Telestream is an excellent company and you may want to ask this question in their forums as well.
Avoid AIC, it is a relatively old technology that has no place in newer video applications.
I'm not aware of any issues with Mainconcept H.264 files in Premiere, so that would be my first choice.
The H.264 files should be an accurate representation (quality) of the streamed video. If they are not, that would be a Wirecast issue, possibly caused by under powered computer or slow hard drive storage especially considering your doing two simultaneous HD encodes.
If you experience image degradation using the H.264 files in Premiere you should consider transcoding to Apple ProRes (LT). The files are bigger than H.264 but you will see no degradation. You can always delete the transcoded files when completely done and save the H.264 as archive originals.
thanks for the reply. I've never used premiere pro so i wanted to check that importing a h264 file and then doing some simple edits and exporting a h264 wouldn't cause any quality loss? I'm not looking to change the resoltuion or aspect ratio just split the files and then export the same files
the only output i have is a HDMI out on the MBP so i was thinking of using the external monitor output in wirecast to send the stream to a hyperdeck shuttle so i have a top quality recording inculding all the graphics and video conference shots in one uncompressed file, or a compressed but good quality h264 file.
Would that work?
In theory recording to the Hyperdeck Shuttle should work. My one concern would be sending a non-standard video signal to a recorder that may only accept ultra-stable broadcast standard video. I see the Shuttle accepts 720p60 and 1080PfS30 (as opposed to 59.94 and 29.97 respectively) but I could not say if the MBP supplies a stable enough signal at those specs. That would be a question for Blackmagic.
