Looking for codec troubleshooting help
We have several systems. A couple are still on PS 10.8.5 with PT 10.3.10.
Some are Sierra OS with PT 12 HD (I believe one is 12.4, and the other is 12.5). There are a few systems at various points of inbetween. Point being, the issue is occuring across different OS and PT versions. We receive videos from our clients in various codecs. ProRes, H264, DnX, etc. We generally have the least amount of problems with the DnX. But occasionally, we have ProRes and h264 videos that work on some systems and not others. Generally, when they don't work, we get the missing codec error from PT. These videos will open on MPEG streamclip or Quicktime on the same system, but pro tools just doesn't like them. Take the same video to another system (sometimes even 2 systems that are the same OS/PT version) and it works fine. Take a different video that is the same codec, and it works fine on a system that has problems with other videos that tare the same codec. Take a pro res and convert it to h264, and it works. I have run all of the codec installers and updates for them. It really seems to have no rhyme or reason as to why some videos work on some systems and not others. Anyone run into anything similar? Or have any insight as to why this is happening? |

Re: Looking for codec troubleshooting help
I find that it's usually a double issue- it has to work for that version of PT, AND it has work for that video hardware. For PT10 and PT12 compatibility, ProRes Proxy is pretty good. And as I've mentioned elsewhere on this list, Adobe Media Encoder is a detailed and very fast way to remux videos. Make a preset that works on all systems, and use that as a global ingest. Once you use AME, you'll never use Quicktime again...

Re: Looking for codec troubleshooting help
I can't speak to all the codecs, but I do know that H.264 can have varying results, and Avid even says so in one of the knowledge base articles on using videos in Pro Tools. What was recommended to me by some here, and what I've started doing, is to convert anything I get to DNxHD, which seems to work best. To make the conversion I use the Brorsoft Video Converter. But there are others out there as well. All I can tell you is that since I started doing that, I've not had any issues running videos in PT when I'm working on a score.
Why there are issues...I have no idea. Others here are way more knowledgeable than I on that front!

Re: Looking for codec troubleshooting help
MP4 and AVCHD are both h264 variants. The problem with h264 is the compression that's used, intra-frame coding (Google is your friend here) and that some sources such as phones use a variable frame rate. Playing back h264 is processor intensive taking resources away from the CPU or GPU. Also it causes problems when working to picture, especially in PT, and it's a real pain to try and sync fx etc. When using h264 I do a DNxHD 36 working copy. Never had a problem with one of those.
