When I am done with the edit and ready to output, I generally select h.264 but sometimes I use Mpeg 4. When I output my video looks a little pixelated and not near as sharp as others that use h.264. I might be overlooking a setting when I export, hence the question here in the forum.</p> <p>Thanks</p> <p>Mark</p> <p> </p> <p> </p> http://www.videomaker.com/community/forums/topic/how-best-to-convert-avi-into-quicktime-dv-or-mov#post-37381 Thu, 12 Jun 2008 11:20:56 +0000 waywardmuse 37381@http://www.videomaker.com/community/forums/ <p> I just licensed some wildlife footage to an educational production company.  The footage was shot with a Canon ZR200 camcorder and captured via firewire into.avi.  They want the raw uncompressed footage so they can edit it themselves.  But they don't like .avi.  I am not willing to release the original tape and cannot duplicate it so they said Quicktime format on CD or DVD would do.  How do I do this in Premiere Elements 2 with as little compression as possible?  When I choose to export to Quicktime, the multiple codecs to choose from under the advance tab and all the possible setting variables confuse me.  Someone said I would need to download Quicktime Pro to do this properly.  Is this true?  Why wouldn't a free shareware converter like Apex work just as well?   What is the best way to do this?   Can someone suggest an optimal setting in Premiere 2?  Computer is desktop Sony dual processor.  OS = Windows XP Media Center edition.  Thanks, Judy</p> http://www.videomaker.com/community/forums/topic/compression-issue-red-blockiness-pixelation#post-71564 Wed, 12 Oct 2011 10:01:37 +0000 George 71564@http://www.videomaker.com/community/forums/ <p>I'm having trouble compressing a video (NTSC, .dv format) without getting blockiness in the red area.  The .dv file does not have it, but when compressing for playback on a Brightsign player, every file I make has this blockiness.  I've tried H.264, and both HD and SD MPEG-2 Transport Streams.

So I need to pick a good intermediary codec that is very compatible with most systems, maintains high quality, and balances a file size that isn't too out of control. </p> <p>Source of footage: Canon XH-A1 HDV. I will be exporting to 1920x1080 60i resolution, and here are my ideas/options as I see them: </p> <p>1) Photo-JPEG Quicktime files. Seems to be compatible with almost all systems and maintains high quality, but the file sizes can get large. Also, deciding what quality level to use (I currently go with 95%/best) is tough. What is optimal for HDV? </p> <p>2) H.264 Quicktime files. Thoughts? Seems to be a great codec for maintaining quality and smaller file size than Photo-JPEG, but how universally compatible is it? </p> <p>3) Something different than the two above that I haven't thought of. Please let me know your thoughts!</p> <p> Thanks, Joel</p> http://www.videomaker.com/community/forums/topic/best-compression-software#post-51129 Wed, 30 Sep 2009 09:54:46 +0000 henrybenj 51129@http://www.videomaker.com/community/forums/ <p>I have a movie shot in HD 1 hr and 18min...1.18gb and the client needs it compressed for their website. I used FCE and export to quicktime using low quality internet broadband. Tried the same in iMovie 9 as the client wants files under 10mb<br /> Any better compression ideas?</p> http://www.videomaker.com/community/forums/topic/mpeg-2-compression-problem#post-47580 Fri, 05 Jun 2009 16:51:20 +0000 mad_styles 47580@http://www.videomaker.com/community/forums/ <p>&lt;p style="padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 10px;"&gt;Hi, I was wondering if someone could please give me some advice on MPEG encoding in Premiere Pro CS3. I'm using the standard MPEG 2 DVD when exporting my movie (which is made up of PNGs 1024 x 576), the problem is its just compressing my movie way too much. <br />Even when I shrink down a single PNG image to 720 by 405 they still don't look as bad as when converted to MPEG format. Even when I export it to MOV from Aftereffects its still not as compressed, but i need to keep the MPEG format for a DVD. <br />My movie is only 1 min 40 sec,roughly 50mb I've got 2 other things to go on the DVD which come to about 800mb all up, so I've still got 3.9gb unused which I'd rather use to maximise the resolution of my movie. <br />I could increase bit rate but apparently most DVD players can't handle higher than 9, surely there must be some way i can get better picture quality? <br />&lt;!