1080-60i so why is is 30fps after importing?

The whole interlaced vs progressive thing is confusing. I have a HF100 1080-60i camcorder (also records 720-30p, though not sure it is true 30p or not). When I import into iMovie as a 1080i file, its shows 1080i-30 in the finder and the .MOV clips also show 30fps. Why not 60i? Is iMovie converting the 1080-60i to 1080-30i? I know iMovie can't do 1080p. Would it be better to create a 720-30p iMovie instead? Looking for the smoothest quality output, which is why I shoot in 60i rather than 30p. Thanks.

No, don't record in 30p.
In 30p each "field" (..as Matt has explained; a "field" is half the information that's contained in a single frame..) is more-or-less doubled, or recorded twice. When that reaches iMovie, iMovie plays the video at twice the normal speed! ..because it thinks that there should be two separate or different "fields" in every frame, not the same field twice.
Record at 60i. That's the "traditional" way to record video. That's compatible with iMovie. 30p is NOT compatible with iMovie.
Using a p ("progressive") frame rate is intended to simulate film, and to be a cheap way - at 24p - to shoot video and then have it transferred to film for showing in cinemas.
Avoid anything with p on the end; always shoot at an i frame rate, because that's what iMovie understands.

Why are my AVCHD clips recorded in 60i being converted to 29.97i after import?

Hello, after importing footage that was recorded in 60i on an AVCHD still camera, the clips are converted to 29.97i.
How do I maintain their original format during import?
Thanks.

It is a misunderstanding, your video has not been converted.

Why are files larger after importing? idvd 08.

why when i import a 2.38gb file does it say 4.92gb and its too large for project? any answers are greatly appreciated. thank you.

Material on a DVD must be in a standard format, and video's format is mpeg-2. It sounds like you must have a video in a very compressed format and so iDVD has to uncompress it and change formats (transcoding).
Really though, what matters is length. iDVD can fit up to 1 hour of material at highest resolution (best performance setting in preferences) and up to 2 hrs maximum (best quality setting). Or you can use the Pro setting, and it will take a bit longer to encode/burn, but the quality should be similar to Best Performance.

Why duel bit rates after importation?

I imported my shared music folder. It shows duel titles & bit rates for SOME songs. (128 & 160)
Should I keep both, or, rid myself of one or the other?

If you have duplicates, I would keep those at the
higher bit rate. There won't be much in it between
128 kbps and 160 kbps but the 160s will be of a
slightly higher quality. It's really up to yourself
but there is no reason to keep both as you are just
using up disc space with duplicates
Thank you!
My thoughts exactly. Needed an expert opinion. Thanks again

Why no 1080 60i in Encore?

ok, I'm just wondering why no 1080 60i in encore?
it seems like it's a supported blu ray format, so I guess I'm looking for another mastering program.
can anyone help shed some light on this for me?
thank!
-Josh

Aha! Jeff... thank you! ok, so the 1080i60 is the 1920x1080 @ 29.97 (and the i is referring to the 60 fields from 30 frames).
well... duh.
ok, that just seems odd, but I'm down. I thought 1080i60 was an interlaced 60frame format, like most video is interlaced 29.97
why the heck do they refer to it as i60 when it's just the same as ntsc's interlaced 29.97?

Trouble Importing Canon XF Files at 1080 60i (59.94i)?

I am completely new with Premiere Pro and editing in HD for that matter. I am still using the trial version of Premiere Pro CS5.5. My issue is that I shoot on an Canon XF300 at 1080 60i. When selecting a new project I select the following Preset [Canon XF MPEG2 1080i30 (60i)]. This is the only Preset setting I see that is 1080i and at 60i?
My issue is that I can view my XF files in the Media Browser and their properties read 59.94i, however when I import them into PP CS5.5 their properties then read 29.97 fps.
I shoot fast moving objects that require the 60i setting - how can I import these Canon XF 1080 60i (59.94i) clips into a project/sequence with the same 59.94i setting? I have looked at the manual and additional published articles and thought my issue was due to me using the Trial version, however in CS5.5 it is supposed to have all codec support so I think I ruled that out.
Any help will be much appreciated!!!
Thanks!
Chris

Thanks Jim for the response - so I am using the correct setting after-all. Apparently I do not understand the difference between frame rate and field rate.... it has been a truely monumental learning curve shooting with this camera and now this editing software. I am having fun with the stunning footage but it has been frustrating at times.
One additional question - why does the Media Browser list the "Frame Rate" of these clips as 59.94i and in the Project folder the "frame rate" is 29.97 fps? - Is it because the 29.97 FPS is literally 30 frames displayed per second and the 59.94i is the interlaced 60 frames to make the 30 fps? Obviously you can probably tell I am a novice.
I should then expect that this playback of this "60i" footage on my computer display will not look as smooth as the playback through a blu-ray on a HD TV?
Thanks again and I appreciate the help!

