Default work flow to export a 4K file from edius, to a Mpeg2 file

A Question:

Can you export a 4K file through HQX to a Mpeg 2 file, which will be then converted to a Mpeg 4 file through Handbrake.

Or is it just as easy to export to an AVi file, then into Handbrake to convert to Mpeg4.

I don't work in 4K, but the rule of thumb for any kind of encoding is that every encode step will cumulatively reduce the quality by introducing the compression artifacts inherent in the codec, which may make the next step look even worse.

So my advice is to minimize or eliminate the intermediate mpeg2 step. The newer versions of handbrake can take HQX if I'm not mistaken, allowing you to bypass the mpeg2 step. You can also try a straight MP4 from Edius, it has been improved in Edius 9, or if you have the tempgenc h264/avchd plugin, you can use that to use an x264 encoder similar to handbrake straight from Edius.

mpeg2 goes up to HD 1920x1080 only

what are you making with Handbrake? a 4k mp4 or a HD mp4?

Hi Anton,
At this stage I'm not using 4K professionally, as I don't think we need it with what I do. However what I'm trying to do is educate myself as to what to do when the time comes.

My work is almost totally 4-8 min to camera/interviews and sames size corporate product video for replay online, Facebook/Clients web pages etc. I have camera now able to shoot 4K, but always use 1980 x 1080 with stunning results.

As always thank you for your help.
Regards
Pete

in that case, edit the 4k footage in a HD project setting, this will allow you to reframe the 4k footage (be sure the HD project setting has lanczos3 HQ enabled)

then export to mpeg2 HD and use handbrake for the encode

Handbrake is really fast in encoding when the source is mpeg2 HD (encoding at 225 frames a sec on my PC, 9x realtime)

it is way slower if you geed it with HQX files
