Convert mpeg videos without changing original date

Hi
I'm trying to convert my mpeg videos to mp4 or other, so as i can import them to iphoto and display them in a slideshow. i want to play the videos and photos (jpegs) in the sequence they have been taken, so i would need to keep the original date and time in the file or keep somewhere the shooting date and time and have iphoto play them in this order (not the file date and time order, which possibility, by the way, i haven't found).
I noticed that when i convert, not only the file date and time are changed to the present, but the original date and time too.
Help is welcome.

Unlike photos movies do not have EXIF data to tell their dates, etc so the file date is used - I do not think that batch change date and time will fix this but it is worth a try - and try changing the date/time in the info window - but again I do not have great hope for that
Old Toad does a lot more with movies than I do - so he probably will have some ideas
You may have to do the slide show in something other than iPhoto - iMovie - Photo Presenter http://www.boinx.com/photopresenter/overview/ - etc

How to change field labels in CRM without changing original data structure

Hello, I wish I could change the label of the input-type fields that are visibile in the CRM Account search page.
The only way I have found so far is: go to the structure CRMT_BSP_SEAREQ_ACCOUNT
and change the short description of the component.
This is, anyway, very invasive, as I have to modify a SAP structure and I am asked an activation key.
I have gone through the PCUI but cannot find a way to change the labels, anybody has a hint?
At least, I would like to give the labels the same length so that the page is better organized, now all columns have different widths...

Sorry, I had not seen this previous answer

Preview - Rotate a picture and resave it WITHOUT changing the date?

Hi all,
Is there a way in Preview to save a picture, but have it NOT change the date of the picture? I usually run into this problem when I download pictures from my cellphone. Lets say I take some snapshots with my phone, some vertical some horizontal. My phone is dumb and doesn't rotate them, so they all come up the same way. What I usually do it select all the ones that need rotated, open them (all at once) in preview, select all of them push "rotate" and then do a save all. It will then "batch" rotate them, but now they come up out of order from the other ones because apparently whenever you "resave" anything from Preview, it saves it with the current date and time, vs the time the picture was originally taken.
Any ideas?
Thanks,
Scott

Hi Scott,
I'm afraid that it's not possible to preserve the file modification date when rotating an image with the Preview application.
One possible alternative would be using the Image Capture application to import your pictures and rotate them beforehand. Image Capture is less convenient than Preview, but it works and it sets the file creation, modification and even last access dates to the time the shot was taken (as recorded in the EXIF data of the JPEG image).
By the way, Image Capture performs the rotation without touching the actual data at all by simply adjusting the orientation tag (same as Preview does if you select "Save As" and "Rotate without modifying contents" on every single image).

Please help! is there a (easy) way to remove/copy files to ext HD without changing ANY date? An d how about e-mail attachments, they also change all dates

Dear forum readers
All I want is to copy my pics to another disk without MAC OS change the date on wich I shot them. Pics, sent to me by e-mail also loose there original date. I understand the difference between making a new file by copying, but I don't understand why it change when I remove them.

There are two kinds of metadata involved when you consider jpeg or other image file.
One is the file data. This is what the Finder shows. This tells you nothing about the contents of the file, just the File itself.
The problem with File metadata is that it can easily change as the file is moved from place to place or exported, e-mailed, uploaded etc.
Photographs have also got both Exif and IPTC metadata. The date and time that your camera snapped the Photograph is recorded in the Exif metadata. Regardless if what the file date says, this is the actual time recorded by the camera.
Photo applications like iPhoto, Aperture, Lightroom, Picasa, Photoshop etc get their date and time from the Exif metadata.
The problem is that the Finder doesn't work with Exif. You need to use an app that understands Exif.

How do i correctly convert mpeg videos so they work on my ipod?

is someone used by using mediacoder and can tell me how i should change the options to convert mpeg files so the video and sound works on my ipod?

I have the same problem - I thought I was the only one!
I converted my mpg videos using Itunes, then transferred them to my Ipod. But, when I go to play the videos, the video works fine, but there's no audio! I think this is a problem with the muxing of the audio and video tracks. I've heard that you have to extract the audio from the mpg file so you not only have a video file, but a separate audio file. Then I guess you mate the files togethter somehow in order for it to work on the Ipod. I've heard of a program that can fix this for Macs (ffmpegx), but I have a PC.

