[Brian Alexander] “1. Should I consider another I-Frame only format format for archiving or will I,P,B Frame format work for my usage? Any reasons NOT to use h.264 for archiving?”
Quicktime H.264 has a subtle gamma shift bug which you may not like.
[Brian Alexander] “2. I’m using Compressor and can’t find handles to encode my H.264 with a 4:2:2 color. In fact, I can’t find any detailed documentation on how quicktime encoding works with H.264. I can’t tell if my file is encoding with 4:2:2 or 4:2:0. I know that Episode gives you the handles to make this happen but I don’t have Episode yet. Any thoughts (besides “get episode”)? “
compressor (or rather Quicktime) does not support the H.264 Levels and Profiles required for 4:2:2 support
[Brian Alexander] “Since most of my material is destined for a progressive display this makes sense to me. Any suggestions? “
I’d capture at 720p
[Brian Alexander] “4. I’m trying to steer clear of hard drives sitting for extended periods so I’m just burning files to 25GB Blu-Ray discs for storage. Do you think Blu-Ray readers will be around for the next 10 years? (I think so, DVD data drives have been around quite a while.) “
Most certainly.
[Brian Alexander] “5. Am I way off the rocker here? Is there anything else that you would consider working with HD material that provides a direct-to-disk workflow?”
Probably 😉 – Have you considered Data tape?

May 18, 2009 at 6:47 pm in reply to: help – from nice to junk: m2t to mpeg-2 via Sorenson or Procoder to DVD via DVDitAny chance of post a before and after screen grab, just so we know what differences you are seeing?

MPEG-2 does not support a frame size of 848×480, the maximum horizontal dimension for SD material is 720
So, transcode to a frame size of 720×480 and set the output frame aspect ratio to 16:9. This is easy to do in compressor, Squeeze and cleaner
This will only play back as letterboxed on a 4:3 display but will fill the screen (just) on a 16:9 display.

You don’t state where you plan to have these clips finally end up, but I’d stay with DV and not worry about the black bars. All you are seeing is 704 source in a 720 frame.
If you plan to have these end up back on DVD then you won’t see the black bars, they’ll be in the overscan area:
https://en.wikipedia.org/wiki/Overscan#720_or_702_or_704.3FIf you plan to put these on the web or compress them down to a smaller size it’s a good idea to crop into the picture anyhow.

[Jan Nowak] “so the main question remains unanswered – is there a way to change the default 720×576 output size while using a DV codec? “
No. PAL DV is 720×576.
[Jan Nowak] “If not is there an other codec used for editing that allows full video size customization?”
Yes there are, what do you access to on your system and what are you actually trying to achieve?

It’s obviously a carboncider specific filter. Sadly the relative crop filter is a nightmare to use, I can’t use it.

If it’s not there then it’s not going to help you. Should I assume you are working with PAL source?
If you don’t want the black bars, you need to crop them out but this may result in a distorted picture, crop 8 from either side and 6 from top and bottom.

If Procoder is still the same as CarbonCoder, you need to set a filter on the source files called Video Source Properties and in that filter for a pixels aspect ratio change of 15:16.

[John Nelson] “OK, I am doing some testing on what video looks good using Compressor 2. I also downloaded Apple’s bitrate calculator. My question is this: Will I have to go through all the bitrates, from small to large in order to find the one that works best? Or is there a more efficient method that my small brain has yet to grasp? Sorry, that’s two questions. Thanks in advance, Joh”
Depends on what you have and where you want to deliver to.

Is your source 4:3 or 16:9, or either?
