Re: [Avid-L2] Sony A7 camera recording formats?

 

You've received good replies, but my two cents. It's really simple these days.


Almost all camera codecs are MP4 based. MP4 is a fantastic codec. If you are on modern hardware, or you are shooting "cinema quality" you don't need to consider anything else. 

Modern NLE's and hardware handle MP4 long-GOP well. Most "current" hardware has MP4 acceleration. Avid was, indeed, slow to the party, but you should not have a problem on modern hardware, Mac or PC.

Choose the highest bitrate available in a format your NLE will handle natively. In my opinion, 100Mbps is the lowest acceptable long-GOP bitrate for full 1080p "broadcast quality" work. 

Opinion:
 
I always edit native. Hear me, Avid? Always. Life is too short for intermediates.

Always "10-bit" when possible. 8-bit sucks. Always has. Always will. 

Always progressive at 29.97 (if your hardware is limited) or 59.94 if you've got the horsepower.

Cheers,

Specifically, codecs write frames to files in the order they will be needed during decode. If there is a B frame the codec already has the needed I or P frames.

 

Quality is equal on all frames blowing another myth. That's why every IPB frame also has a frame of error correction data.

 

Moreover, for a given data rate limit Long GOP provides higher quality.

 

AVC-I does solve the problem of not cutting on a GOP boundary. It also needs higher data rates – try 4K at 422 onto an SD card. The only reason to transcode is because most NLE companies will not use NVIDIA GPU cards to do the decode. They try to get away with a CPU and multiple threads. Many buyers don't even know an i5 doesn't support multiple threads aren't and CPUs are not getting faster: i7700 vs i6700. (Also not more than 12 threads are supported so 6-cores are enough—but check multi-core performance.)

 

Simply select the highest bit rate codec. If AMA doesn't support it. That might be a hint—because h.265 is coming along fast for 6K and 8K cameras.

[Avid-L2] New export Error

 

Doing a Send To Playback here, got a new error I've never seen and can't get rid of.

Error exporting metadata!
AEffect::ConvertKFListToParameters - UserParameterKFData -failed to convert key frame data to parameter.

As far as I know, we aren't dealing with any after effects keyframes or multi layer graphics that would cause that type of an error.  lots of stills and purchased video, but it should all be dnx145.  don't want to do a mixdown as i'd like to be able to disect this in future generations.

Thanks

try this:

Fast re-wrap, no transcode, Avid will eat the files afterwards.

I'm told our series will be shooting standups with a Sony A7.  From checking the specs I see the recording formats are:
  • AVCHD: MPEG-4 AVC/H.264
  • MP4: MPEG-4 AVC/H.264
  • XAVC S: MPEG-4 AVC/H.264
The camera person suggested mpeg 4 when we told him XAVC S doesn't play nice with Avid.  He then mentioned AVC I.  I take that to mean AVC- Intra.  I assume that would be the AVCHD: MPEG-4 AVC/H.264.  My gut tells me the AVCHD format would be the best choice but my gut isn't a savvy cameraperson.  Anybody got a suggestion for recording format.  These are standups so it's not going to be a lot of material so file size doesn't matter. 

Seems to me the choice is between MP4 or AVCHD.  Both seem to be MPEG-4 AVC/H.264 so what is the difference?  Is AVCHD an Intra frame Codec and the other long GOP?

Re: [Avid-L2] Sony A7 camera recording formats?

 

You touch on what confuses me a bit.  Both the MP4 and AVCHD in the Record formats are listed as H.264.  My head always poo poos H.264 for things but clearly it's not truely the case given the AVCHD is also H.264.

Re: [Avid-L2] Sony A7 camera recording formats?

 

I think I'm having deja vu all over again.  We have requested a test clip but time will tell if we get one.  At least I know XAVC S is a  problem but I was able to use Adobe Media Encoder on a show we did to get it into Avid but who needs the hassle?
