Aliasing/twittering EX1

Use the “mpeg2 6.2mbps 1 pass setting” in the “DVD Fastest encode 90 minutes” folder and the dolby digital professional 2.0 setting for the audio

Great, I will try this.

Are you increasing the average bit rate for better quality and changing the frame controls in any way?

[Steve Connor]

depending on the length of the video I may tweak the data rate to 6.7 or 6.8

Thanks for this workflow. Image looks a LOT better then it did the first time.

Just to throw another workflow I discovered into the mix. Have you tried this?

Edit as normal in HD in FCP
Choose File>Export to XDCAM. This will create a BAPV folder with your project in it.
Launch XDCAM EX Clip Browser and open the BAPV folder
Choose File>Export>Raw DV
Use the newly created DV file to create your DVD using standard DVD software.

Apparently people are getting some very good results.

I wouldn’t encode to SD from a DV codec, wastes information, at least I’d convert to DV50

Very good thread, one of the best for years, thanks fellows.

I have had brilliant DVD’s from the EX1 but, I have to say, the best were from material shot in the SP mode (HDV)! I then upscaled through Convergent Design’s box to HD and edited in Media 100. That application does a really good downscale and then the DVD is encoded with BitVice (VBR ave. 7.5, formatted in Studio Pro and burnt in Toast. I am sure that BitVice does a far better job in encoding than does Compressor.

Lately, now I’m shooting in the HQ mode, I have experienced all the edge twitter described in the thread. Obviously the camera is too good! I propose now to experiment with the detail turned down to -20 as suggested and hope for improved DVD quality. I have compared the BitVice downscale with that in Media 100 and the latter is visibly superior.

Hi Michael,

It has been hugely beneficial. I have been searching forums for the answers for many days and not found my answer, until this thread.

I will try shooting in SP mode and see what results I get from that, but I have to say, the results look pretty good from Steve’s workflow. Maybe a little bit blurred on low light shots, but then again, that could be my shooting.

For information, when I turned the detail off, I experienced no twitter/aliasing at all. Although I am going to test the camera again tomorrow by burning a variation of shots, SP, HQ, Progressive/Interlaced with varying degrees of detail and see what results I get.
