Export 790x592 .mov to 640x480 in QT 7.2 = choppy video playback

The specs to deliver a scene I scored are different than the original file. Original was H264 Codec 790x592 audio IMA 4:1. Needs to be delivered H264 Codec 640x480 with audio 48KHz 16bit.
I exported the file in QT pro 7.2 with the correct size and options. The sound is fine, but the video is not in sync - it jumps and stalls. Tried changing the options; same results so far.
Here is what I did.
I selected Movie to QT Movie and clicked on Options:
Under Video, I selected:
Compression - H.264
Dimensions - 640x480
Quality - High
Frame Rate - Current
Key Frames - Every - 24 Frames
Frame Reordering - yes
Scale - letterbox
Data Rate - Automatic
For Sound, I selected:
(Note: The only option I found giving me 48KHz 16 bit was Linear PCM. AAC is the standard, and I can select 48KHz, but there is no option for 16 bit.)
Linear PCM
Sample Rate - 48KHz
Channels - Stereo LR
Render
Quality - Best
Sample Size 16 bits

I fixed the choppy video.
Export File>Movie to QT Movie>Options>Video:
Frame Rate - Current
Key Frames - Automatic
Frame Reordering - Yes
Compressor Quality - Best
Encoding - Best Quality
Date Rate - Automatic
Options>Video:
Same as before
No more choppy video or sound.

"Ghosting" with 24p cam footage exported to .mov

I have a Sony HVR-A1U camera and I shoot everything at 24p. When I export the move files in imovie they always come out "ghosting" or looking jagged...anyone know what i have to do to fix this? also...this happens in every quality...except when i do cdrom...i cant see it then..but in full quality its definitely there...

Try exporting using 640x480 with square pixels.

MPEG 2 export is giving me 640x480 rez

I have exported a 720x480 QT out of FCP and am now trying to encode it using any of the presets for MPEG2. When I look at my source and the exported source movie QT says that it is 720x480 - and when I set the presets in compressor - it says it is 720x480 - but once it encodes it and dumps a movie - it comes out 640x480.
Anyone have any ideas or help?

Here's an update on the problem. DVDSP 3 just finished encoding the MPEG2 file internally, and it is correct.
When I take the exact same MPEG2 file out of the DVDSP project package and import it, as I would an MPEG2 file created in Compressor, it shows up with the duration incorrect.
The good news is I can encode MPEG2 files - in the background inside DVDSP.
The bad news is I can't use MPEG2 files created in Compressor. My normal production flow has been broken.
I think that once the Finder labels an MPEG2 file as a QuickTime movie, it alters some properties of that movie to incorrect values. That's why when it is imported as an asset into DVDSP, it shows up as being the wrong length.
This business of QuickTime Player "correcting" the frame size of the movie to allow for square pixels on a computer screen is just the tip of the iceberg.
QuickTime Player 6.x used to display the MPEG2 files at their true frame size.
QuickTime Player 7.x is making an automatic "adjustment" to the file, since Apple thinks we are all obviously too stupid to go to a menu and select "square pixels" if we open an NTSC formatted file. So they HAD to add this "fix" to OT Player
But it's doing something else, too, And that "something else" has really screwed up my production flow. Maybe it has something to do with the codec definitions in QT 7. But something's not right here.
I think I'm going to try dumping QT 7 and returning to v6.5. I need to get this fixed.
To heck with the cutting edge, I have work to do.

How many times can you "Export - Quicktime movie" the same ProRes 422 file until it starts to lose quality?

Lets say you are done with your project & you want an uncompressed copy of it as your master. If you keep importing it back into Final Cut Pro, & keep exporting (Quicktime movie), will it ever start to lose quality?

I've never seen a number given, but would think it is very high.
Apple describes ProRes here:
About Apple ProRes
And in that document says:
"while remaining visually lossless through many generations of decoding and reencoding."
I don't think I've ever seen degradation caused by recompression or multiple compassion, but as a workflow if you output a master file, then re-import it to add graphics and export that, you would only be 1 generation down from the master file. If you wanted to make multiple versions, you can always go back to, and re-import, the master file and make the changes, then export, so all you exports stay only 1 generation down from the master file.

