File format (AVC HD – too heavy)

[Angelo Lorenzo]

AVCHD isn’t a compression format, it’s just a branded mix of camera/recording media/file folder structure/tuned codecs.

AVCHD is compressed using a high bitrate version of h.264 which makes it more suitable for editing than highly compressed web video which may be of the same compression scheme.

I would probably install the Avid Quicktime codecs https://avid.force.com/pkb/articles/en_US/download/Avid-QuickTime-Codecs-LE-2-3-8 and export to Avid DNxHD (available in Premiere/Media encoder as a Quicktime video codec) as an intermediate file. It’s performance is similar to Apple ProRes.

Unless you know what you’re doing, then setting mpeg2 encoding settings to be edit friendly can be a daunting task.

That sure is complicated… Do you know where can i learn some more about it? I’ve always been intrigued about the history of formats and how and why they were created. I make use of them but sometimes i don’t know why… If you can, please send me a link (or even text me) about it.

Yes… I understand, but it’s still too laggy on my computer. Avi and Mpeg2 are way better.

with this i would be creating a lighter copy of the AVCHD videos. Like Proxy editing? If that the case, wouldn’t it be better to save them to .Avi, edit and the replace footage? (sorry if i am not understanding what you meant and i’m just saying rubbish)

If i tell you the AVCHD properties would you be able to tell me what are the best mpeg2 properties to set in the export panel?

Thanks for the answer
