EOS R5 Mark II How to save burst pics in a single file as on the EOS R6 Mark II

[petero]

In my R6 Mk2 when I used the pre-shooting shutter burst, it stored all the images in one single file so I could select one or two images and export them (save them) and then delete the single file containing all the (unwanted) images in one go.

In my R5 Mk2 the images all appear as separate single images, so after I have chosen the images I want to save from a burst, how do I delete the many unwanted images in any way other than one by one, which will involve clicking buttons for tens (hundreds) of unwanted images and take literally many minutes to do in my camera!

If I can't capture a burst at a sporting event and then choose the "money shots" in one go, and delete the rest, I will spend ages deleting unwanted shots from the memory card, defeating the whole purpose of this feature...

Help please!

Unfortunately this is not possible with the EOS R5 Mark II. Pre-shooting was developed from the RAW burst function of the older cameras including EOS R6 Mark II. Some feedback from users was that RAW burst was less useful since the single RAW burst could not be processed in the normal way without extracting on camera or using the Canon DPP software. The result is that the EOS R5 Mark II and EOS R1 now save each image as separate files, making it easier to work with them in all sorts of software, but in your example with deleting on camera after extracting the best frames it's counter productive.

If you are already used to finding the best couple of frames from the RAW burst file, you could scroll through the set of images in playback on the camera and then "protect" them - RATE button can be configured as a protect button - and then delete all the images that are not protected using the delete images function in the menu - though this is "risky" as you might delete any images on the card that are not protected. Another option would be to use the RATE button to rate the successful shots in the sequence, and then you can identify them in computer software, or use a set of image search conditions on the camera to only show rated images.

Thanks for the comprehensive reply. It worked really well in the single raw burst format because I could delete most of the files in the camera and this made every subsequent step faster, but I accept that seemingly I am in a minority.

I used the protect function on my first foray, and discovered I could delete all the unprotected pics in one hit after I selected delete (the comprehensive instruction manual didn't tell me this or maybe I was looking in the wrong place). This effectively achieved a similar result, but then when I exported them to my computer, it wouldn't let me delete any of the photos (seemingly related to them being protected/locked) when I sent them to my NAS, and if I tried to put them into Apple Photos it wouldn't upload them there, telling me the files weren't in a format that it would accept (even after I went thru and tediously unlocked each jpg file on my mac). Oddly, if I replaced the jpg extension with jpeg, then it happily accepted them (but this was yet another tedious step).

Would be grateful for any help in how/why it thought the .jpg files were corrupted, or a way I can download them so they were properly accessible (without going thru multiple steps)

PS Absolutely loved the speed of processing in the R5Mk2, and the absence of banding under LED lights, which was a major issue with the R5 Mk2.

I had another idea that might be simpler.

Use the RATE button to add a star to the images you want to keep. You can customise the RATE button to only add a single star.

Then use the image search conditions in the playback menu to only display images without stars. Now you can delete in the normal way on the camera since only images that are not starred will be shown. The star ratings don't lock the files like the protect does.

If the files cannot be processed because they are marked read only in the file system, then "chmod +w *.JPG"  in a terminal window will make them writable.

To rename all the files in a directory on iMac in a terminal window, one may cd to directory containing JPG files and

mkdir subdirectory ; cd subdirectory ; ln -s ../*.JPG .
( for i in *.JPG
do
echo $i | | sed 's/.JPG$//'
done ) | ( while read name
do
mv -i ${name}.JPG ${name}.jpeg
done )

 I use ksh instead of bash as my login shell, but expect the above to also work in bash. (I use ksh because I have used it on every Unix system since 1987 and I am slow to change.)

The symbolic link will use very little additional storage.