How do I export a Movie to Quicktime? And do I need to?

Hello, how do I export a Movie in iMovie 11 to Quicktime, when the option is not listed?
I have created some short videos with Lavelier Line6 mic, which apparently records your voice in stereo on one track, I am told (although I can't see stereo tracks anywhere within iMovie project, it looks like one track below the picture - but then I wouldn't know what to look for as I'm new to this!).
I need to, I am told, export the final movie to Quicktime, in order to create a mono track rather than stereo. I can't see how to do this, as Quicktime is not an option in my Share menu (facebook etc is there, but not Quicktime).
Could someone advise me whether I need to do this at all? Is a movie soundtrack automatically converted to mono if there is only one track?
(Also, there is a small amount of hiss in the recording, which I have removed with background noise reduction, but could that hiss come from the unused track, does anyone know? And if so, what is the best way to get rid of that track? Of course, it may not be that at all! I don't really want to get into complicated removal of audio tracks into other software and then readding to the picture, if I can avoid it.)
Thanks for any advice you can give. Fran x

Use "Share to File".

FCP 7 Export Quicktime Movie Suddenly Stopped working

I use FCP7 on Mavericks 10.9.2. Working in Final Cut with raw ProRes 422 footage and wanting to export my sequence as Export Quicktime Movie. Worked fine until one day it just didn't. Final Cut exports a QT file that QT opens and immediately attempts (and fail) to convert. Then I get a message that QT cannot recognize file type, even though file is a .mov.
I send the file to the VLC media player, and it opens the file but only plays the audio. I have no idea why any of this is happening.
Using "Export Using Quicktime Conversion" I can still get the uncompressed ProRes 422 sequence out of Final Cut, but that's a pain. I want Command-E back. Any ideas?

If you love FCP7, you don't move UP to FPX - you move over to a new set of operational activities, a new vocabulary and a new media management structure. Notice the word "new" as in different, not "updated" as in a faster version of the same system.
If you want a 64 bit version of FCP7, look into Premiere Pro CC.
Best,

FCP "Export - QuickTime Movie" gamma shift

Above is an example of what happens when I do a direct export in Final Cut Pro, using the Export -> QuickTime Movie function. As you can see, the image is significantly brighter and the colors are a little more washed out (this image isn't particularly colorful, but trust me, it washes them out). I always thought the Export -> QuickTime Movie meant the image would not be compressed--that it was a straight export using the sequence settings.
The image you see above was shot natively in ProRes 422 (HQ) using an Arriflex Alexa. It has never been transcoded. The bottom image is what it looks like using Export -> QuickTime Movie. Totally unacceptable for a piece of professional software, if you ask me.
I can't express how infuriating this is, to have everything looking perfect in FCP and then exporting only to have it look like garbage. I've been able to play with gamma correction a bit and have gotten it PRETTY close to the original look, but this seems like a horrible workaround.
Anyone else know why this is happening? Is there a fix for this?
I'm working with FCP 6.0.6 and QuickTime 10.1.

Sure thing, Meg.
Here's a source clip with "approximate" gamma correction:
"Approximate" gamma correction makes the image look flatter within Final Cut Pro than it actually is.
Now, the very same clip and frame, but with gamma set to "Accurate" :
Now, things are switched. The exported image looks flatter than the source clip within FCP.
Here's another tidbit of info--the frame from my first post was professionally color graded and exported as a self-contained movie--so there were no filters, FCP or otherwise, being applied there. But the difference is just night-and-day to me.

How do I export FCP movie to a WMV format (Windows Media Player friendly)?

I am puzzled. How can I export FCP movie to a WMV format or Windows Media Player friendly?
Thanks in advance.

You need a third party app to do this... AVI is the only format that you can export from FCP that's windows media friendly... WMF's can be exported with flip4mac... http://www.flip4mac.com Probably the best of the apps...

