Files down loaded in wrong order

Has anyone else experienced this? When downloading sequences taken on my 5d3 at maximum frame rate, the shots show up in the correct order when reviewed in the camera, but when downloaded in Bridge they get mixed up, often considerably. I have had sequences that should be 1,2,3,4,5,6,7,8 turn into 1,2,5,3,4,7,6,8...most confusing.
Is there something I need to do in Bridge? Or anywhere else?

Thanks to anyone who can shed some light on this.

I'd say check the "Time" Exif -- I've seen shots done at "High Speed Continuous" where a bunch shot in the same second get mixed up when the software sorts the shots by Capture Time. The way out would be to sort them alphabetically/numeric​ally, I believe, if this is what you're seeing.

There are various ways to sort your images. Go to "view"- "sort" and choose whatever way you would like to view them.

Thanks Tony...I'll take a look but when you're shooting 6 frames a second all the times are the same. The trick is to find numbers from the camera sequence that are consecutive....!

It could be that because I use a different numbering system from the default, that may be causing the problem. If I let the default Canon numbering system have it's way it should get it right, but my numbering and filing system works perfectly apart from during the high-speed continuous, and I am reluctant to change as it adds another process....!

Of course. The point is that by the time the camera has downloaded the image files the numbers have been muddled. All the "sort" instructions in the world won't change that. View and sort were the first things I tried, but if the numbers are out of sequence to the correct order of the images, they don't change.

Yeah, therein lies the rub -- when you rename/renumber the files then, well, things can get screwed up. The only way I know of remedying this is to manually select the proper sequence, sorting the photos in "user defined order", then select them and rename/renumber them again!

Sort by date modified. It probably only sorts to the second though, which is why super high speed will be out of order. Just drag into order and rename, or sort based on filename.

I'm just curious, what kind of in-camera numbering scheme are you using that does not provide consecutive sequence numbers?

I'm not renumbering in camera, but when I download. As I said I've used the same system for years and am always serching and sorting using whatever criteria I choose...it's only the images taken in high-speed continuous sequence that get screwed up.

Gotcha. Of course if it turns out that if I use the camera default numbers and they stay in the correct sequence, then I can download that way then re-name to my system. A nuisance though!

Cheers, Tim. Tried date modified but it seems that it doesn't register fractions of a second! As for sorting by file name...well that's the rub...it screws up the order. So I will have to drag into order and rename as you and Tony suggest.

Edit: I have used the same downloading and file numbering system through the 5D and 5D Mk2 days...thousands of files, and have never had this problem.... it's only when I use 6 frames/sec on the 5D3 that it happens.

Wondering the same.

FAT file systems have a 16-bit number (0..65535) for storing the date. And another 16-bit number for storing the time.

The time gets split into:
- 7 bits (0..127) for year - base year 1980, so real range 1980 .. 2107.
- 4 bits (0..15) for month
- 5 bits (0..31) for day of month

- 5 bits (0..31) for hours.
- 6 bits (0..63) for minutes.
- 5 bits (0..31) for seconds - but there are 60 seconds in a minute, so FAT only stores even seconds.

So in the end, a high-speed shoot will group together all images taken during two-second intervals into the same stored time stamp in the file system on the memory card. It is only in the Exif data inside the image where you will have individual time stamps with resolution enough to always separate the photos on time.

Thank you for your interest.

See my last post...I'm not changing the way the camera numbers the files...I do nothing till the download when in response to the bridge menu I name a folder then the first few letters of the individual filename, like mar28 for pics taken on March 28. Bridge then supplies the sequential numbers. As I said, it's worked fine for years and only goes awry when shooting at 6 fames/sec.

Thank you....that explains a lot.

Bearing that in mind, when I have used high speed continuous I will let the camera take it's best guess! When I review the images on the camera LCD screen they stay in the correct order...it's just the downloading that alters them, and your information mnakes this more clear. If I don't interfere by adding my own numbering system it may keep the sequence in order. I will try it and let you know.

Thanks again for the trouble to explain that!

Just to be clear....

Are you using the Photo Downloader module (The "Get Photos from Camera..." menu command) in Adobe Bridge to download your files from camera to computer? Have you also configured Photo Downloader to concurrently rename your files to your custom format as they are downloaded?

Yes, sort of.
When I put the CF card in the card reader Bridge automatically launches the window that either offers default file names (date etc) or invites the user to use their own system. My procedure over a number of years has been to name a new folder based on year,month,day, then the files to go into that folder have a date and number, as in mar28_0022.

Am I doing something wrong? It works perfectly in every other way, and has for several years.