How to get better resolution on Blu-ray (1080/60i)

I'm experimenting with my new AG-AC160A camcorder and have been shooting youth hockey games in AVCHD mode, 1080/60i, 1/120 shutter, manual gain and white balance set appropriately, and florescent scene file setting due to lighting in rink. I have PP CS5 and am disappointed with the relative lack of HD-crispness when the Blu-ray output is played on my HD LED set. I used the above settings based on recommendations I saw in the forum somewhere. Any suggestions on what I can try differently? Thank you.

To elaborate on Ann's great advice, the Sequence preset you should be using is AVCHD 1080i30 (60i).
A good way to start out with the correct sequence is to import your clips and then drag one onto the "New Item" icon at lower right of Project Bin. This will create a new sequence to match the source material automatically. As Ann mentioned, you have a non-HD preview format, so if you rendered the timeline to green, and checked "Use Previews" on the final export, then your Blu-ray could have "SD quality" footage in it!!
Curious why the 1/120 shutter, hoping to get better action motion?
If you have a current timeline using the incorrect settings, go ahead and add a NEW Sequence with correct settings, open original sequence and "Select All" which is CRTL + A, then CTRL + C to Copy. Then go to the proper AVCHD sequence and Ctrl + V to Paste entire contents. You will now have the edited sequence moved into correct sequence settings. Now use Export and in AME choose "H.264 Blu-ray" and choose the 1080i preset and export, then use results in Encore. The Blu-ray should look excellent when done correctly.
When exporting from AME, do NOT check the box for "Use Previews", as you want to encode direct from original source and skip any intermediate render clips.

Accidentally Shot 1920 x 1080, 60i

Shot some footage today using two DSLR cameras. One was incorrectly set to 1920 x 1080 60i and when I imported into FCP, the video is not smooth. tried exporting it and got the same result. The other video was shot 24fps. I brought a 60i clip into the project window and exported it using H.264 but no luck. Not sure what to do here or what I have have done wrong. I suspect you may need more information and I would be glad to give it to you on request. I am a bit of an amatuer (obviously) and I may need someone to walk me through it. Any help would be greatly appreciated!
Thanks!

Hi Ian,
Thanks for the reply. I agree that something odd is happening here. FYI when I run the files through quiktime, they also do not run smoothly. In other words, I imported the files through FCP and after the clips didn't ruyn smoothly, I went to the Event Folder/Original Media and tried to play the clips that way (through Quicktime) and I got the same issue. Does that tell you anything? When I play the clips on the camera they play fine. Is there perhaps an import setting error?
I tired reset speed but it did not change things. Also, there was no place to reset the speed to 24p. I assume the project is set to 60i since I assumed FCP sets the project to the first clip that is dropped into the project.
Does any of this make sense to you?
Thanks

1080 30p recorded as 1080 60i ?? (Jeff B. or Ann) ?

Using CS6. I set my camera on 1080 30p, but the owner's manual shows this:
After further searching I found that the explanation seems to be that 1080 60i is the wrapper.
So, when I set P. Pro CS6 to 1080 30 p, P.Pro tells me that's the wrong setting and promps me to select this editing mode.
Upper field in progressive video ? No mention of progressive here.
When I export my project as progressive, using Encore, I can see small jaggies where contrasting colors meet. Very much like I used to see with interlaced video.
I tried Max render quality and 2x VBR encoding, but I still get the small jaggies.
Suggested solution?

Hey, I see the whole gang is here! Just thinking out loud but follow along. (Rounding to 30 for simplicity only). If you record in TRUE 30p, the camera is grabbing/recording an entire frame of video every 1/30 of a second. There are no fields, just one full frame (image) from one moment in time. When recording 60i, then two individual fields are recorded at different times, for instance all the even lines are grabbed at one moment (1/60 of a second) and the odd lines are then grabbed 1/60 of a second later. These fields are combined to create a frame of video covering 1/30 of a second in total. However, since the two fields have a temporal (time) difference, the two fields may not match where there is motion. Things changed in the scene between grabbing field 1 and field 2. That's where we get motion blur and artifacting with interlaced video, while a frame of Progressive video is a "snapshot" of ONE moment in time.
My understanding of the "30p in a 60i wrapper" is that the camera is still grabbing a full frame in 1/30 of a second, as it would if recording 30p, however that frame is then split into two fields before being saved to tape/ SD card. The two fields are from the same MOMENT, so no temporal difference, but they are not "identical" as one field has all the even lines and the other has all the odd lines to complete the frame. Each "field" contains unique information, though the times match on both. These two fields when combined into a full frame should have the same "look" as though it was recorded as 30p.
So the way this "30p in a 60i wrapper" thing ought to work is that when viewing it, the 60i should look the same as 30p, should it not? So edit AND deliver as 60i. If the video is "deinterlaced" at some point, you would be throwing away one field, in effect halving the resolution, which is going to make the video look jaggy.
I could be wrong, but this seems logical. Please correct me if I'm off base ;-)
EDIT: Of course, if exporting for web, then that output is always Progressive, so not sure how that gets handled. Would it help to "Modify > Interpret As > Progressive"?? I have no footage with which to experiment unfortunately, but I feel that for DVD or Blu-ray, then 60i seems the way to go.
Thanks

1080 30p or 1080 60i?

Hi everyone,
I am wondering which format is better in general (in quality):
1080 30p or 1080 60i.
I have a Canon Vixia HF20 and can't decide which mode to stick to (have done both and am not sure which one is best)...
thanks

I've been asking this also. To be more precise (hopefully without hijacking your question): These Canon cameras can shoot in 60i (the default) or 30p, and we wonder which is the better choice, assuming we will use the captured footage in iMovie 09.
Does the answer change if we are NOT using iMovie 09? I'd hate to send tapes to the archives that were shot at compromised quality just because of a quirky software issue that hopefully will disappear someday.
For straight camera to TV, I believe the default 60i is superior as it conveys more information when motion is present in the image. The TV deinterlaces as it is designed to for the best possible picture. Again, as I understand, the 30p option just writes two identical -instead of interlaced - fields to tape. (I'm not sure why this would lead to any better result in iMovie, which would toss every other interlaced field, giving the same net result.)

Reverse Telecine DVCProHD 1080/60i 24p Problems!

Heres what happened.
1. Captured DVCProHD 1080/60i footage shot in 24P.
2. Edited footage in 29.97 rate.
3. Realized Pulldown was never removed.
4. Selected the bin with all original media, and then selected "tools" menu and "Remove advanced pulldown"
5. FCP6 batch processed for a while. clip by clip.
6. after process was finished a few clips per bin are offline.
7. FCP will not "reconnect" these offline clips.
8. FCP will not import these clips when accessed through the finder (drag and drop to the bin).
What happened? I need to reimport these clips. I would appreciate any and all help.
Heres more info...
1. the clips that processed properly show 23.98 when getting "item properties>format"
2. offline clips open/play in Quicktime.
3. when importing offline clips, FCP gives incompatible/unsupported error.
4. in finder duplicating and renaming offline clip doesnt work.
5. exporting offline clip to another DVCProHD clip doesnt work.
thank you for reading.

Wish I could help, but can only post that I too am having problems with progressive footage.
Heres what happened for me.
1. Captured DVCProHD 1080/60P footage shot in 24P.
2. Edited footage in 59.94 rate.
3. Realized Pulldown was never removed.
4. Selected original media, and then selected "tools" menu and "Remove advanced pulldown"
5. Got error stating footage not DVCProHD (which it is).
6. Tried DVCPro frame rate converter > 23.98 (tried all variables)
7. At the end of processing clips I get the incompatible/unsupported error.
Did you try the frame rate converter? This option seems great with the ref video option.

After importing images from my card using LR 5.4, the GPS data does not show in the metadata panel. However, when I look at the imported images using Bridge, the GPS data is visible. Anybody know why LR is not seeing the GPS data? Camera is Canon 6D.

After importing images from my card using LR 5.4, the GPS data does not show in the metadata panel. However, when I look at the imported images using Bridge, the GPS data is visible. Anybody know why LR is not seeing the GPS data? Camera is Canon 6D.

Ok, the issue seem to be solved. The problem was this:
The many hundred files (raw and xmp per image) have been downloaded by ftp in no specific order. Means - a couple of files in the download queue - both raw and xmps. Most of the time, the small xmp files have been finished loading first and hence the "last change date" of these xmp files was OLDER than the "last change date" of the raw file - Lightroom then seem to ignore the existence of the xmp file and does not read it during import.(a minute is enough to run into the problem)
By simply using the ftp client in a way that all large raw files get downloaded first followed by the xmp files, we achieved that all "last changed dates" of the xmp files are NEWER than the related raw files. (at least not older)
And then LR is reading them and all metadata information has been set / read correctly.
So this is solved.

1080-60i so why is is 30fps after importing?
