Are you changing the Compressor setting of the timeline in FCP, or are you going to Quicktime conversion and choosing H.264 compression? If you're changing your timeline Compressor, that's wrong. Keep that at ProRes422.</p> <p>Second, don't even use Quicktime Conversion. Export a Master by going to File &gt; Export &gt; Quicktime Movie. Make sure you're exporting at Current Settings and the Make Movie Self-Contained option is check marked. Then bring your Master into Compressor to create your H.264 and MPEG files. Compressor will do a better job.</p> <p>Also, you didn't explain your H.264 settings...</p> http://www.videomaker.com/community/forums/topic/codec-and-compression-confusion#post-74075 Wed, 18 Jan 2012 14:01:17 +0000 Ian James Smith 74075@http://www.videomaker.com/community/forums/ <p> Mark,</p> <p>             I take my m2ts clips, archive them 'as-shot', then make a conversion to the PAL equivalent of your format (720 x 576) in mpg2 of good quality. I am not familiar with the procedure to be followed in Apple's 'Final Cut', because I do not use it. A great deal depends upon the quality of 'codecs', (I use 'Main Concept') and what settings you employ. For example I have reduced my GOP's to twelve, from the default fifteen. Taken overall, that sometimes gives your clips an 'edge', because of the increased density of the all-important 'I-frames'. Within mpg2, itself, I tweak everything up close to the upper-limits permitted by the DVD-Standard. That makes for somewhat larger files and longer processing-times, but pays dividends in the quality of the finished product. My philosophy is that having my footage, for editing, available as good-quality mpg2 saves a lot of hassles and permits a very direct route to disc. But, some purists might not agree with that, with (say) my bit-rate of 9200, for example, as standard. There is another school of thought which regards hoisting the rate above 7000, as a waste-of-time, just the same as there are those who say that you cannot 'improve' on 'ffmpeg' as a codec. What I do know, is that I am quite happy with the comparatively minor amount of the original m2ts image-quality which has to be sacrificed on the way to DVD. None of this addresses your problem, directly, but some of it may be helpful.</p> <p>Ian Smith</p> <p>Dunedin, New Zealand.</p> <p> </p> http://www.videomaker.com/community/forums/topic/codec-and-compression-confusion#post-74073 Wed, 18 Jan 2012 13:20:31 +0000 Mark 74073@http://www.videomaker.com/community/forums/ <p>I take my ,mts files and throw them into Toast converting them to Apple ProRes 422, to edit into Final Cut Pro 7. I will edit my piece, then using Quicktime conversion in FCP, I set the output to usually h.264, and the size sometimes to 720x480, 16:9 since I seldom need pure HD, and export it to my external hard drive.

Then export a self-contained Quicktime of your timeline. (File &gt; Export &gt; Quicktime Movie. Make sure the drop-down menu is set to Current Settings)</p> <p>Bring that exported file into Compressor and apply the TRANSPORT Stream MPEG-2.</p> <p>Changing the Rate Conversion to Better or Best will not do anything unless you're actually doing a frame rate conversion.</p> <p>Not sure why you want to de-interlace either. De-interlacing doesn't increase quality. The reason why it may have looked better is interlaced material doesn't look too great on a computer monitor, so de-interlacing may have led you to believe you did something good when you viewed your MPEG file on your computer. Is there a reason you're trying to de-interlace?</p> <p>Also, keep in mind that the station is looking at your file on broadcast monitors, which is what you should be looking at as well. It's not doing you any good judging your image quality while looking at a computer screen.</p> <p>Increasing the bit rate should result in better quality, but check with the station you are delivering to and make sure they don't have a limit. They really should have provided you with specifications. Also, do not change the GOP. It should be left at IBBP, Closed.</p> <p>Also, since you're converting HD to SD, go into the Frame Controls pane, turn on Frame Controls, and change the Resize filter to Best.</p> <p> </p> <p> </p> http://www.videomaker.com/community/forums/topic/television-compression#post-64194 Tue, 14 Dec 2010 06:28:18 +0000 Josh Tiedt 64194@http://www.videomaker.com/community/forums/ <p>Shoot in HD and to be honest, I think I have this project with the wrong sequence settings.  Usually, I'm in ProRes 422.  Oops.  I used Program Stream MPEG-2 setting in Compressor and at first used the default settings.  Junkie.

That's not very common in my opinion though. The reason you want a deck is because you can wear out the heads if you have a tape based camera. A deck is more robust.
