7D MKII - IPB-Lite Data Rate

peter-ops — Wed, 26 Nov 2014 16:24:08 GMT

Hello,

Does anybody know the actual maximum Data Rate for the new IPB-Lite option? I need the info for the Data Rate Calculator we use at work. I havent been able to get my hands on any footage as of yet, so the maximum Data Rate would give me a good place to start.

Even better, if anyone has some test material they would be willing to send me I would be really grateful.

Thanks a bunch folks

Hi Peter:

Are you enquiring about data rates for CF and/or SD cards for MP4? If so, CF cards must be 10MB/s or faster while SD cards 4MB/s or faster.

Hi Paul,

Thankyou for your response. I was enquiring about the actual compression applied to the .MP4s when the IPB-Lite setting is used to encode the file. Although I understand H264 is going to be a variable bit-rate, im curious to know what the maximum data rate would be. For example, I believe the ALL-I mode caps at 90Mbps. Im using this information to enter into a Data Rate Calculator so people can calculate the amount of data they have shot or will shoot using this compression.

If you could help that would be great, otherwise I thankyou for your response.

Regards

Pete
