Rendering woes
on Nov 2, 2008 at 3:26:55 pm

Ok, so I know that when you add clips to a sequence the sequence settings need to match the clip settings otherwise you will have to render every clip before you can do anything with it. The problem I'm faced with is a client has provided me with .wmv files that are 30 FPS and 320 x 240. That's easy enough to match, the problem I'm running into is I have no idea what compressor these things are using, and as a result can't match it up in FCP. I'm using Studio 1 so I can't just have the program adjust the sequence for me. Am I doomed to render every clip? (AE and Premiere won't even recognize the files).

Not really. WMV is a Web delivery codec, not a an editing codec. So you have to transcode WMV to a QT file at, which should most likely be DV. Since WMV is not a codec which comes for free with FCP, you will need to purchase and install Flip4Mac Studio to be able import and transcode it. http://www.flip4mac.com/wmv_studio.htm

I can get it to import to FCP, and it will render and play in real-time. But I was afraid I was going to have to transcode everything (it was worth asking about though ^_^).

Thanks so much for the reply!

Nick

Ok, so I used MPEG Stream Clip to convert the files and make them usable by FCP. But now I can't get FCP to read anything that isn't the standard 720 x 480, DV/DVC Pro 29.97. I matched the sequence and the clip to these specs (720 x 480, 30 FPS, DV/DVC Pro square pixels. Audio plays, but it has to render the video. I'm out of ideas.

Those don't match. 29.97 is not 30. If your sequence is truly set to 30fps, it will have to render all the 29.97 clips.

I made them both 30 FPS since that's what the client gave me, but I also tried having them both set to 29.97. It works if I render it out to the full 720 x 480 but then it's blowing the image up by over 100%. Granted the final deliverables are going to be 320 x 240, but I'm not certain if this is screwing with the quality too much.

I made both the clip and sequence match these specs. 320 x 240, 30 FPS, square pixels, 4:3 aspect using the DV/DVC Pro compressor. What's interesting is that when I put this clip into a standard DV sequence it will play in real time with the green render bar, but it's all red in the one that matches it spec for spec.

I watched your tutorial on the subject today (great stuff). Would you recommend blowing it up and using it that way to make it work since this is getting shrunk down again anyway?

Thank you for taking the time to help!

If you know that you will end up 320x240 try to keep in tat size. Convert from WMV to QT, then blow-up and downsize is not little degrading workflow.
You may try converting the WMV to PhotoJPEG 75% instead of DV. You will extract better quality picture (422 YUV) than with the DV/DVCPro from the WMV clips, and (in theory) you should have more RT performance with this codec.

Thanks everyone for your help! I'm going to try the Photo JPEG as soon as I finish his splash animation. I just got word that my sources were supposed to be 640 x 480 so I'm going to see what the deal is before I get in too much deeper.

Thanks again!

Nick
