Hi Gord
I contacted their support and asked what their preferred settings were (they are very helpful by the way) and here are the ones they sent:
We recommend using Flix Pro8.5 with VP6 Codec
Recommended settings:
– Key Frame Settings: Max 60 Key frames
– Encoding Mode: 2 pass
– Rate control VBR
– Max bitrate ~400-500
and the size they recommend is:
640×360 or 720 x 405 if 16:9
The bitrate of course depends on how much action is in the sequence (talking heads means lower bitrates) I think mine were around the 550 mark.
With these settings you will bypass their automatic encoding procedure after uploading and gives you more control over quality.
Hope this helps
