PHOTO_JPEG via compressor workflow, from PRO RES HDV
A client has asked me to send him my HDV clips from my Sony V1U as photo Jpeg.
I am capturing the media with PRO RES at 24PA, and exporting from FCP via compressor with a custom setting for photo Jpeg that I made for 24PA footage.The file size is quadrupling! Am I doing something wrong?
What are the advantages of Photo Jpeg, and why would he want that format versus the format I captured the footage with? (I asked him this, and he stated that his clients want photo jpeg)Thanks for your help in advance!

How’d you set up the PhotoJPEG? I believe, PhotoJPEG @ 75% is 4:2:2, at 100% it’s 4:4:4. That could account for the bloated file size with no gain in quality.

aha! that would make sense for the huge file sizes.
I can’t seem to change the Jpeg settings in compressor, even if I make it custom. I can change the video quality, but not the actual compression setting like you can in Photoshop.
Can you make a custom setting for Photo jpeg at 75?
While we are on the subject, what is this codec good for?
Thanks Jeremy,

Yes. In the Encoder tab click the settings button for video. Choose PhotoJPEG for compression then slide the quality to High (which equals 75%).

Sorry, forgot to add the PhotoJPEG is a pretty decent codec with relatively small file sizes and nice quality. Also, it scales to 4:4:4 which is handy if you are in to that sort of thing. Apple never implemented it to its rt engine. Don’t know why.

The other advantage of the codec is that it’s cross-platform and comes standard with Quicktime, so it’s a decent choice when you are passing files from one system to another and you don’t want to deal with supplying the codec on the other end.
