An update to my query – I reviewed the files again. It is now clear that when I play the file in fcp, it is fine. When I export it as a Quicktime movie, self contained, current settings, portions of the video are being dropped while the audio is being transferred as is. Any advice on how to rectify this problem will be appreciated. The compressor output only reflects the QT file which is flawed (to quote a colleague – you cannot make chicken soup out of chicken poop).

I need some help again – same project, different problem. I now have used fcp to create mov files of the 15 chapter (each one about 10-15 minutes long). They are in H264 and 1024X768 format (I hope those numbers are correct since editing is a second language for me 🙂 ). While the final product needs to go out to the “producer” as MPEG-2, I first have to get a peer review done. The requirements for the peer review are that the submissions must be in mpeg or avi. Since most folks do not have Quicktime Pro, I decided to send them in as MPEG4 which the free Quicktime download will play. If you need additional info, I will be happy to provide them. The fcp sequence prior to exporting to Quicktime shows the Keynote portions to be 1024 X 768 and the video portions to be 1440 X 1080.

The original mov files are fine. When I import them into compressor and export as MPEG4, the resolution is fine, but as soon as the endoscopy videos start playing (after a few keynote/QT slides), a portion of the video disappears (like a ripple delete with the audio track locked) and then the audio is out of sync with the remainder of the video and remaining slides. The missing video – about 10-20 seconds long never shows up again. Any suggestions on how to approach this problem will be appreciated. There are a couple of chapters without video clips and those are fine. Thanks!

Rafael: your method worked for one of the sequences. It did not work for the second sequence – I looked at the format in item properties and it has 3 different resolutions, including 1920 by 1080. In the conformed sequences, there is 1024X768 for the keynote and 1440Xxxx for the video. I have decided to redo/renarrate this sequence as that will be much faster.

Thanks!

Thanks for your wise and considered response. Your insight is very good. Reminds me of my dad – he was a physicist and if ever I asked him a physics related question, it would not be long before we got to the fact that I was lacking in my fundamentals. FCP, I am learning, is not my forte either! Fortunately, I am a physician now and not a physicist. I am enjoying the challange working on this project and hope to do more as the opportunities present themselves. The best way to learn is to try, learn from mistakes and move on – I am at this time somewhere between the “try” and “learn” phases.

Thanks!

Do you think that the match sequence response likely is the cause of the differences in the size of the picture?

Thank you. That is very instructive. I will tweak the files tonight and let you know how it worked.

Thanks!

Just read: https://forums.creativecow.net/thread/8/990091

That was very helpful. So I have learned that not all SD is created equal. SD from compressor is poor. There are other methods to create an SD DVD that give a far better product. My confusion stems from thinking that SD is SD, not matter how you get to it.

Thank you for your reply. I am happy with going straight to MPEG-2. The reason for checking out the quality of the SD output was that I know that the final product will be SD and wanted to see what the final product will look like. Based on your reply, it appears that this “SD” is not the same as the quality that will seen on an SD DVD prepared using an MPEG-2 file. I think I have some significant knowledge gaps here: why should the SD product put out via compressor have a different quality than creating a standard definition DVD from an MPEG-2 file?

Thanks again,
Sreeni

Thanks for the advice folks!

[Sreeni Jonnalagadda]

Thank you for your reply. I will look into FCS? Does the quality differ significantly though when comparing a workflow with Prores+FCP versus AIC+FCE?

Thanks again!
