avi quality loss
I was trying to search posts that answered this question.
I know you should only render a mpeg2 file once because of picture quality loss. How many time can you re-render a avi file without losing any quality? thanks for your help. -

There’s no definitive number of times – it can depend on many things, including of course the quality of the original footage.
If all you do is render a DV file to the same DV format, there should be no loss, as you are just copying data. Once you add effects, titles, colour correction etc, though, rendering involves the use of a DV codec. The Sony DV codec is extremely good quality, and there were reports of up to 50 generations of rendering before significant degradation was noticeable, and it compared very favourably with the MS codec. I’ve never tried doing this many, but suffice it to say that whilst you remain in the avi realm you should have no problems with quality.

Isn’t the Sony codec in V4 & 5 the mainconcept DV codec?
Thats one of the cleanest DV codecs of all time with Canopus.
Gary if you have room and render uncompressed you can do it
as much as you like. -

No. It’s the Sony DV codec.
