Compression for Video Library Advice

[elijah stanfield] “-H.264 is nice, but too lossy
-MPEG2(.m2v) looks even better, but what’s the likelihood of compatibility issues?
-Blackmagic .avi is really good too, but will there be compatibility issues? “

H.264 is much less lossy than MPEG-2 at the same datarates.

MPEG-2 will be compatible with ‘everything’ for years to come but you’ll need twice the amount of spece for the same quality over H.264.

Forget about Blackmagic.

Have you thought of using PhotoJPEG? It’s better than anything you have mentioned (at over 75% quality) and can be converted to what ever then ‘next guy’ needs with ease.

Thanks for the response.
When I overlay the different compressed videos in premiere over top of the original and switch between them, the H.264 seems to be compressing more than the .m2V.
I would be interested in trying the JPEG, but all I can find is the Blackmagic motion JPEG and it comes out as an .avi. What’s the best way to export as a JPEG?

Most likely I will go with the H.264.

[elijah stanfield] “When I overlay the different compressed videos in premiere over top of the original and switch between them, the H.264 seems to be compressing more than the .m2V.”

Are you using exactly the same datarates for both the M2V and the H.264?

[elijah stanfield] “I would be interested in trying the JPEG, but all I can find is the Blackmagic motion JPEG and it comes out as an .avi. What’s the best way to export as a JPEG?”

You need to choose a Quicktime exporter and from there choose the PhotoJPEG codec – Sorry I don’t use Premiere so I cant give you the exact workflow.

I would advise against using either H.264 or M2V for content that is going to used for futher editing. Both are designed as delivery only codecs, unless you go for either very high bitrate (above 15Mb/s) or i-frame only output.

YES!!!! THANK YOU. Quicktime’s Motion JPEG B is perfect. It’s big but not even close to uncompressed and is looks just as good as the original footage.
Just to make sure. This will be viewable for most people if they have a regular old Quicktime payer?

MotionJPEG is not PhotoJPEG, the quality and file sizes are quite different.

even better!…the quality seems comparable, file size is about 20% smaller and faster render too. This is great. thank you.
