Is SAME AS SOURCE the highest quality export?
I need to compress a movie for DVD and web and the editor’s project is in DV25 format – I was told Same as Source would be the highest quality because Animation, None and others are actually compressed in some way even though the file size is larger.
Does anyone have some advice to give? Usually i use same as source on the adrenaline in projects that are higher res than DV25 so I am curious if this still holds true for projects that are only DV25.
I need help asap if there are any kind souls out there.
thank you

Nope.
None has no compression. (it sez so in the name)
Animation is actually overkill. At 75% quality it is good for video sources.
If you do a ‘same as source’ export, you have in theory exact the same as your original.
BUT, the DV codec sucks for colored graphics, so it is better to choose another codec for your renders.If you do so, you get a lot of other problems. DV is lower field first, most other codecs are upper field first.
You end up with a mixed field dominance file, and without de-interlacing, this sucks.
Now, if you are in NTSC DV, you have other problems.
NTSC DV has 4:1:1 color sampling, where MpegII for DVD uses 4:2:0
Some DV decks can upsample/interpolate quite well, thus ingesting the material with a good deck at a better codec than DV can result in way better DV -> DVD conversion.Experiment, try, use your eyes. Do not let datarates fool you, this is just a very small part of the entire process / quality.
A well lit / shot / corrected DV shot can look better than a digibeta source. It all depends on the people / workflow.Bouke
