Premiere and format/codex!

Apr 8, 2013 9:25 AM

Tags: #formats #codex

I have been a photographer (amateur) for many years, and with the possibility to use my DLSR to produce HD-video my interest for video has increased significantly.

 

In the world of photography formats are not that many and the RAW format has simplified editing. But... the world of video seems to be much more complicated  and complex. Not only are there formats there is also codex.

 

I have tried to grasp all the information in the subject that is available on internet. I'm more confused after all this reading than I was before. There are many contradictory 'Holy Grail' -truths out there.

 

We know that it's a good idea to save jpg files in tiff format while working with a picture to avoid artefacts and when the job is done the picture could then be saved back in jpg.

 

In the world of digital video there is a similarity to jpg in the form of codex. I understand that many means that encoding to a intermediate codex (less compressed) makes the editing more efficient.  With editing I mean colour correction and grading. The purpose of encoding is to get rid of information that we don't need to perceive the clip and to make the file smaller with the help of algorithms. Is it then really possible to obtain a better 'raw' material for editing to decode it to a less compressed codex?

 

I understand that Premiere import most every format and codex to the timeline. Is Premiere only saving changes to a separate file and just leave the original footage until it is time for export? Would it be beneficial to import a less compressed codex in Premiere or SpeedGrade.

 

My main purpose is to save my videos to a server and show the videos on a HDTV (1920x1080) . What format/codex would you suggest? The material could be avi, mpeg or mov.

 

I hope you get the core of my questions. Not having English as native language is a ***** as it tends to be too many word. Please bear with me.

    PR is a non-destructive editor, meaning that is will not modify your original footage and it edits in the native format. Whatever you do during editing, is saved in separate files and the original is not touched in any way, other than reading to get the info. There is usually no need to use intermediate codecs, unless you have a very underpowered computer or a non-supported codec.

     

    Even when exporting, your original material is not modified in any way, it just creates new material, based on the original material. The best codec for your purpose would be H.264.

    As Harm said, most of the time you don't need transcoding so as to do your job in PrPro.

    There is a firm conviction based on legacy workflow that if you shoot in compressed format, you need to transcode for better quality. Although that may still be valid for some other editing applications, when it comes to Adobe Suite - it's a huge misconception. See e.g. this discussion. See also this The Video Road blogpost on colour processing (read up to the end so as to understand how it is applicable to PrPro).

    On a side note, the English word is codec, the plural is codecs with an s.  Codex, with an x at the end, is something entirely different.

    >DVD that I would like to convert into some suitable format to store on my server and show them on a HDTV.

     

    The 1st question would be... what codec does your server use to stream video to a TV?

     

    Or... what codec will your TV play for streamed video?

     

    Once you know those requirements, you can choose a codec

     

    But... do be aware... that a DVD is MUCH lower resolution than BluRay, as would be used for an HDTV, so you will need to also verify that your HDTV will "upscale" a DVD quality file

    Jstramn, the clip was shown here in Sweden some time ago and it is really clever. For those that do not know they speak Norwegian in the clip, which we in Sweden do understand as well as Danish (just for information ).

     

    While we are at it we can probably agree that the most spoken language in the world is bad English.

     

    I knew it was Norwegian, but only because of the NRK logo. To us 'americans' it sort of sounds like they are speaking some ancient dialect, which actually works really well for that particular skit.

     

    I agree bad english is most common, even amongst native speakers of it.

     

    Back to topic: It looks like youe questions was answered well enough by Harm, with bonus info from others. Correct?

    I have a couple of DVD that I would like to convert into some suitable format to store on my server and show them on a HDTV. Any suggestion what software to choose and to what format.

     

    I use this:
