Video quality awful after editing with iMovie

Hope someone can help.
When i edit gopro camera footage in iMovie the quality is awful after exporting finalized clips/footage.
If i play the clip imported directly from the camera it appears in crystal clear HD. As soon as i do anything with it it degrades to the point where it almost looks like a 'negative 'shot.
Any help greatly appreciated.

1. Ask on the iMovie forum, that's the best place for iMovie help.
2. When you get there, ask about export settings. Sounds like that's where the issue is.

How do I retain the original HD standards after editing with iMovie ?

Hello,
I have a camcorder that uses AVCHD. The image size is 1080 x 1440 and the audio codec is Dolby Digital at 448 kbps.
I can import these movies in to iMovie with no problem at all, likewise I can edit them and make a project.
However, when it come to sharing or publishing the project, the highest quality option I have is 'Apple TV' at a resolution of 960x540 with the sound being linear PCM stereo.
Is it possible to retain the original frame size of 1080 x 1440 with the original audio codec of Dolby Digital at 448 kbps ?

Well, being honest, I don't know that I need this. I was thinking that if I retain the original file size I would retain the quality.
I plan to store my finished project not on DVD but on my PS3 which has an external drive to hold my home movies.
When I view the original files in the 'raw' AVCHD format on the PS3 the image is ever so slightly better and I get to use the Dolby Digital soundtrack.
When I view my finished iMovie projects the frame size
(but not the picture) is reduced and this seems to be causing some very slight judder during panning shots. Also the soundtrack is just linear PCM.
I was theorising, that by retaining the original settings I would remove the slight judder and get to keep the digital soundtrack.
Is this the right approach ? or is something else causing these two issues ?

Deleting original video from ipad after editing in imovie

Hi everyone. I am new to imovie on the ipad and I have just bought a GoPro Hero 2 to take some video.
My problem is that the video I am taking is in large clips. The camera is on for about 20 mins at a time and the useful footage is about 5 - 45 sec long each clip. I am planning to make about a 5 min movie but as you appreciate the amount of footage I take to get 5 mins of the good stuff is huge.
I want to know if I can make a project of multiple clips, that I want, but delete the original video which is 98% rubbish and clogging up the ipad? This process is going to take some time so I just want to get what I want ready for editing and delete the excess.
I tried to delete the original footage from iphoto after I edited out the stuff I wanted but then the project footage was lost.
I apologize if this has been answered or if this is a basic question but as I said this is all new to me. Any help would be appeciated.
Thanks in advance.

I am trying to do video editing with iMovie 11 9.0.8 . I am running OS X Lion 10.7.5 I have no sound,any suggestions please.

This seems to have fixed the issue: on your desktop, hold down the [OPT] key and click on "Go" in the menu bar; holding down the [OPT] click on Library, find Preferences, and then delete all the files that start with "com.apple.itunes.XXXX.plist" where the "XXX" is whatever other things may exist - as long as they end in "plist". From my experience, preference files are rebuilt by the system after the next restart, so you have very little worry of losing any important data; the worst that could happen )and NOT in this instance, but for other plist files) is that you may have to reset the application "preferences" again when you next start it up, to act or appear in a "preferred" customized way for you.
Once you delete the .plist files, empty the Trash, and either log out or restart the computer. Once you're back up and operational, start iTunes and your iDevices should reappear in the sidebar (if that's open) and/or at the top of the screen (if that view is enabled).
Hope that helps. It definitely fixed my problem!

Can videos not recorded on the new ipad be edited with imovie?

can videos not recorded on the new ipad be edited with imovie?

Hi
Please rephrase Your Question - I'm not clever enough to get it
There are lot's of Cameras that record in lot's of different ways that can be edited in iMovie.
No iMovie can not use all Video-Codec's in the World - they are zillions and many needs to be converted to something iMovie can open and work with.
• Still digital Cameras as Nikons - Import into iPhoto and then in iMovie Event's window import from iPhoto-videos title
• miniDV tape Cameras - connects only via FireWire - then just Import from Camera into Event's
• SD-Card or Hard Disk Cameras Connects most ofthen via USB and Import from "File or other"
• from Internet - (out of my range - Guessing) - most will need to be converted into something iMovie likes - I would try
- StreamingDV .dv - or -
- AIC (Apple Intermediate Codec)
So as You see - I don't get it !
Yours Bengt W

Video Problem - Cannot "Edit with iMovie"

In Aperture 3, when I right-click a video and select "Edit with iMovie", iMovie starts up but my video file does not appear. iMovie just sits there.
I have tried switching the "Edit with" program under Preferences to Final Cut Express, and FCE is able to display and edit the video. Just not iMovie.
I am shooting with a Nikon D300s at 24 FPS, 1280x720, under AVI.
Does anyone else have this problem or know of a fix?

Like you the idea of using Aperture to manage my video appeals to me, in my case though it is not practical as I could not keep the amount of vision I shoot live on the system.
The workflow I would suggest for your video content would be.
Set up a location for the video to be stored, a fast drive is needed for video editing.
Set up Aperture so that it imports the video by reference and store it on the aforementioned drive.
Sort, review and rate your videos using aperture.
Create an album containing the vision you want to use in a program.
In your video editing application, click import, in the import dialogue box you should now be able to navigate to the media and movies area of the import dialogue box, select APerture and select the album you want to use for the edit.

HF10 and editing with iMovie '08

Hey guys, I've been looking at AVCHD camcorders for about a year, but I've been waiting on a flash based camcorder that has comparable to quality to HDV. Looks like that has finally arrived with the HF10. I have two questions. Do you anticipate many compatibility issues between the HF10 and iMovie '08? (If there are, do you think Apple would correct this via software update?)
Also, has anyone tried using the "High" video quality rather than "Full" in iMovie? If so, how does it look and how is it to work with? I doubt my computer (Macbook, 2 GHz and 2 GB of ram) would run smoothly using the full HD, and the high format would be more than sufficient for my purposes. I would like to use iMovie '08 for importing and organization, and iMovie HD for editing.
Thanks in advance for any replies.

Thanks for the prompt reply.
*>>Chroma-key are easy and standard here (three tools at least to do it with*)
You mean only FCut is the place to look for those effects?
I'll take a good look at the sites you pointed out.
Anything good about this outfit?

*HERE is another nagging one for you* (if I may) - not specific to iMoviexx, but possibly affecting downloads, upgrades to iMovie etc...
Concerns errors reported in Send/Rcv via WiFi on my MBP:
I get a lot of Send and Receive errors - as monitored by Network Utility.app when on my wireless network. Actually 10-20 after just 1/2 hour of WiFi activity. Going thru a Linksys WRT54GL router into a HughesNet satellite modem. AND, if I PING another device on my wireless network, I often get LOST PACKETS. All an indication that at least in my case - and I hear the same many Forums denizens complain about similar issues.
Now, as I download important stuff through the wireless network - say, the current many updates/upgrades for Mac OS X, iPhoto etc... and the MBP, do such occurrences render the downloads unreliable? I do not get any message of incomplete download or such as Install such wirelessly downloaded upgrades, but I am concerned about applying upgrades which would have been damaged by such xmission errors. OR, perhaps errors are flagged and "corrected" somehow??
Meanwhile, I have recently started to download -especially upgraged - via a direct LAN connection between my MBP and the satellite modem. However, seems to be a setback to me, especially since my most mundane among my Win machines have no trouble communicating over the wireless network.
Thanks again!

Sony AVCHD clips "judder" after editing with iMovie9

The video plays back smoothly on a TV screen in 720p when played directly from the Sony HDR-TG7VE camcorder, but after editing in iMovie the panned shots judder. The movie looks so bad it is hardly possible to watch it. The picture also becomes much "softer". My workflow is: importing as Large 960x540 file, exporting to AppleTV via iTunes as Large file with the same settings. I am recording the movies on HD HQ setting, which I guess means 720p as well. I would appreciate any help how to fix it.

I feel your pain. I own a the previous model, a TG3 and was pretty dismayed by the amount of "judder" i saw after it had been through iMovie. As you state, when viewed natively off camera, image is smooth as silk. If you google AVCHD and Judder you will see a lot of comments on this (half of them mine!).
As a general comment, a lot of people have said with some AVCHD cameras and panning, the golden rule is DON'T. If you have to, do it at extremely slow speeds.
I wasn't really happy with this, as i'm convinced it's happening somewhere in the import/export of iMovie.
Look at my example i posted up a few months ago, is that what you are seeing?:
http://gallery.me.com/cosconstantinou#100376
This weekend, someone off a different forum presented me with a glimmer of hope. He also owns a TG3 and has been using Elgatos Turbo Hd usb convertor thingymebob. Look at this link, scroll down to the comments (at 9:46pm) and download his clips from yousendit:
http://techmoan.wordpress.com/2009/03/26/elgato-turbo264-hd-hands-on-user-test-a nd-review/
Check out the 720p 60fps at 10,000kps clip, it's STUNNING. I was so relieved to see the difference.
Trouble is, I don't know how to recreate this in iMovie. It's (the above clips) been encoded by the Elgato stick and not been through iMovie. If I view them on my Mac and open movie inspector it says it's "H.264/AVC" by format.
If i try and recreate these settings as an export in iMovie ("export to Quicktime) I don't get the same smooth pan-could be something to do with the "AVC" element mentioned in format.
I also noticed my picture getting far softer after being imported into iMovie. I guess as the AVCHD is being converted into AIC, that was always going to happen. It's basically 2nd generation from the off (AVCHD is too compressed for iMovie to edit it natively). If you are ever thinking of editing a larger size file, 1080i, then consider this guide and follow it to the T:
http://blog.davidglover.org/2009/03/creating-hd-video-with-imovie-09.html
except at step 4c (tick "both fields") and at 5a change the resolution to “1920 x 1080 HD” and increase the bitrate to 16200=makes it 1080p instead of 1080i and actually looks the same on your tv as straight off the camera (almost). I am using a PS3 to watch my movies back, which is more capable than Apple TV i believe.
I'm sorry I cant be of more help. I have been hunting high and low for an answer to the judder issue and still haven't found anything concrete. Some blame the AVCHD format, some say its our CMOS rolling shutter, none can tell me why it doesn't happen straight off the camera, but does via iMovie (or other video editing programs apparently).
If you are recording in 720p, then you video is progressive, so it cant be an interlacing issue.
Best of luck with your search, keep me posted/update this thread if you find any answers and if you do nothing else, download the clips from the Techmoan link above and check out the one i mentioned. It's taken me 3 months of searching to find anything close to that as a possible solution.

