Q: Exporting FCE project to Apple Pro Res 422 HQ Quicktime conversion file

Hi Folks,

 

I have recently tried exporting an FCE project (HD 1080 16:9) as:

 

1. Quicktime file

2. Quicktime conversion using Apple Pro Res 422 HQ

 

and noticed that the Pro Res file is 2Gb. larger than the standard Quicktime file.

 

Does this mean the quality is 2Gb better? (it certainly looks crisp and clear)

 

Should I be doing this everytime I export from now on?

 

Any information much appreciated.  Regards.

A:

Transcoding your material from one codec to a higher quality codec will not improve the quality of your source material. You are always limited by the quality of the image prior to the transcode.

 

If you have a pair of shoes you want to store, you can put them is a shoe box, or you can put them in a shipping crate - but neither method will improve the shoes.

The shipping crate will just take up more space.

 

The only possible advantage of transcoding your AIC sequence from FCE to ProRes would be:

1) you force the need to repeatedly decompress and recompress the file  - ProRes will bear this better than AIC

or

2) you plan to use the file in an edit system that supports working directly in Pro Res.