How can I change database date/time(Sysdate) without changing OS date

Hello all,
I have a need to change the sysdate on a database for testing purposes and need to set the database date to a future date(ex. 6/30/2009). I have 2 other instances on the same server so changing the OS date is not an option. I'm familiar with setting the sysdate to a fixed value, but doing so changes the date to a constant because I still need the time to elapse. I've searched the forum and cannot find a way to do this. Any help would be greatly appreciated.
Thanks,

Write your own sysdate function in pl/sql and create public synonym.
Sorry, It doesn't work.

How to render video without doubling original file size after minimal change

Using Photoshop CC, I am importing an otherwise finished H.264 960 x 540 video as a smart object and adding one tiny image for a few seconds and a transition. When I render the video, the file is over twice as large as the original (99KB to 224.6 KB). The only difference I can see is that audio saved in the original as 44.1 kHz mono, is saved in the new version as 48 kHz stereo. Please can you help me find out how can I render the video whilst maintaining the original quality without increasing the file size so much? Thank you.

You will have to read up on video compression on a general level. This is not something anyone can answer in a short forum post. It all comes down to what encoding settings you actually used when rendering, none of which you have tolds us. also be aware the recompressing an already compressed clip will always result in more compression artifacts and loss of quality with the same output settings. Inevitably you will actually want to use higher datarates to not completely degenerate your existing footage. Well, anyway, seriously do some web search. Plenty of stuff to find on the subject.

How can I permanently clip video without changing filmstrip order?

I have just recently upgraded from LR1.4 to 4.2 (Windows 7 OS) and one of the features I am most excited about is being able to work with video in LR. I started clipping videos but I know LR is non-destructive. This is great for my photography but with videos I am trying to actually make the files smaller by saving only the footage that I want. So I exported to the original folder and figured I could then just delete the original unclipped file and be all set. Only problem is the exported file now appears at the end of my filmstrip since it is dated today. If I stack it it goes with the original file, but since I was planning on deleting the original file that wont help me. This is different from the way photos behave (though I'm not exporting generally there, I'm editing a copy in photoshop, and that keeps the capture time metadata and thus stays in its appropriate spot in the filmstrip). I tried copying metadata from the original file or even manually changing capture time but nothing seems to be effective. Please help!

I use a much, much older iMovie so I don't know exactly how the new one works, but until somebody else replies... It may be re-encoding the whole .mp4 since some formats cannot be edited without doing that, and you would need to check something like format and quality settings to prevent it from saving to a much higher quality which won't actually make the quality any better than the original anyway.

PSE10 and PSE11 changing original date of image file on loading file to editor.

There seem to be a problem with PSE10 and PSE11 on my computer when loading image files digitized on my film scanner. When loaded into the editor the image file immediate takes today’s date and time, and thus changes place on the timeline. However, sometimes the original image file date remains intact, for no obvious reason. I find this very frustrating.
My setup is an HP computer running Windows7 Ultimate 64 bit, with i7 processor and 12GB memory. My film scanner is a Minolta Dimage Elite II working with a Windows XP-based computer, and data are transferred using memory stick.
Is there anybody out there able to advise me on what to do about the problem?
It might be mentioned that I have made tests with a fixed set of image files on several computers running WindowsXP 32 bit, and several versions of PSE , including PSE10, without seeing this problem.

If you have had a look at your other post,
Why does PSE10 change my file date to today?
you may be able to spot what can have triggered the updating of the catalog. There are too many date types in the exif, some of them are misleading. What is really interesting for a scan? For me (familiy history, genealogy) it's the supposed 'Date taken' or 'CreateDate' to display file chronogically. The file date in the OS is useful for backups.
It's possible that the date digitized has some meaning for you.
If you want to compare the different dates shown by John R Ellis in the Organizer database with those you see in an exif browser (or the properties in the editor, or the information panel in the organizer), you have to note that the 5 types of dates stored in the catalog database are;
-pse:FileDate
-Pse:FileDateOriginal
-xmp:CreateDate
-pse:TagDate
-pse:LastOrganizerModifiedTime
What's important to troubleshoot your problems is to find what operation triggers the updating of the catalog from the files or vice versa.
That can be: Update thumbnail, Write Metadata to files or...

