Q: Great problem on interlaced footage

Hi all,

I've just started to shoot 1080/50i footage (AVCHD) with a compact camera (Sony HX20V).

My final target is bluray.

I've transcoded with Compressor the original .MTS to Apple ProRes 422 LT.

Edited (in FCP 7.0.3) with some basic cuts and cross dissolve a bunch of test clips transcoded as above.

Produced the bluray with the "share" function.

The result, seen on a 42" plasma TV is awful: a lot of terrible combing and artifacts on any moving object/subject.

 

My "fixing" strategy will be:

- "sanitize" the system, erasing Perian and the Panasonic AVCHD importer

- verify the Compressor settings for ProRes 422 LT: here i need for your help !!!

- give a try to ClipWrap to transcode .mts->Prores

 

Any other idea?

 

Thanks a lot in advance

    Finalise your edit with all the trimmings (disolves, effects, etc) Do all renders required and export video with the current settings option. Convert to H264 or whatever format you use for blue ray at full quality within Compressor and make syre that size is the same as source video (i pressume 1920X1080 50i). Alternatively you can import the FCP output video to your authoring software and take it from there.

     

    Btw, what do you use to author your BR disc?

    For this try i've used the "share" function within FCP (obviously choosing Bluray from the dropdown menu) that produces a very basic menu in a ready to burn bluray structure (BDMV and CERTIFICATE folders).

     

    I've just discovered that is the Compressor transcoded footage (ProRes 422 LT) that has the problem.

    At the following link a stop frame that obviously emphasize the problem but that gives the idea

    So i need for a guide for the right setting to put in Compressor to make the transcoding in ProRes.

    Thanks again

    Lets take it from the top. If your source fottage looks like the picture you posted that the settings were off by much. If you can tell me the size of your source video then I can post some screen shots

    Ok here it is regardless of whatever Prores flavor you use:

     

    1) These are the video/sound settings: Leave as is

     

    1.jpg

     

    2. Frame controls. They should be off so that they take their cues from the source files.

     

    2.jpg

     

    3. Video adjustments leave untouched/ with all buttons unchecked

     

    Screen Shot 2012-06-27 at 18.06.28.jpg

     

    4. The size tab. Make sure that it is set to a 100% of source

     

    4.jpg

     

    5. Target tab. Leave as is

    Check your original settings before you set out converting your source material from scratch. If those match the ones above then it is most likely that the problem lies in your sequence settings in fcp. The sequence settings should be something like this:

    Please keep us posted.

    Is there any reason why you didn't use log and transfer to import and convert your MTS files?

    I think the AVCHD importer is good for viewing your MTS files but could be unreliable using it for anything else.

    @ hyphen

     

    All settings are exactly the same that you indicated also the sequence setting in FCP are identical

     

    @ David

     

    I'm not sure if i catched your advice: you suggest to use or NOT use Log and Transfer ?

     

    Thanks

    Is the field dominance in both your sequence and clip format set to upper? Additionally when you play your prores clips in quick time (and not within FCP) how do they look?

    Yes is the same, and the problem is present also playing the clip with QT.

    Made a test with log and transfer but the problem is still there.

     

    I've made also a "final" verification.

    A friend of mine did a ProRes 422 LT conversion on the SAME .MTS clip produced by my camera:

    the problem was NOT present also watching the clip on my system.

    Then it is my HW/SW setup that have a bug.

    I paste here below what i think are relevant infos about my system (it is in italian but i think is pretty clear).

    I kindly ask you if you see something "suspect" or if you need some other info.

    Thanks again to all.