Error exporting long movie in Premiere Elements 4

I just finished editing a movie in Premiere Elements 4. Every time I try to export the movie, it begins rendering, gets as far as about 15%, and then says "Export Error: Error compiling movie. Unknown error." This happens no matter what format I choose.
I've read that this problem can be caused by titles and transitions, of which this movie has both. But I think the problem is entirely due to the movie's length, which is six minutes and fifty-five seconds. I say this because if I split the movie into 25-to-50-second chunks, leaving all titles and transitions intact, all the chunks export with no problems whatsoever.
I'm not running any other programs while the movie exports, but that doesn't help.
The source files are MOV (and one PNG), and the resolution is 1920x1080. I want to export it at the same resolution, otherwise what was the point of shooting in that resolution? I'm running Windows Vista on a Samsung R522 laptop, if it helps.
For what it's worth, I did manage to successfully export the audio portion of the movie as a WAV file.
What can I do? My movie is due to premiere at a local arts festival in a few weeks, so I need to sort this out. I read somewhere that the ideal setup is to have three drives -- one for the source videos, one for running the program, and one to export the file onto. Will that help?
Many thanks for any suggestions you may have.
-Grant

Thanks Bill -- and thank you mods for moving the thread. I couldn't find an Elements forum so I assumed there wasn't one.
Actually, the progress bar in my version does tell you what frame it's on. When I tried to export it just now, it gave up around frame 2328 of 12447. Frame 2328 would be 01:17:18... which is the middle of a clip, with no titles, no effects, and no transitions, just ordinary video and sound. 30%, the number you suggested, gives frame 3738, which is 02:04:18, which is a different clip but the same deal.
The exact number varies from attempt to attempt anyway, which is why I think it's a "system memory" problem rather than a problem with a certain moment in the film. As I said, each part of the film exported fine on its own.
The videos are all MOV format, 1920x1080, ranging in size from 40 MB to 666 MB (maybe the devil is trying to stop me from exporting). There are 41 of them, giving a total of 11.9 GB. The single PNG is also 1920x1080 and 6.02 KB. The movie's audio is actually muted -- the audio that I successfully exported before was just the original audio from the raw clips.
I've got 55.3 GB of free space on my C drive and 580 GB of free space on my external drive; Premiere won't successfully export onto either of them.
Thanks for the link to the KB article, but I'd read it before and it didn't really help. As it says, "unknown error" really does mean just that. And it's clear that none of my clips or effects are problematic since they all exported fine when split into chunks.
I really do appreciate your help! I don't know too much about computers so if I didn't give you the information you were looking for please let me know.
Thanks so much,

Hi
Error -50 paramErr Error in user parameter list
Can there be any external hard disks - if so How is/are it/they formatted ? Must be Mac OS Extended (hfs) if used for Video.
UNIX/DOS/FAT32/Mac OS Exchange - works for most but not for VIDEO.
What this means in Your situation is above me.
• free space on internal boot hard disk? How much ?
Video codec
• streamingDV, AIC etc. (not .avi, .mp4, .m4v, .wmv etc as they are containers not codecs)
Pictures
• in what format ? .jpg, .bmp, .tif, else ?
Audio
• from where/what format ? iTunes, .avi, .mp3, .aiff, else ?
Trash the Preference file:
The "com.apple.iMovie.plist" file
Many users has not observed that there are TWO libraries.
• Library - at root level
• Library - in user/account folder - THIS IS THE ONE to look into
from Luke Burns
I fixed the problem.. but it was very, very strange. I had a very long section for credits and set the line spacing to 1.0.. for some reason this caused it. I removed it, and it worked fine. I put it back, and I couldn't preview or play the video.
I don't know why that could cause that big of a problem, but it did..

You need more free space on your hard drive.

After phone support from apple I ended up creating a new project and adding all 117 clips back in individually till I found out what clips flagged and would not allow me to export. I had 3 I deleted and replaced and everything works now 1hr after tedious work....
Where do Your material come from
• Camera
• External hard disk
• USB-memory
And all are connected so that iMovie can find it ?