How to convert MPEG videos for use on iMovie?

I filmed my drama assignment with my friend on her video camera, she gave me all the files on a USB and when I got home to start editing on iMovie, it says: iMovie cannot open files in the “MPEG movie” format.

I forgot to mention in a strange way there is not a straight standard format used by cameras as I discover In iMove and Final Cut Express. Mpeg is pretty standard but can be different. For example AVCHD or AVCHD Lite, Motion Jpeg on Panasonic. Each Camera uses similar names but the compression format maybe different and not compatible with iMovie. This why I like Toast, it converts almost anything to a useable format. But if your starting out the Camera Brand and Model is the key to finding compatibility with iMove. Since I have not used iMove in a while and don't know the new version go to the forum with Camera etc. and ask about compatibility. But Toast with some tries will most likely give you what need. This can be frustrating but you'll get there, it may take a little time. Also open the folder with files to see exactly what you've got. You really need to know exactly what you've got. I hope QuickTime work out for you

How do I change the value labels in a line graph without changing the data in the source table?

Where the graph values show 1 I want them to change to text (different each time). Is there a way to make this happen?
Also, is there a way to connect the series markers - circles - with solid lines even if there is no data in the table. E.g from 1.5 to 2.5 a solid line even if there is no data under 2.0?
Is there perhaps a better way altogether to achieve this graph?
Thanks.

HI Mick,
Sounds like something that could be achieved with no "graph" at all.
This is a combination of a table and an inserted shape (line). Enter the dates as the goals are achieved. Here's a second image of the same 'chart,' taken before the table grid was whited out:

Edit photo in album without changing original

In iPhoto '08, it seems like any photo that I edit in an album also edits the original. This is why I stopped using one of the earlier versions of iPhoto. It seemed like this was fixed in iPhoto 6, so that iPhoto would automatically preserve the original and save the changes in a copy of the photo.
Is there a setting that can be changed in the preferences somewhere? If I'm working on two albums (i.e. one for each child) I often want to use the same photos but crop them differently, and I'd rather not have to remember to make a copy any time I do so.

No, all occurrences of a photo in the library other than in an event is just an alias of the original or the edited version. Change one and you change all.
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 created 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 and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Converting upright video without distortion

How do I put upright video into iMovie without the footage distorting?

First you drag the clips that you want into the project from the Event.
Select a clip. Open the Rotate, Crop, Ken Burns Tool.
Then you have two choices.
FIT will place your whole vertically oriented clip into the movie, and will fill in on either side with black bars. (Letterboxing).
CROP will make your vertically oriented video fill the landscape screen by chopping off the top and bottom of your clip.

Grab frames from mpeg video without framegrabber card?

How do you speed up a part of a video without changing the av sync?

I tried to speed up part of my video (for the chipmunk voice of course) but then throughout the rest of my video that was in real time, the av sync was completely not synchronized. Additionally, imovie did not show evidence of this problem, when I posted it to youtube the av sync was completely off! PLEASE HELP, IT WOULD BE GREATLY APPRECIATED

here's real code:
//where flv is a video displayobject (eg, an flvplayback component)
var bmpd1:BitmapData = new BitmapData(flv.width,flv.height,false);
var bmpd2:BitmapData = new BitmapData(flv.width,flv.height,false);
var bmp1:Bitmap = new Bitmap(bmpd1);
var bmp2:Bitmap = new Bitmap(bmpd2);
addChild(bmp1);
bmp1.x=0;
bmp1.y=flv.height;
addChild(bmp2);
bmp2.x=stage.stageWidth/2;
bmp2.y = flv.height;
this.addEventListener(Event.ENTER_FRAME,f);
function f(e:Event):void{
bmpd1.draw(flv,new Matrix(),null,null,new Rectangle(0,0,flv.width/2,flv.height),true);
