[REQ] Intermadiate files codecs & presets

[MarcoRavich]

Hi there,
it would be extremely useful to support both PRORES-codec output and more advanced presets for intermediate files.

Let's start from the mighty @harrypm's ProRes The Definitive FFmpeg Guide, where explaing ProRes HQ StaxRip De-intelacing and shares a lot of ProRes HQ Encoding (Interlaced) profiles.

It would be also interesting to "port" Voukoder' x26* settings by @iAvoe (OneColumnEncoder author):

• Good x264 settings;
• Good x265 Settings

Other interesting resources:

• @rhutsAMD's / @antonkesy's FFmpeg command line samples from Recommended FFmpeg Encoder Settings;
• @jploaiza's comprehensive FFmpeg reference library focused on maximum perceptual quality encoding and advanced cinematographic post-production;
• interesting best x264 settings for NLE-oriented sources discussion @ Doom9;
• Data rate for shooters and editors article @ ProVideo Coalition

Last but not least, consider JSON profiles as implemented in @emilemassie's Massie VFX Open Media Encoder.

Thanks in advance.
