Editing Mpegs from a DVD

stannmaple · Post by **stannmaple** » Mon Aug 21, 2006 12:27 pm

I would like to first get files off of a DVD (which I learned how to do from this forum- thanks) and then edit the MPEGs. Is it going to be a problem to edit the MPEGs? I've read on here that they ARE editable and it is a good idea to turn smart render off, but I've also read that people much prefer editing AVI and DV files. What is the difference as far as editing? What problems may I run into when editing MPEGs? Thanks

Whilst you CAN edit MPEG files you must bear in mind that many users experience audio/video synch issues. From my experience these issues are mostly aggravated when inserting transitions between clips.

Thanks for the response. Since I'm starting with MPEG-2 though (from DVD) would it help if I converted it to AVI to edit and then back to MPEG to go back on DVD or would that ultimately end up losing a lot of quality? Thanks again for the help.

Hi Dann,

You're mixing different things in your message.
MPEG files ARE editable, yes, and most people prefer using AVI files than MPEG for editing. And some say to avoid Smart render.
Separately you're right on all three.

B U T : if you have MPEG to start with, as in your case, by all means do use smart render to avoid recoding untouched parts.
Don't certainly go back to AVI, use AVI if you can FROM THE START.
You have MPEG now, go with MPEG, just make sure you usi the same properties in the whole chain from editiing to authoring (field order, data rate).

Daniel

This is my opinion. Your mileage may vary.
No warranty implied. Not a scientifically proven fact.
Some may disagree. Use at your own risk.
Don't let children play with it. I never said that.

Stannmaple,
It would be counterproductive, to say the least, to transcode DVD-compliant mpeg2 to DV, edit DV, and transcode back to Mpeg2 to burn on DVD because each transcoding will reduce picture quality, not to mention wasting your time and increasing your chances of an operational mistake.

Your best workflow is to edit the mpeg2, using virtual cutting tools such as the scissors and Multi-Trim Video and Smart-Render the output video file. Then burn the DVD after setting the BURN properties to match the video file properties.

Mpeg2 is very editable. Mpeg does not cause audio/video sync problems. Your foot will not fall off if you edit mpeg2.

None, I edit my Sony DCR-DVD405 DVD camcorder MPEG-2 clips in VideoStudio 10 Plus without any problems.

Don't let John fool you. Your foot will fall off if you edit and add transitions to MPEG2 files. But, you'll like it that way.
