Apple Prores Codec (not 422) – Where is it?

[Rafael Amador]

Hi Elijah,
Codecs are the same for SD or HD. Only the size changes.
All the ProRess flavors are 4.2.2 and 10b.
Cheers,

Thanks Rafael,

For some reason (user error) when I exported my DV Sequence to ProRes the other day and it upsized it to HD. I just went to export it again and the resolution was a bit higher than DV, I cancelled and reset the timeline arrow and when I went to the settings dialog it was DV.

Dunno what I was doing but I think I determined what was “causing” the problem. Me.

Cheers Rafael!

Using ProRes has nothing to do with the format you exported. It’s a codec that works with SD or HD or anything else. You have to specify the frame size and frame rate when you export.

All the best,

Tom

Right.
A rule to fallow when setting the size for a custom movie is to keep the pixels macro-blocks that the compressed codecs need.
All the compressed codecs that I know use different macro-blocks sizes. MPG-2 use 16 x16, while DV use 6 x 4 pixels. H264 can use different macro-block sizes, being the smaller 4 x 4 pixels.
That means that sizes like 400 x 225 should be avoided because some full lines can not be integrated in any macro-block. However I don’t know if this would have much effect in the picture.
What I have no idea is the block structure used by ProRess. DVCPro HD I guess is DV like.