HELP! iPhoto 08 Quality loss after edits

HELP! iPhoto 08 Quality loss after edit!
Any edited version, no matter how minor, causes the file size to be cut in half!
Original 3872 x 2592 is 3.1mb at 300dpi .
Edit version 3870x2590 becomes 1.5Mb at 72dpi.
B&W conversion 3872x2592 becomes 1.6mb at 72dpi.
Seems like a major degradation! iPhoto 6 wasn't this bad.
DPI change is not a problem but the file size change sure is!
PLEASE! any ideas before I upgrade all my files to 08. Please - don't say Aperture, it's still too slow and cumbersome. Trying to avoid Lightroom and stay within Apple sphere.

It really isn't a big degradation. There is a jpg compression when you make any edit but you might be hard pressed to see the reduction unless you're enlarging/printing the file to very large sizes. The most critical part of an image file is the number of pixels in it.
The reduction in size depends on the image content of the photos. If there's a lot of the same color, i.e. like lots of blue sky or a same color wall, that type of image will see much more compression than a very intricate photo. Also when removing the color information for a B/W conversion reduces the file size considerably. Do a Google search for jpeg compression and you'll find some very informative descriptions on how the compression is performed and what part image detail plays in the resulting file size.
You would have to compress the file a number of additional times time before you'd see the change. And with iPhoto's Revert to Original capability, you can start a new edit fresh with the untouched digital negative.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Why are frame sizes increasing after editing with Nik plug-ins?

I’m using the Nik Collection of plug-ins with Aperture, and have discovered that the frame size of the resulting edits always end up larger than the original - sometimes much larger.
The original image starts as 4592 x 3448 but after editing, the longest side of the resulting image is typically over 5000, 6000 or even 7000 pixels.
I recently worked on a cropped image that started at 4138 x 2759 and ended up at 7361 x 4908, after editing with a combination of Dfine, Viveza, Color Efex + Silver Efex. If I export a version during the editing process, and then carry out futher editing, the frame size increases again.
I’m exporting from Aperture using the TIFF - Original Size (16 bit) setting.
Can anyone tell me what’s going on here? I’m concerned that the quality of the images is being compromised by the enlargement.
I'm using the latest set of Nik plug-ins, with Aperture 3.2.4 on a MBP running 10.6.8

Keli
In order to open Aperture in 32-bit mode by default you can right-click on the application icon, select "Get Info" and check the box marked "Open In 32-bit Mode" (or you can continue to run it by default in 64-bit mode and just get forced to re-open the app anytime you need to use plug-ins that can only run in 32-bit mode).
hope this helps!

Horrible final video quality in After Effects CS6 when rendering a 1920x1080 video with H.264 format

I've been using After Effects CS6 on my Macbook Pro for over a year now with no issues. However, today when I exported a video to be rendered in 1920x1080p with H.264 format, I got the worst quality final video I've ever seen. I filmed my video files in 1920x1080p (like usual), and I clicked all the same buttons I normally do to export a video, but every HQ video I try to export looks horrible. I haven't clicked any crazy buttons or anything out of the ordinary.
I always export a video following this sequence:
File > Export > Add to Render Queue > Lossless > H.264 (quality format) > video output (make sure it's checked) > audio output (make sure it's checked) > OK > Output to Desktop
My render settings are always set as "best settings" including "full" resolution and "best" quality.
Now, when I click H.264, a "settings mismatch" pops up and says:
"Warning: Output file will be resized from 1920x1080 (1.00 PAR) to 320x1080 (6.00 PAR) to meet format constraints"
The rendering quality and playback quality within After Effects is great, but once the video is exported, it is horrible.
PLEASE HELP?! I have deadlines I need to meet!

Use the H.264 encoding presets in Adobe Media Encoder.
The H.264 export features in After Effects have been removed in later versions because of numerous problems.
