PAL tape conversion to NTSC
Hello,
Recently I got a Kramer sp11d videoprocessor. I been working to digitalized PAL tapes for a while. I have some demand for NTSC DVD. I know the conversion is not a transparent proccess...so I would like to know if it's obvious to you to know which path is the right one. What would be the best approach? Software or Hardware. Right now I can play the PAL tape and convert them to directly NTSC on the fly with the kramer. Or should just use original captured PAL avi and transcode it with adobe media encoder. If the answer is not obvious...I may have to test both approach. Thanks |
Many folks use the QTGMC AviSynth scripts to perform the conversion with very good results.
http://www.designstudioschool.com/pe...n-t144363.html Above is an example, modify it to fit your workflow. Most NTSC players will play PAL discs without a problem, so the conversion may not be needed. All software based players handle it as well. Of course if you have an unlimited budget, a Snell and Wilcox Alchemist standards converter will do it in real time in the best possible quality. |

Did some quick test with adobe media encoder CS6. My PAL video include some static overlay text and some moving text. Once converted, static text of NTSC video look ok, moving text looks good too. But at the end of his action (when the moving text stop), it look fuzzy (not as sharp as the static text). Welcome to the magical world of conversion :D |
Interesting. I'll have to try this.

I want to test it first, before recommending it. I have alternate methods that are fine as well. This may not be an improvement, and simply makes the process take longer.
Code:

DGDecode seems to do the best job on MPEG-2 source files. I've had problems with other import methods.

Did you test it?:question: What about Snell and Wilcox Mach 1 "lower" budjet?:hmm: |
The Mach 1 seem to have NR filters but according to the diagram in the linked PDF it look like only
available for the SDI input-ouput:question: I may be wrong in my reading of the diagram:screwy: Anyone on this? Mach 1 PDF |
