Hello everybody,

I am a little confused about the behavior in the export dialogue.

I select export a movie to the files app.
As a bit rate I have selected quality (30 Mbs) for H.264.
When I know want to have H.265 the quality setting remains the same with 30 Mbs.

It’s long time ago since I last wanted an H.265 export but I remember there where different bit rates between the two codecs for a certain setting.
Because this way the file sizes are identical and honestly I don’t see a big difference.

Maybe somebody has some insights.

Orci

I try to avoid worrying about this sort of stuff (in other words I know nothing) but yes I would have thought H265 should have a smaller file size than H264 at the same bit rate because the coding is more efficient for each frame regardless of bit rate.

Are the exported file sizes actually the same or is that just the 'estimated' file size?

The actual size is the same.
File info on iPad says it’s a different Codec avc1 vs hvc1.

Thanks for the info

If I get chance in the morning I will load up a file from my drone and try 2 exports and report back
