Hey.. I know that there are a lot of questions here regarding codecs and I searched before posting, but couldn't find what I'm looking for. I have 3 simple questions.
1) I have a Canon 5D Mark II. I film in 1080p resolution. I would like to send an unedited clip, straight from the camera, but from what I found out, Canon 5D's codec is H264. Is that correct?
2) The clip is around 110mb and when I export it using After Effects or Premiere Pro, with Motion JPEG A codec, it comes out at around 350mb. Using DVCPro HD 1080p30 only comes out audio (no video) at around 260mb. And I couldn't find HDV codec on either programs. Do I use Motion JPEG A at that large size or is there another option?
3) I'm a Mac user. Is there any software or app to convert movies to iStocks acceptance with ease? If so, which ones (preferably free.. lol)
Thanks a lot! I'm not new to video but I'm only really trying to understand it now. I hope this helps other iStock users too.
Thanks a lot,
Dan

    Posted Tue Feb 26 5:16PM | Thanks for the tip funky-data. I'll download it right away. About the Photo/Motion JPEG. I though Photo JPEG was for non-interlaced footage (such as computer animation, time-lapses that use photos, etc..) and Motion JPEG for straight-from-the-camera-footage. Is that correct or am I completely confused?  |
    Posted Tue Feb 26 5:34PM | Well, you may be right. My camera shoots progressive H264 and I convert it to PhotoJPEG and upload it. I think I am confused too
But don't worry, there are plenty of video guys with lots of experience, they should engage in the discussion as well.. |
    Posted Tue Feb 26 5:38PM | I just did a bit more research and I think I got it. I shoot at 1080p 30fps, which would mean it's progressive, therefore, not interlace, so I should infact use PhotoJPEG, right?  |
     Posted Tue Feb 26 6:00PM | The Canon 5D mk II shoots progressive, so PhotoJPEG at 95-98%. The files are going to be bigger, maybe a lot bigger, that's normal.
Since you said you had After Effects or Premiere Pro, you should use one of those. I use After Effects to convert all my clips. After Effects makes it easy to color correct and make any other adjustment I want to the clip and then export it to PhotoJPEG. |

Thanks Forrestbro. I found this topic here very useful too: http://www.istockphoto.com/forum_messages.php?threadid=188891
One thing is for sure. My 1mb (100kb/s download and 30kb/s upload rate) internet won't do much good. I better upgrade to at least 10mb!

Earlier versions were made before Canon's very high bitrate H.264 DSLR footage became well accepted for video aquisition, so those versions tend to crash or chop through footage. But CS5.5 was a big leap forward in this respect.
CS6 was a step backwards from an iStock videographer's perspective because it removed the PhotoJPEG MOV export option.
You can expect files to be very big. iStock is a bit behind the times in accepting only PhotoJPEG or MotionJPEG files in an MOV container... but they chose this format because it's virtually guaranteed to be compatible with any client's computer, no matter how old. |

I use Prem Pro CS6 and export to Photojpeg .mov no problem