-- End of post content --&gt; </p> http://www.videomaker.com/community/forums/topic/newbie-editing-and-compression-question#post-47041 Thu, 21 May 2009 06:21:15 +0000 cnil1 47041@http://www.videomaker.com/community/forums/ <p>I am struggling with understanding compression. I am of the understanding that ideally one would shoot in a minimally compressed file format and then upload into software such as Corel VideoStudio X2 at which time edits, transitions and subtitles are added. Then the compressed version would be saved for actual use. Based on my needs, I'll likely use H.264 which I understand is the same thing as AVCHD. With this scenario, the compression only occurs as the last step.</p> <p>However, the camera I am looking at, a Panasonic AG-HMC70u, records in AVCHD, and I don't understand what happens when I import into VideoStudio and edit. Are there potential problems editing and subtitling video that is already compressed with AVCHD by the camera? When I export the "final version" will that version be "double compressed" - once by the camera and again by the software?</p> <p>Many thanks to anyone who can help explain this to me!</p> http://www.videomaker.com/community/forums/topic/video-compression-im-not-getting-something#post-46637 Sun, 10 May 2009 12:24:56 +0000 amereservant 46637@http://www.videomaker.com/community/forums/ <p>Hey everyone,</p> <p>I came here because I've spent endless hours researching this topic and so far have had no luck.  I've done numerous tests and so far the best I've came up with so far is pretty much the MainConcept AVC/ACC (MP4) Codec, 640 x 360, CBR @ 1,200Kbps for HD video streaming.  I've played with the On2 Flix Pro, QuickTime Pro (mine doesn't have the H.264 option available for some reason), and recently messed with ProCoder 3.  I've encoded the same video using all of them and the ProCoder 3 seems to be slightly better using the H.264 codec, but I'm still not satisfied.  WMV 9 codec in Sony Vegas has by far exceeded all of them, but it's not near as flexible of a format as the flash formats.  </p> <p>What I'm trying to figure out or achieve is video quality like that of Facebook's video.  I'm astounded by the quality of my HD videos when I upload them and Facebook converts them.  </p> <p>Can someone give me some really good and helpful tips for achieving much higher quality video, which codec ranks highest (I'm using Sony Vegas), and what is the best method for a target of around 800Kbps - 1200Kbps datarate streaming video.</p> <p>Whoever solves this riddle for me I will forever be in debt to.  It's hard to believe it's so difficult finding any sort of compression guides online that is targeted for streaming video from one's own web server.</p> <p>Thanks in advance!</p> http://www.videomaker.com/community/forums/topic/hdd-vs-dv-is-quality-compromised#post-46242 Mon, 27 Apr 2009 14:12:25 +0000 HighKalibur 46242@http://www.videomaker.com/community/forums/ <p> </p> <p>&lt;span style="font-size: 7.5pt; color: black; font-family: Verdana;"&gt;Hi, I know little about the technical aspects of cameras. I plan on spending a nice chunk of savings on a one- or three-chip video camera. I love the convenience of direct-to-hard drive storage. However, I have never been able to get a definite answer as to whether or not I am losing picture quality by not recording it to a DV Tape. Is this the case?&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;</p> <p>&lt;span style="font-size: 7.5pt; color: black; font-family: Verdana;"&gt;What is the difference in quality when recording on a HDD or DV tape? Is there one? &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;</p> <p>&lt;span style="font-size: 7.5pt; color: black; font-family: Verdana;"&gt;Also, as far as filmmaking goes, can anyone suggest a great starter camera (until now I have used camcorders) for an independent filmmaker that produces good picture without unnecessary luxury accessories. In other words I’m looking for a great ‘deal’ camera. &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;</p> <p> </p>
