love the perspective thanks for putting these vids out there!
As an owner of a c100 mark ii i would definitely recommend the c300. The c100 mark ii has great bang for your buck but for serious handheld shooting it can be a bit of a drag (the og c100 is even worse). The 1080 60p on the mark ii is a nice to have but i rarely use it especially for verite doc work. Ergonomically the c300 is much more flexible orienting the screen is super nice for stripped down handheld. Its also WAY easier and cheaper to build a solid shoulder rig for the c300. I hate HDMI cables they get knocked out all the time when you're moving around, being locked in to HDMI for any monitoring or recording is a total bummer on the c100. I think the c300 internal codec grades a bit nicer than the c100 mark ii though the prores image you can get with a recorder out of a c100 is solid. Go with the c300 and just rent things like a recorder when you really need em.
Hey liam, I assume you are referring to the audio compression between mp4 and AVCHD? I won't ever claim to be a sound guy but from what I understand LPCM with avchd is uncompressed audio and the mp4 audio is encoded with aac compression. Could I tell a difference in a sound test? probably not but uncompressed sounds good to me so thats what the editor gets!
AVCHD at 24 mbps LPCM is going to give you uncompressed audio which .mp4 wont be able to do. So if you're recording audio to the camera without a second system thats probably your best bet. I haven't exactly tested this but I recall reading that the AVCHD image quality is ~slightly better than Mp4. Though I would have a hard time seeing the difference in real world scenarios. Your issue is almost definitely the result of not using data import utility to offload the SD card causing the long clips to duplicate in the transcode.
FWIW I only ever use Mp4 if I want the internal slomo. Once you've start using Data Import you're just going to have to decide if the audio benefits of AVCHD outweigh the slightly more simple workflow of Mp4 for your uses.
How are you offloading the cards? are you simply dragging and dropping the folder or using something like data import utility to unpack the avchd folder from the sd card? It sounds like you are just dragging and dropping which can cause some programs (especially adobe) to duplicate very long clips, hence the reason you're seeing absurdly long transcode times.
As a c100 Mk II owner I've got to say I couldn't be happier with the camera. It's a workhorse plain and simple. I've used it for web commercials, weddings, documentaries etc. Payed for itself within a couple of months, and I feel safe knowing it will actually hold value fairly well. Love the black magic cameras but they just aren't as flexible. I haven't had a single shoot where 4k was necessary, and it's pretty easy to rent a camera for the rare occasions I do need slomo over 60 fps. As for fs-7 /a7s vs Canon I've got to say the sony colors have always unpleasant to me. My only real complaints about the EOS line is that they're a pain to properly rig out for shoulder use and being limited to 8 bit color is lame.
