Formats for noobs
Re,
A very basic question (I am sorry), something I don’t understand well yet.
My rushes files are in Quicktime H.265 L5.0, 30fps in 4K.
I just exported this (content based) footage in Apple ProRes 422 HQ, which gives a 2,01 GB file whereas I get a 236 MB file with the file exported in Quicktime H265 (100Kb/s*).
I guess theses 3 questions are actually the same formulated different :
Is there actually more information in the Apple ProRes file than in the Quicktime H265 file, and if there aren’t any, is the Quicktime H265 the best export I can get from this footage ?
Isn’t my Quicktime H265 export logically containing all the info present in the original footage, as the wrapper does not change ?
Is there an export codec that actually extracts more information from this container, like ProRes, which would justify the so increased size of the file ?
Finally, would you prefer MP4 or QUICKTIME or ProRes for an instagram reel ?
Thank you for your patience
Jean
* I never know how many Kb/s to choose for any project exports… is there any recommanded Kb/s-wise target for 4K H265 footage ?

Hey Jean,
As you point out, the Quicktime .mov (and .mp4) is just a wrapper. It has little influence on the actual quality of the video inside the wrapper.
The difference in the file size is to with one, the H265, is a highly compressed codec with Long-Gop (Timecode only ever so often), where the ProRes QT comes with less compression and every frame has its own timecode.
Yes, you can turn up the MBps on the compressed format and included more detail (less compression).
Depending on where the video will be shown, you might want to increase quality (have less compression).
But most importantly, start with the end in mind – where will your video be shown, and what technology is used for playback. depending on the answer to that, you should be able to work out what format to deliver your video in.
