AVCHD to QuickTime file (Field Order)

Specific to Premiere Elements Version 12.

AVCHD to QuickTime file (Field Order)

Postby Di Hansen » Mon Apr 28, 2014 10:31 am

Working with AVCHD video input, saving to HQ QuickTime file. Do I need to select Progressive in the Field Order Option in Advanced?

Yesterday, I left the Field Order at its default setting (Lower, if I remember correctly) and my file exhibited interlacing-like symptoms (striations). Please advise. Thanks!

If this is an MOV file, sometimes Premiere Elements has trouble identifying the specs of MOVs and you have to help it find its way.

Do you know the specs of the video, Di? Is is 1920x1080p60?

Check the properties of your AVCHD footage. It sounds like your source AVCHD is interlaced. Interlaced AVCHD field order is upper field first. Check your footage and project properties to ensure that they match. Also check the properties that you have set for output. Quicktime is a container format and can contain many different codecs. What codec did you select for your output mov file? Is the field order for that upper field first or lower field first. If your field order doesn't match somewhere, the combing you get from interlaced footage will be exaggerated.

If the field orders match everywhere and combing is still objectionable, you can try outputting to progressive. Alternately, you can also set the clips field options on the timeline to Always Deinterlace.

Footage is shot 30fps, progressive* (Recorded as 60i)
Codec: HD 1080i 29.97, H.264
Field order: Upper First

I just saved the file again - same codec, upper first at 100% quality (instead of 90%) and the quality is much improved. I need to set the fundamentals of this file conversion in my head. I question it every time I perform this operation! Knowing they need to match will be my guideline + any other suggestions you make.

I'm not sure video can be both 60i and 30p, Di. It's got to be one or the other. They're kind of mutually exclusive. Likewise 30 fps progressive doesn't have a field order -- because it's not interlaced.

That said, what are your Project Settings, as listed under the Edit menu?

Until you get the video specs and the project settings in alignment, your output is always going to be a bit of a compromise, no matter what output settings you select.

If you open your MOV in G Spot or Media Info, what does it show for its frame rate?

Re: 60i vs 30fps
I follow what you are stating re: interlaced vs. progressive. The manual from my Canon Vixia HFG10 is messing with my head. I have my video camera set to PF30. Read the description including the asterisk. What does this mean? See attached file.

Ah, so that's 30p -- or, in shorthand, a 1080p30 file.

Start up a new Premiere Elements project then and, on the New Project panel, click Settings and selecting the project preset for DSRL/1080p30. That should match your video specs -- and whatever you Publish & Share from it should look terrific (or the best possible)!

Thank you so much! I appreciate your help!