Shorter clips than 1,5 sec might be one of the culptrits
Bengt cont.
Set-Up might differ
• Mac OS - most probably X.7 or more
• iMovie version - more than iM'11 v. 9.0.4
Action taken
• Finalizing project - I never do as I never understood the gain to do so
• Share as HD to iDVD - never give any gain but if it works the resulting DVD is less quality than if SD-quality was shared
fps - set
•I only use PAL (25fps)

The project could not be prepared for publishing because an error occurred. (-50)
What shall I do?? Can anyone help me out?
I have enough memory on my disk...

I cannot help you because your description of the problem is very vague. First what software did you update, iOS or iMovie. Second where are you trying to export iMovie Films to?

Hello, I am not able to export a movie in IMovie 10.0.1.

Everytime when I export a movie (for example as file, to I-Tunes or to the theatre) on my Mac Book Pro (from Februay 2013) I receive an error message. This Error Message is: "The Export of the Movie XY failed - Error during rendering of the video: -50" (I don't know if that is the exact english failurecode, because I am using the german version).
I allready reinstalled IMovie 2 times. Does anyone of you know an answer?
Best regards and thanks for help

There may be more than one cause for this error, but in most cases the project to be published includes short clips of less than about 1.5 seconds duration.
Duplicate the project. From the duplicate, delete the short clips and try to publish. If that doesn't solve the problem, see the comments of Didorx in this thread and of jguttenberg in this thread.

Export HD move to widescreen, is it possible?

I'm new to FCE. Used Premier Elements and others for years. I just edited a moved in 1080i HD and was able to create a dvd by sending the QuickTime movie version to iDVD.
Now I just want to create a file to keep as a separate movie. With Premier Elements on Windows and using DV, it was easy. Just create an uncompressed AVI and you keep good quality and universal editability. With FCE I have tried pretty much every export format and none produce a wide screen movie period. I've read through this forum and the only suggestion is to use Anamorpicizer which then requires that I buy QT Pro. (As an aside, I'm using FCE 3.0 on an Intel machine, so export to QT takes 25 hours for a 10 minute clip.)
I've tried the suggestion to create a DV sequence and copy my HD to that, still no wide screen QT file.
(My goal is to have a 'movie' clip I can use for future editing, easy viewing and conversion to iPod and other formats using iMovie which is a native app. I'm waiting for FCE 4.0 before upgrading, if it comes soon.)
Is there anyway to export widescreen from FCE? And is there any way to save it in MPEG2 for (inclusion on future DVDs without keeping all the HD source online) without having to buy a 3rd party codec?
thanks in advance.

So it looks like you want to export your finished movie into a format that can be edited by FCE in the future ... you've decided you don't want to keep your original clips and FCE Project file ...
Do File > Export > Using QuickTime Conversion
In the Save dialog box -
..... Select Format > QuickTime Movie
..... Select Use > Default Settings
Then click the Options button
In the Movie Settings window -
Select Video > Settings
..... Select Compression type > Apple Intermediate Codec
..... Select Compressor > Preset > HDV 1080i (you said you have a 1080i movie)
UNcheck "Prepare for Internet Streaming"
Click OK back to the Save dialog box
Give your movie a name, select the location to save, hit Save
This will give you a QT file encoded as Apple Intermediate Codec, and you will be able to import it back into FCE in the future when you want to do more editing.
If it were me, I would keep my original clips and FCE project file instead of doing what you are doing here.
As for your other questions, Anamorphicizer is a great little app but it's only needed when you have anamorphic DV material, which is not what you have here. FCE does not encode into MPEG2; that's done by iDVD, Compressor or other applications. If you want to output a video that you can re-edit in the future, you DON'T want to encode it into MPEG2.
You might find this article by Ken Stone of interest - Video to iPod
One final note - you really should upgrade to FCE 3.5. Version 3.0 will run on the Intel machines but not well. HDV takes a lot longer to export than DV, but 25 hours for a 10 min video is awful; it's probably because you're running FCE 3.0 on your Intel MBP. Version 3.5 is the universal binary version that was designed for the Intel Macs. How much RAM do you have in that MBP?
