I used to use Photojpeg codec in a .mov quicktime container and set quality slider to around 90% but it appears to have been discontinued, so I am needing a new workflow for exporting videos out of after effects for uploading.

I'm assuming for CGI that H264 is the next best alternative, so within media encoder which bitrate is preferable in order to keep the quality high enough for acceptance and also which should used VBR or CBR considering that the source footage is a rendered image sequence, also in Media Encoder the sliders go up to 50, is this overkill?

Are there any other settings in Media Encoder which should adjusted to maximize quality?

Thanks.

I use 50Mbps VBR for HD. I think the sliders go up to 250 if it's 4K content. I go with 100 though.

If it's CGI I assume you would be shooting 4k. If it's 50 MB/s then that is very adequate, if it's 50 Mb/s then that's rather poor.  1 Byte = 8 bits. I think Adobe uses bits so 50 isn't that good. If you've been using PJpeg then your used to large files. ProRes 422 would be a much better choice over 264.

I only work with full HD. Within Media Encoder both target and max sliders only go up to 50 Mb/s so I guess i'll have to play around with both codecs to see what works best.

Thanks.

If you change the 'level' of H.264 then they'll go higher.

For 4k footage with H264 I use CBR and 100 Mbps.
If you use HD 50mbs should be fine.
For a while I used ProRes, but I stopped because some of the agencies I work with do not accept it, especially for time lapses, as the files get too big
