AVI lossy??
I have some long videoclips that I only need a few seconds of video from. I see that reducing my editing project only eliminates the clips that aren't used at all - but doesn't shorten the clips I'm only using a small part of.
So if I put the sections of video I need in a timeline and then export as an avi file - and then use that as my new source, I could delete the original long clip. but will this degrade the original footage quality? or is it all "digital" and therefore non-lossy? thanks |
Re: AVI lossy??
AVI is a 'container' format. It's the compression scheme used for the data that is held within the container file that will make the difference.
If you are re-encoding then there will be some sort of loss in quality, but it really depends on the codec used. I know that PremierePro has the ability to export your DV clips back out without re-rendering the bits that haven't been changed with effects etc. Give it a go and let us know. Andrew |

Thanks - I used to know that! :)
I'll check out which codec I'm using and see... |
Re: AVI lossy??
While you're at it, let us know what editing app you are using. :-)

Ahh, yes. An excellent and fine choice, sir!

Robert..
If your sequence codec matches your source codec, and you haven't made any changes (except for in and out points), then you will loose no quality. So long as you have "recompress" unchecked in any export option.. Unfortunately, your title is a bit misleading..Unless you're capturing uncompressed 4:4:4 footage, everything is considered lossy.... |

Of course, you can check the results yourself.
Using your typical workflow, export a clip Import your clip, adjust the time line by a tad, export your clip repeat several times until you are on the nth generation Write your nth generation clip (and the original) to your output media (DVD RW+/- for example) Examine your results on an output device (your TV) |
