DVD from Timeline

[Bernie Huth]

Hi,

I usually Export by Reference from Media 100 HD. Then I either use BitVice or Apple’s Compressor. I prefer BitVice, but I recently had a highly saturated logo that didn’t compress well, and found that Compressor did a good job. BitVice has a “Studio RGB” setting that expands the 16-235 range of Media 100’s codec to 0-255.

Hi,

Thanks for previous advice. I’ve got to the stage now where I’m testing Builds form DVDSP but whenever I do the resulting video is all jerky, whenever there is movement on screen (eg a hand wave or legs walking) they almost look as though they are strobing.

I’ve tried exporting by reference files and using export to quicktime using M100’s video compressor. Each time I compress these files using Compressor they produce this fault. If I dump the QT file straight into DVDSP there is no strobing but I need to change the colour settings (hence using Compressor).

Are there settings in DVDSP that i’m missing? I’ve gone through about 20 blank dvds now triyng to get this right!

Thanks

Alex.

Hi. This sounds like a field dominance problem. Compressor allows you to change the field order – try reversing it and see if that makes a difference.

[Alex Bond]

I thought that too but it doesn’t seem to be making any difference – I’ve tried it on Upper, Lower and Auto with the same results. I’ll try again but do you think there’s anything else it could be?

Have you read the Media 100 explanation regarding DVDSP here? It is not updated to the newest version of DVDSP, but the part about the cropping is still valid for NTSC.

[Kieran Matthew]

Are you working in PAL or NTSC ? When I first started to make DVDs I made a batch that looked fine on the computer monitor, but when played on anything “video” looked jerky etc. Turns out the compressor was working in NTSC and I was feeding it PAL (different frame rates etc).

[Alex Bond]

I’ve just checked – it’s all Pal (which is correct, I’m working in Pal). The source QT files are PAL and Compressor is working in PAL too.

Any more ideas?

[Alex Bond]

I’m using PAL, will the Dominance settings be the same?

Had no problems with compressor on the same machine as M100 or one without so I don’t understand why that piece suggests deleting the M100 Codec Component but anyway.

Perhaps if I try Bit-Vice…

[Kieran Matthew]

you’ve probably checked this (as part of above) but you’ve got DVDSP’s disc format set for PAL too ?

Also as a test can you try encoding a piece of draft media and seeing if that’s still jerky (just to rule out a field issue cropping up after encoding)
