16:9 720x576i. EDIUS did a good job of upscaling the DVCAM material to HD. On my 1920x1080 external monitor it was not very sharp of course, but there was no aliasing.

I have since upgraded EDIUS to Pro 7 and moved my HDSTORM card to a new 64-bit computer (details below) and a new graphics card.

I have reopened the same PAL job on my upgraded EDIUS Pro 7 computer (at 1440x1080 50i) to make some adjustments for the client. I am surprised to see that the DVCAM material is now heavily pixilated in my 1920x1080 external monitor (fed by HDSTORM) and also in EDIUS at full screen preview mode.

I have looked at the same DVCAM clips in Windows Media Player at full screen size and although they are soft, there is no trace of pixilation or aliasing.

Can anybody please help me understand why EDIUS is introducing this pixilation and aliasing? Have I missed a setting somewhere?

DV usually does not look good on a monitor which is 1920*1080, i notice this when output via HDStorm. I ignore it as it ok on output to media
Is the final output ok

Hi, you are correct. It looks reasonably acceptable after rendering to GV HQ Fine, and playing on Media Player. I am sure the pixilation was never there on the monitor before my upgrade. It's rather disconcerting for my client. But this will hopefully be the last time I'll see any SD DVCAM material, so it's not a long-term issue. Thanks again.

Are you using the thunderbolt card for graphics?

No. Just for external media storage - eg: LaCie 20TB 5big Thunderbolt 9000378EK.

Hi Mate!

I would check in the project settings that you have lanczos 3 high quality selected in the scaling options. This is a new option you wouldn't have had in 5.51 and it will do a better job on scaling your DVCAM material to HDV frame size. It might not fix your pixel problem on preview but your final output should look much nicer. The setting is also available in the layouter on a clip by clip basis.

Brilliant! Many thanks! Rick

Dave, in actual fact it definitely DOES fix the pixel problem on preview via HDSTORM. I clicked between the various resampling options and watched the difference. Really amazing. Lanczos 3 high quality is absolutely the solution. Thanks again, Rick

Glad it helps.
